We use an atomistic tight-binding theory to study arrays of T-shaped GaAs/AlGaAs quantum wires. An atomistic approach allows us to provide a theory of the...
The spectrum of xenon excited in a low-inductance vacuum spark was photographed at high resolution in the region 9.5 nm - 15.5 nm. The observed transitions were...
As markets become unexpectedly turbulent with a shortened product life cycle and a power shift towards buyers, the need for methods to rapidly and cost...

The paper describes a model-driven method of systems integration using legacy models. The method defines relationships between elements of legacy models to...
A photometer/tristimulus colorimeter has been developed at the National Institute of Standards and TEchnology (NIST) to realize a color scale. A novel...

We report here new measurements of the extent of polymerization of rabbit muscle actin as a function of T , initial G-actin concentration and initiating salt...
We measured the elastic constants of a natural-quartz sphere using resonance-ultrasound spectroscopy (RUS). Our measurements of the near-traction-free...

Task specific CMM measurement uncertainty statements can be generated using computer (Monte Carlo) simulation. REcently, commercial products using this powerful...
Lighting controls protocols are discussed. Key elements are power and flexibility, both in system design and implementation, and in operation. The overriding...
This paper describes a fault detection method developed for application to variable-air-volume (VAV) boxes. VPACC (VAV Box Performance Assessment Control Charts...

Microboiling events associated with the fast transient heating of a micrometer-scale metallic thin film heater immersed in water have been studied. The effect...
This paper is mostly a review of the progress made at NIST in pursuing a capacitance standard based on the charge of the electron. We briefly introduce the...
We have quantitatively compared spin momentum transfer effects in FM/Cu multilayers, with FM = Co, Co 90Fe 10, Ni 80Fe 20, Ni 40Fe 10Cu 50, and Fe. All of the...
It has long been realized that the sublethal effects of smoke can affect survival in fires, but only sparse data were available on which to base fire safety...
