A higher order boundary element method (HOBEM) is presented for inviscid flow passing a lifting body. In addition to the integral equation used velocity potential, similar derived and tangential on body surface. Higher elements are discretize surface, which ensures continuity of slope at nodes. The potential also expanded using shape function, in unknown coefficients involve velocity. expansion...

Peskin’s Immersed Boundary (IB) method is one of the most popular numerical methods for many years and has been applied to problems in mathematical biology, fluid mechanics, material sciences, and many other areas. Peskin’s IB method is associated with discrete delta functions. It is believed that the IB method is first order accurate in the L∞ norm. But almost none rigorous proof could be foun...

A Green-Kubo expression for the nonequilibrium correction to the velocity distribution function is studied in a molecular dynamics simulation for systems interacting through a 6-12 potential and undergoing linear shear. As a function of velocity, the first correction to the distribution function has a form similar to what would be obtained from the Boltzmann-Enskog equation, although the amplit...

by virtue of a complete set of two displacement potentials, an analytical derivation of the elastostatic green’s functions of an exponentially graded transversely isotropic bi-material full-space was presented. three-dimensional point-load green’s functions for stresses and displacements were given in line-integral representations. the formulation included a complete set of transformed stress-p...

based on the “aggregate demand” theory, monetary policies are designed with the aim of achieving desirable level of macroeconomic goals through affecting the stock of money supplyand income velocity of money. thus, the velocity (v)-as well as money supply - has significant impact, particularly on rate of inflation through expansionary or contractionary monetary policy. to focus on the velocity ...

In order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive M-mode and Doppler echocardiography, an analytic study was designed in a university hospital in Sari. We have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. Peak flow velocit...

By orbit-limited motion (OLM) theory and the kinetic model, currents carried by electronsand ions on the dust grain are obtained and the effects of temperature and drift velocity of ions on thedust grain electrical potential are considered. The calculations were performed for finding the role of densities of dust grains and ions on the dust grain electrical potential which is the ma...

background: sickle-cell disease (scd) is an inherited hemoglobin childhood disorder, frequently complicated by pulmonary hypertension and cardiac involvement. cardiovascular events and complications are the leading cause of mortality and morbidity in patients with scd. tissue doppler imaging and the myocardial performance index (tei index), are simple indices for the assessment of the cardiac f...
