Research ArticleOpen accessAll words, across the recordOn Regression Modeling of Human Immunodeficiency Virus PatientsHadeel Salim AL-KutubiProblem statement: The main propose of this study was to evaluate the HIV patients for the period 1990-2008 depend on three variables age, gender and ethnicity. Approach: The data was analyzed using regression and correlation methods to get the mathematical model that explain the relationship and the effect between the age, gender and ethnicity. SSPS program V. 17.0 was used … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 6,413 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordImpedance Analysis of Heat Treated Polyethylene Oxide Polymeric Material for a Neural Storage ApplicationMahmoud Z. IskandaraniProblem statement: From the early days of, researchers have developed electronic models of neurons designed to emulate neural behavior with electrical signals that mimic in some ways the measured potentials of biological neurons. Researchers interested in fabricating artificial neurons have long sought a simple and techniques to produce devices that efficiently store synaptic weights, which is behind holding a particular … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,085 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordModeling of Transient Heat Flux in Spark Ignition Engine During Combustion and Comparisons with ExperimentT. F. Yusaf, Sye Hoe, Fong et al.A quasi-one dimensional engine cycle simulation program was developed to predict the transient heat flux during combustion in a spark ignition engine. A two-zone heat release model was utilized to model the combustion process inside the combustion chamber. The fuel, air and burned gas properties throughout the engine cycle were calculated using variable specific heats. The transient heat flux inside … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,173 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordModeling 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 PDF Cite

Research ArticleOpen accessAll words, across the recordDynamical Properties Analysis of Frictional Winding Mechanism with Bobbin Elastic SupportMohammed A. Alnawafleh, Faisal M. Al-GhathianA mathematical model of the Frictional Winding Mechanism (FWM) with bobbin elastic supports for a search of optimal structural and physical parameters for developing new and updating existing FWMs has been carried out. The model was derived from bobbin equipped with pendulum suspension for forming cylinder shaped packages. In the derivation method it was considered that the model corresponds the … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,879 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordModeling of Particle Separation in Bends of Rectangular Cross-sectionBingtao ZhaoA new theoretical model for predicting particle separation efficiency in bends is developed based on the investigation of flow pattern, the critical particle size separation theory and the boundary layer separation theory. The radial particle concentration gradient, instead of the usually assumed uniform radial particle concentration within the bends, is considered in this mathematical model. The local particle concentration and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,852 accessesView PDF Cite
