Electromagnetically induced transparency in a superconducting three-level system

April 16, 2009
Author(s)
Mika Sillanpaa, Katarina Cicak, Fabio Altomare, Jae Park, Raymond Simmonds, Jian Li, G. S. Paraoanu, Pertti Hakonen
… When a three-level quantum system is irradiated by an intense coupling field … the population is trapped in the ground state, is known in quantum optics as electromagnetically induced transparency . … can be considered an artificial atom with a multilevel quantum structure. These observations are qualitatively …

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

Comments on the Discrete Variable Representation

October 16, 2008
Author(s)
B I. Schneider, N Nygaard
We discuss the application of the Discrete Variable Representation to Schr dinger problems which involve singular Hamiltonians. Unlike recent authors who invoke transformations to rid the eigenvalue equation of singularities at the cost of added complexity

Evaluation of a Modified Void Descriptor Function to Uniquely Characterize Pore Networks and Predict Fracture Location in Additively Manufactured Metals

November 15, 2021
Author(s)
Dillon Watring, Jake Benzing, Orion Kafka, Li-Anne Liew, Newell Moser, John Erickson, Nik Hrabe, Ashley Spear
Variations in additive manufacturing (AM) processing parameters can lead to variations in porosity, making it challenging to predict pore- or void-sensitive mechanical response in AM metals. A recently developed pore metric, the void descriptor function

Particle shape effects on particle size measurement for crushed waste glass

December 18, 2016
Author(s)
Kyle Riding, Mohammadreza Mirzohosseini, Edward Garboczi
Recently, narrow particle size distributions, as measured by sieve analysis, of crushed waste glass were used as a replacement for Portland cement in concrete. Their chemical reactivity was successfully studied as a function of this measure of particle
