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 ...
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 ...
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 ...
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 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 ...
Fita Borrell, Lluis (Date of defense: 2008-05-23)
S'han estudiat diverses ciclogènesis mediterrànies mitjançant el model atmosfèric MM5,<br/>la inversió de vorticitat potencial per peces i la tècnica de la separació de factors. Els<br/>resultats mostren com a agents per ...
Palmer García, Margarita (Date of defense: 2012-12-14)
This work compiles the results of the analysis of hydrographical data collected in January 2008 over the western sector of the South Scotia Ridge (SSR). The cruise was carried out on board R/V Hespérides in the framework ...
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 ...
Rodríguez Enríquez, Alejandra (Date of defense: 2019-11-29)
[eng] This thesis investigates and quantifies the impacts caused by climate change in the coasts of Balearic Islands (western Mediterranean Sea) from both a physical and an economic perspective. Two physical mechanisms ...
Appeltant, Lennert (Date of defense: 2012-05-22)
Today, except for mathematical operations, our brain functions much faster and more efficient than any supercomputer. It is precisely this form of information processing in neural networks that inspires researchers to ...
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 ...

Jiménez Cortés, Maria Antònia (Date of defense: 2005-12-12)
La capa límit atmosfèrica és l'àrea directament influenciada per la presència de la superfície de la terra i la seva alçada és d'uns centenars de metres a uns pocs quilòmetres. Durant el vespre, el refredament radiatiu ...
Chaparro González, Daniel (Date of defense: 2020-01-17)
[cat] El present treball constitueix un estudi sobre la generació i control de polsos optics en diferents tipus de lasers de semiconductor i el seu potencial aplicació a sistemes de mesures a distancia. En primer lloc, ...
David Hertel, Julian (Date of defense: 2019-07-23)
[eng] According to several studies, the installed capacity of solar thermal collectors to provide heat for industrial processes is going to increase significantly during the next decades. The great variety of designs and ...
Capó Truyols, María Esther (Date of defense: 2020-01-22)
[eng] The transition from mesoscale to submesoscale dynamics is investigated in the western Mediterranean Sea (WMed) using a set of ROMS model simulations. The research is structured in a series of sequential stages ...
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 ...
Rial Lesaga, Samuel (Date of defense: 2019-10-11)
[eng] In this thesis we will study vertical oscillations in a potential arcade under the approximation of a zero- plasma, when di erent density pro les are considered. On one hand we will focus on the time-dependent ...
Suenaga Portuguès, Kay (Date of defense: 2008-12-17)
En aquesta tesi s'ha desenvolupat una tècnica de test que permet testar un LNA i un mesclador, situats en el capçal RF d'un receptor CMOS, en una configuració de test semblant al mode normal de funcionament.<br/>La circuiteria ...
Alic, Daniela Delia (Date of defense: 2009-09-18)
