Research ArticleOpen accessPhrase in the titleEvaluation of the Severity of Mitral Valvular Regurgitation with Doppler Echocardiography Using Proximal Flow Convergence MethodPinjari Abdul Khayum, M.N. Giriprasad, P.V. SrideviProblem statement: Valvular regurgitation is recognized as the central cause of morbidity and mortality. Even though the clinician can detect the presence of regurgitation by mere physical examination; diagnostic methods become inevitable while estimating the severity of valvular regurgitation and in the transformation of cardiac chambers as in reaction to the volume overload condition. Lately, a promising new technology, the … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Evaluation of the Groundwater Influence on the Stress and Strain Behavior around a Tunnel by Analytical MethodsPierpaolo OresteThe presence of an aquifer in the soil causes a change in a relevant way of the stability conditions of a tunnel. The flow of water in the pores, in fact, modifies the stress and strain state of the soil and causes an increase in the thickness of the plastic zone. As a result the loads transmitted on the lining … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 30 Oct 2015 · 6,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of the Maximum Density Ratio Between Liquid and Vapor on Cavitating SimulationGuangjian Zhang, Weidong Shi, Ling Zhou, Desheng ZhangThe Filter-Based Model (FBM), which was built into CFX through CFX Expression Language (CEL) and a homogeneous cavitation model were employed to simulate cavitating flow around a 2D Clark-y hydrofoil. The effect of a maximum density ratio between liquid and vapor on sheet and cloud cavitating simulation was investigated. The results show that the maximum density ratio has a significant … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 21 Apr 2015 · 7,437 accessesView PDFCite
