On-Board Signal Integrity for GPS

September 21, 2010
Author(s)
Marc A. Weiss, Pradipta Shome, Ron Beard
The elements of a space-based integrity approach are to monitor the signals on-board the satellite, such that signal performance can be maintained well within desired integrity limits. These elements include 1) a system for monitoring multiple atomic

CMSD: A Model Supporting Manufacturing and Simulation Application Integration

September 20, 2010
Author(s)
Frank H. Riddick, Yung-Tsun T. Lee
Standard representations for key manufacturing entities could help reduce the costs associated with simulation model construction and data exchange between simulation and other software applications. This change would make the use of simulation technology

lSPR Study of DNA Wrapped Single Wall Carbon Nanotube (ssDNA-SWCNT) Adsorption on a Model Biological (Collagen) Substrate

September 20, 2010
Author(s)
Jung Jin Park, Jeffrey Fagan, JiYeon Huh, Kalman D. Migler, Alamgir Karim, Dharmaraj Raghavan
The kinetics of single stranded-DNA dispersed single wall carbon nanotubes (SWCNTs) adsorption onto an immobilized collagen layer in a microfluidic channel was probed using surface plasmon resonance (SPR) imaging. The adsorption was measured for a range of

Reliability Issues of SiC MOSFETs: A Technology for High Temperature Environments

September 20, 2010
Author(s)
Liangchun (. Yu, Greg Dunne, Kevin Matocha, Kin P. Cheung, John S. Suehle, Kuang Sheng
The wide-bandgap nature of silicon carbide (SiC) makes it an excellent candidate for applications where high temperature is required. The MOS-controlled power devices are the most favorable structure, however, it is widely believed that silicon oxide on

Advances in Modeling of Scanning Charged-Particle-Microscopy Images

September 19, 2010
Author(s)
Petr Cizmar, Andras Vladar, Michael T. Postek
Modeling scanning electron microscope (SEM) and scanning ion microscope images has recently become necessary, because of its ability to provide repeatable images with a priori determined parameters. Modeled artificial images have been used in evaluation of

Predicting Microstructure Development During Casting of Drug Eluting Coatings

September 19, 2010
Author(s)
David M. Saylor, Jonathan E. Guyer, Daniel Wheeler, James A. Warren
We have devised a novel diffuse interface formulation to model the development of chem- ical and physical inhomogeneities, i.e. microstructure, during the process of casting drug eluting coatings. These inhomogeneities, which depend on the coating

Current induced torques in the presence of spin-orbit coupling

September 17, 2010
Author(s)
Paul M. Haney, Mark D. Stiles
In systems with strong spin-orbit coupling, the relationship between spin-transfer torque and the divergence of the spin current is generalized to a relation between spin transfer torques, total angular momentum current, and mechanical torques. In
