Research ArticleOpen accessAll words, across the recordA New Engineering Method for Fuzzy Reliability Analysis of Surge Control in Centrifugal CompressorAhmed Hafaifa, Ferhat Laaouad, Moulod GuemanaProblem statement: The surge phenomenon in the centrifugal compressor, the non-linearities and uncertainties of the compression system make it impossible to use a conventional controller over a wide range of operation. Approach: A new dual fuzzy controller for nonlinear model of compression system was proposed in this study. This fuzzy controller was designed that consisted of active surge control and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,224 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Scheduling Algorithm Based on Petri Nets and Simulated AnnealingRachida Hadiby Ghoul, Abdelhamid Benjelloul, Sihem Kechida, Hicham TebbikhThis study aims at presenting a hybrid Flexible Manufacturing System "HFMS" short-term scheduling problem. Based on the art state of general scheduling algorithms, we present the meta-heuristic, we have decided to apply for a given example of HFMS. That was the study of Simulated Annealing Algorithm SA. The HFMS model based on hierarchical Petri nets, was used to represent static … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,164 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAccessing Applications from Multiple File Servers in a Computer NetworkJ. S.J. Daka, J. S. IsaacThis study proposes a technique of accessing applications from multiple file servers in a computer network that caters for a large user community. The technique is a step towards creating a computer network system that is simple to implement, scalable, easy to manage, transparent to the user and suitable for a university-type environment. The proposed technique has some features of … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,765 accessesView PDFCite
