Development and Demonstration of a Method to Evaluate Bio-Sampling Strategies Using Building Simulation and Sample Planning Software

June 10, 2010
Author(s)
William S. Dols, Jayne B. Morrow, Andrew K. Persily, Brett Matzke, Landon Sego, Lisa Nuffer, Brent Pulsipher
response and recovery sampling approaches and technologies, the U.S. Department of Homeland Security (DHS), along with several other agencies, have simulated a biothreat agent release within a facility at Idaho National Laboratory (INL) on two separate

Effects of fiber gripping methods on single fiber tensile test using Kolsky bar

June 10, 2010
Author(s)
Jae Hyun Kim, Richard L. Rhorer, Haruki Kobayashi, Walter G. McDonough, Gale A. Holmes
Preliminary data by Ming Cheng et al. indicate minimal impact of strain rate on the tensile stress-strain behavior of Kevlar. However, technical issues associated with specimen preparation appear to limit the number of samples and show an undesirable

From the bottom up measuring bulk mechanical properties via microtechnology

June 10, 2010
Author(s)
Nicholas Barbosa, Sudook A. Kim, David T. Read
The micromechanics community has developed a large set of tools for measuring the properties of micro- and nano-scaled materials. These new tools have been successfully applied to a range of materials, most often in thin-film form, to determine the

Occupant Behavior in a High-rise Office Building Fire

June 10, 2010
Author(s)
Erica D. Kuligowski, Bryan L. Hoskins
Survey responses from occupants involved in a 32-story high-rise building evacuation during an actual fire were collected and analyzed to study the pre-evacuation period. Multiple regression models were used to test whether specific occupant, building, and

Rationale of Color Quality Scale

June 10, 2010
Author(s)
Yoshihiro Ohno, Wendy L. Davis
The color quality of solid state lighting (SSL) products is critical and is the subject of increasing attention. The CIE Color Rendering Index (CRI) [1] has been widely used for many years. However, the CRI is 35 years old and various problems of the CRI

State of Security Readiness

June 10, 2010
Author(s)
Ramaswamy Chandramouli, Peter M. Mell
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. However, the

Accurate light-time correction due to a gravitating mass

June 7, 2010
Author(s)
Neil Ashby, Bruno Bertotti
This technical paper of mathematical physics arose as an aftermath of the 2002 Cassini experiment, in which the PPN parameter γ was measured with an accuracy ς γ = 2.3 × 10 -5 and found consistent with the rediction γ=1 of general relativity. The Orbit

Dark pulse quantum dot diode laser

June 7, 2010
Author(s)
Mingming M. Feng, Kevin L. Silverman, Richard P. Mirin, Steven T. Cundiff
We describe an operating regime for passively mode-locked quantum dot diode laser where the output consists of a train of dark pulses, i.e., intensity dips on a continuous background. We show that a dark pulse train is a solution to the master equation for

Dynamic Deformation of Jacketed Lead Bullets Captured By High Speed DIC

June 7, 2010
Author(s)
Steven P. Mates
The development of high fidelity simulations of lead-cored bullet impacts on soft body armor, motivated by the need for improved armor designs and performance standards for law enforcement, requires accurate models for both the armor and the deformable

Edge structure of epitaxial graphene islands

June 7, 2010
Author(s)
Gregory M. Rutter, N Guisinger, Jason Crain, Phillip N. First, Joseph A. Stroscio
Graphene islands grown epitaxially on 6H-SiC(0001) were studied using scanning tunneling microscopy and spectroscopy. Under specific growth conditions, {approzimately equal}10 nm single-layer graphene islands are observed on top of the SiC buffer layer and

IUPAC-NIST Solubility Data Series

June 7, 2010
Author(s)
Allan H. Harvey, Mark Salomon
This is an editorial highlighting the IUPAC-NIST Solubility Data Series, which is published in JPCRD and produced by the IUPAC Subcommittee on Solubility and Equilibrium Data

Nanomechanical standards based on the intrinsic mechanics of molecules and atoms

June 7, 2010
Author(s)
Jon R. Pratt, Gordon A. Shaw, Douglas T. Smith
For more than a decade, instruments based on local probes have allowed us to touch objects at the nanoscale, making it possible for scientists and engineers to probe the electrical, chemical, and physical behaviors of matter at the level of individual

ThermoData Engine (TDE) Version 5.0 (Pure compounds, Equations of State, Binary mixtures, and Chemical Reactions)

June 7, 2010
Author(s)
Michael D. Frenkel, Robert D. Chirico, Vladimir Diky, Chris D. Muzny, Andrei F. Kazakov, Joe W. Magee, Ilmutdin M. Abdulagatov, Jeongwon Kang
ThermoData Engine (TDE) is the first and only full-scale software implementation of the dynamic data evaluation concept. The software provides critically evaluated thermochemical and thermophysical property values for pure compounds, binary mixtures, and

Understanding the Hazards of Grouped Electrical Cables

June 7, 2010
Author(s)
Kevin B. McGrattan, Andrew J. Lock, Marc R. Nyden, Jason Dreisbach, Nathan D. Marsh, David Stroup
CHRISTIFIRE (Cable Heat Release, Ignition, and Spread in Tray Installations during FIRE) is a U.S. Nuclear Regulatory Commission Office of Research program to quantify the mass and energy released from burning electrical cables. This type of quantitative
