Research ArticleOpen accessIn the abstractPiecewise Sliding Mode Decoupling Fault Tolerant Control SystemRafi Youssef, Hui PengProblem statement: Proposed method in the present study could deal with fault tolerant control system by using the so called decentralized control theory with decoupling fashion sliding mode control, dealing with subsystems instead of whole system and to the knowledge of the author there is no known computational algorithm for decentralized case, Approach: In this study we present a decoupling … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,388 accessesView PDFCite
Research ArticleOpen accessIn the abstractReconfigurable Elliptic Curve Crypto-Hardware Over the Galois Field GF(2163)Mohamed Abdelkader Bencherif, Hamid Bessalah, Abderrezak GuessoumProblem statement: In the last decade, many hardware designs of elliptic curves cryptography have been developed, aiming to accelerate the scalar multiplication process, mainly those based on the Field Programmable Gate Arrays (FPGA), the major issue concerned the ability of embedding this strategic and strong algorithm in a very few hardware. That is, finding an optimal solution to the one … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,346 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Decentralized Control of Unified Power Flow ControllerHossein Shayeghi, Ali AbdolalipourA new approach based on structured singular value is proposed for the robust decentralized Unified Power Flow Controller (UPFC) design. To achieve decentralization, using the schauder fixed point theorem the synthesis and analysis of Multi-Input Multi-output (MIMO) control system is translated into set of equivalent Multi-Input Single-Output (MISO) control system. Power systems such as the other industrial plants contain different … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,151 accessesView PDFCite
Research ArticleOpen accessIn the abstractProviding Reliability in Replicated Middleware ApplicationsR. Saravanan, N. RamarajProblem statement: Data inconsistency is raised in actively replicated environment due to non-determinism in the applications that defeats the purpose of replication as a fault-tolerance strategy. Approach: We proposed an efficient framework RTC which ensured determinism among the replicas in fault tolerance middleware applications. This method exploits the technique of statically analyzing the application source code of client and identifies … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 8,696 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Econometric Model for Water Sector in JordanMohammed Issa ShahateetProblem statement: This study argued that there is an economic approach to reduce water problems faced by Jordan. The study took into consideration the increasing population size, the declining rainfall, a deepening shortage of supply and increasing demand for water, the production of agricultural and industrial sectors, price of unit exports, and lack of financial resources. Approach: The framework for … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractInformation Protection in Academic Campuses: A Scalable FrameworkD. S. Bhilare, A. K. Ramani, S. TanwaniProblem statement: Most institutions recognize the critical role that information security risk management plays in supporting their missions and objectives. Often, institutions do not pay enough attention towards assessing effectiveness of existing security measures. They are also unable to respond to new security threats in reasonable time. Furthermore, new laws are also forcing institutions to manage security risk more closely … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,872 accessesView PDFCite
