An ensemble learning solution for predicitive manintenance of wind turbines main bearing
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-02)
Article
Open AccessA novel and innovative solution addressing wind turbines’ main bearing failure predictions using SCADA data is presented. This methodology enables to cut setup times and has more flexible requirements when compared to the ... -
Rigidity of cotangent lifts and integrable systems
(2020-05)
External research report
Open AccessIn this article we generalize a theorem by Palais on the rigidity ofcompact group actions to cotangent lifts. We use this result to prove rigidity forintegrable systems on symplectic manifolds including sytems with ... -
Regularisation in ejection-collision orbits of the RTBP
(2018)
Conference report
Open AccessNumerical explorations confirm well-known analytical results on the ex-istence of ejection-collision orbits in the restricted three-body problem for veryrestrictive values of the Jacobi constantC. For different values ... -
b-Structures on Lie groups and Poisson reduction
(2020-09)
External research report
Open AccessWe introduce the notion of b-Lie group as a pair(G, H) where Gis a Lie group and H is a codimension-one Lie subgroup, and study the associated canonical b-symplectic structure on the b-cotangent bundle bT*G together with ... -
Integrable systems on singular symplectic manifolds: from local to global
(2020-09)
External research report
Open AccessIn this article we consider integrable systems on manifolds endowed with singular sym-plectic structures of order one. By singular symplectic structures of order one we mean structureswhich are symplectic away from an ... -
A rainbow Dirac's theorem
(2020-01-01)
Article
Open AccessA famous theorem of Dirac states that any graph on n vertices with minimum degree at least n/2 has a Hamilton cycle. Such graphs are called Dirac graphs. Strengthening this result, we show the existence of rainbow Hamilton ... -
New contributions to the Hamiltonian and Lagrangian contact formalisms for dissipative mechanical systems and their symmetries
(2020-06-01)
Article
Restricted access - publisher's policyWe provide new insights into the contact Hamiltonian and Lagrangian formulations of dissipative mechanical systems. In particular, we state a new form of the contact dynamical equations, and we review two recently presented ... -
A canonical realization of the Weyl BMS symmetry

Group inverse matrix of the normalized Laplacian on subdivision networks
(2020)
Article
Open AccessIn this paper we consider a subdivision of a given network and we show how the group inverse matrix of the normalized laplacian of the subdivision network is related to the group inverse matrix of the normalized laplacian ... -
Embeddability and rate identifiability of Kimura 2-parameter matrices
(2020-03-01)
Article
Open AccessDeciding whether a substitution matrix is embeddable (i.e. the corresponding Markov process has a continuous-time realization) is an open problem even for 4×4 matrices. We study the embedding problem and rate identifiability ... -
Damage diagnosis for offshore wind turbine foundations based on the fractal dimension
(2020-10-05)
Article
Open AccessCost-competitiveness of offshore wind depends heavily in its capacity to switch preventive maintenance to condition-based maintenance. That is, to monitor the actual condition of the wind turbine (WT) to decide when and ... -
Rigidity of cotangent lifts and integrable systems
(2020-11)
Article
Open AccessIn this article we generalize a theorem by Palais on the rigidity of compact group actions to cotangent lifts. We use this result to prove rigidity for integrable systems on symplectic manifolds including systems with ...
