  • Bringing social reality to multiagent and service architectures : practical reductions for monitoring of deontic-logic and constitutive norms 

    Álvarez Napagao, Sergio (Universitat Politècnica de Catalunya, 2016-02-08)
    Tesi
    Accés obert
    As distributed systems grow in complexity, the interactions among individuals (agents, services) of such systems become increasingly more complex and therefore more difficult to constrain and monitor. We propose to view ...
  • Gathering empirical evidence and building a business case for software reference architectures in industry 

    Martínez Fernández, Silverio Juan (Universitat Politècnica de Catalunya, 2016-06-23)
    Tesi
    Accés obert
    Background: Software reference architectures are becoming widely adopted by organizations that need to support the design and maintenance of software applications of a shared domain. For organizations that plan to adopt ...
  • Tree automata with constraints and tree homomorphisms

    Tesi
    Accés obert
    In the field of computer animation the process of creating an animated character is usually a long and tedious task. An animation character is usually efined by a 3D mesh (a set of triangles in the space) that gives its ...
  • Towards more reliable feature evaluations for classification 

    Prat Masramon, Gabriel (Universitat Politècnica de Catalunya, 2016-02-01)
    Tesi
    Accés obert
    In this thesis we study feature subset selection and feature weighting algorithms. Our aim is to make their output more stable and more useful when used to train a classifier. We begin by defining the concept of stability ...
  • A dynamic adaptive framework for improving case-based reasoning system performance 

    Orduña, Fernando (Universitat Politècnica de Catalunya, 2016-02-05)
    Tesi
    Accés obert
    An optimal performance of a Case-Based Reasoning (CBR) system means, the CBR system must be efficient both in time and in size, and must be optimally competent. The efficiency in time is closely related to an efficient and ...
