A control system combining input shaping and feedback is applied to a double-pendulum bridge crane subjected to external disturbances. The external disturbances represent naturally occurring forces, such as gusting winds. The proposed control method achieves fast point-to-point response similar to open-loop input-shaping control. It also minimizes transient deflections and disturbance-induced r...

Gridded model assessments require at least one climatic and soil database for carrying out the simulations. There are several parallel climate development projects that provide sufficient, albeit considerably different, observation based input data crop impact studies. The related uncertainty of Biome-BGCMuSo agro-environmental outputs was investigated using three four different gridded databas...
