Passive Microsensor Based on LC Resonators for Substance Identification

D.A. Sanz Becerra[1], E.A. Unigarro Calpa[1], J. Osma[1], F. Segura[1]
[1]Universidad de los Andes, Bogotá, Colombia

A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital ... En savoir plus

A Non-Newtonian Model for Blood Flow behind a Flow Diverting Stent

G. Mach [1], C. Sherif [2], U. Windberger [3], A. Gruber [3],
[1] Vienna University of Technology, Cerebrovascular Research Group Vienna, Vienna, Austria
[2] Hospital Rudolfstiftung, Cerebrovascular Research Group Vienna, Vienna, Austria
[3] Medical University Vienna, Cerebrovascular Research Group Vienna, Vienna, Austria

Usually, when calculating the blood flow in cerebral arteries and intracranial aneurysms, blood is modeled as a Newtonian fluid, neglecting its shear-thinning behavior. Since flow diverting devices slow down the blood flow in the aneurysm sack, the accuracy of this assumption had to be ... En savoir plus

Performance Evaluation of the 19th Century Clipper Ship Cutty Sark: A Comparative Study

C. Tonry[1], M. Patel[1], C. Bailey[1], W. Davies[1], J. Harrap[1], E. Kentley[1], P. Mason[1]
[1]University of Greenwich, London, UK

The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship [1]. One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers [2]. They ... En savoir plus

Optimal Heat Sink Fin and Cold Lid Heights for Liquid Immersed Servers

A. Almaneea[1], J. Summers[1], H. Thompson[1], N. Kapur[1]
[1]University of Leeds, Leeds, United Kingdom

The system in this study is a closed server filled with Novac dielectric cooling liquid. The aim of this study is to find out the optimum value of the fin height and the cold lid height in order to reduce CPU temperature. A mesh accuracy investigation was conducted. The model set up in ... En savoir plus

Polyimide Thermal Micro Actuator

A. Arevalo[1], I. G. Foulds[2]
[1]Computer, Electrical and Mathematical Sciences and Engineering Division (CEMSE), King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[2]School of Engineering, Okanagan Campus, The University of British Columbia, Vancouver, BC, Canada

Joule heating is simulated in COMSOL Multiphysics® software for the electro-thermal micro actuator. The aim is to choose the optimal design parameters to get the largest possible in-plane displacement. The comparison between the different possible configurations will reveal the optimal ...

Thermal Integration of Coupled SOFC System with a High-Performing Metal Hydride Storage

A. Mossadegh Pour[1], A. Dhira [1], R. Steinberger-Wilckensa[1]
[1]Department of Chemistry, University of Birmingham, Edgbaston, Birmingham, United Kingdom

Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs ... En savoir plus

A Study of Laser Doppler Anemometer Using COMSOL Multiphysics^®

I. Lancranjan[1] and C. Gavrila[2]
[1]Advanced Study Centre, National Institute for Aerospace Research “Elie Carafoli”, Bucharest, Romania
[2]Technical University of Civil Engineering Bucharest, Bucharest, Romania

Laser anemometers based on application of Doppler Effect have been developed and are used in-flight, on aircrafts for measurement of air flow parameters, mainly its speed versus the airplane. The air speed measurements are vital for safe flights. The main basic idea of Doppler techniques ... En savoir plus

HazRes has developed a gas dispersion model in COMSOL, which takes into ... En savoir plus

Use of FEM in the Design of an HTS Insert Coil for a High Field NMR Magnet

E. Bosque[1]
[1]Applied Superconductivity Center, National High Magnetic Field Laboratory, Tallahassee, FL, USA

High temperature superconductors (HTS) allow larger current densities through coil wound electromagnets, which produce higher magnetic fields. A high field HTS insert demonstration magnet is being built with high field homogeneity (~1 ppm) for application in nuclear magnetic resonance ... En savoir plus
