Analysis of Large-Scale Fire Test Data

January 1, 1991
Author(s)
Richard D. Peacock, Vyto Babrauskas
Large-scale room fire testing has evolved from simple fire performance measurements such as intensity and duration of 'room fires' to sophisticated measurements to understand the properties which cause the fire. This paper provides a overview of typical

Anharmonic Phonons and the Isotope Effect in Superconductivity

January 1, 1991
Author(s)
V Crespi, Marvin Cohen, David R. Penn
Anharmonic interionic potentials are examined in an Einstein model to study the unusual isotope-effect exponents for the high-T(c) oxides. The mass dependences of the electron-phonon coupling constant λ and the average phonon frequency square-root <ω2> are

Apparel STEP Translator

January 1, 1991
Author(s)
Howard T. Moncarz, Yung-Tsun Lee
This paper describes the implementation of a prototype computer program for translating apparel pattern data between different file storage formats. The software demonstrates the feasibility of using a single, standard format as a mechanism for exchanging

Application Protocols for Mechanical Parts Production Plan

January 1, 1991
Author(s)
Chuck Stark
The STandard for the Exchange of Product model data (STEP) is being developed as an international standard. The National PDES Testbed was established at NIST specifically to address the development and testing of STEP, and to serve U.S. industry in its use

Atomic and Molecular Manipulation With the Scanning Tunneling Microscope

January 1, 1991
Author(s)
Joseph A. Stroscio, D Eigler
The prospect of manipulating matter on the atomic scale has fascinated scientists for decades. This fascination may be motivated by scientific and technological opportunities, or from a curiosity about the consequences of being able to place atoms in a

Atomic Spectra and Wavelength Standards

January 1, 1991
Author(s)
William C. Martin, Wolfgang L. Wiese, Arlene Musgrove, Jeffrey R. Fuhr, J Sugar, Joseph Reader, Daniel E. Kelleher, Karen J. Olsen, Peter J. Mohr, G R. Dalton, C S. Grant, G Eichorn
