Kubo's generalized cumulant expansion theorem is used to derive a theoretical expression for the nuclear magnetic resonance (NMR) signal received from a fluid moving in a time-dependent magnetic field gradient. Described ...

The problem of femoral vibration during the reaming process in total hip arthroplasty is examined. These vibrations are modeled as the transverse vibration of a free-simple Euler-Bernoulli beam using a transfer matrix ...

With recent advances in myoelectric signal processing, powered prosthetic hands with myoelectric control have become more accepted among users of prosthetic hands. Inspite of this progress, the hands that are currently ...

Mathematical modeling of the electrical activity of a single cardiac cell and of strands of cardiac cells are problems of fundamental interest in the area of electrophysiology. New and increasingly comprehensive data on ...

A Lagrangian approach is used to perform an energy analysis on a nonlinear model of the human lung. Energy functions associated with the mechanics of breathing are obtained. Analytical expressions are derived for the work ...

This thesis presents a new method of myoelectric signal recognition. Myoelectric signals are electric signals generated by the motion of a person's muscle and can be used as control input for prosthetic hands. It uses ...

A 100 fold range of shear stress (.04-4 dynes/cm$\sp2$) was used to demonstrate that the level of shear used in conjugate enumeration assays affects the absolute magnitude of CTL-TC conjugates observed. Kinetic analysis ...

Pressure sores are a serious medical problem, which cause a great deal of economic and physical damage. The old method of skin color identification is not quantitative and is usually unreliable. Among various methods which ...

This study aims to determine the effect of shear stress on membrane potassium (K$\sp+$) permeability in vascular endothelial cells. Cultured monolayers of calf pulmonary artery endothelial cells, preloaded with $\rm ...

Epi-fluorescence video microscopy and digital image processing were used to evaluate the effects of three novel anti-platelet agents namely GT-12/I.2HBr (GT-12/I), A4.2HBr and IC, a series of compounds containing the ...
