Research ArticleOpen accessIn the abstractParallel Approaches for Intervals Analysis of Variable Statistics in Large and Sparse Linear Equations with RHS RangesPeerayuth CharnsethikulThis study proposes an algorithm capable of working in parallel for solving large and sparse linear equations under given right hand side (RHS) ranges. A comparative study to the direct linear programming method is reported theoretically, computationally and discussed. Moreover, the approach can be adapted for the system under domain decompositions structure leading to a better efficiency experimentally. …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining the Optimal Software Rejuvenation Schedule via Semi-Markov Decision ProcessHiroyuki Eto, Tadashi DohiSoftware rejuvenation is a preventive and proactive maintenance policy that is particularly useful for counteracting the phenomenon of software aging. In this study we consider an operational software system with multiple degradations and derive the optimal software rejuvenation policy minimizing the expected operation cost per unit time in the steady state, via the dynamic programming approach. Especially, we show analytically … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeta Architecting: Towered a New Generation of Architecture Description LanguagesAdel Smeda, Tahar Khammaci, Mourad OussalahThe techniques of meta-modeling and meta-levels have become a mature concept and have been largely used to solve real problems in programming languages, distributed environments, knowledge representation, or data bases. In this article it is shown how the same techniques can be applied in component-based software architecture. It also shown the need to propose mechanisms of reflexivity within the domain … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Note towards Reshaping Java's FeaturesN. S. Kutti, Z. A. Al-Khanjari, H. A. Ramadhan, J. FiaidhiProgramming Languages continually go through the refinement process due to several findings such as lack of robustness, lack of flexibility, lack of simplicity and lack of standard. This may require pruning undesirable features, sometimes softening of hard nature of some features and adding new features to improve the scope of the languages. Recently Java has emerged as a refined language … …Journal of Computer Science, Vol. 1, Issue 4 · 30 Dec 2005 · 6,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractSemi Strongly E-Convex FunctionsE. A. Youness, T. EmamIn this study a new class of functions, called semi strongly E-convex functions, and generalized semi strongly E-convex functions are defined .We discuss some their basic properties and obtain sufficient optimality criteria for nonlinear programming problems involving these functions. …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,813 accessesView PDFCite
