摘要: A uniaxial viscoelastoplastic model that can describe whole creep behaviors of asphalt sand at
different temperatures was presented. The model was composed of three submodels in series, which
describe elastoplastic, viscoelastic and viscoplastic characteristics respectively. The constitutive equation
was established for uniaxial loading condition, and the creep representation was also obtained. The
constitutive parameters were determined by uniaxial compression tests under controlled-stress of 0.1 MPa
with five different test temperatures of 20, 40, 45, 50 and 60 degrees C. Expressions of the model
parameters in terms of temperatures were also given. The model gave prediction at various temperatures
consistent with the experimental results, and can reflect the total deformation characterization of asphalt
sands.

摘要: The reaction of di-2-pyridyl ketone with copper dichloride dihydrate and tartaric acid in water
afforded the title compound, [Cu(C11H10N2O2)(2)] C4H4O6. The Cu-II atom lies on an inversion center
N, O, N'-chelated by two di-2-pyridylmethanediol ligands in a tetragonally distorted octahedral geometry.
The tartrate anion is also located on an inversion center and has disordered hydroxyl groups, each with an
occupancy factor of 0.5. The hydroxyl groups of the complex cation are hydrogen bonded to the
carboxylate groups of the anion, thus connecting the two building units.

摘 要 : The title compound, [Cu-2(CN)(SCN)(C10H8N2)(2)](n), contains two crystallographically
independent Cu-I atoms, each in a distorted tetrahedral geometry. Each Cu atom is coordinated by a
bidentate chelating 2,2'-bipyridine ligand. A bridging cyanide anion links the two Cu(2,2'-bipyridine) units
to form a binuclear unit. Adjacent binuclear units are connected by a thiocyanate anion into a onedimensional helical chain along [010]. The cyanide anion is disordered, with each site occupied by both C
and N atoms in an occupancy ratio of 0.61 (5):0.39 (5). The S atom of the thiocyanate anion is also
disordered over two sites, with occupancy factors of 0.61 (3) and 0.39 (3). There are pi-pi interactions
between the pyridyl rings of neighbouring chains [centroid-centroid distance = 3.82 (1) angstrom].

标题: Mechanism for the rapid motion of the Qianjiangping landslide during reactivation by the first

摘要: The first impoundment of the Three Gorges Dam reservoir in China started from a water surface
elevation of 95 m on June 1, 2003 and reached 135 m on June 15, 2003. Shortly after the water level
reached 135 m, many slopes began to deform and some landslides occurred. The Qianjiangping landslide is
the largest one; it occurred on the early morning of July 14, 2003 and caused great loss of lives and
property. Field investigation revealed that, although failure occurred after the reservoir reached 135 m, the
stability of the slope was already reduced by preexisting sheared bedding planes. To study the mechanism
of the rapid motion of this reactivated landslide, two soil samples were taken from a yellow clay layer and a
black silt layer in the sliding zone, respectively, and a series of ring shear tests were conducted on the
samples. One series of ring shear tests simulates the creep deformation behavior, while the other series
simulates different shear rates. Conclusions drawn from analysis of the ring shear tests indicate that the
mechanism of the rapid motion of the reactivated landslide was caused by the rate effect of the black silt
layer during the motion phase after the creep failure. The yellow clay layer did not play any important role
in the rapid motion in the 2003 event.

摘要: Active contour method is a powerful approach for object contour extraction. This paper presents a
new object contour extraction method, which combines the level set evolution with the support value filter.
It analyzes image under the least squares support vector machine (LS-SVM) framework and uses the
support values to represent salient features underlying image. The Gaussian filter, used in conventional
level set method to compute the edge indicator, is replaced by the support value filter deduced from the
mapped LS-SVM. The level set evolution method is implemented on the feature image obtained by
convolving the support value filter with the original image. Experiments are undertaken on the synthetic
and real images. The experimental results demonstrate that the support value filter can provide a good
estimate for the optimal step size in a gradient descent algorithm and the proposed method has advantages
over the direct level set evolution method in converging speed and contour extraction accuracy. (C) 2008

摘要: This paper deals with some finite-time control problems for uncertain discrete-time linear systems
subject to exogenous disturbance. Sufficient conditions are presented for finite-time stabilization via state
feedback. These conditions can be reduced to feasibility problems involving linear matrix inequality (LMI).
A detailed solving method is proposed for the restricted linear matrix inequalities. Finally, an example
illustrates the proposed methodology. (c) 2007 Elsevier B.V. All rights reserved.

标题: A variational inequality formulation for unconfined seepage problems in porous media

摘要: In the existing variational inequality formulations for the unconfined seepage problem in porous
media, the seepage point, namely the exit point of the free surface, is a singular point and how to locate the
seepage point exactly has been an open issue. By generalizing Darcy's law applied solely to the saturated
zone in an earth dam to the entire dam including the no-flow zone, a new variational inequality formulation
is presented. The new formulation imposes a boundary condition of Signorini's type on the potential
seepage boundary and the seepage point turns out to be such a point that makes both inequalities in
Signorini's complementary condition become equalities. Singularity of the seepage point is accordingly
eliminated. A strategy is developed for overcoming the mesh-dependency in the finite element
implementation. (C) 2007 Published by Elsevier Inc.

摘 要 : The title compound, [Ni(dcbp)(H2O)(2)](H(2)dcbp = 2,2'-bipyridine-4,4'-dicarboxyacid), was
synthesized under hydrothermal conditions. The structure was determined by single-crystal X-ray
diffraction and further characterized by elemental analysis, IR, and TGA. The compound crystallized in an
orthorhombic system, P2(1)2(1)2(1) space group, a = 6.7665(7) angstrom, b = 12.9047(14) angstrom, c =
13.1848(15) angstrom, beta = 90 degrees. In the compound, each Ni(II) atom exhibits a six-coordinated
distorted octahedral geometry. Interestingly, carboxylate group from dcbp ligands bridges between adjacent
Ni(II) atoms giving rise to unprecedented interweaving of hetero-chiral single helical chains into a 3D
chiral (10, 3) framework.

摘 要 : Ferroelectric Bi3.25La0.75Ti3O12 (BLT) and Bi3.15Nd0.85Ti3O12 (BNT) thin films were
fabricated on Pt/TiO2/SiO2/Si (100) substrates by a modified sol-gel technique. X-ray diffraction indicated
that these films were of single phase with random polycrystalline orientations. The surface morphologies of
the films were observed by scanning electron microscope, showing uniform, dense films with grain size of
50-100 nm. Well-saturated hysteresis loops of the films were obtained in metal-ferroelectric-metal type
capacitors with Cu top electrodes at an applied voltage of 400 kV/cm, giving the remanent polarization
(2P(r)) and coercive field (2E(c)) values of the films of 25.1 mu C/cm(2)and 203 kV/cm for BLT, and 44.2
mu C/cm(2) and 296 kV/cm for BNT, respectively. Moreover, these capacitors did not show fatigue
behaviors after up to 1.75x10(10) switching cycles at the test frequency of 1 MHz, suggesting a fatigue-free
character. The influences of the La3+ and Nd3+ doping on the properties of the films were comparatively
discussed.

标题: Laser induced gratings enhanced by surface-charge mediated electric field in doped nematic liquid

摘要: The optically induced grating enhanced by dc electric field in nematic liquid crystal (LC) doped with
copper porphyrin is studied. The reorientational effect of the LC was not observed for the writing beams
with the intensity up to 500 mW/mm(2), but the threshold of the reorientation was reduced to 1 mW/mm(2)
with the assistance of an electric pulse applied to the LC. The low threshold for the induced grating can be
retained even after switching off the dc pulse, indicating that an induced field inside the LC is present to
sustain the low threshold operation for the induced grating. The low threshold operation does not persist by
short circuiting of LC electrodes. The underlying mechanism is explained by an optical surface-charge
mediated effect. (c) 2008 American Institute of Physics.

摘要: 1,8-Bis[(3-aryl)-s-triazolo[3,4-b]-[1,3,4]thiadiazole-6-yl]octanes2 were synthesized in high yields by
reaction of 3-aryl 4-amino-5-mercapto-1,2,4-triazole 1 with sebacic acid in the presence of POCl3 and
tetrabutylammonium iodide as catalyst. The structures have been established on the basis of elemental
analysis and spectral date. The preliminary antibacterial tests showed that most of them were effective
against S.aureus, E.coli and B.subtilis. 2b, 2c, 2d, 2n and 2o exhibited good fungicidal activities against
Cerospora beticola sacc.

摘要: In this paper, we investigate a prey-predator model with diffusion and ratio-dependent functional
response subject to the homogeneous Neumann boundary condition. Our main focuses are on the global
behavior of the reaction-diffusion system and its corresponding steady-state problem. We first apply
various Lyapunov functions to discuss the global stability of the unique positive constant steady-state. Then,
for the steady-state system, we establish some a priori upper and lower estimates for positive steady-states,
and derive several results for non-existence of positive non-constant steadystates if the diffusion rates are
large or small.

摘要: A novel nano-Si dispersed composite containing lithium-rich component (lithium orthosilicate, etc.)
has been prepared and investigated as a potential anode material for lithium-ion batteries. The composite
was synthesized by mechanochemical reduction of SiO Using lithium metal as reducing agent and graphite
as grinding aid, further vacuum heat-treatment was performed to improve interfacial stability between
different components. Compared with pure SiO and intrinsic silicon electrodes, the as-obtained composite
electrode exhibited greatly improved cycling performance with a remarkable value of the first coulombic
efficiency. The superior electrochemical properties were attributed to small absolute volume changes of
nano-silicon particles, highly distribution of silicon phase and better buffering action of lithium-containing
components. (C) 2007 Elsevier B.V. All rights reserved.

摘要: This study was designed to explore the role of toll like receptor 4 (TLR4) in myocardial ischemia
reperfusion injury (MI/RI). Male Sprague-Dawley rats were randomly divided into sham and IR groups
(36/group). The rats were sacrificed at various times following reperfusion ( 0, 1/2, 1, 2, 4 and 8 h). The
histopathological and ultrastructual changes in the myocardium were examined under a light microscope
and a transmission electron microscope. The TLR4 protein and mRNA expression were detected by
immunohistochemistry and real-time reverse transcription polymerase chain reaction, respectively. The
levels of tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 in the myocardium were measured by
enzyme-linked immunosorbent assays. The injury to the myocardium was severe in the IR group, and there
were no significant improvements in histopathology and ultrastructure of the myocardium during the first 8
h following reperfusion. Positive TLR4 protein staining was observed in both sham and IR groups. The
TLR4 protein levels were significantly increased in the IR group, peaking at 1 h post reperfusion.
Additionally, the TLR4 mRNA levels were also up-regulated in the IR group. At all time points, IR rats had
significantly higher TNF-alpha and IL-6 levels than the sham rats (P<0.05). The TLR4 mRNA expression
positively correlated with the levels of TNF-alpha and IL-6 (r=0.728 and 0.676, P<0.01). Myocardial TLR4

role in MI/RI by increasing TNF-alpha and IL-6 expression.

标题: Spatial variability in soil heat flux at three Inner Mongolia steppe ecosystems

摘要: Closing the energy budget at flux measurement sites is problematic, even when the fetch extends
over flat, homogeneous surfaces with low vegetation cover. We used the residual energy balance and
ordinary least square (OLS) linear regression methods to quantify spatial variability in soil heat flux
contributing to energy balance closure (EBC), by deploying a mobile energy system within the footprints of
three Eddy-covariance towers located in the steppe of Inner Mongolia, China. The EBC at the study sites
had a daily average residual of 819 W m(-2) with OLS slopes of 0.83-0.96. The EBC was better achieved at
the wet site than at the dry site. The spatial variability in soil heat flux was 48 W m(-2) (13% of R.) during
the day and 15 W m(-2) (34%) at night, with an average of 29 W m(-2) (24%) across the three sites. A 9%
OLS slope difference due to this variability was recorded from our eight plot measurements. A large
amount of missing energy (110 W m(-2) at peak) could occur with decreasing OLS slope of 23% across the
three grassland sites when soil heat flux is not taken into account. In particular, heat storage in the top soil
layer not only influenced the magnitude of EBC, but also adjusted soil heat flux to match the 'truth
schedule'. Heat storage in the top soil layer comprised half of the soil heat flux when the heat flux plate was
deployed at a depth of 30 mm. if this part of heat storage was neglected, the residual of EBC would
increase as large as 60 W m(-2) with OLS slope decreasing 9%. Comparing them with the multiple-location
soil heat flux measurements, the single-location measurements from near the Eddy-covariance towers
obtained a slightly better EBC with the OLS slope increasing by 4%. (C) 2008 Elsevier B.V. All rights

标题: Titania-activated bleaching clay composite photocatalyst: Preparation and photocatalytic activity

摘要: Titanium dioxide-activated bleaching clay composite photocatalyst was prepared by acid-catalyzed
sol method, and characterized by using XRD, XPS, SEM and UV-Vis techniques. Results of structural
characterization indicate that some TiO2 particles insert into the lattice layer of the activated bleaching clay,
resulting in larger specific surface area for composite photocatalysts. UV-Vis absorption spectra reveal that
titania-activated bleaching clay has stronger absorption band and the absorption edge is red-shifted
comparing with pure TiO2. The optimal parameters for the preparation were obtained by adjusting the ratio
of TiO2 in composite photocatalysts and the calcination temperature. Experimental results show that when
the theoretical loading of TiO2 is 66% and the ;calcination temperature is 400 degrees C, the as-prepared
sample exhibit high photocatalytic activity, i. e. the decoloration ratio of methyl orange solution is above
90%, and COD removal of cigarette factory wastewater is 75%.

摘 要 : Mono(iminophosphorane) 4 was selectively prepared from the reaction of
3,4-diaminothieno[2,3-b]thiophene 3 with excess triphenylphosphine, C2Cl6, and Et3N due to
intramolecular double hydrogen bond formation. Mono(iminophosphorane) 4 reacted with aromatic
isocyanates to give stable carbodiimides 8, which were further treated with aliphatic secondary or primary
amines to give 2-amino substituted thieno[3',2':4,5]thieno[3,2-d]pyrimidin-4(3H)-ones 10 or 12 in the
presence of a catalytic amounts of EtO-Na+. However, in the presence of a catalytic amounts of potassium
carbonate,
the
carbodiimides
8
were
transformed
into
previously
unreported
5H-2,3-dithia-5,7-diaza-cyclopenta[c,d]indenes 13 via direct cyclization in high yields. The reaction of
carbodiimides 8 with phenols in the presence of a catalytic amounts of potassium carbonate gave a mixture
of 2-aryloxy substituted thieno[3',2':4,5]thieno[3,2-d]pyrimidin-4(3H)-ones 14 and 13. X-ray structure
analysis of 10m supported the structure and the proposed reactivity of amino group. (C) 2008 Elsevier Ltd.

摘 要 : The reaction conditions for the determination of bovine serum albumin (BSA) using
o-hydroxyphenylfluorone (o-HPF) as fluorescence probe reagent were studied. In the B-R medium at pH 7.
90, o-HPF could react with BSA, producing a stable complex compound which resulted in fluorescent
quenching of this binary system The quantitative assay was carried out based on the relation between the
degree of fluorescent quenching and the additional amount of BSA. The method has advantages of good
selectivity, stability and simplicity. The linear range of o-HPF fluorescence spectrophotometric method was
1. 32-18. 54 mu g . mL(-1). Moreover, the mechanism of the reaction BSA and o-HPF was discussed, and
the quenching constant, and the thermodynamics constant of the fluorescence effects were calculated. The
results showed that the nonconvalent binding forces were the binding force between o-HPF and BSA, and
the quenching of BSA to o-HPF was probably a single static quenching process.

摘要: Coordinated collective motion of groups of autonomous mobile robots is studied. A qualitative
analysis for the collective dynamics of multiple autonomous robots with directed interconnected topology
using nearest neighbor rules is given. A necessary and sufficient graphical condition is proposed to
guarantee that the headings of all robots converge to the same heading. The graph having a globally
reachable node plays a crucial role in convergence analysis. Furthermore, we show that the globally
reachable node having no neighbors serves as a group leader as a special case.

摘要: In this note, the global asymptotic stability for delayed recurrent neural networks is addressed with a
new Lyapunov-Krasovskii function. New delay-independent linear matrix inequality (LMI)-based
conditions for global asymptotic stability are derived. A key feature of the new approach is the introduction
auxiliary matrices, which can provide useful and less conservative results. This feature also enables us to
cast a series of previous LMI-based results into even more general framework, logic flow of ideas and
comparisons are thus easily shown. Three numerical examples show the effectiveness of the proposed
method.

摘要: A binary lithium-storage composite anode material containing nano-sized silicon and tin particles
was synthesized by an in-situ mechanochemical reaction using silicon monoxide.. tin monoxide as oxidants
and lithium metal as reductant. Compared with other silicon-containing or tin-containing composites using
commercial silicon and tin powders as active particles, the as-obtained composite could deliver a reversible
capacity of 550 mAb . g(-1) for up to 30 cycles with capacity retention above 84%. The superior
electrochemical properties were attributed to small absolute volume changes of nano-sized lithium-storage
particles, narrow distribution of nano-sized particles and improvement of electric contact between active
particles after addition of tin particles.

摘要: 2,5-bis[(3-aryl)-1,2,4-triazolo[3,4-b]-[1,3,4]thiadiazole-6-yl]thiophenes 2 were synthesized in high
yields by cyclization of 3-aryl 4-amino-5-mercapto-1,2,4-triazole 1 with thiophene-2,5-dicarboxylic acid in
the presence of POCl3 and tetrabutylammonium iodide as catalyst. The preliminary antibacterial tests
showed that most of them were effective against S. aureus, E. coli and B. subtilis. Compounds 2b, 2c, 2d,
2m, 2n, and 2o exhibited promising antibacterial activity. Compounds 2 were screened for their fungicidal
activities against Gibberella zeae, Cerospora beticola sacc, Physalospora piricola and Pellicularia sasakii.
Compounds 2b, 2c, and 2d showed a high degree of inhibition against Cerospora beticola sacc.

标题: Analysis of charged hadron multiplicity distributions at RHIC

摘要: It is demonstrated that with Heinz's collective flow model charged particle distributions at AGS and
lower SPS energies (less than 20 GeV/n), can successfully be analyzed, but that the model fails for the
RHIC data. Heinz's model calculation underestimates the tails of the charged particle distributions from
RHIC, the discrepancy becoming bigger as the energy increases. To study the multiplicity distributions at
RHIC we develop the so-called "Thermalization Component Model", which is based on Heinz's collective
flow model. It is realized that the limitation of phase space of collective flow can be reflected in that of the
thermalization region. By comparing the contributions of particle production from the thermalization
regions at different energies and different centralities, we can deepen our understanding of the features of
collective motion at RHIC.

摘要: The performance of an optical code division multiplexing access (OCDMA) system employing the
differential phase shift keying (DPSK) data format and turbo code is investigated and simulated. A
bandwidth-limited coherent time spreading (TS) OCDMA system is considered. Theoretical results show
that performance degradation due to bandwidth limitation could be effectively restrained by the application
of the DPSK data format in a coherent OCDMA system, and further performance improvement could be
achieved by incorporating turbo coding into the OCDMA system.

摘要: The paper discusses rainfall as a dynamic parameter in terms of the load-unload response theory,
using the Xintan landslide in China as a case study. The computational results show that an abrupt jump
occurs in the curve of the load-unload response ratio just before the landslide takes place. This indicates the
potential of the dynamic parameter of rainfall for the prediction of colluvial landslides.

标题: Analysis of a sort of unusual mal-operation of transformer differential protection due to removal of
external fault

摘要: Several cases of mal-operation of transformer differential protection with second-harmonic blocking
after clearance of external fault are reported. These mal-operations all occurred at the nonrestraint region of
percentage restraint plane. The previous theory cannot be utilized directly to analyze this phenomenon.
Therefore, a mathematical model for analyzing the transient course of external fault inception and removal,
together with the CT model involving the magnetic hysteresis effect, is proposed in this paper. It is proved
that the magnetic linkage of one CT core can be pushed into the region nearby the saturation point by the
high fault current with aperiodic component. As soon as the external fault is removed, the magnetic linkage
formed by the primary current with low amplitude is not high enough to pull the operating point of the
magnetic linkage back to the linear region. This phenomenon is named as CT local transient saturation,
which results in the big measuring angle error and relative smooth waveform. In this case, the transformer
differential protection using second harmonic blocking inevitably mal-operates. This point of view is
verified with the simulation tests.

摘要: Understanding of spatial and temporal behaviour of interacting species or reactants in ecological or
chemical systems has become a central issue, and rigorously determining the formation of patterns in
models from various mechanisms is of particular interest to applied mathematicians. In this paper, we study
a bimolecular autocatalytic reaction-diffusion model with saturation law and are mainly concerned with the
corresponding steady-state problem subject to the homogeneous Neumann boundary condition. In
particular, we derive some results for the existence and non-existence of non-constant stationary solutions
when the diffusion rate of a certain reactant is large or small. The existence of non-constant stationary
solutions implies the possibility of pattern formation in this system. Our theoretical analysis shows that the
diffusion rate of this reactant and the size of the reactor play decisive roles in leading to the formation of
stationary patterns.

摘要: Samples of two cores, Cores M5-5 and M7-4 in the Bohai Sea were analyzed in isotopes, grain size,
heavy minerals, chemical compositions, and 14 C dating to reconstruct the sedimentation during the
Holocene. Abrupt change in carbon and oxygen stable isotopes was recognized at Core M5-5 at about 6400
a BP, which was likely due to the intrusion of the Yellow Sea Warm Current (YSWC) extension into the
Bohai Sea. At Core M7-4, sediments between 5900 and 6600 a BP (150-260 cm depth) became
coarse-grained, containing rich garnet, high manganese content, and nil autogenic pyrite, indicating a very
dynamic sedimentary event during which the ambience was transformed from reductive to oxidative, and
sedimentation boosted. Meanwhile, the YSWC had invaded into the Bohai Sea indicated by rich planktonic
foraminifera in this event. (c) 2008 Elsevier Ltd. All rights reserved.

摘 要 : The lanthanide coordination polymer, Tb-2(tda)(3)(H2O)(2), and it's single crystals was
self-assembled from thlodiglycolic acid (H(2)tda) and corresponding terbium(III) chlorides under
hydrothermal conditions. Single-crystal structure shows that the compound presents a 2D network, an
edge-sharing dinuclear polyhedral [Tb2O16] was found to be the building unit of the network, :in which the
eight-coordinated TbO8 and nine-coordinated TbO9 cores exhibit distinct coordination environments, that
is, one is in a distorted monocapped square antiprism surrounding and the other is in a triply capped
trigonal prism. The H2tda ligand exhibits two different coordination modes in framework, including mode
a: Bis "syn, syn-bridgilng bidentate, chelating-bridging tri'dentate", mode b: Bis"chelating-bridging
bidentate, syn, anti-bridging bidentae". Eventually, through the Weak interaction, the networks formed 3D
supramolecular architectures. Photoluminescence measurements indicate that the terbium compound is a.
strong green emitter in the solid state at room temperature. Crystal data for the complex: triclinic, space

摘要: The effect of vanadium carbide (VC) addition on the sinterability and the microstructure of ultrafine
Ti(C, N)-based cermets consolidated through spark plasma sintering (SPS) was systematically investigated
using optical microscope, scanning electron microscope (SEM) with X-ray energy dispersive spectrometer
(EDS), X-ray diffractometer (XRD) and transmission electron microscope (TEM). Our results reveal that
the addition of VC increases the porosity of sintering body and depresses the sinterability of Ti(C, N)-based
cermets. It is also found that the VC addition has a significant influence on the microstructure of ultrafine
Ti(C, N)-based cermets, which inhibits the dissolution of titanium-containing compounds and the formation
of inner rim phase and outer rim phase, thus preventing from grain growth. Owing to the depressed
dissolution and precipitation, nitrogen liberation is mitigated, therefore resulting in less amount of graphite
phase in the samples. In substance, VC changes the solubility of metallic elements in the binder, which
makes more elements of Mo and W to be reserved in the binder and thus greatly decreases the content of
titanium dissolved into the binder. The re-building solubility rule determines the development of phases and
microstructure. (C) 2007 Elsevier B.V. All rights reserved.

摘要: Chemokine CCL21 can effectively attract CCR7(+) dendritic cells (DCs), however its role in this
event is poorly understood. In this report, we investigated the effect of exogenous CCL21 expressed in
breast cancer MCF-7 on human monocyte-derived DCs. CCL21-transfected MCF-7 stimulation prompted

DC functions: migration, antigen-uptake and presentation. The stimulated DCs facilitated Th1 type
cytokines production, perforin-forming CD8(+) T cell transformation and final T cell-associated clearance
of MCF-7. Moreover, the MCF-7-resourced CCL21 protected DCs from apoptosis significantly, involving
up-regulations of Bcl-2 expression and NF-kappa B activity, and reduction of caspase-3. This study
provides evidence that tumor-derived CCL21 increases the presentation and apoptosis resistance of DCs,
suggesting such a mechanism may be useful for the improvement of tumor cell immunogenicity and
antitumor response. (c) 2007 Elsevier GmbH. All rights reserved.

