  • El impacto de las políticas de evaluación del profesorado en la posición en los ránquines universitarios: el caso de la Universidad Politécnica de Cataluña 

    García-Berro Montilla, Enrique; Roca Martín, Santiago; Navallas Ramos, Francisco Javier; Soriano Ibáñez, Miguel; Ras Sabido, Antoni (2016-01)
    Article
    Open Access
    La universidad española ha afrontado con éxito el tránsito entre una universidad clásica, eminentemente docente, y una universidad moderna, en la que la investigación juega un papel esencial. Gran parte de este éxito reside ...

  • Polygons as sections of higher-dimensional polytopes 

    Padrol Sureda, Arnau; Pfeifle, Julián (2015-02-09)
    Article
    Open Access
    We show that every heptagon is a section of a 3-polytope with 6 vertices. This implies that every n-gon with n >= 7 can be obtained as a section of a (2 + [n/7])-dimensional polytope with at most [6n/7] vertices; and ...
  • Automorphisms and reduction of Heegner points on Shimura curves at Cerednik-Drinfeld primes 

    Molina Blanco, Santiago; Rotger Cerdà, Víctor (2014)
    Article
    Open Access
    The aim of this short note is to show how the interplay of the action of the automorphism group of a Shimura curve on the special fiber of its Cerednik-Drinfeld’s integral model at a prime of bad reduction and its sets ...
  • The kernel of Ribet’s isogeny for genus three Shimura curves 

    Molina Blanco, Santiago; González Rovira, Josep (2015)
    Article
    Open Access
    There are exactly nine reduced discriminants D of indefinite quaternion algebras over Q for which the Shimura curve XD attached to D has genus 3. We present equations for these nine curves. Moreover, for each D we determine ...
  • Minimal representations for majority games 

    Freixas Bosch, Josep; Molinero Albareda, Xavier; Roura Ferret, Salvador (2007-02)
    External research report
    Open Access
    This paper presents some new results about majority games. Isbell (1959) was the first to find a majority game without a minimum normalized representation; he needed 12 voters to construct such a game. Since then, it has ...
  • Cell-centred model for the simulation of curved cellular monolayers 

    Mosafa, Payman; Asadipour, Nina; Millán, Raúl Daniel; Rodríguez Ferran, Antonio; Muñoz Romero, José (2015)
    Article
    Open Access
    This paper presents a cell-centred model for the simulation of planar and curved multicellular soft tissues. We propose a computational model that includes stress relaxation due to cell reorganisation (intercellular ...

  • Instability of stationary solutions of reaction-diffusion-equations on graphs 

    Von Below, Joachim; Lubary Martínez, José Antonio (2015-09-01)
    Article
    Restricted access - publisher's policy
    The nonexistence of stable stationary nonconstant solutions of reaction-diffusion-equations partial derivative(t)u(j) = partial derivative(j)(a(j)(x(j))partial derivative(j)u(j)) + f(j)(u(j)) on the edges of a finite ...
  • Space Weather Prediction System providing forecasts and alerts on solar flares and SEP events 

    García Rigo, Alberto; Nuñez, Marlon; Qahwaji, Rami; Ashamari, Omar W; Jiggens, Piers; Pérez, Gustau; Hernández Pajares, Manuel; Hilgers, Alain (2015)
    Conference lecture
    Open Access
    A web-based prototype system for predicting Solar Flares and Solar Energetic Particle (SEP) events for its use by space launcher operators or any interested user has been implemented. The main goal of this system, called ...
