Abstract— One of the key drivers in the uptake of LTE as a new technology is to get the most out of the
network, meet subscriber demands and develop new revenue growth plans, this makes radio network planning
an essential process for operators looking to make the most of their networks. In order to achieve the radio
network planning, there are a number of stages that are typically performed, these includes: Initial planning,
detailed planning and optimization. The initial phase of network planning is known as dimensioning. The
purpose of dimensioning is to estimate the required number of radio base stations needed to support a specified
traffic load in an area. Dimensioning has two phases: coverage planning phase and capacity planning phase.
This paper focuses on the coverage planning phase; a GUI tool was designed and simulated using MATLAB
program that provides the number of sites required in coverage planning phase.

Abstract: This paper introduces the concept of visible light communication (VLC). Visible-light
communications (VLC) is a technology for wireless communication using light that can be perceived by the
naked eye. VLC uses frequencies other than radio, and they are unrestricted and licence free. The urgent need
of VLC is to overcome the problems faced in RF communication. Unlike existing methods of wireless
communication, the visible light portion of the electromagnetic frequency spectrum is used in VLC to
transmit information. Visible light communication (VLC) refers to the communication technology which
utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate
photodiode as a signal receiving component. This paper provides an overview of applications and design
challenges for VLC, compare it with other existing communication technologies and presents the modulation
techniques used

4. A Combined Open-Closed Loop Power Control for LTE Uplink
International Journal of Scientific & Engineering Research, Volume 5, Issue 1,pp 234-237 January-2014

Abstract— Long Term Evolution (LTE) is a new standard of the 3GPP, designed to increase capacity and
improve service performance. Single Carrier FDMA is the multiple access technique used in the uplink, it
avoids the intra cell interference typical of CDMA systems, but it is sensitive to inter-cell interference. This
makes the power control functionality a vital issue. Power control needs to reduce inter-cell interference level
and at the same time achieve a required SINR level. This paper proposes a combined open-closed loop
algorithm component that enhances the uplink power control and set the power smartly for the user. The
combined algorithm uses the fractional power control algorithm in the open loop and the conventional closed
loop algorithm in the closed loop. In this paper the uplink power control schemes were analyzed and the
results showed that the combined algorithm outperformed both the open and the closed loop algorithm since
it features a cell autonomous mechanism that controls the interference and sets the UEs to transmit with a psd
according to the gain in the throughput it would generate. Also, it introduces the possibility of setting the
transmission power of the users to provide a minimum SINR.

Abstract: Centrifuge is a device used to separate materials from each other based on certain percentages. A
nuclear centrifuge is a device that performs isotope separation of gases. It is used to separate uranium-235
from uranium-238. To perform the separation process, uranium hexafluoride gas is placed in a hollow
cylinder and rotated at a high speed. This rotation creates a strong centrifugal force so that the heavier gas, U238 is thrown towards the edge. The lighter U-235 moves up where it is collected. In this paper a prototype
that simulates a nuclear centrifuge was designed using DC motors that operate at different speeds to perform
the separation process. The centrifuge was wirelessly controlled allowing people working in that area to
control it from a distance without being exposed to radiation and toxic chemicals

Abstract— providing an automatic handover for any moving device in a heterogeneous network with
different access technologies is the main aim of Next Generation Networks. Using the global mobility
protocol for managing localized mobility causes a number of problems, such as long registration delay,
signalling overhead and location privacy. To overcome these problems, Proxy Mobile IPv6 is proposed which
can avoid tunnelling overhead over the air and provide support for hosts without an involvement in the
mobility management. In this paper, we present a UMTS-HSDPA and Mobile WiMAX interworking
architecture based on the 3GPP and WiMAX standards and explain the seamless inter-system handover
scheme using PMIPv6 which enables the service continuity with low handover latency.

Abstract— Call admission control (CAC) is one of the basic mechanisms for ensuring high quality of service
(QoS) offered to the user in Wireless Networks. Based on the available network resources, it estimates the
impact of accepting or blocking a new session request. Many CAC algorithms have been proposed in the
literature but they were all limited by the available bandwidth. This paper proposes a bandwidth adaptation
technique for the Adaptive Joint CAC (AJCAC) algorithm; it is proposed as a solution for congestion; where
the AJCAC algorithm degrades the bandwidth of some ongoing users to make room for new incoming ones.
A restoration process must take place when the network is underutilized; where the algorithm restores the
maximum bandwidth service to the degraded users. In this paper the bandwidth degradation process was
investigated and evaluated. The results showed that as the degradation in the bandwidth increases, the
adaption required in the network also increases. On the other hand, degradation in the QoS results in
decreasing the blocking probability

Abstract— Heart diseases are among the main causes of death in the world. Therefore, it is necessary to have
proper methods to determine the cardiac condition of the patient. ECG signals of the heart being a self-similar
object; can well be considered for fractal analysis. Fractal Dimension method was used to distinguish and
analyze three specific heart diseases namely Premature Atrial Contraction (PAC), Premature Ventricular
Contraction (PVC), and Atrial Fibrillation from the normal ECG signal. Rescaled range method was used to
determine the specific range of fractal dimension for each disease. A Graphical User Interface (GUI) was
designed using MATLAB program to calculate the Fractal Dimension, to distinguish between the ECG
signals of healthy person and patients with the three specific heart diseases from the raw ECG data. ECG
signals used were taken from three databases, the MIT-BIH Arrhythmia Database, the MIT-BIH Normal
Sinus Rhythm Database, and the Intracardiac Atrial Fibrillation Database. The results show that the
methodological analysis does provide a significant clinical advantage, and matches the doctor’s opinion.

Abstract:Mobile communication companies at present are looking for a 4G technology that aims at better
reliability. This aim can be achieved by using Multiple Inputs Multiple Outputs (MIMO) system which is
difficult to implement for the mobile terminals due to the limitations of the complexity, size and cost. So,
these companies have been looking for a system which emulates a MIMO system. The cooperative relaying
system has been proposed as a solution to be used to take the advantages of MIMO. The cooperative relaying
system enables single antenna mobiles in a multi user environment to share their antennas and generate a
virtual multiple antenna transmitters. In this paper, we investigate a single relay system that aims for a reliable
communication. The main goal of this paper is to study the feasibility of the proposed single relay cooperative
transmission in the mobile environment, and evaluate it with respect to the direct link transmission. Both
systems are presented and a comparison in terms of bit error rate (BER) reveals that the single relay system
performs better. The proposed single relay system needs an efficient coding technique to improve the
performance in terms of reliability. Therefore, STBC as a coding technique is used, and the results proved that
this technique decreases the BER.

Abstract – Multimodal biometric solutions can provide increased reliability and robustness in many
applications where identity verification is important, and especially so in highly interactive scenarios such as
those represented by internet based transactions. Yet multimodal configurations increase complexity and
raise questions about the need for effective system optimisation. This paper describes an approach that uses
genetic algorithms to evolve efficient configurations in such applications, and shows how such structures can
be embedded within a broader implementation framework, which is especially suited to supporting typical
transactions
