A computer model for simulating pressure and flow propagation in the human arterial system is developed. The model is based on the one-dimensional flow equations and includes nonlinearities arising from geometry and material properties. Fifty-five ar

Previous data from our laboratory have demonstrated that uterine blood flow (UBF) and uterine arterial smooth muscle tone vary regularly during the estrous cycle of the cow. Uterine blood flow is highest and uterine arterial tone is lowest at estrus,

This paper considers a finite element method to characterize blood flow in the human arm arteries. A set of different pressure waveforms, which represent normal and diseased heart pulses, is used for the proximal boundary conditions, and a modified W

The development of turbulence under both steady and pulsatile flow through models of arterial stanoses was studied experimentally. Stenoses were represented by three severely constricted rigid-walled models with different shapes. Model geometries inc

A relatively simple analytical model is developed to investigate the interaction between blood flow through an arterial stenosis and the corresponding collateral and peripheral vascular beds. The model utilizes a realistic non-linear pressure-flow re

For various types of linear and nonlinear functional differential equations null controllability (local or global) is established. Previously it was believed that for a broad class of nonlinear equations local null controllability was implied by the
