A novel acoustic metamaterial structure, made up of both click here resonator and multiple channels, is proposed to insulate low-frequency broadband noises.Three bandgaps with a total width of 658 Hz can be obtained below 900 Hz when the structure appears as a single negative characteristic within specific frequency ranges.These bandgaps are caused

The design of the satellite attitude control system (ACS) becomes more complex when the satellite structure has different type of components like, flexible solar panels, antennas, mechanical manipulators, and tanks with fuel.A crucial interaction can occur between the fuel slosh motion and the satellite rigid motion during translational and/or rota
In many areas of the economy, we deal with random processes, e.g., transport, agriculture, trade, construction, etc.Effective management of such processes often leads to optimization models with random parameters.Solving these problems is already very difficult in deterministic cases, because they usually belong to the NP-hard class.In addition the
