Research ArticleOpen accessIn the keywordsImproved AIMD- A Mathematical StudyV. S.P. Srivastav, M. K. Gupta, Sachin Kumar, Kadambri AgarwalOne of the crucial elements in the Internet is the ability to adequately control Congestion. AIMD (Additive Increase Multiplicative Decrease) is the best algorithm among the set of liner algorithms because it reflects good efficiency as well as good fairness. Our Control model is based on original approach of AIMD. In this paper we introduce improved version of AIMD. We … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMinimization of Load Oscillations in Travelling Mechanisms of CranesKamal KhandakjiThe paper presents an analysis of suspended load (cargo) oscillations in traveling mechanisms of cranes. A special control algorithm has been developed in order to get minimum cargo oscillations in minimum transient time. Mathematical model simulating the effect of the suggested control algorithm on cargo oscillations has been developed. Two power electronic circuits applicable for AC drives with three-phase induction … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,672 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign of Field Programmable Gate Array Based Emulators for Motor Control ApplicationsAhmed Ben Achballah, Slim Ben Othman, Slim Ben SaoudProblem statement: Field Programmable Gate Array (FPGA) circuits play a significant role in major recent embedded process control designs. However, exploiting these platforms requires deep hardware conception skills and remains an important time consuming stage in a design flow. High Level Synthesis technique avoids this bottleneck and increases design productivity as witnessed by industry specialists. Approach: This study proposes to … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 12 Jun 2012 · 8,723 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimal Arrangement of Energy-Dissipating Members for Seismic Retrofitting of Truss StructuresToru Takeuchi, Yusuke Kinouchi, Ryota Matsui, Toshiyuki OgawaAlthough passive response control design is a popular method, an arrangement methodology for energy-dissipating devices in spatial structures has not been established yet. In this study, optimization techniques are applied to arrangements of energy-dissipating devices in truss tower structures. First, a response prediction rule using the response spectrum and the equivalent linearization method is proposed. Then, a genetic algorithm is … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Jul 2015 · 7,619 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA REVIEW OF INTELLIGENT CONTROL SYSTEMS APPLIED TO THE INVERTED-PENDULUM PROBLEMPedro Ponce, Arturo Molina, Eugenio AlvarezThis study shows the latest advances in the application of intelligent control to the inverted-pendulum problem. A complete review regarding intelligent control design is presented in this study in order to show the most important artificial intelligence methods used for controlling an Inverted-Pendulum. Also this study proposed the use of a neural-fuzzy-with-genetic-algorithms controller for the inverted pendulum problem which gives … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 2 · 7 Apr 2014 · 8,379 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStochastic Estimator-Based Wireless Traffic Control SchemesFrancis Joseph Ogwu, Mohammad Talib, Ganiyu Adesola AderounmuRecent works on Available Bit Rate (ABR) traffic control have generated efficient control schemes for ABR traffic on Asynchronous Transfer Mode (ATM) network. This study examines the improved performance envisaged if these control schemes adjust dynamically to the varying ABR bandwidth capacity in a stochastic manner instead of conventional deterministic approach .The performance difference between setting explicit rate deterministically for … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 7,099 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimizing Inventory Using Genetic Algorithm for Efficient Supply Chain ManagementP. Radhakrishnan, W. M. Prasad, M. R. GopalanProblem statement: Today, inventory management is considered to be an important field in Supply chain management. Once the efficient and effective management of inventory is carried out throughout the supply chain, service provided to the customer ultimately gets enhanced. Hence, to ensure minimal cost for the supply chain, the determination of the level of inventory to be held at various … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 8,362 accessesView PDFCite
