Web databases are convenient methods of sharing and retrieving data as well as a key component of the information system infrastructure of today's modern research, as they are valuable tools to facilitate research for effective treatment of diseases. In this paper, we present the method employed to deploy an Alzheimer's disease (AD) database by Abdul Rahman et. al. on the Malaysia Research and Education Network (MYREN). The link to MYREN would facilitate resource sharing among MYREN members over a high-speed backbone network.

Wind is known as a source of power, which changes both magnitude and direction. As a result, the produced power by the generator with a wind turbine fluctuates. Therefore, the objective of this paper is to present a grid connected inverter with unity power factor for wind power applications. The current source of grid connected inverter is implemented by controlled the voltage in phase with current in order to the power flows from variable dc source to power line all time. The system characteristic of the voltage and current of grid-connected inverter as before and after synchronization to power utility are investigated by using MATLAB/SIMULINK simulation and hardware experiment. The experiment results are given, which the inverter output voltage and current are sinusoidal at 50 Hz. of frequency, the both waveform are low harmonic distortion and the current is enforced in phase with the voltage both before and after synchronization all time.

Voltage sags are major power quality problems in distribution systems. To overcome these problems, different solutions have been proposed to compensate these sags and protect sensitive loads. As a solution, Dynamic Voltage Restorers (DVRs) have been proposed to provide higher power quality. However, the quality of DVR output voltage, such as THD, is important. So, in this paper a configuration of DVR based on stacked multicell (SM) converter is proposed. The main properties of SM converter, which causes increase in the number of output voltage levels, are transformer-less operation and natural self-balancing of flying capacitors voltages. The proposed DVR consists of a set of series converter and shunt rectifier connected back-to-back. To guarantee the proper operation of shunt rectifier and maintaining the dc link voltage at the desired value, which results in suitable performance of DVR, the DVR is characterized by installing the series converter on the source-side and the shunt rectifier on the load-side. Also, the pre-sag compensation strategy and proposed synchronous reference frame (SRF) based voltage sag detection and reference series injected voltage determination methods are adopted as the control system. The proposed DVR is simulated using PSCAD/EMTDC software and simulation results are presented to validate its effectiveness.

T-way test data generators play an immensely important role for both hardware and software configuration testing. Earlier work concludes that t-way test data generator can achieve 100% coverage without having to regard for more than 6 way interactions. In this paper, we investigate whether or not such a conclusion can be applicable for reverse engineering of combinational circuits. In this case, we reverse engineer a faulty commercial eight segment display controller using our t-way test data generator in order to redesign the replacement unit. We believe that our application of t-way generators for circuit identification is novel. The results demonstrate the need of more than 6 parameter interactions as well as suggest the effectiveness of cumulative test data for reverse engineering applications.

Damping local mode and inter-area oscillations are two critical issues for optimal power flow and stability in a power system. Power system stabilizers (PSSs) are applied to damp these oscillations. Conventional algorithms of PSS design are based on classical control theory and eigen values based calculation and involve numerous mathematical calculations which may not present an accurate solution. In this paper, a particle swarm optimization (PSO) based PSS design is suggested which is based on time domain response of power system and also is robust for the overall credible disturbances in power system. Two-area (four-machine 11-bus) power system is considered as the case study in this paper. PSS parameters are obtained for four PSS connected to four generators. Finally, the effectiveness of the proposed algorithm is evaluated for damping the system oscillations during overall disturbances. The simulation results illustrate this issue.

Most educational institutions' administrators are concerned about student irregular attendance. Truancies can affect student overall academic performance. The conventional method of taking attendance by calling names or signing on paper is very time consuming and insecure, hence inefficient. Radio Frequency Identification (RFID) based attendance system is one of the solutions to address this problem. This system can be used to take attendance for student in school, college, and university. It also can be used to take attendance for workers in working places. Its ability to uniquely identify each person based on their RFID tag type of ID card make the process of taking the attendance easier, faster and secure as compared to conventional method. Students or workers only need to place their ID card on the reader and their attendance will be taken immediately. With real time clock capability of the system, attendance taken will be more accurate since the time for the attendance taken will be recorded. The system can be connected to the computer through RS232 or Universal Serial Bus (USB) port and store the attendance taken inside database. An alternative way of viewing the recorded attendance is by using HyperTerminal software. A prototype of the system has been successfully fabricated.

This paper describes implementation of peripheral interface controller (PIC) to generate pulse width modulation (PWM) signal to control the synthesize output waveform of single-phase matrix converter. This is then extended to produce an active pulse width modulation (APWM) in order to maintain input current waveform to become continuous, sinusoidal and in phase with the supply voltage and hence near unity power factor. The proposed switching control has capabilities to eliminate spike that is commonly induced with the use of inductive load.

HLW disposal is one of the largest issues to utilize Nuclear power safely. In the past study, the concept, which buffer materials and Overpacked waste were transported into underground respectively, have shown. The concept of pre-assembled engineered barrier has advantage to simplify the logistics and emplacement procedure, however there are difficulties to support heavy weight of pre-assembled package by equipment under the condition of little clearance between tunnel and package. In this study, Combination of air bearing and two degree-of-freedom wheels were suggested for transportation, and air jack was suggested for unloading and emplacement system. Also, whole system for transportation and emplacement procedure was designed, and Scale model test was examined to evaluate the feasibility of these concept and functions.

In this paper, an Intelligent Blind-Spot Sensing system is presented. This system exploits the power of sensor technology using multiple low-cost ultrasonic sensors to monitor the designated blind spots in a vehicle. In addition, an embedded Basic Stamp controller is used as the brain of the system that controls the actions of ultrasonic sensors as well as produces various warning alarms for the driver. The system uses a Fuzzy Inference System (FIS) as the main intelligence and the main decision logic of this system. Because of low-cost sensors, the readings are not very stable or precise all the time. It's the interpretation of the sensor data through the FIS which is responsible for the correctness of the decision. This system will assist the drivers in safe- maneuvering to prevent accidents. The FIS is structured to incorporate human perceptive power in making a similar decision as to whether there is danger or not‥