摘要: In this paper, an aperiodic stochastic resonance (ASR) signal processor for communication systems
based on a bistable dynamic mechanism is proposed for detecting base-band binary pulse amplitude
modulation (PAM) signals in communication systems. All parameters in the processor can be adjusted
when needed. The adjustment mechanism is explained from the perspective of the conventional
noise-induced nonlinear signal processing. To demonstrate this processor's usability, a digital
image-watermarking algorithm in the discrete cosine transform (DCT) domain is implemented. In this
algorithm, the watermark and the DCT alternating current (ac) coefficients of the image are viewed as the
input signal and the channel noise, respectively. In conventional watermarking systems, it is difficult to

explain why the detection bit error ratio (BER) of a watermarking system suffering from certain attacks is
lower than that of the system not suffering from any attack. In the new watermarking algorithm, this
phenomenon is systematically analyzed. It is shown that the DCT ac coefficients of an image as well as the
noise imposed by the attacks can cooperate within the bistable system to improve the performance of the
watermark detection. (C) 2008 Elsevier B.V. All rights reserved.

摘要: This paper is concerned with the adaptive robust convergence for a class of neural networks with
time-varying delays. By employing the Lyapunov method and a novel lemma, some delay-independent
conditions are derived to guarantee the state variables of the discussed time-varying robust system to
converge, globally, uniformly, exponentially to a ball in the state space with a pre-specified convergence
rate. Here, the existence and uniqueness of the equilibrium point needs not to be considered. Finally. ail
illustrated example is given to show the effectiveness and usefulness of the results. (C) 2007 Elsevier Ltd.

摘要: The first principle method was applied to Study the electronic structure and magnetic properties of
the compound of Cu(HCO2)(NO3)(pyz). The density of states, the electronic structure and the spin
magnetic moments are calculated. The results reveal that the compound has a ferromagnetic interaction
arising from the bridging mu-HCO2 and pyz ligands, and the ferromagnetic properties come from the spin
delocalization effect. The spin magnetic moment 1.0 mu(B) per molecule mainly comes from the Cu ion,
but has little contribution from O, N and C anion. (C) 2008 Elsevier Ltd. All rights reserved.

标题: The landslides in the Three Gorges Reservoir Region, China and the effects of water storage and rain
on their stability

摘要: According to the statistics, there were about 1,736 landslides with the total volume of 1.339 x 10(11)
m(3) in the 100 km(2) area of upper reaches of the Yangtze River, in which about 94% of landslides are
triggered by rain and water storage. Thus, based investigation of the results of the landslides in this region,
this paper completed a systematic study on the effects of rainfall and water storage on the landslides in the
region and found that the distribution of landslides over time and space are well correlated with the
precipitation distribution in this region; landslides are also strictly controlled by the stratum, geological
structure, river valley form, shore type, etc. Meanwhile, the pattern of water table variation of the three
gorges reservoir will do have very serious impacts on the stability of the slopes in this region. All research
results show that water storage and rainfall are the two important inducing factors that can cause a lot of
large-scale landslides. Therefore, some effective control measures for water storage and rainfall should be
taken so as to minimize the impacts of water on the stability of the slopes in the Three Gorges Reservoir
Region of Yangtze River, China.

摘要: Human leukocyte antigen G (HLA-G) is one of the molecules implicated in immunotolerance. To
investigate the role of HLA-G in primary cutaneous malignant melanoma (CMM), a series of 47 skin
melanocytic lesions were immunohistochemically evaluated. The correlation between HLA-G expression
and CMM clinicohistopathological data and Bcl-2 expression was also analyzed. HLA-G expression was

detected in a variety of cell types. No significant difference in HLA-G expression was observed between
malignant and non-malignant melanocytic lesions. HLA-G expression was significantly correlated with the
inflammatory infiltration and Bcl-2 expression, whereas no significant correlation with ulceration, tumor
thickness, clinical stage, histopathological subtypes were observed. HLA-G expression may be the result of
host immune reaction in tumor microenvironment rather than a malignant feature of CMM.

摘要: This Letter deals with the problem of delay-dependent robust exponential stability in mean square for
a class of uncertain stochastic Hopfield neural networks with discrete and distributed time-varying delays.
Based on Lyapunov-Krasovskii functional and the stochastic stability theory, delay-dependent stability
criteria are obtained in terms of linear matrix inequalities (LMIs). Because of introducing some
free-weighting matrices to develop the stability criteria, the proposed stability conditions have less
conservatism. Numerical examples are given to illustrate the effectiveness of our results. (c) 2008 Elsevier

摘要: Silica gel-supported Fe(II) (SiOFe) was prepared and used for heterogeneous degradation of
sulforhodamine B (SRB) and 2,4-dichlorophenol (DCP) under visible irradiation ('lambda > 420 nm) as an
effective catalyst. UV-visible spectra, and infrared Spectrophotometry (IR), fluorescence, total organic
carbon (TOC) and electron spin resonance (ESR) measurements were employed to analyze the
photoreaction products. The results showed that SRB could be efficiently degraded by SiOFe/H2O2 system
under visible irradiation with 100% decolorization and 72.3% TOC removal after 180 min illumination.
The results of ESR and fluorescence measurements indicated that the oxidative process was predominated
mainly by the hydroxyl radical (OH) generated in the system.

摘要: A displacement approach was developed for the, competitive binding studies. The binding reaction of
non-steroidal anti-inflammatory drugs (NSAIDs), indomethacin, sulindac and their metal complexes with
BSA were studied by using Eosin Y ( 2, 4, 5, 7-tetrabromofluorescein) as the potentiontric probe. It was
Showed that the addition of drug could displace Eosin Y which bound to BSA with electrostatic forces, and
the absorbance of eosin Y changed toward free from eosin Y BSA complex. The competitive binding
approach was used to access and compare quantitatively the displacing ability of the various drugs. The
results indicated that Cu (II) complex of indomethacin or sulidac showed more potential binding activity.

摘要: A water-soluble polysaccharide named as HPS-1 was isolated from the roots of Hedysarum
polybotrys Hand.-Mazz by hot water extraction, anion-exchange and gel-permeation chromatography and
tested for its anti-tumor activity. Its structural characteristics were investigated by FTIR, HPLC, NMR
spectroscopy, GLC-MS, methylation analysis, periodate oxidation and Smith degradation. Based on the
data obtained, HPS-1 was found to be an alpha-(1 -> 4)-D-glucan, with a single alpha-D-glucose at the C-6
position every nine residue, on average, along the main chain. The glucan has a weight-average molecular
weight of about 9.4 x 10(4) Da. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT)
assay revealed that HPS-1 significantly inhibited the proliferation of human hepatocellular carcinoma
HEP-G2 cells and human gastric cancer MGC-803 cells in vitro, indicating HPS-1 could have a possible
cancer therapeutic potential. (C) 2008 Elsevier Ltd. All rights reserved.

between o-phenylenediamine (OPDA) and hydrogen peroxide in the buffer medium of NaAc-HAc at pH
4.48 to form a new product 2,3-diaminophenazine (DAPN). Then the fluorescence intensity of DAPN is
measured and 426 and 554 nm are chosen as the excitation and emission wavelengths. Therefore, with the
foreknown concentration of input hydrogen peroxide, a series of fluorescence intensities of DAPN are
acquired according to a series of different concentration of hydrogen peroxide as input, greatly improving
the selectivity and sensibility of the system. A relationship between the input concentration of hydrogen
peroxide and the fluorescence intensity of DAPN is then obtained using a linear regression. Results show
that fluorescence intensity of DAPN is in proportion to the increase in the concentration of hydrogen
peroxide in the range of 9.0 x 10(-7)-3.56 x 10(-5) mol . L-1 almost linearly. The linear equation is
F==1.15c (mu mol . L-1) + 398. 6 (r = 0.9991) and the detection limit is 2.7 x 10(-7) mol . L-1 (n=11). The
relative standard deviation of 11 parallel measurements with the concentration of H2O2 at 7.5 x 10(-6) and
3.0 x 10(-5) mol . L-1, is 2.2 and 1.0%, respectively. Results from DPD method was used to verify this
method. The interference of foreign iron was studied. Compared to the traditional methods, this binary
system has a simplified operation and high sensitivity. The proposed method has been successfully applied
to determine the concentration of hydrogen peroxide in rainwater.

摘要: We find that a collective flow model can successfully be used to analyze charged particle
distributions at AGS and lower SPS (E-NN(lab) less than 20 GeV in the laboratory frame) but fails at RHIC.
The tail of the distribution of charged particles at RHIC has a jump from the collective flow model
calculation as the energy increases. In this paper a thermalization component model is presented based on
collective flow to study the multiplicity distributions at RHIC. It is realized that the region of phase space
of collective flow can reflect that of the thermalization region. By comparing the contributions of particle
production from the thermalization region at different energies and different centralities, we can deepen our
study on collective movement at RHIC.

摘要: The panchromatic (Pan) sharpening of multispectral (MS) bands is an important technique in the
various applications of satellite remote sensing. This paper presents an MS Pan-sharpening method using
the proposed multiscale mapped least-squares support vector machine (LS-SVM). Under the LS-SVM
framework, the salient features underlying the image are represented by support values, and the support
value transform (SVT) is developed for image information extraction. The low-resolution MS bands are
resampled to the fine scale of the Pan image and sharpened by injecting the detailed features extracted from
the high-resolution Pan image. The support value analysis is implemented by using a series of multiscale
support value filters that are deduced from the mapped LS-SVM with multiscale Gaussian radial basis
function kernels. Experiments are carried out on very high resolution QuickBird MS + Pan data. Fusion
simulations on spatially degraded data, whose original MS bands are available for reference, show that the
proposed MS Pan-sharpening method performs comparable to the state-of-the-art in terms of the pertained
quantitative quality evaluation indexes, such as the Spectral Angle Mapper, relative dimensionless global
error in synthesis (ERGAS), modulation-transfer-function-based tool and quality index (Q4), etc. The SVT
is an effective tool for remote sensing image fusion.

摘要: The alternate-direction implicit finite difference beam propagation method (FD-BPM) is used to
analyze the two-dimensional (2D) symmetrical multimode interference (MMI) couplers. The positions of
the images at the output plane and the length of multimode waveguide are accurately determined
numerically. In order to reduce calculation time, the parallel processing of the arithmetic is implemented by
the message passing interface and the simulation is accomplished by eight personal computers.

摘要: A 3-D elastic finite element model was developed to investigate the stresses distribution of
bi-adhesive bonded joints (i.e., the bond line of joints filled with two adhesives of dissimilar toughness).
The effects of the loading mode on the stress distribution of joints, including the single-lap joints under
tensile loading (i.e., single-lap joints) and the butt joints under cleavage loading (i.e., cleavage joints), were
also studied in detail. Results showed that higher stress, distributed at the contact position of the dissimilar
adhesives placed along the bond line of bi-adhesive bonded joints. Also, the maximum stress of the
adhesive layer decreased when the length ratios and bonding sequence along the bond line, filled with two
dissimilar adhesives, was appropriately designed. At the same time, stress convergence in the adhesive
layer of bi-adhesive joints was also obviously reduced in contrast to the mono-adhesive joints. The

numerical investigation shows that it is necessary to take into account the change of loading modes when
optimizing the bi-adhesive joint design, because of the uneven and complex loading modes of the adhesive
bonding structure in the engineering applications.

摘要: A pair of flavanone glucoside diastereomers, (2R)- and (2S)-eriodictyol-5-O-beta-D-glucopyranoside
(1a, 1b), was successfully separated by RP-C18 high-performance liquid chromatography from
Balanophora involucrata Hook. f. Some other compounds, including a pair of flavanone enantiomers, (2R)and (2S)-eriodictyol (2a, 2b), and a pair of flavanone glucoside diastereomers, (2R)- and
(2S)-eriodictyol-7-O-beta-D-glucopyranoside(3a, 3b), were separated by capillary electrophoresis from the
same plant. The absolute configurations at C-2 of la and 1b were determined based on their circular
dichroism spectra. Enzymatic hydrolysis of 1a and 1b by beta-D-glucosidase afforded (2R)- and
(2S)-eriodictyol, respectively, which were used as the authentic standards for co-elution to determine the
migration order of the enantiomers, 2a and 2b. We also report the first example of identifying the migration
order of 2a and 2b and resolving the separation of 3a and 3b by capillary electrophoresis. In addition, la
was unambiguously characterized for the first time by NMR spectra. (C) 2008 Elsevier B.V. All rights

摘要: BACKGROUND: Many investigators have indicated that overexpression and amplification of the
human protooncogene c-erbB-2 is an independent prognostic factor for primary tumors. We studied
expression of c-erbB-2 protein in tissues from extrahepatic cholangiocarcinoma, tissues peripheral to the
carcinoma and normal bile ducts, and discussed the occurrence and development of extrahepatic
cholangiocarcinoma. Another aim was to explore possible application of the c-erbB-2 gene for clinical
diagnosis, pathological differentiation and treatment of extrahepatic cholangiocarcinomas.
METHODS: The c-erbB-2 expression levels from 75 samples of extrahepatic cholangiocarcinoma, 48
samples of tissues peripheral to the carcinoma and 9 samples from normal bile ducts were assayed by
immunohistochemical streptavidinbiotin complex (SABC).
RESULTS: The rates of c-erbB-2 expression in extrahepatic cholangiocarcinomas, tissues peripheral to the
carcinomas, and normal bile ducts were 80% (60/75), 56% (27/48), and 0% (0/9), respectively. In the
extrahepatic cholangiocarcinomas, the expression of c-erbB-2 was directly proportional to the malignant
grade and tumor metastasis. The expression rate of c-erbB-2 in tumors with nerve infiltration was
significantly higher than in those without nerve infiltration. The expression rates of c-erbB-2 in tumors with
histological grade III/IV were significantly higher than in those with histological grade I. The expression of
c-erbB-2 was not correlated with the size or position of tumors, blood vessel infiltration or patients' sex or
age.
CONCLUSIONS: c-erbB-2 was only expressed in extrahepatic cholangiocarcinomas and tissues peripheral
to the carcinomas but not in normal bile ducts, indicating that c-erbB-2 may play an important role in the
occurrence and development of extrahepatic cholangiocarcinoma. The fact that the expression level of
c-erbB-2 was highly correlated with differentiation grade and metastasis of the tumor suggests potential
clinical importance of c-erbB-2 as a tumor biomarker in the diagnosis, treatment and prognosis of
extrahepatic cholangiocarcinoma.

摘要: The brevidensovirus is one of the smallest viruses in the world and the capsid of Aedes albopictus
C6/36 cell densovirus (C6/36DNV) is the simplest and most compact capsid in brevidensovirus. To
understand the assembly mechanism of icosahedral-virus capsid from this simplest model, we tried to
express various lengths of virus proteins (VPs) of C6/36DNV in Bac-to-Bac((R)) system and evaluate their
self-assembly capacities in insect Spodoptera frugiperda 9 (Sf9) cells. The result showed that the
N-terminal GGSG sequence (residue 23-26), highly conserved glycine-rich region in Parvoviridae, and
C-terminal GTGGVVTCMP (residue 344-353) were essential for capsid assembly, while the N-terminal
nuclear localization signal, GTKRKR sequence (residue 15-20), was nonessential for the virus-like
particles (VLPs) assembly, but did effect the formation of crystalline arrays in infected Sf9 cells. These
information provided clues for how icosahedral-virus capsids formed and showed the potential of
C6/36DNV-VLPs becoming a powerful nanoparticle vector. (c) 2007 Elsevier B.V. All rights reserved.

摘要: The discrete-time uncertain nonlinear models are considered in a Takagi-Sugeno form and their
stabilization is studied through a nonquadratic Lyapunov function. The classical conditions consider a
one-sample variation, here, the main results are obtained considering k samples variation, i.e., Delta
V-k(x(t)) = V(x(t + k)) - V(x(t)). The results are shown to always include the classical cases, and several
examples illustrate the effectiveness of the approach.

摘要: The paper discusses the stability of non-autonomous bidirectional associative memory neural
networks. The existence and uniqueness of periodic solutions of the neural networks are investigated by
using Gaines and Mawhin's continuation theorem of coincidence degree theory in the paper. Moreover,
criterions on asymptotic stability and exponential stability of periodic solutions of the neural networks are
obtained by using matrix function inequality, and algorithms for the criterions on the neural networks are
provided. Some of the results in the paper generalize and improve the results in the existing references. In
the end, an illustrate example is given to verify our results. (c) 2007 Elsevier B.V. All rights reserved.

摘要: As a potential artificial cartilage material, the friction and wear properties of nano-hydroxy apatite
(HA) particles filled poly (vinyl alcohol) hydrogel (PVA-H) composites sliding against stainless steel disk
under water lubrication condition were studied by using a four ball tester. The worn surfaces were
investigated by using a scanning electron microscope (SEM) to determine the wear mechanisms.
Experimental results show that filling HA to PVA-H will slightly increase the friction coefficient of
composites with the increasing of HA content under water lubrication condition. Meanwhile, HA particles
can greatly reduce the wear mass loss of the PVA-H composites and enhance the load carrying capacity, the
wear loss of the 1 wt% HA reinforced PVA-H composites can be decreased by 30 percent under 2.0 MPa to
50 percent under 0.5 MPa contact pressure. We also found that 2 wt% HA content of composites increase
the wear mass loss under the same condition. SEM examination shows that the worn surface of low HA
containing (1 wt%) composites are much smoother than that of pure PVA-H or high HA containing (2 wt%)
composites under 1.5 MPa contact pressure. It is also found that there are big hole and big reunited HA
particles in the surface of 2 wt% HA containing composites, which leads to deterioration of the surface of
samples under higher loads in water lubrication. These results may be useful in the tribological design of
artificial articular cartilage material.

摘要: The effects of direct current (dc) bias-drifting on radio on fiber (RoF) links are quantitative
investigated and simulated. Single sideband (SSB) modulation and carrier suppressed double sideband
(CS-DSB) modulation RoF links are considered, power variation of targeted signal and harmonic
suppression on account for bias-drifting are calculated and evaluated. Our results suggest that power
variation can be maintained within 1.1 dB with dc bias drift epsilon less than 5% in the SSB modulation
RoF link and the degradation of harmonic suppression is evident with epsilon exceed 2% in the CS-DSB
modulation RoF link.

摘要: A microcalorimetric technique based on the bacterial heat output was explored to evaluate the effect
of copper-indomethacin complex on Staphylococcus aureus and Escherichia coli. The extent and duration
of the inhibitory effect on the metabolism as judged from the rate constant (k) in log phase, half inhibitory
ratio (IC50). The rate constant of bacteria in the presence of the drugs decreased with increasing
concentrations of the drugs. The copper complex exhibited higher antibacterial activity than the parent drug
whose IC50 value was 1.5 and 2.3 times lower than that of indomethacin to S. aureus and E. coli,
respectively. It was indicated that when the copper ion is coupled with indomethacin, the drug is more
potent as a bacteriostatic.

摘要: This paper is concerned with the Holling-Tanner prey-predator model subject to the homogeneous
Neumann boundary condition. We will show that under certain hypotheses, even though the unique positive
constant steady state is uniformly asymptotically stable for the dynamics with diffusion, non-constant
positive steady states can exist due to the emergence of cross-diffusion. The biological implication of
cross-diffusion means that the prey species exercise a self-defense mechanism to protect themselves from
the attack of the predator. Our result also demonstrates that cross-diffusion can create Stationary Patterns.

real practical control process. Therefore, it is of critical importance but a great challenge and still at its early
age to design a stable and robust controller for such a process. In the proposed research, dynamic neural
networks were constructed to precisely approximate the non-linear system with unknown uncertainties first,
a non-linear state feedback H-infinity control law was designed next, then an adaptive weighting
adjustment mechanism for dynamic neural networks was developed to achieve H-infinity regulation
performance, and last a recurrent neural network was employed as a neuro-solver to efficiently and
numerically solve the standard LMI problem so as to obtain the appropriate control gains. Finally, case
studies further verify the feasibility and efficiency of the proposed research.

摘要: An approach to polygonal approximation of regular digital curves based on PSO algorithm is
presented. In this paper, each particle corresponds to a candidate solution to the polygonal approximation
problem, which is represented as a binary vector. The offset error of centroid between the original curve
and the approximation polygon, and the variance of distance error for each approximation segment are
adopted in the fitness function to evaluate the feasibility degree of the candidate solution. The sigmoid
function of iteration times is used as the acceleration factors instead of the constant factors to improve the
global searching characteristics. Experimental results show that the proposed approach can get suitable
approximation results for preserving the features of original curves.

scale-free network, the time to reach a consensus is hundreds of times shorter than that of the
nearest-neighbor coupled network with the same average degree and network size, and its robustness to the
node-failure and edge-failure is increased at the same time. Furthermore, as the scale-free network becomes
more homogenous, or its average degree becomes larger, the time to reach a consensus will become shorter,
but not notably shorter. Therefore, the scale-free network with a larger exponent r and average degree k is a
better choice to obtain a faster convergence speed in the consensus problem.

标题: Screening of QHF formula for effective ingredients from Chinese herbs and its anti-hepatic cell
cancer effect in combination with chemotherapy

摘要: Background Recent studies have shown that effective ingredients of Chinese herbs are used more and
more widely in the treatment or co-treatment of cancers, however, they are usually used separately and
there has been limited research about joint application of Chinese herbs in multi-modal treatment. The aim
of this study was to screen a QHF (Q: Qingrejiedu, H: Huoxuehuayu and F: Fuzhengguben) formula for
effective ingredients from Chinese medicines and assess its anti-hepatic cell cancer (HCC) effect in
combination with chemotherapy.
Methods Six effective ingredients from Chinese medicine were selected based on the previous literature
and used in the study. The QHF formula and the best ratio of ingredients were evaluated in H-22 mouse
(KM) models with solid tumors and ascites tumors by uniform design and monitoring inhibition of tumor
growth and survival. We then observed the anti-hepatic cell cancer (HCC) effect of QHF when combined
with cisplatin (DDP) in H-22 mouse (Balb/c) models with solid tumors and ascites tumors. Evaluating of
the therapeutic effect included the general condition of the mice, inhibition of tumor growth, survival,
changes in body weight, thymus index, spleen index and WBC counts.
Results The optimal QHF dose ratio for anti-hepatic cell cancer treatment was: 800 mg/kg Cinobufotalin,
14 mg/kg Ginsenosides Rg3, 5.5 mg/kg PNS and 100 mg/kg Lentinan. Treatment was more efficient in
inhibiting the growth of transplanted tumors in H-22 mice when using the QHF formula (55.91 %) than
using Cinobufotalin (33.25%), Ginsenosides Rg3 (35.11 %), PNS (27.12%) or Lentinan (4.97%) separately.
QH F also prolonged the life of H22 ascites hepatic cancer mice more efficiently (38.13%) than
Cinobufotalin (25.00%), Ginsenosides Rg3 (27.27%), PNS (23.30%) or Lentinan (24.43%). QHF
combined with DDP could reduce DDP-induced leucopenia, spleen and thymus atrophy and other toxic
reactions. Combining QHF with DDP the tumor growth inhibition reached 82.54% with a 66.83% increase
in survival.

Conclusions QHF is more efficient in anti-hepatic cell caner treatment than the single drugs that constitute
the formula. QHF combined with DDP can attenuate tumor growth and suppresses the DDP-induced toxic
reactions.

摘要: A physical model is proposed to study the laser-induced plasma dynamics expansion during
irradiation of material by a high-intensity nanosecond pulsed laser beam. Based on a consideration of the
plasma ionization effect and local conservations of mass, momentum and energy, combined with the
assumption that plasma can be viewed as a compressible ideal fluid and a high temperature-high pressure
ideal gas, we developed a new dynamics expansion mechanism for plasma produced by pulsed laser
radiation. A set of new plasma expansion dynamics equations based on our model are first deduced. Then,
taking the example of the carbon target, using the finite difference method, the plasma flow dynamics into a
vacuum, such as plasma spacial number density distribution, plasma number density and velocity
evolvement in radial and axial directions, are studied in detail. The results show that there are some main
factors affecting the velocity distribution of the plasma, including the temperature of the plasma, the
ionization fraction of the plasma and the dynamic source provided by the vaporized material. The velocity
u(z) in the longitudinal direction is different from u(r) in the transverse direction because of huge initial
eject velocity and evaporated dynamic source. The velocities of the plasma calculated by this model are
found to be in better agreement with the experimental results derived from the work of Sanz et al ( 1985
Plasma Phys. Control. Fusion 27 329) compared with the conventional model.

摘要: A modified sol-gel method was used to fabricate (Pb0.25BaxSr0.75-x)TiO3 (PBST) thin films with
x=0.05,0.1,0.15 and 0.2 on Pt/TiO2/SiO2/Si substrate. The structure, surface morphology, dielectric and
tunable properties of PBST thin films were investigated as a function of barium content (x). X-ray
diffraction and scanning electron microscopy analysis showed that we could get pure PBST perovskite
phase and relative fine density thin films with smooth surface. It was found that the crystal lattice constant,
grain size, room temperature dielectric constant, dielectric loss and tunability of Ba solutionizing PST thin
films increased with the increase in Ba content. For (Pb0.25Ba0.2Sr0.55)TiO3 thin film, it had the highest
dielectric constant of 1390 and the largest tunability of 80.6%. The figure of merit parameter reached a
maximal value of 28.9 corresponding to the (Pb0.25Ba0.05Sr0.7)TiO3 thin film, whose dielectric constant,
dielectric loss and tunability measured at 1 MHz were 627, 0.024 and 69.4%, respectively. (C) 2007

摘要: Hydroxyapatite (HA) was incorporated into polyvinyl alcohol hydrogel (PVA-H) to form a bioactive
composite for applications as artificial cartilage. HA/PVA-H composite containing 2 and 5 wt.% of HA was
made for in vitro evaluation. Immersion tests in vitro were performed with PVA-H and HA/PVA-H
specimens. XRD, FTIR and SEM were used to characterize the structure and component of specimens.
SEM results showed that apatite formed within a short period on HA/PVA-H composite after its immersion
in SBF, demonstrating high in vitro bioactivity of the composite. Characteristic peaks Of PO43- were
enhanced, and new peaks Of CO32- were found after immersion on the FTIR experiments. These results
proved that the crystalloid deposition on the surface of HA/PVA-H were bone-like apatite. It also found that
the precipitation of apatite increased with increase in HA content of the composites, as well as with
increasing immersion time for the composite. Mechanical study revealed that the elastic modulus of
HA/PVA-H composite increased initially with immersion time in SBF, due to apatite formation on
composite surface and kept constant after prolonged immersion in SBF. (c) 2007 Elsevier B.V. All rights

摘要: The dynamics expansion mechanisms for plasma plume generated by pulsed laser radiation are
studied in detail, taking account of plasma ionization effect. Based on the consideration of local
conservations of mass, momentum, collected as the assumption that plasma can be viewed as compressible
ideal fluid and high temperature-high pressure ideal gas, we develop a new dynamics expansion mechanism
for plasma produced by pulsed laser radiation. Using the analytical method, the space number density and
pressure evolvement of plasma in cylindrical coordinate are obtained, the dynamics evolvement equations
are also derived. The results from the present model indicate that the plasma dynamic expansion behaviour
can be evidently influenced by the ionization fraction.. Its effect is similar to a new dynamic source for
plasma expansion and increases the expansion acceleration in all directions. The predictions of the
expansion of the plasma is affected by the temperature, the average atoms mass and the ionization degree of
the plasma are consistent with the experimental results.

