Research ArticleOpen accessIn the abstractRule Extraction from Radial Basis Functional Neural Networks by Using Particle Swarm OptimizationM. R. Senapati, I. Vijaya, P. K. DashRadial basis functional neural networks (RBFNN) provide an outstanding possibility for generating rules for solving pattern classification problems. One of the most important factors in RBFNN is finding out the center and spread. This paper examines rules extracted from RBF networks trained by Particle swarm Optimization (PSO). The selection of the RBFNN centers, spreads and the network weights can be … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomedicine and Informatics Model of Alzheimer's DiseaseKang Cheng, Chang-Hua ZouIn a perspective of biomedicine and informatics, the mechanism of Alzheimer's, senile amnesia, or other aging-associated and cognitive impairment related diseases involve four important informative processing procedures: propagation, consolidation, retrieval and cognition, In this study, we systematically model the four procedures based on published experimental data. When modeling the propagation, we develop an equivalent circuit of biological membrane to describe … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 28 May 2007 · 6,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of AODV in Wireless Ad Hoc NetworksZeyad M. Alfawaer, GuiWei Hua, Nidal A. HamdehAODV is a mature and widely accepted routing protocol for Mobile Ad hoc Networks (MANET), it has low processing and memory overhead and low network utilization, and works well even in high mobility situation. We modified AODV to use these dominating sets, resulting in the AODV-DS protocol. Our contribution in addressing the fragility of a minimum connected dominating set in … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation on the Behavior of Rigid Polyvinylchloride Pipes Subjected to Uniaxial Compression LoadsAbdullah Ali Nasser Alhamati, Abdul Halim Ghazali, Jamalodin Norzaie et al.The objective of this research was to investigate the capability of rigid Polyvinylchloride (PVC-U) pipes to sustain axial loads. The behavior of PVC-U pipes specimens subjected to short-term uniaxial compression loads was experimentally investigated. Results of the load-displacement tests on pipes of different wall thickness, diameter and specimen heights were recorded. The experimental test results show that the PVC-U pipes … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 6,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Software Quality Model for Evaluating COTS ComponentsAdnan Rawashdeh, Bassem MatalkahStudies show that COTS-based (Commercial off the shelf) systems that are being built recently are exceeding 40% of the total developed software systems. Therefore, a model that ensures quality characteristics of such systems becomes a necessity. Among the most critical processes in COTS-based systems are the evaluation and selection of the COTS components. There are several existing quality models used … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 11,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Fast Methods for Fitting Some One-parameter Spatial ModelsR. J. MartinIt is common in geographic modelling to use a one-parameter spatial model to specify the inverse covariance matrix in terms of I-βW, for some known matrix W. Exact Gaussian maximum likelihood estimation of β requires evaluation of the determinant of the covariance matrix. For large data sets, this evaluation of the determinant can be slow and good approximations can be … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractParsimonious Var Models For Air Pollution Dynamic AnalysisFontanella lara, Granturco mariagraziaWe discuss a framework to obtain temporal predictions for an evolving spatial field regularly sampled in time at arbitrary spatial locations. Difficulties caused by large data sets and the modelling of complicated spatio-temporal interactions limit the effectiveness of traditional space-time statistical models. In this study, we propose the use of a flexible approach to deal with large and small time-scale … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,183 accessesView PDFCite

Research ArticleOpen accessIn the abstractThe Possibility of Cyclical Behavior in a Class of Dynamic ModelsAnjan MukherjiThe study investigates conditions under which endogenous cyclic behavior may be observed within the context of Predator-Prey (Lotka-Volterra) Models. The analysis also establishes conditions under which such behavior is non-existent and hence establishes conditions for global convergence to the interior equilibrium, whenever it exists. The results are then applied to two diverse sets of economic exercises and shows how the … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 9 Dec 2005 · 7,602 accessesView PDFCite
