Research ArticleOpen accessAll words, across the recordNumerical Treatment of the Mathematical Models for Water PollutionF. B. Agusto, O. M. BamigbolaTo evaluate the environmental impact of pollution, mathematical models play a major role in predicting the pollution level in the regions under consideration. This paper examines the various mathematical models involving water pollutant. We also give the implicit central difference scheme in space, and a forward difference method in time for the evaluation of the generalized transport equation. …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,382 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordNumerical Study of the Moving Boundary Problem During Melting Process in a Rectangular Cavity Heated from BelowY. Jellouli, R. Chouikh, A. Guizani, A. BelghithWe present an analysis of the melting process in Phase Change Materials (PCM) in a horizontal cavity heated from below, driven by the coupling of transient heat conduction in the solid phase and steady state laminar natural convection in the liquid phase with one of the boundaries of the solution domain that moves. We state the problem in the Cartesian … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,391 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCrack Analysis of Concrete Arch Dams Using Micro-Planes Damage Based Constitutive RelationsM. Labibzadeh, S.A. SadrnejadAmong the various numerical simulating models of plane concrete, the micro-planes models have an excellent position. These models are not as complicated as microscopic models such as discrete particles models and do not have the shortcomings of macroscopic models based on the stress or strain invariants. The object of this study is the application of author's recently developed micro-planes damage … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 6,978 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordNumerical Study of the Behavior of Single-Sided Protruding SlabsReza Salehi, Abbas Akbarpour Nikghalb RashtiDue to the high seismicity of our regions, engineers have always sought to provide various solutions to improve the performance of buildings and consequences control of powerful earthquakes. Building Lighting is one of the methods used to reduce earthquake forces. The use of prefabricated slabs is one of the ways to reduce the dead load of a building. In this … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 4 May 2018 · 8,178 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDesign and Manufacturing of a Custom Skull ImplantJuan Felipe Isaza Saldarriaga, Santiago Correa Vélez, M.D. Adolfo Cumplido Posada et al.Problem statement: Cranioplasty is defined as a neurosurgical procedure to cover an injured bone in the skull. This procedure is carried out in order to protect and restore intracranial structures and to restore the appearance and psychological stability of the patient. Advances in medical imaging, such as MRI and CT, have allowed the 3D reconstruction of anatomical structures for several … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 17 Mar 2011 · 9,565 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordNumerical Investigation Into The Behavior of Circular Pad Shallow Foundations Supported By Geogrid Reinforced SandS. M. Marandi, M. H. Bagheripour, R. Rahgozar, A. R. GhirianThis study seeks to widen the pool of knowledge on the use and characteristics of geosynthetics, specifically in the area of circular foundations supported by geosynthetic reinforced sand. The main objective of the work was to increase the awareness of circular foundation systems and thus increase the accuracy of current laboratory methods. Also, compare the results with that of previous … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,153 accessesView PDF Cite
