The stability properties of a vortex lens are studied in the quasi geostrophic (QG) framework using the generalized stability theory.Optimal perturbations are obtained using a tangent linear QG model and its adjoint.Their fine-scale spatial structures are studied in details.Growth rates of optimal perturbations are shown to be extremely sensitive t
The end of fife (EoL) of new aircraft Hockey Skates - Intermediate - Elite panels made of Al-Li alloys in which the stringers and skin were joined, either by laser beam welding (LBW) or by friction stir welding (FSW), was investigated at the lab scale.Different cutting strategies, ranging from cutting only for size reduction to full separation of a
