Title:	A NEW HYBRID METHOD FOR MEDICAL IMAGE SEGMENTATION
Author:	NASSIMA MEZHOUD, FELLA HACHOUF
Source:	Journal of Theoretical and Applied Information Technology Vol 26. No. 1 -- 2011
Abstract	The present work is an attempt to measure the efficiency of a region method in segmenting a Medical imaging. To accomplish our study, we conceive a new hybrid clustering method which combines a neural network and a genetic training, in order to realize a fuzzy learning, and adapt a new tool for clustering called ACE (Alternating Cluster Estimation). The ACE is a new clustering model constituted of two update equations which, in contrast to classical models, are user specified and are not necessary relating to an objective function. The used neural network is composed of five layers each one, except the first, corresponds to a step of the fuzzy learning. The values optimised by the genetic training algorithm are the weights which represent the centres of membership functions characterizing linguistic terms. System input and output will be respectively, colorimetric components and cluster centres. Image data segmentation using colors space can be a valuable tool to visually assess and quantify the loss of neural. The HSV color space is used in order to, partly, get rid of the RGB space correlation. The experimental results obtained using the proposed method are encouraging.

Title:	AN IMPLEMENTATION OF ODBC WEB SERVICE
Author:	SEIFEDINE KADRY
Source:	Journal of Theoretical and Applied Information Technology Vol 26. No. 1 -- 2011
Abstract	Web applications built using .NET technologies usually access relational databases via ODBC API. This requires a database system specific ODBC driver to be installed on the application side. On the other hand, a paradigm shift is taking place in web application architectures. Future web applications will be built around Service-Oriented Architectures (SOA) where applications will be assembled using remote “web services” components. These newly assembled applications will provide functionalities using remote web services components over Internet via XML messages. Same paradigm shift will eventually apply to the data communication between applications and databases. Future applications will utilize standard “database web services” for data storage and querying requirements. Here we propose a new architectural model and present a prototype “database web service” for relational database systems. In our model, web applications do not need to deal with database drivers but leave the driver-oriented communication to a database web service. Our database web service eliminates the need for installation, maintenance, and other issues involved in maintaining ODBC drivers in distributed web application development.

Title:	MODIFIED NEW ALGORITHM FOR SEED FILLING
Author:	MALIK SIKANDAR HAYAT KHAYAL, AIHAB KHAN, SABA BASHIR, FARHAN HASSAN KHAN, SALMA ASLAM
Source:	Journal of Theoretical and Applied Information Technology Vol 26. No. 1 -- 2011
Abstract	Seed filling is basic technique of image morphology. The goal of the seed filling operations is to find the seed point and fill the object contours starting from that seed point. In image processing area, the main and most important problem is region filling. This technique is used for image analysis. There are many algorithms for filling but the proposed algorithm can be used to find seeds dynamically. Moreover, proposed algorithm is more efficient as compared to existing techniques. Seeds are found very fast. During filling process the whole region is filled inside the contour and the proposed algorithm does not cross the boundary of contour

Title:	SINGLE REPOSITORY FOR SOFTWARE COMPONENT SELECTION (SRSCS): A REUSABLE SOFTWARE COMPONENT SELECTION TECHNIQUE
Author:	YOUNAS WAHAB, MUHAMMAD IMRAN BABAR, SHAHBAZ AHMED
Source:	Journal of Theoretical and Applied Information Technology Vol 26. No. 1 -- 2011
Abstract	This work contributes a novel approach for selection of reusable components based on Functional Requirements using SRSCS (Single Repository for Software Component Selection) mechanism. Different repositories are available for reusable components and to select the best qualifying component from those repositories, customers must visit all those one by one and will select the best qualifying component based on their requirements. SRSCS selects the reusable component based on the Functional Requirements, and as it is a black box process so the source, based on which the component is qualified, is the description of the component provided by the Owner Organization. SRSCS’s main purpose is to provide a single point of the access to the customers from where they can select their required component instead of visiting all the repositories one by one. SRSCS extract information about the reusable component from different repositories, transform the description provided by the owner organization in order to classify information and remove the redundant information and store it on the single place i.e. SRSCS repository. SRSCS process consists of Extraction, Transformation, Loading and Component selection steps. In “Extraction” step information is extracted from the Owner Organization. In Transformation step, information is transformed, redundancy is removed and components are classified based on Type of the components. In Loading step the extracted information is loaded into the single SRSCS repository, and in the Component Selection step, customer sets the priorities of all information provided and the component is selected totally on the customer’s choice. SRSCS has made the selection easy with improved time efficiency as compared to other approaches. All the components are available in one place and the results are accurate.

