High-voltage thermal converters (HVTCs) are used as standards of ac-dc difference and for the measurement and calibration of ac voltage up to 1000 V and 100 kHz
The National Institute of Standards and Technology (NIST) offers resistance Measurement Assurance Program (MAP) transfers at the 1 ohm} and 10 kohm} levels, to
Spectroradiometers and tristimulus colorimeters are used in display measurements to measure color in one of several color space coordinate systems. How well

High precision voltage calibrations are now regularly performed in industrial calibration laboratories with Josephson array voltage standard systems. A full
Although the need to transition new technology to improve the process of developing quality software products is well understood, the computer software industry
A spectrophotometer system for spectral characterization of materials in the infrared has been built around a bench-top Fourier transform (FTIR) instrument. Its
Biometric-based identification and verification systems are poised to become a key technology, with applications including controlling access to buildings and
Recently the authors introduced a length scale for effectively collapsing the near field centerline velocity and mass fraction of constant and variable density
The broadcast news benchmark tests have potential as a source of ideas for improving continuous speech recognition systems. This paper presents a data analysis
The BEES (Building for Environmental and Economic Sustainability) software implements a rational, systematic technique for balancing the environmental and
We evaluated a near-chip-scale package, that utilizes the flip-chip, plastic-ball-grid-array technology with microvias. The microvias were photolithographically

A set of wafer probeable diode noise source transfer standards are characterized using on-wafer noise temperature methods developed recently at the National
Several lumped-element calibrations have been proposed for four-sampler vector network analyzers. This paper offers the first assessment of their accuracy in
An ultrasonic transit time flowmeter was tested over Reynolds numbers from 1000 to 100,000 in a calibration facility that generates gas flows with controlled
A field investigation of tape-bonded seams of EPDM (ethylene propylene diene terpolymer) roof membranes is described. Since the early 1990s the use of tape
Progress in the development of a cryogenic catheter to treat heart arrhythmia is discussed. This system uses a mixed-gas Joule-Thomson refrigerator to cool the
The U.S. Federal Government has a strong role in metrology R&D in the U.S because of its importance to the nation's economy and the Constitutional authority
