We describe recent progress at NIST in the development of compact, low-power atomic frequency references based on microfabrication processes. The physics...
We have measured the stability of a variety of photodiodes as they are irradiated with UV light from a pulsed excimer laser source operating at 157 nm using a...
Near-field scanning optical microscopy and Fourier analysis polarimetry are combined to obtain quantitative maps of the local retardance, (resulting from strain...

This paper reviews practices in the expression of uncertainty in the experimental literature for thermodynamic property measurements with determinations of...
We describe a frequency-stabilized cavity ring-down absorption spectrometer with automated scanning capabilities. The system utilizes the comb of ring-down...

In a collaborative computer-supported engineering environment, the interoperation of various applications will need a representation that goes beyond the...
The Display Metrology Task Group of the Video Electronics Standards Association is developing the next Flat Panel Display Measurements Standard. The document's...
SOFM 2004 took place September 28-30, and was hosted by NIST's Optoelectronics Division in Boulder, Colorado, in cooperation with the Optical Society of America...
ckground: High concentration topical fluorides are commonly used to prevent caries in patients with compromised salivary function due to radiation and...
This paper has been presented as a plenary Lecture at the Eighteenth International Conference on Chemical Thermodynamics held August 17-20, 2004, in Beijing...

We investigate theoretically and experimentally how quantum state-detection efficiency is improved by the use of quantum information processing (QIP)...
This note concerns the mathematical aspects for several biometric algorithms in the recognition or identification problem. It is assumed that a biometric...
The certification of ITS 90 fixed-point cells from the Ar triple point (83.8058 K) to the Ag freezing point (1234.93 K) is an integral part of the calibration...

We present straight-forward models and representations for RF and image mixers, and develop simple rules for transforming electrical problems involving mixers...
We describe a prototype scalable viscometer aimed at facilitating rapid measurements of multiple samples. The device simultaneously measures the viscosity of...

This paper presents a discussion of standards requirements for LADAR. Two specific questions are addressed: (1) is there a need for such standards and (2) what...
Nanocomposites based on three different shapes of nanoscale particles, sphere (silica), plate (clay), and tube (carbon nanotube), were prepared and the...
Previously, it has been suggested that in low water-to-cement ratio (w/c) concretes, the coarser cement particles could be replaced by an inert filer with...
