Thermal component models are developed for multi-chip IGBT power electronic modules (PEM) and associated high-power converter heatsinks. The models are
To detect a fault in software, a test case execution must be chosen so intermediate errors propagate to the output. We describe two modeling methods for

Negative bias temperature instability (NBTI) and Positive bias temperature instability (PBTI) of p-MOSFETs with 2.4 nm thick oxide films were studied. The Δ}Vth
The defect generation rate (P g) during constant voltage stress is investigated by using short-time voltage pulses over large fluence range. It is found that P
Linux is a version of the Unix operating system distributed according to the open source model. Programmers are free to adapt the source code for their purposes
Today, much of our information-intensive work is carried out at desktop computer workstations; however, increasingly people work and live on the move. Very soon
The Text REtrieval Conference (TREC) has been running for 11 years now, with 93 participants in the last round of evaluation. This paper chronicles the changes
Superconformal electrodeposition of copper is explained by the recently developed curvature enhanced accelerator coverage (CEAC) mechanism. The model stipulates

Surface acoustic wave (SAW) spectroscopy is a nondestructive way to determine the properties of thin films. Plane-wave SAWs are generated by a line-focused
The development and evaluation of an optical system for a new spectral directional emittance facility at NIST is reported. The imaging quality and signal
The National Institute of Standards and Technology (NIST) maintains a wide range of scientific and technical data resources, including free online data systems
Several classes of transmembrane protein ion channels function in vivo as sensitive and selective detection elements for analytes. Recent studies on single
The National Institute of Standards and Technology is building an advanced-design guarded hot plate apparatus of advanced design to provide very accurate
Thermal conductivity measurements of four thermal insulation reference materials are presented. The measurements were obtained from an international study of
Adhesion at the fiber-matrix interface of composite is often related to a combination of factors such as mechanical interlocking, physico-chemical interactions
In order to make an unmanned vehicle drive truly autonomously, many different software components are needed. Each of these components is tasked with providing
It was recently shown that individual molecules of single-stranded DNA can be forced through a nanoscale pore by an electric field. We demonstrate signal
