Practical realisation of the kelvin by Johnson noise thermometry

February 15, 2024
Author(s)
Horst Rogalla, D Rod White, Jifeng Qu, Samuel P. Benz, Christof Gaiser, Weston L. Tew, Nathan Flowers-Jacobs, Kevin J. Coakley, Alessio Polarollo, Chiharu Urano
Johnson noise thermometry (JNT) is a purely electronic method of thermodynamic thermometry. In primary JNT, the temperature is inferred from a comparison of the Johnson noise voltage of a resistor at the unknown temperature with a pseudo-random noise

Capability in Rockwell C Scale Hardness

July 1, 2000
Author(s)
Walter S. Liggett Jr, Samuel R. Low III, David J. Pitchure, Jun-Feng Song
To determine the capability of a system for Rockwell C scale hardness, one must make test measurements, which can be planned and interpreted as explained in this paper. Uncertainty, which is one part of capability, is treated specifically, and product

Clean Agent Suppression of Energized Electrical Equipment Fires

January 1, 2009
Author(s)
Gregory T. Linteris
The NFPA 2001 standard on the use of clean agents for the suppression of fires arose from the phase-out of Halon 1301. Standard methods exists for specifying the amount of clean agent required for Class A and Class B fires, but the recommendation for Class