摘要: Silicon/Silver composite with nano-sized silver particles was synthesized based on principle of a
disturbed silver-mirror reaction. Comparing with the direct method, highly dispersed nano-silver particles
are easier to be obtained by the present method with simple preparation technology and high productivity
of silver. Silver particles with particle size less than 20 nm were uniformly dispersed on the surface of
silicon particles, no any other phase except silicon and silver could be observed in the composite. The
composite with 10wt% of silver could deliver a reversible capacity more than 500 mAh.g(-1) after 30
cycles. AC impedance spectra indicate that existence of nano-silver is favorable to electrical conductivity;
therefore, cycleability of composite is improved.

作者关键词: nano-composite Ti(C, N)-based cermet; cutting; wear mechanism; adhesive wear
摘要: Nanocomposite Ti(C, N)-based cermet tools were prepared by vacuum sintering and tested in turning
quenched medium carbon steel at various combinations of cutting speed (V-c), feed rate (f), and depth of
cut (a(p)). The wear mechanism was investigated in detail using scanning electron microscopy (SEM) and
electron-probe microanalysis (EPMA). It was found that, the newly fabricated cermet tools exhibited higher
wear resistance and better cutting performance when cutting quenched medium carbon steel. And extrusion
deformation of the tool in compression strain and adhesive wear were the main source of cermet tools
failure, and meanwhile diffusion and oxidation were also observed.

摘要: A novel, fast unblocking scheme for distance protection to identify symmetrical faults occurring
during power swings has been proposed in this paper. First of all, the change rate of three-phase active
power and reactive power being the cosine function and the sine function with respect to the phase
difference between the two power systems during power swings has been demonstrated. In this case, they
cannot be lower than the threshold of 0.7 after they are normalized. However, they will level off to 0 when
a three-phase fault occurs during power swings. Thereafter, the cross-blocking scheme is conceived on the
basis of this analysis. By virtue of the algorithm based on instantaneous electrical quantities, the calculation
of the active and reactive power is immune to the variation of the system power frequency. As the
integration-based criterion, it has high stability. Finally, simulation results show that this scheme is of high
reliability and fast time response. The longest time delay is up to 30 ms.

摘要: TiO2 nanoparticles doped with different content of nitrogen were prepared by sol-gel method, and
preliminarily characterized by means of XRD, TEM and UV-vis spectra. The concentration of nitrogen of
N/TiO2 was detected using XPS and elemental analyzer method (EA). It was Confirmed by XPS that
oxygen sites were substituted by nitrogen atoms and Ti3+ species was formed on the surface of the
nitrogen-doped titania; UV-visible reflectance spectra measured the band gap (E-g) of nitrogen-doped
titania in different content, which indicated that an N-induced midgap level was formed from above the

valence band (O 2p). The Eg of N/TiO2 could be estimated to be 2.50 eV when the molar ratio of N to Ti
was 0.0880, which was narrowest. The photocatalytic degradation of sulforhodamine-B (SRB) and
4-chlorophenol (4-CP) in aqueous solution was used as probe reactions to evaluate their photocatalytic
activity with different doped content. It indicated that the N/TiO2 Powder with molar ratio
n(N)/n(Ti)=0.0880 exhibited highly catalytic activity for degradation of SRB under visible light irradiation.
The formed oxidation species, total organic carbon (TOC), chemical oxygen demand (CODCr) and infrared
spectrophotometry (IR) assays showed that the mechanism of photocatalytic degradation involved the
excitation of electrons from the isolated N 2p orbitals to the Ti 3d orbitals, generating center dot OH for
degradation of organic compounds.

摘要: The influence of the height and angle of the inner chamfer near the unload ends of the adherends and
the elastic modulus of several adhesives on the stress distribution in the single lap joint has been
investigated using both the elasto-plastic finite element analysis (FEA) and experimental methods. The
results from FEA show that the peak stress in the mid-bondline decreases enormously as the adherends are
chamfered with an angle of 30 degrees and a chamfer height through full thickness on the inner side of the
adherend. When the chamfer angle and the charnfer height are taken to be constant (h = H and 0 = 30
degrees), the peak stresses in the fillet near the ends of the adherends decrease gradually as the elastic
modulus of adhesives increases while all the peak stresses in the middle part of the overlap increase
enormously except in the case of the peel stress. It is certain that the load-bearing capacities of the joints
are better with a charnfer height of H and a charnfer angle of 30 degrees. The results obtained from the
numerical modeling were in compliance with the experimental tests. (c) 2007 Elsevier Ltd. All rights

摘要: A 40 Gbit/s hybrid optical code-division multiplexing (OCDM)/wavelength-division multiplexing
(WDM) system is experimentally demonstrated and simultaneous multiwavelength optical encoding of a
single supercontinuum source using superstructured fiber Bragg grating is achieved. The interchannel
interference and noise of the OCDM/WDM system is suppressed apparently by incorporating a nonlinear
amplifying loop mirror, both the sidelobe and the pedestal are reduced, the waveform quality of decoded
signal is improved, and the original 8.2 ps auto-correlation peak of decoded pulse is compressed to 4.8 ps.

摘要: In this study, a novel procedure is presented for control and analysis of multiple autonomous agents
with point mass dynamics achieving flocking motion with a time variant leader. Two control laws are
proposed for a group of autonomous agents to achieve flocking formations related to two different centers
(mass center and geometric center) of the flock. The first one is designed for flocking motion based on
mass center and the second for geometric center. Distance-dependent adjacency matrix is used to quantify
the way agents influence each other. Theoretical analysis is established to indicate the stability
(cohesiveness, collision avoidance and velocity matching) of the control systems using classical Lyapunov
theory. Finally, a simulation example is demonstrated to validate the theoretical results.

摘要: We investigate 114 online auction systems by searching in main search engines (Baidu and Google)
with keywords "online auction" and "Internet auction" (in Chinese). First we perform an analysis of the
three main business models and point out that "Doing-well" websites have nine features. Second, we
compare the auction frequencies of different websites and find that most auctions last about I week. Third,
we look through the closing and bumping rules of online auctions. At last, the popular auction types
adopted in the websites are discussed.

摘要: Current fair electronic cash schemes are mostly based on discrete logarithm problem on finite, which
are not efficient for newly applications on mobile electronic payment since of time cost and storage
requirement of exponentiations. In this paper, we propose a blind signature scheme based on Elliptic Curve
Discrete Logarithm Problem (ECDLP). Compared with typical restrictive blind signature schemes, our
scheme is more restrictive and efficient. A withdrawal protocol and a payment protocol of electronic
payment schemes based on the proposed signature technique are illustrated, which are proved secure.
Comparing with recent similar research schemes based on ECDLP, our scheme has 30% reduction in the
storage requirement of e-cash, and simplifies protocol flows by cancelling the third trusted party.

摘要: This paper researches on the decision-making model of petroleum-gas exploration projects. It builds
a trap evaluation criterion of some basin in West China based both on the actual situation and expert
investigation results. And it gives two improvement methods, optimization model of compatibility degree
maximization and optimization model of compatibility degree maximization & difference degree minimal,
which are designed to evaluate potential of petroleum prospecting based on Compatibility Degree and
Difference Degree. And it also builds an improvement system based both on four traditional methods and
on the two new ones. The compatibility degree and difference degree of all six trap evaluation schemes in
this basin in West China shows us that the trap evaluation schemes by optimization model of compatibility
degree maximization and optimization model of compatibility degree maximization & difference degree
minimal are the best trap evaluation methods, the secondary is the one by the method of probability of
geological success, and the last one is by the method of effectiveness rating. This system is successfully
applied in this basin in West China.

摘要: In a construction project where duration truly equals money, the management of duration is critical,
thus predicting the likelihood of duration may play a key role towards project success. Project managers
should know the completion probability in order to take the necessary corrective actions. On the basis of
the researches of other scholars, this paper analyzed the traditional probability analysis method for duration
risk in PERT and its existing problems. Aiming at the existing problems, it put forward improved
probability analysis method. The result shows that the improved method is convenient, effective and
efficient. It provides scientific basis for project decision-making and supports the decider powerfully.

摘要: In recent three decades, several variants of the hypercube networks have been proposed to enhance
their performance and reliability. The so called enhanced hypercube networks (denoted by Q(n,k)) is one of
these variations. In this paper, the structural natures Of Q(n,k) are investigated in detail. Based on the
analysis of the properties and the performance Of Q(n,k), it is shown that Q,,k has the minimum
transmission delay of k-1+ [n-k+1/2]. The one-to-one routing process is also concerned, and it is proved
that there exist n + 1 internally-disjoint paths between any two distinct nodes in Q(n,k). Finally, The
connectivity and edge-connectivity Of Q(n,k) are found to be n + 1.

摘要: Mehrotra-type predictor-corrector algorithms are the basis of interior point methods software
packages. Salahi et al. in their recent work have shown a feasible version of a variation of Mehrotra's
second order algorithm for linear optimization may be forced to make many small steps that motivated
them to introduce certain safeguards, what allowed them to prove polynomial iteration complexity while
keeping its practice efficiency. In this paper, we extend their algorithm to monotone linear complementarity
problems. Our algorithm is different from their method in the way of updating the barrier parameter and the
complexity analysis, and we also show that the Polynomial complexity Of out algorithm is O(n(2) log
(x(0))(T)s(0) / E).

摘要: A hybrid approach for the surface segmentation of sparse triangle meshes is presented. The algorithm
realizes the segmentation of different regions of triangle meshes through twice segmentations phases: in the
first phase, for sparse mesh regions, the edge-based method is used after combination of planes according
to the variance of the dihedral angle of normal vector; in the second phase, for other surfaces, the
vertex-based method is used to calculate approximate curvature of every triangle mesh according to the
evaluated curvature of vertices, and then to realize segmentation through region growing method.
Satisfactory results have been achieved for sparse meshes of mechanical CAD models.

摘要: In this study, a novel procedure is presented for control and analysis of multiple autonomous agents
with point mass dynamics achieving flocking motion. Two control laws are proposed for a group of
autonomous agents to achieve flocking formations related to two different centers (mass center and
geometric center) of the flock. The first one is designed for flocking motion based on mass center and the
second for geometric center. Distance-dependent adjacency matrix is used to quantify the way agents
influence each other. Theoretical analysis is established to indicate the stability (cohesiveness, collision
avoidance and velocity matching) of the control systems using classical Lyapunov theory. Finally, a
simulation example is demonstrated to validate (he theoretical results.

摘要: With the application of Chaos and Nonlinearity technology in analyzing the water quality pollution in
water conservancy establishment, the result of the experiment at GeZhou Dam ship lock indicates that the
water difference within the affected 12kms is confined within 1.5meters during 24hours a day, the peak
hours are the 11(th), 16(th), 20(th) and 22(nd) hour of the day. The concentration of Physical-chemicals and
COD, TP, NH3 vary greatly at different areas of the water. The high concentration areas are far away from
the source, and the quality of the water has no direct relation with the hydrology parameter (low abundant
even). The system has the effect of mutation, restriction, openness, self-Chaos and Nonlinearity. The Water
Quality Pollution Nonlinearity Dynamic Model, which is based on the application of Dissipation Structure
Theory, was proved to have controlled the error rate within 3% to 6%.

摘要: This paper presents a new primal-dual interior-point algorithm with reduced potential function for a
class of convex programming, based on the ideas of that method for solving linear programming. The new
algorithm chooses the classical Newton direction as iteration direction and its iteration stepsize is
determined by potential function. As the search directions Delta x and Delta s aren't orthogonal any more,
the complexity analysis of this method is different from that of linear programming, correspondingly.
Under a scaled Lipschitz condition, the algorithm is proved to possess O(nL) iteration-complexity bounds.

摘要: Natural feature backing is a very important research topic in computer vision field and has been used
widely in Augmented Reality (AR). This paper gives a robust points tracking or transferring method based
on the Euclidean reconstruction technique for AR systems. The points to be tracked include the lost natural
features, and any points that are specified by the users. The proposed method distinguishes itself in
following ways: Firstly, it is stable as it remains effective even when the camera is moved rapidly. Secondly,
the proposed method is robust because it can operate normally as long as at least four pairs of reference
point correspondences can be found during the augmentation process. Thirdly, we propose an augmented
optical flow method by which the registration, annotation and video augmentation can still work even
under the circumstances of large changes in illumination and viewpoint during the entire process. Several
experiments have been conducted to validate the usability of the proposed approach.

It analyzes image under the least squares support vector machine (LS-SVM) framework and uses the
support values to represent salient features underlying image. The Gaussian filter, used in conventional
level set method to compute the edge indicator, is replaced by the support value filter deduced from the
mapped LS-SVM. The level set evolution method is implemented on the feature image obtained by
convolving the support value filter with the original image. Experiments are undertaken on the synthetic
and real images. The experimental results demonstrate that the support value filter can provide a good
estimate for the optimal step size in a gradient descent algorithm and the proposed method has advantages
over the direct level set evolution method in converging speed and contour extraction accuracy. (C) 2008

摘要: Fair tracing is an important mechanism to prevent or detect crimes in anonymous electronic cash
schemes. Current fair electronic cash schemes are mostly based on discrete logarithm problem on finite,
which are not efficient for new applications on mobile electronic payment owing to time cost and storage
requirement of exponentiations. In this paper, a fair electronic cash system based on Elliptic Curve
Cryptography is proposed. An opening protocol, a withdrawal protocol and a payment protocol of the
electronic cash scheme are illustrated. With a blind signature technique based on Discrete Logarithm
Problem (ECDLP), electronic coins can't be forged without secret key of bank, and customers' privacy is
protected well. But the anonymity of participants can be revoked if the e-coin is spent more than one times.
In comparison with recent similar research schemes based on RSA, our scheme has 30% reduction in the
storage requirement of e-cash.

摘要: This paper illustrated a novel registration method for planar scene based on natural features tracking
via affine transform. Our method can be divided into two stages: offline 3D reconstruction and online
registration. With the obtained feature correspondences, the homographic was computed between the world
plane and the current frame robustly. Then, the registration matrix was synthesized based on the above
homographic and the transform matrix between the plane and world coordinate system obtained in offline
stage. The proposed method also distinguishes itself in two ways: Firstly, a new method was established in
the world coordinate system. Secondly, a novel affine transform based method to match features between
reference images and currently frame directly. The method can avoid the user's intervention in initializing
stage, while overcoming the problem of error accumulation. Some experiments were carried out to
demonstrate the validity of the proposed approach.

摘要: This paper presents a novel image segmentation method based on the integration of level set and
marker methods. The two distinct techniques for image processing are combined in a manner to utilize the
strengths of both. The internal markers obtained by extended-maxima transform bring a priori knowledge
to bear on the image segmentation. The initial level set function is constructed from region of interest (ROI)
on the internal markers. In (his way, an automatic initialization of the level set evolution can be obtained,
and the boundaries of the objects can be extracted. The cost time does not depend on the size of the image
but the region of internal marker because only level set function with markers is updated instead of the
level set function for each pixel. Therefore, the consumed time is greatly reduced. The efficiency and
accuracy of the method are demonstrated by the experiments on the real blood vessel images and MR
image.

摘要: A newly developed probability density evolution method is presented for dynamic response analysis
and reliability assessment of non-linear structures. In the method, a completely uncoupled one-dimensional
governing partial differential equation is derived first with regard to evolutionary probability density
function of the stochastic response of non-linear structures. For the dynamic reliability problem, a virtual

stochastic process associated to the extreme value of the studied stochastic process is firstly constructed in
such a way that the extreme value equals the value of the virtual stochastic process at a certain "instant of
time". The probability density evolution method is then employed to evaluate the instantaneous probability
density function of the virtual stochastic process. After that, dynamic reliability could be evaluated from the
extreme value distribution, instead of the level-crossing process theory. An example, of which deals with a
nonlinear frame structure subjected to ground motions, is illustrated to validate the proposed method.

摘要: An automatic relative radiometric normalization algorithm of multi-temporal remote sensing images
based on pseudo-invariant neighborhood was introduced in this paper. The main purpose of this research
was to develop a robust algorithm of relative radiometric normalization to minimize imaging differences of
multi-temporal satellite images. The main idea was to construct statistical regression model of relative
radiometric normalization by pseudo-invariant neighborhoods, which were obtained by extracting steady
ground point correspondences. The algorithm's detailed processes were as follows: First, a method of image
matching was applied to recognize ground point correspondences of multi-temporal remote sensing images.
Second, steady ground point correspondences were determined by matching results. Third, sample dataset
of steady ground point correspondences was obtained by pseudo-invariant neighborhoods. Finally, a
statistical regression model of relative radiometric normalization was constructed to calibrate imaging
differences of multi-temporal remote sensing images. By the experiments, we could see that the total
RSME of reference image and calibrated image way reduced apparently in comparison with the total
RSME of reference image and tin-calibrated image. We could conclude that this modified algorithm was
more accurate and efficient than traditional algorithm, and the result of calibration was more objective and
dependable.

摘要: It is key problem to study parameters sensibility of landslide stability analysis, especially correlation
of soil parameters should be considered in the research. A new model of landslide stability sensibility
considering of parameter correlation was advanced by analyzing existed results. The model is composed of
uniform design, limit equilibrium method and partial least squares method. Uniform design is better than
orthogonal design etc. in multifactor and multi-level sensibility analysis of landslide stability. Safety factor
of landslide stability can work out by limit equilibrium method. Partial least squares method can solve the
correlation of parameter on landslide stability sensibility. The model may apply to geologic hazards
especially in Three Gorges reservoir area, and has extensive adaptability and theory value.

摘要: In this paper, stabilization problems for a particular class of non linear continuous model with
time-delays in the form of Takagi-Sugeno(TS) are investigated. The considered models are of multiple
time-delays in state. Some new sufficient conditions for stability and stabilizability are given. They are
based on some PDC control laws and some matrix translation properties. First of all, we derive stability
conditions of unforced and forced system of considering model, respectively. We then discuss stabilization
problem with two cases: (i) unknown delays and (ii) known delays, and give stabilization conditions via
LMI. All given conditions are in the form of LMI's and it's easy to be checked by means of MATLAB.
Finally, two examples are worked out to illustrate the theory.

摘要: Because deformation discipline with time of monitoring points at different locations of dams is
different, some models whose deformation are interrelated with time are preplaced, and the best model
With the least forecast errors is looked for, the influence of the water level and temperature is considered,
then the deformation model considering factors of time and water level and temperature is established.
Parameters of the model considering factors of time and water level and temperature are taken as state
vectors, then the Kalman filter model considering factors of time and water level and temperature is
established, on the basis of Kalman filter model considering factors of time and water level and temperature,
and the deformation value of the monitoring point on the dam is forecasted. Calculation shows the fitted
and forecast accuracy of the Kalman filter model considering factors of time and water level and
temperature is better.

摘要: A modularization method has been proposed here for the full scope real-time simulation of a
large-scale hydropower plant. In this method, the full scope dynamic simulation model can be decomposed
into several subsystems that can be calculated independently in every time step, and each kind of subsystem
model is developed to be a standard module. Using object-oriented modeling method for the simulation of
hydropower plant protection systems, a general relaying module is developed to model a versatile
protective relay, and a specific protective relay can be modeled through initialization of the general relaying
module with different specific parameters and coordination settings. By doing these, the simulation time is
reduced considerably, and the full scope simulation model of hydropower plant is convenient to develop,
modify and maintain.

摘要: The recently developed probability density evolution method (PDEM) is introduced to study
non-linear random response of earthquake-excited structures. In the method, a completely uncoupled
one-dimensional governing partial differential equation is derived first with regard to evolutionary
probability density function of the stochastic response of non-linear structures. Utilizing the orthogonal
expansion method, the stochastic process for earthquake ground motion is carried out based on the Hartley
orthogonal expansion bases. In order to capture the main probabilistic characteristics of seismic ground
motion, we carry out the orthogonal expansion directly on the seismic displacement process. Further by
using the principle of energy equivalence, the expanding expressions of seismic acceleration process is
achieved with 10 random variables. Therefore, it is natural to combine the PDEM and the orthogonal
expansion model of ground motion to study the non-linear random earthquake response. An example, of
which deals with a non-linear frame structure subjected to ground motions, is illustrated to validate the
above approach.

摘要: In order to solve the problem of optimal deployment in static hybrid sensor networks, an particle
swarm optimization for integer planning is adopted to optimally deploy the relay nodes so as to obtain the
optimal energy efficiency by minimizing the average path length. The modified particle swarm
optimization can improve calculation efficiency, because the method restricts the evolution within integer
space has decreased the searching probability in many unwanted non-feasible solution field The
simulations showed that the optimal deployment of relay nodes can largely improve the energy efficiency
and the location of sink has direct affect on the optimal efficiency.

摘要: The properties of the conductive adhesive such as resistivity, shear strength and water-absorb ratio of
the adhesive filled with the filler of Ag-coated graphite from electroless silver plating procedure were
studied using the universal meter, the diagrams of scanning electron microscopy (SEM) and the shear
strength testing. The results from the experiment showed that the resistivity of the Ag-coated flake graphite
was relative lower when the addition was less than 50% (wt) to that of the conductive adhesives filled with
pure flake graphite, The shear strength of the conductivity adhesive filled with Ag-coated flake graphite
was usually higher than that one filled with un-treated graphite and the peak values occurred when the filler
addition was equal to 30%.

摘要: A numerical simulation is proposed to study the dynamics expansion characteristics during the
material irradiated by a high-intensity laser beam. The ionization effect and the local mass and momentum
conservations for plasma expansion are considered in this model. As an example of carbon target, the
plasma flow dynamics into a vacuum, like ionization degree, plasma number density and space pressure are
studied in detail. The results show the plasma temperature strongly affects the ionization fraction and the
ionization effect evidently influences the plasma dynamic expansion behavior. The space pressure of
plasma decreases along with the plasma expansion.

摘要: The 3-D elasto-plastic finite element method (FEM) was used to analyze the thermal stress in the
laminated composite (SiC/6061Al) under the condition of a temperature cycling of 200 degrees C-30
degrees C- 200 degrees C-30 degrees C. The results from the FEM analysis showed that the hysteretic peak
value of the von Mises equivalent stress in the substrate 6061Al was increased significantly as the
temperature loading cycles processed on but it was nearly the same after the first cycle in the interface layer
SiC of the laminated composite. The elastic strain in the substrate 6061Al varied within the range of
-0.15% to 0.15% and the maximum plastic deformation was equal to about 0.26%, The results also showed
that the maximum normal stress Sx was increased from 32.8 MPa to 87.9 MPa after ten cycles and the
work-hardening of the substrate 6061Al occurred during the stress and strain hysteresis loop.

摘 要 : The distribution of electromagnetic parameter in stratum is a basis of the design of the
through-the-earth communication system and selecting of the equipments' electrical parameters. Because
there is great difference of electromagnetic parameter between different geological strata, a great bias will
be brought out during the research of the electromagnetic propagation characteristics of the
through-the-earth communication based on the simplified stratum media model. In order to solve this
problem, Kriging interpolation algorithm is originally adopted to setup a stratified stratum media model and
estimate the distribution of the electromagnetic parameters in the mutant stratum media. By this
interpolation method, the high precise electromagnetic parameters and stratum media model can be
provided for the design of communication system and the numerical calculation of electromagnetic
propagation.

摘要: Binary arithmetic codes with forbidden symbols (named error correction arithmetic codes: ECAC)
can be modeled as finite state machines and treated as variable length trellis codes. In this paper, a novel
iterative joint source channel decoding algorithm is proposed for decoding trellis based error correction
arithmetic codes. Unlike the conventional iterative decoding algorithm, it is needless to use the additional
check codes such as CRC during the encoding, the proposed algorithm utilizes the Monte Carlo methods to
detect the error bit directly. Furthermore, the outer error detector can not only detect the error bits but also
provide the probability of the error location to the inner error corrector so as to accelerate the decoding
process. Experimental results show that the proposed algorithm has some significant performance

improvements over some conventional decoding algorithms in terms of the symbol error rate, while the
increased computational complexity can be accepted.

