  • On the passivity of hysteretic systems with double hysteretic loops 

    Pozo Montero, Francesc; Zapateiro De La Hoz, Mauricio Fabian (2015-12-03)
    Article
    Open Access
    The Bouc–Wen hysteresis model is widely employed to mathematically represent the dynamical behavior of several physical devices, materials and systems such as magnetorheological dampers, lanthanide zirconium or aluminum ...
  • Master-slave approach for the modelling of joints with dependent degrees of freedom in flexible mechanisms 

    Muñoz Romero, José; Jelenic, Gordan; Crisfield, M. A. (2003-08-06)
    Article
    Open Access
    The analysis of multibody systems requires an exact description of the kinematics of the joints involved. In the present work the master–slave approach is employed and endowed with the possibility of including several more ...
  • Detection of structural changes through principal component analysis and multivariate statistical inference 

    Pozo Montero, Francesc; Arruga Cantalapiedra, Ignacio; Mujica Delgado, Luis Eduardo; Ruiz Ordóñez, Magda; Podivilova, Elena (2016-01-27)
    Article
    Open Access
    This article introduces a new methodology for the detection of structural changes using a statistical data-driven modeling approach by means of a distributed piezoelectric active sensor network at different actuation phases. ...
  • Recovering the conductances on grids: A theoretical justification 

    Arauz Lombardia, Cristina; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Mitjana Riera, Margarida (2016)
    Article
    Open Access
    In this work, we present an overview of the work developed by the authors in the context of inverse problems on nite networks. This study performs an extension of the pioneer studies by E.B. Curtis and J.A. Morrow, ...
  • Some advances in the theory of voting systems based on experimental algorithms 

    Freixas Bosch, Josep; Molinero Albareda, Xavier (2006-01)
    External research report
    Open Access
    In voting systems, game theory, switching functions, threshold logic, hypergraphs or coherent structures there is an important problem that consists in determining the weightedness of a voting system by means of trades ...
  • On the Partition Dimension and the Twin Number of a Graph 

    Hernando Martín, María del Carmen; Mora Giné, Mercè; Pelayo Melero, Ignacio Manuel (2016-03-05)
    External research report
    Open Access
    A partition of the vertex set of a connected graph G is a locating partition of G if every vertex is uniquely determined by its vector of distances to the elements of . The partition dimension of G is the minimum ...
  • On the one-phase reduction of the Stefan problem with a variable phase change temperature 

    Myers, Timothy; Font, F (2015-02)
    Article
    Restricted access - publisher's policy
    The one-phase reduction of the Stefan problem, where the phase change temperature is a variable, is analysed. It is shown that problems encountered in previous analyses may be traced back to an incorrectly formulated Stefan ...
  • Boundary layer analysis and heat transfer of a nanofluid 

    MacDevette, M.M.; Myers, Timothy; Wetton, B. (2014-08)
    Article
    Open Access
    A theoretical model for nanofluid flow, including Brownian motion and thermophoresis, is developed and analysed. Standard boundary layer theory is used to evaluate the heat transfer coefficient near a flat surface. The ...
  • Enumerating simplicial decompositions of surfaces with boundaries 

    Bernardi, Olivier; Rué Perna, Juan José (2012-04-02)
    Article
    Open Access
    It is well-known that the triangulations of the disc with n + 2 vertices on its boundary are counted by the nth Catalan number C(n) = 1 n+1 (2n n ) . This paper deals with the generalisation of this problem to any compact ...
  • On polynomial representation functions for multivariate linear forms 

    Rué Perna, Juan José (2013-11-01)
    Article
    Open Access
    Given an infinite sequence of positive integers A, we prove that for every nonnegative integer k the number of solutions of the equation n = a1 +· · ·+ak, a1, . . . , ak ¿ A, is not constant for n large enough. This result ...
