Abstract: This paper addresses the optimal control problem for a class of nonlinear systems that present significant challenges due to state constraints, unmodeled dynamics, and a nonstrict feedback ...

Abstract: Azimuth thrusters are widely used for controlling marine vehicles, especially, for dynamic positioning and hovering purposes. However, including azimuth thruster makes control allocation a ...

Blinking powers a new eye-tracking system to enable wheelchair-bound people to control their movement. The state of the art self-powered eye tracker harnesses energy from simply blinking - and is as ...

Scientists discovered that a subtle behavior by the female of the species dictates whether the quick-fire procreation process is successful. The American research team say their findings may improve ...
