This report describes the use of combinatorial test methods to reduce the cost of testing for the Document Object Model Events standard while maintaining an equivalent level of assurance. More than 36,000 tests - all possible combinations of equivalence
Optical frequency combs can be employed over a broad spectral range to calibrate laser frequency or vacuum wavelength. This article describes procedures and techniques utilized in the Precision Engineering Division of NIST (National Institute of Standards

Quantum dots (QDs) of two different surface chemistries (carboxyl (COOH) and poly ethylene glycol (PEG) modified) were utilized to determine the impact of surface functionality on QD mobility and distribution in Pseudomonas aeruginosa PAO1 biofilms

Building information models (BIMs) are maturing as a new paradigm for storing and exchanging knowledge about a facility. BIMs constructed from a CAD model do not generally capture details of a facility as it was actually built. Laser scanners can be used

The development of a reference measurement procedure to support the cardiac troponin I (cTnI) standardization initiative is described. The reference measurement procedure will be used to assign reference values to serum-based secondary standards. A

There is growing recognition cells can sense and respond to the mechanical properties of tissue scaffolds and that these interactions are critical in optimizing scaffold design [1-4]. Previous studies in planar 2D culture format have shown that human bone
Fire resistive materials (FRMs) serve a critical function in insulating (steel) structures to limit steel temperature rise during a fire exposure. This paper provides an overview of FRMs, focusing on the measurement of their thermophysical properties

We report the use of atomic layer deposition (ALD) coating as a nanobiosensor functionalization strategy for enhanced surface immobilization that may enable higher detection sensitivity. Three kinds ofALDcoating films, Al2O3,TiO2, and SiO2, were grown on

We describe a method to estimate the scale errors in the horizontal angle encoder of a laser tracker in this paper. The method does not require expensive instrumentation such as a rotary stage or even a calibrated artifact. An uncalibrated but stable
We report a miniaturized phase shifter operating in the frequency range from 5 GHz to 7 GHz for noise-parameter extraction. Such a tunable solid-state unit represents a significant reduction in the size and mass as a source-pull component, compared to its

We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and National Institute of Metrology (NIM-China). We report optical fiber-based power measurements at nominal wavelengths of
