A Welding Cell That Supports Remote Collaboration

September 30, 1999
Author(s)
James D. Gilsinn, William G. Rippey, Joseph A. Falco, Timothy P. Quinn, Robert Russell, Keith A. Stouffer
Discrete part manufacturers using robotic arc welding cells often have several more geographically distributed plants than welding experts. This ratio often leads to costly downtimes due to both logistic and communication deficiencies between weld

Fire Dynamics Simulator (Version 2) -- User's Guide

November 1, 2001
Author(s)
Kevin B. McGrattan, Glenn P. Forney, J E. Floyd, Simo A. Hostikka
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) modelof fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

Comparison of Two Methodologies in HAZARD I Fire Egress Analysis.

September 30, 1998
Author(s)
M M. Kostreva, L C. Lancaster
Within the framework of HAZARD I, fire egress analysis is performed using the EXITT program. Yet another way to analyze fire egress employs newly developed multiple objective dynamic programming. This paper compares these two approaches by applying them to

Improved Mesoscale Segmentation of Concrete from 3D X-ray Images Using Contrast Enhancers

June 28, 2018
Author(s)
Pietro Carrara, Rolands Kruse, Dale P. Bentz, M Lunardelli, Thorsten Leusmann, P Varady, Laura De Lorenzis
Obtaining the mesostructure of concrete from X-ray computed tomography (CT) requires segmentation of the data into distinct phases, a process complicated by the limited contrast between aggregates and mortar matrix. This paper explores the possibility to

A Benchmark Open-Source Implementation of COSMO-SAC

February 14, 2020
Author(s)
Ian H. Bell, Erik Mickoleit, Chieh-Ming Hsieh, Shiang-Tai Lin, Jadran Vrabec, Cornelia Breitkopf, Andreas J?ger
The COSMO-SAC modeling approach has found wide application in a range of industries due to its good predictive capabilities. While UNIFAC is in general more accurate than COSMO-SAC, the UNIFAC model contains many adjustable parameters and cannot be used if

Fire Conditions for Smoke Toxicity Measurement

May 1, 1994
Author(s)
Richard G. Gann, V Babrauskas, Richard D. Peacock, J R. Hall
This paper identifies those fire conditions most often present when smoke toxicity is the cause of death. It begins with a review of the evidence that smoke-inhalation deaths are in the majority in fire fatalities in the United States. Next, there is an

U.S. Government Activities to Protect the Information Infrastructure

April 28, 1997
Author(s)
Dennis D. Steinauer, Shirley M. Radack, Stuart W. Katzke
This paper is a survey of recent activities of the legislative and executive branches of the U.S. Government (and of some joint activities of government and industry) that involve the security of the evolving information infrastructure. Over the past few
