    • Dynamics and bifurcations in a simple quasispecies model of unstable tumorigenesis 

      Castillo Blanco, Vanessa (Universitat Politècnica de Catalunya, 2014-10)
      Bachelor thesis
      Open Access
      Cancer is a complex disease and thus is complicated to model. However, simple models that describe the main processes involved in tumoral dynamics, e.g., competition and mutation, can give us clues about cancer behaviour, ...

    • Modelling attentional biases in bistable perception 

      Vilardell Barnosell, Marina (Universitat Politècnica de Catalunya, 2019-07)
      Master thesis
      Open Access
      Binocular rivalry is a type of bistable perception phenomena that arises when the eyes are unable to combine ambiguous stimuli into a unique image. It promotes a competition process between the visual interpretations ...

    • Modelling the n - body chain collision problem
