Research ArticleOpen accessIn the abstractRoughness Effect on an Unsteady Flow in Pipelines by Profilometry and Imaging TechniquesMabrouk Benkhedimallah, Rabah Zegadi, Mohamed BouafiaProblem statement: Currently the aero dynamical calculation in gas pipes is carried out under the assumption of steady state conditions. However real steady in a network is scarcely quasisteady. Approach: The unsteady state is governed by non-linear partial differential equations leading to mathematical difficulties. And there are fore gas pipe dimensions are computed at steady state under extreme conditions. Results: … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 29 Jan 2011 · 8,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Triple Play Services Using Multi Protocol Label Switching TechnologyWaheed Yasin, Hamidah IbrahimProblem statement: Traditional IP networks have many limitations such as routing tables, which can be complex and time consuming. These limitations affect the performance of the network in some applications of triple play services (i.e., voice, video and data) which are characterized as time sensitive applications. Thus, Multi Protocol Label Switching (MPLS) technology has been proposed to speed up the … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractVisualization of Available Power Transfer Capability in a Transmission System Using Morphological TechniquesS. U. Prabha, B. S. Dayasagar, C. VenkataseshaiahA morphological decimation technique has been proposed and implemented to analyze the available power transfer capability in a transmission power network. The method creates a graphical image of the power network with thickness of the lines proportional to their respective rated megavolt ampere (MVA) capacity. Based on ac load flow solution, another image was created to represent the power flow … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,102 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Multi-Agent Technology on Transient Stability Assessment of Iraqi Super Grid NetworkAfaneen A. Abood, Ahmed N. Abdalla, Shant K. AvakianThe aim of this research is improving the Iraqi control center's capabilities for monitoring and controlling the electrical network by adopting the properties of multi-agent technology to enhance power system transient stability. The idea was demonstrated by two agent's strategy, the first agent is a prediction one that will predict power system instability by a transient stability program using the … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,321 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneralized Shortest Path Problem in Uncertain Environment Based on PSOHayder A. Mukhef, Ekhlas M. Farhan, Mohammed R. JassimGeneralized network problems describe situations in which flow can be generated or consumed through arcs. This research considers generalized shortest path problem in stochastic environment in which the changing rate of flow is random. To satisfy the demands of decision makers, three types of models have been formulated to solve the generalized shortest path problem under different decision criteria. The … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 6,749 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatic Synchronous Series Compensator Controller based on Fuzzy Logic Control for Power System StabilizationPrechanon KumkratugProblem statement: Modern power system consists of the complicated network of transmission lines and carries heavy demand. Thus they cause in the stability problem. Approach: Static Synchronous Series Compensator (SSSC) is a power electronic based device that has the capability of controlling the power flow through a line. The series voltage injection model of SSSC is modeled into power flow … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 7 Sep 2011 · 7,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Malaysia's Energy System: Some Preliminary ResultsAhmad Mohd. YusofProblem statement: The current dynamic and fragile world energy environment necessitates the development of new energy model that solely caters to analyze Malaysia’s energy scenarios. Approach: The model is a network flow model that traces the flow of energy carriers from its sources (import and mining) through some conversion and transformation processes for the production of energy products to final … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 13 Aug 2011 · 7,250 accessesView PDFCite
