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 ...

The knowledge of the light propagation through a nanometer-size aperture is crucial for Scanning Optical Near Field Microscopy (SNOM). In this work, we address a numerical study of the transmitted electric field through a SNOM probe. The influence of the wavelength is also studied. Our results show that the logarithmic power decreases linearly as a function of the aperture size, and the ...

In this paper we propose a finite element model (FEM), to solve the micro-magnetic equations. Two bi-dimensional test problems are treated to estimate the validity and the accuracy of this approach.

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.

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.

Thermoplastic polymers are frequently used in several industries, and represent the most important group of polymeric materials. During the injection moulding process, the cooling phase including solidification is often the most significant part of the manufacturing cycle. In this paper we study the coupling phenomena between the crystallization and the thermal kinetics in the polymer ...

In this paper, we describe the methodology of modeling Metal Organic Chemical Vapor Deposition. As a special case study we investigate the Ag deposit.

Various models, based on mass transfer and different isothermal adsorption equilibrium laws, are developed using COMSOL Multiphysics. These isotherms are representative of the adsorption of various pollutant-adsorbent systems frequently found in decontamination processes. Consequences on breakthrough curves are examined and possible applications to decontamination processes are discussed.
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.
