Fernando L. Podio, J S. Dunn
¿¿¿The Biometric Consortium Conference examines rapid advances in biometric technologies and applications and explores new developments in the areas of metrology, assurance, and standards. The Conference proceedings include presentations in a series of

Prototype Implementation of an Automated Structural Steel Tracking System

September 1, 2002
Author(s)
K M. Furlani, D T. Latimer, David E. Gilsinn, Alan M. Lytle
This paper discusses the prototype implementation of a system developed by researchers at the National Institute of Standards and Technology (NIST) for the transfer of real-time on-site metrology and metrology-based data for tracking steel frame

Reconstructing Images of Bar Codes for Construction Site Object Recognition

September 1, 2002
Author(s)
David E. Gilsinn, Geraldine S. Cheok, Dianne M. O'Leary
This paper discusses a general approach to reconstructing ground truth intensity images of bar codes that have been distorted by LADARoptics. The first part of this paper describes the experimental data collection of several bar code images along with

Report of the NIST Workshop on Automated Steel Construction

September 1, 2002
Author(s)
Alan M. Lytle, Kamel S. Saidi, William C. Stone, John L. Gross
The Building and Fire Research Laboratory of the National Institute of Standards and Technology, in cooperation with the American Institute of Steel Construction, sponsored a workshop on automated steel construction. The purpose of the workshop was to

Review of Traceable Temperatures and Temperature Measurement

September 1, 2002
Author(s)
Dean C. Ripple
Traceable Temperatures outlines the most common methods of measuring temperature and teaches the reader practical skills in assuring that those measurements are made with confidence at a known level of uncertainty. For a beginning user of thermometers or

Security Guide for Interconnecting Information Technology Systems

September 1, 2002
Author(s)
Timothy Grance, Joan Hash, Steven Peck, Jonathan Smith, Karen Korow-Diks
The Security Guide for Interconnecting Information Technology Systems provides guidance for planning, establishing, maintaining, & terminating interconnections between information technology (IT) systems that are owned & operated by different organizations

Self-Organization of Supramolecular Helical Dendrimers Into Complex Electronic Materials

September 1, 2002
Author(s)
Virgil Percec, A Rapp, Hans -. Spiess, Steven Hudson, H Duan, M Glodde, T K. Bera, Y Miura, I Shiyanovskaya, K D. Singer, V S. Balagurusamy, Paul A. Heiney, I Schnell
The discovery of electrical conduction in organic crystals and polymers has widened the range of potential optoelectronics materials, provided these exhibit sufficiently high charge carrier mobilities and are easy to make and process. Organic single

Spin-Current Induced Magnetotransport in Co/Cu/Co Nanostructures

September 1, 2002
Author(s)
Fred B. Mancoff, Stephen E. Russek
We report measurements on sub-100 nm current-perpendicular-to-place Co/Cu/Co spin-valves. The giant magnetoresistance versus applied magnetic field shows the switching in individual patterned Co nanomagnets. Spin transfer from the spin-polarized current to

Technical Digest Symposium on Optical Fiber Measurements, 2002

September 1, 2002
Author(s)
Paul A. Williams, Gordon W. Day
This digest contains the papers presented at the 2002 Symposium on Optical Fiber Measurements, a 2-1/2 day forum devoted to measurements of fibers, integrated optics, components and systems. Topics covered include measurement of polarization-mode

Templating of Inorganic Nanoparticles by PAMAM/PEG Dendrimer-Star Polymers

September 1, 2002
Author(s)
R C. Hedden, Barry J. Bauer, A P. Smith, Franziska Grohn, Eric J. Amis
Star polymers with a narrow distribution of sizes were labeled with fluorescent CdS nanoparticles, creating a new class of fluorescent probe molecules. Highly branched star polymers were prepared by attachment of poly(ethylene glycol) (PEG) arms to poly

Terrain Aided Localization of Autonomous Vehicles

September 1, 2002
Author(s)
Rajmohan Madhavan
This paper describes the development of a terrain-aided localization framework for autonomous land vehicles operating at high speeds in unstructured, expansive and harsh environments. The localization framework developed is sufficiently generic to be used

The Flying Carpet: A Tool to Improve Ship Repair Efficiency

September 1, 2002
Author(s)
Roger V. Bostelman, William P. Shackleford, Frederick M. Proctor, James S. Albus, Alan M. Lytle
NIST is working directly with industry to improve repair and conversion operations of ships in dry dock. The technology discussed is applicable to shipbuilding, aircraft maintenance, construction, and other industries requiring worker-access to large

Thermal and Flammability Properties of Polypropylene-Carbon Nanotube Composites

September 1, 2002
Author(s)
Takashi Kashiwagi, E A. Grulke, J N. Hilding, Richard H. Harris Jr., W H. Awad, Jack F. Douglas
Nanocomposites based on polypropylene and carbon nanotubes (up to 2 vol.-%) were melt blended, yielding good dispersion of the nanotubes without using any organic treatment or additional additives. Carbon nanotubes enhance the thermal stability of

Threshold Resonance Spectroscopy: A Key to Cold Collision Physics

September 1, 2002
Author(s)
Paul S. Julienne
Threshold scattering resonances play a crucial role in cold collision physics and cold molecule formation from cold atoms. We describe several examples involving magnetic Feshbach spectroscopy of Cs atoms, photoassociation of Na atoms in a Bose-Einstein
