Research ArticleOpen accessIn the abstractMathematical Analysis of the Non Linear Epidemic ModelLaid Chahrazed-Rahmani Fouad LazharClassical epidemic models assume that the size of the total population is constant. More recent models consider a population size variable to take into account a longer period with death and disease causing reduced reproductive. The model contains a disease-free equilibrium and one or multiple equilibria are endemic. The stability of a disease-free status equilibrium and the existence of other … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 19 Jun 2012 · 7,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 2-12 GHz Low Noise Amplifier Design for Ultra Wide Band ApplicationsV. Vaithianathan, J. Raja, R. SrinivasanProblem statement: The Low Noise Amplifier (LNA) is a core block of an Ultra Wide Band (UWB) receiver since it amplifies a very weak signal received at the antenna to acceptable levels while introducing less self-generated noise and distortions. The LNA design poses a unique challenge as it requires simultaneous optimization of various performance parameters like power gain, input matching, … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 9 Jun 2012 · 7,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Control of a Greenhouse by Variation in Ventilation Rate using a Fuzzy Parallel Distributed Compensation Controller with an RST Regulator in Each RuleElyes Feki, Amine Chouchaine, Abdelkader MamiProblem statement: The greenhouse has uncontrollable inputs that affect its climate, which arises the difficulty to regulate its inside temperature. The solution can be found using a multi-system approach like the Takagi-Sugeno System from which a design of a Parallel Distributed Compensation (PDC) controller is performed. However, a stability problem arises and was negotiatesd in general based on a Lyapunov … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 27 Apr 2012 · 7,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Flow Systems and Their Response to Climate Change: A Need for a Water-System View ApproachJoel J. Carrillo-Rivera, Antonio CardonaProblem statement: The interest in early hydrogeological studies was the aquifer unit, as it is the physical media that stores and permits groundwater transfers from the recharge zone to the discharge zone, making groundwater available to boreholes for water extraction. Approach: Recently, the aquifer concept has been complemented by the groundwater flow system theory, where groundwater may be defined by … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 7 Apr 2012 · 8,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Theories of Complexity and Chaos to Economic MisgovernancePartha Gangopadhyay, Nasser Elkanj, Mustafa A. RahmanProblem statement: In this study we develop a comprehensive model involving local taxes, intergovernmental transfers and bureaucratic corruption to characterize a fiscal equilibrium in order to explain the provision of local (public) expenditure in developing nations. The main goal of the research is to explain economic misgovernance as an equilibrium phenomenon, which is therefore expected to persist over time despite … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 27 Jul 2011 · 7,375 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Molam in Solving Social ProblemsSitthisak ChampadaengProblem statement: Mo-lam is the most popular Isan Local Song. Its rhythm and message influenced people’s feeling and thought. The objectives of this research were to study: (1) the moving force in using the media of Mo-lam for solving social problem, (2) the role of Mo-lam and social problem solving and (3) the effect of campaign with the sharing in … …Journal of Social Sciences, Vol. 6, Issue 3 · 30 Sep 2010 · 7,973 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability Analysis of a Class of Three-Neuron Delayed Cellular Neural NetworkPoulami Das Gupta, N. C. Majee, A. B. RoyProblem statement: In this study linear stability of a class of three neuron cellular network with transmission delay had been studied. Approach: The model for the problem was first presented. The problem is then formulated analytically and numerical simulations pertaining to the model are carried out. Results: A necessary and sufficient condition for asymptotic stability of trivial steady state in … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,598 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetecting Malaysian Housing BubblesYip Chee Yin, Wong Woei Chyuan, Woo Kok HoongThis paper examines whether Malaysia is facing an impending housing bubble by using a graphical analysis, logical deduction and two statistical tests. Our research results are robust and supported by a three prone approach: Logical deduction working on the historical price trend based on most recent research findings on bubble; testing the stability of the price cycle and a statistical … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 20 Mar 2016 · 8,332 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid of Fuzzy Clustering Neural Network Over NSL Dataset for Intrusion Detection SystemDahlia Asyiqin Ahmad Zainaddin, Zurina Mohd HanapiIntrusion Detection System (IDS) is one of the component that take part in the system defence, to identify abnormal activities happening in the computer system. Nowadays, IDS facing composite demands to defeat modern attack activities from damaging the computer systems. Anomaly-Based IDS examines ongoing traffic, activity, transactions and behavior in order to identify intrusions by detecting anomalies. These technique identifies … …Journal of Computer Science, Vol. 9, Issue 3 · 4 May 2013 · 6,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractPublicly Funded Education and Human Capital in the Presence of a Convex-Concave Education FunctionBinh Tran-Nam, Công Nghê TruongThis study investigates an aggregative optimal growth model in which short-lived individuals obtain their labour skill through education. The process of human capital formation is described by an increasing, convex-concave education function relating the success rate to the educational expenditure per student. The cost of education is publicly funded by an income tax imposed on adult workers. Despite the apparent … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 7 Dec 2005 · 7,869 accessesView PDFCite
