A Robust Approach for Monocular Visual Odometry in Underwater Environments
(Sociedad Argentina de Informática e Investigación Operativa, 2019)
This work presents a visual odometric system for camera tracking in underwater scenarios of the seafloor which are strongly perturbed with sunlight caustics and cloudy water. Particularly, we focuse on the performance and ...

Where are the turtles when they are not? Underwater refuges used by Hydromedusa tectifera COPE, 1869 in a suburban stream
(Kluwer Academic Publishers, 2020-05-14)
Habitat requirements of Hydromedusa tectifera from an urban impacted stream from the Buenos Aires province, the Rodriguez stream, are here studied. We describe the type of underwater refuges, how they are used in different ...
A 2 1/2 D visual controller for autonomous underwater vehicle
(Escola Politécnicaem Engenharia ElétricaUFBAbrasil, 2017-06-28)
Underwater navigation is affected by the lack of GPS due to the attenuation of the
electromagnetic signals. Thereby, underwater robots rely on dead reckoning as their main
navigation systems. However, localization via ...
Synthesis of a finite-time convergence controller for trajectory tracking of unmanned underwater vehicles
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2021-06)
Unmanned underwater vehicles have gained importance since they can perform tasks in underwater environments such as exploration and construction. Proper control of the vehicle trajectory is fundamental for successfully ...
Arqueologia de ambientes aquáticos: algumas reflexões sobre os sítios depositários

Drought can cause phytoplankton growth intensification in Barra Bonita reservoir
(Springer, 2016-09-01)
In this research, we investigated the possible consequences of the 2012-2014 drought in Southeastern Brazil on growing phytoplankton in a eutrophic reservoir. Weather has direct influence to phytoplankton communities and, ...
Design and construction of the hull of an autonomous underwater vehicle with biomimetic profile and development of instrumentation and control system
Seabed research has motivated the development of Underwater Vehicles (UVs). Study of marine life can be performed using Autonomous Underwater Vehicles (AUVs) but most of the development has been restricted to conventional ...