摘要: A criterion using residual voltage and fuzzy decision to improve the successful rate of reclosing is
proposed. Residual voltage of the faulted phase still remains after a single phase to ground fault occurs
followed by the faulted phase breaking because distributed parameters of the high-voltage transmission line
and coupling capacitance between one phase and another phase transmission fines exist. Therefore, the
residual voltage can be used to distinguish between permanent faults and transient faults of transmission
lines. However, a permanent fault may be regarded as transient one when permanent single-phase fault to
ground occurs near either end of the transmission tine according to the existing residual voltage scheme. In
this case the system stability will be threaten. In order to overcome this problem, a new scheme using fuzzy
decision is proposed in this paper, the information of capacitance coupling voltage and the boundary
condition will be used to revise the present criteria, so that the correct rate of judgment can be improved
extremely. A classical model with two inputs and one output is used to design the fuzzy controller, a STD
industrial control computer system is used as the hardware platform. The analysis and test results show that
the new criterion can be widely applied in protective relaying with reclosing, especially digital relaying of
power systems.

摘要: A distributed & hierarchical NN (DHNN) system based on the integrated module architecture and
hierarchy architecture is proposed in this paper. The DHNN system adequately uses the powerful function
of artificial neural networks at aspects of pattern identification, nonlinear-approaching, associative memory
et al. Its information processing mechanism coincides with the processing law of
classification-sketchiness-accuracy in human biologic NN system. This system not only can deal with the
advanced information required by fault location for HV overhead transmission fines but accurately locate
the fault sites. Thus this method for fault location presented in this paper can thoroughly eliminate the
disadvantages in other extant fault location methods, such as convergence to the false root or divergence in
the procedure of iteration, which result in the great location error in practice. This paper pioneers a new
direction to the study and application on fault location. Results from theoretical analyses and simulations
by EMTP show that fault location precision of this method can completely satisfy practical requirements.

摘要: A multi-agent system (AMS) based integrated framework in support of adaptive and active learning
in individual learning spaces is proposed in this paper. In the adaptive individual learning space, the key
issue is how to dynamically generate personalized learning path consisting of domain concepts and present
associated learning objects catering for a learner's knowledge state and learning preference. As to this, a
novel domain model with ontology layer, metadata layer and learning objects layer is proposed, and an
efficient searching algorithm for the presentation generation base on the proposed domain ontology model
is put forward.

摘要: A passive polarization beam splitter in silicon-on-insulator (SOI) waveguides, which consists of two
3-dB multimode interference (MMI) couplers and two Mach-Zehnder interferometer (MZI) arms with the
same length but different rib widths, has been proposed recently and a numerical method of design is
needed because the analytical solution for this 3-dimensional (31)) SOI waveguides is difficult to achieve.

The scalar finite difference beam propagation method (FD-BPM) is used to design the 3-dB MMI couplers
and the positions of the input or output waveguides and the length of multimode waveguide are determined.
In our design, the length of MMI couplers is 1228 micron when the width of rib is 36 micron. The
propagation constants of TE-polarized and TM-polarized mode supported by 3D rib waveguides on SOI are
calculated by the Semi-vector FD-BPM which is polarization related. From these data obtained for different
rib widths (from 2.0 micron to 4.0 micron), the appropriate length of MZI arms is selected. In our example,
the widths of two arms are 3.4 micron and 2.0 micron respectively and the length of arms is 1506 micron.
The TE-polarized light and TM-polarized light are input to the splitter separately and the Semi-vector
FD-BPM is used to check the design.

摘要: An adaptive algorithm of relative radiometric normalization for multi-temporal remote sensing
images based on feature corner was introduced in this paper. The main purpose of this research was to
explore an automatic and robust algorithm of relative radiometric normalization to minimize imaging
differences of multi-temporal satellite images. The main idea was to construct statistical regression model
of relative radiometric normalization by extracting steady ground point correspondences. The algorithm's
detailed processes were as follows: First, a method of image matching was applied to recognize steady
ground point correspondences of multi-temporal remote sensing images. Second, a statistical regression
model of relative radiometric normalization was constructed to calibrate imaging difference of
multi-temporal remote sensing images. By the experiments, we could see that the total RSME of reference

image and corrected image was reduced apparently in comparison with the total RSME of reference image
and uncalibrated image, and the hue of corrected image was looked more like that of reference image. We
could conclude that this modified algorithm was more accurate and efficient than traditional algorithm, its
adaptive characteristic made it easy to be integrated, and it had more feasibility and applicable value.

摘要: There is moral hazard caused by workers' shiftless actions because of asymmetry information
between the enterprise and workers in the management of an enterprise. It is necessary to make a long-term
wage contract to workers' actions. Based on principle-agent theory and human resources management
practices, an incentive compatible dynamic wage contract model is formalized and simulated. According to
the consequences of simulating, the optimal contract is characterized analytically. The optimal dynamic
wage contract not only can offer incentives to workers and make them work hard, but also can smooth the
enterprise's incentive costs and help the enterprise realize the Pareto optimal resource allocation. It proves
the contract model is valid and provides some reasonable conclusions for enterprises.

摘要: If prices follow a random walk model, this implies informational efficiency Since presence of a unit
root is not a sufficient condition for a random walk, we need to test the presence of autocorrelation in
residuals. At the same time, VR test is important because an important property of the random walk
hypothesis is that the variance of random walk increments should be a linear function of time. MVR test
provides a procedure for the multiple comparison of the set of variance ratio estimates with unity. The
conclusions tell us we cannot reject weak-worm efficiency market hypothesis in Chinese futures markets.

摘要: In order to diagnose the faults of complex reciprocating machine, such as internal-combustion engine
(ICE), the vibration signals under normal and abnormal patterns were measured by experiments. According
to the nonstationarity of ICE signals, the scale-wavelet power spectrum (SWPS) of si signals was obtained
by continuous wavelet transform (CWT). The wavelet power (WP) distribution on different scales of each
pattern is observed to be similar and mainly concentrated in particular scope of 1 similar to 32. By
analyzing the diversity of SWPS distribution, the WP which is most sensitive to the characteristic of each
pattern were extracted by the reduction algorithm of rough set (RS theory) as feature and taken as input to
train the back-propagation neural network (BPNN). By the trained BPNN to dia,gnose the fault signals
under detection, the correctness rate is 100%. The fault diagnosis method integrated on SPWS, RS and
BPNN demonstrates to be efficient and feasible. It has preferable engineering applicability and referenced
value to diagnosis for complex machines.

摘要: This paper studies robust performance analysis of H2/H infinity control problem in time-varying
systems. In the case where the state-space matrices of the system depend affinely on the uncertain
parameters, it is known that recently developed extended or dilated linear matrix inequalities (LMIs) are
effective to assess the robust performance in a less conservative fashion. This paper further probes into
those preceding results and proposes a new form of extended LMIs for time-varying H-2/H-infinity.
controllers synthesis. The new method enables us to parameterize controllers without involving the
Lyapunov variables in the parameterization. The numerical simulations prove the validity of this
framework.

摘要: A signal processor based on an bi-stable aperiodic stochastic resonance (ASR) is introduced firstly.
The processor can detect the base-band binary pulse amplitude modulation (PAM) signal. A digital image
watermarking algorithm in the discrete cosine transform (DCT) domain is implemented based on the
processor. In this algorithm, the watermark and the DCT alternating current (ac) coefficients of the image
are viewed as the input signal and the channel noise of the processor input, respectively. In conventional
watermarking systems, it's difficult to explain why the detection bit error ratio (BER) of a watermarking
system suffering from some kinds of attacks is lower than that of the system suffering from no attack. In the
present watermarking algorithm, this phenomenon is systematically analyzed. It is shown that the DCT ac
coefficients of the image as well as the noise imported by the attacks will cooperate within the bi-stable
ASR system to improve the performance of the watermark detection.

摘要: Ti(C, N)-based cermet cutting tools were prepared by vacuum sintering and tested in dry machining
of normalized medium carbon steel (AISI1045) at various combinations of cutting speed (Vc), feed rate (f),
and depth of cut (a(p)). And the wear mechanism was investigated in detail using scanning electron
microscopy (SEM) and electron-probe microanalysis (EPMA). Comparing to the cemented carbide YT15
and cermet TN20, the newly fabricated cermet tools exhibited better performance and higher wear
resistance. For Ti(C, N)-based cermet tools, the wear mechanism was predominantly controlled by the flank
wear under all cutting condition. It was found that the removal of the ceramic grain and abrasive wear were
the main source of tools failure. In addition, adhesion and oxidation were also observed.

摘要: Binary arithmetic codes (AC) with forbidden symbols (FS) can be modeled as finite state machines
and treated as variable length trellis codes. In this paper, the relationship between the coding parameters
and the number of states is discussed, and a novel adaptive source and channel coding system is proposed
based on the relationship. The proposed coding system can adjust adaptively the coding parameters
according to the source and channel information so as to achieve the optimal performance. This coding
system can be used to transmit images over wireless channel, and the coded bit stream can be decoded by
using general list Viterbi decoding algorithm. Experimental results show that this system has some

摘要: An integral sliding mode control method is presented for a class of nonlinear systems. The control
design is divided into two steps. Firstly, a linear system is derived from the original complicated system,
and an asymptotically stable controller is designed for this simplified system using linear system design
method. Secondly, based on the stable closed-loop linear system, an integral sliding surface is constructed,
and a control is developed to ensure the reachability of the sliding surface. Consequently, the stabilization
of the whole complicated system is achieved. The stability of the closed-loop system is also analyzed.
Finally, simulation studies are included to illustrate the effectiveness of the proposed method.

摘要: The passive components ill the integrated optic chip applied by fiber optic gyroscope are analyzed
and designed on silicon-on-insulator (SOT) wafers. These components include a polarizer and a multimode
interference (MMI) coupler. The NM coupler acts as the traditional Y-Branch power splitter. The polarizer
consists of two 3dB NM couplers and two straight single mode waveguides between these two NM
couplers. These two straight waveguides have equal length but have different rib width. The mode
propagation constants of TE or TM light are not same and the appropriate selection of the length of the
straight waveguide will result in the splitting of TE and TM light. The scalar or Sernivectorial fimite
difference beam propagation method (FD-BPM) is used to design these photonic components. The mode
parameters of straight waveguide with different rib width are analyzed by Semivectorial FD-BPM and the
reasonable length of straight waveguide was selected. The NM coupler is designed by scalar FD-BPM and
the length of multimode waveguide and the positions of the input or output ports are determined accurately.
The curving waveguide is avoided completely, therefore the design is more reliable and the fabrication of
the device is much easy.

摘要: An approach to get the block DCT coefficients from one size to any size at arbitrary position of an
image/video frame in the DCT domain directly by simple cutting, shifting and pasting operations is
proposed. Many existing approaches, which require the input block(s) to align with the border of the output
block, could be considered as special cases of the proposed approach. The practicality of the approach is
illustrated by an example where an image can be resized arbitrarily in the DCT domain directly.

摘要: In interior-point algorithms, it is well known that algebraically equivalent paths give rise to different
trajectories to the optimal sets, together with different step length rule. Based on a specific algebraic
transformation and frame of the KMM algorithm, a new infeasible interior point algorithm for linear
programming is proposed in this paper, and its global convergence is established. Finally, two numerical
examples are provided to show the efficiency of this method.

摘要: m-ary n-cube (denoted by Q(n)(m)) is an important network topology for parallel processing
computer systems. Some methods of forming big cycle from small cycles and links have been developed.
Basing on which, we has proved that in m-ary n-cube, there exists a cycle of every length from 3 to vertical
bar V(G)vertical bar inclusive and all kinds of length cycles have been constructed in. This important
Hamilton property of m-ary n-cube can be applied in the topology design of computer networks to improve
the network performance.

摘要: In this paper a new algorithm for fault-tolerant routing based on depth-first search is developed. Its
performance is analyzed for m-ary n-cube networks in presence of an arbitrary number of components
being damaged. We derive an exact expression for the probability of routing messages via optimal paths
from the source node to obstructed node. The probability of routing messages via an optimal path between
any two nodes is a special case of our results, and can be obtained by replacing the obstructed node with the
destination node. It is also showed that in the presence of component failures the new algorithm can route
messages via an optimal path to its destination with a very high probability.

摘要: Panchromatic (Pan)-sharpening of multispectral (MS) bands is an important technique in various
applications of satellite remote sensing. In this paper, We apply the support value transform (SVT) to
Ikonos image fusion. The fused saliency features are represented by support values and extracted by SVT.
The low-resolution MS bands are resampled to the fine scale of the Pan image and sharpened by injecting
the detailed features extracted from the high-resolution Pan image. The fusing results on Ikonos MS + Pan
data demonstrate that the proposed image fusion method is effective and efficient.

摘要: In this paper, the concept of finite time bound (FTB) for linear singular system with uncertain
parameters is presented. Then, finite-time control problem is considered for uncertain singular systems with
norm bounded exogenous disturbances. Sufficient conditions are given for robust finite-time stabilization
via state feedback. Such conditions can be reduced to feasibility problems involving linear matrix
inequalities (LMIs). A detailed solving method is proposed for the restricted linear matrix inequalities.
Finally, an example is given to show the validity of the methodology.

摘要: The problem of estimating the sensor's input-output characteristic is being increasingly tackled using
software techniques. Artificial neural network (ANN) method is a useful curve-fitting method. A model of
PRTD (Platinum Resistance-temperature Device) using radial basis function (RBF) neural network is
presented. After the successful training of ANN using scale division data, it is then used as a neural
estimator to calculate the temperature from resistance. Suitable spread parameter of the model is
determined as 0.3 similar to 1.0. The absolute error is 0 degrees C for data in specimen and 0.03 similar to
0.06 degrees C out of specimen. The results indicate that model presented is simple in algorithm, accurate
and steady. Software and hardware composition of VI system and virtual realization process of temperature
measurement based on joint programming of LabVIEW and MATLAB including front panel and block
diagram are given. Running results indicate that virtual realization method integrating ANN and VI is easy
and inexpensive and can be used in other application fields for reference.

摘要: In this paper, according to information that is slightly characteristic of adaptive adjust prediction and
update operators, the paper adopts the adaptive lifting wavelet transform algorithm for accurately matching
the processed information. This algorithm can effectively decrease the amount of calculation, as well as the
computational complexity of information wavelet analyzed, which can carry out the same address operation
and advantages that recur in the laser exploration system realization. Secondly, this paper analyzes how to
create a threshold of noise-filtering, using the noise features in laser exploration system. The algorithm can
also adapt to the requirement for detecting weakened signal occuring in high noise through the definition of
floating threshold. The results show that the new algorithm has improved the traditional algorithm and
effectively maintains signal detail while filtering out the signal noise, leading to an improved.

摘要: To overcome the difficulty of fusing statistical feature and structural feature in the research on
handwritten numeral recognition, Principal Component Analysis is used to reconstruct numeral model and
estimate the numeral reconstructive error based on the statistical information of digit structural feature. At
the same time, the height-width ratio and Euler value of numeral is extracted. Recognition of the digit
character is completed through combining the neural network and Bayes classifier respectively
corresponding to the three type features. The recognition rate of this method is 90.73% on handwritten
numeral database.

摘要: The empirical mode decomposition (EMD) is a new method for adaptive decomposition of nonlinear
and non-stationary signals. This paper combines the EMD method and the conventional response
modulation method to analyze the fault in the rolling bearing. B-spline EMD is also investigated to extract
the high frequency components of the signal. Then we use discrete time Fourier transform (DTFT) to get
the refinement spectrum analysis. The results show that the combination of these two methods performs
excellently.

Abstract:The properties of the conductive adhesive such as resistivity, shear strength and water -absorb
ratio of the adhesive filled with the filler of Ag-coated graphite from electroless silver plating procedure
were studied using the universal meter, the diagrams of scanning electron microscopy (SEM) and the shear
strength testing. The results from the experiment showed that the resistivity of the Ag-coated flake graphite
was relative lower when the addition was less than 50 % (wt) to that of the conductive adhesives filled with
pure flake graphite. The shear strength of the conductivity adhesive filled with Ag-coated flake graphite
was usually higher than that one filled with un-treated graphite and the peak values occurred when the filler
addition was equal to 30%.

Abstract:In this study, a novel procedure is presented for control and analysis of multiple autonomous
agents with point mass dynamics achieving flocking motion. Two control laws are proposed for a group of
autonomous agents to achieve flocking formations related to two different centers (mass center and
geometric center) of the flock. The first one is designed for flocking motion based on mass center and the
second for geometric center. Distance-dependent adjacency matrix is used to quantify the way agents
influence each other. Theoretical analysis is established to indicate the stability (cohesiveness, collision
avoidance and velocity matching) of the control systems using classical Lyapunov theory. Finally, a
simulation example is demonstrated to validate the theoretical results. &copy;2008 IEEE.

Abstract:The fault diagnosis in tribosystem was a difficult problem due to the complex structure of the
tribosystem, the nonlinear character of the tribosystem and the presence of multi-excite sources. Usually,
one method of fault diagnosis can only inspect one corresponding fault category. In this paper, oil
monitoring and vibration monitoring methods were utilized together to diagnose the rolling bearing faults
on a homemade bearing bench. Five tests were conducted under different conditions. Oil samples and
vibration data were collected regularly and analyzed respectively. Then rough sets theory was introduced
into the process of choosing parameters and the knowledge discovery in union diagnosis. Some knowledge
was obtained finally. &copy; 2008 IEEE.

thermomechanical actuated compliant mechanisms with geometric nonlinearities is studied. The meshless
method is employed to discretize and solve the governing equations. The optimization formulation is
developed using the SIMP and meshless methods, which is solved by MMA. The nonlinear design
sensitivity analysis is performed by incorporating the adjoint approach into the meshless method. The
filtering of the sensitivity developed corrects the topology including few discontinuous scattered points.
The availability of the proposed method is demonstrated by designing widely studied compliant actuators.

Abstract:According to the randomness of multiplication of the carrier for the avalanche photodiode (APD),
a mathematic model of the false alarm ratio (FAR) and the multiplication factor of APD were established
based on the statistics. Through monitoring FAR for avalanche noise, the curve between bias voltage and
temperature characteristic and the temperature coefficient of breakdown voltage have been obtained. The
experiment shows that false alarm method not only can gain the breakdown voltage of APD in different
temperature accurately, but also can determine the degree of avalanche breakdown. The temperature
compensating circuit designed for the bias of APD can guarantee the normal operating of APD in a large
variation of temperature, it is suitable for the photoelectric system that the high-frequency continuous
signal detect.

Abstract:This paper is concerned with the Holling-Tanner prey-predator model subject to the homogeneous
Neumann boundary condition. We will show that under certain hypotheses, even though the unique positive
constant steady state is uniformly asymptotically stable for the dynamics with diffusion, non-constant
positive steady states can exist due to the emergence of cross-diffusion. The biological implication of
cross-diffusion means that the prey species exercise a self-defense mechanism to protect themselves from
the attack of the predator. Our result also demonstrates that cross-diffusion can create Stationary Patterns.

characterization indicated that the as-prepared samples belonged to cubic sphalerite crystal phase ZnS. The
images of scanning electron microscopy showed that the well-dispersed ZnS microspheres were obtained
and microspheres were comprised of ZnS nanoparticles with diameter 20-30 nm. When the sulphur source

Abstract:The 3-D elasto-plastic finite element method (FEM) was used to analyze the thermal stress in the
laminated composite (SiC/6061A1) under the condition of a temperature cycling of 200&deg;C-30&deg;C200&deg;C-30&deg;C. The results from the FEM analysis showed that the hysteretic peak value of the von
Mises equivalent stress in the substrate 6061 Al was increased significantly as the temperature loading
cycles processed on but it was nearly the same after the first cycle in the interface layer SiC of the
laminated composite. The elastic strain in the substrate 6061A1 varied within the range of-0.15% to 0.15%
and the maximum plastic deformation was equal to about 0.26 %. The results also showed that the
maximum normal stress Sx was increased from 32.8 MPa to 87.9 MPa after ten cycles and the
work-hardening of the substrate 6061A1 occurred during the stress and strain hysteresis loop.

Abstract:As the band of networks increases, the process speed of network-based intrusion detection system
(NIDS) hardly keeps up with the speed of networks. By arranging several sensors to deal with the traffic in
parallel, the intrusion detection system's speed can be significantly increased. How to split the traffic to the
sensors is the key problem of a parallel intrusion detection system. To resolve the problems, load balance
has to be concerned. There is an emerging need for parallel intrusion detection techniques that can keep up
with the increasing network throughput. A novel algorithm of load balance in the parallel IDS (Intrusion
Detection System) was proposed to improve detection ability of parallel IDS. The algorithm was adopted to
hash the network packet header information in data packet, to map the corresponding packet to the scope of
the sensors' number, and to adjust the scope according to the performance and load of each sensor.
Theoretic analysis and experimental results demonstrate that the algorithm can dispatch data packets
reasonably and utilize all the sensors' sources effectively. &copy; 2008 IEEE.

Abstract:The performance of phase encoding and decoding based on phase shift superstructured fiber
Bragg grating (SSFBG) in the optical code division multiplexing (OCDM) system was investigated and
analyzed. The correlation characteristics for phase shift SSFBG based en/decoder were evaluated by
considering input pulse width, grating refractive index modulation amplitude and wavelength mismatch
between encoder grating and decoder grating. The impact of fiber dispersion on OCDM transmission over
single-mode fiber (SMF) is also estimated. The theoretical results show that the degradation of coding
performance is obvious under the impact of increasing of input pulse width, encoderdecoder wavelength
mismatch and fiber dispersion, and there is a contradiction between correlation property and insertion loss
of SSFBG en/decoder, we need to select moderate refractive index modulation amplitude of SSFBG
grating.

Abstract:In order to design and make multimode interference (MMI) couplers, the imaging positions must
be located accurately. The implicit finite difference beam propagation method (BPM) in three-dimensional
alternate directions is used for the analysis of strongly guided and weakly guided multimode interference
couplers. The length of multimode waveguide, the positions of input guides and output guides are
determined precisely. The equivalent width W<inf>eq</inf> and the beat length L<inf>c</inf> of two
lowest modes of multimode waveguide are obtained first by the numeric modeling of a symmetric
interference MMI, and then these parameters together with BPM are used for the device design. The
imaging positions showed the close results between BPM and the predictions of the mode propagation
analysis CMPA) theory, however, W<inf>eq</inf> and L<inf>c</inf> were obtained by the BPM, MPA
theory will not give any result without these parameters. The three dimensional (3D) waveguides are not
treated as 2D waveguides by means of effective index method (EI). therefore, this method can be used
directly to 3D waveguides. As a kind of numerical method, some normal approximations are not introduced
as MPA theory, so it will ensure the precision of calculation and can afford reference for practical MMI
device design.

Abstract:The problem of the H<sub> infinity </sub> robust control of a class of uncertain Takagi-Sugeno
(T-S) fuzzy model with state and input time delays was discussed. Several sufficient conditions for the
stabilization in considered systems and the design procedures of H<sub> infinity </sub> controller were
derived by using parallel distributed compensation (PDC). The designed controller could make sure that the
closed-loop system was asymptotically stable and the effect of the disturbance input on the controlled
output was reduced to a prescribed H<sub> infinity </sub> norm level. Simulation results showed that the
proposed method was effective.

Abstract:Silicon dioxide was used to strengthen and toughen unsaturated polyester resin. The results show
that, in the employed experimental conditions, the performances of the product are greatly affected by the
dosage (mass fraction) of silicon dioxide, that the tension fracture energy reaches the maximum value at a
SiO<inf>2</inf> dosage of 8%, and that the curing shrinkage rate becomes low at a SiO<inf>2</inf>
dosage of 8%-12%. Moreover, FT-IR spectra were used to reveal the effects of the characteristic groups and
hydrogen bonds on the performances of the composite. The results indicate that the absorption peaks of
unsaturated double bonds and hydroxyls greatly improve with SiO<inf>2</inf> dosage when the dosage is
less than 10%.

Abstract:The paper first introduces the basic principle of Karhunen-Loeve decomposition for stochastic
processes, and outlines the essential properties of the decomposition. A method based on the Hartley
orthogonal bases is proposed to decompose stochastic processes. It is proposed to directly carry out the
orthogonal expansion of the seismic displacement to capture main probabilistic characteristics of the
seismic ground motion with only a few terms of the series. Based on the principle of energy equivalence,
the expanding expression of seismic acceleration process is achieved. The seismic process is expanded into
a linear combination of deterministic functions modulated by 10 uncorrelated random variables.

paper addresses the task of developing an effective and efficient method of clustering the text document. To
meet this requirement, we first extract the modifying relations (MR) from the sentences and then organize
them as feature set for representing the document. A novel similarity measure is proposed on the basis of
MR-vectors in this paper. We use agglomerative hierarchical clustering algorithm in the experimental work
and compare the results with other previous studies. &copy; 2008 IEEE.

Abstract:The stability of a slope in a dam region will be affected by atomization water flow of the dam. The
intensity and distribution of atomization water flow is necessary to evaluate the slope stability. So it is very
important to determine the intensity and distribution of atomization water flow. In this paper the fuzzy
evaluation is used to determine the intensity and distribution of atomization water flow in a slope which is
adjacent of a dam. Furthermore, the results of different fuzzy operators are compared, some conclusion is
presented. It shows that the intensity is all the same no matter which fuzzy operator is choose, where the
distribution is related to the fuzzy operator closely.&copy; 2008 Science Press Beijing and Springer-Verlag

Abstract:In this paper, we propose an aperiodic stochastic resonance (ASR) signal processor for
communication systems based on a bi-stable mechanism. This processor can detect base-band binary pulse
amplitude modulation (PAM) signals. In this processor related parameters can be adjusted. The adjustment
mechanism is explained from the perspective of the conventional noise-induced nonlinear signal processing.
To demonstrate this processors usability, based on it we implemented a digital image watermarking

alternating current (ac) coefficients of the image are viewed as the input signal and the channel noise,
respectively. This phenomenon that the detection bit error ratio (BER) of the system suffering from certain
attacks is lower than that of the system not suffering from any attack is systematically analyzed. &copy;

Abstract:The multimode interference (MMI) couplers, which operate at 1.55 microns in deep rib InGaAsP/
InP waveguide with large lateral confinement and tunable power splitting ratios, are of high interest in
integrated optics. The gold contacts are applied on the top of waveguides where tuning is desired and the
plasma effect will lead to negative refractive index change. The three-dimensional (3D) finite difference
beam propagation method (FD-BPM) is used to model the tunable MMI couplers. The length of a 2x2
overlap-MMI is determined by FD-BPM, so the longitudinal position of tuning spots is obtained. The
position of gold contacts with two types, the edge-pads or center-pad, are also determined. In our design,
the length of MMI is 180 microns. If the width of pads is 50 micros and the refractive index is tuned from 0
to -0.027, the power ratio is tuned from50:50 to maximums 88.5:11.4. For deep rib structure, the effective
index (EI) method can not be used to simplify the 3D waveguide to plane waveguide because its lower
precision, and then the direct 3D FD-BPM simulation is necessary for the design of 3D MMI couplers.

