Thermodynamic Properties of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone: Vapor Pressure, (p, ?, T) Behavior, and Speed of Sound Measurements, and Equation of State

Mark O. McLinden, Richard A. Perkins, Eric W. Lemmon, Tara J. Fortin
We report comprehensive thermodynamic property measurements of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone. The p–ρ–T behavior was measured from T = (225 to 470) K with pressures up to 36 MPa using a two-sinker densimeter. These

240 Hz linewidth Brillouin laser from a microrod whispering gallery mode resonator

William Loh, Aurelien C. Coillet, Frederick N. Baynes, Scott B. Papp, Scott A. Diddams, Joe Becker
We demonstrate an ultra-low noise laser that oscillates based on the stimulated Brillouin scattering nonlinearity in an optical microresonator. Our Brillouin laser employs a microrod resonator whose larger mode volume compared to conventional resonators

Impact of Electricity Tariff Parameters on Net Zero Home Cost of Energy

Real-Time Centralized Spectrum Monitoring: Feasibility, Architecture, and Latency

September 29, 2015
Author(s)
Michael R. Souryal, Mudumbai Ranganathan, John Mink, Naceur A. El Ouni
This paper describes the implementation and evaluation of a real-time, centralized spectrum monitoring and alert system. Such a system can be used to support emerging spectrum sharing solutions that use a centralized controller to mediate tiered access to
