    Part of book or chapter of book
    Open Access
    This paper proposes a way of approximating the solution of partial differential equations (PDE) using Deep Neural Networks (DNN) based on Keras and TensorFlow, that is capable of running on a conventional laptop, which is ...

    Part of book or chapter of book
    Open Access
    La situación actual derivada de la crisis del COVID-19 está generando desafíos sin precedentes en toda la comunidad educativa, aunque las instituciones de educación superior han demostrado su capacidad para adaptarse muy ...
  • The expected number of perfect matchings in cubic planar graphs 

    Rué Perna, Juan José; Requile, Clement; Noy Serrano, Marcos (Birkhäuser, 2021-09-01)
    Part of book or chapter of book
    Restricted access - publisher's policy
    A well-known conjecture by Lovász and Plummer from the 1970s asserting that a bridgeless cubic graph has exponentially many perfect matchings was solved in the affirmative by Esperet et al. (Adv. Math. 2011). On the other ...

  • When is a complete ideal in a rational surface singularity a multiplier ideal? 

    Alberich Carramiñana, Maria; Álvarez Montaner, Josep; González Alonso, Víctor (Springer-Birkhäuser, 2021)
    Part of book or chapter of book
    Restricted access - publisher's policy
    This is an extended abstract with some of the results that will appear in the forthcoming paper [1] in which we characterize when a given complete ideal in a two-dimensional local ring with a rational singularity can be ...
  • Developable surfaces with prescribed boundary 

    Alberich Carramiñana, Maria; Amorós Torrent, Jaume; Coltraro Ianniello, Franco (Springer-Birkhäuser, 2021)
    Part of book or chapter of book
    Open Access
    It is proved that a generic simple, closed, piecewise regular curve in space can be the boundary of only infinitely many developable surfaces with nonvanishing mean curvature. The relevance of this result in the context ...
  • Assessment of exams at Atenea, an IMS LTI application for scalability problems 

    Alier Forment, Marc; Casany Guerrero, María José; Llorens García, Ariadna; Alcober Segura, Jesús Ángel; Prat Farran, Joana d'Arc (Book Publisher International, 2021-12-22)
    Part of book or chapter of book
    Restricted access - publisher's policy
    The online teaching support platform was changed by the Universitat Politècnica de Catalunya in 2004. Moodle, an open source software, was used in place of the prior proprietary software. The population's confinement at ...
  • Rank conditions on phylogenetic networks 

    Casanellas Rius, Marta; Fernández Sánchez, Jesús (Birkhäuser, 2021)
    Part of book or chapter of book
    Restricted access - publisher's policy
    Less rigid than phylogenetic trees, phylogenetic networks allow the description of a wider range of evolutionary events. In this note, we explain how to extend the rank invariants from phylogenetic trees to phylogenetic ...
  • Reeb embeddings and universality of Euler flows 

    Cardona Aguilar, Robert; Miranda Galcerán, Eva; Peralta Salas, Daniel; Presas, Francisco (Springer, 2021)
    Part of book or chapter of book
    Open Access
    We use a new geometrical approach to the universality of Euler flows. By proving flexibility results on embeddings for Reeb flows in contact topology, we deduce some new universal properties for Euler flows. As a byproduct, ...
  • La enseñanza del concepto de función en los tratados de Benito Bails (1731-1797) 

    Martinez Verdu, Domingo; Massa Esteve, Maria Rosa (Societat Catalana d'Història de la Ciència i de la Tècnica (SCHCT), 2021-09)
    Part of book or chapter of book
    Open Access
    La creación del concepto general de función supuso tanto un gran cambio en los fundamentos del cálculo como un impulso añadido a su «desgeometrización». Se fue reemplazando en el cálculo el uso de lascantidades geométricas ...
