Assessing Halon Alternatives for Aircraft Engine Nacelle Fire Suppression.

May 1, 1995
Author(s)
William L. Grosshandler, Cary Presser, Daniel L. Lowe, William J. Rinkinen
A coaxial turbulent spray burner was built to evaluate the relative effectiveness of different chemicals for suppressing fires in a jet engine nacelle. The fire suppressant of current choice, halon 1301 (CF3Br), must be replaced because of its detrimental

Broadband Permittivity Measurements of Thin-Film Ferroelectrics to 40 GHz

February 25, 2008
Author(s)
Nathan D. Orloff, James C. Booth, Makoto Murakami, Ichiro Takeuchi
We demonstrate a novel experimental technique to measure the complex permittivity function of dielectric thin films over the frequency range from 100 Hz to 40 GHz. We apply this technique to determine the broadband permittivity function for ferroelectric

Efficient Algorithms for T-way Test Sequence Generation

October 16, 2012
Author(s)
Linbin Yu, Yu Lei, Raghu N. Kacker, D. Richard Kuhn, James F. Lawrence
Combinatorial testing has been shown to be a very effective testing strategy. Most work on combinatorial testing focuses on t-way test data generation, where each test is an unordered set of parameter values. In this paper, we study the problem of t-way

Achieving Intelligent Performance in Autonomous On-Road Driving

October 1, 2004
Author(s)
Craig I. Schlenoff, J L. Evans, Anthony J. Barbera, James S. Albus, Elena R. Messina, Stephen B. Balakirsky
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 state-of-the-art in

Performance Evaluation of Road Detection and Following Systems

October 1, 2004
Author(s)
Tsai Hong Hong, A Takeucki, Mike Foedisch, 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

Task Analysis of Autonomous On-Road Driving

October 1, 2004
Author(s)
Anthony J. 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

Reflectance Calibration Standard for Optical Discs

January 1, 2002
Author(s)
Xiao Tang, Jian Zheng
An accurate method for the determination of reflectance of reference discs has been developed at NIST. The discs can be used as a traceable industry standard in the calibration of optical disc testing equipment.

Field Demonstration of Laser Scanning for Excavation Measurement

October 1, 2000
Author(s)
Geraldine S. Cheok, Robert R. Lipman, Christoph J. Witzgall, Javier Bernal, William C. Stone
The use of a scanning laser to measure terrain changes due to excavation at a construction site is described. The objective at this phase of the project is to develop the tools necessary to measure terrain changes in real-time. This paper focuses on
