This paper introduces recent advances in scatterfield microscopy using improved normalization and fitting procedures. Reduced measurement uncertainties are...
The calculation of natural gas viscosity has been implemented many different ways including the use of constants. Different methods of calculating natural gas...
Critical flow venturis (CFVs) can be used to measure flow under transient pressure, temperature, and flow conditions with k=2 uncertainties of 0.4 % or less...
We report progress in testing a dynamic gravimetric standard using both steady and unsteady water flows. For steady flows in the range 10 kg/s to 60 kg/s, the...
Measurements of the flow and the energy content of natural gas rely on equations of state to compute four thermodynamic properties: 1) compressibility factor; 2...
The manufacturing companies are facing the challenging dilemma on how to achieve better quality products while reducing manufacturing costs and define the...
This paper recommends practices for development and deployment of modeling, simulation and analysis (MS&A) tools for homeland security applications. The set of...
This paper proposes a framework for application of system dynamics modeling to sustainable manufacturing. Sustainable manufacturing involves interaction of...

Optics in EUVL exposure tools are known to suffer reflectivity degradation, mostly from the buildup of carbon. The sources of this carbon have been difficult to...
Fiber optic networks are an attractive means for the remote distribution of highly stable frequencies from optical clocks. The highest performance is achieved...
Standard materials certified using electrochemical techniques include many of the most-used certified reference materials (CRMs). These CRMs provide...
At NIST, said Dr. Rochford, "we are very broad, but we focus like a laser on measurement science." NIST also helps develop standards and promote technology. He...
Modeling and simulation (M&S) techniques are increasingly being used to solve problems and aid decision making in many different fields. It is particularly...
A number of modeling, simulation and analysis (MSA) efforts have evolved to support homeland security initiatives. Various organizations involved in homeland...
