The basic goal of the Advanced Optics Metrology program at NIST''s Manufacturing Engineering Laboratory is to help industry ensure that their measurement
Six new Hg triple-point (TP) cells (234.3156 K) were manufactured in the NIST PRT Laboratory for use in the realization of the International Temperature Scale
The program in atomic spectroscopy at NIST continues to provide accurate reference data on spectral lines and energy levels for a wide variety of important
As part of a research project for the Combined Calibration Group (CCG) of the U.S. Armed Forces, three rugged fixed-point cells were developed for use in dry
Experiments in Bose-Einstein condensation provide an unusually direct view of the working of quantum wave mechanics. We make use of two internal states of Rb-87

The Symposium on Thermophysical Properties represents a series of conferences that started in 1959 at Purdue University, which at the that time was the home of
The NIST Low Frost-point Humidity Generator (LFPG) produces water vapor gas mixtures with mole fractions from approximately 5 nmol/mol to 4 mmol/mol for
The history of the research program on thermophysical properties of refrigerants at the National Institute of Standards and Technology (NIST) is described in
Preliminary results are reported on the non-uniqueness of the ITS-90 using high temperature SPRTs (HTSPRTs) in the range 660 C to 962 C. To achieve temperature
This paper presents an overview of a neutral reference architecture for integrating distributed manufacturing simulation systems with each other, with other
In interlaboratory comparisons, laboratories sometimes use a transfer instrument to realize the value of a laboratory standard to compare the relative biases of
XML[Extensible Markup Language] developers today have at their disposal a variety of tools for achieving schema reuse. An often-overlooked reuse method is the
The private and public sectors depend heavily upon information technology (IT) systems to perform essential, mission-critical functions. As technology improves
