Research ArticleOpen accessIn the author namesA Mobile Robot Path Planning Using Genetic Algorithm in Static EnvironmentIsmail AL-Taharwa, Alaa Sheta, Mohammed Al-WeshahIn this study we present our initial idea for using genetic algorithms to help a controllable mobile robot to find an optimal path between a starting and ending point in a grid environment. The mobile robot has to find the optimal path which reduces the number of steps to be taken between the starting point and the target ending point. … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 20,314 accessesView PDFCite
Research ArticleOpen accessIn the author namesDecentralized Controller Design for Static Synchronous Compensator Using Robust Quantitative Feedback Theory MethodSeyed Abbas Taher, Reza Hematti, Ali Abdolalipour, Majid NematiThe Static Synchronous Compensator (STATCOM) provides shunt compensation in similar way to the Static VAR Compensator (SVC) but utilizes a voltage source converter rather than capacitors and reactor. In practice systems use simple Proportional-Integral (PI) controllers for control of STATCOM. However, since the PI control parameters were usually tuned based on classical or trial-and-error approaches, they were incapable of obtaining … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,461 accessesView PDFCite
Research ArticleOpen accessIn the author namesComparison of Different Control Strategies in GA-Based Optimized UPFC Controller in Electric Power SystemsSeyed Abbas Taher, Reza Hematti, Majid NematiThis study presents a study of the application of a Unified Power Flow Controller (UPFC) to control power transmission, generator terminals voltage and better damping of Low Frequency Oscillation (LFO) in Single-Machine Infinite-Bus (SMIB) power system. The UPFC integrates properties of both shunt and series compensations and can effectively alter power system parameters in a way that increases power transfer … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,606 accessesView PDFCite
Research ArticleOpen accessIn the author namesDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the author namesTransmission Congestion Management by Determining Optimal Location of FACTS Devices in Deregulated Power SystemsSeyed Abbas Taher, Hadi BesharatIn a deregulated electricity market, it may always not be possible to dispatch all of the contracted power transactions due to congestion of the transmission corridors. The ongoing power system restructuring requires an opening of unused potentials of transmission system due to environmental, right-of-way and cost problems which are major hurdles for power transmission network expansion. Flexible ac transmission systems … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,507 accessesView PDFCite
Research ArticleOpen accessIn the author namesSemantics of Lazy Evaluation using the Two-Level GrammarMahmoud A. AbouGhaly, Sameh S. Daoud, Azza A. Taha, Salwa M. AlyWe have formalized the semantics of lazy evaluation for the lambda calculus using the two-level grammar formalism. The resulting semantics enjoys several properties, e.g., there is a sharing in the recursive computation, there is no α conversion, the heap is automatically reclaimed, an attempt to evaluate an argument is done at most once and there is a sharing in the … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,759 accessesView PDFCite
Research ArticleOpen accessIn the author namesInduction of the Chemokines CCL3α, CCL3α and CCL5 in Atherosclerotic PatientsAlyaa Mousa, Amani Al-Zaki, Safa Taha, Moiz BakhietChemokines recruit immune cells to inflammatory sites and promote the process of inflammation. The role of these mediators in the disease process in atherosclerosis is not fully studied. The spontaneous mRNA expression and intracellular protein production of the potential inflammatory chemokines CCL3α and CCL3β (macrophage- inflammatory protein-1α and β; CCR3α/β ligand) and CCL5 (regulated upon activation, normal T cell expressed … …American Journal of Immunology, Vol. 3, Issue 2 · 31 Dec 2007 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the author namesTheoretical and Simulation Approaches for Studying Compensation Strategies of Nonlinear Effects Digital Lightwave Links Using DWDM TechnologyJ. Bel Hadj TaharNowadays, techniques for education are based on the combination of theoretical formulas, experimental measurement and simulation approaches. Theoretical analysis, experimental and simulation approaches based educations allow developing simple and non expensive tools for the aim of studying complex problems in optical network communication. Theoretical formulas, used to describe the non linear effects on digital lightwave links, may by simplified with … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,706 accessesView PDFCite
Research ArticleOpen accessIn the author namesIntegrating Software Architecture Concepts into the MDA Platform with UML ProfileAdel Alti, Tahar Khammaci, Adel SmedaArchitecture Description Languages (ADLs) provide an abstract representation of software systems. Achieving a concrete mapping of such representation into the implementation is one of the principal aspects of MDA (Model Driven Architecture). Integration of ADLs within MDA confers to the MDA platform a higher level of abstraction and a degree of reuse of ADLs. Indeed they have significantly different platform … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,605 accessesView PDFCite
Research ArticleOpen accessIn the author namesAdaptive Control of Networked Systems in the Presence of Bounded DisturbancesA. H. Tahoun, Fang Hua-JingThe insertion of data network in the feedback adaptive control loops makes the analysis and design of networked control systems more complex than traditional control systems. This paper addresses the adaptive stabilization problem of linear time-invariant networked control systems when the measurements of the plant states are corrupted by bounded disturbances. The case of state feedback is treated in which … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,542 accessesView PDFCite
