[Objectives] To study the target assignment in the formation reconfiguration of unmanned ships,a target assignment method is proposed.[Methods] Firstly,a distance-based cost function is generated by the current positions of the unmanned ships and the fixed target points.Secondly,based on the auction theory and according to the rapidity requirement
Abstract Light-emitting electrochemical cells (LECs) are next-generation devices that are flexible, emit light and have several advantages over organic light-emitting diodes, such as a simpler structure and lower cost.However, the operation mechanism of LECs remains unknown from a microscopic viewpoint.Here, we 3282770208962 perform an operando mic
