Overview of the NIST Open Keyword Search 2013 Evaluation Worksho

August 23, 2013
Author(s)
Jonathan G. Fiscus, Nancy Chen
The NIST Open Keyword Search 2013 (OpenKWS13) Evaluation Workshop was the culmination of the first in a series of community-wide evaluations to test research systems that search for keywords in audio of a "surprise" language. OpenKWS13 made use of the

Better Defining the Uncertainties for the AGA-8 Equation

August 22, 2013
Author(s)
Eric W. Lemmon
In order to revise the AGA-8 documentation for publication in 2014, better knowledge of the 0.1% uncertainty level in the equation of state is needed. A 0.1% uncertainty level has been identified by an AGA-8 task group as the acceptable limit of error for

Author(s)
Elizabeth B. Lennon
This ITL Bulletin summarizes a new ITL publication, NIST Special Publication 800- 83 Revision 1,Guide to Malware Incident Prevention and Handling for Desktops and Laptops,which gives receommendations for organizations to improve their malware incident

Photocurrent Mapping of 3D CdSe/CdTe Windowless Solar Cells

August 22, 2013
Author(s)
Carlos M. Hangarter, Ratan K. Debnath, Jong Y. Ha, M. E. Sahiner, C. J. Reehil, W. A. Manners, Daniel Josell
This paper details the use of scanning photocurrent microscopy to examine localized current collection efficiency of thin film photovoltaic devices with in-plane patterning at a submicrometer length scale. The devices are based upon two interdigitated comb

Interfacial Ferromagnetism in LaNiO 3 /CaMnO 3 Superlattices

August 21, 2013
Author(s)
A. J. Grutter, H. Yang, Brian Kirby, M. R. Fitzsimmons, J. A. Aguiar, N. D. Browning, C. A. Jenkins, E. Arenholz, V. V. Mehta, U. S. Alaan, Y. Suzuki
We observe interfacial ferromagnetism in superlattices of the paramagnetic metal LaNiO 3 and the antiferromagnetic insulator CaMnO 3. The magnetic behavior can be explained in terms of an interfacial double exchange mechanism in which itinerant electrons

Feature Information Model for Disassembly

August 20, 2013
Author(s)
Shaw C. Feng
As sustainability becomes an important issue nowadays, disassembly becomes one of the key processes to turn out-of-service products into new or rebuilt products to save energy and materials. A disassembly process includes many subprocesses, such as

Model Based Enterprise Technical Data Package Requirements

August 20, 2013
Author(s)
Simon P. Frechette, Paul J. Huang
The Department of Defense and the National Institute of Standards and Technology held a Model Based Enterprise Summit and Technical Data Package (TDP) Workshop December 15-17, 2009 in Gaithersburg, MD. The TDP workshop gathered subject matter experts to

Modeling the Fatigue Crack Growth of X100 Pipeline Steel in Gaseous Hydrogen

August 20, 2013
Author(s)
Robert L. Amaro, Neha N. Rustagi, Andrew J. Slifka, Elizabeth S. Drexler, Kip Findley
Hydrogen is likely to play a key role (worldwide) in a future clean energy economy. Although pipeline transmission appears to be the most economical means to transport gaseous hydrogen, fundamental understanding of the deleterious effects of hydrogen on

Biology and Genetics of New Autosomal STR Loci Useful for Forensic DNA Analysis

August 19, 2013
Author(s)
John M. Butler, Carolyn R. Steffen
Short tandem repeats (STRs) are regions of tandemly repeated DNA segments found throughout the human genome that vary in length (through insertion, deletion, or mutation) with a core repeated DNA sequence. Forensic laboratories commonly use tetranucleotide

New Group-Contribution Approach to Thermochemical Properties of Organic Compounds: Hydrocarbons and Oxygen-Containing Compounds

August 19, 2013
Author(s)
Michael D. Frenkel, Sergey P. Verevkin, V N. Emel'yanenko, Robert D. Chirico, Vladimir Diky, Chris D. Muzny
A new group-contribution approach involving systematic corrections for 1,4-non-bonded carbon-carbon and carbon-oxygen interactions has been proposed. Limits of the applicability of the method, associated with the highly branched structures, were

Selected Procedures for Volumetric Calibrations (2013 Ed)

August 19, 2013
Author(s)
Georgia L. Harris
This publication contains Good Measurement Procedures (GMP), Good Laboratory Procedures (GLP), and Standard Operating Procedures (SOP) for use in calibration laboratories performing volumetric calibrations. This edition is updated from the 2012 version

The Cosmic Infrared Background Experiment (CIBER): the Narrow Band Spectrometer

August 19, 2013
Author(s)
Steven W. Brown, Keith R. Lykke, Allan W. Smith, P M. Korngut, T. Renbarger, T. Arai, J. Battle, A. Cooray, V. Hristov, B. Keating, M. G. Kims, A. Lanz, D. H. Lee, L. R. Levenson, P. Mason, T. Matsumoto, S. Matsuura, U. W. Niam, B. Shultz, I. Sullivan, K. Tsumura, T. Wada, M. Zemcov
We have developed a near-infrared spectrometer designed to measure the absolute intensity of the Solar 854.2 nm Ca II Fraunhofer line, scattered by interplanetary dust, in the Zodiacal light spectrum. Based on the known equivalent line width in the Solar

Effectively Control Negative Thermal Expansion of Single-phase Ferroelecrics of PbTiO 3 -(Bi,La)FeO 3 over a Giant Range

August 16, 2013
Author(s)
Jun Chen, Fangfang Wang, Qingzhen Huang, Lei Hu, Xiping Song, Jinxia Deng, Ranbo Yu, Xianran Xing
Control of negative thermal expansion is a fundamentally interesting topic in the negative thermal expansion materials in order for the future applications. However, it is a challenge to control the negative thermal expansion in individual pure materials

Space-Dependent Dynamics in 1,4-Polybutadiene Nanocomposite

August 16, 2013
Author(s)
J.H. Roh, Madhu Sudan Tyagi, T. E. Hogan, C. M. Roland
Neutron backscattering measurements were carried out on 1,4-polybutadiene, neat and bound to carbon nanoparticles. At large length scales (> 6Å), the Gaussian approximation holds: τ Β α ∝Q -2 where τ α is the segmental relaxation time, β the Kohlrausch
