TL;DR: The fluid dynamics of flapping foils are reviewed in this paper, where a wide range of researches are conducted for the two-dimensional flapping foil which has a relatively simple geometry, however, for a three-dimensional foil, the aspect ratio and shape take effects and completely distinct fluid dynamics are revealed compared with the 2D one.

TL;DR: In this article, an adaptive bistable power capture mechanism is proposed for point absorber wave energy converters in regular waves, which is realized by two symmetrically oblique main springs together with two auxiliary springs and can adjust the potential function automatically to lower the potential barrier near the unstable equilibrium position.

TL;DR: An 8 degree-of-freedom (DOF) mathematical model of the wave glider based on the active propeller control is developed and the results demonstrate that the propellers control based waveglider has better maneuverability than the conventional rudder control basedwave glider.

TL;DR: This paper proposes the concept of a learning-based deep-sea visual monitoring system, uses the gradient generation adversarial network (GGAN) to recover the heavily destroyed underwater images, and proposes using deep compressed learning for real-time communication.

TL;DR: Wang et al. as discussed by the authors used a hydrodynamic transfer function to calculate the amplitude of wave-maker motion associated with each wave component, then superposition was carried out on all of the wave-makers motion components to get the final wavemaker motion.
