Digital soil mapping and GlobalSoilMap. Main advances and ways forward
(Elsevier, 2020)
In this concluding paper, we summarize the main advances coming forward from the joint conference of the International Union of Soil Sciences (IUSS) Working Groups (WG) "Digital Soil mapping" (DSM) and "GlobalSoilMap". We ...

Biparametric investigation of the general standard map: multistability and global bifurcations
(2018-07-01)
We investigate multistability and global bifurcations in the general standard map, a biparametric two-dimensional map. Departing from the conservative case of the map, we describe the evolution of periodic solutions and ...

Polar foliations and isoparametric maps
(SPRINGERDORDRECHT, 2012-02)
A singular Riemannian foliation F on a complete Riemannian manifold M is called a polar foliation if, for each regular point p, there is an immersed submanifold Sigma, called section, that passes through p and that meets ...
Performance analysis of global and regional ionosphere maps for generation of virtual reference stationAnálise da performance dos mapas globais e regionais da ionosfera para geração de estação de referência virtual
(2020-01-01)
An important tendency in recent years has been the use of the Real Time Kinematic (RTK) method, due to centimeter accuracy and productivity. However, the RTK is restricted to applications with a baseline below 20 km. To ...
Assessment of global ionospheric maps performance by means of ionosonde data
(2020-10-02)
This work presents a new method for assessing global ionospheric maps (GIM) using ionosonde data. The method is based on the critical frequency at the F2 layer directly measured by ionosondes to validate VTEC (vertical ...
