Title:	TWO PHASE HEAT TRANSFER STUDIES ON LIQUID-LIQUID SYSTEM IN TUBE SIDE SHELL AND TUBE HEAT EXCHANGER
Author:	V. ALAGESAN, S. SUNDARAM
Source:	Journal of Theoretical and Applied Information Technology pp 107 - 117 Vol 32. No. 2 -- 2011
Abstract	Heat transfer studies on immiscible systems are vital in petrochemical and allied industries. Two phase systems water – oleic acid and water – palm oil of varying compositions were experimentally studied in a 1:2 shell and tube heat exchanger. The data fitted to an equation of the form NNu= n NRek with an average absolute deviation ranging between 3.882 and 9.921 percent where n and k are functions of composition of the systems studied. The two phase multiplier,L, was related to Lockhart Martinelli(L-M) parameter, χtt2, using the two phase data and a correlation L = b* χtt2 / c+ χtt2 was established. The two phase heat transfer coefficient h2 for both systems were recalculated based on the above correlation and found that water as better reference fluid gave the least error ranging between 2.193 and 6.313 percent for both the systems.

Abstract	Extracting previously unknown patterns from huge volume of data is the primary objective of any data mining algorithm. In recent days there is a tremendous growth in data collection due to the advancement in the field of information technology. The patterns revealed by data mining algorithm can be used in various domains like Image Analysis, Marketing and weather forecasting. As a side effect of the mining algorithm some sensitive information is also revealed. There is a need to preserve the privacy of individuals which can be achieved by using privacy preserving data mining. In this paper we propose a new approach to preserve sensitive information using fuzzy logic. First we perform clustering on the original data set then we add noise to the numeric data using a fuzzy membership function that results in distorted data. Set of Clusters generated using the distorted data is also relative to the original cluster as well as privacy is also achieved. It is also proved that the number of iterations for performing the clustering process is less in our approach when compared with the traditional approach.

Abstract	Active Magnetic Bearings (AMB) have many advantages such as no friction loss, no abrasion, lubrication- free quality, and used for high rotational speed applications. A complete AMB system consists of an actuator, power amplifier, a rotor position sensor and a control system. In this paper, a closed loop decentralized Fuzzy Logic controller for Active magnetic Bearings is designed. For the numerical evaluation of control algorithm a MIMO (multiple input multiple output) mathematical model of the controlled plant is determined. The majority of industrial applications of active magnetic bearings were still based on conventional PID control system. The proposed control design is based on rule based procedure. It has been shown, that the presented FL control guarantees satisfactory high damping, low parameter variations and measurement noise of the overall system. The designed FL controller is able to maintain the rotor in center position in the final steady state. Simulations are provided to illustrate the performance of the controller.

Abstract	Context Based Binary Arithmetic Coding (CBAC) is a part of JZ profile of Audio Video Coding Standard (AVS).The goal of this paper is to present the efficient hardware based binary arithmetic coder which is the main part of binarisation involved in CBAC of AVS. This paper explains about the efficient arithmetic coding involved in the video transcoding. The major concerns of using JZ profile of AVS is movie compression for high-density storage and relatively higher computational complexity can be tolerated at the encoder side to provide higher video quality. This arithmetic coder avoids the slow multiplication, here the traditional arithmetic calculation is transformed to software domain using log. The proposed arithmetic engine will give high compression gain and an efficient coding design for handling the high resolution video sequence. This is used for the effective pipelining process and increase the overall processing speed. The implementation of arithmetic coder in CABAC (Context Adaptive Binary Arithmetic Coding) architecture is satisfying the CBAC feature. The study of this paper is required to know about the process of efficient AC(arithmetic coding) and the hardware based arithmetic engine in CBAC. The CBAC engine is implemented on Xilinx Virtex-5 ML501 Board. The synthesis and simulation results are presented. The proposed architecture can work with the 31.384MHz rate.

Abstract	Plagiarism is a form of academic misconduct. It has increased rapidly because it is now quick and easy to reach data and information through electronic documents and the Internet. The problem occurs when found documents content is illegal and without permission or citation, this problem is known as plagiarism. One of the major challenges is to detect the plagiarism and illegal copy. This paper discusses a new representation method for text documents called text graph-based representation. The proposed method does not represent the content of a text document as a graph only, but also captures the underlying semantic meaning in terms of the relationships among its concepts in order to defeat the difficulty which the traditional plagiarism detection systems face with some kinds of plagiarism such as complicated plagiarism in which users can reword the plagiarized part or replace some words by their synonyms. The experiments have been carried out using PAN-PC-09 standardization of plagiarism detection corpus. The results showed that our method remarkably outperforms the modern methods for plagiarism detection.

