Research ArticleOpen accessIn the abstractA Fuzzy Based Mechanism For Allocation of Grid ResourcesM. Poonguzhali, S. ShanmugavelOne of the main challenges in Grid computing is efficient allocation of resources (CPU-hours, network bandwidth) to the tasks submitted by users. In our previous work a technique to allocate resources in a grid environment using predicted data has been proposed. We propose utilization of the predicted data the resources were classified into three types; they are permanent resources, semi-permanent … …Journal of Computer Science, Vol. 9, Issue 5 · 23 May 2013 · 6,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrid Voltage Stability Enhancement Using Photovoltaic Based Static Synchronous CompensatorSubhransu Sekhar Dash, Arun Bhaskar Mayilvaganan, Venkatesh VenkataramananToday, we are mostly dependent on non renewable energy that have been and will continue to be a major cause of pollution and other environmental degradation. Because of these problems and our dwindling supply of petroleum, finding sustainable alternatives is becoming increasingly urgent. Perhaps, the greatest challenge is in devising a sustainable future, which relies on integration and control of … …Journal of Computer Science, Vol. 9, Issue 3 · 17 Apr 2013 · 6,861 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Fault Tolerant Scheduling Approach for Computational GridP. Keerthika, N. KasthuriGrid computing serves as an important technology to facilitate distributed computation computational grids solve large scale scientific problems using heterogeneous geographically distributed resources. Problems like dispatching and scheduling of tasks are considered as major issues in computational grid environment. The Grid Scheduler must select proper resources for executing the tasks with less response time. There are various reasons such as … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 5 Jan 2013 · 6,995 accessesView PDFCite

Murali BhaskaranGrid provides an infrastructure for sharing geographically distributed heterogeneous resources to process many applications and mainly used for solving scientific problems that requires more computation time. Problem statement: Grid is a dynamic environment, where the resources may join or leave the environment at any time and the jobs also arrives at different intervals of time. To meet the demands and … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 6 Jul 2012 · 6,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fault Tolerant Resource Allocation Architecture for Mobile GridS. Thenmozhi, A. Tamilarasi, P. T. VanathiProblem statement: In order to achieve high level of reliability and availability, the grid infrastructure should be fault tolerant. Since the failure of resources affects job execution fatally, fault tolerance service is essential to satisfy QoS requirement in grid computing with respect to mobile nodes. Approach: We propose a fault tolerant technique for improving reliability in mobile grid environment considering … …Journal of Computer Science, Vol. 8, Issue 6 · 7 Apr 2012 · 7,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractContact with Nature and Children’s Wellbeing in Educational SettingsGiuseppe Carrus, Sabine Pirchio, Ylenia Passiatore et al.Problem statement: The study explores the role of the spatial-physical features of the environment for the functioning of educational institutions. Previous research in the field of environmental psychology showed how physical characteristics of learning environments might be linked to positive or negative outcomes in terms of learning attitudes and behaviors. In particular, there is consistent empirical evidence showing that contact … …Journal of Social Sciences, Vol. 8, Issue 3 · 26 Mar 2012 · 14,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Multi-Agent Based Data Replication Mechanism for Mobile GridT. Senthilnathan, T. PurusothamanProblem statement: In Mobile grid, the mobile devices can be effectively incorporated in to the Grid. It enables both the mobility of the users requesting access to a fixed grid and the resources that are themselves as part of the grid. There are number challenging issues for mobile grid; such as connectivity, availability, maintainability, consistency and fault tolerance. This study … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 13 Feb 2012 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Stringent Authorization using Principles and Policy for Grid ComputingA. R. Jayasudha, T. PurusothamanProblem statement: The current information security mechanisms are insufficient to address authorization issues. The access control models today are mostly static and they are not wellsuited for the service-oriented environments where information access is dynamic in nature. Traditional authorization security techniques do not directly address these concerns as they primarily use access control lists for authorization, where the user whose … …Journal of Computer Science, Vol. 7, Issue 8 · 8 Aug 2011 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Approach for 3D Range Image Segmentation using Gradient MethodDina A. Hafiz, Walaa M. Sheta, Sahar Bayoumi, Bayumy A.B. YoussefProblem statement: Segmentation of 3D range images is widely used in computer vision as an essential pre-processing step before the methods of high-level vision can be applied. Segmentation aims to study and recognize the features of range image such as 3D edges, connected surfaces and smooth regions. Approach: This study presents new improvements in segmentation of terrestrial 3D range images … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 19,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Based Middleware for Grid ComputingS. Muruganantham, P. K. Srivastha, KhanaaProblem statement: "Grid" computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications and, in some cases, high-performance orientation. The role of middleware is to ease the task of designing, programming and managing distributed applications by providing a simple, consistent and integrated distributed programming environment.
