Abstract Recovery of rare earth elements (REEs) from end‐of‐life (EOL) products represents a strategic opportunity to strengthen the domestic supply chain for rare earth elements. This work presents a superstructure‐based optimization framework for finding the most economical processing pathway for different EOL rare earth permanent magnets (REPMs ...

Control Loss Recovery Autopilot Design for Fixed-Wing Aircraft
In this paper a loop-shaping design approach is investigated for distressed fixed-wing aircraft experiencing control loss due to surface or power failure. An accurate nonlinear model of the aircraft dynamics is utilized to obtain a target aircraft behavior in the emergency situation, for which a loop-shaping controller is designed to balance ...
