Abstract: This system for cultivating marine species employs a marine-based array of floating closed-containment tanks composed of panels made of waterproof fiberglass laminate materials and internal buoyant foam-based materials. The panels, connected by flanged struts, form the walls and bottom of the tanks, which are substantially cylindrical in overall shape. The tops of the tanks are open to the atmosphere but are protected from predators via a thick mesh top net. The system also employs a filtration system which utilizes centrifugal water flow and hydraulics to remove sludge and solid matter which is then filtered and transformed into a component for use in garden fertilizers. It also uses an electronic computerized system for monitoring and controlling the marine species rearing environment.

Abstract: Embodiments of a flight-control system and methods of reducing the probability of a roll-control reversal in a canard-controlled flight vehicle are generally described herein. In some embodiments, the flight-control system may monitor angular velocities of the flight vehicle to detect the onset of instability and adaptively control an acceleration limit of the flight vehicle based on the detected instability to reduce the probability of a roll-control reversal. The onset of instability may be detected by persistently high angular velocities. The acceleration limit may be further adaptively controlled based on an approach of a vehicle trim limit.
