Testing the accuracy of Coimbra Astronomical Observatory solar filament historical series (1929-1941)
Ana Lourenço, Ricardo Gafeira, Vitor Bonifacio +3
The present work aims to validate the positions of solar filaments published in the Annals of Coimbra University Astronomical Observatory, currently the Geophysical and Astronomica…
Numerical solution for a non-Fickian diffusion in a periodic potential
Adérito Araújo, Amal K. Das, Cidália Neves +1
Numerical solutions of a non-Fickian diffusion equation belonging to a hyperbolic type are presented in one space dimension. The Brownian particle modelled by this diffusion equati…
On the multivariate upcrossings index
Clara Viseu, Luísa Pereira, Ana Paula Martins +1
The notion of multivariate upcrossings index of a stationary sequence is introduced and its main properties are derived, namely th…
Irreducible actions and compressible modules
Inês Borges, Christian Lomp
Any finite set of linear operators on an algebra yields an operator algebra and a module structure on A, whose endomorphism ring is isomorphic to a subring of certain…
