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

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

Seeding Distribution in the Channel of a Cell Culture Vessel

J. Brcka [1], K. Kagawa [2], S. Ozaki [2], Y. Oshima [3], G. Zhang [4],
[1] Tokyo Electron U.S. Holdings, Inc., Austin, TX, USA
[2] Tokyo Electron, Technology Development Center, Chuo-ku, Kobe, Japan
[3] Tokyo Electron Europe LTD, Stem Cell Technology Centre, Stevenage, United Kingdom
[4] Clemson University, Rhodes Engineering Research Center, Clemson, SC, USA

Conventional cell culture (CC) techniques are advancing significantly with a trend towards a mass production. While plating density (number of cells per volume of culture medium) plays a critical role for some cell types, the initial distribution of these cells is affected by the actual ... En savoir plus

Permeability in Fragmented Materials and its Application to Underground Mining

S. Palma [1], R. Castro [1], A. Hekmat [1],
[1] Mining Engineering Department, Block Caving Laboratory, University of Chile, Santiago, Chile

The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of ... En savoir plus

Modeling of Porous Catalyst Pellets: Comparison of Diffusion Flux Models for Steam Methane Reforming

P. L. Mills [1], L. Olabanji [1], A. Nagaraj [1], A. Nanduri [1],
[1] Department of Chemical and Natural Gas Engineering, Texas A&M University - Kingsville, Kingsville, TX, USA

Introduction Steam reforming of natural gas has been the most common method for producing synthesis gas (CO + H2) for the production of H2, MeOH and NH3 for over half a century [1]. Production of H2 in the USA using steam methane reforming (SMR) is ca. 9 MM tons/yr. Global production ... En savoir plus

Design, Simulation, and Fabrication of Thermal Angular Accelerometers

H. Alrowais [1],
[1] School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA

This abstract introduces a sensor design for detecting angular acceleration in a single plane using thermal convection. The working principal of the device is based on probing temperature profile changes along a micro-torus caused by angular acceleration. By properly choosing the ... En savoir plus

Numerical Analysis on Plasmonic Nano-Cucumber Achieving Large EFs and Wide Tuneability of the Peak

A. Zare [1], E. Cutler [1], H. Cho [1],
[1] Center for Biomedical Engineering & Science, University of North Carolina - Charlotte, Charlotte, NC, USA

INTRODUCTION: Researchers in the biomedical field have recently become interested in the potential applications of plasomics. Surface plasmon resonance based on optical properties of metallic nanostructures can be used for detection of special biological targets. Gold nanostructures with ... En savoir plus

Statistical Modeling and Contact Analysis of RF MEMS Surface

J. Liu [1], V. B. Chalivendra [1], C. Goldsmith [2], W. Huang [1],
[1] Department of Mechanical Engineering, University of Massachusetts - Dartmouth, Dartmouth, MA, USA
[2] MEMtronics Corporation, Richardson, TX, USA

Radio frequency (RF) micro-electro mechanical system(MEMS) switch works in on/off modes controlled by electrostatic forces. In off mode, rough surfaces of electrodes come into a contact to shunt the RF signal. Surface contact area has been recognized as a key factor in RF MEMS ... En savoir plus
