Multiple floods interactions shape riparian plant communities and diversity [PDF]
Disturbances are pivotal ecological events that influence the formation of biological communities. Although disturbances have been studied in isolation, studies recently have highlighted the interaction among multiple disturbances.

Periodic Disturbance Compensation Control of a Rope-Driven Lower Limb Rehabilitation Robot
In order to solve the external periodic disturbance and unknown dynamics influence in the passive rehabilitation process of a rope-driven lower limb rehabilitation robot, a control method with periodic repeated learning was designed.

ROBUST REJECTION OF PERIODIC AND ALMOST PERIODIC DISTURBANCES [PDF]
Abstract We present algorithms to exponentially reject periodic and almost periodic disturbances, the motivating application being a rejection of reel eccentricity induced disturbances in tape-drive systems. The prevalent periodic disturbance rejection algorithms rely on a constant gain approximation of the system at a particular frequency. These are
