Friday, September 15, 2006 Third Generation Flywheels For High Power Electricity Storage
ABSTRACT:
First generation flywheels of bulk material such as steel can mass tens of tons, but have low en-ergy storage density. Second generation flywheels of composite materials have higher energy storage density but limited...
Friday, September 15, 2006 THE MAGTUBE LOW COST MAGLEV TRANSPORTATION SYSTEM
ABSTRACT:
LaunchPoint Technologies has constructed a prototype vehicle to demonstrate the feasibility of low cost maglev transportation systems. When maglev technology was first proposed, nearly 100 years ago, it was only...
Monday, October 24, 2005 Elimination of Adverse Leakage Flow in a Miniature Pediatric Centrifugal Blood Pump by Computational Fluid Dynamics-Based Design Optimization
Abstract
We investigated a miniature magnetically levitated centrifugal blood pump intended to deliver 0.3–1.5 l/min of support to neonates and infants. The back clearance gap between the housing and large volume of the rotor,...
Wednesday, July 20, 2005 Design Optimization of Blood Shearing Instrument by Computational Fluid Dynamics
Abstract
Rational design of blood-wetted devices requires a careful consideration of shear-induced trauma and activation of blood elements. Critical levels of shear exposure may be established in vitro through the use of devices...
Wednesday, October 01, 2003 MEMS Resonators That Are Robust to Process-Induced Feature Width Variations
Abstract
A stability analysis and design method for MEMS resonators is presented. The frequency characteristics of a laterally vibrating resonator are analyzed. With the fabrication error on the sidewall of the structure being...
