FINITE ELEMENT AND IMAGING APPROACHES TO ANALYZE MULTISCALE ELECTROTHERMAL PHENOMENA
… at submicron to centimeter scales. Typically, finite element methods (FEM) are used to calculate the temperature profile in devices and ICs with complex geometry. By comparing theory and experiment, important material parameters and device characteristics are extracted. In this work we combine …

Analytical representation and finite element analysis of magnetically-geared permanent magnet machines
… or analytical frameworks. The former such as finite element methods (FEM), although powerful, is expensive and time-consuming, while the latter approach like flux-tube based models provide a flexible yet reasonable solution for preliminary designs and optimizations.

Stress and structure evolution during Volmer-Weber growth of thin films
… coalescence was modeled analytically and by finite element methods (FEM) as the energetic balance between interfacial energy reduction and strain energy generation resulting from grain boundary formation. The magnitude of the island-coalescence stress calculated using FEM was found to …

Compact representations for fast nonrigid registration of medical images
… interiors and smooth boundaries. We create methods to represent such regions compactly using tetrahedra. Unlike voxel-based representations, tetrahedra can accurately describe the expected smooth surfaces of medical objects. Furthermore, the interior of such objects can be represented using …

Full-wave modeling of lower hybrid waves on Alcator C-Mod
… of full-wave simulation codes based on Finite Element Methods (FEM) used in support of experiments carried out on the Alcator C-Mod tokamak. In particular, two non-linear problems have been adressed: high power antenna-plasma coupling and current drive (CD). In both cases, direct …

Vibro-acoustics of porous materials with periodic inclusions
The design based on periodic elements is a powerful strategy for the achievement of lightweight sound packages and represents a convenient solution for manufacturing aspects. Several theoretical models exist to study the physical behavior of porous and poro-elastic media, and the most complex ones …

Modeling And Detection Of Uterine Contractions Using Magnetomyography
… domains for any uterine shape. We use finite element methods: FEM) to solve our model, and we illustrate our approach by presenting a numerical example to model a uterine contraction at term. Our results are in good agreement with the values reported in the experimental technical …
