CMOS Based Atom Chips for Sensor Applications

Ph. Neuman [1], A. Nemecek [1], C. Koller [2]
[1] Department for Micro-and Nanosystems, University of Applied Sciences Wiener Neustadt, Austria
[2] Department for Micro-and Nanosystems, University of Applied Sciences Wiener Neustadt, Austria, and School of Physics and Astronomy, University of Nottingham, Nottingham, UK

Ultra-cold atomic systems have proven over the last decade to be a excellent platform for the realization of quantum sensors, quantum computation or quantum simulation applications. A special implementation of this technology is the so called atom chip, where the magnetic fields ... En savoir plus

Coupled Optical & Thermal Model of a Silicon Microprobe

[1] Department of Atomic Physics, Budapest University of Technology and Economics, Budapest, Hungary
[2] MTA EK NAP B Research Group for Implantable Microsystems, Budapest, Hungary
[3] Óbuda University Doctoral School of Material Science & Technology, Budapest, Hungary

The topic of my work is modeling of a multimodal waveguide microprobe which is suitable for deep brain infrared stimulation. The goal of the research is the investigation of the therapeutic effect of optical IR excitation on biological active substances. In the physical model I ... En savoir plus

Multiphysical Simulation of Moved Data Cable

M. Raum [1]
[1] Friedrich-Alexander Universität, Erlangen, BY, Germany

In general this thesis is about the effects of mechanical stress on data cables in moved applications. If a data cable is loaded with different kind of forces and used within high frequency applications it is possible, that the geometrical changes may have an impact on the electrical ...

3D-model of an AC/DC Hybrid EHV Transmission Line to Analyze the Electrical Field along Insulators

D. Potkrajac [1], S. Papenheim [1], M. Kizilcay [1]
[1] University of Siegen, Siegen, Germany

To increase the power transfer capacity of existing lines, a transmission system operator in Germany plans to replace an existing 380-kV three-phase AC system into a bipolar HVDC system on the same tower that is called a 'hybrid line'. Due to the proximity of AC transmission systems and ... En savoir plus

Keep it Simple and Learn More - On a Stationary Study of a Time-Dependent Problem

B. Baumann [1], J. Schwieger [1, 2], U. Stein [1], M. Wolff [1],
[1] Hamburg University of Applied Sciences, Hamburg, Germany
[2] University of the West of Scotland, Paisley Campus, United Kingdom

Today’s driver hardware for High-intensity discharge (HID) lamps is bulky, expensive and not particularly energy-efficient. A downscaling of the devices seems possible by increasing the operation frequency from typically 400 Hz to some hundred kilohertz. However, efforts to design high ... En savoir plus

Simulation of the Additive Process of Forming 3D Products from HSLA Steel 09G2S

V. A. Kostin [1], G. M. Grygorenko [1]
[1] Department of Materials Science, E. O. Paton Electric Welding Institute, Kiev, Ukraine

The results of modeling of thermal fields, stresses, deformations and displacements in formation of an additive structure from structural low alloy steel for welding 09G2S on a substrate are presented. An interdisciplinary research computational package COMSOL Multiphysics® was used for ... En savoir plus

CFD Investigation of a Photocatalytic Multi-Tube Reactor for Indoor Air Purification

J. van Walsem [1], J. Roegiers [1], S. Lenaerts [1], S. Denys [1],
[1] Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

In industrial countries, people spend most of their time indoors. Stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality [1]. Integration or retrofitting of a photocatalytic oxidation or PCO reactor into continuous flow ... En savoir plus

A Multi-physical Approach of a Sterilization System for Aseptic Food Processing

Z. B. Jildeh [1], P. Kirchner [2], T. Rydlewski [2], C. Hollenbeck [2], T. Wagner [3], P. H. Wagner [4], M. J. Schöning [3],
