  • Periodic points of a Landen transformation 

    Gasull, Armengol; Llorens, Mireia; Mañosa Fernández, Víctor (2018-11)
    Article
    Accés restringit per política de l'editorial
    We prove the existence of 3-periodic orbits in a dynamical system associated to a Landen transformation previously studied by Boros, Chamberland and Moll, disproving a conjecture on the dynamics of this planar map introduced ...
  • Real-time seismic data from the bottom sea 

    Roset Juan, Francesc Xavier; Trullols Farreny, Enric; Artero Delgado, Carola; Prat Farran, Joana d'Arc; Río Fernandez, Joaquín del; Massana Hugas, Immaculada; Carbonell Ventura, Montserrat; Toma, Daniel (Multidisciplinary Digital Publishing Institute (MDPI), 2018-04-08)
    Article
    Accés obert
    An anchored marine seismometer, acquiring real-time seismic data, has been built and tested. The system consists of an underwater seismometer, a surface buoy, and a mooring line that connects them. Inductive communication ...
  • Multisymplectic unified formalism for Einstein-Hilbert gravity 

    Gaset Rifà, Jordi; Román Roy, Narciso (2018-03-01)
    Article
    Accés obert
    We present a covariant multisymplectic formulation for the Einstein-Hilbert model of General Relativity. As it is described by a second-order singular Lagrangian, this is a gauge field theory with constraints. The use of ...
  • Decomposing almost complete graphs by random trees 

    Lladó Sánchez, Ana M. (2018-02)
    Article
    Accés restringit per política de l'editorial
    An old conjecture of Ringel states that every tree with m edges decomposes the complete graph K2m+1. The best known lower bound for the order of a complete graph which admits a decomposition by every given tree with m edges ...
  • Consensus, dissension and precision in group decision making by means of an algebraic extension of hesitant fuzzy linguistic term sets 

    Montserrat Adell, Jordi; Agell, Nuria; Sánchez Soler, Monica; Ruiz Vegas, Francisco Javier (Elsevier, 2018-07)
    Article
    Accés restringit per política de l'editorial
    Present measures of the degree of agreement in group decision-making using hesitant fuzzy linguistic term sets allow consensus or agreement measurement when decision makers’ assessments involve hesitance. Yet they do not ...
  • Estimation of the dispersion error in the numerical wave number of standard and stabilized finite element approximations of the Helmholtz equation 

    Steffens, Lindaura Maria; Parés Mariné, Núria; Díez, Pedro (John Wiley & sons, 2011-06-10)
    Article
    Accés obert
    An estimator for the error in the wave number is presented in the context of finite element approximations of the Helmholtz equation. The proposed estimate is an extension of the ideas introduced in Steffens and D'iez ...
  • Physiology-based model of cell viscoelasticity 

    Muñoz Romero, José; Albo Guijarro, Santiago (2013)
    Article
    Accés obert
    The measured viscoelastic properties of biological tissues is the result of the passive and active response of the cells. We propose an evolution law of the remodeling process in the cytoskeleton which is able to mimic the ...
  • GNSS transpolar earth reflectometry exploriNg system (G-TERN): mission concept 

    Cardellach Galí, Estel; Wickert, Jens; Baggen, Rens; Camps Carmona, Adriano José; Hernández Pajares, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2018-03-09)
    Article
    Accés obert
    The global navigation satellite system (GNSS) Transpolar Earth Reflectometry exploriNg system (G-TERN) was proposed in response to ESA's Earth Explorer 9 revised call by a team of 33 multi-disciplinary scientists. The ...
  • Multiway principal component analysis contributions for structural damage localization 

    Ruiz Ordóñez, Magda; Mujica Delgado, Luis Eduardo; Sierra Pérez, Julian; Pozo Montero, Francesc; Rodellar Benedé, José (2017-11-14)
    Article
    Accés obert
    In this article, a novel methodology for damage localization is introduced. The approach is based on a multiactuator system. This means that the system itself has the ability of both exciting the specimen and measuring its ...
  • Dominating 2-broadcast in graphs: complexity, bounds and extremal graphs 

    Cáceres, José; Hernando Martín, María del Carmen; Mora Giné, Mercè; Pelayo Melero, Ignacio Manuel; Puertas González, María Luz (2018-04-20)
    Article
    Accés obert
    Limited dominating broadcasts were proposed as a variant of dominating broadcasts, where the broadcast function is upper bounded. As a natural extension of domination, we consider dominating 2-broadcasts along with the ...
  • Relación de la nota de selectividad y la nota media del primer y segundo curso de los Grados de Energía y Mecánica de la EUETIB 

    López López, José; Buenestado Caballero, Pablo; Grau Barceló, Joan; Martínez Sánchez, Joan; Torres Cámara, Ricardo; Alcaraz Sendra, Olga (2018)
    Comunicació de congrés
    Accés obert
    This work explains te relationships between the final mark of the first and second courses of the Mechanical Engineering degree and Energy Engineering degree with the acces note of the EUETIB. El presente trabajo presenta ...
