Simulating Fire Effects on Complex Building Structures.

December 1, 2005
Author(s)
Howard R. Baum
The purpose of this lecture is to assess the current state of our ability to simulate the consequences of a fire in a large building, and suggest some areas where improvement is needed. Attention is focused on the coupling of fire dynamics simulations and

Technique for Extrapolating Absorption Coefficient Measurements to High Temperatures

December 1, 2005
Author(s)
Kaoru Wakatsuki, Stephen P. Fuss, Anthony Hamins, Marc R. Nyden
An extrapolation technique that provides semi-quantitative estimates for the infrared absorption coefficients of gaseous fuels at temperatures beyond those for which measurements are generally practical (>700 K) is presented. The new method is based on a

Trapping and Moving Atoms on Surfaces

December 1, 2005
Author(s)
Robert Celotta, Joseph A. Stroscio
We have used a scanning tunneling microscope to laterally reposition a single cobalt atom adsorbed on the (111) face of a copper crystal. We find that the atom follows a complex path determined by the trapping potential of the STM tip, the effects of
