A reduced-order method based on Approximated Lax Pairs (ALP) is applied to the integration of electrophysiology models. These are often high-dimensional parametric equation systems, challenging from a model reduction standpoint. The method is tested on two and three dimensional test-cases, of increasing complexity. The solutions are compared to the ones obtained by a finite element. The reduced...

Scattered-light photoelasticity provides a nondestructive approach for analyzing the stresses in a 3-D photoelastic model. However the applicability of scattered-light photoelasticity is quite limited. In this paper, a finite element scheme is proposed to simulate the fringe patterns resulted from scattered-light photoelastic experiment. Theoretical equations are derived to integrate the retard...

The paper reports design and FEM simulation comments on a fractional power three-phase induction motor with severe constraints as regards frame size and supply electric parameters. The simulation stage consists in magnetodynamic and transient analyses both in 2D and multilayer approach. The study takes into consideration different topologies (straight or skewed rotor slots, open or closed rotor...

The characterization of human gait using force platforms is one of the finest areas of biomechanics. Typically these force platforms are large, fixed and restricted to a laboratory environment. Therefore, a system for monitoring the human gait that is flexible, small-sized and can be installed in the actual sole of a shoe is desirable for many applications. We developed a portable, lowpower con...

A 3-D finite element model is used to simulate water jet spot welding. The simulation is validated using the experimental data obtained by one of authors with other workers. The simulations identify parameters which correlate well with the quality of the welds produced. In particular the levels of equivalent plastic strain (PEEQ) and shear stress directions are shown to predict whether or not t...

Surgical simulation is a promising technology for training medical students and planning procedures. One major requirement for these simulation systems is a method to generate realistic cuts through soft tissue models. This paper describes methods for cutting through tetrahedral models of soft tissue. The cutting surface follows the free form path of the user’s motion, and generates a minimal s...
