In this paper we investigate the broadband microwave properties of high-impedance probes designed for on-wafer waveform measurements. We show that the standard
The National Institute of Standards and Technology operates and maintains piston gage pressure standards from 7 kPa to 280 Mpa, a span of over 4 decades in

This paper describes a method of generating models for nonlinear devices and circuits, based upon measurements of traveling-wave voltages at a periodic large
Insulating gas mixtures containing SF 6 have been promoted to serve as replacements for pure SF 6 in order to reduce SF 6 atmospheric emission. It has been

Hydrogen bonding of water (H 2O) is certain to introduce an effect of the molecular energy to the heat capacity. Due to the presence of the strong hydrogen
We present results for uncertainties in noise-parameter measurements, obtained using a Monte Carlo simulation of the measurements. Sets of data were generated

The structural and optical properties of indium gallium nitride (InxGa1-xN) films with 0.04
The Versailles Project on Advanced Materials and Standards (VAMAS) was created in 1982 to support trade through international collaboration in pre-standards
An Al-W-silica integrated circuit interconnect sample was thinned to several micro υ and scanned across a 200 nm focal spot of a Fresnel zone plate operating at
Until recently, the primary calibration of accelerometers at NIST over a frequency range of 50 Hz to 5 kHz utilized three different shakers with separate
Faceting in a polyhedral rutile particle was modeled from transmission electron microscopy images. A relatively new double-tilt, rotate transmission electron
A predictive method for estimating the zij parameter in the mixture model of Lemmon and Jacobsen [Int. J. Thermophysics 20:1629 (1999)] has been developed. Data
As durability issues become increasingly prominent in concrete design, the need to predict the transport properties of a given concrete mixture becomes critical

rylic-melamine coatings are used extensively for automobile topcoat/base coat systems. However, these materials undergo hydrolysis when they are exposed to
A variety of alternate calibration schemes which approximate the ITS-90 are possible when using high-purity noble metals. The high purity of the sensor
NIST started working with industry and the Institute of Electrical Engineers (IEEE) in the mid 90''s to develop a standardized interface to network smart
Recent technological advances in machine tool design and construction (most notably reliable high speed/power spindles and high velocity/acceleration drives)
This is a report to the committee regarding reflection measurements that impact the current draft standard. Diffuse reflectance measurements are compared to
The 6-Degree of Freedom Tri Stage Micro Positioner (6DFTSMP) can generate high accuracy, small displacement, and high-resolution motions. The moving platform of
In order for web specifications to permit full interoperability and access to all, it is important that the quality of implementation be given as much attention
We demonstrate that local oxidation of silicon nitride films deposited on conductive substrates with a conductive-probe atomic force microscope (AFM) is a very
There are three areas to consider when planning to wire bond to new chips having copper bond pads and low dielectric-constant polymers imbedded beneath them (Cu
Validation of computational fluid dynamics (CFD) predictions for spray combustion application has been a challenging task due to difficulties in both modeling
