Benefits and Costs of Research: Two Case Studies in Building Technology.

July 1, 1996
Author(s)
Robert E. Chapman, S K. Fuller
The National Institute of Standards and Technology (NIST) is improving its resource allocation process by doing "microstudies" of its research impacts on society. This report is the outgrowth of a series of microstudies prepared by NIST's Building and Fire

Charge-transfer rate constants for N+/2 (v=0-4) with Ar at thermal energies

July 1, 1996
Author(s)
S Kato, J A. de Gouw, C D. Lin, V M. Bierbaum, S R. Leone
Rate constants for the charge-transfer reaction N 2 +(V)+ Ar>N 2+Ar + are measured at thermal energies as a function of initial vibrational excitation by laser-induced fluorescence. The reaction is slow for v=0, whereas the rate constants for v=1-4 are

January 17, 1995 Hyogoken-Nanbu (Kobe) Earthquake: Performance of Structures, Lifelines, and Fire Protection Systems (NIST SP 901)

July 1, 1996
Author(s)
R M. Chung, D B. Ballantyne, E Comeau, T L. Holzer, Daniel M. Madrzykowski, A J. Schiff, William C. Stone, J Wilcoski, R. D. Borcherdt, J D. Cooper, Hai S. Lew, Jack P. Moehle, L H. Sheng, A W. Taylor, I Bucker, John(Jack) R. Hayes Jr., E V. Leyendecker, T O'Rourke, M P. Singh, M Whitney
The January 17, 1995 Hyogoken-Nanbu earthquake of magnitude 7.2 in JMA scale (Mw = 6.9), which struck Kobe, Japan and its surrounding area was the most severe earthquake to affect that region this century. The earthquake resulted in more than 6,000 deaths

Lorentz-Lorenz Shift in an Inhomogeneously Broadened Medium

July 1, 1996
Author(s)
J Guo, Alan Gallagher, J W. Cooper
A simple calculation shows that the Lorentz-Lorenz shift due to the local field correction remains significant in situations where the inhomogeneous broadening of a medium exceeds the homogeneous broadening. As an illustration, the calculated selective

Representing Designs With Logic Formulations of Spatial Relations

July 1, 1996
Author(s)
Scott Chase
A new method of describing designs by combining the paradigms of shape algebras and predicate logic representations is proposed. Representing shapes and spatial relations in first order predicated logic provides a natural, intuitive method of developing

The Economics of New-Technology Materials: A Case Study of FRP Bridge Decking

July 1, 1996
Author(s)
M A. Ehlen, Harold E. Marshall
Many new materials are bing developed from polymers, metals, and ceramics. Industry is beginning to introduce some of these high-performance or new-technology materials in construction and manufacturing applications because the materials have advantages

Thermal Noise in Lossy Waveguides

July 1, 1996
Author(s)
Dylan F. Williams
This work rigorously treats thermal electromagnetic noise in lossy waveguides and develops explicit modal equivalent­ circuit representations for the noise generated by arbitrary passive networks embedded in them. The results show that the formulations in

Variant Design for Mechanical Artifacts: A State-of-the-Art Survey

July 1, 1996
Author(s)
James E. Fowler
Variant design refers to the technique of adapting existing design^M specifications to satisfy new design goals and constraints. A survey of^M approaches supporting variant designs is presented. Capabilities used in^M current commercial computer aided

Writing CGI scripts in Tcl

July 1, 1996
Author(s)
Don E. Libes
CGI scripts enable dynamic generation of HTML pages. This paper describes how to write CGI scripts using Tcl. Many people use Tcl for this purpose already but in an ad hoc way and without realizing many of the more nonobvious benefits. This paper reviews
