  • Monomial codes seen as invariant subspaces 

    García Planas, María Isabel; Magret Planas, Maria dels Dolors; Um, Laurence Emilie (2017)
    Article
    Accés obert
    It is well known that cyclic codes are very useful because of their applications, since they are not computationally expensive and encoding can be easily implemented. The relationship between cyclic codes and invariant ...
  • Ejection-collision orbits in the Restricted three-body problem 

    Ollé Torner, Mercè; Rodríguez del Río, Óscar; Soler Villanueva, Jaume (2018-02)
    Article
    Accés restringit per política de l'editorial
    In this paper we analyse the ejection-collision (EC) orbits of the planar restricted three body problem. Being µ¿¿¿(0, 0.5] the mass parameter, and taking the big (small) primary with mass (µ), an EC orbit will be an orbit ...
  • Enumeration of labeled 4-regular planar graphs 

    Noy Serrano, Marcos; Requile, Clement; Rué Perna, Juan José (2017-08-01)
    Article
    Accés obert
    In this extended abstract, we present the first combinatorial scheme for counting labeled 4-regular planar graphs through a complete recursive decomposition. More precisely, we show that the exponential generating function ...
  • Iterative Learning Control for homing guidance design of missiles 

    Acho Zuppa, Leonardo (Elsevier, 2017-02-16)
    Article
    Accés obert
    This paper presents an Iterative Learning Control design applied to homing guidance of missiles against maneuvering targets. According to numerical experiments, although an increase of the control energies is appreciated ...
  • Estimation of synaptic conductance in the spiking regime for the McKean neuron model 

    Guillamon Grabolosa, Antoni; Prohens Sastre, Rafel; Teruel Aguilar, Antonio E.; Vich Llompart, Catalina (2017-01-01)
    Article
    Accés obert
    In this work, we aim at giving a first proof of concept to address the estimation of synaptic conductances when a neuron is spiking, a complex inverse nonlinear problem which is an open challenge in neuroscience. Our ...
  • A family of stacked central configurations in the planar five-body problem 

    Lino Cornelio, J.; Alvarez Ramírez, Martha; Cors Iglesias, Josep Maria (2017-11)
    Article
    Accés restringit per política de l'editorial
    We study planar central configurations of the five-body problem where three bodies, (Formula presented.) and (Formula presented.), are collinear and ordered from left to right, while the other two, (Formula presented.) and ...
  • Phragmén-Lindelöf alternative for the Laplace equation with dynamic boundary conditions 

    Leseduarte Milán, María Carme; Quintanilla de Latorre, Ramón (2017-11-01)
    Article
    Accés obert
    This paper investigates the spatial behavior of the solutions of the Laplace equation on a semi-infinite cylinder when dynamical nonlinear boundary conditions are imposed on its lateral side. We prove a Phragmén-Lindelöf ...
  • The matter-ekpyrotic bounce scenario in Loop Quantum Cosmology 

    Haro Cases, Jaume; Amorós Torrent, Jaume; Aresté Saló, Llibert (2017-09-01)
    Article
    Accés restringit per política de l'editorial
    We will perform a detailed study of the matter-ekpyrotic bouncing scenario in Loop Quantum Cosmology using the methods of the dynamical systems theory. We will show that when the background is driven by a single scalar ...
  • Viscous cosmology for early- and late-time universe 

    Brevik, Iver; Grøn, Øyvind; Haro Cases, Jaume; Odintsov, Sergei D.; Saridakis, Emmanuel N. (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all an abstraction (exluding special cases such as superconductivity). ...
