Acoustic Attenuation in Fans and Ducts by Vaporization of Liquid Droplets [PDF]
, 1975 A cloud of small water droplets in saturated air attenuates acoustic disturbances by viscous drag, heat transfer, and vapor exchange with the ambient gas. The viscous and heat transfer phenomena attenuate at frequencies above 104 Hz for I-J.l droplets.

Effect of initial correlations on short-time decoherence
, 2002 We study the effect of initial correlations on the short-time decoherence of a particle linearly coupled to a bath of harmonic oscillators. We analytically evaluate the attenuation coefficient of a Schroedinger cat state both for a free and a ...
