Luminance measurements of small areas of black pixels on white-screen backgrounds are often used as metrics in display measurements, such as character-stroke
This work focuses on obtaining data to perform realistic finite element models of residual stresses in composite parts made of toughened epoxy thermosets. The
Several digital algorithms are coming into general use. A certificate containing a key for one algorithm can be signed with a different algorithm. This paper
The National Bureau of Standards' Center for Fire Research and the Fire Retardant Chemicals Association were formed within a year of each other. The former has

Rapid thermal processing (RTP) is a key technology for the cluster tool, single wafer manufacturing approach that is used to produce integrated circuits at
This paper describes the sensing portion of a system used to convert an existing 30-ton high bay bridge crane to computer control for automated placement of
Cement-based materials are usually composites, where the matrix consists of cement paste. Cement paste is a material formed from the hydration reaction of
Sensors are used in a broad range of applications, from machinery condition monitoring and industrial automation to patient condition monitoring in hospitals
Recent experimental results based on x-ray reflectivity, ellipsometry and positron annihilation spectroscopy, etc. have demonstrated that physical properties of
X-ray diffraction topography has been used as a nondestructive characterization tool to investigate single-crystal sapphire for window and dome applications. A

Incorporating wastes into concrete on an appropriately selective basis could help to solve some of the problems encountered in waste management. Some industrial
Multi-step stress relaxation data from a DGEBA/m-PDA epoxy resin is modeled using a nonseparable nonlinear constitutive equation. The form of the equation is
We developed an electrical test to evaluate interconnections in packaged, electrostatic-discharge (ESD) protected modules. The ESD protection circuit, which in
In this paper, I will discuss the theory and application of polarized light scatter. Recent measurements have shown that some sources of scatter, including
