Motion-Model-Based Boundary Extraction

November 1, 1995
Author(s)
H Liu, Tsai H. Hong, Martin Herman, Rama Chellappa
Motion boundary extraction and optical flow computation are two subproblems of the motion recovery problem that cannot be solved independently of each other. They represent the most common dilemma in motion research. A popular approach uses an iterative

Optimization of System Discharge (NIST SP 890)

November 1, 1995
Author(s)
Jiann C. Yang, Thomas G. Cleary, I Vazquez, C I. Boyer, M D. King, B D. Breuel, C A. Womeldorf, William L. Grosshandler, Marcia L. Huber, L Weber, G. Gmurczyk
Current aircraft fire suppression bottles for dry bay and engine nacelle applications, which are designed to meet Military Specification MIL-C-22284A (proof pressure of 9.62 MPa and minimum burst pressure of 12.37 MPa), are normally filled with liquid

Optoelectronics at NIST

November 1, 1995
Author(s)
Gordon W. Day
This document contains summaries of projects at NIST in which optoelectronics plays an important role. The document is intended to encourage more coordination and collaboration among NIST researchers in the field and more efficient use of NIST resources

Photodegradation of CF3I (NIST SP 890)

November 1, 1995
Author(s)
Marc R. Nyden
CF3I has been identified as a leading candidate for the replacement of halon fire extinguishing agents because of its high degree of effectiveness as a flame suppressant and its short tropospheric lifetime and low ozone depeletion potential. Although this

Prediction of HF Formation During Suppression (NIST SP 890)

November 1, 1995
Author(s)
Gregory T. Linteris, G. Gmurczyk
The acid gases hydrogen fluoride, hydrogen chloride, and hydrogen bromide (HX, where X denotes a halogen), are thought to be the most damaging and dangerous of the potential decomposition products, and much study has been devoted to determining the amounts

Real-Time Suppressant Concentration Measurement (NIST SP 890)

November 1, 1995
Author(s)
William M. Pitts, George W. Mulholland, B D. Breuel, Erik L. Johnsson, S Chung, Richard H. Harris Jr., D E. Hess
The development and testing of two approaches for recording real-time measurements (millisecond time resolution) of concentration for halon alternatives are summarized. Discussions of the background necessary to understand their operation is included. The

Solid Propellant Gas Generators: Proceedings of the 1995 Workshop (NISTIR 5766)

November 1, 1995
Author(s)
Jiann C. Yang, William L. Grosshandler
A workshop on solid propellant gas generators was held on June 28-29, 1995 at the National Institute of Standards and Technology under the sponsorship of the Building and Fire Research Laboratory. Gas generator technology was first proposed as alternative

Species Concentration Measurements (NISTIR 5766)

November 1, 1995
Author(s)
William M. Pitts
The objective if this effort is to evaluate possible methods for real-time measurements of concentrations of alternative fire extinguishing agents for dry-bay and nacelle fire applications. If one or more feasible approaches are identified early in the

Suppression of Engine Nacelle Fires (NIST SP 890)

November 1, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary, P. Borthwick, N Gorchkov, Kevin B. McGrattan, Glenn P. Forney, William L. Grosshandler, Cary Presser, L Melton
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

Test of a Slow Off-Axis Parabola at it

November 1, 1995
Author(s)
R E. Parks, Christopher J. Evans, Lianzhen Shao
We describe the interferometric testing of a slow (f/16 at the center of curvature) off-axis parabola, intended for use in an x-ray spectrometer, that uses a spherical wave front matched to the mean radius of the asphere. We find the figure error in the
