Research ArticleOpen accessIn the abstractA Cooperative Intelligent Decision Support System for Contingency ManagementAbdelkader ADLATraditional Decision Support Systems (DSS) give not enough possibilities of intervention to the user. These systems are reduced to an insular and very technical state in which the objective is not support decision but to dump data on the screen in the hope that the user will know what to do with. In complex situations, decision is not structured and … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractMEDiator: A Tool for Automatic Management of Event DomainsMarkus Aleksy, Lisa Köblitz, Martin SchaderIn this study, we describe our software component MEDiator. Our development is based on OMG’s Management of Event Domains specification. It allows the efficient management and simplified operation of different CORBA Notification Services running concurrently. After a brief introduction into the specifications of the Notification Service and the Management of Event Domains, we describe their architecture and discuss the most … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,492 accessesView PDFCite
Research ArticleOpen accessIn the abstractPredictive Autonomicity of Web Services in the MAWeS FrameworkEmilio P. Mancini, Massimiliano Rak, Roberto Torella, Umberto VillanoIn Web Services designs classical optimization techniques are not applicable. A possible solution to guarantee critical requirements is the use of an autonomic architecture, able to auto-configure and to auto-tune. This study presents MAWeS (MetaPL/HeSSE Autonomic Web Services), a framework whose aim is to support the development of self-optimizing predictive autonomic systems for Web service architectures. It adopts a simulation-based … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 7,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractHighly Efficient Elliptic Curve Crypto-Processor with Parallel GF(2m) Field MultipliersTurki F. Al-Somani, M. K. Ibrahim, Adnan GutubThis study presents a high performance GF(2m) Elliptic Curve Crypto-processor architecture. The proposed architecture exploits parallelism at the projective coordinate level to perform parallel field multiplications. In the proposed architecture, normal basis representation is used. Comparisons between the Projective, Jacobian and Mixed coordinate systems using sequential and parallel designs are presented. Results show that parallel designs using normal basis gives … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractDigital Hardware Implementation of a Neural System Used for Nonlinear Adaptive PredictionHassène Faiedh, Chokri Souani, Kholdoun Torki, Kamel BesbesNeural networks have been widely used for many applications in digital communications. They are able to give solutions to complex problems due to their nonlinear processing and their learning and generalization. Neural networks are one of the key technologies for the communication domain and accordingly a special effort may be expected to be paid to real time hardware implementation issues. … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,763 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Control for Self-erecting Inverted Pendulum Via Adaptive Neuro-fuzzy Inference SystemA. A. Saifizul, Z. Zainon, N. A.Abu Osman et al.A self-erecting single inverted pendulum (SESIP) is one of typical nonlinear systems. The control scheme running the SESIP consists of two main control loops. Namely, these control loops are swing-up controller and stabilization controller. A swing-up controller of an inverted pendulum system must actuate the pendulum from the stable position. While a stabilization controller must stand the pendulum in the … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,322 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Online Website for Tutoring and E-Examination of Economic CourseIbrahiem M.M. EL Emary, Jihad A.A. Abu Al SondosThis study aimed to present a novel software tool can be used for online examination and tutorial application of the syllabus of economic course. Also, among the main interests of this paper is to produce a software through it we make sure that students have studied all the concepts of economics. So, the proposed software is structured from two major … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 6,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Update Policy for Proactive Management of Deadline Miss Ratio and Data Freshness in Real-Time Database ModelsSanjay Tanwani, Ashwani K. RamaniImportant applications, like e-commerce, online stock trading, traffic control demand real-time data services. Conventional database perform poor at these applications. A database for real-time data services has to support timing constraints and temporal consistency in addition to supporting characteristics of a conventional database system. In other words, it is desirable to execute transactions within its deadline using updated data reflecting … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards a Scalable File System on Computer Clusters Using DeclusteringVu Anh Nguyen, Samuel Pierre, Dougoukolo KonaréThis study addresses the scalability issues involving file systems as critical components of computer clusters, especially for commercial applications. Given that wide striping is an effective means of achieving scalability as it warrants good load balancing and allows node cooperation, we choose to implement a new data distribution scheme in order to achieve the scalability of computer clusters. We suggest … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of an Input Queuing Packet SwitchAzeddine Bilami, Mustapha Lalam, Mohamed BenmohammedMany Architectures of Internet routers, ATM and Ethernet switches have been proposed and analysed in literature. Theoretically reliable and valid solutions have been developed to achieve high performances, but a lot of them are not feasible in practice for commercial and technological reasons. Few papers develop the implementation and simulation aspects. The objective of this study is the design of … …Journal of Computer Science, Vol. 1, Issue 3 · 19 Sep 2005 · 6,926 accessesView PDFCite
