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. ...
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 ...
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 ...
(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 ...
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 ...
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, ...
(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 ...
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 ...
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 ...
This thesis explores the in-between spaces of the contemporary city, and the role they have in promoting urban togetherness through interstitial practice. By looking at different processes that take place in the borderlands ...
Aquesta tesi tracta sobre tècniques d'anàlisi de supervivència en situacions amb múltiples esdeveniments i patrons complexes de censura. Proposem una nova metodologia per tractar la situació de riscos semi-competitius quan ...
"Inhabited intervals" is a research about the transition space in collective housing, specifically about the intermediate space located on the way from home to the street. After the work done by Team 10 between the fifties ...
This PhD thesis is a deep research on the architectural evolution of the most representative municipal markets in Catalonia and Valencia , from its origins to the present day. It includes an extensive comparison of all the ...
There has been interest over the last few decades in Barcelona for buildings in urban cores that have outlived their original purpose. To take advantage of the heritage of these buildings, both public and private sectors ...
(English) There is a broad consensus on the need to drive urban intervention public policies with the purpose of promoting more inclusive, sustainable, balanced and diverse cities. Urban intervention is not neutral; it has ...
La Selva Lacandona de Chiapas, al sureste de la República Mexicana, es una región de 1'800.000 hectáreas de alto valor ambiental. Determinada por las características físicas del ecosistema selvático, ha sido un escenario ...
The process of landscape restoration in highly polluted areas is influenced by complex interactions between a variety of environmental elements; these are interconnected through the comprehensive medium of the landscape ...
Semiconductor lasers in high-power regime typically manifest a poor beam quality due to its asymmetric beam divergence and its large beam quality factor (M2). The emission along one of the transverse directions (slow axis) ...
The development of synthetic bone substitutes with enhanced osteogenic properties is urged by the global ageing population. Sintered calcium-phosphate (CaP) ceramics are the most widely used synthetic biomaterials for bone ...
Quantum mechanics was developed as a response to the inadequacy of classical physics in explaining certain physical phenomena. While it has proved immensely successful, it also presents several features that severely ...
