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)
In this thesis we address several analytical and numerical problems related with the general relativistic study of black hole space-times and boson stars. <br/>We have developed a new centered finite volume method based ...
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 ...
