Achieving intelligent performance in autonomous on-road driving

October 28, 2004
Author(s)
Craig I. Schlenoff, John Evans, Tony Barbera, James S. Albus, Elena R. Messina
This paper describes NIST?s efforts in evaluating what it will take to achieve autonomous human-level driving skills in terms of time and funding. NIST has approached this problem from several perspectives: considering the current stateof- the-art in

Performance evaluation of road detection and following algorithms

October 28, 2004
Author(s)
Tsai H. Hong, A Takeuchi, M Foedissch, Michael O. Shneier
We describe a methodology for evaluating algorithms to provide quantitative information about how well road detection and road following algorithms perform. The approach relies on generating a set of standard data sets annotated with ground truth. We

Power Balance in Highly Loaded Fluorescent Lamps

October 28, 2004
Author(s)
G G. Lister, John J. Curry, James E. Lawler
Discrepancies reported in the literature between numerical predictions and experimental measurements in low-pressure Hg discharges at high current densities are considered. A one-dimensional fluid model and recent spectroscopic and Langmuir probe

Status report on next generation LADAR for driving unmanned ground vehicles

October 28, 2004
Author(s)
Maris Juberts, Tony Barbera
The U.S. Department of Defense has initiated plans for the deployment of autonomous robotic vehicles in various tactical military operations starting in about seven years. Most of these missions will require the vehicles to drive autonomously over open

Task Analysis of Autonomous On-road Driving

October 28, 2004
Author(s)
Tony Barbera, John A. Horst, Craig I. Schlenoff, David Aha
The Real-time Control System (RCS) Methodology has evolved over a number of years as a technique to capture task knowledge and organize it into a framework conducive to implementation in computer control systems. The fundamental premise of this methodology

Dynamic and static magnetic anisotropy in thin-film cobalt zirconium tantalum

October 26, 2004
Author(s)
John P. Nibarger, R Ewasko, Michael Schneider, Thomas J. Silva
The magnetic anisotropy values of thin amorphous cobalt zirconium tantalum (CZT) films were determined from static and dynamic measurements. Dynamic techniques show a rotatable component of anisotropy that decreases with increasing longitudinal bias field

IT--The Twelfth Text Retrieval Conference, TREC 2003

October 25, 2004
Author(s)
Ellen M. Voorhees, Donna K. Harman
This chapter provides an executive summary of the TREC workshop series and the remainder of thevolume. It explains the motivation for TREC and highlights TREC's accomplishments in improving retrievaleffectiveness and fostering technology transfer.

Observation of Quantum Oscillations between a Josephson Phase Qubit and a Microscopic Resonator using Fast Readout

October 25, 2004
Author(s)
Ken Cooper, Matthias Steffen, Robert McDermott, Raymond Simmonds, Seongshik Oh, Dustin Hite, David P. Pappas, John M. Martinis
We have detected coherent quantum oscillations between Josephson phase qubits and microscopic critical current fluctuators by implementing a new state readout technique that is an order of magnitude faster than previous methods. The period of the

Mechanism of Dynamic NBTI of pMOSFETs

October 21, 2004
Author(s)
Baozhong Zhu, John S. Suehle, Joseph B. Berstein
A series of experiments are conducted to study the physical mechanism of reduced NBTI effects observed under pulsed bias conditions. A reduction of Vth and Ion is observed for pulse periods shorter than critical time constants that are believed to be

Dynamic behavior of dagger-shaped atomic force microscope cantilevers

October 20, 2004
Author(s)
K Shen, Donna C. Hurley, J Turner
Experimental techniques based on the atomic force microscope (AFM) have been developed for characterizing mechanical properties at the nanoscale and applied to a variety of materials and structures. Atomic force acoustic microscopy (AFAM) is one such

Validation of the Receprocity Law for Coating Photodegradation

October 20, 2004
Author(s)
Joannie W. Chin, Tinh Nguyen, Jonathan W. Martin, E Byrd
Accelerating the photodegradation of commerical polymeric materials has great practical importance in the weathering community. However, questions exist as to whether high radiant flux exposure results cn be extrapolated to in-service exposure levels
