Non-integrability of some few body problems in two degrees of freedom
(2008-11-16)
Article
Accés obertThe basic theory of Differential Galois and in particular Morales--Ramis theory is reviewed with focus in analyzing the non--integrability of various problems of few bodies in Celestial Mechanics. The main theoretical ... -
Non-linear dynamics and alternating ‘flip’ solutions in ferrofluidic Taylor-Couette flow
(2018-04-15)
Article
Accés obertThis study treats with the influence of a symmetry-breaking transversal magnetic field on the nonlinear dynamics of ferrofluidic Taylor-Couette flow – flow confined between two concentric independently rotating cylinders. ... -
Nonlinear complexification of periodic orbits in the generalized Landau scenario
(2022-02)
Article
Accés obertWe have found a way for penetrating the space of the dynamical systems towards systems of arbitrary dimension exhibiting the nonlinear mixing of a large number of oscillation modes through which extraordinarily complex ... -

Numerical computation of normal forms around some periodic orbits of the restricted three body problem
(1997)
Article
Accés obertIn this paper we introduce a general methodology for computing (numerically) the normal form around a periodic orbit of an autonomous analytic Hamiltonian system. The process follows two steps. First, we expand the ... -
Numerical continuation methods for large-scale dissipative dynamical systems
(2016-11-22)
Article
Accés obertA tutorial on continuation and bifurcation methods for the analysis of truncated dissipative partial differential equations is presented. It focuses on the computation of equilibria, periodic orbits, their loci of ... -
Numerical study of A+A -> 0 and A+B ->0 reactions with inertia
(American Institute of Physics, 2007-11-30)
Article
Accés obertUsing numerical methods we study the annihilation reactions A + A → 0 and A + B → 0 in one and two dimensions in the presence of inertial contributions to the motion of the particles. The particles move freely following ... -
Numerically solving Hilbert's 16th problem
(Universitat Politècnica de Catalunya, 2021-01)
Treball Final de Grau
Accés obertThe second part of Hilbert's 16th problem remains unresolved more than a century after he first formulated it. This Degree Final Project (TFG) is an attempt to bring the power of modern computers into the equation. In the ... -
Obtaining consensus of singular multi-agent linear dynamic systems
(2016)
Article
Accés obertThere is much literature about the study of the consensus problem in the case where the dynamics of the agents are linear systems, but the problem is still open for the case where the dynamic of the agents are singular ... -
Obtaining of a PET/SiC hybrid multifilament: non-isothermal crystallization studies
(2020-11-04)
Article
Accés obertThermal processing properties are a key factor in the industrial processing industry. The obtaining of a PET-based hybrid composite multifilament with textile properties (yarns) is presented. The system is composed by ... -
On dynamical systems for sensorimotor contingencies. A first approach from control engineering
(IOS Press, 2017)
Text en actes de congrés
Accés obertAccording to the sensorimotor approach, cognition is constituted by regularities in the perceptual experiences of an active and situated agent. This perspective rejects traditional inner representational models, stressing ... -
On the persistence of lower dimensional invariant tori under quasiperiodic perturbations
(1996)
Article
Accés obertIn this work we consider time dependent quasiperiodic perturbations of autonomous Hamiltonian systems. We focus on the effect that this kind of perturbations has on lower dimensional invariant tori. Our results show that, ... -
On the vertical families of two-dimensional tori near the triangular points of the bicircular problem
(1999)
Article
Accés obertThis paper focuses on some aspects of the motion of a small particle moving near the Lagrangian points of the Earth-Moon system. The model for the motion of the particle is the so-called Bicircular problem (BCP), that ... -
Oscillatory motions and parabolic manifolds at infinity in the planar circular restricted three body problem
(Elsevier, 2022-05-25)
Article
Accés obertConsider the Restricted Planar Circular 3 Body Problem. If the trajectory of the body of zero mass is defined for all time, it can have the following four types of asymptotic motion when time tends to infinity forward or ... -
Òrbites d'ejecció-col·lisió en el problema restringit dels tres cossos
(Universitat Politècnica de Catalunya, 2015-07)
Treball Final de Grau
Accés obertEn aquest treball farem un estudi del problema restringit dels tres cossos i de les òrbites d'ejecció-col·lisió. Com és conegut per a valors suficientment petits del paràmetre de mases i regions de Hill prou restrictives ... -
