Stress mapping techniques by use of an acoustic microscope make use of shear acoustic modes traveling back and forth across the specimen, generated by use of
Dependence of contact resistance on current has been measured for a large number of ohmic contacts to quantized Hall resistors under quantum Hall effect
The NIST calibration service that provides electric energy traceability for the U.S. utility industry is described. Electronic watthour meters, submitted for
The hydrophobic hydration in a series of hydrocarbons is probed using molecular dynamics simulations. The solutes considered range from methane to octane

Chemical shifts result from changes in electron binding energies with the chemical environment of atoms. In x-ray spectra, chemical shifts lead to changes in x
Glassy (amorphous) metals have some unique properties that may renderthem attractive candidates for the coating of metal-implant bearing surfaces. Metastable
Optical Computer aided tomography (CAT) is being investigated as a potential in situ diagnostic for measuring plasma uniformity without making assumptions
We propose to measure the dielectric constant [epsilon] and the thermodynamic temperatue T of helium near 273.16 K and to calculate the pressure p([epsilon],T)
We suggest a new design configuration for thermoacoustic refrigeration that optimises the refrigeration effect caused by both the standing wave and the

The discharge coefficient in critical nozzles flowing N 2, Ar, CO 2, and H 2 in the Reynolds Number range (2,000 to 22,000) is studied computationally to assess
Potential improvements of the Coefficient of Performance (COP) were investigated for R-407C at cooling and heating conditions of a residential heat pump. The
The attention of wind engineers and extreme value climatologists has been focused in the last few decades on estimates of basic windspeeds, that is, wind speeds
An improved design for a guarded transfer standard in the resistance range 1 M[Ω] to 100 G[Ω] is described. Existing transfer standards and limitations are
This paper describes resistance ratio measurements using cryogenic current comparator (CCC) devices that operate at 77 K. The magnetic shields are Thallium
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
