An Examination of Wall Shear Stresses in Curved Arterial Vessels Using Bioresorbable Stents

D. W. Pepper [1], S. Pirbastami [1],
[1] University of Nevada - Las Vegas, Las Vegas, NV, USA

Bioresorbable stents are providing temporary mechanical support to keep a narrowed or blocked coronary artery open and restore the blood flow and will be gradually degraded and resorbed after the healing and remodeling of arterial wall. This new generation of stents has lower rates of ... En savoir plus

Design and Simulation of a Piezoelectric Actuated Valveless Micropump

J. J. Rojas [1], J. E. Morales [2],
[1] School of Electromechanical Engineering, Instituto Tecnológico de Costa Rica, Cartago, Costa Rica
[2] School of Electronic Engineering, Instituto Tecnológico de Costa Rica, Cartago, Costa Rica

Microfluidics is a multidisciplinary field, basically it designs systems to handle small volumes of fluids. Most applications require a pumping action in order to move the fluid trough the system. For most of them a micro scale active pump is highly desirable. A piezoelectric micropump ... En savoir plus

[4] University of Parma - Department of Information Engineering, Parma, Italy

We describe the thermal modeling of a crate hosting boards with Associative Memories (AM) designed for the Fast Tracker Trigger (FTK) system of the ATLAS detector at the CERN Large Hadron Collider. FTK is a highly paralleled hardware system designed to provide global tracks reconstructed ... En savoir plus

Multiphysics Modelling of a Microwave Furnace for Efficient Solar Silicon Production

N. Rezaii [1], J. P. Mai [1],
[1] JPM Silicon GmbH, Braunschweig, Germany

The JPM Silicon GmbH presents a novel method for the production of solar grade silicon in the microwave oven. This method can specially reduce the energy costs and increase the efficiency of the process. A numerical model is developed which depicts the physical, chemical and ... En savoir plus

Time Domain Construction of Acoustic Scattering by Elastic Targets Through Finite Element Analysis

A. Gunderson [1], B. Simon [1], A. Bonomo [1], M. Isakson [1],
[1] Applied Research Laboratories, University of Texas - Austin, Austin, TX, USA

Finite element models for acoustic scattering from three dimensional underwater elastic objects, calculated in the frequency domain, are transformed to the time domain through Fourier synthesis using COMSOL Multiphysics®. The time domain mirrors the way in which experimental scattering ... En savoir plus

Topology Optimization of Thermal Heat Sinks

[1] Technical University of Denmark, Roskilde, Denmark
[2] Technical University of Denmark, Kgs. Lynby, Denmark

Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in [3] for forced convective heat transfer and in [4] for natural convection ... En savoir plus

Development of a Thermal Model Using COMSOL Multiphysics® Software

A. Oukaira [1], A. Lakhssassi [1],
[1] Department of Computer Science, Université du Québec en Outaouais à Hull, Gatineau, QC, Canada

The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map ... En savoir plus

Acoustic-Structure Interaction Simulation of a Differential Phase Sensor

J. H. Lee[1]
[1]Department of Mechanical Engineering, American University of Sharjah, Sharjah, UAE

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... En savoir plus
