Research ArticleOpen accessIn the abstractFINITE VOLUME METHOD OF MODELLING TRANSIENT GROUNDWATER FLOWN. Muyinda, G. Kakuba, J. M. MangoIn the field of computational fluid dynamics, the finite volume method is dominant over other numerical techniques like the finite difference and finite element methods because the underlying physical quantities are conserved at the discrete level. In the present study, the finite volume method is used to solve an isotropic transient groundwater flow model to obtain hydraulic heads and flow … …Journal of Mathematics and Statistics, Vol. 10, Issue 1 · 15 Feb 2014 · 7,108 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWeight of Evidence Allocates Mineral Depositional ZonesAbdullah A. Bokhari, Guang Dao HU, Rani FouadProblem statement: Yunnan province in general and Pulang area in particular is geological rich area which prevents field study in multi locations due to high risk outcrop. Approach: New technology such as Geographic Information System (GIS) and an ArcView extension module Arcweight of evidence (WofE) became very handy to provide safety for researchers and allow organization to control their budget. … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 6,981 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling of Activated Sludge Floc CharacteristicsIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem Statement: The activated sludge system needs to improve the operational performance and to achieve more effective control. To realize this, a better quantitative understanding of the biofloc characteristics is required. The objectives of this study were to: (i) Study the biofloc characteristics from kinetics-mass transfer interaction point of view by quantification of the weight of the aerobic portion of … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,422 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGait Optimization of Biped Robot during Double Support Phase by Pure Dynamic SynthesisNima Jamshidi, Mostafa RostamiThis paper deals with dynamic optimization of biped locomotion. The main focus of this research is motion optimization of double support phase. The optimization problem is dealt by using Pontryagins Maximum Principal. For motion optimization of double support phase, the closed kinematic chain has been considered to be opened at appropriate joint and the components of ground reaction forces has … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,127 accessesView PDF Cite

InvestigationOpen accessIn the abstractComparison of Green Roof Model Predictions with Experimental DataSergio Quezada-García, Manuela Azucena Escobedo-Izquierdo, Juan José Ambriz-García et al.In this study, the results of a green roof model are presented and compared with experimental data. Good agreement between simulation and experiment were found for different experimental conditions that were carried out in a controlled environment laboratory. The study of green roof heat transfer processes is important because it allows a better thermal design in buildings; the use of … …Energy Research Journal, Vol. 6, Issue 1 · 14 Jul 2015 · 7,225 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStability and Ergonomic Design Features of Tractor Mounted Hydraulic Elevator for Coconut HarvestingKishor Purushottamrao Kolhe, Ashok G. Powar, Amit D. Dhakane, Sham H. MankarProblem statement: The most important design criterion of mechanized device was safety; safety comprises both the safety of operator and safety of maintenance personnel. Failures and safety of harvesting platform of Tractor Mounted Hydraulic Elevator (TMHE) powered by tractor PTO was tested by finite element method for the mechanical harvesting of coconut orchards using digital ergonomic hart rate meter. The … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 20 Sep 2011 · 8,326 accessesView PDF Cite
