Optimization on industrial problems focussing on multi-player strategies
(Universitat Politècnica de Catalunya, 2022-07-26)
Doctoral thesis
Open AccessAlgorithms (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
(Universitat Politècnica de Catalunya, 2022-07-05)
Doctoral thesis
Open AccessTo 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
(Universitat Politècnica de Catalunya, 2022-07-12)
Doctoral thesis
Open AccessThe 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 ... -
Síntesis de nanoparticulas multifuncionalizadas tipo Core-Shell mediante rutas quimicas
(Universitat Politècnica de Catalunya, 2022-06-20)
Doctoral thesis
Open AccessIn 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
(Universitat Politècnica de Catalunya, 2022-04-22)
Doctoral thesis
Open AccessTurbulence 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
(Universitat Politècnica de Catalunya, 2022-05-18)
Doctoral thesis
Open Access
Covenantee: Xīběi Gōngyè DàxuéDue 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
(Universitat Politècnica de Catalunya, 2022-05-30)
Doctoral thesis
Open AccessCell 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
(Universitat Politècnica de Catalunya, 2022-04-14)
Doctoral thesis
Open AccessThe 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
(Universitat Politècnica de Catalunya, 2022-03-17)
Doctoral thesis
Open AccessIn 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
(Universitat Politècnica de Catalunya, 2021-11-30)
Doctoral thesis
Open AccessThe 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
(Universitat Politècnica de Catalunya, 2021-12-15)
Doctoral thesis
Open AccessThe 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
(Universitat Politècnica de Catalunya, 2021-10-01)
Doctoral thesis
Open AccessThe 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 ...
