Sensors for industrial applications require electro-magnetic compatibility protection elements. It is an advantage to incorporate the protection elements directly in the application specific integrated circuit (ASIC). These protection elements however experience significant heating. It ...

We present an easy-to-use toolbox for the automated generation of reduced-order mixed-level models for the evaluation of squeeze-film damping in microelectromechanical systems. The toolbox is programmed in JAVA and heavily exploits the functionality provided by the COMSOL API. The ... En savoir plus
This paper deals with the design of a viable thermal management solution using La5Ca9Cu24O41 layers for heat channeling. The simulations are carried out with the finite element method using COMSOL Multiphysics Heat Transfer Module. COMSOL 4.2 was used to model and optimize silicon ... En savoir plus
We deal with Liquid Crystal Elastomers (LCEs) having hybrid alignment (HNEs), that is, fabricated with a given non-homogeneous nematic orientation. For such a materials, permanent distortions induced by deswelling can be compensated by those resulting from cooling below the transition ... En savoir plus
The vibration of the walls of brass wind instruments has been a subject of study in the field of musical acoustics throughout the last decades. The amplitude of such vibrations, stimulated by the oscillating air pressure inside the instrument bore, is very small compared to the ... En savoir plus
The field quality requirements of most particle accelerator magnets are very tight and, therefore, very precise simulations are needed to accurately calculate these devices. CERN\'s ROXIE code is widely used as a reference software to calculate normal conducting and superconducting ... En savoir plus
In principal, the calculation of the magnetic state inside a magnetic object requires the evaluation of the field in the entire unbounded space. With finite element methods restricted to finite domains, commonly auxiliary domains are employed which result in a non-physical cut-off. Not ... En savoir plus
Otoacoustic emission (OAE) tests provide an objective examination of the cochlear function. However, the validity of OAE tests is affected negatively by calibration errors. This report sheds light on the evanescent waves arising at the interface between the OAE probe and the ear canal, ... En savoir plus
The simulation of heat and moisture transfer represents an essential resource in designing energy efficient buildings. In this paper a time-dependent wall model, consisting of several homogeneous domains, with third-type boundary conditions imposed on the surfaces, is implemented in the ... En savoir plus
The article presents the process of verification of the passive magnetic bearing by the Comsol Multiphysic program. There is shown construction of the radial passive magnetic bearing PMB60x85x20-5, which was designed in the Military University of Technology. The distribution of the ... En savoir plus
