Research ArticleOpen accessIn the abstractInvestigation of Abutment Displacement of a Full Height Integral Bridges in Dense Granule BackfillM. H. Alizadeh, A.R. Khalim Rashid, Zamri Chik, S. M. MirhosseinyProblem statement: In this study, the behavior of abutment wall in full height frame integral abutment bridges was investigated. It was seen that the effect of backfill soil resistance on behavior of abutment wall movement is mostly neglected in previous studies. In this research, the final bridge superstructure displacement under temperature-induced forces was formulated. In addition, according to the final … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simulation Model Estimates of the Intercropping Advantage of an Immature-Rubber, Banana and Pineapple SystemMohamadu Boyie Jalloh, Wan Sulaiman Wan Harun, Jamal Talib et al.Problem statement: Intercropping has been shown to have many advantages but it is fallacious to conclude it is always a better cropping system. Little is known about a new double-hedgerow intercropping of rubber, banana and pineapple in relation to its effects on growth and yield of the component crops when compared to their monocrops. Simulation modeling offers a cheaper and … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Surface Treatment on Fatigue Life of Cylinder Block for Linear Engine using Frequency Response ApproachM. M. Rahman, A. K. Ariffin, S. Abdullah et al.Objectives: This study was focused on the finite element techniques to investigate the effect of surface treatment on the fatigue life of the vibrating cylinder block for new two-stroke free piston engine using random loading conditions. Motivation: An understanding of the effects related to the random loading is necessary to improve the ability of designers to accurately predict the fatigue … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,142 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTHE USE OF DIFFERENT LEVELS OF MULTI-ROOM MODELING APPROACH-APPLICATION TO BUILDING POLLUTION TRANSPORT AND EFFICIENCY OF OFF-HOUR VENTILATIONAhmed Cherif MegriSeveral building simulation programs have been developed for design, analysis and prediction of the distribution of temperature, airflow and heat transfer between inside and outside of a building and/or between different zones of the same building. These programs are categorized as mono-zone models, multi-room models, zonal models, Computational Fluid Dynamics (CFD) models and multi-zone models. The number of computer programs … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 25 Mar 2014 · 7,773 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling and Simulation of a Novel Switched Reluctance Motor Drive System with Power Factor ImprovementG. Venkatesan, R. Arumugam, M. Vasudevan et al.This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,099 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMolecular Docking of New Active Compounds Towards the Acetylcholinesterase EnzymeLemaoui Tarek, Hammoudi Nour El Houda, Benguerba Yacine, Attoui AyoubMolecular docking is a key instrument in structural molecular biology and computer-assisted drug design. The objective of ligand-protein docking is to expect the main binding mode(s) of a ligand with a protein of known three-dimensional structure. Effective docking methods search high-dimensional spaces effectively and finding a scoring function that correctly ranks candidate dockings (Morris et al., 2008). In this study … …Current Research in Bioinformatics, Vol. 8, Issue 1 · 27 Feb 2020 · 11,408 accessesView PDFCite
