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)
(English) Future Geosynchronous Synthetic Aperture Radar (GEOSAR) missions will provide permanent monitoring of continental areas of the planet with revisit times of less than 24 h. Several GEOSAR missions have been studied ...
Londoño López, Felipe César (Date of defense: 2002-07-22)
La tesis "Interficies de las Comunidades Virtuales", tiene el doble objetivo de explorar dos conceptos nuevos que surgen a partir de las conexiones en red: las interficies como lugar de comunicación entre dos o más personas ...
Peñalver Rojo, Domingo (Date of defense: 2019-05-31)
Investments in major transport infrastructure projects involve a significant mobilisation of economic resources both for construction and operation. In these projects, to assess the efficiency of the resources used, ...
Castillo Fuentealba, Carlos Ignacio (Date of defense: 2023-02-13)
(English) The purpose of the doctoral thesis is to study interior spaces - built in the old tradition of closed and contrasted architecture – relativized in their interior condition. In the classical opacity and the ...
Marques de Araújo, Luciano (Date of defense: 2013-10-25)
The aim of this investigation is to understand how international project teams enable mature multinational enterprises (MNEs) to cope with knowledge diversity and political activity, two well-known disruptive organizational ...
Dimogerontakis, Emmanouil (Date of defense: 2017-05-26)
The majority of the world's population does not have any or adequate Internet access. This implies that the Internet cannot provide universal service, reaching everyone without discrimination. Global access to the Internet ...