Abstract:In this paper, a new approach to H<sub> infinity </sub> controller design for a class of uncertain
discrete T-S fuzzy systems are proposed. According to the Lyapunov stability theory as well as parallel
distributed compensation (PDC), several sufficient conditions for stabilization of considered systems are
derived. The design procedure based on LMI for the fuzzy robust controller is given, which guarantee the
closed-loop system is asymptotically stable and the effect of disturbance input on the controlled output is
reduced to a prescribed level. The simulation results show the proposed method is effective.

Abstract:The structural parameters of butterfly multimode interference (MMI) coupler need to be
determined according to the special ratio of power splitting when the device is designed. The coupling
length, as a characteristic parameter of rectangular MMI coupler, is determined by the finite difference
beam propagation method (FD-BPM) which is applied to the modeling of symmetrical interference
rectangular MMI coupler and then the structural parameters of butterfly MMI coupler are designed by the
formulas of mode propagation analyse (MPA) method which is an approximate method. Finally the
FD-BPM is used to correct the parameters of butterfly MMI couplers, including the structural parameters
and the ratio of power splitting. It is indicated by an example of practical device in SOI wafer that the
length of butterfly MMI coupler obtained by simulation is more than the length expected by MPA theory
within the range of two to four micrometers. The actual power splitting ratio is lower than the predicted
values of MPA theory. And the further the shape of butterfly MMI coupler departures from the shape of
rectangular MMI coupler, the more deviation grows between these two values.

Abstract:This paper presents a unified relay protection system modeling method both for simulation and
settings calculation of hydropower plant protection systems. In this method, the coordination of protection
systems is described by the coordination matrix which is corresponding to the state of hydropower plant
operation conditions and the topology of the electrical network. Based on coordination matrix, the settings
calculation results can be directly passed to the setting variables of the simulation models of relay
protection systems. Thus, the settings calculation models and the function simulation models of protection
systems are developed to have unified models. By doing this, the developed models are versatile for
different operation conditions of hydropower plant and different topologies of the electrical network
through modifying the coordination matrix. And finally, an example is given to show the effectiveness of
this method. &copy; 2008 IEEE.

Abstract:The physical mechanism of signal processing based on the aperiodic stochastic resonance (ASR)
system is analyzed, and a statistical approach for recovering the binary signal is proposed. The mean of all
the samples in steady-state, instead of the only sample at the end time of each bit duration or the mean of
all the samples in each bit duration, is used to recover the input binary signal to improve the performance of
the system. Simulation results show that the proposed approach can improve the performance of ASR
signal processor. The synchronization issue for practical application is also addressed and the solution is
given.

Abstract:A 3-D elastic finite element model was developed to investigate the stresses distribution of
bi-adhesive bonded joints (i.e., the bond line of joints filled with two adhesives of dissimilar toughness).
The effects of the loading mode on the stress distribution of joints, including the single-lap joints under
tensile loading (i.e., single-lap joints) and the butt joints under cleavage loading (i.e., cleavage joints), were
also studied in detail. Results showed that higher stress, distributed at the contact position of the dissimilar
adhesives placed along the bond line of bi-adhesive bonded joints. Also, the maximum stress of the
adhesive layer decreased when the length ratios and bonding sequence along the bond line, filled with two
dissimilar adhesives, was appropriately designed. At the same time, stress convergence in the adhesive
layer of bi-adhesive joints was also obviously reduced in contrast to the mono-adhesive joints. The
numerical investigation shows that it is necessary to take into account the change of loading modes when
optimizing the bi-adhesive joint design, because of the uneven and complex loading modes of the adhesive
bonding structure in the engineering applications.

Abstract:This paper introduced a genetic particle evolutionary swarm optimization (GPESO) for solving
the economic dispatch (ED) in power systems. GPESO is based on the genetic particle swarm optimization
(GPSO). GPSO was derived from the original particle swarm optimization (OPSO), which was
incorporated with the genetic reproduction mechanisms, namely crossover and mutation. To enhance the
search performance of GPSO, the differential evolution (DE) was incorporated to GPSO as a perturbation
to fight premature convergence and poor diversity issues observed in GPSO implementations. Constraint
handling was based on the stochastic ranking algorithm. GPESO was implemented to a 6 units system and
the simulation results showed that GPESO outperformed other PSO algorithms. &copy; 2008 IEEE.

Abstract:40 Gbit/s &times; 2 channel OCDM system based on superstructured fiber Bragg grating (SSFBG)
was experimentally investigated. A nonlinear amplifying loop mirror (NALM) within the receiver was
introduced to reshape the decoded pulse and suppress interference noise. The original 7.7 ps decoded pulse
was compressed to 3.6 ps as well as interference noise was suppressed effectively by exploiting nonlinear
switch characteristic of the NALM, and switching was obtained for peak signal power approximately 6 mW.
From the experimental results, it can be concluded that the performance of SSFBG based on OCDM system
was improved by using the NALM, and high speed all optical encoding and decoding with noise
suppression was required in optical packet-switched networks.

Abstract:To evaluate correlation characteristics for superstructured fiber Bragg grating (SSFBG) based
en/decoder in the optical code division multiple access (OCDMA) system, the effects on encoding and
decoding of input pulse width, encoder-decoder wavelength mismatch and grating refractive index
modulation amplitude are considered. The theoretical results show that the degradation of en/decoder
performance is obvious under the impact of increasing of input pulse width and encoder-decoder
wavelength mismatch. In addition, there is a contradiction between correlation property and insertion loss
of SSFBG en/decoder, it is need to select moderate refractive index modulation amplitude of SSFBG
grating. The theoretical model of coherent time spreading phase coding OCDMA system based on SSFBG
en/decoder is presented. Three different kinds of noise source are taken into account: multiple access
interference (MAI) noise, beat noise and receiver noise. Moreover, the system performance degradation as
a result of receiver's bandwidth limitation is evaluated. Optical thresholder and turbo code are employed to
improve the performance of coherent time spreading OCDMA system.

Abstract:The reactions were studied for the determination of bovine serum albumin (BSA) using
o-hydroxyphenylfluorone (o-HPF) as fluorescence probe reagent with fluorescence spectrophotometry. In
the B-R medium, o-HPF reacts with BSA to form the stable complex compound. The reaction system of
o-HPF and BSA was binary system, and the method for the determination of BSA was of good selectivity
and stability and simplicity. The linear range of o-HPF fluorescence spectrophotometric method was
1.32-18.54 &mu;g&middotmL<sup>-1</sup> The quenching constant and thermodynamics constant of the
fluorescence effects between BSA and o-HPF were calculated. The results showed that the non-covalent
binding forces were the binding force between o-HPF and BSA.

Abstract:Several cases of mal-operation of transformer differential protection with second-harmonic
blocking after clearance of external fault are reported. These mal-operations all occurred at the nonrestraint
region of percentage restraint plane. The previous theory cannot be utilized directly to analyze this
phenomenon. Therefore, a mathematical model for analyzing the transient course of external fault inception
and removal, together with the CT model involving the magnetic hysteresis effect, is proposed in this paper.
It is proved that the magnetic linkage of one CT core can be pushed into the region nearby the saturation
point by the high fault current with aperiodic component. As soon as the external fault is removed, the
magnetic linkage formed by the primary current with low amplitude is not high enough to pull the
operating point of the magnetic linkage back to the linear region. This phenomenon is named as CT local
transient saturation, which results in the big measuring angle error and relative smooth waveform. In this
case, the transformer differential protection using second harmonic blocking inevitably mal-operates. This
point of view is verified with the simulation tests. &copy; 2008 IEEE.

Abstract:The digital watermarking is investigated firstly. Some general approaches of binary image digital
watermarking algorithm are then analyzed in detail. A blind binary image digital watermarking algorithm is
proposed in the DCT domain. The correlativity of the inter-blocks' DC components is used to embed and
extract the watermark. No original binary image is needed when detecting the watermark. The involved
parameters are analyzed in detail. Some tests are performed on the logo image, Chinese characters image
and English characters image and the results show that the algorithm can be applied to binary images in
general and can provide robustness against common image processing. Comparison with its spatial
counterpart is made and the advantage of the proposed algorithm in DCT domain is demonstrated. &copy;

Abstract:In view of the defects in model of thermocouple characteristic using BP neural network (BPNN),
such as lower precision, varying output, instability( after repeated training, the output may be queer), a
model of thermocouple characteristic based on Generalized Regression Neural Network (GRNN) is
established. The paper gives the process of model building for Ni-Cr Constantan thermocouple
characteristic within -270 - 1000&deg;C. By means of network training, simulation and error analysis, the
scope of spread parameter of neural network model for Ni-Cr Constantan thermocouple was found. When
the spread is at 0.01-1.5, bigger errors appear mainly when thermo-EMF is less than 0V and greater than
75V. When it is at 0-0.01, the model has high precision and absolute error between simulation temperature
and setting temperature is close to 0&deg;C (the mean squared error is 0.00000703-0&deg;C). The results
indicate that the model presented has a quick convergent speed in learning process, a higher accuracy and
stability within a certain parameter scope. If the model is stored in CPU of an intelligent instrument, the
instrument will have high accuracy without increasing hardware cost. &copy; 2008 IEEE.

Abstract:The present paper introduces a new method using spectrofluorimetric analysis to determine the
concentration of hydrogen peroxide in rainwater. In this method, an oxidation reaction is conducted
between o-phenylenediamine (OPDA) and hydrogen peroxide in the buffer medium of NaAc-HAc at pH
4.48 to form a new product 2, 3-diaminophenazine (DAPN). Then the fluorescence intensity of DAPN is
measured and 426 and 554 nm are chosen as the excitation and emission wavelengths. Therefore, with the

foreknown concentration of input hydrogen peroxide, a series of fluorescence intensities of DAPN are
acquired according to a series of different concentration of hydrogen peroxide as input, greatly improving
the selectivity and sensibility of the system. A relationship between the input concentration of hydrogen
peroxide and the fluorescence intensity of DAPN is then obtained using a linear regression. Results show
that fluorescence intensity of DAPN is in proportion to the increase in the concentration of hydrogen

Abstract:The consensus problem in directed networks of multiagent is studied. A new notion, called
weighted average-consensus, is proposed and a class of distributed controller is applied to achieve global
asymptotically weighted average-consensus in networks of multiagent with fixed and switching topology.
We establish a connection between the Fiedler eigenvalue of the graph Laplacian and the performance of
this consensus controller. It is proved theoretically that the strongly connectedness of directed graph and a
class of directed graphs, called balanced graphs, play a crucial role in solving weighted average-consensus
problems. Based on the properties of balanced graphs, a group disagreement function (i.e. Lyapunov
function) is proposed for convergence analysis of this consensus controller in directed networks and for
robustness analysis in directed networks with switching topology. Finally, simulation example is provided
for consensus problem in networks with switching topology to validate the theoretical results.

Abstract:A novel, fast unblocking scheme for distance protection to identify symmetrical faults occurring
during power swings has been proposed in this paper. First of all, the change rate of three-phase active
power and reactive power being the cosine function and the sine function with respect to the phase
difference between the two power systems during power swings has been demonstrated. In this case, they
cannot be lower than the threshold of 0.7 after they are normalized. However, they will level off to 0 when
a three-phase fault occurs during power swings. Thereafter, the cross-blocking scheme is conceived on the
basis of this analysis. By virtue of the algorithm based on instantaneous electrical quantities, the calculation
of the active and reactive power is immune to the variation of the system power frequency. As the
integration-based criterion, it has high stability. Finally, simulation results show that this scheme is of high
reliability and fast time response. The longest time delay is up to 30 ms. &copy; 2007 IEEE.

Abstract:In this paper, a new approach is investigated for adaptive dynamic neural network-based H
<inf>&infin;</inf> control, which is designed for a class of non-linear systems with unknown uncertainties.
Currently, non-linear systems with unknown uncertainties are commonly used to efficiently and accurately
express the real practical control process. Therefore, it is of critical importance but a great challenge and
still at its early age to design a stable and robust controller for such a process. In the proposed research,
dynamic neural networks were constructed to precisely approximate the non-linear system with unknown
uncertainties first, a non-linear state feedback H <inf>&infin;</inf> control law was designed next, then an
adaptive weighting adjustment mechanism for dynamic neural networks was developed to achieve H
<inf>&infin;</inf> regulation performance, and last a recurrent neural network was employed as a
neuro-solver to efficiently and numerically solve the standard LMI problem so as to obtain the appropriate
control gains. Finally, case studies further verify the feasibility and efficiency of the proposed research.

Abstract:An efficient topology analysis algorithm for power network simulation modeling was proposed. In
this method, "Link-Line" was introduced into the graphic element library to connect two elements directly
and avoiding forming the complex linked list. Correspondingly, a Link-Line based original topology
description method is proposed, in this way, we can use the "nodes integration" algorithm more
conveniently, simply including two steps: Link-Lines integration and switches integration. This method can
deal with the dynamic topology changes of power network quickly using only local updating. Thus, the
topology analysis speed can be improved efficiently, and this is good for the real time simulation of power
network which is frequently changing because of the on-off switching operation. The test results applying
this algorithm to a real Chinese power grid show the efficiency of this method. &copy; 2008 IEEE.

Abstract:Natural feature tracking is a very important research topic in computer vision field and has been
used widely in Augmented Reality (AR). This paper gives a robust points tracking or transferring method
based on the Euclidean reconstruction technique for AR systems. The points to be tracked include the lost
natural features, and any points that are specified by the users. The proposed method distinguishes itself in
following ways: Firstly, it is stable as it remains effective even when the camera is moved rapidly. Secondly,
the proposed method is robust because it can operate normally as long as at least four pairs of reference
point correspondences can be found during the augmentation process. Thirdly, we propose an augmented
optical flow method by which the registration, annotation and video augmentation can still work even
under the circumstances of large changes in illumination and viewpoint during the entire process. Several
experiments have been conducted to validate the usability of the proposed approach. &copy; 2008 IEEE.

Abstract:Soil-water characteristics curve (SWCC) describes mainly the relationship of suction and
volumetric water content of nonsaturated soil; it is very important to research the fundamental properties of
SWCC. The relationship between SWCC and nonsaturated seepage curve has been studied based on theory
and experiment. The features of SWCC and of nonsaturated seepage curve are studied by natural
proportional rule; then the characteristics among SWCC and its differential curve, nonsaturated seepage
curve, grain distribution curve are researched in physics and mechanics; the scope of constant index of
SWCC and of nonsaturated seepage function is given; and their relationship is described. The experimental
results show that the SWCC is influenced by lots of factors, such as: material compositions, plastic index,
porous structure and stress state. The study of SWCC is very important to engineering construction.

Abstract:A math model for system reconstructing from tree shaped network to looped network is presented,
and a heuristic algorithm was developed to solve the optimal recovery orders of lines. The objective
function is to maximize power supply in each system state and to minimize total generation output
adjustment during recovery. The algorithm adopts reverse-direction searching strategy, that is firstly puts all
lines and loads to on state, then opens lines one by one till the original state of system is reached as the state
before reconstruction. Every time after opening one line, the optimal power flow algorithm was used to
solve generation and load adjustments. To guarantee recovered load would not be opened again, the amount
of load in each node could only be reduced. Two heuristic rules for selecting line-opening orders were
discussed. Based on the simulation results, an adapting strategy was presented. The algorithm was verified
by New England-39 systems and IEEE-30 systems in different original states.

Abstract:The research result of the sub-loading model is utilized to investigate the deformation and strength
behavior of over-consolidated soils by applying modified 3-D Cam Clay Model. In addition to the
conventional plastic volumetric strain, a state variable describing the deformation and strength of
over-consolidated soil is introduced to further improve the modified Cam Clay Model for investigating the
characteristics of over consolidated soil, and the evolution law of this variable is studied. The validity of the
improved modified 3-D Cam Clay Model is verified by the axial compression and extension test data for
soil with different over-consolidated ratio. The predicted dilatancy of over-consolidated soils is in good
agreement with the result of Nakai's sub-loading model.

Abstract:Since the traditional design method cannot obtain the global optimum performances for an active
vibration isolation system, this paper presents an approach to integrate structural and control parameters
optimization for the system via LMIs concurrent design. An example is given to illustrate the effectiveness
of the algorithm. A set of weight matrices of the cost function was obtained by large number of simulations.
The simulation results effectively demonstrate that the ultra-precision vibration isolation platform via LMIs
concurrent design has good isolation performance against the floor disturbance and the direct disturbance
over wide frequency range.

Abstract:A new objective image quality evaluation method is proposed based on DWT and HVS (Human
Visual System). The sensitivity of HVS is weighted with both subband and its energy. In order to verify the
reliability of WEWMSE method and to demonstrate the effectiveness, image quality evaluation
experiments based on the proposed method are performed on a set of images after JPEG and JPEG2000
compression. The results show that the assessment values of the proposed method are more agreed to MOS
(Mean Opinion Score) than those of the conventional method. &copy; 2008 IEEE.

Abstract:The paper discusses the stability of non-autonomous bidirectional associative memory neural
networks. The existence and uniqueness of periodic solutions of the neural networks are investigated by
using Gaines and Mawhin's continuation theorem of coincidence degree theory in the paper. Moreover,
criterions on asymptotic stability and exponential stability of periodic solutions of the neural networks are
obtained by using matrix function inequality, and algorithms for the criterions on the neural networks are
provided. Some of the results in the paper generalize and improve the results in the existing references. In
the end, an illustrate example is given to verify our results. &copy; 2007 Elsevier B.V. All rights reserved.

Abstract:Decreasing transport performance of GMPLS-Based OBS in network building was analyzed in the
worst case. Based on crosstalk characteristic of typical optical cross-connect, the impact of homodyne
crosstalk cascaded core nodes was derived and testified by simulating. The results show that crosstalk
accumulation of cascading core nodes is an important factor to decreases transport performance of
GMPLS-Based OBS network.

Abstract:This paper deals with the problem of optimization of finite-time observer for one kind of uncertain
linear discrete systems. Firstly, using the linear matrix inequality (LMI) method and the concept of
finite-time boundness, some sufficient conditions of finite-time boundedness for the linear discrete systems
with uncertain exogenous disturbance were derived. Based on them, the concept of finite-time observer for
the uncertain linear discrete system with state feedback and output was introduced. This concept can ensure
that the observer error is less than a given bound in a finite-time interval. Finally, the best design method
was developed. The method can be tested by numerical simulation.

Abstract:Multiple mobile agents with double integrator dynamics following a leader to achieve flocking
motion formation for switching topology were studied. Smooth adjacency matrix and smooth potential
function were introduced. Smooth controller design method for flocking motion of multiple agents is
proposed. The flocking stability was proved by existed theory of flocking of mobile agents and classical
Lyapunov theory. The control output of this scheme is smooth even as the agent network is switching and it
can make all the agents move with a flocking. Eventually, simulation example is given and the main result
is verified.

Abstract:In the underground repositories, the micro structure change of surrounding rock under the action
of the chemical corrosion will cause the increase of porosity in medium and the accelerative diffusion of
chemical contaminator. Aiming to analyze the chemical corrosion effect on the environment medium,
micro-local pattern and composition of sandstone specimens with size &phi;50 mm &times; 100 mm under
chemical corrosion of NaOH solution with pH value of 12 and concentration of 0.01 mol/L are tested using
SEM and X-ray technology firstly. After a series of laboratory tests on evolution of porosity of sandstone
specimens and pH value of solution at different periods under chemical corrosion of NaOH solution (0.01
mol/L, pH value is 12) are conducted; the microstructure change of sandstone under chemical corrosion is
analyzed from the view of porosity change. On the basis of the results of tests and the theory of chemical
thermodynamics, the corrosion mechanism is concluded for the dissolution of quartz matrix mineral and
siliceous cement. Then, based on the theory of chemical kinetics, chemical thermodynamics, and solute
transportation, a reactive-transport model for describing porosity change under chemical corrosion is
established. Finally, a simplified mathematic model is derived to describe microstructure change of rock
under chemical corrosion. And the numerical simulation is performed. The simulation result indicates that,
with the corrosion time increasing, the porosity increases firstly and then is driven to stabilization in the
end. The study results can be used as a valuable reference to understand the mechanism of the chemical
corrosion effect on the microstructure change of rock damage evolution, to set up the corresponding
damage constitutive model, and to offer an effective parameter for exactly estimating the safety and
stability of many rock engineering projects such as dam foundation, radioactive waste repositories, slope
and tunnel which are related to hydrochemistry.

Abstract:In recent three decades, several variants of the hypercube networks have been proposed to
enhance their performance and reliability. The so called enhanced hypercube networks (denoted by

investigated in detail. Based on the analysis of the properties and the performance of Q<inf>n, k</inf>, it is
shown that Q<inf>n, k</inf> has the minimum transmission delay of k - 1 + [n-k+1/2]. The one-to-one
routing process is also concerned, and it is proved that there exist n + 1 internally-disjoint paths between
any two distinct nodes in Q<inf>n, k</inf> Finally, The connectivity and edge-connectivity and Q<inf>n,

Abstract:In practise one is not only interested in system stability but also in bounds of system trajectories.
In such cases, finite-time stability plays an important role. In this note, finite-time stabilization of linear
systems with disturbances generated by an exosystem is considered. First, sufficient conditions for
finite-time stability is presented. Then, finite-time stabilization for linear systems via both state feedback
and output feedback are both considered. The sufficient conditions for the existence of such controllers can
be reduced to LMI feasible problem. Numerical examples show the effectiveness of the proposed method.

Abstract:The discrete-time uncertain nonlinear models are considered in a Takagi-Sugeno form and their
stabilization is studied through a nonquadratic Lyapunov function. The classical conditions consider a
one-sample variation, here, the main results are obtained considering k samples variation, i.e.,
&Delta;<inf>k</inf> V(x(t)) = V(x(t +k)) - V(x(t)). The results are shown to always include the classical
cases, and several examples illustrate the effectiveness of the approach. &copy; 2008 IEEE.

Abstract:This paper presents a modulized algorithm for computing 4<sup>M</sup>-point DFT, where M is
a positive integer. In the flow graph of the modulized algorithm, the 2<sup>P</sup>-point DFT blocks
replace the common butterfly computation networks in flow-graph of radix-4 FFT algorithms,where 2 &le;
P &le; 6. That is, the 4<sup>M</sup>-point DFT may be computed by the use of one 2<sup>P</sup>-point
DFT block. The block diagram and program structure of the modulized algorithm are simple. The total
number of computational requirements of the modulized algorithm is not bigger than those of radix-4 FFT.
Specially, when using a DSP processor integrated a 2P-point DFT block to compute 4 <sup>M</sup>-point
DFT, the speed of DFT will be faster than that of radix-4 FFT algorithm. Similarly, the modulized
algorithm may be refer to reference guide of design of the hardware block for computing
4<sup>M</sup>-point DFT. The modulized algorithm will be helpful to improve the DSP technology and
speed.

Abstract:In this paper, based on the Lyapunov stability analysis for functional differential equations, the
problems of global exponential stability and periodic solutions for a class of cellular neural networks with
time-varying delays and distributed delays are investigated. By constructing a new suitable Lyapunov
functional, some simple sufficient conditions ensuring existence, uniqueness, global exponential stability of
the equilibrium point and periodic oscillation of the networks are obtained, which are easy to check and
apply in practice. In addition, an example is also given to illustrate the effectiveness of the theory. &copy;

Abstract:An ultra-precision vibration isolation platform composes of a mechanical structure and a feedback
controller. Conventionally, these two elements are designed sequentially, with the controller design
subsequent to that of the mechanical structure design. The traditional design method cannot obtain the
global optimum performances for the system. This paper presents an approach to integrate structural and
control parameters optimization for an ultra-precision vibration isolation platform via LMIs concurrent
design. A set of weight matrices of the cost function is obtained by a large number of simulations. The
simulation results effectively demonstrate that the ultra-precision vibration isolation platform via LMIs
concurrent design has good isolation performance against the floor disturbance and the direct disturbance
over wide frequency range. &copy; 2008 IEEE.

Abstract:System splitting (SS) problem which is to determine proper splitting points (or called splitting
strategies) is very complicated in general, especially for large-scale power system, because a combinatorial
explosion of strategy space happens. So it is necessary to simplify the network before really starting solving
the problem. A new method of network simplification is presented based on 'principle of proximity', which
can further reduce scale of large power systems than current existed methods while keeping as many
feasible strategies as possible. Testing results on the IEEE 68-bus system and China north-east grid show
that proposed method is feasible and effective for reducing system scale and speeding up strategy searching
and verifying.

