Introductory Remarks (NISTIR 5766)

November 1, 1995
Author(s)
Jiann C. Yang
Objectives of the Workshop: (1) to identify what we know and don't know in gas generator technology for fire suppression; (2) to identify future research areas in gas generator technology for fire suppression; (3) to identify potential users and address

Measurement of the self-broadening rate coefficients of the cesium resonance lines

November 1, 1995
Author(s)
Zeina J. Kubarych, J Huennekens, R K. Namiotka, J Sagle
The self-broadening rate coefficients of the cesium D1 [62S1/2 - 62P1/2] and D2 [62S1/2 - 62P3/2] resonance lines are determined from the 62P1/2 --> 62D3/2, 62D3/2---> 72D3/2 and 62P3/2 --> 72D5/2 transition lineshapes, which are mapped out using single

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
