Improving ocean-glider's payload with a new generation of spectrophotometric PH sensor
Ocean gliders have clearly become nowadays useful autonomous
platforms addressed to measure a wide range of seawater parameters in a more
sustainable and efficient way. This new ocean monitoring approach has implied
the need to develop smaller, faster and more efficient sensors without reducing key
features like accuracy, resolution, time-response, among others, in order to fit the
glider operational capabilities. This work is aiming to present the latest development
stages of a new spectrophotometric pH sensor, its integration process into a Wave
Glider SV3 platform and the preliminary results derived from an offshore mission
performed in subtropical waters between the Canary Islands and Cape Verde
archipelagos.Peer Reviewe
Constant of Motion for several one-dimensional systems and outlining the problem associated with getting their Hamiltonians
The constants of motion of the following systems are deduced: a relativistic
particle with linear dissipation, a no-relativistic particle with a time
explicitly depending force, a no-relativistic particle with a constant force
and time depending mass, and a relativistic particle under a conservative force
with position depending mass. The problem of getting the Hamiltonian for these
systems is determined by getting the velocity as an explicit function of
position and generalized linear momentum, and this problem can be solved a
first approximation for the first above system.Comment: 15 pages, Te
Smart and networking underwater robots in cooperation meshes : the swarms ECSEL : H2020 project
The work presented on this paper is aimed to explain the role that
unmanned underwater vehicles (AUVs/ROVs) plays in the ECSEL-H2020 SWARMS
project. The main goal of the project is to reduce the operational cost and increase
the safety of tasks assigned to divers in these operations. This will be achieved
enabling the AUVs/ROVs to work in a cooperative mesh. The challenge is to design
and develop an integrated platform (a set of Software/Hardware components),
incorporated into the current generation of underwater vehicles in order to
improve autonomy, cooperation, robustness, cost-effectiveness, and reliability of
the offshore operations. The first demonstration of the project will be performed at
PLOCAN (Oceanic Platform of the Canary Islands) where these technologies will be
validated on its first stage.Peer Reviewe
