Objectives For an electrical propulsion system, the transient torque induced by short-circuit faults is so large that it will exert a greater impact on the Caps safety of shipboard electric propulsion system.In order to evaluate the problem, a simulation method for analyzing the torsional vibration of a propulsion system under a short-circuit-induc
Background.To date, numerous studies of the impact of snail Potamopyrgus antipodarum (Gray, 1843) on invaded ecosystems have been conducted.However, the majority of such studies intended to assess changes induced in macroinvertebrate assemblages, while the possible effects of P.antipodarum on higher trophic levels have not hitherto been studied.Of
This paper presents improved quad-mode resonators based on the open/short-end load of the center stub, which introduces the self-coupled structure.Compared with the traditional stub-loaded stepped impedance resonator (SLSIR), the proposed quad-mode resonators can significantly reduce the circuit size and further increase the design freedom.First of
