    Article
    Accés restringit per política de l'editorial
    In order to correctly predict the kinematics of complex structures, analysis using three-dimensional finite elements (3DFEs) seems to be the best alternative. However, simulation of large multi-layered structures with many ...

    Report de recerca
    Accés obert
    The report discusses proposed solutions for constraint-based modelling, with special emphasis on constructive approaches. A new constructive scheme that overcomes a number of the present limitations is proposed. It is based ...

    Article
    Accés obert
    This paper deals with the formal description of what we call Fuzzy Temporal Propositions: propositions with explicitly expressed information of a temporal type. The set of syntactic rules that make a grammar up for defining ...
  • A large signal nonlinear MODFET model from small signal S-parameters 

    O'Callaghan Castellà, Juan Manuel; Beyer, Jb (1989)
    Text en actes de congrés
    Accés obert
    A general technique for predicting the MODFET large signal performance has been developed. The technique is based entirely on experimental data (small signal S-parameters at different biased points) and therefore is ...

    Pirrone, Vito (Universitat Politècnica de Catalunya, 2014-09-09)
    Projecte Final de Màster Oficial
    Accés obert
    The purpose of this work is to design a new version (called SNAVA+) of the architecture SNAVA, an SNN hardware emulator implemented on a XilinX Kintex-7 FPGA. SNAVA+ increases the capabilities of SNAVA in order to have a ...
  • A latent variable ranking model for content-based retrieval 

    Quattoni, Ariadna Julieta; Carreras Pérez, Xavier; Torralba, Antonio (Springer, 2012)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Since their introduction, ranking SVM models have become a powerful tool for training content-based retrieval systems. All we need for training a model are retrieval examples in the form of triplet constraints, i.e. examples ...
