Life Settlements y Viaticals
Esta tesis doctoral se enmarca en un novedoso mercado basado en la compra/venta de pólizas de vida donde se comercializan dos tipos de productos: el Viatical y el Settlement. Un primer análisis se centra en el desarrollo ...
Life-history, ecology and fisheries of cephalopods in the western Mediterranean
Cephalopods constitute an important faunistic group in marine ecosystems, representing keystone elements in marine food webs. Additionally, they are an important fishing resource, and their contribution to worldwide fishery ...
Lifelike Humans: Detailed Reconstruction of Expressive Human Faces
El desenvolupament de personatges digitals semblants a les persones és una tasca difícil, ja que els humans estem acostumats a reconèixer-nos entre nosaltres i trobar els CGI poc humanitzats. Per complir els estàndards ...
Lifelong AI-driven zero-touch network slicing
(English) The sixth-generation (6G) network's evolution necessitates advancements in algorithms and architecture to transition from an AI-native to an intrinsic trustworthy automation-native system. Network slicing creates ...
Lifelong Learning of Neural Networks: Detecting Novelty and Adapting to New Domains without Forgetting
La visió per computador ha experimentat canvis considerables en l’última dècada, ja que les xarxes neuronals han passat a ser d’ús comú. A mesura que les capacitats computacionals disponibles han crescut, les xarxes neuronals ...
Lifestyle interventions and cognitive change: determinants and underlying mechanisms
Les intervencions que milloren l’estil de vida (dieta, exercici físic i entrenament cognitiu) poden frenar el declivi cognitiu en persones a risc de demència. En el context d’intervencions en l’estil de vida, aquesta ...
Lifestyle Understanding through the Analysis of Egocentric Photo-streams
Describing people’s lives has become a hot topic in several disciplines. Lifelogging appeared in the 1960s as the process of recording and tracking personal activity data generated by the daily behaviour of a person. The ...
Ligand design for palladium and iridium selective catalysts
This doctoral thesis focuses on the synthesis of new ligands and their application in two types of catalytic process: a) palladium catalysed carbonylation reactions and b) asymmetric reactions (hydrogenation of challenge ...
Ligand selectivity at GPCRs: from multitarget binding profiles to biased agonism
La caracterització de diversos fàrmacs capaços d’unir-se a receptors associats a proteïnes G (GPCR)s ha revelat que els seus mecanismes d’acció no eren tan simples com es creia. Primer, l’anàlisi de la seva afinitat d’unió ...
Ligandos Supramoleculares en Complejos Metálicos con Propiedades Físicas Relevantes
En la primera parte de esta tesis, se basó en la síntesis de ligandos basados en la heptazina y los complejos formados con CuII. Utilizando 2-dipiridilamina para funcionalizar el núcleo de heptazina, (ligando que presenta ...
Light absorption and ergodicity in systems that transform light into other forms of energy
(English) To mitigate the present environmental crisis, caused by the excessive use of fossil fuels and associated release of carbon dioxide into the atmosphere, it is necessary to significantly reduce worldwide energy ...
Light activated gas nanosensors
Aquesta tesi està centrada en explorar la utilitat de la llum ultraviolada per tal d'activar els sensors de gasos basats òxids metàl·lics (MOX), i comparar els resultats amb l'activació per temperatura. Mitjançant l'aplicació ...
Light and taste : third plane side‐view combined with complex fenestration system atmospheres under midday clear sky at restaurants
This thesis deals with sunny side-lit indoor atmospheres, in which an outdoor view is required and a calm environment to enhance concentration. Different window systems were compared: a single fully glazed façade and complex ...
Light beam propagation in complex crystals
Recent advancement in Photonics have brought about a new era of miniaturisation. Along came a need for technology to allow the manipulation of light at the micrometer scale, with precise control over beam propagation. The ...
Light enhancements in nano-structured solar cells
In this century some of our main issues are energy shortage and pollution. This work will briefly describe these problems, proposing a plan of action combining energy saving and different sustainable energy sources. Within ...
Light generation and manipulation from nonlinear randomly distributed domains in SBN
Disordered media with refractive index variations can be found in the atmosphere, the ocean, and in many materials or biological tissues. Several technologies that make use of such random media, as image formation, satellite ...
Light harvesting and energy efficiency in perovskite solar cells and their applications
The environmental issues associated with the use of conventional fuels necessitates the utilisation of renewable energy sources, as well as the implementation of energy efficient designs, in order to decrease electricity ...
Light harvesting in fiber array organic solar cells
