Big-bang bifurcations in a first order system with a relay
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialIn this work we describe the bifurcation scenario found in a general first order system when a relay based proportional control is considered. We show the existence of a big bang bifurcation causing the existence of an ... -
Breakdown of homoclinic orbits to L3 in the RPC3BP (I). Complex singularities and the inner equation
(2022-10-29)
Article
Accés obertThe Restricted 3-Body Problem models the motion of a body of negligible mass under the gravitational influence of two massive bodies, called the primaries. If the primaries perform circular motions and the massless body ... -
Cálculo de probabilidades en el análisis de perfiles genéticos compatibles
(Institut d'estadística de Catalunya, 2000)
Article
Accés obert -
Central configurations of the planar coorbital satellite problem
(2003)
Article
Accés obertWe study the planar central configurations of the 1 + n body problem where one mass is large and the other n masses are infinitesimal and equal. We find analytically all these central configurations when 2 ≤ n ≤ 4. Numerically, ... -
Collective behavior of chaotic oscillators with environmental coupling

Collective excitability in a mesoscopic neuronal model of epileptic activity
(2018-01-12)
Article
Accés obertAt the mesoscopic scale, the brain can be understood as a collection of interacting neuronal oscillators, but the extent to which its sustained activity is due to coupling among brain areas is still unclear. Herewe address ... -
Collective versus hub activation of epidemic phases on networks
(AMER PHYSICAL SOC, 2016-03-14)
Article
Accés restringit per política de l'editorialWe consider a general criterion to discern the nature of the threshold in epidemic models on scale-free (SF) networks. Comparing the epidemic lifespan of the nodes with largest degrees with the infection time between them, ... -
Computational models of mammalian brains in transient dynamics
(Universitat Politècnica de Catalunya, 2018-05-11)
Projecte Final de Màster Oficial
Accés obertTo date, the brain remains the most intriguing and unexplored organ in humans. Understanding its mechanical behavior is crucial for the study of brain diseases involving brain deformation in traumatic brain injury. Despite ... -
Conductance heterogeneities induced by multistability in the dynamics of coupled cardiac gap junctions
(2021-07-01)
Article
Accés obertIn this paper, we study the propagation of the cardiac action potential in a one-dimensional fiber, where cells are electrically coupled through gap junctions (GJs). We consider gap junctional gate dynamics that depend on ... -
Conservació de l'estructura PHS en reduccions d'ordre per truncament equilibrat
(2008-01-16)
Report de recerca

Contrôle du comportement routier d'un véhicule innovant
(Universitat Politècnica de Catalunya / École Centrale Lyon, 2011)
Projecte/Treball Final de Carrera
Accés restringit per decisió de l'autorEn accord avec la démarche de conception d'un produit dite méthode du « cycle en V », tout produit à concevoir doit être dans un premier temps analysé en fonction de sa fonctionnalité future (analyse fonctionnelle), puis ... -
Converse flexoelectricity yields large piezoresponse force microscopy signals in non-piezoelectric materials
(2019-03-20)
Article
Accés obertConverse flexoelectricity is a mechanical stress induced by an electric polarization gradient. It can appear in any material, irrespective of symmetry, whenever there is an inhomogeneous electric field distribution. This ... -
Correlation lags give early warning signals of approaching bifurcations
(2022-02-01)
Article
Accés obertIdentifying approaching bifurcations and regime transitions from observations is an important challenge in time series analysis with practical applications in many fields of science. Well-known indicators are the increase ... -
D-NeRF: neural radiance fields for dynamic scenes
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Text en actes de congrés
Accés obertNeural rendering techniques combining machine learning with geometric reasoning have arisen as one of the most promising approaches for synthesizing novel views of a scene from a sparse set of images. Among these, stands ... -
DAE Methods in Constrained Robotic System Simulation:
(Centro de Investigación en Computación, 1998-03)
Article
Accés obertIn this paper a DAE formulation is used to model the behaviour of constrained robotic systems. This formulation allows to specify in an easy and clear way the constrained behaviour of a robotic system. In order to better ... -
Les Danses dels N cossos
(2013-10-02)
Audiovisual
Accés obertEl problema gravitatori de N cossos només admet solucions explícites en el cas N=2 i en alguns cassos molt simètrics si N>2. Una d'aquestes solucions per a N=3 fou descoberta per Lagrange (Torino 1736 - Paris 1813) l'any ... -
Design of a dynamic diffuser for the aerodynamic improvement of a vehicle
(Universitat Politècnica de Catalunya, 2022-01-27)
Treball Final de Grau
Accés obertÉs ben conegut l’impacte que té sobre el rendiment aerodinàmic, el fet d’incorporar un sòl pla i un difusor a un vehicle. Normalment els difusors se solen centrar en l’eix de simetria longitudinal. No obstant, la transferència ... -
