British Journal of Orthodontics, 1990
A report is presented of a scuba diver who was unable to dive using a normal commercial mouthpiece due to wearing a fixed orthodontic appliance. The situation was resolved with the provision of a customized mouthpiece of simple design and manufacture.

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1960
Abstract 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.

Proceedings of the Thirteenth ACM International Conference on Underwater Networks & Systems, 2018
The underwater network is a candidate instance of the constrained environment that communicates the facility of the smart underwater objects. The Internet of Underwater Things (IoUT) establishes the network of cognitive underwater devices. The paper primarily focuses on underwater applications based on the management system and we provide a ...

The Internet of Underwater Things
Proceedings of the Twentieth ACM International Symposium on Mobile Ad Hoc Networking and Computing, 2019The Internet of Underwater Things (IoUT) is a novel paradigm for the Blue Economy sector bringing the ability to sense, actuate, exchange information, through low cost technologies, typical of the terrestrial IoT and personal devices, to marine and ocean environments.

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 Suction Gripper for Object Manipulation with an Underwater Robot
2021 IEEE International Conference on Mechatronics (ICM), 2021The diversity of end-effectors for manipulation enables a robot to grasp objects with various shapes. As underwater manipulation becomes more common, various types of end-effectors for underwater robots are required. In this paper, we develop an underwater suction gripper (USG) for object manipulation.

Deskewing of Underwater Images
IEEE Transactions on Image Processing, 2015We address the problem of restoring a static planar scene degraded by skewing effect when imaged through adynamic water surface. In particular, we investigate geometric distortions due to unidirectional cyclic waves and circular ripples,phenomena that are most prevalent in fluid flow.

Abstract Snorkeling and SCUBA diving have become very popular but require a good understanding of the physics and physiology of the environment as well as the equipment used. Breathing nitrogen at excessive depths can lead to serious dysphoria, high pressure oxygen can cause convulsions, while CO2 retention is a potential problem when ...
