Design and Simulation of A MEMS Based Horseshoe Shaped Low Current Lorentz Deformable Mirror (LCL-DM)

B. Park [1], T. Chen [1], C. Shafai [1],
[1] Department of Electrical and Computer Engineering, University of Manitoba, Winnipeg, MB, Canada

This poster presents the design and analysis of a novel horseshoe shaped MEMS actuator for adaptive optics. The actuation mechanism is Lorentz force enabling low current (below 10 mA) operation. The actuator combined with an overlying aluminum coated SU-8 soft polymer membrane for the ... En savoir plus

Innovation of Combustion Particle Control Technologies Assisted by Numerical Modeling

D. Rubinetti [1],
[1] Institute of Biomass and Resource Efficiency, University of Applied Sciences and Arts Northwestern Switzerland, Windisch, Switzerland

Worldwide efforts to promote the use of renewable energies include combustion-based technologies that produce substantial amounts of pollutants. In order to control the environmental impact a proper treatment of exhaust gases is required. This study describes the development of a ... En savoir plus

Microstimulation in The Brain: Does Microdialysis Inuence the Activated Volume of Tissue?

D. Krapohl[1][3], S. Loeffler[2], A. Moser[2], and U.G.Hofmann[1]

[1]Institute for Signalprocessing, University of Luebeck, Lübeck, Germany
[2]Institute for Neurology, University of Luebeck, Lübeck, Germany
[3]Department of Information Technology and Media, Mid Sweden University, Sundsvall, Sweden

Deep Brain Stimulation (DBS) has been established as an effective treatment for Parkinson's disease and other movement disorders. The stimulation is currently administered using tetrode-macroelectrodes that target the Subthalamic Nucleus (STN). This often leads to side effects which bias ... En savoir plus

Design and Simulation of a Microelectromechanical Double-Ended Tuning Fork Strain Gauge

H. H. Zhang [1], A. Bardakas [1], W. D. Leon-Salas [1],
[1] School of Engineering Technology, Purdue University, West Lafayette, IN, USA

Strain gauges have been extensively used for detecting strain in various applications. Double-ended tuning fork (DETF) strain gages present better performance characteristics than standard foil gauges, including higher sensitivity, smaller size and higher resolution. This study focuses ... En savoir plus

Towards Multiscale Models for Bioimpedance of Human Skin with COMSOL Multiphysics

Karl Erik Birgersson [1],
[1] National University of Singapore, Singapore

Mechanistic mathematical modeling for electrical impedance spectroscopy (EIS) of human skin involves not only the equation of change for the alternating current from and to the electrodes of the EIS probe but also the spatial resolution of the various skin layers and their material ...

Experimental Observation and Numerical Prediction of Induction Heating in a Graphite Test Article

T.A. Jankowski[1], D.P. Johnson[1], J.D. Jurney[1], J.E. Freer[1], L.M. Dougherty[1], and S.A. Stout[1]

[1]Los Alamos National Laboratory, Los Alamos, New Mexico, USA

The induction heating coils used in the plutonium casting furnaces at the Los Alamos National Laboratory are studied here. A cylindrical graphite test article has been built, instrumented with thermocouples, and heated in the induction coil that is normally used to preheat the molds ... En savoir plus

Analysis of Forces acting on Superparamagnetic beads in fluid medium in Gradient Magnetic Fields

U. Veeramachaneni[1], and R.L. Carroll[1]

[1]Department of Chemistry, West Virginia University, Morgantown, West Virginia, USA

Superparamagnetic micro beads offer some attractive applications in biological and biomedical fields. Some of the important applications include manipulation and separation of cells, isolation of specific cells, active drug delivery, magnetic cell separation, separation of proteins, and ...

Dynamic Study of Field and Current Distribution in Multifilamentary YBCO Thin Films

F. Grilli[1], A. Lucarelli[2], G. Lüpke[2], T. Haugan[3], and P. Barnes[3]

[1]Ecole Polytechnique de Montréal, Montréal, QC, Canada
[2]College of William and Mary, Williamsburg, VA, USA
[3]Air Force Research Laboratory

We have developed a model for computing current and field distributions in multifilamentary superconducting thin films subjected to the simultaneous effects of transport ac current and applied dc field perpendicular to the sample. The model is implemented in COMSOL’s PDE module (general ... En savoir plus

Influence of a Porous Corrosion Product Layer on the Corrosion Phenomenon of Carbon Steel Pipelines

M. Mohamed-Saïd [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Assessing the severity of the internal corrosion of structures is of paramount importance in the oil & gas industry. Modelling and simulation of this process proved to be key techniques to understand its mechanism and the main factors influencing its severity [1-4]. Considerable ... En savoir plus

Impact of Electro-Convection (EC) on Heat Transfer in Liquid-Filled Containers

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corporation, Hauppauge, NY, USA

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage ... En savoir plus
