Experiences in Deploying Test Arenas for Mobile Autonomous Robots

September 4, 2001
Author(s)
Adam S. Jacoff, Elena R. Messina, John Evans
The National Institute of Standards and Technology has created a set of reference test arenas for evaluating the performance of mobile autonomous robots performing urban search and rescue tasks. The arenas are intended to help accelerate the robotic

Appendix: Auditory Diagnostic and Prosthetic Devices

September 3, 2001
Author(s)
Victor Nedzelnitsky
This paper is an appendix for the proceedings of the Workshop on Biomedical Materials and Devices, held June 13 -14, 2001. The workshop is part of a series of workshops and topical meetings organized by NIST in the area of biomedical technology. The

Overview of the TREC-9 Question Answering Track

September 3, 2001
Author(s)
Ellen M. Voorhees
The TREC question answering track is an effort to bring the benefits of large-scale evaluation to bear on the question answering problem. The track has run twice so far, where the goal both times was to retrieve small snippets of text that contain the

An Uncertainty Analysis of the High-Speed Pulse Parameter Measurements at NIST

September 1, 2001
Author(s)
Nicholas Paulter, Donald R. Larson
A detailed uncertainty analysis for NIST's pulse parameter measurement service is presented that represents the new pulse parameter measurement and extraction processes. Uncertainties for pulse amplitude, transition duration, overshoot, and under(pre)shoot

Core-Hole-Electron Interaction in X-Ray Raman Scattering

September 1, 2001
Author(s)
J A. Soininen, K Hamalainen, W A. Caliebe, C C. Kao, Eric L. Shirley
This work applies a recently developed first-principles scheme for calculating core-excited states in solids tonon-resonant inelastic x-ray scattering. Within the computational scheme the interaction between the excited electron and the core hole is

Distribution and Retention of 137 Cs in Sediments at the Hanford Site, Washington

September 1, 2001
Author(s)
J P. McKinley, Cynthia J. Zeissler, J M. Zachara, R J. Serne, Richard M. Lindstrom, H T. Schaef, R D. Orr
sium-137 and other contaminants have leaked from many of the single-shell storage tanks at the Hanford Site in southeastern Washington. The leakage was into sandy unconsolidated sediments consisting largely of quartz, plagioclase, micas, smectite, and

Dynamics of Photoinduced Collisions of Cold Atoms Probed with Picosecond Laser Pulses

September 1, 2001
Author(s)
F K. Fatemi, Kevin Jones, H Wang, I Walmsley, Paul D. Lett
Pump-probe experiments are performed in which cold colliding Na atoms are photoassociated to form Na$ _(2)$ molecules, and subsequently ionized. the experiments are performed in a regime where the pulsed photoassociation to an intermediate potential takes
