Non-Linear Passive Elastic Properties of the Left Ventricular Myocardium: Application of Finite Element Analysis to 3-D Geometry Obtained from Ultrasound Images
A finite element (FE) analysis and an optimization algorithm were employed to assess the nonlinear passive elastic properties of left ventricular myocardium in a canine mode. The three-dimensional...
In-Vitro Measurement of Static Contact Pressure Distribution in Synovial Joints
The objective of this presentation is, at first, to review the various approaches to the measurement of contact pressure distribution in synovial joints, and then to describe the development...
Comparative Time Domain Analysis of Some Available Analytical and Empirical Expressions for the Spatial Variability of Seismic Ground Motions
Simulations in space and time based on models for the spatial variability of seismic ground motions are generated. Displacement time histories are simulated through the spectral representation...
Time-Delayed Control of Nondispersive Continuous Systems
This paper deals with the noncollocated, time-delayed active point control of continuous systems. It considers systems of finite spatial extent which can be modelled by the undamped wave...
