Cetaceans evolved flippers that are unique in both size and shape probably due to selection pressures associated with foraging and body size. Flippers function as control surfaces for maneuverability and stability. Flippers of cetaceans and engineered hydrofoils are similar with streamlined cross-sections and wing-like planforms, which affect lift, drag and hydrodynamic efficiency. Scale models...

In this talk I present several models which turned out to be quite successful in reproducing the experimentally measured hadron spectra in nucleus-nucleus collisions. The discussed models use concepts borrowed from relativistic hydrodynamics but they do not include the complete time evolution of the system. For this reason, they may be called hydro-inspired (freeze-out) models. The measured par...

The accuracy of state-of-the-art global barotropic tide models is assessed using bottom pressure data, coastal tide gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and independent tracked satellite orbit perturbations. Tide models under review include empirical, purely hydrodynamic (“forward”), and assimilative dynamical, i.e., constrained by observations. Ten domin...
