Research ArticleOpen accessIn the abstractReal Time Hybrid Controller Implementation for Switched Reluctance Motor DriveS. Paramasivam, R. ArumugamThis study presents the real time hybrid controller implementation for a Switched Reluctance motor Drive. The developed hybrid control law consists of Proportional Integral (PI) controller at steady state, PI-type fuzzy logic controller (FLC) at transient state and a simple logic controller between steady and transient states to achieve desired performance at various operating conditions under soft chopping operation. The … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,240 accessesView PDFCite
Research ArticleOpen accessIn the abstractLinks between Dynamic Physical Systems and Operator Theory Issues Concerning Energy Balances and StabilityM. D.L. SenThis study relates the properties of operators with the well- known concepts of positive realness and passivity properties in dynamic systems and their associate transfer functions. Those concepts together with very close related ones are first examined from a physical point of view. Then, they are related to hyper-stability and properties of transfer functions while the hyper-stability theorem is revisited … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrom a Vicious Circle of Anxiety to a Virtuous Circle of Learning: Experience of Teaching Statistics to a Heterogeneous ClienteleMohammad Alauddin, James E. ButlerA considerable body of literature suggests that significant psychological barrier and anxiety characterize the teaching and learning process in statistics. This study investigates the incidence of statistics anxiety, the extent to which it can be overcome and the factors that contribute to the process of overcoming it. Self-study and overall teaching quality, amongst others, significantly contributed to this outcome. This … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware Design of Wireless Physical Token Ring System for Mobile and Cell CommunicationNidal F. Shilbayeh, Mahmoud Z. IskandaraniA wireless network system based on an infrared and Laser scanning Physical Token Ring architecture (W-PTRS) was designed, built and tested successfully. The network provides a different way of utilizing the concept of a token ring network but with a higher efficiency related to the speed of data transfer and the ability to parallel process client-server requests leading to a … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation of the Nature Properties of PlasmaPeter Evans, Frederick Osman, Heinrich HoraThis study presents the characteristics of the plasma and the effect of the laser beam to best suit the plasma model behavior. Special attention is paid to the “Genuine” Two Fluid Model and the ponder-motive and transient forces. These models are translated into a numerical study of the parameters, such as the electric field density and temperature distributions once electromagnetic … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,566 accessesView PDFCite
Research ArticleOpen accessIn the abstractMalaysian Service Sectors Adopt FEDI to Boost Exports and ImportsSaravanan MuthaiyahFinancial Electronic Data Interchange (FEDI) refers to making cash payments electronically rather than utilizing any form of traditional payment methods such as physical checks. The merger of two unique systems namely Electronic Fund Transfer (EFT) and Electronic Data Interchange (EDI) has brought about this new technology. The primary objective of this study is to ascertain how FEDI is currently being … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,757 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Energy Loss in the Steam Valves and its EffectsGalip Temir, Durriye BilgeIn this study, the effects of thermal losses in steam valves for flow have been analyzed. In a set of experiment built to achieve this, pressure and condensate values have been calculated in different temperatures for insulated and non-insulated cases in three different nominal diameter steam valves. The amount of energy lost from the valve surface in the natural convection … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,202 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Causal Relationship between Inflation and Productivity: An Empirical Approach for RomaniaNikolaos DritsakisThis study attempts to analyze the relationship between the productivity and the inflation of a transition country of the European Union as Romania. For this purpose we use quarterly data since 1990: IV in 2003: I and the causality analysis, which is based on an error correction model. The results of the empirical analysis showed that there is a causal … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuppression of Instabilities and Stochastic Pulsation at Laser-Plasma Interaction by Beam SmoothingFrederick Osman, Heinrich HoraThe key problem of direct drive laser fusion is the appearance of parametric instabilities, stochastic pulsation, self-focusing (filamentation) and other anomalies. During the long years studies, the empirical and intuitively developed methods for smoothing of the laser beam were rather successful but a transparent understanding of the physics has still to be found. The first theory how the instabilities are … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,796 accessesView PDFCite
