Research ArticleOpen accessIn the abstractMobile Agents in Heterogeneous Networks: A Look on PerformanceR. B. Patel, Neeraj GoelMobile agents can be seen as a new paradigm for distributed computing. One characteristic of mobile agents is their autonomy and pro-activity. This article present a framework designed on top of PMADE (Platform for Mobile Agent Distribution and Execution) to support our research in this domain. Our framework consists of three modules. The Map Module collects information on the available … …Journal of Computer Science, Vol. 2, Issue 11 · 30 Nov 2006 · 6,490 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelling and Forecasting Volatility of Returns on the Ghana Stock Exchange Using Garch ModelsFrimpong Joseph Magnus, Oteng-Abayie Eric FosuThis paper models and forecasts volatility (conditional variance) on the Ghana Stock Exchange using a random walk (RW), GARCH(1,1), EGARCH(1,1), and TGARCH(1,1) models. The unique ‘three days a week’ Databank Stock Index (DSI) was used to study the dynamics of the Ghana stock market volatility over a 10-year period. The competing volatility models were estimated and their specification and forecast … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 7,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractOperation of an SLA-aware Grid FabricMatthias HovestadtResearch on Grid Computing started under purely technical questions of how to realize the virtualization of distributed resources. Now, the commercial user should be attracted to use the Grid. Future applications of the Next Generation Grid will demand for flexible negotiation mechanisms supporting various ways of Quality-of-Service (QoS) guarantees. In this context a Service Level Agreement (SLA) is a powerful … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractSplitting Technique Initialization in Local PCAAlok Sharma, Kuldip K. Paliwal, Godfrey C. OnwuboluThe local Principal Component Analysis (PCA) reduces linearly redundant components that may present in higher dimensional space. It deploys an initial guess technique which can be utilized when the distribution of a given multivariate data is known to the user. The problem in initialization arises when the distribution is not known. This study explores a technique that can be easily … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,719 accessesView PDFCite

The application provides useful insights to address crucial points such as user interests into a particular page, server load balancing, Web site reorganization, clustering of similar browsing patterns, classification of user profiles, content caching or … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,783 accessesView PDFCite
Research ArticleOpen accessIn the abstractResidual Defects in Silicon Implanted with Boron and Phosphorous IonsM. JadanAccumulation of radiation defects in Si implanted with B+ or P+ ions, and formation of the residual extended defects (dislocation loops, rod-like defects) in the process of successive thermal treatment have been studied. The anomalies observed in the formation of the extended defects are associated with the elastic stresses in the damaged regions affecting the process of radiation defects clustering. …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Genotyping of Mycobacterium tuberculosis Isolates from TurkeyBerrin Gencer, Thomas M. ShinnickTo survey the circulating strains of Mycobacterium tuberculosis in Turkey, all clinical isolates (381 patients) recovered in laboratories in six cities during one-month periods were collected and typed by IS6110-DNA fingerprinting and spoligotyping. Drug susceptibilities were also determined. About 23% of the isolates were resistant to one or more drugs and about 4% were multidrug resistant (i.e., resistant to at … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,731 accessesView PDFCite
