Human Behavior in the World Trade Center Evacuation

March 3, 1997
Author(s)
R F. Fahy, Guylene Proulx
An explosion below the World Trade Center plaza in New York City on February 26, 1993, killed six workers, and resulted in injuries to over 1,000 occupants as they made their way out of the affected buildings. The explosion and subsequent fire caused

Three Dimensional Modeling of Intumescent Behavior in Fires

March 3, 1997
Author(s)
Kathryn M. Butler, Howard R. Baum, Takashi Kashiwagi
A method of studying the swelling and thermal behavior of intumescent materials using understanding of the basic physical and chemical processes is described. The material is treated as a highly viscous fluid with properties dependent on temperature. the

Analysis of Partially Grouted Masonry Shear Walls

March 1, 1997
Author(s)
P B. Shing, L Cao
Six partially grouted reinforced masonry shear walls that were tested at NIST are analyzed in this study. The main aim of the study is to assess the capability of some state-of-the-art finite element models in predicting the behavior of these wall

Atomic Physics in Ion Traps

March 1, 1997
Author(s)
C Monroe, John Bollinger
Ion traps allow researchers to control the position and movement of charged particles with exquisite precision, and provide a powerful way to study many atomic phenomena.

Building and Fire Research Laboratory Accomplishments, 1995-1996.

March 1, 1997
Author(s)
A J. Fowell
The Laboratory's mission is to enhance the competitivenesss of U.S. industry and public safety by developing performance prediction methods, measurement technologies and technical advances needed to assure the life cycle quality and economy of constructed

Emergence, Creativity, and Computational Tractability in Shape Grammers

March 1, 1997
Author(s)
Scott Chase
Emergence supports creativity in that emergent features can be considered unanticipated or accidental. The body of shape grammar research over the past quarter century has demonstratated that, within a strictly circumscribed space of designs, it is

Entropy Theory and Glass Transition: A Test by Monte Carlo Simulation

March 1, 1997
Author(s)
J Baschnagel, M Wolfgardt, W Paul, K Binder
A generalized entropy theory of glass formation is developed by merging the lattice cluster theoryfor the thermodynamics of semiflexible polymer melts at constant pressure with the Adam-Gibbsrelation between the structural relaxation time and the

Evidence for Glass and Spin-Glass Phase Transitions From the Dynamic Susceptibility

March 1, 1997
Author(s)
D Bitko, S N. Coppersmith, R L. Leheny, S R. Nagel, T F. Rosenbaum, N Menon
We present evidence that there is a phase transition, with a diverging static susceptibility, underlying the transformation of a liquid into a glass. The dielectric susceptibility, at frequencies above its characteristic value, shows a power-law tail
