Markus Zahn received all his education at MIT, was a professor in the Department of Electrical Engineering at the University of Florida, Gainesville from 1970-1980, and then joined the MIT Department of Electrical Engineering and Computer Science faculty in 1980. He works in the ... En savoir plus

Microfluidics-based mixing has been widely used in various areas such as chemical engineering, biomedical engineering and materials science. The micromixer can be strategies into two categories as passive and active method depending on the mixing principle. Magnetic mixing integrated ... En savoir plus

Currently, there is a great interest in the study of gels, especially their transport or release properties. Hydrogels have countless definitions, but generally speaking, they are hydrophilic systems with a three-dimensional structure that tend to swell and hold large amounts of water ... En savoir plus

This paper presents and discusses the first phase results of a wide ranging project concerning the study and prediction of the efficiency and energy performances of natural ventilation systems existing inside historic buildings. The air flow patterns, air temperature and air velocity ... En savoir plus

Autoliv Livbag is a company specialized in the development and manufacturing of gas generator for airbags based on pyrotechnic and compressed gas technologies. In this context, specifications of the product are very particular. Indeed, the gas generator needs to be airtight for several ... En savoir plus

We present a novel method for concentrating and focusing small analytes by taking advantage of the nonuniform ion distributions produced by thick electric double layers (EDLs) in nanochannels with heterogeneous surface charge. Specifically, we apply a voltage bias to a gate electrode ... En savoir plus

Our current research is focused on thermal Marangoni instabilities in sessile ethanol drops which develop spontaneously during evaporation. Our current problem for numerical model is 3D unsteady with moving interface of a sessile drop under forced evaporation and showing internal flow ... En savoir plus

It has already been demonstrated that fluid models can be used to simulate two-dimensional axisymmetric inductively coupled plasma via implementation in the COMSOL (multi-physics simulation software) platform. In this study, we improved the model and simulated a large scale magnetized ... En savoir plus

In circuit breakers, short-circuit breaking involves extreme conditions linked to the presence of an intense electric arc. This requires the use of specific electrical contacts consisting of a contact tip and its support. SCHNEIDER ELECTRIC uses the resistance sintering technique for the ... En savoir plus

Convective instability in a thin liquid layer is observed in many technical systems [1] and is of interest to the self-organization theory. To date, however, only simple problems with the convection between flat plates are well studied [2]. In real systems and devices, convective flows ... En savoir plus
