In spite of its low throughput, Patch-Clamp is the established method for intracellular measurements of the transmembrane potential. To address this problem, we have developed new biosensor-chips with micro-structured needle electrodes (MNEs). MNE-penetration of single cells growing on the MNE-tips leads to a situation comparable to the whole-cell mode in classical Patch Clamp. MNE-penetration ...

This model studies a portion of the vascular system of a normal person, in particular the left ventricle and the mitral valve of the heart. The flowing blood applies pressure to the ventricle before, after and specially during the contraction process of the heart, thereby deforming the structure.

FEMLAB was used to aid in the design of a novel temperature management system. The system under consideration is a heat sink consisting of a carbon foam block brazed to the inside of an aluminum enclosure. The high thermal conductivity carbon foam is structurally reinforced and filled with a phase change material. A phase change material (PCM) is a substance which releases a large amount of ...
Low-pressure glow discharges are of topical interest for a lot of technological applications like plasma light sources, plasma processing for surface modification, and plasma chemistry. Therefore, a detailed understanding of the fundamental processes of glow discharges is required to e.g. optimize the discharge parameters in these plasma applications. Theoretical investigations can help to ...

Les décharges luminescentes à pression atmosphérique sont étudiées expérimentalement en laboratoire pour la valorisation des alcanes et notamment la production d'hydrogène à partir du méthane. La modélisation des dispositifs usuels est complexe compte tenu de l'aspect non stationnaire des décharges. Afin d'évaluer le poids des paramètres de réglage d'un réacteur nous avons ...

Electron interferometry using the Aharonov-Bohm (AB) effect finds many applications in industrial areas such as future nanocomputer technologies, physical random number generators, electron phase microscopy and holography, to name just a few. The presence of a confined magnetic field surrounded by the interferometer arms, as originally proposed by Aharonov and Bohm is however a source of ...
Computations of the earth’s and other solar planets’ magnetic moments with the aid of a FEMLAB electromagnetic module
Retired, Hughes Space & Communications Co. (Now Boeing Co.)
Computations have been performed of Earth’s and other solar planets’ magnetic moments with the aid of a FEMLAB Electromagnetic Module. The FEMLAB library has a specific program that calculates magnetic field strength and distribution resulting from a circular current source. This program has been adapted with 38 concentric loops to simulate the conductive currents circulating within the ...

Flow behaviour of phosphorus-deoxidised copper in plane-strain hot extrusion with an insertion in the die has been studied through a finite-element model consisting of fluid dynamics and heat transfer approaches. The billet material is considered as rigid-visco-plastic and rate-sensitive. A dynamic viscosity, which is strain-rate and temperature dependent, has been integrated into the model. ...

In this paper, after a brief presentation of our company, we will detail our technology and the importance of the simulation step. In the same time, we will describe different levels of FEA (Finite Element Analysis) we have followed and we will conclude on the best balance, for our industrial target, between complexity of models and accuracy of results.

This paper presents and discusses HazRes’ research and results associated with the simulation and modelling of hydrogen release and dispersion events in indoor enclosed environments, using COMSOL Multiphysics. HazRes has developed a gas dispersion model in COMSOL, which takes into account the effects of buoyancy, localized ventilation effects and turbulence generated by obstacles on the ...
