This paper gives results of the cooling performance of a double-inlet pulse tube refrigerator using various redenerators. The same pulse tube was used for all...
Two novel acoustic resonators have been developed, one for measuring the viscosity and a second for measuring the Prandtl number of gases. For viscosity...
Our laboratory has developed an automated apparatus for measuring the sound speed in hazardous gases such as those used in processing semiconductors. The sound...

Because atomic force microscopes (AFMs) are capable of generating three dimensional images with nanometer level resolution, these instruments are being...
In scanned probe microscopy, it is necessary to know the tip's geometry in order to correct image distortions due to its finite size. Heretofore, methods have...
Dimensional measurements of importance to microlithography include feature sizes and feature placement on photomasks and wafers, overlay eccentricities, defect...
We developed a noninvasive x-ray technique to monitor the solidification of single-crystal castings. X-ray energies in the 150 keV to 320 keV range have...
This investigation compared the performance of R22 to the performance of R290 and that of flammable zeotropic mixtures, R32/290 and R32/152a. The tests were...

The stringent critical dimension (CD) control requirements in cutting edge device facilities have placed significant demands on metrologists and upon the tools...
A new method is presented to determine the time-base errors of sampling instruments. The method does not require a model for the time-base error and, thus...
Accurate measurement of high voltage (hv) impulse waveforms is of critical importance in the testing of hv apparatus and for fundamental insulation studies...
The adhesive strength of a composite resin to dentin is greatly influenced by the degree of cure of the bonding agent. Flouorescent probes have often been used...

The current generation of giant magnetoresistance (GMR) spin valves exhibits performance characteristics which are not quite as good as desired for ultrahigh...
The long term stability of multilayer materials composed of nonreactive, immiscible materials is related to the equilibrium shapes of the individual grains...

Software testing is hard, expensive, and uncertain. Many protocols have been suggested, especially in the area of conformance verification. In order to compare...
The Building and Fire Research Laboratory at the National Institute of Standards and Technology, under the sponsorship of the United States Fire Administration...
Efficient data combination over wide-area networks is hard as wide-area networks have large variations in available network bandwidth. In this paper, we examine...
Multimedia desktop conferencing systems are gaining momentum and increasingly becoming a reality. In these systems, besides using audio, video and multi-user...
Our 30th Joint Meeting provides an opportunity to reflect on our work and accomplishments and establish our view for the future of our U.S./Japan Panel on Wind...
