Frequency of Lost Dogs and Cats in the United States and the Methods Used to Locate Them [PDF]
, 2012 Dogs and cats are a common member of the family in homes across the US. No population-based data exist on the frequency of pets getting lost from the home and lost pets can be a source of human and animal suffering. Our primary objective was to determine

A new method to identify the optimal temperature of latent-heat thermal-energy storage systems for power generation from waste heat [PDF]
, 2020 The integration of thermal-energy storage (TES) within waste-heat recovery power generation systems has the potential to improve energy-efficiency in many industrial processes with variable and/or intermittent waste-heat streams.

Cascaded structures for blind source recovery [PDF]
The 2002 45th Midwest Symposium on Circuits and Systems, 2002. MWSCAS-2002., 2003 Blind Source Recovery (BSR) is an interesting autonomous and unsupervised stochastic adaptation problem that includes the well-known blind adaptive problems of Blind Source Separation (BSS), Deconvolution (BSD) and Equalization (BSE). BSR includes also the nonlinear case and hence focuses on reproducing or estimating the source signals even if ...