Abstract:A pseudo-parallel chaotic genetic algorithm is presented in this paper. The proposed algorithm is
established by using the pseudo-random property of chaotic sequence and putting chaos into a
pseudo-parallel genetic algorithm. The calculating results of three testing functions demonstrate that the
both of the premature phenomenon and the slow convergence in conventional standard genetic algorithm
can be prominently improved with the algorithm, and the presented algorithm is also superior to the
pseudo-parallel genetic algorithms in the aspect of avoiding premature. &copy; 2008 IEEE.

Abstract:The determination of effective elastic tensor is very important for civil engineering researchers;
and it is essential to calculate the effective elastic tensor in order to obtain the rational results. Four kinds of
methods for current effective elastic tensor determination are shown: volumetrical average method,
self-consist method, Hashin-Strikman method (upper limit method) and Hashin-Strikman method(lower
limit method) for every component in the effective elastic tensor. Based on the homogenization technology,
the formulae of macroscopic effective elastic tensor are obtained for stratified isotropic geomaterial under
the condition that the displacement and stress are equal in the everywhere in the element. And the proposed
equation can be simplified as the formulae of volumetrical average method and self-consist method under
some special cases. The comparative analyses of five different methods are performed; and the calculation
results show the proposed method can describe the parallel flow model and series flow model. The
upper-lower limit values of every component of effective elastic tensor are not determined by

Hashin-Strikman method; and the lower limit scope can be decided by self-consist method. However, the
upper limit scope can be determined by Hashin-Strikman method except C<inf>1133</inf><sup>eff</sup>.
The obtained results are very important for calculation and analysis of rock slope and dam foundation

Abstract:This paper presents a novel image segmentation method based on the integration of level set and
marker methods. The two distinct techniques for image processing are combined in a manner to utilize the
strengths of both. The internal markers obtained by extended-maxima transform bring a priori knowledge
to bear on the image segmentation. The initial level set function is constructed from region of interest (ROI)
on the internal markers. In this way, an automatic initialization of the level set evolution can be obtained,
and the boundaries of the objects can be extracted. The cost time does not depend on the size of the image
but the region of internal marker because only level set function with markers is updated instead of the
level set function for each pixel. Therefore, the consumed time is greatly reduced. The efficiency and
accuracy of the method are demonstrated by the experiments on the real blood vessel images and MR
image. &copy; 2008 IEEE.

Abstract:The normalized iris image was divided into eight sub-bands, and every column of each sub-band
was averaged by rows to generate eight 1D iris signals. Then the even symmetry item of 1D Gabor filter
was used to describe local characteristic blocks in 1D iris signals, and the results were quantified by their
polarities to generate iris codes. In order to estimate the performance of the presented method, an iris
recognition platform was produced and the Hamming distance between two iris codes was computed to
measure the dissimilarity of them. The experimental results in CASIA v1.0 and Bath iris image databases
show that the proposed iris feature extraction algorithm has a promising potential in iris recognition.

Abstract:The reaction conditions for the determination of bovine serum albumin (BSA) using
o-hydroxyphenylfluorone (o-HPF) as fluorescence probe reagent were studied. In the B-R medium at pH
7.90, o-HPF could react with BSA, producing a stable complex compound which resulted in fluorescent
quenching of this binary system. The quantitative assay was carried out based on the relation between the
degree of fluorescent quenching and the additional amount of BSA. The method has advantages of good
selectivity, stability and simplicity. The linear range of o-HPF fluorescence spectrophotometric method was
1.32-18.54&mu;g&middotmL<sup>-1</sup>. Moreover, the mechanism of the reaction BSA and o-HPF
was discussed, and the quenching constant, and the thermodynamics constant of the fluorescence effects
were calculated. The results showed that the nonconvalent binding forces were the binding force between
o-HPF and BSA, and the quenching of BSA to o-HPF was probably a single static quenching process.

Abstract:The performance of an optical code division multiplexing access (OCDMA) system employing
the differential phase shift keying (DPSK) data format and turbo code is investigated and simulated. A
bandwidth-limited coherent time spreading (TS) OCDMA system is considered. Theoretical results show
that performance degradation due to bandwidth limitation could be effectively restrained by the application
of the DPSK data format in a coherent OCDMA system, and further performance improvement could be
achieved by incorporating turbo coding into the OCDMA system. &copy; 2008 Springer Science+Business

Abstract:In this paper the relaxed stability conditions and the design of stabilization controller for discrete
Takagi-Sugeno fuzzy time-delay model are considered through a new approach using specific Lyapunov's
functions. Firstly, we give some relaxed sufficient conditions for stability of discrete T-S time-delay model
via LMIs. Secondly, we consider the problems of stabilization for such models in two different cases,
whether the time-delay is known or unknown. All the presented results outperform previous ones found in
the literature and several examples are presented to illustrate the effectiveness of the method. &copy; 2008

Abstract:The paper addresses the noise image which adopts the embedded zerotree wavelet coding
algorithm to compress and then results in decreasing the amount of the zerotree and increasing the amount
of the alone-zero, which will affect the compression effect. Therefore this paper brings forward the
characteristic directional median filter to reduce noise before the noise image compression; aim at solving
the insufficiency of the scope table order frequent adjusts in the EZW algorithm, we proposes to adopt
adaptive depth first search strategy through definition floating threshold. The result shows that the new
image compression scheme has improved better than traditional EZW algorithm in the aspects of image
quality, compression effect and compression coding efficiency.

Abstract:Topology selection plays a key important role in the design of computer network because it
decides many crucial features and consequently has overwhelming impact on the network's performance
Among the choice of network topologies the hypercube Q<inf>n</inf> is popular because of it nice
properties Recentl a more efficient network called enhanced hypercub network (denoted by
Q<inf>n,k</inf>) has been proposed to enhance the performance and reliability of hypercube. Howevei
despite a lot of advantages discovered many important properties of enhanced hype rcube networks still
remains unknown, which prevents the further applications of enhanced hypercube networks in critical areas.
This paper aims to discover some important unknown features of enhanced hypercube networks through
the topology property analysis. For this purpose, the structural natures of Q<inf>n,k</inf> are investigated
in detail. The properties related to cycles embedding into Q<inf>n,k</inf> have been investigated. It is
obtained that Q<inf>n,k</inf> is bipartite if and only if n and k have same parity. We also obtained that if n
and k have same parity, then every edge of Q<inf>n,k</inf> lies on a cycle of every even length from 4 to

Abstract:The first impoundment of the Three Gorges Dam reservoir in China started from a water surface
elevation of 95 m on June 1, 2003 and reached 135 m on June 15, 2003. Shortly after the water level
reached 135 m, many slopes began to deform and some landslides occurred. The Qianjiangping landslide is
the largest one; it occurred on the early morning of July 14, 2003 and caused great loss of lives and
property. Field investigation revealed that, although failure occurred after the reservoir reached 135 m, the
stability of the slope was already reduced by preexisting sheared bedding planes. To study the mechanism
of the rapid motion of this reactivated landslide, two soil samples were taken from a yellow clay layer and a
black silt layer in the sliding zone, respectively, and a series of ring shear tests were conducted on the
samples. One series of ring shear tests simulates the creep deformation behavior, while the other series
simulates different shear rates. Conclusions drawn from analysis of the ring shear tests indicate that the
mechanism of the rapid motion of the reactivated landslide was caused by the rate effect of the black silt
layer during the motion phase after the creep failure. The yellow clay layer did not play any important role
in the rapid motion in the 2003 event. &copy; 2008 Springer-Verlag.

Abstract:Active contour method is a powerful approach for object contour extraction. This paper presents a
new object contour extraction method, which combines the level set evolution with the support value filter.
It analyzes image under the least squares support vector machine (LS-SVM) framework and uses the
support values to represent salient features underlying image. The Gaussian filter, used in conventional
level set method to compute the edge indicator, is replaced by the support value filter deduced from the
mapped LS-SVM. The level set evolution method is implemented on the feature image obtained by
convolving the support value filter with the original image. Experiments are undertaken on the synthetic
and real images. The experimental results demonstrate that the support value filter can provide a good
estimate for the optimal step size in a gradient descent algorithm and the proposed method has advantages
over the direct level set evolution method in converging speed and contour extraction accuracy. &copy;

Abstract:Trajectory sensitivities complement time domain simulation in the analysis of large disturbance
dynamic behavior of the simulation model of power system. Because of hydroelectric systems is a
nonlinear non-smooth dynamics of complex systems, sometimes it is very difficult to meet the need by
using the linear approximation for the dynamic simulation analysis, it also needs to use Taylor series of the
second-order. This paper presents the applications of second-order sensitivity as an extension to the
established linear sensitivity approach on the hydro-power plant simulation. Second-order sensitivity and
first sensitivity are used in the time-domain simulation analysis for the effect of controllers on hydroelectric
systems dynamics. A comparison between the two approaches in terms of accuracy is carried out, and the
results show that the proposed method improves the accuracy of trajectory by roughly one order sensitivity.

Abstract:According to different statistical approaches, a stochastic process of pseudo-wind displacement
was defined which is equivalent to Davenport's power spectrum. Utilizing the basic principle of the
Karhunen-Loeve decomposition for stochastic processes, the orthogonal expansion of the pseudo-wind
displacement was carried out and a series expression of the wind velocity fluctuations can be obtained
accordingly. From this expression, the main probabilistic characteristics of the wind velocity fluctuations
may be captured with only a few random variables, and therefore a foundation for the dynamic response
analysis and reliability assessment of wind-excited buildings may be established. The accuracy and
effectiveness of this orthogonal expansion approach is demonstrated by the close match of the obtained
sampling power spectrum to Davenport's spectrum.

Abstract:Hydroxyapatite (HA) was incorporated into polyvinyl alcohol hydrogel (PVA-H) to form a
bioactive composite for applications as artificial cartilage. HA/PVA-H composite containing 2 and 5 wt.%
of HA was made for in vitro evaluation. Immersion tests in vitro were performed with PVA-H and
HA/PVA-H specimens. XRD, FTIR and SEM were used to characterize the structure and component of
specimens. SEM results showed that apatite formed within a short period on HA/PVA-H composite after its
immersion in SBF, demonstrating high in vitro bioactivity of the composite. Characteristic peaks of
PO<inf>4</inf><sup>3-</sup> were enhanced, and new peaks of CO<inf>3</inf><sup>2-</sup> were
found after immersion on the FTIR experiments. These results proved that the crystalloid deposition on the
surface of HA/PVA-H were bone-like apatite. It also found that the precipitation of apatite increased with
increase in HA content of the composites, as well as with increasing immersion time for the composite.
Mechanical study revealed that the elastic modulus of HA/PVA-H composite increased initially with
immersion time in SBF, due to apatite formation on composite surface and kept constant after prolonged
immersion in SBF. &copy; 2007 Elsevier B.V. All rights reserved.

Abstract:In this article, the local anomalistic blocks such as crypts, furrows, and so on in the iris are
initially used directly as iris features. A novel image segmentation method based on intersecting cortical
model (ICM) neural network was introduced to segment these anomalistic blocks. First, the normalized iris
image was put into ICM neural network after enhancement. Second, the iris features were segmented out
perfectly and were output in binary image type by the ICM neural network. Finally, the fourth output pulse
image produced by ICM neural network was chosen as the iris code for the convenience of real time
processing. To estimate the performance of the presented method, an iris recognition platform was
produced and the Hamming Distance between two iris codes was computed to measure the dissimilarity
between them. The experimental results in CASIA v1.0 and Bath iris image databases show that the
proposed iris feature extraction algorithm has promising potential in iris recognition. &copy; 2008 The

Abstract:Mammography is one of the most efficient imaging techniques for the early detection and
diagnosis of breast cancer in woman. The appearance of microcalcifications (MCs) in X-ray mammograms
can be regarded as important early diagnostic feature of breast cancer. However, the detection of MCs in
X-ray mammograms only depend on radiologists by visual inspection is a difficult task. In this paper, a
novel algorithm for the automated detection of MCs in digital mammograms is described. The aim of
approach is to locate suspicious MCs by analyzing the distribution of brightness over the digital
mammograms. The algorithm for the detection of MCs is performed in two steps. First, the digital X-ray
mammogram intensity surface is well-fitted by the least squares support vector machines (LS-SVM), and
then the maximum extremum points are detected on the fitted intensity surface by convolving the image

with the second order directional derivative operators deduced from the mapped LS-SVM with mixture of
kernels. The proposed approach is developed and evaluated by using MIAS database. The experimental
results demonstrate the possible MCs are detected accurately and efficiently. &copy; 2008 IEEE.

Abstract:The stress distributed in the mid-bondline of the joints made of aluminium alloy and an epoxy
adhesive was determined with the ANSYS software. The results from the FEA showed that the values of
the peak stresses of the all the stress components (including the longitudinal stress Sx, the peel stress Sy,
the shear stress Sxy, the 1st principal stress S1 and the von Mises equivalent stress Seqv) distributed in the
mid-bondline are changed a little as the notch distance L was increased while the notch depth d was not
great than 0.6mm. But the evidently changes occurred when the notch depth d was great than 0.9 mm for
the stress Sx, Sy and S1 distributed in both the mid-bondline and the interface of me lap zone. When taken
the stress distributed in the middle part of the lap zone into account, the peak stress at the point in the
mid-bondline corresponding to the edge of the notch decreased firstly and then increased again as the notch
distance L was increased from 0 mm to 8 mm. The proper geometry of the notch in the specimen was
chosen by finite element analysis.

Abstract:A numerical simulation is proposed to study the dynamics expansion characteristics during the
material irradiated by a high-intensity laser beam.The ionization effect and the local mass and momentum
conservations for plasma expansion are considered in this model. As an example of carbon target, the
plasma flow dynamics into a vacuum, like ionization degree, plasma number density and space pressure are
studied in detail. The results show the plasma temperature strongly affects the ionization fraction and the
ionization effect evidently influences the plasma dynamic expansion behavior. The space pressure of
plasma decreases along with the plasma expansion.

Abstract:Tracking a leader agent by swarm was studied. A class of hybrid control laws for swarm was
proposed to make the motion states of all agents in the swarm asymptotically converge to the time variant
reference trajectory. The interaction or communication relationship among agents was modeled by graph
theory. Based on non-uniform swarm, a dynamic model in directed networks was constructed. The stability
was analyzed by using matrix analysis and classical control theory. The main conclusions that the tracking
error of the whole system would converge to zero asymptotically were proved theoretically. The simulation
examples were also given, showing that the swarm could track a dynamic trajectory and reach a rendezvous
respectively.

Abstract:The inelasticity and ununiformity of the plasma-particles induced by pulsed laser ejecting were
considered. The effect of particles collision of particles on velocity and space number density was studied
using molecular dynamics (MD) method based on the fraction theory. The results show in two conditions
namely even mass and uneven mass distribution, the velocity and plasma number density all deviate initial
distribution because of energy dissipation; in the condition of mass for fraction distribution, the deviation is
more remarkable; the whole particles density showed an interior dense outer attenuate fusiform profile.
These results of the particles action based on the proposed fractal and inelasticity model are found to be in
agreement with the experimental observation.

Abstract:The optically induced grating enhanced by dc electric field in nematic liquid crystal (LC) doped
with copper porphyrin is studied. The reorientational effect of the LC was not observed for the writing
beams with the intensity up to 500 mW/ mm2, but the threshold of the reorientation was reduced to 1 mW/
mm2 with the assistance of an electric pulse applied to the LC. The low threshold for the induced grating
can be retained even after switching off the dc pulse, indicating that an induced field inside the LC is
present to sustain the low threshold operation for the induced grating. The low threshold operation does not
persist by short circuiting of LC electrodes. The underlying mechanism is explained by an optical
surface-charge mediated effect. &copy; 2008 American Institute of Physics.

Abstract:The results of drained shear tests carried out on calcareous sand sample from the South China Sea
were presented. The tests reveal that the relation between the stress and strain changes when the confining
pressures are changed. Under low pressure, it is similar to the terrigenous sand; and under the medium
confining pressure, the mechanical property of the calcareous sand is just analogous with that of the
terrigenous sand under high stress level. The particle breakage results in liberation of the close interspace.
Thus the volume of strain is much larger than that of quartz sand, which makes almost all the deformation
irreversibly plastic during shear process. And the results also indicate that the dilatancy and ratio of stress
are closely related to the confining pressures, they decrease as the confining pressures increase.

Abstract:A modified sol-gel method was used to fabricate (Pb<inf>0.25</inf>Ba<inf>x</inf>
Sr<inf>0.75-x</inf>)TiO<inf>3</inf> (PBST) thin films with x = 0.05,0.1,0.15 and 0.2 on
Pt/TiO<inf>2</inf>/SiO<inf>2</inf>/Si substrate. The structure, surface morphology, dielectric and
tunable properties of PBST thin films were investigated as a function of barium content (x). X-ray
diffraction and scanning electron microscopy analysis showed that we could get pure PBST perovskite
phase and relative fine density thin films with smooth surface. It was found that the crystal lattice constant,
grain size, room temperature dielectric constant, dielectric loss and tunability of Ba solutionizing PST thin
films
increased
with
the
increase
in
Ba
content.
For
(Pb<inf>0.25</inf>Ba<inf>0.2</inf>Sr<inf>0.55</inf>)TiO<inf>3</inf> thin film, it had the highest
dielectric constant of 1390 and the largest tunability of 80.6%. The figure of merit parameter reached a
maximal
value
of
28.9
corresponding
to
the
(Pb<inf>0.25</inf>Ba<inf>0.05</inf>

Abstract:The 0-1 knapsack problem (KP) is one of the classical NP-hard problems with binary decision
variables. The traditional differential evolution (DE) is an effective stochastic parallel search evolutionary
algorithm for global optimization based on real valued crossover and mutation operations in continuous
space. To solve KPs, based on DE, a discrete binary version of differential evolution(DBDE) was
introduced, where each component of a mutated vector component changes with the probability and will
take on a zero or one value. The approach was implemented to 4 cases. By comparisons with the results of
the discrete binary version of particle swarm optimization (DPSO), DBDE outperformed DPSO for all the
cases with better solutions and more rapid convergence speed. &copy; 2008 IEEE.

Abstract:Ti(C, N)-based cermets were produced by vacuum sintering. The effect of sintering temperature
and holding time on the microstructure and mechanical properties of Ti(C, N)-based cermets was studied,
and the fracture morphology was investigated by scanning electron microscope. The results show that, with
the increasing of the sintering temperature, the microstructure of cermets became uniformity, and the
ceramic grains got rounded, and the rim phase structure was completeness gradually. When the sintering
temperature was too high or the holding time was too long, the rim phase was modified thicken, and the
growing phenomenon of grains was obvious, the properties was decreased. The cermets sintered at
1440&deg;C for 60 min showed the best mechanical properties. Their transverse rupture strength reached
1914.2 MPa, and the hardness reached 90.1.

Abstract:To alleviate the influence of gas compressibility on the process performance of time-pressure
dispensing for electronics encapsulation, a predictive model is developed based on power-law fluid to
estimate the encapsulant amount dispensed. Based on the simple and effective model, a run by run (RbR)
supervisory control scheme is delivered to compensate the variation resulting from gas volume change in
the syringe. Both simulation and experiment have shown that the dispensing consistency has been greatly
improved with the model-based RbR control strategy developed in this paper. &copy; 2008 Institute of

Abstract:The panchromatic (Pan) sharpening of multispectral (MS) bands is an important technique in the
various applications of satellite remote sensing. This paper presents an MS Pansharpening method using the
proposed multiscale mapped least-squares support vector machine (LS-SVM). Under the LS-SVM
framework, the salient features underlying the image are represented by support values, and the support
value transform (SVT) is developed for image information extraction. The low-resolution MS bands are
resampled to the fine scale of the Pan image and sharpened by injecting the detailed features extracted from
the high-resolution Pan image. The support value analysis is implemented by using a series of multiscale
support value filters that are deduced from the mapped LS-SVM with multiscale Gaussian radial basis
function kernels. Experiments are carried out on very high resolution QuickBird MS + Pan data. Fusion
simulations on spatially degraded data, whose original MS bands are available for reference, show that the
proposed MS Pan-sharpening method performs comparable to the state-of-the-art in terms of the pertained
quantitative quality evaluation indexes, such as the Spectral Angle Mapper, relative dimensionless global
error in synthesis (ERGAS), modulation-transfer-function-based tool and quality index (Q4), etc. The SVT
is an effective tool for remote sensing image fusion. &copy; 2008 IEEE.

Abstract:In this note, the global asymptotic stability for delayed recurrent neural networks is addressed with
a new Lyapunov-Krasovskii function. New delay-independent linear matrix inequality (LMI)-based
conditions for global asymptotic stability are derived. A key feature of the new approach is the introduction
auxiliary matrices, which can provide useful and less conservative results. This feature also enables us to
cast a series of previous LMI-based results into even more general framework, logic flow of ideas and
comparisons are thus easily shown. Three numerical examples show the effectiveness of the proposed
method. &copy; 2008 IEEE.

Abstract:The effect of vanadium carbide (VC) addition on the sinterability and the microstructure of
ultrafine Ti(C, N)-based cermets consolidated through spark plasma sintering (SPS) was systematically
investigated using optical microscope, scanning electron microscope (SEM) with X-ray energy dispersive
spectrometer (EDS), X-ray diffractometer (XRD) and transmission electron microscope (TEM). Our results
reveal that the addition of VC increases the porosity of sintering body and depresses the sinterability of
Ti(C, N)-based cermets. It is also found that the VC addition has a significant influence on the
microstructure of ultrafine Ti(C, N)-based cermets, which inhibits the dissolution of titanium-containing
compounds and the formation of inner rim phase and outer rim phase, thus preventing from grain growth.
Owing to the depressed dissolution and precipitation, nitrogen liberation is mitigated, therefore resulting in
less amount of graphite phase in the samples. In substance, VC changes the solubility of metallic elements
in the binder, which makes more elements of Mo and W to be reserved in the binder and thus greatly
decreases the content of titanium dissolved into the binder. The re-building solubility rule determines the
development of phases and microstructure. &copy; 2007 Elsevier B.V. All rights reserved.

Abstract:The paper discusses the black-start capability of different types of CCPPs and the feasibility to use
them as black start units. The black starting of a 150 MW CCPP unit and a 300 MW steam unit is simulated.
Simulink is used to calculate the excitation inrush currents associated with the transformer energisation,
considering the saturation effects and the three-phase unbalance. The dynamic processes of starting large
asynchronous motors and load pickup in an isolated system are calculated by EDSA. Based on the
simulation results, the paper proposes countermeasures to improve the feasibility of black-start by CCPP.
The models can be applied to the formulation of restoration plans and field testing.

Abstract:An efficient method is developed for orthogonal expansion of wind stochastic fields. The
procedure starts by decomposing the wind stochastic field into a product of a stochastic process and a
random field, which represent, respectively, the temporal property and the spatial correlation property of
the wind stochastic field. The stochastic process for wind velocity fluctuations may be represented as a
finite sum of deterministic time functions with the corresponding uncorrelated random coefficients from
orthogonal expansion. Similarly, the random field may be expressed as a combination form with only a few
random variables by using the Karhunen-Loeve decomposition. A numerical example is provided to
demonstrate the accuracy and effectiveness of the procedure.

Abstract:Finite-time stability can be used in all applications where large values of the state are not
acceptable. In this paper, we extend the concept of finite-time boundedness (FTB) for a class of linear
discrete-time systems with time delay and time varying exogenous disturbances. Then, we present a new
approach for finite-time control problems for these discrete-time systems. The main results provided are
sufficient conditions for robust finite-time stabilization via state feedback. The conditions can be reduced to
a feasibility problem involving linear matrix inequalities (LMIs). Finally, an illustrative example is given to
demonstrate the validity of the proposed methodology.

Abstract:In many spatial analyses and visualizations related to terrain, a high resolution and accurate digital
surface model (DSM) is essential. To develop a robust interpolation and smoothing solutions for airborne
light detection and ranging (LIDAR) point clouds, we introduce the weighted adaptive mapping LS-SVM
to fit the LIDAR data. The SVM and the weighted LS-SVM are introduced to generate DSM for the
sub-region in the original LIDAR data, and the generated DSM for this region is optimized using the points
located within this region and additional points from its neighborhood. The fitting results are adaptively
optimized by the local standard deviation and the global standard deviation, which decide whether the
SVM or the weighted LS-SVM is applied to fit the sub-region. The smooth fitting results on synthesis and
actual LIDAR data set demonstrate that the proposed smooth fitting method is superior to the standard
SVM and the weighted LS-SVM in robustness and accuracy. &copy; 2008 SPIE.

Abstract:A new topology optimization method for designing thermomechanical compliant actuators using
meshless methods is presented. The meshless method is employed to discretize the design domain and the
bulk density field, which can avoid the undesirable mesh distortion when the standard finite element
method (FEM) is applied. The method for imposing boundary conditions in the meshless method is
discussed in details. An interpolation scheme is applied to indicate the dependence of material mechanical
and thermal properties on pseudo-densities which are distributed to the related integration points.
Furthermore, the design sensitivity analysis is performed by incorporating the adjoint approach into the
meshless method. The optimization problem is then solved by the method of moving asymptotes (MM A).
The availability of the proposed method is demonstrated by using a widely studied compliant structure.

Abstract:The coupling analysis of slope runoff and infiltration under rainfall is one of the important key
problems for the research of rainfall-induced landslides and the soil conservation. The subsurface and
surface flow coupling equation is established; and the solution can be achieved directly by the method of
FEM. Using the method, it is not necessary to calculate the moisture flux that passes the slope surface; and
then the computational precision and the computational speed can be improved. The simulation results
show that the method is feasible, efficient and stable in calculation.

