Absolute optical ranging using low coherence interferometry

July 20, 1991
Author(s)
B. L. Danielson, C. Y. Boisrobert
We describe a method for measuring submicrometer distances with an asymmetric fiber Michelson interferometer having an LED as a source of radiation. By measuring the phase slope of the Fourier components in the frequency domain, it is possible to locate

Anomalies Observed in Wafer Level Microwave Testing

July 10, 1991
Author(s)
Dylan F. Williams, Roger Marks, T H. Miers, A Cangellaris
Two anomalies have been observed in the course of developing planar wafer level standards for the testing of GaAs monolithic microwave integrated circuits. The first involves a low-frequency characteristic impedance change of microstrip and coplanar

Assessment Methodology for the Fire Performance of School Bus Interior Components.

July 8, 1991
Author(s)
E Braun, J H. Klote, S Davis, Barbara C. Levin, Richard G. Gann, M Paabo
A full-scale fire performance protocol for the evaluation of school bus seat assemblies was developed. This protocol is based on the results of full-scale testing of end-use seat assemblies and computer fire modeling of the ignition source and burning item

Self-Avoiding Random Surfaces: Monte Carlo Study Using Oct-tree Data- structures

July 1, 1991
Author(s)
John O'Connell, F Sullivan, Donald E. Libes, E Orlandini, M Tesi, A Stella, T L. Einstein
Self-avoiding random surfaces on a cubis lattice are studied by extensive Monte Carlo sampling. The surfaces have empty boundary and the topology of a 2-sphere. An oct-tree data structure allows good statistics to be obtained for surfaces whose plaquette

STEP On-Line Information Service User

July 1, 1991
Author(s)
Susan Katz
This document describes how to access the on-line STEP information service provided by the Information Services Center of the National PDES Testbed at NIST. The on-line information includes the latest STEP Parts, the Tokyo version of STEP, the PDES Toolkit
