Leon Medina, Jersson Xavier (Date of defense: 2023-10-06)
(English) In the last years, the condition monitoring of structures has evolved and improved using technologies such as artificial intelligence, sensor networks, and industry 4.0 because of the multiple advantages these ...
Llort Sánchez, Germán M. (Date of defense: 2015-11-03)
With ever more powerful machines being constantly deployed, it is crucial to manage the computational resources efficiently. This is important both from the point of view of the individual user, who expects fast results; ...
Selseleh Jonban, Mansour (Date of defense: 2023-06-09)
(English) Nowadays, distributed energy resources are widely used to supply demand in micro grids especially in green buildings. These resources are usually connected by using power electronic converters, which act as ...
Vaquero Martínez, José M. (Date of defense: 2013-02-22)
La interacción microorganismo–hormigón es un proceso que, debido a la naturaleza porosa del hormigón, lo hace susceptible de ser colonizado por los microorganismos presentes en prácticamente todos los hábitats. Esta ...
Maymó Camós, Marc (Date of defense: 2007-11-29)
Les interaccions no lineals de segon ordre són, probablement, uns dels processos de l'òptica no lineal més utilitzats i rellevants en quant a les seves aplicacions. Aquestes interaccions només són eficients en materials ...
Alonso López, Joan Francesc (Date of defense: 2011-09-29)
Most biological systems are complex and consist of several interconnected parts whose links can contain additional information which can be hidden from the observer. As a result of the interactions between elements, emergent ...
Font Capó, Jordi (Date of defense: 2012-09-26)
A number of problems, e.g. sudden inflows are encountered during tunneling under the piezometric level, especially when the excavation crosses high transmissivity areas. These inflows may drag materials when the tunnel ...
Pujades Garnes, Estanislao (Date of defense: 2013-11-27)
Underground constructions below the water table may be problematic if the role of groundwater is not properly acknowledged. Difficulties worsen in urban environments. Two aspects should be taken into account in the interaction ...
Aguareles Carrero, Maria (Date of defense: 2007-07-23)
Molts sistemes físics tenen la propietat que la seva dinàmica ve definida per algun tipus de difussió espaial en competició amb un fenòmen de reacció, com per exemple en el cas de dos components químics que reaccionen al ...
Napolitano, Mario (Date of defense: 2014-02-07)
In this manuscript we present an experimental and theoretical investigation of quantum-noise-limited measurement by nonlinear interferometry, or from another perspective, quantum-noise-limited interaction-based measurement. ...
Pegueroles Neyra, Marta (Date of defense: 2009-09-16)
El conocimiento de las interacciones entre célula/proteína/biomaterial es fundamental para la ingeniería de superficies debido a las numerosas aplicaciones biomédicas y biotecnológicas que se están desarrollando así como ...
Galí Tàpias, Martí (Date of defense: 2012-12-18)
The production and subsequent emission of volatile compounds is one of the numerous ways by which microbial plankton participate in the cycling of elements and influence the Earth's climate. Dimethylsulfide (DMS), produced ...
Surinyac i Albareda, Jordi (Date of defense: 2016-02-05)
Present systems for the acquisition of medical images are providing better and better resolution images which end up in bigger amounts of data, even in scenarios with learning or training purposes. Interactive inspection ...
Borralleras Mas, Pere (Date of defense: 2019-11-15)
The presence of clays in the sands used for concrete production interferes with the development of the fluidity of concrete, producing an instantaneous slump loss just after batching and the premature loss of fluidity. ...
Sánchez López, Sergio (Date of defense: 2003-10-07)
Las redes de transporte se mueven hacia un modelo de redes formadas por routers IP/MPLS (Internet Protocol/Multiprotocol Laebel Switching) de altas prestaciones interconectadas a través redes troncales inteligentes. ...
Jin, Chen (Date of defense: 2018-10-31)
This thesis contributes to the fabrication technology of c-Si solar cells on thin substrates based on Interdigitated Back-Contacted (IBC) structures. The potential of this structure to obtain high efficiencies is well-known. ...
López Rodríguez, Gema (Date of defense: 2016-12-05)
The goal of this thesis is the fabrication of high-efficiency interdigitated back-contact (IBC) c-Si solar cell at low temperature and low-cost manufacturing technology. This thesis proposes a new concept and at the same ...
Martín Alemany, Francisco (Date of defense: 2015-07-14)
This PhD dissertation is focused on the use of the opportunity signals from the Global Navigation Satellite Systems (GNSS), that scatter-off the Earth's surface for perform ocean mesoscale altimetry (the so called GNSS-R ...
Nicolás Álvarez, Jorge (Date of defense: 2023-05-16)
