Elastic and poro-elastic models of ventricular dilatation in hydrocephalus are presented in this paper. An important result was the accumulation of fluid capping the horns of the ventricles. This indicates the importance of interstitial fluid in calculating of the deformation of the brain.
Low Frequency Electromagnetic Wave Propagation in Large Cavities, Study of the Cavity of Titan after the Cassini-Huygens Mission

CETP/IPSL-CNRS 4, Saint Maur, France
The propagation of low frequency electromagnetic waves in the cavity of celestial bopdies with ionospheres has been studied, namely for inferring thunderstorm and lightning activity. The measurement of resonant states provides useful information for the analysis of the electric environment in the cavity. We present a 3D finite element model of the cavity, compute the lowest eigenfrequencies ...
L'ecole Nationale Supérieure de Physique de Grenoble
The students at ESPNG have, since 2002, been using COMSOL Multiphysics in order to master physical phenomena and the finite element method. We developed several projects based on the modeling of physics phenomena, and, in this paper, we present projects based on Physical Vapor Transport and Magnetic Levitation. --------------------------------- Keynote speaker's biography: Jean-Marc ...
Boundary Conditions Identification for Thermostatic Cauchy Problem by Minimizing an Energy-like Function
LDMS, UMR CNRS-INSA 5006, ISTIL - Université Claude Bernard, Lyon
An energy-like error function is introduced in the context of the ill-posed problem of boundary data recovering, which is commopnly known as a Cauchy problem. Here the problem is converted into an optimization problem. Numerical simulations highlight the efficiency and robustness of the proposed method.

In this paper, we investigate the compressional wave generation in droplets and use different techniques to correlate the compressional wave generation to the shape of the droplets. Results show a good correlation between eigenmodes predicted by the theory and those experimentally observed.

The so-called opposite electrode pair measurement strategy is adapted in a filtration/expression cell filled with a model material packed bed. In this paper, we investigate the electrical properties of a packed bed, with particular emphasis on its overall conductivity. As a special case study we treat potassium chloride solutions, using model materials of different particle sizes.
Multiphysics Simulations of Tunneling Current Modulation using Ultra-Thin Membranes Micromachined on SOI

Institute of Microelectronics, Electromagnetism and Photonics, Grenoble
In this paper, we study a novel type of NEMS - tunnel junctions mounted on thin membranes. Mechanical stress applied to the junction induces changes in the height and length of the barrier, allowing the modulation of the tunnelling current.

This paper summarizes the numerical contribution to a project for the detection of bioparticles present in a small volume of a liquid sample. Dielectrophoresis (DEP) is used to enhance their transport toward the surface of a detector. The mathematical model is composed of the electrokinetics equation for the DEP force-field calculation, and the advection-diffusion equation for the particle ...
