The results of experimental studies on multimodal biometric systems for small-scale populations have shown better performance compared to single-mode biometric
Service-discovery systems aim to provide consistent views of distributed components under varying network conditions. To achieve this aim, designers rely upon a
We compare first-principles (FP) calculations of the ionic effective charges, phonon frequencies, and static dielectric permittivities k s of several perovskite

A self-hardening calcium phosphate cement (CPC-I), consisting of tetracalcium phosphate (TTCP) and dicalcium phosphate anhydrous (DCPA), has been shown in
Baffles are often placed in integrating spheres to accommodate the non-ideal aspects of other sphere components. These include detectors, sources, sphere wall
The polarization of light scattered by the surface of a material contains information that can be used to identify the sources of that scatter. In this paper

Sun photometers are used to characterize the radiative properties of the atmosphere. They measure both the incident solar irradiance as well as the sky radiance
David W. Allen, George P. Eppeldauer, Steven W. Brown, E A. Early, Bettye C. Johnson, Keith R. Lykke
We describe the development of a mechanically simple, radiometrically stable transfer radiometer designed for both radiance and irradiance measurements. The
Our customers usually measure mask features in order to make a business decision, such as whether or not to ship a mask to a customer. A simple cost/benefit
The NIST M48 coordinate measuring machine (CMM) was used to measure the average diameter of two precision, silicon spheres of nominal diameter near 93.6 mm. A
This paper discusses the modeling and control of a nanopositioning flexure hinge mechanism with a piezoelectric actuator. A complete dynamic model for the

The turning process with varying spindle speed is investigated. The well-known turning model is presented and the governing delay-differential equation with
We analyzed the high frequency dielectric relaxation mechanism in high-k composite materials using film substrates made of low loss organic resin filled with
Incomplete hemispherical irradiation of the sample (or collection of radiation, in the reverse geometry) in an integrating sphere reflectometer is unavoidable
