Recently, data collection from seabed by means of underwater wireless sensor networks (UWSN) has attracted considerable attention. Autonomous underwater vehicles (AUVs) are increasingly used as UWSNs in underwater missions. Events and environmental parameters in underwater regions have a stochastic nature. The target area must be covered by sensors to observe and report events. A ‘topology cont...

Results are reported on two aspects of underwater vision, apparent distance and hand-eye coordination. The accuracy of distance estimates underwater varies greatly from underestimation at near distances, to overestimation at far distances. Viewing through turbid water rather than clear water greatly increases the tendency toward overestimation. The ability of subjects to perform motor responses...

Abstract This article presented the results of development and calculation plant supply system for an underwater dock station using a three-phase float wave power inverted construction. The completed work allow to solve problem creating stations resident robots, as well speed up their implementation in practice.

The research of Underwater Acoustic Networks (UANs) is attracting attention due to their important underwater applications for military and commercial purposes. Underwater wireless communication networks (UWCNs) consist of sensors and autonomous underwater vehicles (AUVs) that interact, coordinate and share information with each other to carry out sensing and monitoring functions. In last sever...

objectives: the main purpose of this experimental research was to create an animal model of ptsd based on the main features of the disorder: trauma exposure, situational reminders (sr), behavioral anxiety and remedy in response to anxiolytic medications. method: 6 inbred female sprague-dawley rats were obtained and evaluated in the elevated plus-maze test in 3 stages: 1- baseline 2- underwater ...

Development of autonomous underwater vehicles (AUVs) which meets the design constraints and provides the best hydrodynamic performance is really an important challenge in the field of hydrodynamics. In this paper a new profile is used for designing the hull of AUVs. The nose and tail profiles of an AUV using presented profile is designed such that it can properly consider the length constraints...

Children in a tribe of sea-gypsies from South-East Asia have been found to have superior underwater vision compared to European children. In this study, we show that the improved underwater vision of these Moken children is not due to better contrast sensitivity in general. We also show that European children can achieve the same underwater acuity as the Moken children. After 1 month of underwa...
