3D Optical Human Eye Model Based on COMSOL Multiphysics® to Provide a Test Bench for Laser Surgery

S. Regal [1], R. Delattre [1], M. Ramuz [1],
[1] Department of Flexible Electronics, Ecole Nationale Supérieure des Mines, Centre Microélectronique de Provence CMP-EMSE, MOC, Gardanne, France

We present here the development of an optical human eye model – based on Ray Optics module in order to reproduce the eye optical properties. Current simulations in literature do not fully cover the light propagation inside all parts of the eye by taking into account the absorption but ... 詳細を見る

Unbalanced Torque Signal Generation for Kinetic Energy Harvesters

L. Kurmann [1],
[1] University of Freiburg, IMTEK, Freiburg, Germany

The problem of an unbalanced mechanical torque signal generation using nonpolar repulsion techniques is studied. To achieve such an unbalanced torque, several stator and rotor geometries, consisting of nonlinear permanent magnet spring batteries are investigated. It can be shown that an ... 詳細を見る

Design of a Mechanical Resonant Station to Free Jammed Micro-Mechanisms

L. Spicci [1],
[1] Everywave srl, Italy

Some types of mechanical devices, such as molds, but not only, include a large number of micro-mechanisms, valves, channels, vents, or other devices subject to deterioration or malfunctioning, frequently caused by unwelcome phenomena such as incrustations, fillings, or reciprocal bonding ... 詳細を見る

Modeling the Dynamic Viscous and Thermal Dissipation Mechanisms in a Fibrous Porous Material

B.P. Semeniuk [1], P. Göransson [1],
[1] KTH Royal Institute of Technology, Marcus Wallenberg Laboratory for Sound and Vibration Research, Stockholm, Sweden

The main mechanisms of acoustic attenuation in a bundle of fibres typical of lightweight fibrous porous materials are the dynamic viscous drag forces on the surface of the fibres, and the thermal heat transfer between the solid fibres and the surrounding fluid. Microstructure models ... 詳細を見る

Modeling Alpha-Galactosides Behavior during Cowpea Soaking-Cooking for Nutritional Optimization

A. Briffaz [1], F. Coffigniez [1], C. Mestres [1], P. Bohuon [2],
[1] CIRAD, France
[2] Montpellier SupAgro, France

Cowpea seed is a pulse which is very rich in vital micronutrients but also in anti-nutritional factors such as α-galactosides (verbascose, stachyose and raffinose) that can cause digestive disorders after consumption. The objective of this work was to identify the transport and ... 詳細を見る

The Relevant Scale for Mechanical Modeling in Additive Manufacturing Technologies

S. Guessasma [1], S. Belhabib [2], H. Nouri [3],
[1] INRA, Nantes, France
[2] 3 LUNAM Université Nantes Angers Le Mans, CNRS, GEPEA, UMR 6144, IUT de Nantes, Carquefou, France
[3] 3IMT Lille Douai, Institut Mines-Télécom, Douai, France

Additive manufacturing technologies do not share the same rendering depending on the type of material discontinuities induced by material processing. This study aims at revealing the role of microstructural defects as driving factors for the mechanical performance of polymeric parts ... 詳細を見る

When Precise Numerical Predictions Come to the Rescue of Liquid Lubrication

J. D. Wheeler [1], V. Bruyere [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Whereas some bearings designed in the 19th century are still working properly nowadays, some others which were recently designed encountered premature failures. Tribological applications, such as journal bearings or rolling element bearings, are generally ruled by complicated ... 詳細を見る

Simulation of the Electrical Properties of Conductive ITO Thin Films by Finite Element Analysis

R. A. Gerhardt [1], N. Xia [1], Y. Jin [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA

Finite element analysis (FEA) can be used to study the electrical properties of conductive ITO thin films. Previous studies have been done on insulating thin films deposited on conductive substrates [1,2]. It was found that changes of electrode size and film thicknesses can cause huge ... 詳細を見る

Simulation of an Ethane Steam Cracking Reactor for Ethane-Propane Mixtures

R. Martinez [1], J. A. Galán [2], Y. Amaya [1], H. S. Arenas [1]
[1] Universidad Industrial de Santander, Bucaramanga, Santander, Colombia
[2] Empresa Colombiana de Petróleos, Barrancabermeja, Santander, Colombia

This study allows to establish the possibility to carry out the pyrolysis of mixtures of ethane-propane in an existing steam-cracking reactor (SCR) originally designed for ethane pyrolysis. The final goal of this study was to minimize new investments, e.g. a purchase of new equipment, ... 詳細を見る

Simulating 200 kHz AC Tumor-Killing Fields with COMSOL Multiphysics®

K. W. Carlson [1], N. Paudel [2], S. Dokos [3], J. A. Tuszynski [4],
[1] Beth Israel Deaconess Medical Center - Harvard Medical School, Boston, MA, USA

[3] University of New South Wales, Sydney, NSW, Australia
[4] University of Alberta, Edmonton, AB, Canada

Alternating 200 kHz electric fields ~2 V/cm (Tumor Treating Fields, ‘TTFields’) kill cancer cells by disrupting the delicate orchestration of chromosome spindle formation, but the exact mechanism of action is unknown. The likely suspects are polarized intracellular molecules such as ... 詳細を見る