Abstract:In this paper, stabilization problems for a particular class of non linear continuous model with
time-delays in the form of Takagi-Sugeno(TS) are investigated. The considered models are of multiple
time-delays in state. Some new sufficient conditions for stability and stabilizability are given. They are
based on some PDC control laws and some matrix translation properties. First of all, we derive stability
conditions of unforced and forced system of considering model, respectively. We then discuss stabilization
problem with two cases: (i) unknown delays and (ii) known delays, and give stabilization conditions via
LMI. All given conditions are in the form of LMI's and it's easy to be checked by means of MATLAB.

Abstract:A passive polarization beam splitter in silicon-on-insulator (SOI) waveguides, which consists of
two 3-dB multimode interference (MMI) couplers and two Mach-Zehnder interferometer (MZI) arms with
the same length but different rib widths, has been proposed recently and a numerical method of design is
needed because the analytical solution for this 3-dimensional (3D) SOI waveguides is difficult to achieve.
The scalar finite difference beam propagation method (FD-BPM) is used to design the 3-dB MMI couplers
and the positions of the input or output waveguides and the length of multimode waveguide are determined.
In our design, the length of MMI couplers is 1228 micron when the width of rib is 36 micron. The
propagation constants of TE-polarized and TM-polarized mode supported by 3D rib waveguides on SOI are
calculated by the Semi-vector FD-BPM which is polarization related. From these data obtained for different
rib widths (from 2.0 micron to 4.0 micron), the appropriate length of MZI arms is selected. In our example,
the widths of two arms are 3.4 micron and 2.0 micron respectively and the length of arms is 1506 micron.
The TE-polarized light and TM-polarized light are input to the splitter separately and the Semi-vector
FD-BPM is used to check the design.

Abstract:This paper is concerned with the adaptive robust convergence for a class of neural networks with
time-varying delays. By employing the Lyapunov method and a novel lemma, some delay-independent
conditions are derived to guarantee the state variables of the discussed time-varying robust system to
converge, globally, uniformly, exponentially to a ball in the state space with a pre-specified convergence
rate. Here, the existence and uniqueness of the equilibrium point needs not to be considered. Finally, an
illustrated example is given to show the effectiveness and usefulness of the results. &copy; 2007 Elsevier

Abstract:Non-ionic surfactant vesicles (NSVs), also referred to as niosomes, have been studied as an
alternative to conventional liposomes. In this paper, electrochemical inspection of the interaction between
Herring sperm DNA and niosomes has been investigated after a simple and novel method for the formation
of niosomes on Au electrode. Each step of electrode modification has been confirmed with cyclic
voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The assembly of octadecanethiol
(ODT) layer on the electrode surface generates a packed film that introduces a barrier to the interfacial
electron transfer (R<inf>et</inf>), and the subsequent immobilization of niosomes onto the self-assembled
monolayer (SAM) layer results in a further increase of R<inf>et</inf>, due to the formed bilayer almost

blocked the redox probe to the electrode surface. When Herring sperm DNA was added, the R<inf>et</inf>
value decreased, indicating that the barrier of the redox probe to the surface was disrupted. The addition of
DNA caused the formation of some transmembrane channels for the redox probe across the niosomes. A
good linear relationship between R<inf>et</inf> value and DNA concentration was found over the 0-0.05
mg mL<sup>-1</sup> concentration range. &copy; 2008 Elsevier B.V. All rights reserved.

Abstract:As a potential artificial cartilage material, the friction and wear properties of nano-hydroxy apatite
(HA) particles filled poly (vinyl alcohol) hydrogel (PVA-H) composites sliding against stainless steel disk
under water lubrication condition were studied by using a four ball tester. The worn surfaces were
investigated by using a scanning electron microscope (SEM) to determine the wear mechanisms.
Experimental results show that filling HA to PVA-H will slightly increase the friction coefficient of
composites with the increasing of HA content under water lubrication condition. Meanwhile, HA particles
can greatly reduce the wear mass loss of the PVA-H composites and enhance the load carrying capacity, the
wear loss of the 1 wt% HA reinforced PVA-H composites can be decreased by 30 percent under 2.0 MPa to

50 percent under 0.5 MPa contact pressure. We also found that 2 wt% HA content of composites increase
the wear mass loss under the same condition. SEM examination shows that the worn surface of low HA
containing (1 wt%) composites are much smoother than that of pure PVA-H or high HA containing (2 wt%)
composites under 1.5 MPa contact pressure. It is also found that there are big hole and big reunited HA
particles in the surface of 2 wt% HA containing composites, which leads to deterioration of the surface of
samples under higher loads in water lubrication. These results may be useful in the tribological design of
artificial articular cartilage material. &copy; 2008 Wuhan University of Technology and Springer-Verlag

Abstract:Surface-enhanced Raman scattering (SERS) integrates high levels of sensitivity with
spectroscopic precision, and thus, has tremendous potential for chemical and biomolecular sensing. The
key to the wider application of Raman spectroscopy using roughened metallic surfaces is the development
of highly enhancing substrates for analytical purposes, i.e., for better detection sensitivity of trace
contaminants and pollutants. Here, we have prepared Au, Ag, AuAg multilayer, and [email protected] films on glass
substrates for SERS-active substrates. The [email protected] film shows a much stronger SERS signal for
trans-bis(4-pyridyl)ethylene (BPE) molecules than those from pure Au, Ag, and AuAg films, indicating the
[email protected] film is more powerful than pure Au, Ag, and AuAg film as SERS active substrates. The enhanced
surface Raman scattering signals were attributed to the local field enhancement in the core-shell structure.

Abstract:A water-soluble polysaccharide named as HPS-1 was isolated from the roots of Hedysarum
polybotrys Hand.-Mazz by hot water extraction, anion-exchange and gel-permeation chromatography and
tested for its anti-tumor activity. Its structural characteristics were investigated by FTIR, HPLC, NMR
spectroscopy, GLC-MS, methylation analysis, periodate oxidation and Smith degradation. Based on the
data obtained, HPS-1 was found to be an &alpha;-(1 &rarr 4)-d-glucan, with a single &alpha;-d-glucose at
the C-6 position every nine residue, on average, along the main chain. The glucan has a weight-average
molecular weight of about 9.4 &times; 10<sup>4</sup> Da. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl
tetrazolium bromide (MTT) assay revealed that HPS-1 significantly inhibited the proliferation of human
hepatocellular carcinoma HEP-G2 cells and human gastric cancer MGC-803 cells in vitro, indicating
HPS-1 could have a possible cancer therapeutic potential. &copy; 2008 Elsevier Ltd. All rights reserved.

Abstract:In order to prolong the lifetime of wireless sensor networks, this paper presents a multihop routing
protocol with unequal clustering (MRPUC). On the one hand, cluster heads deliver the data to the base
station with relay to reduce energy consumption. On the other hand, MRPUC uses many measures to
balance the energy of nodes. First, it selects the nodes with more residual energy as cluster heads, and
clusters closer to the base station have smaller sizes to preserve some energy during intra-cluster
communication for inter-cluster packets forwarding. Second, when regular nodes join clusters, they
consider not only the distance to cluster heads but also the residual energy of cluster heads. Third, cluster
heads choose those nodes as relay nodes, which have minimum energy consumption for forwarding and
maximum residual energy to avoid dying earlier. Simulation results show that MRPUC performs much
better than similar protocols. &copy; 2008 IEEE.

Abstract:By means of testing the shear strength with single lap joint, measuring electrical resistivity for
cured products and the curing strain with strain gauges, the effect of cure parameters on the properties of
HT1012 conductive adhesive filled with copper powder was investigated, and the residual stress in the
conductive adhesives was also estimated. The experimental results show that the properties such as shear
strength of the adhesives, electrical resistivity of products as well as the residual stress of cured HT1012
copper-filled conductive adhesive were evidently affected by curing temperature and time. The diagrams of
scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) were also used to determine
the properties. The higher mechanical property was achieved under the condition of curing the adhesive 3 h
at 60 &deg;C as the density of the hydrogen links or linkages existed in the adhesive was relatively higher
and the lower electrical resistivity occurred at 80 &deg;C. &copy; 2008 Wuhan University of Technology

Abstract:This paper treats the chaotic synchronization problem for Rikitake chaotic systems via
unidirectional coupling with partial systems states. Two control approaches, namely the self coupling of
single state variable and nonlinear feedback controller with partial systems states, are investigated. Based
on the Lyapunov stability technique, control laws based on single variable of driven system are derived
such that the two identical Rikitake chaotic systems are asymptotically synchronized, where the control
scheme doesn't need additional energy and it just relies on the self coupling of single state variable of the
chaotic systems. Meanwhile, the complete synchronization for two identical Rikitake chaotic systems by
feedback control laws with partial systems states is also derived using the conditions of asymptotical
stability and exponential stability. Finally, numerical experimental results of two synchronized Rikitake
chaotic systems are presented. &copy; 2008 IEEE.

Abstract:There are many approximately horizontal slip surface landslides in Jurassic red strata in Wanzhou
city of the Three Gorges Reservoir area. However, the formation mechanisms of these landslides are not
clear. In order to explore the mechanism of these landslides, triaxial stress relaxation experiments with
GDS unsaturated triaxial testing systems are carried out to investigate the stress relaxation properties of the
sliding zone soil of Anlesi landslide. Test results show that the stress relaxation speed changes linearly with
initial strain variation. However, it is independent of confining pressure. The soil volume changes little; and
it can almost be ignored during the relaxation tests. Based on the stress relaxation tests, a new constitutive
model for the stress-strain-time behavior of the sliding zone clay is introduced by assuming a hyperbolic
stress-strain relationship and a logarithmic time-tress relationship. The comparison between the rheological
model and experimental results reveals that the new rheological model presents the relaxation
characteristics of the sliding zone clay nicely. And that also provides the model and parameters for the
further researches on approximately horizontal slip surface landslides existing in Jurassic red strata in the
Three Gorges Reservoir area. The new relaxation model indicates that the shear stress of the sliding zone
clay will decrease to zero. The result is significant for researching and controlling the approximately
horizontal slip surface landslides.

Abstract:Many approximately horizontal slip surface landslides are found in Jurassic red strata in Wanzhou
of the Three Gorges Reservoir area. However, the formation mechanism of these landslides is not clear. In
order to discover the causes of these landslides, experiments on rheological behaviors were performed on
the sandstone of Erchengyan landslide bedrock in Wanzhou with triaxial creep test machine RLM-2000.
Before the specimen failure, there is an accelerated creep stage, which lasts for about 8 h; this course is
similar to the failure of deformation of some approximately horizontal slip surface landslides. Tautochrone
of test data indicates this kind of rock is close to linear viscoelasto-plastic materials. Burgers model is used
to fit the curves; and the three-dimensional constitutive relationship of Burgers model and its parameters
are obtained. The results show that the proposed rheological Burgers model can exactly express the
rheological characteristics of Jurassic red strata in Wanzhou. It can also describe the mechanism of the
approximately horizontal slip surface landslides occurring in Jurassic red strata in Wanzhou. There is a
nearly linear relationship between the creep strain rate and time in the beginning of accelerative creep stage.
And the creep strain rate behaves closely to exponential growth with time in the last stage of accelerative
creep. The accelerative creep shows highly nonlinear characteristics; and the creep strain rate displays a
discontinuous form, which occurs in jumps change. Furthermore, the experimental results reveal the
long-term strength of the rock is only 44 percent of the peak strength in triaxial tests. This conclusion is
very helpful for the research on the mechanism and prevention of the horizontal slip surface landslides.

Abstract:There are few CFRDs built on thick alluvium deposits with dam height of more than 50 m. So do
the relative design and construction experience. The 50.8 m-high Dahe CFRD built on 20-37 m-thick
alluvium deposits is now in the preliminary design phase. Its right face slab 41.7 m in height is
perpendicularly connected with the right bank of a mountain and the left toe slab 15.3 m in height is
perpendicularly connected with the left bank of another mountain. Such topographic characteristics of
mountain body and the relative design scheme are apparently different from those of other CFRDs built on
thick alluvium deposits. Since the excessive deformation of perimetric joint would lead to failure of seal
materials and cause water leakage, 3D finite element stress-deformation analysis was carried out. 3D finite
element mesh with 19250 elements including surrounding mountain and thick alluvium deposits was
established by use of advanced grid discreteness technique. Large scales of equations solving method were
adopted in the procedure and the computer calculation time was greatly reduced from 40 hours to 20
minutes. Therefore the behavior of the dam and the joint of seepage prevention system was obtained in a
short time, and the results would be helpful to the design of Dahe CFRD.

Abstract:A study was conducted for qualitative analysis of the finite element slope stability failure based on
the elastic-perfectly plastic model. The study found that when a slope arrives at the critical state, there
exists a band in which all elements will be in the plastic state and the band will go through the slope from
the toe to the top. The study observed that the elasto-plastic matrix is positive definite for hardening
materials, positive semidefinite for elastic-perfectly plastic materials, and indefinite for softening materials.
The study also observed that the displacement interpolation pattern associated with isoparametric elements

can resist the formation of the shear band and produce an element to transfer the excess load in isotropy

Abstract:Time-cost optimization problem is one of the most important aspects of construction project
planning and control. Construction planners must select appropriate resources, including crew size,
equipment, methods and technologies to perform tasks of a construction project. In general, there is a
trade-off between time and cost to complete a task; the less expensive the resources, the long it takes. Such
problems are difficult to solve because they do not have unique solutions. Especially for large construction
projects, the current research on project duration optimization cannot meet the growing demands because it
is so complicated and there are so many uncertain problems in it. On the basis of Critical Path Method
(CPM), this paper analyzed the relationship between time and cost, established time-cost optimization

Abstract:Agent-oriented design is one of the most active areas in the field of deployment of web-based
distance education, and test is a popular measurement tool of learners' knowledge in order to verify the
learner's level of understanding and select corresponding educational strategy. In this paper, an innovative
approach to seamless integration of the particle swarm optimization (PSO) and multi-agent system (MAS)
is proposed. In order to generate a test paper automatically, a modified genetic particle swarm optimization
(GPSO) is presented, in which the values of parameters will be decreased linearly with the number of
iterations for improving the late convergence rate. For the implementation of GPSO based on multi-agent
system, a core agents TPAgent(TPA) is provided to undertake the operations of GPSO and will control the
evolution operations of each generation of population. To keep communication between different nodes at a
minimum cost, fitness evaluation tasks are implemented by the TPAgents at local nodes, only the local
minimum fitness and the corresponding best particle are sent to center node so as to get the global best

dispatched to remote node randomly. Based on the JADE, a prototype system is setup, and the simulation
results show that the proposed approach is feasible and robust. &copy; 2008 IEEE.

Abstract:In this paper, an aperiodic stochastic resonance (ASR) signal processor for communication
systems based on a bistable dynamic mechanism is proposed for detecting base-band binary pulse
amplitude modulation (PAM) signals in communication systems. All parameters in the processor can be
adjusted when needed. The adjustment mechanism is explained from the perspective of the conventional
noise-induced nonlinear signal processing. To demonstrate this processor's usability, a digital
image-watermarking algorithm in the discrete cosine transform (DCT) domain is implemented. In this
algorithm, the watermark and the DCT alternating current (ac) coefficients of the image are viewed as the
input signal and the channel noise, respectively. In conventional watermarking systems, it is difficult to
explain why the detection bit error ratio (BER) of a watermarking system suffering from certain attacks is
lower than that of the system not suffering from any attack. In the new watermarking algorithm, this
phenomenon is systematically analyzed. It is shown that the DCT ac coefficients of an image as well as the

noise imposed by the attacks can cooperate within the bistable system to improve the performance of the
watermark detection. &copy; 2008 Elsevier B.V. All rights reserved.

Abstract:The data mining technique is applied to search stable feature set and build authentication rules of
handwriting signature in this paper. Supervised by data mining technique, 10 stable features including
maximum speed, maximum acceleration, the amount and the places of inflexions and etc have been
selected from 61 original signature features. Taking the selected feature set as the input attribute, true or
false signature sample clusters are trained and learned to build authentication rules supervised by data
mining technique to test the validity of the selected feature set. The result of the test shows that the selected
feature set is effective to identify handwriting signature and the average veracity of Chinese authentication
is up to 92%. It is proved that data mining technique is an effective method to identify handwriting
signature. &copy; 2007 IEEE.

Abstract:In order to diagnose the faults of complex reciprocating machine, such as internal-combustion
engine (ICE), the vibration signals under normal and abnormal patterns were measured by experiments.
According to the nonstationarity of ICE signals, the scale-wavelet power spectrum (SWPS) of signals was
obtained by continuous wavelet transform (CWT). The wavelet power (WP) distribution on different scales
of each pattern is observed to be similar and mainly concentrated in particular scope of 1-32. By analyzing
the diversity of SWPS distribution, the WP which is most sensitive to the characteristic of each pattern
were extracted by the reduction algorithm of rough set (RS theory) as feature and taken as input to train the
back-propagation neural network (BPNN). By the trained BPNN to diagnose the fault signals under
detection, the correctness rate is 100%. The fault diagnosis method integrated on SPWS, RS and BPNN

Abstract:It is well known that high gain observers exist for single output nonlinear systems that are
uniformly observable and globally Lipschitzian. Under the same conditions, we show that these systems
admit semi-global and finite-time converging observers. This is achieved with a derivation of a new
sufficient condition for local finite-time stability, in conjunction with applications of geometric
homogeneity and Lyapunov theories. &copy; 2008 Elsevier Ltd. All rights reserved.

Abstract:The three-dimension dynamical model was established for the fixed rotating crane with
non-constant length of boom and cable. The general nonlinear differential equations of motion were
deduced by using the second kind Lagrange's equation for the system with two degrees of freedom. The
response phase orbits were discussed by using software MATLAB6.5 in particular for two instances: the
moving support radially accelerating and the boom circumrotating a fixed axis. The results show that the
former system has the angular momentum conservation and can entirely integrate, in spite of the fact that
both the total mechanical energy and the Hamiltonian function are no longer conserved. On the contrary, in
the second instances, there is no state of the angular momentum conservation, but the Hamiltonian function
is conserved.

Abstract:Based on systematic analysis of the composition and mechanism of the debris landslides, this
paper first proposes that the monthly rainfall and its change can be selected as the load-unload dynamical
parameter, the average displacement velocity and its changes as the dynamical response parameter to
load-unload and the displacement load-unload response ratio as the displacement dynamics parameter of
debris landslide induced by water in term of the principle of the load-unload response ratio theory.
Meanwhile, on the basis of analysis of the data of the displacement and rainfall of the debris landslides in
the Three Gorges Reservoirs area, the feasibility and effectiveness of the displacement dynamics parameter
are discussed. Finally, the stability of Huanglashi slope in the Three Gorges area before and after the water
drainage are evaluated respectively by means of the dynamical parameter of the load-unload response ratio;
and the evaluated results are well agreed with the practical stability situation of the slope. Therefore, all
results above show that the dynamical parameter of load-unload response ratio proposed is a very effective
displacement dynamical parameter in the stability evaluation of debris slopes; and it can be used in the
evaluation of the stability of debris landslides induced by water.

Abstract:In this paper, a novely method for speaker system is proposed. The Least Square Support Vector
Machine(LS-SVM) based on the quadratic equality constraints is analyzed firstly. A speaker recognition
system is then designed based on LS-SVM. The Mel Frequency Ceptral Coefficients (MFCCs) are adopted
as the speaker speech feature parameters in the system. The MFCC feature parameters are trained and
tested independently using the Gaussian Radius Basis Function. We evaluate the LS-SVM system using the
voice sets of similarly pronouncing speakers in the same recording conditions. The training time and equal
error rate between LS-SVM and conventional SVM in the experiments are compared. The results show that
the speaker recognition based on LS-SVM has less computational complexity, shorter training time than the
speaker recognition based on the conventional SVM. In order to test the recognition system, we use the VQ
and GMM model. The results show LS-SVM has high right recognition rate and adaptability for speaker
recognition. &copy; 2008 IEEE.

Abstract:Ant colony algorithm is a kind of bionic algorithm which sources from the behaviors of the ant
colony. Based on the idea of ant algorithm and the principle of cellular automata, this paper develops a new
mixed cellular ant algorithm and its mathematical description that can be used for solving the optimization
programs of continuous systems. By using the method, the ideal searching direction of global optimal
solution could be found as soon as possible. The algorithm is coded in MATLAB, and is tested through
series of typical optimization problem instances. The experiment indicates that the improved and mixed
cellular ant algorithm improves the efficiency of searching and veracity of result. &copy; 2008 IEEE.

Abstract:A uniaxial viscoelastoplastic model that can describe whole creep behaviors of asphalt sand at
different temperatures was presented. The model was composed of three submodels in series, which
describe elastoplastic, viscoelastic and viscoplastic characteristics respectively. The constitutive equation
was established for uniaxial loading condition, and the creep representation was also obtained. The
constitutive parameters were determined by uniaxial compression tests under controlled-stress of 0.1 MPa
with five different test temperatures of 20, 40, 45, 50 and 60 &deg;C. Expressions of the model parameters
in terms of temperatures were also given. The model gave prediction at various temperatures consistent
with the experimental results, and can reflect the total deformation characterization of asphalt sands. &copy;

Abstract:Mehrotra-type predictor-corrector algorithms are the basis of interior point methods software
packages. Salahi et al. in their recent work have shown a feasible version of a variation of Mehrotra's
second order algorithm for linear optimization may be forced to make many small steps that motivated
them to introduce certain safeguards, what allowed them to prove polynomial iteration complexity while
keeping its practice efficiency. In this paper, we extend their algorithm to monotone linear complementarity
problems. Our algorithm is different from their method in the way of updating the barrier parameter and the
complexity analysis, and we also show that the polynomial complexity of our algorithm is
O(n<sup>2</sup> log (x<sup>0</sup>)<sup>T</sup> s <sup>0</sup>/&Epsilon;). &copy; 2008

Abstract:A blind audio watermarking algorithm in the time domain is proposed. The audio signal is divided
into frames and the watermark is inserted on a frame by frame basis. The proposed algorithm detects the
watermark using a signal processor based on the stochastic resonance mechanism. The watermark detection
does not need the original audio. The parameter-induce stochastic resonance in audio watermarking is
observed and the interpretation to this phenomenon is given. For the synchronization attack, the
experimental results show that the stochastic resonance signal processor can catch up and surpass the
performance of the matched filter. This reveals a robustness superiority of the stochastic resonance signal
processor, compared to the matched filter operating outside its strict nominal conditions, which is
especially helpful for the audio watermarking. &copy; 2008 IEEE.

Abstract:Coordinated collective motion of groups of autonomous mobile robots is studied. A qualitative
analysis for the collective dynamics of multiple autonomous robots with directed interconnected topology
using nearest neighbor rules is given. A necessary and sufficient graphical condition is proposed to
guarantee that the headings of all robots converge to the same heading. The graph having a globally
reachable node plays a crucial role in convergence analysis. Furthermore, we show that the globally
reachable node having no neighbors serves as a group leader as a special case. &copy; Springer

pH value is 2, micro-local pattern and composition of sandstone under chemical corrosion were tested
using SEM and X-ray technology. In the light of analysis test and theory about chemical thermodynamics,
the corrosion mechanism was concluded for the dissolution of feldspar, calcite, and absorption of calcium.
Based on the theory of chemical kinetics, chemical thermodynamics, and solute transportation, a
reactive-transport model for describing porosity change under chemical corrosion was established. The
numerical simulation analysis was performed. The simulation result indicates that with the corrosion time
increasing, the porosity increases firstly and then goes to stabilization in the end. The results can be used as
a reference to analyze the microstructure of rock damage evolution, to set up the corresponding damage
constitutive model, and to offer an effective parameter for exactly estimating the safety and stability of
many rock engineering such as dam foundation, radioactive waste repositories, slope and tunnel which are
related to water-chemical field. &copy; 2008 Taylor &amp; Francis Group.

SSFBG is achieved. Under the impact of the interchannel interference and noise of the WDM/OCDM
system, the degradation of the pulse waveform is obvious, the width of the main peak is broadened to 8.2
ps and the sidelobe of the auto-correlation trace is increasing apparently. In the receiver, a nonlinear
amplifying loop mirror (NALM) is introduced to improve the system performance, both the sidelobe and
the pedestal are reduced, the waveform quality of decoded output signal is enhanced, and the
auto-correlation peak of decoded output pulse is compressed to 4.8 ps. The peak power of the input signal
in the NALM is about 8 mW.

Abstract:The elastic finite element analysis (FEA) and the experimental method of testing the cleavage
strength of the joint were used to investigate the effect of the recessing as well as its length on the stress
distribution in both the mid-bondline and the adherend near the interface along the bondline of adhesively
bonded steel cleavage joint. The results from the FEA simulation showed that the peak values of the
stresses distributed in the mid-bondline were nearly the same when the length of the arranged recessing was
not greater than 10 mm except that the shear stress Sxy was increased a little when the length of the
recessing was increased. For the normal stress Sy near the interface of the joint with a 16 mm length
recessing, the peak stress in the adherend is about 49% higher than the one in the adhesive at the left edge
of the joint. And it is supported with the results from the experiments that the ultimate load of the
steel-to-steel cleavage joint decreased a little when the gap length was less than 10 mm. &copy; 2008 Trans

Abstract:A method of reliability evaluation for complex medium-voltage distribution system based on
simplified network model and network-equivalent is proposed in this paper. According to the topology of
distribution system and the function of the protection device and the switch, a distribution network is
divided into different zones, the distribution network based on electrical components is changed into a
simplified network based on zones. This simplified network is laminated, based on network-reliability
equivalent, thus a simple radial network is equivalent to original simplified network by use of the
consequence analysis of fault Pattern of the reliability index of the complex distribution system can be
calculated. To implement the proposed method, a distribution network is regarded as a directed graph and
the topology of the network is realized by adjacent matrix of the graph, through the search and modification
of adjacent matrix can realized the partition of the distribution network and network-equivalent, so the
topology of the network can be immediately modified while the reliability index can be calculated. The
application of the proposed algorithm to RBTS-Bus6 shows its effectiveness.

