Research ArticleOpen accessIn the abstractNeural Networks Based Time-Delay Estimation using DCT CoefficientsSamir J. Shaltaf, Ahmad A. MohammadThis study dealt with the problem of estimating constant time delay embedded into a received signal that was noisy, delayed and damped image of a known reference signal. The received signal was filtered, normalized with respect to the peak value it achieved and then transformed by the Discrete Cosine Transform (DCT) into DCT coefficients. Those DCT coefficients that were most … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractProperties of Absolute Stability in the Presence of Time LagsM. De la Sen, J. L. Malaina, A. Gallego, J. C. SotoThis study is concerned with the properties of absolute stability independent of the delays of time-delay systems, possessing non commensurate internal point delays, for any nonlinearity satisfying a Popov’s- type time positivity inequality. That property holds if an associate delay-free system is absolutely stable and the size of the delayed dynamics is sufficiently small. The results are obtained for nonlinearities … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,569 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Traffic Flow and Management at Un-signalized, Signalized and Roundabout Road IntersectionsR. Kakooza, L.S. Luboobi, J.Y.T. MugishaTraffic congestion continues to hinder economic and social development and also has a negative impact on the environment. A simple mathematical model is used to analyze the different types of road intersections in terms of their Performance in relation to managing traffic congestion and to establish the condition for stability of the road intersections after sufficiently longer periods of time … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,611 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsymptotic Hyperstability of Dynamic Systems with Point DelaysM. De la SenIt is proved that a linear time-invariant system with internal point delays is asymptotically hyperstable independent of the delays if an associate delay-free system is asymptotically hyperstable and the delayed dynamics are sufficiently small. …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Performance of Traffic Dependent Outage Rate Cellular SystemHussein M.A. Basi, M. B.R. MurthyThe designers of a mobile cellular system must evaluate the possible configurations of the system components and their characteristics in order to develop a system with greater efficiency. The useful parameters to estimate performances of the system are voice quality, frequency spectrum efficiency and grade of service (GOS). In this study, a scheme proposed to reduce the lost calls and … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,812 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Edible Coatings, Storage Time and Maturity Stage on Overall Quality of Tomato FruitsJorge Esteban de Jesús Dávila-Aviña, José Villa-Rodríguez, Reynaldo Cruz-Valenzuela et al.Problem statement: Tomato (Lycopersicon esculentum Mill.) is one of the most widely consumed fresh vegetables in the world; however, its highly perishable nature limits its postharvest life. Major losses in tomato quality and quantity occur between harvest and consumption. Therefore, the application of new technologies to extend the postharvest life of this commodity is needed. The use of edible coatings … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 14 Mar 2011 · 11,286 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordStability of Non-Neutral and Neutral Dynamic Switched Systems Subject to Internal DelaysM. De la Sen, J. L. Malaina, A. Gallego, J. C. SotoThis study deals with the quadratic stability and linear state-feedback and output-feedback stabilization of switched delayed linear dynamic systems with, in general, a finite number of non commensurate constant internal point delays. The results are obtained based on Lyapunov’s stability analysis via appropriate Krasovsky-Lyapunov’s functionals and the related stability study is performed to obtain both delay independent and delay dependent … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,720 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Simple Scheme for Improved Performance of Fixed Outage Rate Cellular SystemHussein M.Aziz Basi, M. B.R. MurthyThe traffic characteristic of mobile cellular systems is rather distinct from that of a fixed telephone network. However the system planning and design are still carried out with the tools of conventional traffic theory. In the recent days much work is being done in the performance evaluation of mobile or cellular communication systems in order to develop a system with … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,078 accessesView PDFCite
