Abstract: Unlike the popularly used approaches (in which the time-varying nature of the system’s dynamics is neglected), a Lyapunov-based nonlinear time-varying framework is provided to handle the longitudinal control of tilt rotor ...

Abstract: The effect of graphite (Gr) content on tribological performance of copper-matrix composites against H13 steel was investigated using a pin-on-disk test in the range of 3.14–47.1 m/s. The composites with different weight ...

Abstract: Anthropogenically forced-warming and La Niña forced-precipitation deficits caused at least a sixfold risk increase for compound extreme low precipitation and high temperature in California–Nevada from October 2020 to ...
