Efficient implementation of symplectic implicit Runge-Kutta schemes with simplified Newton iterations
(2017-03-30)
We are concerned with the efficient implementation of symplectic
implicit Runge-Kutta (IRK) methods applied to systems of (non-necessarily
Hamiltonian) ordinary differential equations by means of Newton-like iterations. ...
Reducing and monitoring round-off error propagation for symplectic implicit Runge-Kutta schemes
(2017-01-31)
We propose an implementation of symplectic implicit Runge-Kutta schemes for highly accurate numerical integration of non-stiff Hamiltonian systems based on fixed point iteration. Provided that the computations are done in ...
A Multi-Disciplinary Approach to Remote Sensing through Low-Cost UAVs
(MDPI, 2017-06)
The use of Unmanned Aerial Vehicles (UAVs) based on remote sensing has generated low cost monitoring, since the data can be acquired quickly and easily. This paper reports the experience related to agave crop analysis with ...
Detecting the presence-absence of bluefin tuna by automated analysis of medium-range sonars on fishing vessels
(Public Library Science, 2017-02-02)
This study presents a methodology for the automated analysis of commercial medium range sonar signals for detecting presence/absence of bluefin tuna (Tunnus thynnus) in the Bay of Biscay. The approach uses image processing ...
