Proceedings of the Royal Society of London. Series B. Biological Sciences, 1960
The following is an introduction to the differences between water and air as media for propagating sound. What follows and more information on underwater sound can be found in Horton (1957). The main difference between air and water as media for propagating sound lies in their characteristic impedance. This quantity Z

Metastable Underwater Superhydrophobicity
Physical Review Letters, 2010Superhydrophobicity is generally considered to be a thermodynamically stable wetting state. The stability of the plastron (the thin air film separating the substrate from the water in the superhydrophobic state) was studied in underwater experiments. The plastron exhibited a rapid decay after a well defined onset time, which was found to be dependent ...

Underwater Image Enhancement Using a Multiscale Dense Generative Adversarial Network
IEEE Journal of Oceanic Engineering, 2020Underwater image enhancement has received much attention in underwater vision research. However, raw underwater images easily suffer from color distortion, underexposure, and fuzz caused by the underwater scene.

Arthropod Structure & Development, 2004
Lobsters are generalist decapods that evolved in a broad variety of niches in the Northwestern Atlantic. Due to their inherent buoyancy they have acquired adaptations to reduced traction and surge. We have developed a biomimetic robot based on the lobster that features artificial muscle actuators and sensors employing labeled-line codes.

An autonomous underwater vehicle for observation of underwater structure
International Congress Series, 2006Abstract Various kinds of robots have been developed actively with progress of computer, and the operations with robots in the extreme environment such as rescue, space and ocean are getting practical solutions. The underwater robots are expected as one of solutions for underwater activities, i.e., maintenance of underwater structures, observations ...
