Research ArticleOpen accessIn the keywordsA NOVEL APPROACH BASED ON GENETIC FUZZY CLUSTERING AND ADAPTIVE NEURAL NETWORKS FOR SALES FORECASTINGAttariuas Hichama, Bouhorma Mohameda, El Fallahi AbdellahbThis article proposes a new hybrid sales forecasting system based on genetic fuzzy clustering and Back-Propagation (BP) Neural Networks with adaptive learning rate (GFCBPN).The proposed architecture consists of three stages: (1) utilizing Winter’s Exponential Smoothing method and Fuzzy C-Means clustering, all normalized data records will be categorized into k clusters; (2) using an adapted Genetic Fuzzy System (MCGFS), the fuzzy … …Journal of Computer Science, Vol. 9, Issue 8 · 2 Jul 2013 · 6,675 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTwigX-Guide: Twig Query Pattern Matching for XML TreesSu-Cheng Haw, Chien-Sing LeeThe growing importance of XML and the lack of efficient solutions for managing and querying XML data have led to the development of hybrid systems. We present a hybrid system, TwigX-Guide; an extension of the well-known DataGuide index and region encoding labeling to support twig query processing. With TwigX-Guide, a complex query can be decomposed into a set of path … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,082 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimal Decentralized Load Frequency Control Using HPSO Algorithms in Deregulated Power SystemsSeyed Abbas Taher, Reza Hematti, Ali Abdolalipour, Seyed Hadi TabeiLoad Frequency Control (LFC) is one the most important issues in electrical power system design/operation and is becoming much more significant recently with increasing size, changing structure and complexity in interconnected power systems. In practice LFC systems use simple Proportional-Integral (PI) or Integral (I) controllers. However, since the PI or I control parameters are usually tuned based on classical or … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,393 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Multi-Objective HPSO Algorithm Approach for Optimally Location of UPFC in Deregulated Power SystemsSeyed Abbas Taher, Seyed Mohammad Hadi TabeiThis paper presents the application of hybrid particle swarm optimization technique to find optimal location of unified power flow controller to achieve optimal power flow. Objective function in the OPF, that is to be minimized, are the overall cost functions, which include the total active and reactive production cost function of the generators and installation cost of UPFCs. The OPF … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,979 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe NifX Protein is Involved in the Final Stages of FeMo-cofactor Transport to the MoFe ProteinSurobhi Lahiri, Byron Cole, Lakshmi Pulakat, Nara GaviniThe nitrogenase enzyme catalyzes the reduction of dinitrogen to ammonia and is composed of the Fe and MoFe proteins. The iron molybdenum cofactor (FeMo-co) of the MoFe protein is the site of active substrate reduction. The NifX protein has also been suggested to have a role in the FeMo-co synthesis, although its exact role is still open to investigation. We … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 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 · 7,168 accessesView PDFCite
