Accurate heat release rate measurements provide essential information to defining the fire safety characteristics of products. The size, complexity, and cost of full-scale fire tests make achieving accurate and quantitative results a serious challenge. A

The third Industrial fluid properties simulation challenge was held from March to September 2006. As in the previous two events, contestants were challenged to predict specific, industrially relevant, properties of fluid systems. Their efforts were judged
The measurement of forces from piconewtons to millinewtons is an area of interest from both an applied and pure research standpoint, however creating a link between small forces and the International System of Units (SI) has been difficult. In this work, a

House dust originates from both internal and external sources and has been identified as one of the primary sources of lead exposure for children (http://www.epa.gov/lead). House dust is also a repository for pesticides, flame retardants, and other
Sandwich plates with cellular metal cores are being widely considered for blast mitigation applications, due largely to the energy absorption capacity of the cellular core material. Computational simulations have shown that sandwich plates exhibit reduced

Topographically directed, evaporation driven self-assembly (EDSA) of nanoparticles is a promising manufacturing technique that combines the control of top-down lithography with the speed of bottom-up self-assembly. , We have developed a modeling
Models of cement paste microstructure that discretize particles on a regular mesh generally must use very fine meshes to resolve the smallest particles. Particularly if the particle size distribution is broad, this leads to undesirably large numbers of
The spectral radiance of the 185-nm and 254-nm lines in two positive column mercury discharge lamps was measured over a wide range of operating conditions. The lamps had internal diameters of 5 and 23 mm. Argon was used as a carrier gas. The lamps were
TheO1 (short terminology for theorectical variance #1) is derived based on psi_y 2 (t,T), a variance that separates the Allan variance's sampling or observation interval form its averagin (tau) of sampled y(t), the fractional-frequency measurements in a

Highly ordered morphological features were characterized for molecular dynamics simulated alkyl-modified silica models that represent chromatographic materials with enhanced shape recognition capability. Deep cavities (8-10 wide) within the alkyl chains
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

A new dynamic testing apparatus has been built at the National Institute of Standards and Technology (NIST) to measure dynamic material properties for machining simulation and other applications. This apparatus-the NIST Pulse Heated Kolsky Bar - is based
We have developed a method to examine how residual stress affects the values of the elastic moduli of thin films determined from surface acoustic wave spectroscopy experiments. Because the effective second-order elastic moduli in the stressed state are a

The semiconductor electronics industry places significant demands upon secondary electron imaging to obtain dimensional measurements that are used for process control or failure analysis. Tolerances for measurement uncertainty and repeatability are smaller
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

High-velocity oxygen-fuel (HVOF) spraying stands out among the various processes to improve metal and ceramic coating density and surface characteristics. This paper explores microstructure development, coating characterization and properties of HVOF
The ubiquitous computer now touches nearly every aspect of human life. The promise of information technology is improvement to the quality of life. Maintaining trust and confidence in information technology is central to keeping that promise. This is
X-Ray Photoelectron Spectroscopy (XPS) is being used to an increasing extent for the characterization of new gate-oxide materials, particularly for the determination of film composition, uniformity, and thickness. A key parameter for film-thickness
The mechanisms by which polymers form carbonaceous chars as a result of thermal and oxidative degradation is an interesting scientific problem, which has important commercial (formation of carbon fibers and nanostructures) and public safety implications
