In this paper, the pulsatile flow of blood through an inclined catheterized stenosed artery is analyzed. Perturbation method is used to solve the implicit system of partial differential equations with suitable boundary conditions. Various analytical expressions axial velocity, flow rate, wall shear stress and effective viscosity have been derived with the help of MATLAB for understanding the fl...

Railways as a dimension of transportation infrastructure has been widely welcomed in developed and developing industrial countries because of the ability to carry heavy loads over long distances, more safety, less depreciation, less cost, less pollution, etc. Therefore, knowledge of the dynamic behavior of the railway is essential for designers and builders. It is very important to study the vi...

one of the most common methods for controlling and increasing maneuverability of projectiles, especially the ones which move at high altitude and in low density air, is using lateral or reaction jets. the resultant force of the reaction jet is related to the jet and flow parameters. for finding their relation experimental, numerical, and analytical methods have been used. in order to change the...

Abstract A physical model and a mathematical approach were developed to describe ponderomotive acceleration body pushed by plasma column of high-current arc in railgun. In contrast the previously published studies, generation was considered taking into account kinetics heavy particle fluxes non-equilibrium layer near vaporizating (ablating) rails phenomena heat mass transfer electric sheath at ...

Brechue, WF, Mayhew, JL, and Piper, FC. Characteristics of sprint performance in college football players. J Strength Cond Res 24(5): 1169–1178, 2010—To investigate sprinting strategy, acceleration and velocity patterns were determined in college football players (n = 61) during performance of a 9.1-, 36.6-, and 54.9-m sprints. Acceleration and velocity were determined at 9.1-m intervals during...

A half-car model with four DOF was established to simulate the system. On the basis of this model, Selfadapt Parameters Fuzzy-PID control method of the active suspension system is described. In such a model, vehicle speed, vehicle body vertical acceleration, suspension dynamic deflection, the body vertical acceleration and suspension dynamic deflection integrated feedback were used respectively...