Title:	TRANSITION BASED INPUT TEST VECTOR PARTITIONING FOR LOW POWER SWITCHING ACTIVITY
Author:	S.SARAVANAN, HAR NARAYAN UPADHYAY
Source:	Journal of Theoretical and Applied Information Technology pp 146 - 151 Vol 32. No. 2 -- 2011
Abstract	Present complexity of System on Chip (SOC) has brought new challenges in low power design and testing. This shows that huge test pattern and its corresponding switching activity are one of the major problems. Due to this large number of test patterns the data transition time is also increased. More switching is also proportional to more number of transitions. This paper considers the problem of switching activity in scan based test pattern. This proposed approach is based on reducing the huge switching activity by partitioning the test vectors into groups. The number of transition is identified in each partition group. The groups having zero transition have lesser switching activities, so they are not considered equally with transition group for testing. Thus the test run time and number of switching is minimized. This in turn reduces the power consumption for testing. The proposed technique tested on ISCAS89 shows the significant reduction in overall switching activity of the test pattern.

Source:	Journal of Theoretical and Applied Information Technology pp 152 - 159 Vol 32. No. 2 -- 2011
Abstract	The purpose of this study is to identify Knowledge Management (KM) dominant success factors in an academic institute. In today’s competitive business environment, KM is increasingly recognized as a significant factor in gaining a competitive advantage. To obtain such competitive advantage, companies must know how to manage organizational knowledge effectively and optimize the knowledge processes within an organization. KM success factors have been investigated in many studies, but there has been no sufficient examination of the dominant success factors of KM in academic institution. There is a need to find dominant factors that can be used to make an accurate assessment of the KM success or effectiveness. A model for KM in academic institution that based on Structural Equation Model is constructed at the end of the study. The proposed model contributes to a better identification of KM dominant success factors; and enables managers of academic institution to have a better understanding of how to improve the management of knowledge in their institution.

Title:	INTER SPACE LOCAL BINARY PATTERNS FOR IMAGE INDEXING AND RETRIEVAL
Author:	DILKESHWAR PANDEY, RAJIVE KUMAR
Source:	Journal of Theoretical and Applied Information Technology pp 160 - 168 Vol 32. No. 2 -- 2011
Abstract	In this paper, inter space local binary pattern (ISLBP) algorithm for content based image retrieval (CBIR) is proposed. First the image is separated into red(R), green(G), and blue(B) color spaces, and these are used for inter space local binary patterns (ISLBP), which are evaluated by taking into consideration of local difference between the center pixel and its neighbors by changing center pixels of one color space with other color space. Local binary pattern (LBP) extracts the information based on distribution of edges in an image. Finally, inter LBP histograms are constructed between the color spaces for image retrieval. The experimentation has been carried out for proving the worth of our algorithm. It is further mentioned that the databases considered for experiment viz. Corel 1000 and MIT VisTex databases. The results after being investigated show a significant improvement in terms of their evaluation measures as compared to LBP on RGB spaces separately.

Author:	N.PRIYADHARSHINI, S.SUBASREE
Source:	Journal of Theoretical and Applied Information Technology pp 179 - 188 Vol 32. No. 2 -- 2011
Abstract	Wireless Sensor Networks utilize large numbers of Wireless Sensor nodes to forward information from source to destination. Wireless Sensor Nodes are battery-powered devices. Energy saving is always vital to maximize the lifetime of Wireless Sensor Network. Recently, there are many Routing Protocols have been designed and proposed for Wireless Sensor Networks to improve its performance in terms of Communication Time, Residual Energy and Energy Consumption and also these protocols addressed Reliability and Shortest path. In this paper, this research work has implemented various Routing Protocols namely Power Efficient Data Gathering and Aggregation Protocol (PEDAP), Power Efficient Data Gathering and Aggregation Protocol-Power Aware (PEDAP-PA), Energy Efficient Spanning Tree approach (EESR), and Localized-Power Efficient Data Gathering and Aggregation Protocol (L-PEDAP) are studied thoroughly. From the experimental results, it is revealed that L-PEDAP outperforms PEDAP, PEDAP-PA and EESR in terms of Bandwidth, Resource Utilization and Communication Reliability. However, L-PEDAP fails to minimize the Energy Consumption and Communication Time due to Dynamic Routing Mechanisms. The PEDAP achieves less Communication Time to forward packets to destination. However, it fails to achieve Power-Aware Reliable Communication. From this analysis, it is observed that for faster communication, PEDAP could be used and for reliable communication with high bandwidth utilization, L-PEDAP is the best Routing Protocol in Wireless Sensor Networks.
