  • Approximating proximities by similarities 

    Garmendia Salvador, Luis; Recasens Ferrés, Jorge (Univ. Malaga, 2008)
    Text en actes de congrés
    Accés obert
    In this paper an algorithm to find a similarity close to a proximity or tolerance relation R is given. The obtained similarity is closer to R than its transitive closure or any transitive opening of R.
  • Approximating scheduling problems in parallel 

    Serna Iglesias, María José; Xhafa Xhafa, Fatos (1997-04)
    Report de recerca
    Accés obert
    We show how to approximate in NC the problem of Scheduling Unrelated Parallel Machines, for a fixed number of machines. We develop a (2+epsilon)-approximate parallel algorithm for the problem. Our approach shows how to ...
  • Approximating the DTD of a set of XML documents

    Report de recerca
    Accés obert
    The WWW contains a huge amount of documents. Some of them share the subject, but are generated by different people or even organizations. To guarantee the interchange of such documents, we can use XML. This allows to share ...
  • Approximating the expressive power of logics in finite models 

    Arratia Quesada, Argimiro Alejandro; Ortiz, Carlos E. (Springer, 2004)
    Text en actes de congrés
    Accés obert
    We present a probability logic (essentially a first order language extended with quantifiers that count the fraction of elements in a model that satisfy a first order formula) which, on the one hand, captures uniform circuit ...
  • Approximating the permanent is in RNC 

    Díaz Cort, Josep; Serna Iglesias, María José; Spirakis, Paul George (1995-04)
    Report de recerca
    Accés obert
    In this work we look into the parallelization (in the NC sense) of the Markov Chain approach to almost random generation, as described by Sinclair (1993). We give a RNC almost uniform generator for perfect matchings in ...

  • Approximation heuristics and benchmarkings for the MinLA problem 

    Petit Silvestre, Jordi (1997-09)
    Report de recerca
    Accés obert
    This paper presents heuristic approximation algorithms and methods to find lower bounds to approximate the Minimum Linear Arrangement problem and evaluates and compares experimentaly their behaviour when they are applied ...

    Article
    Accés restringit per política de l'editorial
    This paper describes a method to obtain a closed surface that approximates a general 3D data point set with nonuniform density. Aside from the positions of the initial data points, no other information is used. Particularly, ...
  • Approximation of face images by analytical model 

    Zhan, Yu (Universitat Politècnica de Catalunya / École polytechnique fédérale de Lausanne, 2012-02)
    Projecte/Treball Final de Carrera
    Accés obert
    English: in this thesis, we address the problem of learning a face manifold model from an input data, consisting of 2D face images such that the input images can be approximated well using the learned manifold. We compute ...

    Las biomembranas constituyen la estructura de separación fundamental en las celulas animales, y son importantes en el diseño de sistemas bioinspirados. Su simulación presenta desafíos, especialmente cuando ésta implica ...
  • Approximation of proximities by aggregating T-indistinguishability operators 

    Garmendia, L.; Recasens, J. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2007)
    Article
    Accés obert
    For a continuous Archimedean t-norm T a method to approximate a proximity relation R (i.e. a reflexive and symmetric fuzzy relation) by a T-transitive one is provided. It consists of aggregating the transitive closure R ...
  • Approximation of the inductionless MHD system with finite element techniques
