Active Cavity Radiometer Based on High-TC Superconductors

January 1, 1998
Author(s)
Joseph P. Rice, Raju V. Datla, Leila R. Vale, David A. Rudman, M L. Sing, D Robbes
To implement the detector-based radiometric scale in the new Medium Background infrared [MBIR] facility at the National Institute of Standards and Technology [NIST], we have developed an electrical substitution cavity radiometer that can be operated at

Advances in NIST Standard Rockwell Diamond Indenters

January 1, 1998
Author(s)
Jun-Feng Song, Samuel R. Low III, David J. Pitchure, Theodore V. Vorburger
Recent developments in standard hardness machines and microform calibration techniques have made it possible to establish a worldwide unified Rockwell hardness scale with metrological traceability. This includes the establishments of the reference

An Integrated Approach to Optimal Three Dimensional Layout and Routing

January 1, 1998
Author(s)
Simon Szykman, J Cagan, P Weisser
This paper describes the combination of previously-developed component placement and routing algorithms into an integrated computational approach to product layout optimization. Previous work introduced simulated annealing-based algorithms for optimal

Analysis of the Single-Fiber Fragmentation Test

January 1, 1998
Author(s)
Tinh Nguyen, Joannie W. Chin, Tze-Jer Chuang, S Lee
An analysis of the single-fiber fragmentation test was investigated. An approximate solution for the stress fields of a fiber embedded in a polymer matrix of different elastic moduli was obtained by the Eshelby method. The fiber was modeled as a prolate
