When it comes to seaborne propulsion, one simple layout has largely dominated over all others. You pair some kind of engine with some kind of basic propeller at the back of the ship, and then you ...

Abstract: This paper proposes a novel lightweight neural network-PID composite control method to address the challenges of stability in millimeter-wave (mmWave) and terahertz (THz) wireless ...

Abstract: The controllable pitch propeller is a core component of the ship propulsion system, and its performance directly affects the energy efficiency, maneuverability, and safety of the ship. The ...
