摘要： A gas turbine engine exhaust nozzle arrangement for the flow of exhaust gases therethrough between an upstream end and a downstream end thereof comprising a nozzle and a plurality of tabs which extend in a generally axial direction from a downstream portion of the nozzle wherein the nozzle further comprises an actuation mechanism capable of moving the tabs between a first deployed position, where the tabs interact with a gas stream to reduce exhaust noise thereof, and a second non-deployed position, where the tabs are substantially aerodynamically unobtrusive.

摘要： Scheduling a set of anytime tasks includes assigning a percentage of at least one resource to each of the set of anytime tasks and allowing each of the set of anytime tasks to use the at least one resource in accordance with the respective assigned fraction. The percentage of the at least one resource assigned to each of the set of anytime tasks is subsequently adapted.
