Fernàndez Mora, Mª Àngels (Data de defensa: 2015-12-17)
The nearshore zone is plenty of 3D morphodynamic patterns resulting from the interaction of waves, currents and sediments. The dynamics of formation and evolution of these patterns is at present a controversial point in ...
Angelats Company, Eduard (Data de defensa: 2023-10-04)
(English) Hybrid or multi-sensor-based positioning has been a research topic actively investigated in the last decade. In this context, the possibility of using information extracted from imaging sensors, for positioning, ...
Dalmau Codina, Ramon (Data de defensa: 2019-06-25)
The growth in traffic increased the pressure on the environmental sustainability of air transport. In this context, many research effort has been devoted to minimise the environmental impact in the different phases of ...
Coma Company, Martí (Data de defensa: 2022-07-26)
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 ...
Skorobogatov, Georgy (Data de defensa: 2023-10-27)
(English) With the advance of UAV-related technology using several drones in the context of a single mission becomes more and more common. New problems and challenges appear as a result. When analyzing research works ...
Navarro Bosque, Javier (Data de defensa: 2022-03-17)
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 ...
Cojocaru, Elena-Ruxandra (Data de defensa: 2016-11-24)
As the evolutionary end-point of most main-sequence stars, white dwarfs can be used to infer important properties concerning the formation and evolution of the different Galactic stellar populations. Population synthesis ...
Gebbia, Jonathan Fernando (Data de defensa: 2021-10-06)
One of the most complex and unsolved problems in physics is the glass transition problem, in which the resulting state, the glass, exhibits unique and anomalous properties. During the transition, a kinetic freezing phenomenon ...
Monza, Emanuele (Data de defensa: 2016-12-19)
Metalloprotein are proteins containing metal ion cofactors. Compared to chemical catalysts, metalloproteins have a well-defined configuration around the active site which ensures higher specificity, selectivity and reaction ...
Guijarro Gamez, Grecia (Data de defensa: 2020-12-21)
In this Thesis, we report a detailed study of the ground-state properties of a set of quantum few- and many-body systems by using Quantum Monte Carlo methods. First, we introduced the Variational Monte Carlo and Diffusion ...
Ruiz, Guadalupe Natalia (Data de defensa: 2018-09-14)
Glassy phases play an important role in our daily life and in many industries such as the food, pharmaceutical, and construction and are responsible for certain vital mechanisms in living species. Whereas crystals are solid ...
Wang, Bingxia (Data de defensa: 2017-10-10)
The PhD project, entitled "Second harmonic generation in disordered nonlinear crystals: application to ultra-short laser pulse characterization", is devoted to the study of second harmonic generation in nonlinear ferroelectric ...
Krishnakumar, Vrinda (Data de defensa: 2022-09-29)
Persistent Scatterer interferometry (PSI) is a group of advanced differential interferometric Synthetic Aperture Radar (SAR) techniques used to measure and monitor terrain deformation. Sentinel-1 has improved the data ...
Mir Garcia, Pau (Data de defensa: 2024-01-16)
(English) In this thesis we study several mathematical objects that are essential to formulate and model physical systems. Applying the tools provided by differential geometry, we develop and analyze different mathematical ...
Flores García, Juan Carlos (Data de defensa: 2022-06-20)
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 ...
Medina Pardell, Judith (Data de defensa: 2021-11-30)
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 ...

This thesis focuses on the thermodynamic and crystallographic characterization of C60 solvates formed with small organic molecules (CBr2(CH3)2, CBr2Cl2, CBr2H2, CBrCl2H and CBrClH2) Chapter I provides an introduction ...
Chen, Jianlin (Data de defensa: 2021-04-23)
The motion of space objects is strongly nonlinear and non-integrable since it is not only affected by the Keplerian central gravity of the Earth, but also subjected to some complex perturbations. Either an accurate and ...
Wassie, Yismaw Abera (Data de defensa: 2023-07-24)
(English) The availability of RADAR images for monitoring Earth’s surface and its changes over time prompt the development of several interferometric SAR (InSAR) algorithms and methodologies. The Multi-temporal InSAR ...
