Title:	A METHOD FOR QUALITY POWER PROVIDER TO OPERATE IN DISTORTED SUPPLY CONDITION
Author:	K.CHANDRASEKARAN, K.S.RAMA RAO
Source:	Journal of Theoretical and Applied Information Technology pp 66 - 75 Vol 30. No. 2 -- 2011
Abstract	Power Quality is a major concern within power industry and consumers. Poor quality of supply will affect the performance of customer equipment such as computers, microprocessors, adjustable speed drives, power electronic controllers, life saving equipment in hospitals, etc. and result in heavy financial losses to customers due to loss of production or breakdown in industries or loss of life in a hospital. The two major power quality disturbances are voltage sag and harmonic distortion. In this paper, a Quality Power Provider (QPP) based on voltage source inverter is modeled by simulation to compensate the power quality disturbances such as voltage sag and voltage harmonics in the distorted supply condition. The phase locked loop (PLL) is an important control unit of the QPP control scheme. To obtain accurate phase information and frequency of the input supply, the dqPLL method has been proposed. Simulation results based on MATLAB and PSCAD software are presented to verify the performance of the proposed QPP. QPP has improved the quality of power supply at the sensitive load end.

Abstract	The development of Yet Another Agile Methodology (YAAM) has added to the list of Agile software processes which is a novel software development process introduced for use in modern software development. In this paper, YAAM is deployed in E-Bookshop use case scenario to substantiate the development benefit claims made during the introduction of the software process. E-Bookshop Scenario was selected due to its varying complexity concerns which are suitable in testing various areas that were perceived to be difficult to handle using other software processes. The deployment is implemented using open source tools and languages.

Title:	AN INTELLIGENT TECHNIQUE TO MULTI-SENSOR DATA FUSION IN TARGET TRACKING
Author:	ASHRAF ANWAR, SULTAN ALJAHDALI
Source:	Journal of Theoretical and Applied Information Technology pp 86 - 97 Vol 30. No. 2 -- 2011
Abstract	Combining the results of multiple sensors can provide more accurate information than using single sensor. In this paper, we develop fuzzy clustering approach to data association and track fusion in multi-sensor multi-target environment. The proposed approach uses the fuzzy clustering means algorithm to get the degree of membership of new tracks to existing tracks. Unlike existing approaches, in which the membership functions are fixed a priori (determined empirically), we generate optimal membership functions from the data using the fuzzy clustering means algorithm. More specifically, the values of the membership functions change according to the relative positions of the targets with respect to the sensors; this adaptation to the current state of the environment leads to far better/accurate results. Furthermore, our proposal can handle different types of information without excessive computation; indeed, it reduces considerably the computational complexity compared to existing schemes.

Title:	A COMPARISON OF BLOOD DONOR CLASSIFICATION DATA MINING MODELS
Author:	SHYAM SUNDARAM, SANTHANAM T
Source:	Journal of Theoretical and Applied Information Technology pp 98 - 101 Vol 30. No. 2 -- 2011
Abstract	This study uses decision trees derived from data mining modeling techniques to examine the blood donor classification. The primary goal of this classification model is provide the capability to determine voluntary blood donorship based on blood donation patterns. In specific a comparison is made of two models (one based on a specific donation drive versus the regular voluntary donor patterns) based on a standard data set for blood transfusion. The enhancement of attributes that help enable the determination of voluntary donorship is also a suggested value addition The paper discusses comparison of donorship models using the classification algorithms of data mining which enable representation as decision trees. The analysis provides insight into the development of donor classification which enable blood banks to determine the kinds of donor profiles and manage blood donorship related activities like recruitment and campaigns for blood donations.

Title:	THREE PHASE CONTROL FOR PWM-SWITCHED AUTOTRANSFORMER VOLTAGE-SAG COMPENSATOR BASED ON PHASE ANGLE ANALYSIS
Author:	MUHAMAD MANSOR, NASRUDIN ABD. RAHIM
Source:	Journal of Theoretical and Applied Information Technology pp 102 - 108 Vol 30. No. 2 -- 2011
Abstract	Enhancing compensating capability is essential in a voltage-sag compensator. It involves two main aspects, first, sag detection technique and second, voltage sag compensator. Many detection techniques have been introduced to measure and to detect voltage sag, such as RMS-Value Evaluation and Peak-Value Evaluation. Unfortunately, most of the techniques require a delay for sag to be detected then compensated, whereas immediate sag detection is vital to improvement of transient performance. Presented is a three-phase PWM-switched autotransformer voltage-sag compensator that is based on AC-AC converter and that uses the proposed three phase controller based on Phase Angle Analysis as the detection technique. The significant advantage of this detection technique is the detection time. It is capable of detecting and compensating voltage sag the moment sag occurs without delay. Its effectiveness and capability were verified via MATLAB/Simulink simulation

Title:	FEASIBILITY STUDY OF USING WIND TURBINES WITH DIESEL GENERATORS OPERATING AT ONE OF THE RURAL SITES IN JORDAN
Author:	DR ATEF.S. AL-MASHAKBEH
Source:	Journal of Theoretical and Applied Information Technology pp 109 - 114 Vol 30. No. 2 -- 2011
Abstract	Jordan is one of the countries, which suffer from energy resources shortage. Therefore, it is entirely dependent on imported oil, form neighboring countries. The exploitation of green sources is encouraged to reduce the environmental pollution and combat the global warming of the planet. Wind is a natural renewable source energy that has a significant potential in Jordan. This paper introduces a feasibility study of integrating wind energy with diesel plant for a rural site in a remote southern of Jordan called "Rass Alnaqab". The data concerning the load, the national grid, the price of energy and the average wind speed at that site are calculated. The Weibull distribution technique was then used to analyze the wind data. A simple calculation was done to illustrate the visibility of integrating wind energy with diesel sets. The environmental factors have been calculated.

Abstract	The concept of digital archives to store long term data has readily increased in past few years. Many social, business and government organizations store their data in digital archives for long time span with many challenges along with its advantages. One of the major and most common problem is to ensure the integrity of data stored in digital archives. Usage of hash algorithms is solution to provide integrity in digital archives. Lots of hash algorithms are available now days but the problem is that usually the organizations are short of resources especially time and memory, so they always look for such algorithm that consumes the least amount of resources providing the security at maximum. So in this work the most commonly used hash algorithms are evaluated for their performance on the basis of time, memory and efficiency with variable data object size. SHA-1, MD-5, RIPEMD-160 and HAVAL-256 are evaluated for performance, being the most commonly used hash algorithms. Results show that MD-5 consume least amount of resources with somewhat questionable security, SHA-1 and RIPEMD-160 are more consistent in behavior with a compromising amount of resource usage and security and HAVAL-256 provides best security with high rate of resource usage.

Abstract	In this paper, we give some theoretical results, for the index WienerW, degree distance DD and the hyper-Wiener index WW of a graphG, according to d_G (k)(The number of pairs of vertices of G that are at distance), and the diameter of G. We accomplish this by firstly, giving another proof of the inequality for the planar graphs with nvertices:W(En)≤W(Cn)≤W(Pn)[6], with E_n is a maximal planar graphC_n is a planar graph and P_n is a path planar graph. Secondly, we will apply the theoretical results for some graphs with diameter equals two, as Fan planar graphF_n, Wheel planar graph W_n, maximal planar graph E_n and the butterfly planar graph B_n, and some particularly graphs with diameter greater than two, as the cycle planar graphC_n and the Sunflower planar graph S_n
