Research ArticleOpen accessIn the abstractMembrane Computing as a Modeling Tool for Discrete SystemsRavie Chandren Muniyandi, Abdullah Mohd. ZinProblem statement: Discrete systems have been modeled by using Ordinary Differential Equation (ODE) in which the variation of concentration of an object was modeled as continuous and deterministic manner, contrary to the real behaviors of such systems. Although, this approaches able to generate the general behavior of the system, the specific discrete processes and stochastic behaviors in the system have … …Journal of Computer Science, Vol. 7, Issue 11 · 24 Aug 2011 · 6,793 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpatient Task Mapping in Elastic Cloud using Genetic AlgorithmNawfal A. Mehdi, Ali Mamat, Hamidah Ibrahim, Shamala K. SubramaniamProblem statement: Task scheduling is the main factor that determines the performance of any distributed system. Cloud computing comes with a paradigm of distributed datacenters. Each datacenter consists of physical machines that host virtual machines to execute customers’ tasks. Resources allocation on the cloud is different from other paradigms and the mapping algorithms need to be adapted to the new … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 8,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteractive Computing Framework for Engineering ApplicationsJovana Knezevic, Jerome Frisch, Ralf-Peter Mundani, Ernst RankProblem statement: Even though the computational steering state-of-the-art environments allow users to embed their simulation codes as a module for an interactive steering without the necessity for their own expertise in high-performance computing and visualisation, e.g., these environments are limited in their possible applications and mostly entail heavy code changes in order to integrate the existing code. Approach: In this … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,207 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. Essentially, middleware is … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Flexible and Reliable Architecture for Mobile Agent SecurityGhossoon M.W. Al-SaadoonProblem statement: Wireless application protocol is a protocol that makes it possible to surf the Internet from a cellular phone or other handheld wireless. Many of us that surf the Internet from home with a 56 kbps modem think that it is slow and a cell phone only uses 9.6 kbps so WAP has to take the lesser bandwidth into … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncremental DataGrid Mining Algorithm for Mobility Prediction of Mobile UsersU. Sakthi, R.S. BhuvaneswaranProblem statement: Mobility prediction is the important issue in Personal Communication Systems (PCS). Mobile users moving logs are stored in data grid located in different locations. Distributed data mining algorithm is applied on this moving logs to generate the mobility pattern of mobile users. As new moving logs are added to the data grid, existing mobility pattern becomes invalid and … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 6,775 accessesView PDFCite

Research ArticleOpen accessIn the abstractNimble Protein Sequence Alignment in Grid (NPSAG)K. Somasundaram, S. RadhakrishnanIn Bio-Informatics application, the analysis of protein sequence is a kind of computation driven science which has rapidly and quickly growing biological data. Also databases used in these applications are heterogeneous in nature and alignment of protein sequence using physical techniques is expensive, slow and results are not always guaranteed/accurate. So this application requires cross-platform, cost-effective and more computing power … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,921 accessesView PDFCite
