Almeida, Jessica Oliveira de (Date of defense: 2022-07-28)
Quantum optics experiments are currently the most advanced techniques to under- stand, verify and simulate quantum phenomena. However, to access all the perfor- mance available in quantum states of light, one needs to ...
Abellán Sánchez, Carlos (Date of defense: 2018-06-19)
Randomness is one of the most intriguing, inspiring and debated topics in the history of the world. It appears every time we wonder about our existence, about the way we are, e.g. Do we have free will? Is evolution a result ...
Hauke, Philipp Hans-Jürgen (Date of defense: 2013-04-05)
Many outstanding problems in quantum physics, such as high-Tc superconductivity or quark confinement, are still - after decades of research - awaiting commonly accepted explanations. One reason is that such systems are ...
León Montiel, Roberto de Jesús (Date of defense: 2014-09-30)
For many years, the fields of quantum optics and biology have rarely shared a common path. In quantum optics, most of the concepts and techniques developed over the years stand for systems where only a few degrees of freedom ...
Camphausen, Robin (Date of defense: 2023-04-12)
(English) Entangled photon pairs can enhance optical imaging capabilities. Phase imaging allows detecting fine detail of transparent samples without potentially invasive fluorescent labelling, and here entanglement enables ...
Blasco Coll, Andreu (Date of defense: 2023-09-27)
(English) Quantum computers use the laws of quantum mechanics to do complex operations that classical computers can't solve. Quantum computers and other physical quantum systems require quantum information to be completely ...
Guisado Gámez, Joan (Date of defense: 2017-09-28)
Query expansion techniques aim at improving the results achieved by a user's query by means of introducing new expansion terms, called expansion features. Expansion features introduce new concepts that are semantically ...
Wu, Haiqing (Date of defense: 2023-07-28)
(English) Understanding the triggering mechanisms of induced seismicity remains one of the most critical challenges in geo-energy applications. This Thesis aims at assessing (1) fault stability and induced seismicity ...
Pérez Gracia, María de la Vega (Date of defense: 2001-10-26)
.<br/>El georradar es una herramienta cada vez más utilizada en diferentes ámbitos geológicos, medioambientales y de Ingeniería Civil, así como en estudios de caracterización de yacimientos arqueológicos y de diagnóstico ...
Pous Solà, Marc (Date of defense: 2015-04-24)
In the Electromagnetic Compatibility research area, an unsolved interference problem is the measurement and evaluation of the distortion produced by radiated transient disturbances on digital communication systems. This ...
Balcells Ventura, Jordi (Date of defense: 2011-05-20)
Els serveis de telecomunicacions i sistemes radar estan migrant a freqüències mil•limètriques (MMW), on es disposa d 'una major amplada de banda i conseqüentment d'una major velocitat de transmissió de dades. Aquesta ...
Albajar Viñas, Ferran (Date of defense: 2001-06-14)
The understanding and modelling of heat and radiation transport in tokamak plasmas is essential in order to progress in the development of thermonuclear fusion towards a practical energy source which meets all the future ...
Guerra Gómez, Rolando (Date of defense: 2023-05-19)
(English) The Fifth-Generation (5G) of cellular networks significantly increases the performance and flexibility of the offered services to users and service providers. The strict network requirement of 5G use cases has ...
Gómez, Ismael (Date of defense: 2013-12-19)
The aim of this thesis is defining and developing the concept of an efficient management of radio and computing resources in an SDR cloud. The SDR cloud breaks with today's cellular architecture. A set of distributed ...
Querol Borràs, Jorge (Date of defense: 2018-11-09)
Radio-Frequency Interference (RFI) signals are undesired signals that degrade or disrupt the performance of a wireless receiver. RFI signals can be troublesome for any receiver, but they are especially threatening for ...
Tarongí Bauzá, José Miguel (Date of defense: 2013-03-06)
Microwave radiometry field has been increasing its performance with higher accuracy measurements, leading to a more presence in the remote sensing field. Several space-borne, air-borne and ground-based radiometers have ...
Albonda, Haider Daami R. (Date of defense: 2020-07-21)
The thesis focuses on the provision of cellular vehicle-to-everything (V2X) communications, which have attracted great interest for 5G due to the potential of improving traffic safety and enabling new services related to ...
Koutlia, Aikaterini (Date of defense: 2016-05-18)
