Understanding the Fire Hazards of Grouped Electrical Cables

June 26, 2011
Author(s)
Kevin B. McGrattan, David Stroup
CHRISTIFIRE (Cable Heat Release, Ignition, and Spread in Tray Installations during FIRE) is an Office of Nuclear Regulatory Research (RES, US NRC) program to quantify the mass and energy released from burning electrical cables. The experimental program has

PDH-locked, frequency-stabilized cavity ring-down spectrometer

June 16, 2011
Author(s)
Joseph T. Hodges, A. Cygan, Piotr Maslowski, Katarzyna E. Bielska, S. Wojtewicz, J. Domyslawska, Hisashi Abe, R.S. Trawinski, R. Ciurylo
We describe a high sensitivity and high spectral resolution laser absorption spectrometer based upon the frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) technique. We used the Pound-Drever-Hall (PDH) method to lock the probe laser to the high

Examination of United States Carbon Dioxide Emission Databases

June 10, 2011
Author(s)
Robert P. Borthwick, James Whetstone, Jiann C. Yang, Antonio Possolo
This paper compared carbon dioxide emissions from plants obtained in two ways, first from the US Department of Energy, Energy Information Administration EIA-767 database and EIA-1605 Greenhouse Gas Reporting Program guidelines and second from the U.S. Envi

Five Grand Challenges in Pedestrian and Evacuation Dynamics

June 6, 2011
Author(s)
Jason D. Averill
This paper identifies five grand challenges in the multidisciplinary field of pedestrian and evacuation dynamics (PED). In order to maximize the ef-fectiveness of limited resources, the PED community would benefit greatly from a prioritized, consensus

Modelling Dynamic Aerosol Processes for Indoor Ultrafine Particles

June 5, 2011
Author(s)
Dong H. Rim, Lance L. Wallace, Andrew K. Persily, Jung I. Choi
This study has investigated aerosol transformation processes for four common sources of indoor ultrafine particles (UFP): gas stove, electric stove, candle, and hair dryer. For each of the four UFP sources, the temporal change in particle size distribution

Ultrafine Particles: 3 Years of Measurements in the NIST Test House

June 5, 2011
Author(s)
Lance L. Wallace, Andrew K. Persily, Steven J. Emmerich, Dong H. Rim, Chi P. Hoang, Cynthia H. Reed, Wang Fang, M E. Greene, Jung I. Choi
NIST has supported research characterizing ultrafine particle sources and dynamics for more than a decade. Over 90 % of ultrafine particles (UFP) produced by stovetop cooking on both gas and electric stoves were 10 nm. Using the NIST test house

Volatile Organic Compound Concentrations and Estimation of Optimal Source Strengths to Achieve a High Level of Acceptance Indoors using Multi- Zone Simulation

June 5, 2011
Author(s)
Helena Jarnstrom, William Stuart Dols, Cynthia H. Reed, Andrew K. Persily
This study investigated the possibility of identifying chemical pollutant profiles and concentration levels that result in a high level of acceptance indoors. In addition, a multi-zone simulation tool, CONTAM, developed by the National Institute of
