  • Analysis of class C G-protein coupled receptors using supervised classification methods 

    König, Caroline Leonore (Universitat Politècnica de Catalunya, 2018-10-30)
    Tesi
    Accés obert
    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