Title:	PERFORMANCE EVALUATION OF PAGE REMOVAL POLICIES
Author:	DR. K A PARTHASARATHY
Source:	Journal of Theoretical and Applied Information Technology Vol 26. No. 1 -- 2011
Abstract	Web caching is an important technique to scale the Internet. One important performance factor of Web caches is the page replacement policies. Due to specific characteristics of the World Wide Web, there exist a huge number of proposals for cache replacement. Furthermore, the article discusses the importance of cache replacement strategies in modern proxy caches and outlines potential future research topics. In this paper we analyze effectiveness of LFU-K replacement policy for the purposes of caching on proxy servers and give the results of traces analysis taken from real proxy servers to reveal a set of properties of network traffic. On the basis of the analysis we have drawn a conclusion about expediency of usage of LFU-K policy which uses information about dynamic change of document popularity, for Web caching. The scheme of LFU-K policy is given as well as results of experiments aimed to compare its effectiveness with the most popular replacement algorithms.

Title:	INTEGRATING ICT WITH EDUCATION: DESIGNING AN EDUCATIONAL COMPUTER GAME FOR TEACHING FUNCTIONS IN UNDERGRADUATE MATHEMATICS
Author:	ROSE W. MWANGI, RONALD WAWERU, CECILIA W. MWATHI
Source:	Journal of Theoretical and Applied Information Technology Vol 26. No. 1 -- 2011
Abstract	This research seeks to look into the design process that promotes the development of an educational computer game that supports teaching and learning processes. The research specifically looks at the design of an educational computer game for teaching and learning of the topic of functions. The topic is essential in the teaching and learning of Mathematics courses such as Discrete Mathematics, Real Analysis and Calculus among others at Jomo Kenyatta University of Agriculture and Technology (JKUAT) Kenya. The computer game was developed using the Basic Unified process (BUP) which is a streamlined version of the rational unified process (RUP). This is an Object Oriented methodology mostly used for small projects with few end users. Due to the few numbers of end users we used interview method of data collection to gather requirements for the computer game. A paper prototype was used to validate the requirements. Use cases were used for both analysis and design of the game while Class diagrams and activity diagrams were purely used for the design of the game. Owens’ six top level design anatomy aided in the design of the computer game. The overall computer game design was based on Craw fords’ computer game design sequence model. The well designed and developed game met all its user requirements and was able to facilitate the teaching and learning of Functions to Bachelor of Science in Mathematics and Computer Science students who were taking Discrete mathematics in their first year of study at JKUATs’ Taita/Taveta campus. Development of heuristics for measuring interest, fun and motivation are recommendations given to aid in the evaluation of user satisfaction of educational computer games.

Title:	RECENT TRUST MODELS IN GRID
Author:	P. SURESH KUMAR, P. SATEESH KUMAR, S. RAMACHANDRAM
Source:	Journal of Theoretical and Applied Information Technology Vol 26. No. 1 -- 2011
Abstract	A grid is a framework providing services to access and manage distributed hardware and software resources. A thorough authentication is required before any requested access or operation is allowed on any resource of the grid. In particular, much risk is involved when the grid is used for e-commerce where it is necessary to share resources with unknown parties. It is difficult for a resource user on the grid to identify the quality of the resource providers. Trust is one mechanism with which one can identify the quality of the resource provider. Various models are proposed in the literature on the use of trust mechanisms in grid. This paper presents a survey on various models proposed recently on trust management in grid computing.
Keywords	Grid, Security, Trust, Grid Computing, Trust Models, Recommendation Trust, Behavior Trust.