Abstract:In view of the inadequacy and limitation in application of the strength reduction FEM in the slope
safety factor analysis, it is proposed to use the gravity reduction FEM based on changing the gravitational
acceleration, and pointed out that the overload reserve safety factor is not equal to the strength reserve
safety factor that only reduces the cohesion. The analytical results indicated that the two methods could be
used interchangeably in a certain extent when the slope angle is over 60&deg;. When the slope angle is less
than 45&deg; and calculation depth is large, the two methods are not suitable for single-layered high slopes.
For double-layered lopes, the slope safety factor calculated using the gravity reduction FEM increased
much more rapidly than that using the strength reduction FEM along with increasing slope angle. For
three-layered slopes, the conclusion from the gravity reduction FEM analysis was more suitable than the
strength reduction FEM. In addition, the gravity reduction FEM greatly simplifies the computing process
due to its merit in needing not to assume the sliding surface as in the strength reduction FEM, with the
computing time being only 3/10-1/7 of the strength reduction FEM, and the computing efficiency rises with
increasing number of rock layers.

by capillary electrophoresis from the same plant. The absolute configurations at C-2 of 1a and 1b were
determined based on their circular dichroism spectra. Enzymatic hydrolysis of 1a and 1b by
&beta;-d-glucosidase afforded (2R)- and (2S)-eriodictyol, respectively, which were used as the authentic

Abstract:In this paper, a new approach is presented for finite-time control problems for linear systems
subject to time-varying parametric uncertainties and exogenous disturbance. The disturbance is assumed to
be time varying and bounded. Sufficient conditions are obtained for the existence of a linear
parameter-dependent state feedback gain, which can ensure that the closed-loop system is finite-time
bounded (FTB). The conditions can be reduced to feasibility problems involving LMIs. Numerical
examples show the validity of the proposed methodology. &copy; 2008 Editorial Board of Control Theory

Abstract:Nano hydroxyspatite (HA) is a potential artificial cartilage material. To study its friction and wear
properties, nano hydroxyapatite (HA) particles filled with polyvinyl alcohol hydrogel (PVA-H) composites
were slid against a stainless steel disk underwater lubrication condition using an Improved four-ball tester.
The worn surfaces were investigated by using a scanning electron microscope (SEM) to determine the wear
mechanisms of pure PVA-H and PVA-H/HA composites prepared by different methods. Experimental
results show that the addition of HA slightly decreases the friction coefficient of composites with the
increase of HA content under water lubrication condition. The wear resistance of the PVA-H matrix was
also improved by the introduction of HA inorganic component. It was also found that the PVA-H/HA
composites prepared by in situ synthesis have better tribological properties than the composites prepared by
mixed method with the same components and test conditions. The SEM photos show that the wear
mechanisms of PVA-H/HA composite prepared by the mixed method with high HA content showed
abrasion and adhesion, while that of the composite prepared by in situ synthesis was slightly scratched and
fatigued. These results may be useful in the tribological designs for artificial articular cartilage material.

Abstract:The seismic stability analysis of rock-soil slopes based on finite element method (FEM) are given
in this paper. A new average seismic coefficient method is proposed, where the seismic coefficient of the
potential sliding block is determined using the FEM, and then the safety factor is calculated according to
the pseudo-static method. In order to consider the influence of slip deformation on seismic stability and
permanent deformation, the coupled computational method of seismic response and permanent deformation
should be established. It is a scientific and rational method where permanent displacement or accumulated
deformation is used as slope stability evaluation index. Finally, the performance-based seismic design
method is proposed, including the classification of performance level of slopes, the definition of
performance index and the seismic design method.

Abstract:The experiments of soil-water characteristics curves are made under different consolidation
pressures for sliding zone soils of Gushubao landslide in the Qingjiang valley, with an advanced
unsaturated soil shear instruments which can control suction. The experiments show clearly the influences
of consolidation pressure on the soil-water characteristics curves. The varied consistent functions have been
established from the experiment data of soil-water characteristics curves; and the physical meanings of
parameters in the consistent functions have been deduced and discussed. Finally, a comprehensive function
expression which can reflect the relation among consolidation pressure, suction and water content, is
established. The study has made up for the deficiency of other methods which can not consider the
consolidated pressure and is very significant for the supplement and development of the theory and
experimental method of soil-water characteristics curves.

Abstract:Effects of direct current (dc) bias-drifting on the carrier suppressed double sideband (CS-DSB)
and single sideband (SSB) radio on fiber (RoF) link are theoretical investigated. Power variation of targeted
harmonic signal and harmonic suppression are calculated and evaluated. The theoretical results show that
the degradation of harmonic suppression is evident and power variation is negligible in CS-DSB RoF link
while power variation is visible and harmonic suppression is stable in SSB RoF link on account for
bias-drifting. The obtained results can provide important assistance for qualitative and quantitative analysis
for fiber-optic microwave and millimeter-wave link application and system design.

Abstract:The effect of corrosion on the bond between concrete and plain bar reinforcement without stirrups
is studied during cover cracking and before cover cracking. A new analytical model of splitting stresses is
formulated based on mechanics of elasticity. Then the critical attack penetration depth of reinforcing bar at
the time of cover cracking was calculated. Based on the existing research fruits, an explicit function
expression for the friction factor between steel bar and concrete was provided. With the effects of
deterioration of bar surface and increase of splitting stresses on bond strength taken into consideration, a
model was proposed to calculate the bond strength during cover cracking and before cover cracking. The
theoretical results were compared with experimental results, showing good agreement. The mechanism of
increase in bond strength was analyzed quantitatively from the increase of both friction factor and splitting
stresses.

Abstract:This Letter deals with the global exponential synchronization of a class of chaotic networks with
time delays. Based on the Halanay inequality technique and the Lyapunov stability theorem, the global
synchronization of a network about its all variables is derived by only considering the global
synchronization of its partial variables, and a delay-independent criteria and decentralized control law is
derived to ensure the adaptive exponential synchronization of the model and these results are proved to be
able to guarantee different exponential convergence rates for the controlled states and the uncontrolled
states of the error systems, respectively, and the simpler, less conservative and more efficient results are
easy to be verified in engineering applications. Finally, an illustrative example is presented to verify the
effectiveness of the presented synchronization scheme. &copy; 2008 IEEE.

Abstract:Mehrotra-type predictor-corrector algorithms are the backbone of most Interior Point Methods
based software packages. Recently Salahi et al. have considered a variant of Mehrotra' s celebrated
predictor-corrector algorithm for linear optimization problem. By a numerical example they showed that
this variant might make very small steps in order to keep the iterate in a certain neighborhood of the central
path, which implies the inefficiency of the algorithm. This observation motivated them to incorporate a
safeguard in their algorithmic scheme that gives a lower bound for the step size at each iteration and thus
imply polynomial iteration complexity. This paper extends their approach to the monotonic linear
complementarity problem. As the search directions &Delta;x and &Delta;s aren't orthogonal any more, the
complexity analysis of this method is different from that of linear programming, correspondingly. We
proved that the extended algorithm, in the worst case, will terminate after at most O (n<sup>2</sup>
log(x<sup>0</sup>)<sup>T</sup>s <sup>0</sup>/&Epsilon;) iterations and the computational result
indicate that our algorithm is efficient. &copy; 2008 IEEE.

Abstract:The genetic particle swarm optimization (GPSO) was derived from the original particle swarm
optimization (OPSO), which was incorporated with the genetic reproduction mechanisms, namely
crossover and mutation. To combine the characteristics of GPSO and OPSO to solve constrained
optimization problems, the paper presents a dual particle swarm optimizations (Dual-PSO), where OPSO
and GPSO were incorporated, which are continuous and discrete editions PSO, respectively. To deal with
the constraints, the stochastic ranking algorithm was employed. Based on which Dual-PSO was introduced,
where at each generation GPSO and OPSO generated a new position for the particle synchronously and
respectively, with the original position of the particle, and the better one was accepted as the new position.
Dual-PSO was experimented with well-known benchmark problems with various stochastic ranking
parameters, and by comparison with the evolution strategy, the results have shown robust and consistent
effectiveness of Dual-PSO. &copy; 2008 IEEE.

Abstract:This paper studies the packing optimization about how to place the circular and weighted objects
in a circular container, while the system should be in good balance and the container should be as small as
possible. The problem-solving strategy can be applied to place some devices or instruments in the satellite.
We first provide an orderly positioning technique , which placing the circles one by one in a given order
and can give out a compact layout. Because different packing orders can lead to layouts in different quality,
we then develop a particle swarm optimization (PSO) algorithm to search for the optimal order and then the
optimal layout. At last, some numerical experiments are carried and the PSO algorithm is compared with a
existing novel genetic algorithm. The results show that the PSO algorithm can compete with the genetic
algorithm. &copy; 2008 IEEE.

Abstract:A new Lyapunov function was constructed without the term of disturbances, and some sufficient
conditions were given for finite-time boundedness for a class of discrete-time systems with exogenous
disturbances. The disturbances were generated by an exosystem. Compared with the existed results, these
conditions can decrease the conservation. Some sufficient conditions for the existence of state feedback
controller and output feedback controller were also given. These conditions can be reduced to feasibility
problems involving linear matrix inequalitie (LMI). Finally, the proposed methodology was illustrated by
an example.

coefficients of dry soil grain are analyzed for different composition geomaterials; and the thermodynamical
properties of porous media with water and gas are researched; the comparative analyses of different
calculation methods of thermal conductive coefficient have been conducted; an available calculating

Abstract:A particle flow model of ring-shear test is constructed by the PFC (particle flow code) in which
the soil particles are cohesiveless. Compared the result of simulation test with high-speed ring-shear test,
the stress changing tendency of the two tests is similar; the levels of stress are close. The uniformity
coefficient of the sand sample in ring-shear test is 1.64 and the particle sample in PFC model is 1.45. The
linear contact model among balls is adopted in the simulation test, so the test result is suitable for the
cohesiveless soil. The shear boundary can make different kinds of shear zones, so three kinds of boundaries
are tested, which are wall, ball-circle and ball- circle and teeth boundary. And the ball-circle and teeth
boundary is the one that can make shear zone well proportioned.

Abstract:The numerical analysis was carried out to study the influence of the water absorption on the stress
distribution in the polyacrylate adhesive layer of the single lap joint using the elasto-plastic finite element
analysis (FEA) based on absorption constitutive model of the adhesive established by the authors. The
results from the numerical simulation show that the peak stress at the comer of the fillet decreased
evidently as the moisture absorption level increased. The stress distribution was also studied and it is found
mat the peak equivalent stress in the adhesive layer decreased greatly as the sum absorption width
increased and the maximum equivalent plastic strain was gradually increased and maintained its location at
me corner of the fillets when took the sum width of the adhesive as 2 mm, 4 mm, 8 mm and 10 mm
respectively. The swelling of the adhesive should be occurred after the moisture absorbed into the adhesive
layer and the severe deformation of the adhesive taken place so that the de-bond of the adhesive layer at the
interface maybe occurred.

Abstract:Excitation Control System (ECS) of the generator is a key control unit that can adjust the reactive
power and bus voltage for power network. If the faults in ECS could not be detected, the security, quality
and economy of the power system will be affected. Therefore, fast and precise fault diagnosis for ECS is
very important. This thesis makes a conclusion that artificial neural networks (ANN) possess special
advantages for the excitation control system fault diagnosis (ECSFD) and has et up a new four-layer
(including the input layer) model for ECSFD. The key of ECSFD is learning of ANN, and the learning of
ANN is depended on the correct input/output (I/O) patterns. For this reason, this paper collects a number of
real fault patterns and plentiful expert knowledge patterns. Through analyzing the model effect causing
from different ANN parameters, this paper discovered one group of parameters that can diagnose the fault
from the Generator Excitation Control System exactly and speedily. Since the research can be applied to
practice directly, this paper will show the important and useful value in the application.

Abstract:This paper illustrated a novel registration method for planar scene based on natural features
tracking via affine transform. Our method can be divided into two stages: offline 3D reconstruction and
online registration. With the obtained feature correspondences, the homographic was computed between the
world plane and the current frame robustly. Then, the registration matrix was synthesized based on the
above homographic and the transform matrix between the plane and world coordinate system obtained in
offline stage. The proposed method also distinguishes itself in two ways: Firstly, a new method was
established in the world coordinate system. Secondly, a novel affine transform based method to match
features between reference images and currently frame directly. The method can avoid the user's
intervention in initializing stage, while overcoming the problem of error accumulation. Some experiments
were carried out to demonstrate the validity of the proposed approach. &copy; 2008 IEEE.

Abstract:Some properties of phosphorus-slag concrete, such as the strength, elastic modulus, ultimate
tension, shrinkage, self-volume deformation and adiabatic temperature rise are studied in this paper. The
results show that when phosphorus-slag is added into concrete, the strength of hydraulic concrete is not
affected, but the ultimate tension, the adiabatic temperature and the shrinkage are all increased. Beside, the
elastic modulus and self-volume deformation are reduced when phosphorus-slag and fly ash are added
compositely into concrete. The hydration mechanism of phosphorus-slag is also studied in this paper. On
the whole the phosphorus-slag can improve some properties of hydraulic concrete and be advantage for
dam safety.

Abstract:The development and application of single-photon detectors are introduced. The operating
principles of photomultiplier tube (PMT), avalanche photodiode (APD) and superconducting, single-photon
detector (SSPD) are expounded. The characteristic, advantages and disadvantages of them are discussed.
Then give a view for the perspective and the development of these devices. In the above types of
single-photon detectors, the PMT can't detect photon in near-infrared while the APD has great advantage on
it, so it is the most preponderant detector in the single-photon detection. The capability of SSPD are
excelled the former single-photon detectors, besides, it can detect the arriving time and energy of the
photon, so it has great potential in the astronomical observation and the high-speed quantum
communication and so on.

Abstract:In this study, a novel procedure is presented for control and analysis of multiple autonomous
agents with point mass dynamics achieving flocking motion with a time variant leader. Two control laws
are proposed for a group of autonomous agents to achieve flocking formations related to two different
centers (mass center and geometric center) of the flock. The first one is designed for flocking motion based
on mass center and the second for geometric center. Distance-dependent adjacency matrix is used to
quantify the way agents influence each other. Theoretical analysis is established to indicate the stability
(cohesiveness, collision avoidance and velocity matching) of the control systems using classical Lyapunov
theory. Finally, a simulation example is demonstrated to validate the theoretical results. &copy; 2008

Abstract:Statistical theory is used to help select a margin level. This paper present a prudent margin-setting
models to protect futures positions from extreme price movement. Five methods based GARCH models to
estimate the current volatility are proposed to estimate Value at Risk describing the tail of the conditional or
unconditional distributions of two financial return series. Using backtesting of historical daily return series
we show that our procedure gives better 1-day estimates than methods which ignore the heavy tails of the
innovations or the stochastic nature of the volatility. Furthermore, the empirical results show that the
default risk of GPD distribution is judged to the most prudential method among the three fat fail
distributions. &copy; 2008 IEEE.

Abstract:Rockburst is a kind of dynamic instability phenomenon of surrounding rock in underground
projects in deep high-geostress zone. The prediction of possibility and classification of rockburst are basic
issues in many underground projects. Based on the fuzzy probability theory, a new fuzzy probability model
is established to predict rockburst occurrence and its intensity. Some main control factors of rockburst, such
as the maximum tangential stress of the cavern wall &sigma;<inf>&theta;</inf>, the uniaxial compressive
strength &sigma;<inf>c</inf>and the uniaxial tensile strength &sigma;<inf>t</inf> of rock, the elastic
energy index W<inf>et</inf> of rock, are chosen in the analysis. Three factors including
&sigma;<inf>&theta;</inf>/&sigma;<inf>c</inf>,
&sigma;<inf>c</inf>/&sigma;<inf>t</inf>
and
W<inf>et</inf> are regarded as the evaluating indices. And rockburst intensity is classified as the
non-rockburst, slight rockburst, medium rockburst and serious rockburst in the prediction model. In order
to assess the index weight scientifically and to avoid the uncertainties while determining the index weight,
the fuzzy weight is introduced into the rockburst prediction model. The fuzzy probability model not only
holds the merits of classical fuzzy comprehensive evaluation method, but also overcomes its limitations in
practice. Rockburst predictions of Dongguashan deep hard rock mine, Qinling Tunnel and an underground
hydropower station are performed by this model. Furthermore, 23 underground rock projects at home and
abroad are also evaluated with the proposed method. The prediction results agree well with the practical

classification of rockburst in deep underground engineering.

Abstract:How to decide the parameters of bolted rock mass is an important and complicated problem in
geotechnical engineering. Taking unloading into account, the variation regularity of compression strength,
Poisson's ratio, elastic modulus, c and friction angle values were studied and simulated by computer; and
different loading-unloading paths, anchoring angle, strength of rock mass were taken into account. The
computed results show that the influence of unloading process before reinforcement should not be
neglected. Finally, some experimental data were used to testify the above-mentioned analysis.

Abstract:According to the fuzzy probability theory in fuzzy mathematics, a comprehensive fuzzy
probability evaluation model of sand soil liquefaction is presented. In order to consider the fuzziness of
weight factor, the fuzzy weighted value is suggested to avoid the uncertainties while determining the
weight factor. The following factors such as earthquake intensity, standard penetration number, mean
diameter and effective over burden pressure are selected as the evaluating indices; and liquefaction grades
are classified as the non-liquefaction, slight liquefaction, medium liquefaction and serious liquefaction in
the evaluating model; so the evaluation results can be more precise. The theoretical model is successful
applied to evaluating liquefaction of sand soils in practical engineering; and the rationality and
effectiveness of the method proposed is demonstrated through 22 examples.

Abstract:On the basis of the systematic analysis of the dynamic displacement factors and destabilized
mechanism of debris landslide induced by water, the dynamic action and its response law of groundwater in
the process of the dynamic stability evolution of the slope are systematically analyzed. It is discovered that
the displacement and destabilization of the debris landslides induced by water are directly controlled by the

variation of groundwater quantity; and its displacement law has corresponding relation with the change
quantity of groundwater. According to the above analytical results and the principle of the load-unload
response ratio theory, the theories that the monthly change of groundwater table can be taken as the
load-unloaded parameter of debris landslide and its displacement velocity and acceleration rate can be
taken as the response parameter to load-unload are proposed. Thus, the dynamic displacement parameters
and dynamic prediction model of the load-unload response ratio of the groundwater table are determined.
Meanwhile, taking the typical debris landslide of the Three Gorges Reservoir region-Bazimen landslide for
example, the load-unload response ratio of the key monitoring points SZK1 and SZK4 of Bazimen
landslide are calculated by means of the load-unload response ratio model of the groundwater table. The
computation results show that the curves of load-unload response ratio of monitoring points SZK1 and
SZK4 agree with the dynamic evolution law of the slope stability. All the above-mentioned results show
that the groundwater table dynamic model of the load-unload response ratio can be used to perform the
complete dynamic prediction of the debris landslides.

Abstract:The contact relations between rockfill and concrete can be simulated truly by Clough hyperbola
constitutive model, and the contact state can also be simulated by augmented Lagrangian multiplier
algorithm accurately. Clough hyperbola constitutive model has been applied on jointed element with no
thickness and Desai interface element with thickness successfully. Those merits and success experiences
are absorbed and combined to be applied on solution of contact friction problem. Sequential quadratic
programming method (SQP) is introduced based on augmented Lagrangian multiplier contact algorithm in
the same time. Numerical algorithm and implementing steps that Clough hyperbola constitutive model is
inducted into augmented Lagrangian multiplier contact algorithm are derived in detail. The computation

Abstract:The nonlinear optical loop mirror (NOLM) and the nonlinear amplifying loop mirror (NALM)
based optical thresholding in the high speed OCDM system are analyzed, the input pulse peak power of the
NOLM is optimized considering the thresholding decision function, pulse shaping and side-lobe
suppressing of the NOLM based on high nonlinear fiber (HNLF) are numerically simulated, and theoretical
investigation is compared with experimental result. The results show that the interference noise in the 40
Gbit/s OCDM system could be suppressed effectively by the optical thresholding techniques based on the
NOLM and the NALM. We show that the NOLM and the NALM can act as a nonlinear processing element
capable of reducing both the pedestal associated with conventional matched filtering and the width of the
associated code recognition pulse. &copy; 2008 SPIE.

Abstract:In this paper, the problem of robust adaptive convergence for uncertain Cohen-Gross berg neural
networks(CGNNs) with mixed delays is investigated. Using the Lyapunov method and employing a novel
lemma, some delay-independent conditions are derived to ensure the state variables of the discussed robust
system to converge, globally, uniforymly, exponentially to a ball in the state space with a pre-specifled
convergence rate. The effectiveness and usefulness of the results has been verified by a numerical example
with graphical illustrations. &copy; 2008 IEEE.

Abstract:An algorithm for computing 4<inf>M</inf> -point DFT based on 4-point DFT block is developed.
The new algorithm, in comparison to radix-4 FFT algorithm, requires the same number of additions and
multiplications, but employs a dissimilar flow-graph. In the flow-graph of the new algorithm, the 4-point
DFT blocks replace the accustomed butterfly computational networks. The new algorithm permits one
4<inf>M</inf>-point DFT to be computed using a 4-point DFT block, and the block requirements is
M&times;4<inf>M-1</inf>. Because the total number of computational requirements of directly computing
a 4-point DFT is only 16 real additions, a command block and hardware block for computing 4-point DFT
may be obtained. When using a processor which integrates with a fast 4-point DFT block to compute
4<inf>M</inf>-point DFT, the speed of DFT will be faster than that of radix-4 FFT. The algorithm based
on 4-point DFT block will be helpful to improve the DSP technology and speed. &copy; 2008 IEEE.

Abstract:A physical model is proposed to study the laser-induced plasma dynamics expansion during
irradiation of material by a high-intensity nanosecond pulsed laser beam. Based on a consideration of the
plasma ionization effect and local conservations of mass, momentum and energy, combined with the
assumption that plasma can be viewed as a compressible ideal fluid and a high temperature-high pressure
ideal gas, we developed a new dynamics expansion mechanism for plasma produced by pulsed laser
radiation. A set of new plasma expansion dynamics equations based on our model are first deduced. Then,
taking the example of the carbon target, using the finite difference method, the plasma flow dynamics into a
vacuum, such as plasma spacial number density distribution, plasma number density and velocity
evolvement in radial and axial directions, are studied in detail. The results show that there are some main
factors affecting the velocity distribution of the plasma, including the temperature of the plasma, the
ionization fraction of the plasma and the dynamic source provided by the vaporized material. The velocity
u<inf>z</inf> in the longitudinal direction is different from u<inf>r</inf> in the transverse direction
because of huge initial eject velocity and evaporated dynamic source. The velocities of the plasma
calculated by this model are found to be in better agreement with the experimental results derived from the
work of Sanz et al (1985 Plasma Phys. Control. Fusion 27 329) compared with the conventional model.

Abstract:An automatic relative radiometric normalization algorithm of multi-temporal remote sensing
images based on pseudo-invariant neighborhood was introduced in this paper. The main purpose of this
research was to develop a robust algorithm of relative radiometric normalization to minimize imaging
differences of multi-temporal satellite images. The main idea was to construct statistical regression model
of relative radiometric normalization by pseudo-invariant neighborhoods, which were obtained by
extracting steady ground point correspondences. The algorithm's detailed processes were as follows: First, a
method of image matching was applied to recognize ground point correspondences of multi-temporal
remote sensing images. Second, steady ground point correspondences were determined by matching results.
Third, sample dataset of steady ground point correspondences was obtained by pseudo-invariant
neighborhoods. Finally, a statistical regression model of relative radiometric normalization was constructed
to calibrate imaging differences of multi-temporal remote sensing images. By the experiments, we could
see that the total RSME of reference image and calibrated image was reduced apparently in comparison
with the total RSME of reference image and un-calibrated image. We could conclude that this modified
algorithm was more accurate and efficient than traditional algorithm, and the result of calibration was more
objective and dependable. &copy; 2008 IEEE.

Abstract:Ferroelectric Bi<inf>3.25</inf>La<inf>0.75</inf>Ti<inf>3</inf>O <inf>12</inf> (BLT) and
Bi<inf>3.15</inf>Nd<inf>0.85</inf>Ti<inf>3</inf>O <inf>12</inf> (BNT) thin films were fabricated on
Pt/TiO<inf>2</inf>/SiO <inf>2</inf>/Si (100) substrates by a modified sol-gel technique. X-ray
diffraction indicated that these films were of single phase with random polycrystalline orientations. The
surface morphologies of the films were observed by scanning electron microscope, showing uniform, dense
films with grain size of 50-100 nm. Well-saturated hysteresis loops of the films were obtained in
metal-ferroelectric-metal type capacitors with Cu top electrodes at an applied voltage of 400 kV/cm, giving
the remanent polarization (2P <inf>r</inf>) and coercive field (2E <inf>c</inf>) values of the films of 25.1
&mu;C/cm<sup>2</sup> and 203 kV/cm for BLT, and 44.2 &mu;C/cm<sup>2</sup> and 296 kV/cm for
BNT, respectively. Moreover, these capacitors did not show fatigue behaviors after up to
1.75&times;10<sup>10</sup> switching cycles at the test frequency of 1 MHz, suggesting a fatigue-free
character. The influences of the La<sup>3+</sup> and Nd<sup>3+</sup> doping on the properties of the
films were comparatively discussed. &copy; 2008 Science in China Press and Springer-Verlag GmbH.
