Author(s)
Michael Sindelar
The National Software Reference Library (NSRL) of the U.S. National Institute of Standards and Technology (NIST) collects software from various sources and publishes file profiles computed from this software (such as MD5 and SHA-1 hashes) as a Reference

Thermodynamics of the Hydrolysis Reactions of Nitriles

July 1, 2005
Author(s)
Yadu D. Tewari, Robert N. Goldberg
Microcalorimetry and high-performance liquid chromatography (h.p.l.c) have been used to conduct a thermodynamic investigation of the following nitrilase catalyzed reactions: (1) benzonitrile(aq) + 2 H2O(l) = benzoic acid(aq) + ammonia(aq), (2)

Thin-film coatings: Carbon nanotube coatings promise better thermal detectors

July 1, 2005
Author(s)
John H. Lehman, Anne Dillon
With high thermal conductivity and resistance to damage, carbon nanotube coatings are a promising new technology for thermal detectors. NIST and NREL scientists are exploring this viable alternative with the aim of developing better radiometric standards

Towards Semantic-Based Supply Chain Integration

July 1, 2005
Author(s)
Nenad Ivezic, Nenad Anicic, Albert T. Jones, Zuran Marjanovic
We describe a novel Enterprise Application Integration (EAI) architecture based on existing B2B standards. We show how such an EAI architecture can use automated reasoning tools to provide application integration support and validation capabilities. We

Two Finger Matching with Vendor SDK Matchers

July 1, 2005
Author(s)
Craig I. Watson, Charles L. Wilson, Michael D. Indovina, Brian J. Cochran
This report is an extension of the NIST Studies of one-to-one Fingerprint Matching with Vendor SDK Matchers which evaluated the accuracy of SDK (Software Development Kit) based on COTS (Commercial Off-The-Shelf) fingerprint matching systems for one-to-one

Using X-Ray Topography to Inspect Surfaces of Single-Crystal Components

July 1, 2005
Author(s)
David R. Black
X-ray diffraction topography, which is sensitive to local strain and/or crystallographic orientation, provides a unique view of the surface of single-crystal samples and can be used to nondestructively inspect for surface and subsurface damage. The

X-Ray Topography Study of Surface Damage in Single-Crystal Sapphire

July 1, 2005
Author(s)
Robert S. Polvani, Kate Medicus
X-ray diffraction topography was used to investigate the relationship between sub-surface damage, near-surface microstructure, and fracture strength in a series of sapphire modulus of rupture (MOR) bars which had been fabricated to proof test fabrication

A Framework For Autonomy Levels For Unmanned Systems (ALFUS)

June 30, 2005
Author(s)
Hui-Min Huang, K Pavek, B Novak, James S. Albus, Elena R. Messina
We describe the construct of the framework for the Autonomy Levels of Unmanned Systems (ALFUS), including the ongoing development effort undertaken by the Ad Hoc working group. We describe the elements of the ALFUS framework and the process that we

Road Sign Detection and Recognition

June 30, 2005
Author(s)
Michael O. Shneier
Road sign detection is important to a robotic vehicle that automatically drives on roads. In this paper, road signs are detected by means of rules that restrict color and shape and require signs to appear only in limited regions in an image. They are then

Silicon Nanowires As Enhancement-mode Schottky-barrier Field-effect Transistors

June 29, 2005
Author(s)
Sang-Mo Koo, Monica D. Edelstein, Qiliang Li, Curt A. Richter, Eric M. Vogel
Silicon nanowire field-effect transistors (SiNWFETs) have been fabricated with a highly simplified integration scheme to function as Schottky barrier transistors and excellent enhancement-mode characteristics with high on/off current ratio 107 are

19th International Conference on Chemical Thermodynamics website

Author(s)
Marilyn R. Yetzbacher, Michael D. Frenkel
A website containing general information and registration instruction for the 19th International Conference on Chemical Thermodynamics to be held in Boulder from July 30 to August 4, 2006.

Low Jitter Metal Vapor Vacuum Arc Ion Source for EBIT Injections

June 27, 2005
Author(s)
G Holland, Craig N. Boyer, J Seely, Joseph N. Tan, Joshua M. Pomeroy, John D. Gillaspy
A metal vapor vacuum arc (MeVVA) ion source having eight different cathodes that are individually selectable via the control electronics and having low trigger jitter (200 ns) is described. The arc plasma is produced by means of a 26 kV, 125 A, 30 s pulse

U.S. Population Data for the Multi-Copy Y-STR Locus DYS464

June 25, 2005
Author(s)
John M. Butler, R Schoske
Population studies are important in forensic science and human identity testing to help demonstrate that STR markers are polymorphic and will help distinguish the various individuals from one another. A total of 679 male DNA samples from 3 U.S. populations

Ranking Interventions to Improve Inner-City Housing Indoor Air Quality
