BACnet for Utilities and Metering

April 1, 2008
Author(s)
David G. Holmberg, Steven T. Bushby, James J. Butler
The BACnet standard has been expanded to include new object types that are intended for metering and demand management applications, as well as a web services specification that allows any outside service provider access to BAS data. Since the most common

CODATA recommended values of the fundamental physical constants: 2006

April 1, 2008
Author(s)
Peter J. Mohr, Barry N. Taylor, David B. Newell
The paper give the 2006 self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on data for Science and Technology (CODATA) for international use. Further, it describes in detail the

Collimated spin wave beam generated by a single layer, spin torque nanocontact

April 1, 2008
Author(s)
Mark Hoefer, Thomas J. Silva, M D. Stiles
A model of spin-torque-induced magnetization dynamics based on semiclassical spin diffusion theory for a single-layer nanocontact in presented. The model incorporates effects due to the current-induced Oersted field and predicts the generation of a variety

Computer Security Division 2007 Annual Report

April 1, 2008
Author(s)
Kevin Stine, Mark Wilson
Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry

Digital Forensics at the National Institute of Standards and Technology

April 1, 2008
Author(s)
James R. Lyle, Douglas R. White, Richard Ayers
There are three digital forensic science projects: National Software Reference Library (NSRL), Computer Forensic Tool Testing (CFTT), Computer Forensic Reference Data Sets (CFReDS) currently providing resources for the digital investigator underway at the

Energy Balance in a Large Compartment Fire

April 1, 2008
Author(s)
Anthony P. Hamins, Erik L. Johnsson, Alexander Maranghides
The National Institute of Standards and Technology (NIST) and the Nuclear Regulatory Commission (NRC) are collaborating to assess and validate fire computer codes for nuclear power plant applications. This evaluation is being conducted through a series of

Experimental Investigation of Firebrands: Generation and Ignition of Fuel Beds

April 1, 2008
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Alexander Maranghides, William E. Mell, Jiann C. Yang
A series of real scale fire experiments were performed to determine the size and mass distribution of firebrands generated from Douglas Fir (Pseudotsuga menziesii) trees. The results of the real scale fire experiments were used to determine firebrand sizes

Measurements to Support Modulated-Signal Radio Transmissions for the Public-Safety Sector

April 1, 2008
Author(s)
Catherine A. Remley, Galen H. Koepke, Christopher L. Holloway, Chriss A. Grosvenor, Dennis G. Camell, John M. Ladbury, Robert Johnk, David R. Novotny, William F. Young, George Hough, Michael McKinley, Yann Becquet, John Korsnes
We report on measurements of parameters utilized for characterization of broadband wireless technologies proposed for use by emergency responders (firefighters, police, and emergency medical personnel) and other public-safety personnel. We designed a

Mechanism for spontaneous growth of GaN nanowires with molecular beam epitaxy

April 1, 2008
Author(s)
Kristine A. Bertness, Alexana Roshko, Lorelle Mansfield, Todd E. Harvey, Norman A. Sanford
Although most semiconductor nanowires are grown via the vapor-liquid-solid mechanism, we present evidence that GaN nanowires form because of thermodynamically driven variations in surface sticking coefficients on different crystallographic planes under

Physical Properties of LnAg y X 4-y (Ln =La, Ce; X = Al, Ga; y 0.72)

April 1, 2008
Author(s)
Jung Y. Cho, Monica Moldovan, David P. Young, Nathan Lowhorn, Julia Y. Chan
Single crystals of LnAg(y)X(4-y) (Ln = La, Ce; X = Al, Ga; y 0.72) were synthesized by aluminum or gallium flux and characterized by single crystal X-ray diffraction. LnAg(y)X(4-y) (Ln = La, Ce; X = Al, Ga; y 0.72) crystallize in the tetragonal space group

Probing the dynamic fluorescence properties of single water-soluble quantum dots

April 1, 2008
Author(s)
J R. Krogmeier, Hyeong G. Kang, Matthew L. Clarke, p Yim, Jeeseong Hwang
The influence of surface modifications, including carboxyl-, amine-, and mercaptoundecanoicacid-functionalized chemistries, on the dynamic fluorescence properties of single quantum dots (QDs) are probed using a combined confocal fluorescence microscopy and
