In order to improve the capacitance calibration services at the National Institute of Standards and Technology, we need to determine the frequency dependence of
Grain is an essential source of the world's human and animal food supply. The production value of major grains in the United States is approximately $3.3
Waste loads require test representations with artifacts for actual load which have not achieved researchers' consensus for wide recognition. Disparate practices
This paper presents entropy generation analyses for the evaporator, compressor, gas cooler, expansion device and liquid-line suction-line heat exchanger for a
An experimental investigation was implemented to determine the capacity degradation due to non-uniform refrigerant and air flow distributions, and to assess the
The strengthening of epoxy with milled glass fibers allows full strength development of #2 glass FRP bars in 200 mm or half a concrete masonry unit length. This

Visible photoluminescence from Si (100) surfaces irradiated by highly-charged ions has recently been reported. 1 This discovery has potential applications in
An algorithmic model of bi-directional reflectance distribution function (BRDF) based on the ray optics approximation and microfacet model of randomly rough
agents provide a means to integrate various manufacturing software applications. The agents are typically executed in a computer-based collaborative environment

We describe a research project on resolving semantic differences for multi-agent systems (MAS) in electronic commerce. The approach can be characterized as
Small machine shops typically do not have the resources to develop custom simulations of their operations or data translators to import their data from other
The contribution of software to the uncertainty of measurements is an important but often overlooked aspect of uncertainty evaluations. In coordinate metrology

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 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
