Research ArticleOpen accessIn the abstractEMBEDDED CONTROLLED MULTI LEVEL VOLTAGE SOURCE INVERTER BASED DISTRIBUTION STATICS SYNCHRONOUS COMPENSATORP. Venkata Kishore, S. Rama ReddyThis study deals with the D-STATCOM used as a shunt connected compensator for the voltage support. The D-STATCOM has a faster response as compared with the conventional compensators such as the synchronous condenser and the SVC. The D-STATCOM can provide voltage support and improve power quality. The D-STATCOM supplies reactive power to the load to improve the voltage stability of … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 5 May 2014 · 6,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Exhausting Exercise Induced Fatigue on the Double-Leg Balance of Elite Male AthletesKhodadad Letafatkar, Mohammad Hossein Alizadeh, Mohammad Reza KordiProblem statement: Fatigue is a complex phenomenon that can be described as a time-dependent exercise-induced reduction in the maximal force generating capacity of a muscle. The aim of the present study was to examine the effect of exhausting exercise induced fatigue on the double-leg balance of elite male athletes. Approach: This study included 30 apparently healthy young adults (handball and … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Logic Controller Based Three-phase Shunt Active Filter for Line Harmonics ReductionC. Sharmeela, M. R. Mohan, G. Uma, J. BaskaranHarmonic distortion is a form of electrical noise. It is a superposition of signals, which are of multiples of fundamental frequency. Proliferation of large power electronic systems results in increased harmonic distortion. Harmonic distortion results in reduction of power quality and system stability. This paper presents fuzzy control applicable for active power filter for three-phase systems, which are comprised of … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 7,107 accessesView PDFCite
Research ArticleOpen accessIn the abstractDamage Pattern and Nesting Characteristic of Coptotermes curvignathus (Isoptera: Rhinotermitidae) in Oil Palm on PeatWei-Hong Lau, Choon-Fah J. Bong, Seow-Phan ChanThe oil palm industry of Malaysia has expanded into peat area in Sarawak. Problem statement: The subterranean termite Coptotermes curvignathus was a serious pest of oil palm on peat. Control of this termite has resorted to heavy usage of chemicals which was deemed uneconomical and hostile to the environment. Baiting system has inconsistent success due to the limited knowledge of … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,657 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordKalman Filtering for Stocks Price Prediction and ControlJimbo Henri Claver, Mbiazi Dave, Shu Felix CheStocks price analysis has been a critical area of research as the stock market is a very fluctuating market. Stocks price is affected by demand and supply dynamics making it difficult to forecast the price of a stock at a particular instant. The entire idea of predicting stocks price is to gain significant profits but predicting how the stock market … …Journal of Computer Science, Vol. 19, Issue 6 · 20 May 2023 · 6,367 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUniversal Singular Optimal Control: Affine SystemsAndres Gabriel Garcia, Juan Andrés Roteta LannesIn this study, the problem of finding an optimal controller for nonlinear systems with one input and a reference tracking signal is approached. With the problem's formulation, any desired signal can be tracked instantly with a closed-loop controller without the need for integral terms. Presentation lies at the heart of optimal control. This study, however, does not consider the integral … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 14 Dec 2022 · 5,452 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordController Based Observer in Switched System with Norm Bounded UncertaintyMongi Besbes, Elyes MaherziProblem statement: This study discusses the robust stabilization of norm bounded discrete switched systems. Approach: The proposed method is using the second Lyapunov approach and the poly-quadratic function concept. The stabilization conditions are written through linear matrix inequality relations. The control law is based on a static output feedback with the use of a switched observer. The synthesis conditions of … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 11 May 2012 · 6,904 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordFormulation and Evaluation of a Novel Needle-Free Hepatitis B Surface Antigen Delivery SystemC. D. Licy, K. Premalatha, Annie Shirwaikar, Arun ShirwaikarProblem statement: Hepatitis B is a major public health problem, killing 1-2 million people annually, despite the introduction of an effective vaccine in 1982. Approximately 400 million persons worldwide have chronic hepatitis B. This is due to problems associated with vaccine delivery, stability and cost. Hence the present challenge in Vaccinology is to develop safer, cheaper and easy-to-deliver forms of … …Current Research in Medicine, Vol. 1, Issue 2 · 30 Oct 2010 · 6,819 accessesView PDFCite
