A dynamic Parrondo's paradox for continuous seasonal systems
(2020-10)
Article
Accés obertWe show that planar continuous alternating systems, which can be used to model systems with seasonality, can exhibit a type of Parrondo’s dynamic paradox, in which the stability of an equilibrium, common to all seasons is ... -

(2019-11-27)
Report de recerca
Accés obertWe show that planar continuous alternating systems, which can be used to model systems with seasonality, can exhibit a type of Parrondo's dynamic paradox, in which the stability of an equilibrium, common to all seasons is ... -
A route to chaos in the Boros-Moll map
(2018-04-18)
Report de recerca
Accés obertThe Boros-Moll map appears as a subsystem of a Landen transformation associated to certain rational integrals and its dynamics is related to the convergence of them. In the paper, we study the dynamics of a one-parameter ... -

Accés obertThe Boros–Moll map appears as a subsystem of a Landen transformation associated to certain rational integrals and its dynamics is related to their convergence. In the paper, we study the dynamics of a one-parameter family ... -
A Second Order Expansion of the Separatrix Map for Trigonometric Perturbations of a Priori Unstable Systems
(2016-11-01)
Article
Accés obertIn this paper we study a so-called separatrix map introduced by Zaslavskii–Filonenko (Sov Phys JETP 27:851–857, 1968) and studied by Treschev (Physica D 116(1–2):21–43, 1998; J Nonlinear Sci 12(1):27–58, 2002), Piftankin ... -
A study on the generation of chaos due to the presence of smale horseshoes in dynamical systems with a homoclinic orbit
(Universitat Politècnica de Catalunya, 2020-07)
Projecte Final de Màster Oficial
Accés obertOne of the fundamental problems in dynamical systems is the detection and characterisation of chaotic behaviours. In this work we will focus on chaos induced by what is called the Smale horseshoe. Smale horseshoes frequently ... -

(2020-01-01)
Article
Accés obertThe purpose of this paper is to present an example of a (in the Fréchet sense) discrete dynamical system in a infinite-dimensional separable Hilbert space for which the origin is an exponentially asymptotically stable ... -

Analysis of the equations governing the motion of a degrading elastic solid due to diffusion of a fluid
(2014-10)
Article
Accés obertDegradation of solids bearing load due to the infusion of moisture when exposed to the environment can leads to a decrease in their load carrying capacity and can also lead to the failure of the body from performing its ... -
Analysis of the relative dynamics of a charged spacecraft moving under the influence of a magnetic field
(2018-09-01)
Article
Accés obertWe analyse a dynamical scenario where a constantly charged spacecraft (follower) moves in the vicinity of another one (leader) that follows a circular Keplerian orbit around the Earth and generates a rotating magnetic ... -
