The ultimate goal of power system operation and planning is to increase power system reliability which enforces interconnected operation of power system. As a result of power system interconnection, the inter-area oscillation under different disturbances may cause power system partial or total blackout. DC-segmentation of interconnected power systems is a solution in which the topology of the n...
in industries, preventive maintenance (pm) is not a new practice to minimise the sudden breakdown of production machine. pm will be performed at predetermine intervals to provide a balance between failure cost and component utilisation (aging). however, most of pm interval is based on experience or original equipment manufacturer (oem) recommendations. consequently, the benefits from pm are not...
We measured the polarized and azimuthal dependencies of optical second harmonics generation (SHG) on polished surfaces of ZnSe(100) single crystal surface in air, using a fundamental wavelength of 1.06μm. By considering both, the bulkand surfaceoptical nonlinearities within the electric dipole approximation, we analysed the data for all four combination of pand s-polarized incidence and output....
