  • Study of signal integrity in Flex-Grid optical networks 

    Díez Navarro, Rubén (Universitat Politècnica de Catalunya, 2016-06)
    Treball Final de Grau
    Accés obert
    This project has studied the behaviour of optical signals in a FlexGrid network. More specifically, we have focused on finding the minimum distance that must exist between two signals such that we achieve a given BER, and ...
  • Evaluation of pre-filtering techniques for delay-spread compression in Wideband MISO systems 

    Comas Massague, Armand (Universitat Politècnica de Catalunya, 2017-01-08)
    Treball Final de Grau
    Accés obert
    Realitzat a/amb:  Aalborg universitet
    This thesis describes in quite depth the channel behaviour in wireless communications, pointing some of the complexities that communication systems must face. The document is then focused in Delay Spread Compression (DSC) ...
  • Study and implementation of manifold regularization techniques in neural networks 

    Tubau Pires, Miquel (Universitat Politècnica de Catalunya, 2017-01)
    Treball Final de Grau
    Accés obert
    Realitzat a/amb:  Università degli studi di Roma "La Sapienza"
    During the last years, semi-supervised learning has become one of the most important topics for research in machine learning. Dealing with the situation where few labeled training points are available, but a large number ...
  • A unity based validation model for rendering algorithms of motion tracked binaural recordings 

    Rendé Subias, Clara (Universitat Politècnica de Catalunya, 2017-01)
    Treball Final de Grau
    Accés obert
    In 2004, motion-tracked binaural (MTB) sound was introduced as a new method for capturing, recording and reproducing spatial sound. In November 2010, the Technische Universität Berlin (TUB) started to evaluate MTB recordings ...
  • Implantació d'un Pla Director de seguretat a una empresa real 

    Riba del Amo, Oriol (Universitat Politècnica de Catalunya, 2017-01)
    Treball Final de Grau
    Accés restringit per decisió de l'autor
    This work comprises the necessary steps of IT Security Plan development. Currently, the vast majority of organizations are aware of the increased risk of ciberatacs, both internal and external, increasingly sophisticated ...
  • Multimodal expression analysis 

    Aguilera Martínez, Carlos (Universitat Politècnica de Catalunya, 2017-01)
    Treball Final de Grau
    Accés obert
    El uso del reconocimiento de emociones ha ido en aumento en los últimos años, desde las redes sociales y los videojuegos a la investigación sobre la experiencia del cliente. Este hecho ha creado un interés en la comunidad ...
  • Opportunistic communications using software defined radio 

    Pérez Portero, Adrián (Universitat Politècnica de Catalunya, 2017-01-26)
    Treball Final de Grau
    Accés obert
    The increasing scarcity in the available spectrum is limiting the growth of high bandwidth applications. By exploiting licensed channels when they are unused, Opportunistic Communications aim to use the spectrum in a more ...
  • Reconocimiento de expresiones faciales mediante el uso de redes neuronales convolucionales 

    Sereno Rodriguez, Patricia (Universitat Politècnica de Catalunya, 2017-01)
    Treball Final de Grau
    Accés obert
    In recent years has appeared the need to be able to classify a person's facial expression automatically, that is, without making use of human intervention. For that task, this project is based on the research and development ...
  • Flexible microwave satellite payload using a software defined radio 

    Miguélez Gómez, Noemí (Universitat Politècnica de Catalunya, 2017-01)
    Treball Final de Grau
    Accés obert
    Cada vez resulta más obvio que los nanosatélites están siendo el impulso para diseñar todo tipo de experimentos que puedan llegar a desarrollar sistemas mucho más potentes, una vez probados y especializados los anteriores. ...
  • Extracción de cráneo en imágenes de resonancia magnética del cerebro utilizando una red neuronal convolucional 3D 

    Rodriguez Castello, David (Universitat Politècnica de Catalunya, 2017-01-25)
    Treball Final de Grau
    Accés obert
