Forteza Ferrer, Pep (Date of defense: 2013-02-11)
Inici de l’estudi de l’efecte de les col•lisions entre ions i neutres en l’esmorteïment d’ones magnetohidrodinàmiques. Es considera un plasma parcialment ionitzat, infinit i homogeni, i s’analitza l’esmorteïment temporal ...
Barceló Adrover, Salvador (Date of defense: 2013-12-19)
En base als reptes sorgits a conseqüència de l'escalat de la tecnologia, la present tesis desenvolupa i analitza un conjunt d'eines orientades a avaluar la sensibilitat a la propagació d'esdeveniments SET en circuits ...
Grabowicz, Przemyslaw Adam (Date of defense: 2014-01-10)
This thesis is devoted to quantitative description, analysis, and modeling of complex social systems in the form of online social networks. Statistical patterns of the systems under study are unveiled and interpreted using ...
Selingardi Matias, Fernanda (Date of defense: 2014-03-18)
Anticipated Synchronization (AS) is a form of synchronization that occurs when a unidirectional influence is transmitted from an emitter to a receiver, but the receiver system leads the emitter in time. This counterintuitive ...
Martínez García, Ricardo (Date of defense: 2014-06-25)
Esta tesis doctoral se centra en la aplicación de la física estadística del no equilibrio al estudio de problemas ecológicos de diferente naturaleza. En primer lugar se desarrollan modelos teóricos para explicar la formación ...
Hicke, Konstantin (Date of defense: 2014-07-03)
The work in this thesis is focused on the complex dynamics of semiconductor laser (SL) devices which receive time-delayed feedback from an external cavity or are delay-coupled with a second semiconductor laser. We ...
Amores Maimó, Angel Miguel (Date of defense: 2014-07-09)
The Balearic Islands, located in the Western Mediterranean Sea, are the natural limit between the Balearic subbasin, at the noth and the Algerian subbasin, at the south. Previous studies based on hydrographic data have ...
Escudier, Romain (Date of defense: 2015-01-21)
Mesoscale eddies are relatively small structures that dominate the ocean variability and have large impact on large scale circulation, heat fluxes and biological processes.In the western Mediterranean Sea, a high number ...
Tous Nadal, Maria (Date of defense: 2015-09-18)
Medicanes are a rare and physically unique type of Mediterranean cyclone. They show similarities with tropical cyclones with regard to their development (based on the thermodynamical disequilibrium between the warm sea ...
Martínez Asensio, Adrián (Date of defense: 2015-09-28)
This thesis aims at quantitatively characterizing the recent (last few decades) and future climate variability of marine climate in the Western Mediterranean Sea and the North Atlantic Ocean. Namely it focuses on sea level ...
Porte Parera, Javier (Date of defense: 2015-11-30)
Introduction: The present thesis is devoted to the study of semiconductor lasers subject to delayed optical feedback and coupling. The complex spectral and dynamical properties of these systems have been investigated ...
Oliver Andreu, Neus (Date of defense: 2015-12-16)
- Introducció Photonic systems are powerful test-beds for the investigation of complex dynamics emerging from delays in feedback or coupling. The aim of this thesis was to study two relevant properties of photonic delay ...
Carro Patiño, Adrián (Date of defense: 2016-09-29)
The main purpose of this thesis is to contribute to the understanding of how complex collective behaviors emerge in social and economic systems. To this end, we use a combination of mathematical analysis and computational ...
Martínez Llinàs, Jade (Date of defense: 2016-11-15)
Aquesta tesi doctoral se centra en l’estudi teòric i numèric de sistemes fotònics amb retroacció i múltiples línies de retard, en el límit en el que els temps de retard són molt més grans que les escales de temps ...
Jiménez Forteza, Francisco (Date of defense: 2017-09-05)
[eng]Throughout history, human beings have received and interpreted information from distant stars and galaxies through electromagnetic waves (light). Until 2015 this was the dominant way for observing astrophysical ...
Alomar Barceló, Miquel Lleó (Date of defense: 2017-09-11)
[cat]Inspirades en la forma en què el cervell processa la informació, les xarxes neuronals artificials (XNA) es crearen amb l’objectiu de reproduir habilitats humanes en tasques que són difícils de resoldre mitjançant la ...
Martínez Gómez, David (Date of defense: 2018-01-17)
The solar atmosphere is a highly dynamic environment in which a huge diversity of waves and instabilities has been detected. The matter in that region is in plasma state, and thus is affected by the presence of electromagnetic ...
Oliver Gelabert, Antoni (Date of defense: 2018-02-16)
Introducción El acelerado ritmo al que se genera y crece la información en la sociedad actual y la posible llegada de la tecnología de transistor a sus límites de tamaño exige la puesta en marcha de soluciones para el ...
Sousa Sena, André Luis (Date of defense: 2018-02-19)
[eng] The main objective proposed in this doctoral thesis was focused on the study and development of a solution for the remote sensing of the submarine topographic relief, using for this, inexpensive equipment. Here we ...
Rius Gibert, Joan Maria (Date of defense: 2019-04-05)
[eng] Shear strengthening of existing structures is often required as shear failures in reinforced concrete (RC) members are associated with brittle collapses, it being essential to avoid this kind of failure. This thesis ...
