Abstract: Order tracking (OT) is an effective fault diagnosis method for rotating machinery under variable speed conditions. Accurate instantaneous frequency (IF) is the premise of this method. In ...

Abstract: In order to suppress the swing of slung load during the flight of the quadrotor unmanned aerial vehicle (UAV), a new double closed-loop nonlinear control method Newton–Euler is proposed ...

CÆLUM is a hydrodynamic solver for compressible flows, which solves the Euler equations of gas dynamics by means of very high order essentially non-oscillatory finite volume schemes in cartesian ...

Washington — The White House on Monday said a U.S. attack on an alleged drug boat in September included more than one strike on the vessel, seemingly confirming a Washington Post report that the U.S.
