We are continuing the development of a new primary standard for ac-dc difference that utilizes a superconducting resistive transition-edge device as the sensor...
To characterize the performance of solid-state voltage standards (Zener standards) the 1/f nature of Zener noise must be considered. At the Bureau International...
The National Institute of Standards and Technology (NIST) provides a service for measuring parameters associated with the step response of high-speed...
The effectiveness of an enterprise access control framework depends upon the integrity of the various components or the building blocks used in that framework...

Indoor air quality (IAQ) models are often used to predict airflows, contaminant concentrations and personal exposures for a given indoor environment. In order...
The impact of a distilled water droplet upon a heated wax surface was investigated experimentally using a high-speed digital camera at 1000 frames/s. Two...
A wide range of applications of cryogenic electronics to measurements and standards is described. Standards include those for voltage, capacitance and current...
NIST is using SNS Josephson junctions as the basis of quantum voltage metrology. Planar junction technology limits the voltage and bandwidth of these systems...

Thin films of the newly discovered superconductor MgB 2 show promise for a number of different electronic applications. In order to evaluate the suitability of...
We report on the development of a microwave power limiter based on high temperature superconductor technology. The power limiter takes the form of a 50 Ω...
We demonstrate how nonlinear effects in high temperature superconducting thin films can be quantified based on a current-dependent penetration depth λ(J). Using...

Temperature measurements have been made for natural-gas and heptane fires in a reduced-scale enclosure using a variety of bare-bead and aspirated thermocouples...
This paper begins with a historical review of flashing lights and physical measurement of flashing lights since the time the Blondel-Rey equation was developed...

A high-throughput combinatorial approach to edge delamination test is proposed to map the failure of adhesion as a function of both temperature and film...
ramics are hard, brittle, and chemically inert under most environments. They wear by abrasion and fracture. Since brittle fracture is very sensitive to stress...

Bonding, electric (hyper) polarizability; vibrational and magnetic properties of heterofullerene C 48B 12 are studied by first-principles calculations. Infrared...
Stable gases produced in SiH 4 and H 2-SiH 4, capacitively-coupled RF discharges, operated at typical device-production conditions, were investigated by...
The purpose of this paper is to define standard methods for effective and efficient image-based dimensional metrology for microlithography applications in the...
Wavelength calibration is essential to ensure channel stability and characterize optical components for wavelength division multiplexed optical fiber...
The growing and immediate threat of biological and chemical weapons has placed urgency on the development of chemical and biological warfare agent (CWA/BWA) and...
