Greenhouses need heating supply most of the time of a year. Their heating demands are high and economical heating systems are very important for this kind of facilities. Horizontal ground source heat pump systems are getting more interest last years for being easy to apply and low ... En savoir plus

This paper reports the structural solid mechanic simulation of a MEMS out-of-plane platform that provides thermal and electrical isolation for a device built on it. When assemble, the platform lifted for approximately 400 μm above the substrate level. A mechanical stress analysis is then ... En savoir plus

Alexander Frey received his M.A. degree from the University of Texas, Austin, in 1994, the Dipl. Phys. degree from the University of Wuerzburg, Germany in 1997 and the PhD from the Saarland University, Germany in 2010. In 1997 he joined Research Laboratories of Siemens working on the ...

Introduction: RFID system uses a Transponder and the near field communication (NFC) antenna and a matching circuit (Figure-1) in which at least latter two must be optimally designed for a higher efficiency. Typically, RFID antennas are flat inductive coils with 2 to 4 turns and are ... En savoir plus

Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is ... En savoir plus

Bolometers are used in a number of applications including night vision cameras, astronomy, and particle physics to measure the power of incident electromagnetic radiation. The general principle of operation is shown below: a strip of conducting material is exposed to incident ... En savoir plus

HazRes has developed a gas discharge and dispersion model in COMSOL which takes into account the effects of localized wind profiles and turbulence generated by buildings, structures and terrain on the dispersion of gases in question. The main focus of this work is to develop and provide ... En savoir plus

We demonstrate cartogram construction, where a geographical map is distorted to represent some measure, for example population, while trying to keep the shape of regions recognizable. We then apply this cartogram construction technique to optimize thermocouple locations. A heat ... En savoir plus

This paper summarizes the main features of the on-interposer micro-thermoelectric sensors (hereafter denoted by µTES) derived by means of simulations done with COMSOL Multiphysics® software. µTES are thermal sensors based on the Seebeck effect which converts thermal flow into electrical ...

In this project, we are aiming towards the development of an impedimetric biosensor based on nanoporous silicon structures for the detection of small molecular size and low weight food toxins (like Aflatoxin). Existing sensors for such toxin detection fail to achieve high sensitivity ... En savoir plus
