Prediction of Parametric Roll of Ships in Regular and Irregular Sea
… available to analyze the system retaining the non-linear character of the system. The Hill’ equation is used to develop highly accurate stability boundaries in the Ince-Strutt Diagram. The effect of non-linear damping has also been incorporated into the chart for the first time providing a …

Dynamic range implications for the effectiveness of semi-active tuned mass dampers
… tuned mass damper (TMD), which acts as a passive damping device in the region of the tuned frequency. However, TMDs exhibit a limited bandwidth and often require a significant mass. Active systems, such as the active mass driver, have been utilized to improve the effectiveness of the TMD concept, …

Hydrodynamic modelling of the oscillating wave surge converter
… coefficients are calculated with the linear wave – structure interaction analysis software WAMIT and the remaining coefficients are determined from data acquired from tests in a wave tank with a physical scale model of the device.<br/><br/>The second numerical model is based on …

Modeling of equilibrium point trajectory control in human arm movements
… the use of complex virtual trajectories, non-linear damping, stiffness and time varying stiffness to the EPH model. While these features allow the EPH to adequately produce human joint velocities, they conflict with the EPH's premise of simple pre-planned monotonic control of movement …
