Simulation of a Magnetic Induction Method for Determining Passive Electrical Property Changes of Human Trunk Due to Vital Activities
H. Mahdavi[1], J. Rosell Ferrer[1]
[1]Universitat Politècnica de Catalunya, Barcelona, Spain
The human body consists of many different types of tissues each with specific passive electrical properties. Vital activities lead to a characteristic change of these properties and geometrical changes. Magnetic induction is a non-contact method which can be used to determine these changes. The method is based on the creation of a primary magnetic field that will produce eddy currents in the ...

Electrokinetic transport of fluids has been investigated both experimentally and numerically due to its various applications in microfluidic devices [1-5]. These devices offer the advantage of transporting fluids or particles to specific locations without the aid of mechanical components. The device by Green et al consists of a symmetric arrangement of CPE subjected to an AC potential [6-8]. The ...
Simulation of a Plastic Bottles Solar Collector

In the Andean region of Southern Peru, poverty and climate are extreme: at 4000mt asl, insolation is among the highest in the world but the temperature varies more than 30 degrees between day and night. At the community of Livitaca (Cuzco), the association “Ingegneria Senza Frontiere” is working on a project of bioclimatic architecture. In this context, it is devised a low cost drainback solar ...

Thermally conducting but electrically insulating materials are needed for heat-sink LED lighting applications. We report on a cost effective and innovative method based on creating core-shell nanoparticles in polymer with aluminum (Al) nanoparticles as the high thermal conductivity core and ultrathin aluminum oxide (Al?O?) as a capping shell. The solid oxide shell around the Al core prevents ...
Simulation of Gravitational Instability During CO2 Absorption in a NaHCO3/Na2CO3 Solution

[1]Université Libre de Bruxelles (ULB), Transfers, Interfaces and Processes (TIPs), Brussels, Belgium
This work deals with the modeling and the numerical simulation of the CO2 absorption, coupled with a chemical reaction, in an initially quiescent aqueous solution of sodium carbonate (Na2CO3) and bicarbonate (NaHCO3), inside a Hele-Shaw cell. In our Hele-Shaw cell, the liquid fills partially the gap between two parallel transparent Plexiglas plates. CO2 is forced to flow above the liquid in the ...

SAFARI is a far-infrared imaging spectrometer for the Japanese satellite observatory SPICA. SAFARI covers the wavelength range 34—210 μm (1.4—8.8 THz) using Transition-Edge-Sensor (TES) bolometers. We have built a test facility to qualify and characterize the SAFARI focal plane units using cryogenic optical calibration sources. To support this work we have used COMSOL Multiphysics® to model the ...
Numerical Modelling of the Plasma Discharge During Electron Beam Welding (EBW) - new

[2]Institute of Electronics of Bulgarian Academy of Sciences, Sofia, Bulgaria
This work describes a model for plasma formation in the keyhole and above the EBW zone. The parameters of the plasma are closely connected to the characteristics of the thermal action of the electron beam on the welded metal, which allows operational control and study of EBW. The ionization intensity of the vapour due to beam electrons and high-energy secondary and backscattered electrons is ...
Integrated Ion Optics Design - new

Introduction: This study aims the optimization and sensitivity analysis of an existing device. A Secondary Ion Mass Spectrometer (SIMS) device is to be equipped with a high power laser in order to increase sputtering speed. The modified device must be capable of handling the increased level of contamination and energy spread of sample ions. Use of COMSOL Multiphysics® software: Transmission ...

The radiation force effects on the surface displacement can be calculated by solving the Navier-Stokes equation with appropriated boundary conditions. The surface deformation can be described by the radiation pressure as well as those forces due to gravity and surface tension. We used the photomechanical mirror (PM) method to measure the time-evolution of the nanometer deformation generated on ...
