  • Optimization on industrial problems focussing on multi-player strategies 

    Coma Company, Martí (Universitat Politècnica de Catalunya, 2022-07-26)
    Doctoral thesis
    Open Access
    Algorithms (EA) are useful optimization methods for exploration of the search space, but they usually have slowness problems to exploit and converge to the minimum with accuracy. On the other hand, gradient based methods ...
  • Causal inference and forescasting methods for climate data nalysis 

    Silini, Riccardo (Universitat Politècnica de Catalunya, 2022-07-05)
    Doctoral thesis
    Open Access
    To advance time series forecasting we need to progress on multiple fronts. In this thesis, we develop algorithms to identify causal relations which allow to identify the driving processes containing useful information for ...
  • Network-based ionospheric gradient monitoring to support ground based augmentation systems 

    Caamaño Albuerne, María (Universitat Politècnica de Catalunya, 2022-07-12)
    Doctoral thesis
    Open Access
    The Ground Based Augmentation System (GBAS) is a local-area, airport-based augmentation of Global Navigation Satellite Systems (GNSSs) that provides precision approach guidance for aircraft. It enhances GNSS performance ...

    In this thesis, the results of different core-shell structures are presented after having been synthesized by the modified Stöber method, results of UV-Vis, SEM, TEM, XRD, among others, are shown, which determined the ...
  • Exact coherent structures in the transitional regime of shear and centrifugal flows 

    Ayats López, Roger (Universitat Politècnica de Catalunya, 2022-04-22)
    Doctoral thesis
    Open Access
    Turbulence is one of the major concerns for most technological problems involving fluid motion. Specially in aeronautics, a turbulent boundary layer results in structural stresses, vibrations and higher aircraft drag, ...
  • Dynamics and control for continuous low-thrust spacecraft near collinear libration points 

    Gao, Chen (Universitat Politècnica de Catalunya, 2022-05-18)
    Doctoral thesis
    Open Access
    Covenantee:   Xīběi Gōngyè Dàxué
    Due to the rich dynamic properties of the equilibria of the Restricted Three Body Problem (RTBP), the libration point orbits (LPOs) around them are ideal locations for scientific missions. Fortunately, these invariant ...
  • Computer modeling of the polarity and amoeboid motion of living cells 

    Moreno Ramos, Eduardo (Universitat Politècnica de Catalunya, 2022-05-30)
    Doctoral thesis
    Open Access
    Cell motility is important in many biological processes. Some examples relay in epidermal cells moving towards lesions during wound healing, neutrophils cells migrating towards sites of bacterial infection as part of the ...
  • GNSS-based global ionospheric maps : real-time combination, time resolution and applications on space weather monitoring 

    Liu, Qi (Universitat Politècnica de Catalunya, 2022-04-14)
    Doctoral thesis
    Open Access
    The research of this paper-based dissertation is focused on the Global Ionospheric Maps (GIMs) based on Global Navigation Satellite System (GNSS) including real-time combination, validation, time resolution and applications. ...
  • Organització espacial i temporal de la pluja a l'àrea metropolitana de Barcelona 

    Navarro Bosque, Javier (Universitat Politècnica de Catalunya, 2022-03-17)
    Doctoral thesis
    Open Access
    In order to avoid the catastrophes caused by intense or even moderately intense, rainfall episodes, it is essential to have as exhaustive a knowledge as possible of the behaviour of the same. We have a source of information ...
  • Smart control of light in edge-emitting lasers 

    Medina Pardell, Judith (Universitat Politècnica de Catalunya, 2021-11-30)
    Doctoral thesis
    Open Access
    The invention of the laser triggered the study of light-matter interactions. In turn, the advent of artificial structured materials on micro- and nanometer scales has become a fruitful playground to tailor the propagation ...
  • Models of stellar winds from X-ray bursts 

    Herrera, Yago (Universitat Politècnica de Catalunya, 2021-12-15)
    Doctoral thesis
    Open Access
    The study of stellar winds (SW) in the context of X-ray bursts (XRB) performed in this thesis has two main motivating issues. The first is whether or not the heavy elements produced from nucleosynthesis in XRBs can escape ...
  • Traffic synchronization with controlled time of arrival for cost-efficient trajectories in high-density terminal airspace 

    Sáez García, Raúl (Universitat Politècnica de Catalunya, 2021-10-01)
    Doctoral thesis
    Open Access
    The growth in air traffic has led to a continuously growing environmental sensitivity in aviation, encouraging the research into methods for achieving a greener air transportation. In this context, continuous descent ...
