Understanding the Origin of Uncertainty in Thermometer Calibration

Jonathan Pearce
National Physical Laboratory
UK

Thermometers have widespread application and like any measurement device, they must be calibrated. Many do this with the International Temperature Scale of 1990 (ITS-90), which is a platinum resistance thermometer that calibrates using a fixed point cell, which is a container with a well running through its center for insertion of the thermometer. The container has a material of 99.9999% purity. ...

Easy and Accurate Measurement of Blood Viscosity

Microvisk Technologies, North Wales, UK

Microvisk Technologies develops and manufactures devices for measuring blood viscosity using the power of Micro Electronic Mechanical Systems (MEMS) and a radical new technique stemming from futuristic research on microtechnology. Older hand-held devices on the market work by inducing a chemical reaction that is picked up by electrodes coated with componds. The MEMS-based micro-cantilever ...

Capacitively Coupled Plasma Analysis

Luke T. Gritter, Sergei Yushanov, Jeffrey S. Crompton, and Kyle C. Koppenhoefer
AltaSim Technologies
Columbus, OH

AltaSim Technologies provides engineering consulting services involving advanced multiphysics modeling such as capacitively coupled plasma (CCP). Plasma etching and deposition of thin films, critical processes in the manufacture of advanced microelectronic devices, commonly utilize CCP, in which the plasma is initiated and sustained by an oscillating electric field between two or more ...

Pushing the Limits of Chip Density

Derek Bassett and Michael Carcasi
Tokyo Electron America
Austin, TX

Chip manufacturers have been adhering to Moore’s law, a law stating that the number of transistors that can be economically placed on an integrated circuit doubles every year, since 1965. As the number of transistors increases, however, the process of manufacturing integrated circuit, called photolithography, becomes more difficult. Each device requires approximately 200 cleaning and ...

How Reclosers Ensure a Steady Supply of Power: It’s All in the Magnet

O. Craciun, and colleagues
ABB AG
Ladenburgh, Germany

When a tree branch touches overhead cables and causes a momentary short circuit, your lights may flicker. A device called a recloser ensures that power to your home is not cut off for a longer period. ABB AG, a leading manufacturer in power technology, is working towards designing a more reliable recloser. One objective in this design process was to optimize the size of the permanent magnet ...

Simulation-Based Design of New Implantable Hearing Device

Patrik Kennes
Cochlear Technology Centre, Mechelen, Belgium

Cochlear Technology Centre Europe (CTCE) develops new technology for hearing implants. Their current work is with a new type of hearing implant, a Direct Acoustic Cochlear Implant called CodacsTM. This product imposes structural, pressure waves directly to the cochlea, stimulating it this way, as opposed to amplifying sound. Using COMSOL Multiphysics, the team was able to test the many ...

Cluster Simulation of Refrigeration Systems

Stephen Codyer & Mehdi Raessi
Department of Mechanical Engineering
UMass Dartmouth
Dartmouth, MA

Jessica Currie & Vladimir GoldsteinSunwell Technologies, Inc., Woodbridge
ON, Canada

Sunwell Technologies Inc. produces and distributes the slurry ice (Deepchill™) that is an environmentally-friendly way to refrigerate foods and other items in trucks and the like. They commissioned the Computational Multiphase Flows group at the University of Massachusetts, Dartmouth (UMass Dartmouth) to provide simulation support to the experimental investigations performed by Sunwell. Known ...

Multiphysics Simulations Enable Development of Fast, Cheap MEMS-Based Bacteria Detector

Yale University
New Haven, CT

Professor Mark Reed and his team at Yale University are using COMSOL Multiphysics to develop a MEMS-based solution for detecting bacteria in blood. Called the ?Screen, it will provide analyses speedily, accurately, and cost-effectively. Such a device would greatly help the food industry in improving meat quality and reducing the risk for infections. Current methods take too long for most food ...

Multiphysics Simulations Help Track Underground Fluid Movements

A. Haas, H. Mahardika, M. Karaoulis, and A. Revil
Colorado School of Mines, USA

Combining acoustic and electromagnetic analyses helps scientists to more efficiently measure and survey subterranean regions. Acoustic waves can travel long distances, but have limitations when it comes to providing details about formation properties, and cannot be used to identify the liquids flowing through them. Electromagnetic waves do not propagate as far as acoustic waves, but can identify ...
