Title:	EFFECT OF LIGHTNING IMPULSE VOLTAGE ON THE PERFORMANCE OF 1-PHASE GAS INSULATED BUSDUCT IN THE PRESENCE OF METALLIC PARTICLE CONTAMINATION WITH SF6/N2 GAS MIXTURES

Abstract	SF6 is the main mode of insulation in a GIS. However, in recent years, the future use of SF6 has been debated throughout the world in spite of it having all the desirable properties of a good insulating and arc quenching medium. Sulfur hexafluoride (SF6) has been used as a gaseous dielectric (insulator) in high voltage equipment since the 1950s. It is now known that SF6 is a potent greenhouse warming gas with one of the highest global warming potentials (GWP) known. In the presence of metallic contamination can seriously reduce the insulation performance of a GIS. Particularly the influence of free metallic particles has been regarded as an important issue for many years, since free particles are considered to be hazardous because of the possibility of initiating a voltage breakdown. Transient over voltages due to lightning voltages cause steep build up of voltage on transmission lines and other electrical apparatus. Therefore GIS must be able to withstand such voltages without breakdown of insulation. As GIS operates under power frequency voltages. Lightning impulse voltage of 1050kV superimposed on power frequency voltages of 75kV,120kV and 132kV are applied to 1-Ф GIB and the maximum movement of Cu, Al and Silver contaminants are obtained with and without Monte-Carlo technique for SF6 gas SF6/N2 gas mixtures as dielectric medium.

Title:	FAULT TOLERANCE OF DISTRIBUTED LOOPS
Author:	Abdel Aziz Farrag
Source:	Journal of Theoretical and Applied Information Technology Vol 20. No. 1 -- 2010
Abstract	Distributed loops are highly regular structures that have been applied to the design of many locally distributed systems. This family of networks includes many important configurations such as rings and circulant graphs, for examples. In this paper, we examine the problem of extending a (unidirectional) distributed loop so as to tolerate any given number of node failures. We study this problem when the parameters that define the loop are given numerically (as constants) or symbolically (as variables). We demonstrate our formulation by developing (fault tolerant) solutions for daisy-chain networks. Our results show that the solutions obtained are efficient (i.e., either optimal or nearly optimal).
Keywords	Networks, graphs, distributed loops, fault-tolerant solution

Title:	DIRECT TORQUE CONTROL OF INDUCTION MOTOR BASED ON ARTIFICIAL NEURAL NETWORKS WITH ESTIMATE AND REGULATION SPEED USING THE MRAS AND NEURAL PI CONTROLLER
Author:	MY.R.DOUIRI, T.NASSER, A.ESSADKI, M.CHERKAOUI
Source:	Journal of Theoretical and Applied Information Technology Vol 20. No. 1 -- 2010
Abstract	This paper presents an improved direct torque of induction machine based on artificial neural networks. This intelligent technique was used to replace, on the one hand the conventional comparators and the selection table in order to reduce torque ripple, flux and stator current, on the other hand and the classic integral proportional (PI) in order to increase the response time period of the system, to optimize the performances of the closed loop control, and to adjust the parameters of the regulator to changes in the reference level. Then we estimated the rotor speed using the Model Reference Adaptive Control “MRAS” method based on measurements of electrical quantities of the machine. The validity of the proposed methods is confirmed by the simulation results.
Keywords	Induction Motor, Direct Torque Control, Direct Torque Neural Control, Neural PI controller, Model Reference Adaptive Control (MRAS)

Abstract	Experiential marketing provides customers an opportunity to engage and interact with brands, products, and services in sensory ways in today’s competitive markets. This research demonstrates how experiential marketing fits in with the current consumer behavior and attitudes through cell phone usage on Turkish consumers. In the research, the steps and elements of experiential marketing will be clearly defined. A questionnaire is prepared content with this research and is applied on 612 cell phone users as participants from various regions of Turkey. Sampling of the research consists of 612 participants of 18-65 age groups. The research data are analyzed in the program of SPSS 10.0 and t test, factor analysis, frequency analysis, correlation analysis and variance analysis are performed. The study indicates that the subjects on which the participants show attitude at higher level are related with the brand experience. In addition to this, it is seen that the consumers evaluated the products in the frame of the social status symbolized in their cell phone preferences in the experience of association.
Keywords	Experiential marketing, hedonism, advertising, brands, cell phone

Abstract	Wireless Sensor Networks (WSN) is a recent advanced technology of computer networks and electronics. The WSN increasingly becoming more practicable solution to many challenging applications. The sensor networks depend upon the sensed data, which may depend upon the application. One of the major applications of the sensor networks is in military. So security is the greatest concern to deploy sensor network such hostile unattended environments, monitoring real world applications. But the limitations and inherent constraints of the sensor nodes does not support the existing traditional security mechanisms in WSN. Now the present research is mainly concentrated on providing security mechanism in sensor networks. In this context, we analysis security aspects of the sensor networks like requirements, classifications, and type of attacks etc., in this survey paper

Abstract	This research is intended to develop a model of multimedia application, particularly a puzzle game for Interactive Multimedia Course. This model should encourage students to integrate all information resources to develop a multimedia application particularly puzzle game. The puzzle game application generates input and processed data as a server-side with Adobe Flash. Flash is a powerful and dynamic front-end and great interface for server-side applications. PHP can launch server-side script using Flash as a front-end to pass data and variables between the MySQL database, PHP, and Flash to manage databases. Subjects of the research are computer education, visual communication, and software engineering experts in preliminary field testing, the informatics students at School of Multimedia Technology Cendekia Abditama for implementation of the revised model in the main field testing.

Title:	A METHOD FOR REQUIREMENTS MANAGEMENT IN DISTRIBUTED EXTREME PROGRAMMING ENVIRONMENT
Author:	Ali Akbar Ansari, Sayed Mehran Sharafi, Naser Nematbakhsh
Source:	Journal of Theoretical and Applied Information Technology Vol 20. No. 1 -- 2010
Abstract	Both Distributed Software Development (DSD) and eXtreme Programming (XP) approaches have gained significant Popularity. Both DSD and XP method are growing trends as software business requires quicker quality production at a cheaper price. Requirement Management (RM) is not easy to perform even under the best of circumstances and it becomes more difficult when performed globally because of the nature of distributed development projects and the diversity of stakeholders. This article presents an investigation of the possibility to integrate Requirement Management in Distributed eXtreme Programming. One reason for integrating RM with DXP was that XP emphasizes lightweight documentation in XP based development. We propose the development of model and tool for executing RM in DXP that are required for proper software engineering and that activity should not restrict the efficient execution of XP method in DSD.
Keywords	Distributed Software Development (DSD), eXtreme Programming (XP), Requirements Management (RM)

Abstract	Mobile wireless communication is the fastest growing segment of the communication industry. However, it is faced with the challenge of providing reliable high-speed communications due to channel impediments which change over time in unpredictable ways. This paper presents a joint decision feedback equalizer and diversity combiner called adaptive diversity combining to combat the fast time-varying nature of mobile radio channels. The results obtained showed that the proposed technique is robust for signal transmission over mobile radio channels.
