Heat Transfer Model for Embedded Thermocouple in Firefighter Glove

D. Mrugala, T. Riebeck, and W. Lang
Institute for Microsensors, -actuators and –systems (IMSAS)
University of Bremen
Bremen, Germany

The Integration of contact heat measurement with intelligent fire fighter gloves assumes parametric simulations with the heat transfer module of COMSOL. A thermocouple is embedded into high temperature protective layers of the glove and measures contact heat. This is done by by pressing ... 詳細を見る

Multiphysics Modeling of Nanoparticle Detection - Current Status and Collaboration Sought

D. Krizaj[1], I. Iskra[2], Z. Topcagic[1], and M. Remskar[2]
[1]University of Ljubljana, Faculty of Electrical Engineering, Ljubljana, Slovenia
[2]Institut Jozef Stefan, Ljubljana, Slovenia

We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector. We have successfully performed some experimental ... 詳細を見る

Modeling of Nonlinear and Non-stationary Multi-vortex Behavior of Electronic Crystal in Restricted Gemoetries of Nano Junctions

LPTMS URM8626
Université Paris-sud
Orsay, France

Electronic Crystals are common forms of organization of charge in solids. They appear widely from nano-structure semiconductors to synthetic organic conductors. Charge density wave, the best treated kind of electronic crystal, can readjust its elementary units by creation of topological ... 詳細を見る

Stress Analysis of an Electromagnetic Horn

B. Lepers
IPHC
Université de Strasbourg
Strasbourg, France

An electromagnetic horn is a device used in particle physics to produce a strong pulsed toroidal magnetic field and to focus charged particles toward a detector. A multiphysics analysis is performed to assess the stress level inside the horn structure. In steady state regime, the horn ... 詳細を見る

Research Site Leipzig
Reactive Transport Division
Leipzig, Germany

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import ... 詳細を見る

Xylophone Bar Magnetometry and Inertial-grade MEMS Optimisation: a Multiphysics Approach

H. T. D. Grigg, and B. J. Gallacher
Microsystems Group
Newcastle University
Newcastle upon Tyne
Tyne and Wear, UK

This paper presents ongoing research aimed at development of a MEMS magnetometer capable of nanoTesla sensitivity. Such a device would pave the way for inertial-grade MEMS IMUs. A resonant sensor is proposed, based on a Xylophone Bar sense element, and is analysed both directly and via ... 詳細を見る

Near-fields in Arrays of Triangular Particles: Coupling Effects and Field Enhancements

[2]Yerevan State University, Yerevan, Armenia
[3]Ulm University - Institute of Micro and Nanomaterials, Ulm, Germany

Surface enhanced Raman scattering (SERS) investigations of silver and gold triangular nanoparticles reveal strong field enhancements at the corners of the particles. Though the measurements were done at wavelengths far from the surface-plasmon resonance of the particles, large field ... 詳細を見る

Super-resolution Properties of the Maxwell Fish-Eye

D. Grabovickic, J. C. Gonzalez, J. C. Miñano, and P. Benitez
CEDINT
Universidad Politecnica de Madrid
Madrid, Spain

In this paper we present an analysis that shows the Maxwell Fish Eye (MFE) only has super-resolution property for some particular frequencies (for other frequencies, the MFE behaves as conventional imaging lens). These frequencies are directly connected with the Schumann resonance ... 詳細を見る
