Rapid prototyping of microfluidic handling devices has gained popularity due to the ability to quickly test and modify new design features several times in one
A new sampling comparator design employing a signal-dependent biasing scheme is described. The dynamic bias significantly reduces signal-induced thermal error
In coordinate metrology, evaluating task specific measurement uncertainty can be difficult, a problem which prompted the current development of several related
This report describes a database model currently under development at the Manufacturing System Integration Division (MSID) of the National Institute of

Abstract ' We describe the design, fabrication, and testing of a nonlinear reference device that has a calculable phase relationship between the fundamental
This paper describes how to correct for systematic errors in one-port vector network analyzer calibrations that are caused by modeling errors in the one-port

We present the results of studies of solution-based attachment of long-chain aliphatic molecules to hydrogen-terminated Si surfaces formed to pursue the
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometrics
In order to facilitate nationwide analysis of ventilation and indoor air quality issues in residential buildings, a set of homes has been defined to represent
This paper describes the development of a unique fluorescence based DNA diagnostic assay that does not require pre-labeling of the target oligomer prior to
Stress corrosion cracks typically nucleate at a stress concentration in the surface and propagate away from the surface on a plane perpendicular to the applied
The stress corrosion cracking behavior of precipitation hardened alloys may depend on a large number of microstructural parameters that vary during fabrication
Prof. Leonard Mandel led his students through a number of rather widely recognized experiments over the course of his career, but also through an extremely
We develop models for light scattering appropriate for glossy and matte paints. Volume scattering is treated in the single scattering regime and the diffusive
Regenerative heat exchangers have had a significant influence on the development of small refrigerators for cryogenic applications. The optimized design of
