Planar Resistors for Probe Station Calibration

December 1, 1992
Author(s)
Dave K. Walker, Dylan F. Williams, Nicole Morgan
This paper investigates the effects of variations in sheet resistance, geometry, distance from the probe tip, and fabrication processes on the impedance of planar nickel-chromium resistors. Resistor reactance is a strong function of film resistance, but

Reduction of Hydrogen Cyanide Concentrations and Acute Inhalation Toxicity From Flexible Polyurethane Foam Combustion Products by the Addition of Copper Compounds. Part 4. Effects of Combustion Conditions and Scaling on the Generation of Hydrogen cyanide

December 1, 1992
Author(s)
Barbara C. Levin, E Braun, M Paabo, Richard H. Harris Jr., Magdalena Navarro
Two full-scale protocols (A & B) were tested to determine the efficacy of cuprous oxide (Cu2O) in reducing the concentrations of hydrogen cyanide (HCN) from flexible polyurethane foams (FPU) when thermally decomposed under "realistic" room conditions. In

Toxic Potency Measurement for Fire Hazard Analysis. Technical Note.

December 1, 1992
Author(s)
V Babrauskas, B C. Levin, Richard G. Gann, M Paabo, Richard H. Harris Jr., Richard D. Peacock, S Yusa
A comprehensive methodology has been developed for obtaining and using smoke toxicity data for fire hazard analysis. This description of the methodology comprises: determination that the post-flashover fire is the proper focus of smoke inhalation deaths

Visibility of Exit Signs in Clear and Smoky Conditions

December 1, 1992
Author(s)
Belinda L. Collins, M S. Dahir, Daniel M. Madrzykowski
In the present study, the visibility of several types of internally lit exit signs was assessed under both clear and smoky conditions. In the evaluation both photometric and psychophysical measures were taken.

Flow of microemulsions through microscopic pores

November 15, 1992
Author(s)
Dean Ripple, Robert Berg
The flow of the microemulsion dioctylsulfosuccinate (AOT)/decane/water through 0.1 and 1.0 um diameter pores was studied for water droplet volume fractions ranging from 0 to 0.5. The viscosity of these microemulsions, as measured in a capillary viscometer

Nd:LiTaO 3 Waveguide Laser

November 15, 1992
Author(s)
Norman Sanford, J. A. Aust, K. J. Malone, Donald R. Larson, Alexana Roshko

Assessing Federal and Commercial Information Security Needs (IT)

November 1, 1992
Author(s)
David F. Ferraiolo, D M. Gilbert, N Lynch
In a cooperative effort with government and industry, the National Institute of Standards and Technology (NIST) conducted a study to assess the current and future information technology (IT) security needs of the commercial, civil, and military sectors

Computer Model of the Smoldering Ignition of Furniture.

November 1, 1992
Author(s)
Henri E. Mitler, George Walton
This paper describes a user-friendly computer model, TMPSUB2. This model calculates the temperature field throughout a solid (but porous) substrate which can undergo exothermic pyrolysis, when it is exposed to an arbitrary (localized) heat flux which can
