Functional background of the Tsallis entropy:coarse-grained systems and kappa distribution functions
Functional background Tsallis entropy coarse-grained systems kappa distribution functions
font style='font-size:12px;'>
2009/11/13
The concept of the generalized entropy is analyzed, with the particular attention to the definition postulated by Tsallis [J. Stat. Phys. 52, 479 (1988)]. We show that the Tsallis entropy can be rigor...

Extending the Similarity Theory for Atmospheric Boundary Layers: Contribution from Background Stratification
Atmospheric boundary layer similarity theory turbulence stratification effects
font style='font-size:12px;'>
2009/6/10
The structure of the atmospheric boundary layer has traditionally been described using only surface fluxes and the Coriolis parameter. We review here the proposal of Kitaigorodskii (1988) and Kitaigor...
