Multiscale Mesoscopic Entropy of Driven Macroscopic Systems [PDF]
Entropy, 2013 How do macroscopic systems react to imposed external forces? Attempts to answer this question by a general principle have a long history. The general feeling is that the macroscopic systems in their reaction to imposed external forces follow some kind of optimization strategy in which their internal structure is changed so that they offer the least ...
