Research ArticleOpen accessIn the abstractStability 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 · 6,723 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalyzing the Electricity Consumption Using Experimental Design TechniqueS. F. Ghaderi, M. A. Azadeh, Sh. BamdadExperimental design technique is a powerful tool that is used in uncertainty cases, when a great amount of data is available. In this paper, the effects of different factors on the determination of electricity consumption are analyzed. This analysis is based on experimental design technique. The implementation of the proposed technique is shown applying electricity consumption in Iran. …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractHarmonics Study and Comparison of Z-source Inverter with Traditional InvertersB. Justus Rabi, R. ArumugamThis paper presents an Impedance Source Inverter for A.C electrical drives. The impedance source inverter employs a unique impedance network cable with inverter main circuit and rectifier. By controlling the shoot-through duty cycle, the z-source inverter system using MOSFETS provide ride-through capability during voltage sags, reduces line harmonics, improves power factor and high reliability, and extends output voltage range. Analysis, … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Absorption Coefficients and Thermal Diffusivity of Modulated Doped GaAlAs/GaAs Heterostructure by Photothermal Deflection SpectroscopyS. Aloulou, M. Fathallah, M. Oueslati, A. SfaxiWe report in this study theoretical and experimental studies of photothermal deflection spectroscopy (PDS) for planar doped heterostructures AlGaAs/GaAs. The PDS spectra at T=300K are recorded by varying the wavelength of the excited radiation for different modulation frequencies. They show two different regions related to the fundamental electronic transitions from GaAs and Si doped AlGaAs. The DX levels have been … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractBalancing Treatment and Prevention: The Case of HIV/AIDSJoseph Y.T. MugishaA mathematical model is formulated to study the effect of treatment of HIV/AIDS patients on the spread of the epidemic in a two-age group’s population. The model assumes the sexual transmission mode. A proportion δ, of the adult HIV/AIDS infects is assumed to be receiving treatment. The analysis of the model shows that treatment that is not accompanied by a … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Model Mathematical Models for the Dynamics of Tuberculosis in Density-dependent Populations: The Case of Internally Displaced Peoples' Camps (IDPCs) in UgandaA. Ssematimba, J. Y.T. Mugisha, L.S. LuboobiMathematical models are formulated to establish the conditions (restrictions) on the size of the area occupied required minimizing and thereafter eradicating tuberculosis. Both numerical and qualitative analyses of the model are done and the effect of variation in the area size and recruitment rate on the different epidemiological groups is investigated. The results of the analysis show that there exists … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractHemisphere Sizing from Linear Intercept MeasurementWilfried GilleThe stereological problem of unfolding the hemisphere radius distribution from the chord length distribution is analyzed. Let a stationary isotropic process of hemispheres be given. The hemispheres have random diameters and are isotropically uniformly randomly orientated in space. A straight line probe yields a process of intercepts. The inverse problem of re-obtaining the size distribution of the hemispheres in terms … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,149 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 · 6,618 accessesView PDFCite
Research ArticleOpen accessIn the abstractMusic Information Retrieval Schemes in Peer-to-Peer EnvironmentsChaokun Wang, Jianzhong Li, Shengfei ShiPeer-to-peer systems are useful tools for music applications. Existing peer-to-peer systems support the storing and sharing of music data, however they cannot effectively and efficiently support the content-based information retrieval and the cooperation of musicians. This study focuses on the methods of content-based music information retrieval in peer-to-peer environments. Four music information retrieval schemes are evaluated in detail on communication … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Flow in Agriculture: BangladeshM. S. Alam, M. R. Alam, K. K. IslamIn this paper, a qualitative energy flow analysis in Bangladesh agriculture has been made for a period from 1980-81 to 2000-01 to evaluate the impact of energy input to produce output. Human and animal muscle power and machinery energy for tillage operation, electricity and diesel energy for irrigation, fertilizer and pesticides energy for growth and protection are taken into account. … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 11,592 accessesView PDFCite
