Home Cooking Fire Mitigation: Technology Assessment. Final Report.

November 1, 2011
Author(s)
Joshua Dinaburg, Daniel T. Guttuk
Cooking related fires are a leading cause of U.S. fire loss. Beginning in the mid 1980's, the National Institute of Standards and Technology, Consumer Product Safety Commission, and the home appliance industry undertook a comprehensive review 1 of

Local Weak Ferromagnetism in Single-Crystalline Ferroelectric BiFeO 3

November 1, 2011
Author(s)
M. Ramazanoglu, M. Laver, William D. Ratcliff, Shannon M. Watson, Wangchun Chen, Andrew Jackson, Karunakar NMN Kothapalli, Seongsu Lee, S.- W. Cheong, V. Kiryukhin
Polarized small-angle neutron scattering studies of single-crystalline multiferroic BefeO 3 reveal a long-wavelength spin density wave generated by 1° spin canting of the spins out of the rotation plane of the antiferromagnetic cycloidal order. This

Mobile-App Addiction: Threat to Security?

November 1, 2011
Author(s)
George Hurlburt, Jeff Voas, Keith Miller
Giving individuals this kind of information processing power, along with unprecedented connectivity, might be the single most impressive technical achievement of the 21st century. Nobody knows what the full impact of this transformation will be, but it's

Modeling Produces Insight into Fire Behavior

November 1, 2011
Author(s)
Adam M. Barowy, Daniel M. Madrzykowski
The National Institute of Standards and Technology (NIST) is the leader in the development of computer-based fire models that simulate the movement of fire gases and heat through a building and estimate the response of various fire protection systems. NIST

Moments of the Truncated Complex Gaussian Distribution

November 1, 2011
Author(s)
Ryan J. Pirkl
We present arbitrary moments of the univariate and bivariate truncated complex Gaussian distribution. Using these moment expressions, we investigate the convergence of a particular infinite series of moments encountered in recent statistical analyses of

Pinhole X -ray camera photos of an ECR ion source plasma

November 1, 2011
Author(s)
Lawrence T. Hudson, Sandor Biri, E Takacs, R. Racz, J. Palinkas
A 70 micrometer pinhole and an X-ray CCD camera in single photon counting mode were used to obtain spatially and spectral resolved images of an electron cyclotron resonance (ECR) ion source generated plasma. The method has good spatial resolution as well

The Latest and Greatest NIST PCR-based DNA Profiling Standard: Updates and Status of Candidate Standard Reference Material (SRM) 2391c

November 1, 2011
Author(s)
Margaret C. Kline, Carolyn R. Steffen, Jamie L. Almeida, Erica L. Romsos, Michael D. Coble, John M. Butler
Standard Reference Material 2391c (SRM 2391c) PCR-based DNA Profiling Standard is the third renewal of this SRM, originally released in 1995. SRM 2391c consists of 6 candidate components labeled A through F. Components A through D are supplied as genomic

Tips and tools for digitizing a museum collection

November 1, 2011
Author(s)
Regina L. Avila, Susan A. Sanders, Keith R. Martin
This article is a "how to guide" for directing and managing a museum photography project. It is based on what the NIST Research Library learned as we went through the process of gathering and photographing museum objects, organizing the digital images, and

Verification of Noise-Parameter Measurements and Uncertainties

November 1, 2011
Author(s)
James P. Randa, Dazhen Gu, Dave K. Walker
We propose and implement verification methods for measurements of noise parameters of amplifiers and transistors. Because the verification rests on the comparison of different measurement results, it also serves as a test of the uncertainties. The

500 GHz - 750 GHz Rectangular-Waveguide Vector-Network-Analyzer Calibrations

October 31, 2011
Author(s)
Dylan F. Williams
We develop an uncertainty analysis that captures the dominant sources of measurement error in state-of-the-art rectangular-waveguide vector-network-analyzer measurements over the frequency range 500 GHz – 750 GHz. We use the analysis to assess thru-reflect

Integrating jQuery with the 3D Descriptive Markup of X3DOM

October 31, 2011
Author(s)
Sanford P. Ressler
This paper describes a number of techniques using jQuery to take advantage of the 3D descriptive markup implemented by X3DOM. X3DOM is a project of the Web3D Consortium, primarily being implemented by staff at Fraunhoffer IGD to provide 3D descriptive

Modeling and Analysis of Disproportionate Collapse of RC Structures

October 31, 2011
Author(s)
Yihai Bao, Hai S. Lew, S K. Kunnath
Collapse analyses of a 10-story reinforced concrete frame building are carried out to investigate the robustness of structural systems against column removal scenarios. Computationally efficient reduced models are developed and used in the analyses. The

A 750 mW, continuous-wave, solid-state laser source at 313 nm for cooling and manipulating trapped 9Be+ ions

October 28, 2011
Author(s)
Andrew C. Wilson, Christian Ospelkaus, Aaron Vandevender, J. A. Mlynek, Kenton R. Brown, Dietrich G. Leibfried, David J. Wineland
We present a solid-state laser system that generates 750 mW of continuous-wave, single frequency, output at 313 nm. Sum-frequency generation with fiber lasers at 1550 nm and 1051 nm produces up to 2 W at 626 nm. This visible light is then converted to UV
