Shear bands resulting from plastic deformation in cold-rolled Al88Y7Fe5 metallic glass were observed to display alternating density changes along their propagation direction. Electron-energy loss spectroscopy (EELS) was used investigate the volume plasmon energy losses and around shear bands. Energy shifts of peak centre width (FWHM) reflecting damping precisely determined within an accuracy a ...

Over the years, new methods have emerged in order to optimize installation of wind turbines distribution systems meet loads demand, reduce technical energy losses and avoid exceeding voltage limits system. In this context, an algorithm for optimal radial is presented here. The Genetic Algorithm Cuckoo Search are used as optimization and, calculate power flow, Sum Powers Method used, respecting ...
