Verification and Validation of CFAST, A Model of Fire Growth and Smoke Spread

February 19, 2017
Author(s)
Walter W. Jones, Richard D. Peacock, Glenn P. Forney, Paul A. Reneke
CFAST is a zone model capable of predicting the environment in a multi-compartment structure subjected to a fire. It calculates the time evolving distribution of smoke and fire gases and the temperature throughout a building during a user-specified fire

Collaboration Technologies for Global Manufacturing

October 1, 1999
Author(s)
Michelle P. Steves, Amy Knutilla
One impact of the globalization of manufacturing is the growing requirement for teams that are not co-located to collaborate using shared information. In this paper, we present our approach to instituting and assessing collaboration technologies for
