Apparatus for Screening Fire Suppression Efficiency of Dispersed Liquid Agents.

January 1, 2001
Author(s)
Jiann C. Yang, Michelle K. Donnelly, N C. Prive, William L. Grosshandler
This paper is an abridged version of NISTIR 6319. The design, construction, demonstration, and operation of a bench-scale device capable of screening the fire suppression efficiency of liquid agents are described in detail in this report. The apparatus is

Aspects of Practical Radiometry: Terminology, Uncertainty, and Physical Optics

January 1, 2001
Author(s)
Eric L. Shirley, Raju V. Datla
We discuss efforts that have been made to help establish-in practice-a greater uniformity of nomenclature used for various terms in radiometry as well as expression of measurement uncertainty. We also discuss the role of diffraction effects, which account

MotivationSemiconductor wafers and many types of optical elementsrequire ultra-smooth surfaces in order to functionas specifiedExamples:Laser gyro mirrors with rms roughness 0.1 nmSilicon gate oxides with thickness 3 nm,rms roughness must be significantly

Bayesian Approach to Combining Results From Multiple Methods

January 1, 2001
Author(s)
Hung-Kung Liu, Nien F. Zhang
Many solutions to the problem of estimating the consensus mean from the results of multiple methods or laboratories have been proposed. In a Bayesian analysis, the consensus mean is specified through probabilistic dependency as either a ¿parent¿ or a

Bias in the Introduction of Variation as an Orienting Factor in Evolution

January 1, 2001
Author(s)
L Y. Yampolsky, Arlin Stoltzfus
According to New Synthesis doctrine, the direction of evolution is determined by selection and not by internal causes that act by way of propensities of variation. This doctrine rests on the theoretical claim that because mutation rates are small in
