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
Since 1994 a bank of four 10 pF oil-bath type fused-silica dielectric capacitors has been maintained in the NIST Impedance Calibration Laboratory for use as

Plans are described to experimentally demonstrate at JILA a possible phase measurement technique for use in LISA interferometry. This demonstration will include
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
This paper presents a new method that accurately determines the characteristic impedance of planar transmission lines printed on lossy dielectrics even when
This paper investigates the one-dimensional metal-insulator-semiconductor transmission line. It develops closed-form expressions for equivalent-circuit
