  • Curat tèrmic i fotocurat de resines epoxi per al control químic de la contracció i millora de la degradabilitat 

    Fernández Francos, Xavier (Universitat Politècnica de Catalunya, 2009-07-10)
    Tesi
    Accés obert
    S’ha estudiat la copolimerització de resines epoxi amb una spirobislactona com a comonòmer per tal de controlar la contracció química durant el curat i millorar la seva degradabilitat per tal d’afavorir la seva recuperació ...
  • Estimating and understanding motion : from diagnostic to robotic surgery 

    Avilés Rivero, Angélica Ivone (Universitat Politècnica de Catalunya, 2017-05-18)
    Tesi
    Accés obert
    Estimating and understanding motion from an image sequence is a central topic in computer vision. The high interest in this topic is because we are living in a world where many events that occur in the environment are ...
  • Simulating quantum measurements and quantum correlations 

    Guerini de Souza, Leonardo (Universitat Politècnica de Catalunya, 2018-01-29)
    Tesi
    Accés obert
    This PhD thesis is focused on the quantum measurement simulability problem, that is, deciding whether a given measurement can be simulated when only a restricted subset of measurements is accessible. We provide an operational ...
  • Le Corbusier : la forma acústica 

    Coll López, Jaime (Universitat Politècnica de Catalunya, 1994-05-13)
    Tesi
    Accés obert
    La tesis, con el título "Le Corbusier: la forma acústica", consiste en un trabajo de investigación sobre la obra de Le Corbusier. Este trabajo se centra en su producción como dibujante y pintor a partir de un cuidadoso y ...
  • Simulation tools for biomechanical applications with PGD-based reduced order models 

    Zou, Xi (Universitat Politècnica de Catalunya, 2018-03-12)
    Tesi
    Accés obert
    Numerical simulation tools are generally used in all modern engineering fields, especially those having difficulties in performing large number of practical experiments, such as biomechanics. Among the computational methods, ...
  • Spontaneous parametric down-conversion sources for generation of atom-resonant quantum light 

    Zielińska, Joanna Ada (Universitat Politècnica de Catalunya, 2018-03-19)
    Tesi
    Accés obert
    This thesis studies different designs of optical parametric oscillators as sources of atom-resonant quantum light resonant with the rubidium D1 line.We analyze the mode structure and filtering techniques in a conventional ...
  • Fluid-electro-mechanical model of the human heart for supercomputers 

    Santiago, Alfonso (Universitat Politècnica de Catalunya, 2018-03-22)
    Tesi
    Accés obert
    The heart is a complex system. From the transmembrane cell activity to the spatial organization in helicoidal fibers, it includes several spatial and temporal scales. The heart muscle is surrounded by two main tissues that ...
  • Dynamic modelling and control schemes for current-source resonant converters 

    Ghahderijani, Mohammad Moradi (Universitat Politècnica de Catalunya, 2018-10-09)
    Tesi
    Accés obert
    This thesis focuses on the control methods applied to current source resonant converters, especially in two different applications of switching power supplies and wire-less power transfer systems. In fact, the existing ...
  • A study of cortical network models with realistic connectivity 

    Vegué, Marina (Universitat Politècnica de Catalunya, 2018-03-23)
    Tesi
