Research ArticleOpen accessEvery word in the titleA Multi-Dimensional Model of Violent BehaviorManuel Martinez-PonsProblem statement: A model of violence (Multidimensional Model of Violent Behavior; MMVB) was tested. Approach: 416 university students were surveyed to ascertain the difficulty they experience in coping with different forms of violence, violence forms they are prone to exhibit and their levels of psychopathology. Results: Factor analysis disclosed evidence of the MMVB’s construct validity; and correlational analysis shed light … …Journal of Social Sciences, Vol. 7, Issue 2 · 9 Mar 2011 · 7,875 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSplit-Quaternionic Representation of the Moving Frame for Timelike Surfaces in 3-Dimensional Minkowski SpacetimePaul BrackenThe moving frame and associated Gauss-Codazzi equations for surfaces in Minkowski three space are introduced. A split-quaternionic representation is used to identify the Gauss-Weingarten equations with a Lax pair representation. This Lax pair representaion is calculated and given explicitly. …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,730 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Method for Edge Detection Using 2 Dimensional Gamma DistributionAli El-ZaartProblem statement: Edge detection is an important field in image processing. Edges characterize object boundaries and are therefore useful for segmentation, registration, feature extraction, and identification of objects in a scene. Approach: This study presented a novel method for edge detection using 2D Gamma distribution. Edge detection is traditionally implemented by convolving the image with masks. These masks are constructed … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,640 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,062 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleParallel Algorithms for String Matching Problem on Single and Two Dimensional Reconfigurable Pipelined Bus SystemsS. Viswanadha Raju, A. Vinaya BabuWe considered string matching on LARPBS and 2D LARPBS. This has applications such as string databases, cellular automata and computational biology. The main use of this method is to reduce the time spent on comparisons in string matching by using LARPBS. We investigated exact string matching and approximate string matching problems. For these two sub problems, we obtained O (n) … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,537 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA 2-Dimensional Model for the Transmission Dynamics of Schistosomiasis in the Human-Snail HostsG. Besigye-BafakiThe modes of transmission of schistosomiasis are considered. The transmission model is developed with an aim of establishing possible endemic equilibria within the community. Analysis of the model reveals that if the recovery rate β of human infectives and the death rate of snails δ are increased and if at the same time the contact rate κ of the human … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 6,510 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSimulations of Two-dimensional High Speed Turbulent Compressible Flow in a Diffuser and a Nozzle Blade CascadeK. C. Ng, M. Z. Yusoff, T. F. YusafThis research describes the development of a new structured 2D CFD solver for compressible flow. The high-speed turbulent flow in a diffuser and a cascade of nozzle blade is predicted using standard k-ε turbulence model. The new finite volume CFD solver employs second-order accurate central differencing scheme for spatial discretization and multi-stage Runge-Kutta time integration to solve the set of … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,552 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Quasi One-dimensional Simulation of a 4 Stroke Spark Ignition Hydrogen Fuelled EngineT. F. Yusaf, M. Z. Yusoff, I. Hussein, S. H. FongActive research and development of hydrogen-fuelled engine had been done for a few decades since hydrogen serves as a potential of infinite fuel supply. This paper discussed analytically and provides data on effects of compression ratio, equivalence ratio and spark timing of a hydrogen-fuelled engine as a guideline for the engine design. The change in the thermodynamic properties of the … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,887 accessesView PDFCite
