  • High-precision computation of uniform asymptotic expansions for special functions 

    Navas Palencia, Guillermo (Universitat Politècnica de Catalunya, 2019-07-22)
    Doctoral thesis
    Open Access
    In this dissertation, we investigate new methods to obtain uniform asymptotic expansions for the numerical evaluation of special functions to high-precision. We shall first present the theoretical and computational fundamental ...
  • Towards adaptative monitoring for self-adaptative systems 

    Zavala, Edith (Universitat Politècnica de Catalunya, 2019-07-05)
    Doctoral thesis
    Open Access
    Nowadays, most of the approaches supporting self-adaptive systems (SASs) rely on static feedback control loops, for managing their adaptation process. One of the most popular feedback loops is the MAPE-K loop. In this loop, ...
  • Synthesis of variability-tolerant circuits with adaptive clocking 

    Moreno Vega, Alberto (Universitat Politècnica de Catalunya, 2019-03-08)
    Doctoral thesis
    Open Access
    Improvements in circuit manufacturing have allowed, along the years, increasingly complex designs. This has been enabled by the miniaturization that circuit components have undergone. But, in recent years, ...
  • Logic decomposition and adaptive clocking for the optimization of digital circuits 

    Machado, Lucas (Universitat Politècnica de Catalunya, 2019-02-21)
    Doctoral thesis
    Open Access
    Over the course of 60 years, since the invention of the integrated circuit (IC), exponential improvements in cost, performance and power consumption were observed. Such advances have been strongly linked with the continuous ...
  • Learning latent variable models : efficient algorithms and applications 

    Ruffini, Matteo (Universitat Politècnica de Catalunya, 2019-02-14)
    Doctoral thesis
    Open Access
    Learning latent variable models is a fundamental machine learning problem, and the models belonging to this class - which include topic models, hidden Markov models, mixture models and many others - have a variety of ...
  • Light methods for conformance checking of business processes 

    Taymouri, Farbod (Universitat Politècnica de Catalunya, 2018-12-21)
    Doctoral thesis
    Open Access
    Conformance Checking is a new research discipline devoted to identify deviations between business process models and their real executions. Identifying deviations boils down to the notion of alignment conceptually. An ...
  • A hybrid approach for item collection recommendations : an application to automatic playlist continuation 

    Gkatzioura, Anna (Universitat Politècnica de Catalunya, 2018-11-23)
    Doctoral thesis
    Open Access
    Current recommender systems aim mainly to generate accurate item recommendations, without properly evaluating the multiple dimensions of the recommendation problem. However, in many domains, like in music, where items are ...
  • Analysis of class C G-protein coupled receptors using supervised classification methods 

    König, Caroline Leonore (Universitat Politècnica de Catalunya, 2018-10-30)
    Doctoral thesis
    Open Access
    G protein-coupled receptors (GPCRs) are cell membrane proteins with a key role in regulating the function of cells. This is the result of their ability to transmit extracellular signals, which makes them relevant for ...
  • Human-smart rollator interaction for gait analysis and fall prevention using learning methods and the i-Walker 

    Cortés Martínez, Atia (Universitat Politècnica de Catalunya, 2018-07-20)
    Doctoral thesis
    Open Access
    The ability to walk is typically related to several bio-mechanical components that are involved in the gait cycle (or stride), including free mobility of joints, particularly in the legs; coordination of muscle activity ...
  • Realistic reconstruction and rendering of detailed 3D scenarios from multiple data sources 

    Argudo Medrano, Óscar (Universitat Politècnica de Catalunya, 2018-07-19)
    Doctoral thesis
    Open Access
    During the last years, we have witnessed significant improvements in digital terrain modeling, mainly through photogrammetric techniques based on satellite and aerial photography, as well as laser scanning. These techniques ...
  • A soft computing decision support framework for e-learning 

    Castro Espinoza, Félix (Universitat Politècnica de Catalunya, 2018-06-21)
    Doctoral thesis
    Open Access
    Supported by technological development and its impact on everyday activities, e-Learning and b-Learning (Blended Learning) have experienced rapid growth mainly in higher education and training. Its inherent ability to break ...
  • Using natural language processing for question answering in closed and open domains 

    Latifi, Majid (Universitat Politècnica de Catalunya, 2018-05-25)
    Doctoral thesis
    Open Access
    With regard to the growth in the amount of social, environmental, and biomedical information available digitally, there is a growing need for Question Answering (QA) systems that can empower users to master this new wealth ...
