Automating and Improving Regression Testing
The requirement changes of software project can be accommodated
because software is flexible. Even though the change may take
considerable efforts, this is one of the attractive software
characteristics and one of the key reasons that software becomes
increasingly important for modern society. Because a software
system may be frequently modified in the development process, it is
critical to control the quality of the software components that were
not modified. Regression testing runs the test cases that have been
Specification
executed before each software modification and intends to ensure
that the quality of the software system is the same as that of the
original one. Please notice that it will take considerable costs to
manually run all test cases. Thus, our research is focused on
automating the regression testing in order to reduce the cost of
regression testing. Additionally, we also aim to improve the
effectiveness and efficiency of regression testing via two helpful
techniques, test suite reduction and test case prioritization.

Chinese Document Classification
Document classification is a natural language processing technique,
which assigns a document to a class according to its content.
Machine learning method is often used in practice to implement the
technique. Learning algorithm analyzes training data to generate the
classification model, which is used to determine the class of the input
document. In order to classify Chinese document, we develop
Specification techniques such as Chinese pre-processing, feature generation,
feature selection, and generating classification model using SVM.
These techniques can be used to process a large number of Chinese
documents and determine their classes. There are many application
areas: spam filtering, assessing document readability for elementary
school students, determining whether a product review is positive or
negative, finding documents that have similar main topics, etc.

3D graphics technologies have grown rapidly over the past ten years
due to the fact that both computer games and 3D animations require
diverse motions of humanlike characters to pour the contents. We
propose two 3D animating methods, including kinematic and dynamic
techniques, towards both bipedal and quadrupedal characters for
motion simulations. Kinematics-based approach is an intuitive and
easy-to-implement method that has less computational complexity
than the dynamic approach, but users need to formulate animation
Specification
rules and to deploy the parameters of character bodies, such as step
height or rotation of bones. On the other hand, the dynamic approach
must follow the laws of physics to determine the joint forces and
torque so that it is capable of simulating more plausible motion effects
than applying the kinematic approach. We experiment the proposed
techniques on articulated characters and we also give the simulation
results to demonstrate that the techniques can be used in a wide
variety of ways, including locomotion and reaction simulations.

Spelling Error Detection based on Language Models and Web
Resource for printing
People often find out spelling errors after printing the documents,
therefore they need to re-print the contents of the documents.
However, it is a waste of paper, ink, printer, power, other resources
and so on. Even more they would need to spend extra time without
efficient. This paper addresses reducing spelling errors before
printing. The language model used in this research to compare and
increase a new feature additionally that is a function of Internet
search. Combining these research manners, this paper expect to
achieve the goals of confirming, improving the spelling error, and
reducing the waste of resources. This investment proposed a spelling
Specification check method that combined language model and knowledge
resource. Since typos and error hidden in printed document is
frequent, rework will cause the waste of paper and ink. Even more
they would need to spend extra time without efficient. This paper
addresses reducing spelling errors before printing by the proposed
spelling check method. In this method, the language model used in
this research to compare and increase a new feature additionally that
is a function of Internet search. Combining these research manners,
this paper expect to achieve the goals of confirming, improving the
spelling error, and reducing the waste of resources. Experimental
results shows, the proposed method is practicable and efficient.

Encrypting high dynamic range images
Multimedia information, especially images, has been consumed in
people’s daily life. With therapid development and convenience of
networks, we are surfing, obtaining and transferring varied
multimedia via the Internet. Consequently, there are security issues
worthy to concern about such as confidentiality, authentication, etc.
Due to the restriction of consumer electronics, the monitor or
projector can only display images of low-dynamic range (LDR). LDR
images are represented with size of 8, 10 and even 12 bits for each
color channel of RGB format. It is difficult to cover the gamut of
human’s vision because the human visual system can distinguish
more colors in the real world than the display of LDR images.
Fortunately, high-dynamic range (HDR) imaging formats have
al-ready been developed. The HDR format is more accurate than
Specification LDR to display such that the darkest area as shadow and brightest
area as sunlight in HDR images are possible. In HDR imaging, the
raw format is 32-bits for each color channel R, G, B and totally
96-bits. The size of raw HDR format is comparatively huge, therefore
we are used to adopt other fewer bits HDR format such as LogLuv,
RGBE, or OpenEXR instead.
While HDR imaging has become a new trend in academia and
industry, it comes with the issues of security including confidentiality.
In recent years, there is more and more attention drawn for image
encryption. However, these schemes for encryption are suitable only
for LDR images, not applied on HDR images directly. In our research
interest, the HDR tailor-made encryption scheme is proposed to
encode LogLuv/RGBE/OpenEXR images for guaranteeing
confidentiality while format-compliance is achieved.

The Technology of Clouding and APP
Most Management Information Systems need the computer
applications to improve the working efficiency. The development
trend of mobile devices advances the massive need for the APPs of
the mobile devices. We have the capability of APP development for
the newest version of Google Android system. We can also develop
the APPs in Apple’s iOS system and Microsoft System. Since the
Specification limitation of the mobile device, a large number of data of
Management Information System always has been designed in the
Internet Cloud. We provide the Cloudy technology to reengineer the
Management Information System. We can also redesign the Cloudy
applications to be suitable the mobile device by the new design style,
such as Web 3.0, Representational State Transfer (RESTful), Push
Technology, Responsive Web Design (RWD), and etc.
