  • Analysis and design of a terminal sliding mode control applied to a step-down power converter 

    Masclans Serrat, Núria (Universitat Politècnica de Catalunya, 2019-06-25)
    Bachelor thesis
    Open Access
    Generally, step-down converters are controlled by a linear control called average model. This control technique results in a system behavior highly dependent on the working point. Therefore, non-linear techniques have been ...
  • Genetic toggle-switch in a multicellular feedback control strategy 

    Cristòbal, Enric (Universitat Politècnica de Catalunya, 2019-07-09)
    Bachelor thesis
    Open Access
    Synthetic biology is a field of study placed on the bioengineering world aiming to rationally engineer the biological processes that take place inside the living organisms to endow cells and organisms with new useful ...
  • Sentiment analysis of abusive texts

  • Effect of reactive oxygen species in the development of cardiac arrhythmias 

    Bosch Padrós, Miquel (Universitat Politècnica de Catalunya, 2019-06)
    Bachelor thesis
    Open Access
    Among all ions present in a cardiac cell, calcium is categorically the most important. It governs the contraction and relaxation of the heart chambers that enables pumping of blood throughout the body. Calcium mishandling ...
  • Optical sensor system for the extraction of movement and physiological parameters from disabled individuals 

    Sibuet Ruiz, Nicolás (Universitat Politècnica de Catalunya, 2019-06)

    Bachelor thesis
    Open Access
    Covenantee:  ALBA Synchrotron
    3D Hall probes designed and produced by ALBA Synchrotron are currently being used at ALBA magnetic measurements laboratory to carry out accurate magnetic characterization of magnets and insertion devices. In order to ...
  • Digital control of pre-turbulent flows in a Taylor-Couette device 

    Gil Bofill, Núria (Universitat Politècnica de Catalunya, 2019-07-09)
    Bachelor thesis
    Open Access
    Transition to turbulence is one of the oldest problems yet to be solved in physics and engineering. Certain fluid systems are known to undergo a laminar-turbulent transition through a deterministic route of laminar flows ...
