Power input to non-deterministic subsystems via piezoelectric patch actuators: effect of the patch size and location

Many engineering systems such as aircraft and automotive are considered built-up structures, fabricated from components that are classified as deterministic subsystems (DS)and non-deterministic subsystems (Non-DS). The response of Non-DS is sensitive to uncertainties therefore presents problems in v...
