Using magnetic resonance images, a model was created of an atherosclerotic plaque in a patient. A fluid-structure interaction analysis was then carried out in order to determine principal stresses in the protective fibrous cap. Results indicate stresses at high blood pressure in excess of 300 kPa, the established cap rupture strength. The technique could prove to be of great value to ...

Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery such that the mass transport of glucose around all the micro-electrodes can be improved and hence output ...

The evaporation process of microscopic drops was investigated by depositing them onto atomic force microscope (AFM) cantilevers and measuring the deflection of the cantilever in response to the presence of the drop. We could thus improve a previously presented FE simulation model by comparing the simulations of the cantilever’s transversal deflection to 3-D images of the cantilever’s ...

Primary reference standards for determining absorbed dose to water in radiotherapy beams used at cancer clinics and hospitals ultimately must make reference to the temperature change in water produced by ionizing radiation. The most direct experimental technique for this purpose is water calorimetry. Since the dose distributions delivered by such beams are nonuniform, temperature signals ...

Growing consumer demand for nutraceuticals has stimulated interest by food companies to increase levels of these health-promoting compounds. Thermal processing of canned foods in a retort produces a unique problem: some of the nutraceuticals are highly sensitive to temperature, and require accurate parameter estimates to predict their fate during processing. Error in temperature measurement due ...

Mit Hilfe des Softwareprogramms COMSOL zur Modellierung physikalischer Vorgänge wurden die Polarisationseigenschaften einer mikrostrukturierten Singlemodefaser untersucht. Ausgangspunkt der Simulationen waren experimentelle Untersuchungen, nach denen diese Faser eine ungewöhnlich starke Doppelbrechung aufwies. Die Doppelbrechung der Faser und damit ihre Fähigkeit zur Polarisationserhaltung ...

The Magnetic Refrigerator (MR) is a special type of refrigerator with potential to reduce the energy consumption of household refrigeration by a factor of two or more. To conduct numerical analysis of an experimental MR, a mathematical model was developed. The model solves the coupled Navier-Stokes and heat transfer equations which describe the physical phenomenon occurring within the MR. To ...

In this presentation we present our analysis of the PARC Nanocalorimeter. Calorimetry is basically the measuring of heat of chemical reactions or physical changes. Nanocalorimetry is Calorimetry at the Nanometer scale. The PARC Nanocalorimeter is a special type of Calorimeter, it consists of arrays of Nanocalorimeters. The PARC Nanocalorimeter is intended to be used for screening biochemical ...

It has become common place to use micro-electromechanical systems (MEMS) to evaluate the chemical properties of solutions. However, such microchips have not yet been applied to the analysis of radioactive solutions, for the purpose of nuclear safeguards, in the nuclear reprocessing industry. Implementing MEMS in this area results in a reduced volume of the sample to be analysed. This has many ...

In this presentation we will show how to partially model a grand piano action. Then we will apply different touches to this virtual action and try to hear any difference. --------------------------------- Riccardo Ferrari was one of the keynote speakers at the COMSOL User's Conference, fall 2005 in Milano
