Epitaxial growth of rhenium with sputtering

October 6, 2005
Author(s)
Seongshik Oh, Dustin P. Hite, Katarina Cicak, Kevin Osborn, Raymond W. Simmonds, Robert Mcdermott, Ken B. Cooper, Matthias Steffen, John M. Martinis, David P. Pappas
We have grown epitaxial renium (0001) films on α-Al 2O 3(0001) substrates using sputter deposition in an ultra high vacuum system. We find that better epitaxy is achieved with DC rather than with RF sputtering. With DC sputtering, epitaxy is obtained with

CCQM K40 DETERMINATION OF PCB CONGENERS IN SOLUTION: FINAL REPORT

October 5, 2005
Author(s)
David L. Duewer, Willie E. May, Reenie M. Parris, Michele M. Schantz, Stephen A. Wise
Abstract. Solutions of known mass fraction of organic analytes of interest are typically used to calibrate the measurement processes used in the determination of these analytes. Appropriate value assignments and uncertainty calculations for these

High Speed Fiber-Based Quantum Key Distribution using Polarization Encoding

October 5, 2005
Author(s)
Xiao Tang, Lijun Ma, Alan Mink, Anastase Nakassis, Barry J. Hershman, Joshua Bienfang, Ronald Boisvert, Charles W. Clark, Carl J. Williams, A Gross, E Hagley, J Wen
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Infrared Emittance Measurements at NIST

October 5, 2005
Author(s)
Leonard M. Hanssen, Benjamin K. Tsai, Sergey Mekhontsev
A new capability for the measurement of the temperature-dependent emittance of specular samples in the near infrared spectral region has been developed in NIST s Infrared Spectrophotometry Laboratory to provide emittance measurements and standards for a

Low Temperature Calorimetry Studies of Hydrating Portland Cement Pastes

October 5, 2005
Author(s)
Dale P. Bentz
This report presents nearly 200 low temperature calorimetry (LTC) scans performed on hydrating portland cement pastes between 2002 and 2005. Because the LTC scans provide valuable information on the percolation of various size pore networks within the

Fragility of Glass-Forming Polymer Liquids

October 4, 2005
Author(s)
J Dudowicz, Karl Freed, Jack F. Douglas
Many fluids exhibiting complex molecular structure or interactions solidify by glass-formation rather than crystallization. This tendency is especially prevalent in polymeric and biological systems where glass-formation is normal rather than exceptional

IT: The Thirteenth Text Retrieval Conference, TREC 2004

October 3, 2005
Author(s)
Ellen M. Voorhees
This report provides an overview of the thirteenth Text Retrieval Conference, TREC 2004. TREC 2004 was held at the National Institute of Standards and Technology (NIST) November~16--19, 2004. The conference was co-sponsored by NIST, the US Department of

Overview of the TREC 2004 Terabyte Track

October 3, 2005
Author(s)
Charles L. Clarke, Nick Craswell, Ian Soboroff
The Terabyte Track explores how adhoc retrieval and evaluationtechniques can scale to terabyte-sized collections. For TREC 2004, ourfirst year, 50 new adhoc topics were created and evaluated over a426GB collection of 25 million documents taken from the

Lessons Learned in Wireless Monitoring

October 2, 2005
Author(s)
William M. Healy
The emergence of wireless communications technology has led to an increasing interest in sensors that are free from wiring constraints that increase the cost of installation of a sensor network and create a confusing collection of wires in a building. In

A Cross-Correlation Based Method for Spatial-Temporal Traffic Analysis

October 1, 2005
Author(s)
Kevin L. Mills, Y. L. Jiang
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

A Diner's Guide to Evaluating a Framework for Ubiquitous Computing Applications

October 1, 2005
Author(s)
Mary F. Theofanos, Jean C. Scholtz
There is a clear need for evaluation methodologies specifically suited to ubiquitous computing applications. Here we investigate a user evaluation framework we proposed earlier which draws upon traditional desktop methods, but carefully adapts them based

A Model-Based Analysis of First-Generation Service Discovery Systems

October 1, 2005
Author(s)
Christopher E. Dabrowski, Kevin L. Mills, Stephen Quirolgico
Future commercial software systems will be based on distributed service-oriented architectures in which applications are composed dynamically from remote components. A key part of service-oriented computing is the ability for clients to discover remote

A Questionnaire to Assess the Difficulty of Open Source Analysis Taskings

October 1, 2005
Author(s)
T T. Hewett, Jean C. Scholtz
Our goal is to produce metrics for assessing the impact of software tools and environments produced for the intelligence community. To this end we are developing a task difficulty questionnaire to attempt to identify and assess the impact of task

A Tool Kit to Generate 3D Animated CAESAR Bodies

October 1, 2005
Author(s)
Quandou (. Wang, Sanford P. Ressler
The Civilian American and European Surface Anthropometry Resource (CAESAR) database provides a comprehensive source for body measurement in numerous industries such as apparel, aerospace, and automobile. Generating animated CAESAR body sequences from still
