A Comparison of Mass Reduction Methods for Silicon-on-Oxide (SOI)-based Micromirrors

H. J. Hall [1], L. A. Starman [1],
[1] Sensors Directorate, Air Force Research Laboratory, Wright-Patterson AFB, OH, USA

Beam steering and adaptive optics micromirror applications commonly demand optically flat surfaces with minimal mass. When reflective coatings (usually metallic Au or Al) are applied to micromirror surfaces in order to meet optical reflectivity requirements the resulting film stress ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

Seeding Distribution in the Channel of a Cell Culture Vessel

[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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen
