F Case, John K. Brennan, Anne M. Chaka, Kerwin Dobbs, Daniel G. Friend, David Frurip, Peter A. Gordon, J Moore, Raymond D. Mountain, J Olson, Richard B. Ross, Martin Schiller, Vincent K. Shen
The third Industrial fluid properties simulation challenge was held from March to September 2006. As in the previous two events, contestants were challenged to predict specific, industrially relevant, properties of fluid systems. Their efforts were judged

A New Approach to Ventilation Measurements in Enclosure Fires

September 5, 2007
Author(s)
Rodney A. Bryant
The application of Stereoscopic Particle Image Velocimetry (SPIV) is a new approach to quantifying the ventilation in enclosure fires. SPIV is a non-intrusive optical measurement technique which measures the displacement of tracer particles in a flow. The

Cement and Concrete Materials Research at the National Institute of Standards and Technology (NIST)

September 5, 2007
Author(s)
Edward J. Garboczi, Dale P. Bentz, Jeffrey W. Bullard, Chiara F. Ferraris, Nicos Martys, Max A. Peltz, Sudalin Rodrigues, Paul E. Stutzman, Kenneth A. Snyder, John A. Winpigler
The materials science of cement and concrete is the focus of the Inorganic Materials Group at the National Institute of Standards and Technology (NIST). These experimental and computational research efforts include component and finished materials

Custom Hardware to Eliminate Bottlenecks in QKD Throughput Performance

September 5, 2007
Author(s)
Alan Mink
The National Institute of Standards and Technology (NIST) high-speed quantum key distribution (QKD) system was designed to include custom hardware to support the generation and management of gigabit data streams. As our photonics improved our software

Emergency Egress Strategies for Buildings

September 5, 2007
Author(s)
Richard W. Bukowski
The primary strategy for providing for the safety of building occupants in emergencies (especially fires) is by facilitating their relocation to a safe place. In other than a few institutional occupancies (health care and detentional) this generally

Improving Survivability in Motor Vehicle Fires

September 5, 2007
Author(s)
Ken H. Digges, Richard Gann, Steve J. Grayson, Marcelo M. Hirschler, Richard E. Lyon, David A. Purser, Jim G. Quintiere, Rody R. Stephenson, Archie Tewarson
Automobile fires are consistently among the largest causes of fire deaths in the United States and the U.S. motor vehicle industry has spent $14 million over the last ten years studying this problem. The authors of this review have analyzed the auto

Microwave Spectra of Molecules of Astrophysical Interest: XXV. Methylamine

September 5, 2007
Author(s)
Vadim V. Ilyushin, Francis J. Lovas
The microwave spectrum of methylamine in its ground vibrational state is critically reviewed and supplemented with spectral frequency calculations derived from rotation-internal rotation-inversion analysis. The review covers frequency range from 1 GHz to

Modeling Polymer Melt Flow Using the Particle Finite Element Method

September 5, 2007
Author(s)
Kathryn M. Butler, E Onate, S R. Idelsohn, R Rossi
A new particle-based approach is applied to the modeling of experiments on the effects of the melt flow behavior of thermoplastics. The Particle Finite Element Method (PFEM) combines convection of particles by the flow field with a finite element solution

Chip-level Security for RFID Smart Cards and Tags

September 4, 2007
Author(s)
Dylan Williams, Kate Remley
This report on RFID chip-level security is written to help both technical and non-technical audiences navigate the complex chip-level security features of RFID smart cards and tags, and make intelligent security choices. The report explores both attacks

Polarization-dependent optical 2D Fourier transform spectroscopy of semiconductors

September 4, 2007
Author(s)
T Zhang, Irina Kuznetsova, T. Meier, X. Li, Richard Mirin, P. Thomas, Steven T. Cundiff
Optical 2D Fourier transform spectroscopy (2DFTS) provides insight into the many-body interactions in direct gap semiconductors by separating the contributions to the coherent nonlinear optical response. We demonstrate these features of optical 2DFTS by

Tracing Electronic Pathways in Molecules Using Inelastic Tunneling Spectroscopy

September 4, 2007
Author(s)
Alessandro Troisi, J M. Beebe, Laura B. Picraux, Roger D. van Zee, D R. Stewart, M Ratner, James G. Kushmerick
Using inelastic electron tunneling spectroscopy (IETS) to measure the vibronic structure of non-equilibrium molecular transport, aided by a quantitative interpretation scheme based on non-equilibrium Greens function/density functional theory methods, we

A Hyperspectral Image Projector for Hyperspectral Imagers

September 3, 2007
Author(s)
Joseph P. Rice, Steven W. Brown, Jorge E. Neira, Robert R. Bousquet
We have developed and demonstrated a Hyperspectral Image Projector (HIP) intended for system-level validation testing of hyperspectral imagers, including the instrument and any associated spectral unmixing algorithms. HIP, based on the same digital

A Novel Model-Based Indoor Positioning Using Signal Strength

September 3, 2007
Author(s)
Kamran Sayrafian, D Kaspar
A simple technique to estimate the position of a mobile node inside a building is based on the Received Signal Strength (RSS). In a previous publication, we investigated the feasibility of using circular array antennas and beamforming in order to enable an
