Computational Study on Transcutaneous Frontal Nerve Stimulation: Simplification of Human Head Model

E. Salkim [1], A. N. Shiraz [1], A. Demosthenous [1],
[1] Electronic and Electrical Department, University College London, London, UK

I. INTRODUCTION Migraine is a neurological disorder which affects nearly 15% of the population and it has been estimated that the European Community spends about €27 billion in a year. Its symptoms may be categorized as attacks of often severe, throbbing head pain with sensory ... Read More

Modeling Of A Single Pulse Electric Discharge At Sphere/Flat Interface By Coupling Contact Multiphysics And Phase Transformations

G. Maizza, P. Di Napoli, and R. Cagliero
Dipartimento di Scienza dei Materiali ed Ingegneria Chimica, Politecnico di Torino, Torino, Italy

Contact electro-thermal phenomena are of great theoretical and technological interest to a large number of processing applications, such as spot welding, current-assisted sintering, electrical circuitry (switches) and motors. A model has been developed, aiming at predicting physical and ... Read More

Modeling of Space-Charge Effects in 3D Thermionic Devices

The formation of space charge clouds is a well known problem that affects thermionic emitters in regimes of high current emission. Although some analytical models have been presented, suitable for 1D geometries, the modeling of the problem in complex 3D structures remains a challenge due ... Read More

Dynamic Simulation of a Coaxial Magnetic Gear Using Global ODE's and the Rotating Machinery, Magnetic Interface

M. Ostroushko [1], W. Zhang [1], W. M. Rucker [1],
[1] Institute of Theory of Electrical Engineering, University of Stuttgart, Stuttgart, Germany

The coaxial magnetic gear is a good alternative to classic mechanical gears. The magnetic gear has high mechanical durability, overload protection and lower noise, than a mechanical gear [1,2]. A static model of a magnetic gear [3,4] is used for simulation of the magnetic fields and ... Read More

Parametric Model Of An Air-Core Measuring Transformer

D. Herceg
Faculty of Technical Science, Novi Sad, Serbia

Power grid voltages and currents may be distorted due to presence of harmonics. Measurements of such voltage with harmonics may be performed using newly developed instrument with a small air-core transformer based probe as the input unit. The probe must be shielded against unknown ... Read More

Temperature Distribution in High Voltage Dummy Cable

G.Y. Sun[1], O. Sekula[1], and C. Albanbauer[1]
[1]Brugg Kabel AG, Brugg, Switzerland

A 2D model of coupled electricthermal application is used to calculate the temperature distribution in a high voltage dummy cable laid in free air, where no high voltage is applied. Resistive loss heats the cable while the surrounding air cools it down. The steady-state condition is ... Read More

Numerical Simulation of a Human Body Subjected to Electrostatic Fields for Study of the Turin Shroud Body Image

G. Fanti[1], L. Matordes[1], V. Amoruso[2], M. Bullo[1], F. Lattarulo[2], G. Pesavento[1]
[1]Dip. di Ingegneria Industriale, Università di Padova, Padova, Italy
[2]Politecnico di Bari, Bari, Italy

The TS (Turin Shroud) [1,2] is a fine linen fabric showing a not yet explainable [3] double body image of a scourged and crucified man stabbed on the side. Many hypotheses have been formulated without success [4] and perhaps the most reliable is one correlated to the Corona Discharge [5] ... Read More

Electromagnetic Well Logs Simulated with the COMSOL® RF Module on a Cluster new

D. Swaminathan[1], G. Minerbo[1], K. Pathak[1]
[1]Drilling and Production Group, Schlumberger, Houston, TX, USA

Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show ... Read More

Simulation and Verification of a Capacitive Proximity Sensor

T. Schlegl, and H. Zangl
Graz University of Technology
Graz, Austria

State of the art proximity sensors are most often based on optical or tactile methods. Although these sensor systems are widely used (e.g. clamping protection) the reveal several drawbacks. Most optical sensors need a line of side whereas tactile sensors cannot be used to determine a ... Read More

Sensitivity Optimization of Microfluidic Capacitance Sensors

S. Satti[1], M. Baghini[1]
[1]Indian Institute of Technology Bombay, Mumbai, Maharashtra, India

As a part of a lab-on-chip-device, more often it is required to measure dielectric constant of the fluid. For this purpose it is necessary to develop a sensor whose size is compatible with microfluidic channel. The work, presented in this paper, studies effect of the parameters ... Read More
