Research ArticleOpen accessIn the abstractHeat Transfer Numerical Analysis of a Thermochemical Solar ReactorA. Vázquez-Rodríguez, J. R. Varela-Ham, R. Avalos-Zuñiga et al.In this study a 2D transient temperature distribution in a one-dimensional thermochemical solar reactor of gas-particles is presented. The gas-particles medium is contained in a reactor where an endothermic chemical reaction of some oxide-metal at high temperature is expected to be occurred. The reactor receives the concentrated solar power on the reactor walls, or directly to the gas-particles medium. As … …Energy Research Journal, Vol. 5, Issue 2 · 6 Jan 2015 · 6,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING FAULT TOLERANT RESOURCE OPTIMIZED AWARE JOB SCHEDULING FOR GRID COMPUTINGK. Nirmala Devi, A. TamilarasiWorkflow brokers of existing Grid Scheduling Systems are lack of cooperation mechanism which causes inefficient schedules of application distributed resources and it also worsens the utilization of various resources including network bandwidth and computational cycles. Furthermore considering the literature, all of these existing brokering systems primarily evolved around models of centralized hierarchical or client/server. In such models, vital responsibility such … …Journal of Computer Science, Vol. 10, Issue 5 · 4 Jan 2014 · 6,896 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Gas Velocity and Temperature on Nitric Oxide Conversion in Simulated Catalytic ConverterSathaporn ChuepengProblem statement: Gaseous emissions from gasoline engine such as carbon monoxide, unburned hydrocarbon and nitrogen oxides were usually reduced in three-way catalytic converter simultaneously around theoretical fuel and air combustion. Engine speed and load and other parameters were varied over a wide range of operating conditions, resulting in different exhaust gas composition and condition intake into catalytic converter. This work … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 27 Jun 2012 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Modeling of Groundwater Flow in Karst Aquifer, Makeng Mining AreaF. M. Rani, Z. H. ChenProblem statement: Making iron ore is one of the largest mining projects in south east of china. Due to the development of mining activities in that site, it has become necessary to increase the depth of exploration. Increase the exploration depth makes the mining tunnels subjected to the karst water inrush. Approach: A hydrological and a hydrogeological model for the … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,467 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulink Model of Direct Torque Control of Induction MachineH.F. Abdul Wahab, H. SanusiDirect torque control (DTC) is one of the most excellent control strategies of torque control in induction machine. It is considered as an alternative to the field oriented control (FOC) or vector control technique. These two control strategies are different on the operation principle but their objectives are the same. They aim to control effectively the torque and flux. Torque … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Stability of a Certain Class of Linear Time-Varying SystemsM. De la SenThis study firstly considers the exponential stability of unforced linear systems of slowly time-varying dynamics. Possible switchings of the system structure to unstable dynamics during certain finite time intervals are admitted. The maintenance of global exponential stability does not necessarily require at most a finite number of switchings in the dynamics while infinitely many switches can also lead to stability. … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,935 accessesView PDFCite
