  • A shared-parameter joint model for prostate cancer risk and psa longitudinal profiles 

    Serrat Piè, Carles; Rué, Montserrat; Perpiñán Fabuel, Hèctor; Forte, Anabel; Armero, Carmen; Piulachs, Xavier; Páez, Álvaro; Gómez Melis, Guadalupe (Fundación Mapfre, 2015)
    Conference report
    Open Access
    The paper describes the use of frequentist and Bayesian shared-parameter joint models of longitudinal measurements of prostate specific antigen (PSA) and the risk of prostate cancer (PCa). The motivating dataset corresponds ...
  • Region-based approximation algorithms for visibility between imprecise locations 

    Buchin, Kevin; Kostitsyna, Irina; Löffler, Maarten; Silveira, Rodrigo Ignacio (2015)
    Conference report

    In this paper we present new geometric algorithms for approximating the visibility between two imprecise locations amidst a set of obstacles, where the imprecise locations are modeled by continuous probability distributions. ...

    We consider stabbing regions for a set S of n line segments in the plane, that is, regions in the plane that contain exactly one endpoint of each segment of S. Concretely, we provide efficient algorithms for reporting all ...
  • Disturbance decoupling problem for switched linear systems. A geometric approach 

    García Planas, María Isabel (WSEAS Press, 2015)
    Article
    Open Access
    In this paper disturbance decoupling problem for switched linear systems is formulated under a geometrical point of view. Necessary and sufficient conditions for the problem with standardizable condition to be solvable are given
  • Overdetermined partial resolvent kernels for finite networks 

    Arauz Lombardia, Cristina; Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos (2016-03-01)
    Article
    Open Access
    In [2], a study of the existence and uniqueness of solution of partial overdetermined boundary value problems for finite networks was performed. These problems involve Schrodinger operators and the novel feature is that ...

  • Weierstrass per ell mateix: alguns trets del seu pensament matemàtic 

    Massa Esteve, Maria Rosa (2015-03-25)
    External research report
    Open Access
    El coneixement de Karl Weierstrass (1815-1897) a través dels teoremes que s’estudien a les classes de matemàtiques ens aporta una visió parcial del personatge. En aquesta ponència es pretén enriquir aquesta visió apropant-nos ...
  • Determination of criteria for the exploration and for obtaining indicators in evolutional analysis of degradation in urban facades 

    Gibert Armengol, Vicente; Serrat Piè, Carles; Casas Rius, Joan Ramon (2014)
    Conference report
    Open Access
    The interest of this research is motivated by the huge constructive development in the building sector, which has led to an enormous volume of buildings worldwide over the last decades. This fact, as well as poor management ...
  • The relation type of affine algebras and algebraic varieties 

    Planas Vilanova, Francesc d'Assís (2015-11-01)
    Article
    Restricted access - publisher's policy
    We introduce the notion of relation type of an affine algebra and prove that it is well defined by using the Jacobi-Zariski exact sequence of Andre-Quillen homology. In particular, the relation type,is an invariant of an ...
  • Absolute order-of-magnitude reasoning applied to a social multi-criteria evaluation framework 

    Afsordegan, Arayeh; Sánchez Soler, Monica; Agell Jané, Núria; Aguado Chao, Juan Carlos; Gamboa Jimenez, Gonzalo (2015-04-27)
    Article
    Restricted access - publisher's policy
    A social multi-criteria evaluation framework for solving a real-case problem of selecting a wind farm location in the regions of Urgell and Conca de Barberá in Catalonia (northeast of Spain) is studied. This paper applies ...
