Conference Report: NIST Workshop on Thin Dielectric Film Metrology

August 1, 1998
Author(s)
Barbara J. Belzer, James R. Ehrstein
A two-day workshop on Thin Dielectric Film Metrology was conducted by the Semiconductor Electronics Division, October 30-31, 1997, at NIST Gaithersburg. The purpose was to assess the status of optical metrology for application to semiconductor thin film

Coolant Flow in Surface Grinding with Non-Porous Wheels

August 1, 1998
Author(s)
P Hryniewicz, A Z. Szeri, S Jahanmir
A parameter that is often used in the assessment of cooling efficiency in grinding is the amount of fluid that flows through the grinding zone. This paper shows that when grinding with wheels possessing no bulk porosity, only a portion of the flow through

Data Selection for Broadcast News CSR Evaluations

August 1, 1998
Author(s)
W M. Fisher, Walter S. Liggett Jr, A N. Le, Jonathan G. Fiscus, D S. Pallett
Composition of the 1997 Hub-4 broadcast news test set is discussed. The composition is based on concurrent selection of a statistically equivalent test set for a future evaluation, adjustment of the set to match the training data, and other considerations

Elastic and Inelastic Collisions of Cold Spin-Polarized 133 Cs Atoms

August 1, 1998
Author(s)
P J. Leo, Eite Tiesinga, Paul S. Julienne, D K. Walter, S Kadlecek, T G. Walker
We present theoretical calculations of thermally averaged elastic cross sections and spin-relaxation rate coefficients in the temperature range 0.1 to 300 K for Magnetically trapped doubly polarized cesium atoms. The calculations reproduce the recent

Hardness Testing of Ceramics

August 1, 1998
Author(s)
George D. Quinn
An overview of hardness testing of ceramics is presented. Conventional test methods are discussed, particularly with respect to major sources of experimental error and standardization. Two NIST Standard Reference Materials (SRMs) are highlighted. Emerging

High Heat Flux Sensors Calibration Using Blackbody Radiation

August 1, 1998
Author(s)
A V. Murthy, Benjamin K. Tsai, Robert D. Saunders
This paper deals with the radiative calibration aspects of high heat flux sensors using blackbody radiation. Several heat flux sensors were calibrated up to 50kW/m 2 in the last two years using a 25 - mm diameter aperture variable temperature blackbody and
