    Projecte Final de Màster Oficial
    Accés obert
    In many coupled fluid-structure problems of practical interest the domain of at least one of the problems evolves in time. The most often applied approach to deal with such motion in numerical methods is the use of the ...
  • Approximate formulae for a logic that capture classes of computational complexity

    Article
    Accés obert
    This paper presents a syntax of approximate formulae suited for the logic with counting quantifiers SOLP. This logic was formalised by us in [1] where, among other properties, we showed the following facts: (i) In the ...
  • Approximate fuzzy preorders and equivalences 

    Boixader Ibáñez, Dionís; Recasens Ferrés, Jorge (2009)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Although Fuzzy Preorders and Fuzzy Equivalences are well established types of fuzzy relations, they are defined in terms of properties to be fulfilled in a crisp way. In this paper we relax those requirements by making ...
  • Approximate nearest neighbour search with the fukunaga & narendra algorithm

    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a model-based hierarchical particle filtering algorithm to estimate the pose and anthropometric parameters of humans in multi-view environments. Our method incorporates a novel likelihood measurement ...
  • Approximate policy iteration using regularized Bellman residuals minimization 

    Esposito, Gennaro; Martín Muñoz, Mario (Taylor & Francis, 2016)
    Article
    Accés obert
    Reinforcement Learning (RL) provides a general methodology to solve complex uncertain decision problems, which are very challenging in many real-world applications. RL problem is modeled as a Markov Decision Process (MDP) ...

    Accés obert
    Realitzat a/amb:  Akademia Górniczo-Hutnicza im. S. Staszica w Krakowie
    The implementation of a distributed electronic art platform with a considerable amount of data available involves some technical challenges. Due to the lack of a common European platform for media art, the European ...

  • Approximating arbitrary fuzzy subsets by extensional ones 

    Mattioli Aramburu, Gabriel; Recasens Ferrés, Jorge (2015-06-01)
    Article
    Accés obert
    An interesting problem within the theory of indistinguishability operators is how to approximate an arbitrary fuzzy subset by a similar extensional one. In this paper, we aim to solve this question and provide three methods ...

  • Approximating layout problems on random sparse graphs 

    Díaz Cort, Josep; Petit Silvestre, Jordi; Serna Iglesias, María José; Trevisan, Marco (1998-07)
    Report de recerca
    Accés obert
    We show that, with high probability, several layout problems are approximable within a constant for random graphs drawn from the standard Gnp model with p=c/n for some constant c. Our results establish that, in fact, ...
  • Approximating proximities by similarities

    Text en actes de congrés
