Superconductors: An Emerging Power Technology

December 31, 2004
Author(s)
John (Jack) W. Ekin
Superconductors offer effectively zero resistance to the flow of electricity and thus have the potential to significantly reduce Joule energy losses in the distribution and utilization of electric power, as well as the size and weight of power generators

The Critical Value of NIST to the Worldwide Metrology Interoperability Effort

December 31, 2004
Author(s)
John A. Horst, R Waite
The uniqueness and importance of the role of NIST to the worldwide metrology interoperability effort is explained and defended. The highlights of accomplishments by NIST in support of metrology interoperability are recounted, followed by a brief history of

Using ontologies to aid navigation planning in autonomous vehicles

December 31, 2004
Author(s)
Craig I. Schlenoff, Stephen B. Balakirsky, M Uschold, R Provine, S Smith
This paper explores the hypothesis that ontologies can be used to improve the capabilities and performance of on-board rout planning for autonomous vehicles. We name a variety of general benefits that ontologies may provide, and list numerous specific ways

FORENSIC STUDY OF THE STEEL IN THE WORLD TRADE CENTER

December 30, 2004
Author(s)
Thomas A. Siewert, Joseph D. McColskey, Christopher N. McCowan, Frank W. Gayle, William E. Luecke, Stephen W. Banovic, Timothy J. Foecke, Richard J. Fields
In September of 2002, the National Institute of Standards and Technology began a two-year investigation into the World Trade Center (WTC) disaster of September 11, 2001. Now almost complete, the investigation addresses many aspects of the catastrophe, from

Chip-scale atomic magnetometer

December 27, 2004
Author(s)
P Schwindt, Svenja A. Knappe, V Shah, Leo W. Hollberg, John Kitching, Li-Anne Liew, John Moreland
Using the techniques of micro-electro-mechanical systems (MEMS), we have constructed a small, low-power magnetic sensor based on alkali atoms. By measuring the energy shift of the atoms' magnetic moment due to a magnetic field via a coherent population

Liposomes As Model Cellular Systems

December 21, 2004
Author(s)
Laurie E. Locascio, Wyatt N. Vreeland, Andreas Jahn, Michael Gaitan
The discovery that phospholipids spontaneously form fluid-filled bubbles when exposed to aqueous solution was first made by Alec Bangham in the early 1960's while studying the effects of phospholipids on blood clotting in the Babraham Institute in England

TRC Thermodynamic Tables - Non-Hydrocarbons, Supplement No. 92

December 20, 2004
Author(s)
Michael D. Frenkel
New table for butyl ethanoate containing the density for the real fluid at selected temperatures and pressures. New table for 1-methylethyl ethanoate containing the density for the real fluid at selected temperatures and pressures. New table for ethyl

Algorithm xxx: Airy Functions

December 15, 2004
Author(s)
Bruce R. Fabijonas, Daniel W. Lozier, Frank W. Olver
We present a Fortran 90 module which computes the solutions of Airy's differential equation, and their derivatives, both on the real line and in the complex plane. The computational methods are numerical integration of the differential equation and

Semiconductor Factory and Equipment Clock Synchronization for e-Manufacturing

December 15, 2004
Author(s)
Ya-Shian Li-Baboud, Brad Van Eck
This study describes the potential methods, challenges, and recommendations for addressing factory and equipment clock synchronization and time stamping. The report also discusses why these are critical to the industry as the upcoming generations of tools

STEP, XML, and UML: Complementary Technologies

December 15, 2004
Author(s)
Russell S. Peak, Joshua Lubell, Vijay Srinivasan, Stephen C. Waterbury
One important aspect of product lifecycle management (PLM)is the computer-sensible representation of product information. Over the past 15 years or so, several languages and technologies have emerged that vary in their emphasis and applicability for such

Transport coefficients of the Lennard-Jones model fluid. III. Bulk viscosity

December 15, 2004
Author(s)
Karsten Meier, Arno D. Laesecke, Stephan Kabelac
In an extensive computer simulation study, the transport coefficients of the Lennard-Jones model fluid were determined with high accuracy from equilibrium molecular dynamics simulations. In the frame of time-correlation function theory, the generalized
