Chemical Species and Temperature Mapping in Full Scale Underventilated Compartment Fires

July 5, 2010
Author(s)
Andrew J. Lock, Matthew F. Bundy, Erik L. Johnsson, Kelly M. Opert, Anthony P. Hamins, Cheolhong Hwang, Ki Y. Lee
Many injuries and deaths throughout the world are caused by fires each year. Many of the deaths are the result of toxic gas inhalation, such as carbon monoxide, by a victim remote from the actual fire source. In order to facilitate better building

Scanning Kelvin Force Microscopy For Characterizing Nanostructures in Atmosphere

September 30, 2007
Author(s)
Joseph Kopanski, Muhammad Afridi, Stoyan Jeliazkov, Weirong Jiang, Thomas R. Walker
The Electrostatic Force Microscope (EFM) and its variants are of interest for the measurement of potential distributions within nanostructures, and for work function measurements of gate metals for next generation CMOS. In phase mode, the EFM measures

Fire Structure Interface and Thermal Response of the World Trade Center Towers. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5G) ***DRAFT for Public Comments***

September 1, 2005
Author(s)
Kuldeep R. Prasad, Howard R. Baum
The collapse of the World Trade Center towers on September 11, 2001, resulting from a combination of aircraft impact damage and subsequent fires, was studied as part of the Federal Building and Fire Safety Investigation of the WTC Disaster. This report

Real-Time I/O Performance Metrics and Tests for Industrial Ethernet

April 28, 2004
Author(s)
James D. Gilsinn
Real-time input/output (I/O) communication over Ethernet is still fairly new in the industrial environment. There are many questions about the reliability and performance that have to be answered before industrial Ethernet can be utilized in most

Suppression of Cup-Burner Flames Using Carbon Dioxide in Microgravity

April 1, 2004
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to

Magnetization Dynamics Modeled in Magnetic Thin Films

March 1, 2003
Author(s)
Robert D. McMichael
One of the challenges facing designers of high data rate computer hard drives and magnetic memory chips is that for most magnetic metals, it typically takes a fewnanoseconds for the magnetization to come to rest after it has been switched or bumped by a

Extinction Characteristics of Cup-Burner Flame in Microgravity

January 1, 2003
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to

BACnet Unraveled

August 1, 2001
Author(s)
Steven T. Bushby
Publication of ASHRAE and ANSI's BACnet communication protocol in 1995 ushered in a new era for building automation and control systems, making it possible to integrate building control products designed by different manufacturers. This change has proved

Single-Integral-Equation Method for Scattering by Dielectric Cylinders

July 1, 2001
Author(s)
Egon Marx
Electromagnetic scattering of an incident plane monochromatic wave by dielectric or finitely conducting infinite cylinders of arbitrary shape, possibly in the presence of a substrate, can be reduced to the solution of scalar Helmholtz equations in two

SO x Radical Monoanions--Reactions in Solution and in the Gas Phase

February 1, 1999
Author(s)
Robert E. Huie, L W. Sieck
Sulfur dioxide, SO 2, is a major air pollutant and a natural trace atmospheric constituent. The major anthropogenic source of SO 2 is the combustion of fossil fuels, although much also arises from scrubbing natural gas and from smelting sulfide ores (1)

Mean Recurrence Intervals of Ultimate Wind Loads

July 1, 1998
Author(s)
Emil Simiu, A N. Heckert, T Whalen
The attention of wind engineers and extreme value climatologists has been focused in the last few decades on estimates of basic windspeeds, that is, wind speeds with 50 year or 100 year mean recurrence intervals (MRIs). Recently, however, efforts have been

Crystal Structure and Properties of Ba 5 Fe 4 ^Ti 10 O 31

February 23, 1998
Author(s)
T Siegrist, Terrell A. Vanderah, A P. Ramirez, Richard G. Geyer, Robert S. Roth
Using single-crystal and powder X-ray diffraction methods, the crystal structure of the new compound Ba 5Fe 4Ti 10O 31 was determined and its magnetic and dielectric properties were measured. Ba 5Fe 4Ti 10O 31 crystallizes in space group P6 3/mcm (no. 193)

On Migrating ISO 10303 PMI Models to a Common Core

January 4, 2023
Author(s)
Allison Barnard Feeney, Thomas Thurman
Industrial users of ISO 10303 STandard for the Exchange of Product Model Data (STEP) protocols needed the ability to exchange design product data that is in conformance with recently updated ISO geometric product specification (GPS) standards, the American
