Research ArticleOpen accessIn the abstractTransient Response of a Novel Displacement Transducer for Magnetic Levitation SystemMrunal Deshpande, Badrilal MathurProblem statement: In magnetic levitation system, position sensors are used to obtain a voltage proportional to the position of the suspended object. This is an essential feedback signal for stabilizing the system. These sensors make the system clumsy and prone to failures. To eliminate any physical attachment on the levitated object for the purpose of measuring its displacement, a novel … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 5 Oct 2011 · 7,240 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersistence of Traditional Retailing in an Island TownS. Selvadurai, R. Moorthy, N. Lyndon, A. C. ErProblem statement: The convergence of modern retail formats in the developing world is resisted by the persistence of traditional retail formats. The issue of lower-circuit and middle-circuit in traditional retail trade in the modernizing urban arena has raise debates about its co-existence in different cultural and geographical settings. The aim of this study is to examine the persisting organizational features … …American Journal of Economics and Business Administration, Vol. 3, Issue 3 · 15 Sep 2011 · 7,360 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Novel Artificial Neural Network Based Stock Market Forecasting System on Field-Programmable Gate ArraysMd. Syedul Amin, Md. Mamun, Fazida Hanim Hashim et al.Problem statement: Multiagent system is very proficient and has rules well-suited for financial forecast with its neural network. In financial forecasting, the approach for rules extractions is less pertinent and involves algorithms which are complex. The unsupervised network method lacks in comprehensibility and leads to ambiguity. Approach: The application of neural network technology to real-time processing of financial market analysis … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 12 Sep 2011 · 7,634 accessesView PDFCite
