A Systematic Method for Producing Simulated Scattered Field Data from Known Structures

R. S. Ritter [1], M. A. Fiddy [2],
[1] Olivet Nazarene University, Bourbonnais, IL, USA
[2] University of North Carolina - Charlotte, Charlotte, NC, USA

One of the greatest challenges in developing algorithms for imaging from scattered fields is the lack of suitable scattered field data from known targets. It has proved quite difficult to acquire this data from measurements in the laboratory due the fact it can be costly, time ... En savoir plus

Finite Element Modeling of Eddy Current Probes for CANDU® Fuel Channel Inspection

M. S. Luloff [1], T. W. Krause [2], J. Morelli [1],
[1] Queen's University, Kingston, ON, Canada
[2] Royal Military College of Canada, Kingston, ON, Canada

CANDU® reactor pressure tubes (PT) contain D2O, which is used as a moderator. Surrounding the PTs are gas-filled Calandria Tubes (CT), which thermally isolate the PTs from the moderator surrounding the fuel channels. If the garter springs move apart, the PT will sag into the CT. Under ... En savoir plus

Control the Poly-Dispersed Droplet Breakup Mode in a Droplet-based Microfluidic Device by External Electric Field

Y. Li [1], K. Nandakumar [1], M. Jain [1],
[1] Cain Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA, USA

Droplet–based microfluidics has received special research attentions in last two decades due to its superior control over fluid flow as well as other unique advantages[1]. By introducing two immiscible fluids into microfluidic systems, the reagent fluid is encapsulated inside discrete ... En savoir plus

Simulation of a Buckled Cantilever Plate with Thermal Bimorph Actuators

A. Arevalo [1], D. Conchouso [1], D. Castro [1], M. Diaz [2], I. G. Foulds [3],
[1] CEMSE Division, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[2] Physical Sciences and Engineering Division, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[3] University of British Columbia, Vancouver, BC, Canada

INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... En savoir plus

Analysis of Magnetically-coupled Human Body Communications

S. A. Rocke [1], Daniel Ringis [1], Jeevan Persad [1],
[1] Department of Electrical and Computer Engineering, The University of the West Indies, St. Augustine Campus, Trinidad and Tobago

Human body communications (HBC) uses the human body as a transmission medium to connect sensors and actuators in, on or in close proximity to the human body. The HBC approach offers tremendous potential for the design and implementation of emerging personalized healthcare systems, as ... En savoir plus

Comparison of Magnetic Barkhausen Noise Tetrapole and Dipole Probe Designs

P. R. Underhill [1], T. W. Krause [1],
[1] Department of Physics, Royal Military College of Canada, Kingston, ON, Canada

COMSOL Multiphysics® software is used to understand the difference in behaviour of two Magnetic Barkhausen Noise (MBN) probes. The dipole probe has to be physically rotated to sample the angular distribution of the MBN. The tetrapole probe uses vector superposition to rotate the magnetic ... En savoir plus

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

Electron Drift in Xe Gas

T. J. Berger [1],
[1] Department of Physics, Applied Physics, and Astronomy, Rensselaer Polytechnic Institute, Troy, NY, USA

The XENON Dark Matter Experiment utilizes ultra-pure xenon (Xe) as a target for particle interaction in the effort to detect dark matter particles. To measure the purity of Xe, a gas purity monitor (GPM) is being developed which drifts electrons through Xe gas to detect impurities that ... En savoir plus

Skin Variations Impact on Non-Invasive Measurement of Blood Glucose with Interdigital Electrodes

J. Persad [1], S. Rocke [1],
[1] Department of Electrical and Computer Engineering, University of the West Indies, St. Augustine, Trinidad and Tobago

This work aims to investigate the behaviour of a simple interdigital sensor structure for glucose monitoring in response to distortions in the skin-topology and differences in skin undulation during use. The study then extends to consider a flexible sensor structure which is better able ... En savoir plus

Simulation of the Impedance Response of Thin Films as a Function of Film Conductivity and Thickness

Y. Jin [1], S. Kumar [1], R. A. Gerhardt [1],
[1] School of Materials Science and Engineering, Georgia Institute of Technology, Atlanta, GA, USA

Introduction The electrical properties of materials are important in many different applications. In microelectronics for example, films must perform as insulators, semiconductor or as conducting layers. In recent years, scanning probe methods are being extended to the nanometre scale ...
