Research ArticleOpen accessEvery word in the titleEfficient Rainfall Forecasting Using Sequential Momentum-Based Artificial Neural Networks for Urban Flood ManagementSherin K K, G. SuganthiUrban floods cause severe disruption in densely populated cities and damage essential public infrastructure. Rapid urbanization and weak drainage systems further increase the risk during heavy rainfall. Accurate short-term rainfall forecasting is required to support early warning and reduce losses. This research focuses on improving rainfall prediction accuracy using an Artificial Neural Network trained with a new optimizer named Sequential … …Journal of Computer Science, Vol. 22, Issue 4 · 9 Apr 2026 · 1,539 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSimple Improvement of Momentum Interpolation Equation for Navier-Stoke Equation Solver on Unstructured GridAdek TasriProblem statement: Pressure and velocity decoupling have been source of problem in solving Navier-Stokes and continuity equation particularly in complex collocated grid. The problem of pressure velocity decoupling is usually reduced by using momentum interpolation to calculate mass flux at face of control volume. Equation of momentum interpolation was derived by assumption that the face of cell is equidistant from … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,858 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NOVEL PRESSURIZED ZONAL MODEL USING THE MOMENTUM EQUATIONYao Yu, Ahmed Cherif MegriZonal models combine the simplicity of single and multi-zone models with the comprehensiveness of Computational Fluid Dynamics (CFD) models and thus become a better substitute to predict detailed thermal and airflow behaviors in building. Based on a geometric partitioning of a room into a number of subzones, these models give more accurate and detailed results than the single or multi-zone … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 25 Mar 2014 · 8,570 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTwo Source Emission Behavior of Helium Projectile Fragments in 84Kr Interactions at Around 1 GeV per nucleonManoj Kumar Singh, Arun Kumar Soma, Ramji Pathak et al.Problem statement: The emission of helium projectile fragments has been studied in 84Kr interactions with nuclei of the nuclear emulsion detector at relativistic energies below 2 GeV per nucleon. Approach: The angular distribution of helium projectile fragments in terms of transverse momentum could not be explained by a straight and clean-cut collision geometry hypothesis of Participant-Spectator (PS) Model. Results: Therefore, … …Physics International, Vol. 1, Issue 2 · 31 Dec 2010 · 6,791 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFour 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 · 7,057 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTarget Fragmentation at 4.5 a GeV/c in 24Mg and 28Si with Emulsion InteractionA. Abd El-DaiemThe correlations between the multiplicity distributions and the projectile fragments, as well as the correlations between the black and grey fragments were given and the analysis of the projection of the transverse momentum, angular characteristics and azimuthal alignment were analyzed for the presence collective flow of nuclear matter in interactions of 24Mg and 28Si with AgBr emulsion nuclei at 4.5 … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Method for Constructing the Coefficients of Pressure Correction Equation for Colocated Unstructured GridsR. Rafee, H. RahimzadehOne of the important equations in numerical solution of Navier Stokes equations is the pressure correction equation. In this article, a new method for constructing the coefficients of this equation for colocated unstructured meshes is proposed. This method is based on momentum interpolation. The method is compared with the approach adopted in literature. The complete discretization of the Navier Stokes … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,137 accessesView PDFCite
