Les imatges de teledetecció de la superfície oceànica proporcionen una vista sinòptica de la complexa geometria de la circulació oceànica, dominada per la variabilitat de mesoescala. Estructures com filaments i vòrtex són ...
There has been an exponential surge of text data in the recent years. As a consequence, unsupervised methods that make use of this data have been steadily growing in the field of natural language processing (NLP). Word ...
El concepto de redes sociales de comunicación rural, como una estructura relacional hecha por nodos que están vinculados por medio de actores tales como pequeños productores rurales, proyectos de desarrollo rural, ...
Sponge assemblages dominate several distinctive, hard-bottom environments, being one of the most important structural organisms at several locations around the world. Although the Mediterranean sponge fauna is among the ...
The ongoing processes of globalization and deregulation are changing the competitive framework in the majority of economic sectors. The appearance of new competitors and technologies entails a sharp increase in competition ...
(English) Cryptography is the science that studies how to achieve secure communication between multiple parties. Under the assumption that any message transmitted is to be ultimately intercepted, the endeavors of cryptography ...
Multithreaded processors are now common in the industry as they offer high performance at a low cost. Traditionally, in such processors, the assignation of hardware resources between the multiple threads is done implicitly, ...
Plasmons are charge oscillations coupled to electromagnetic radiation. One of their most intriguing properties is their deep subwavelength confinement resulting in strongly enhanced light-matter interaction. Metal plasmons ...
The present Thesis is devoted to the study of the physical-chemical properties of selected small-molecules (such as amino-acids like tryptophan or hormones like melatonin) and proteins (such as KRAS-4B) absorbed in model ...
Transition metal dichalcogenides (TMDs) are semiconducting layered materials that can be isolated up to the limit of a single atomic layer. Next to graphene, they are some of the most intensively studied materials within ...
Entanglement and non-local correlations give rise to unprecedented phenomena with no classical analogue. As a result, they have settled themselves as fundamental properties in the study of quantum many-body systems, as ...
(English) Quantum memories are devices that are able to store photonic quantum states and entanglement. Future quantum networks, which could enhance cybersecurity through quantum key distribution, improve the precision in ...
Nowadays, the widespread utilization of intelligent mobile and located-embedded services extends the border of social network sites (SNS) to physical-spatial space. The appearance of SNS changes our daily life meanwhile ...
The term Underused Urban Spaces (UUS) refers to spaces within urban areas that have become unused, or that are being used to a lesser degree than they could or should be. The emergence of such spaces has therefore encouraged ...
Recent technological advances have radically changed the way we communicate. Today’s communication has become ubiquitous and it has fostered the need for information that is easier to create, spread and consume. As a ...
Nano-optics studies the behaviour of light on the nanoscale. In particular, it probes the interaction of light with objects, often of nanometre-size, and reveals fine details of the material's optical properties. Optoelectronics ...
Free-space optical (FSO) communications is drawing increasing attention as a promising technology to overcome bandwidth shortage, of an evermore crowded wireless marketplace. Currently radio-frequency (RF) technology ...
Ara que es comença a treure l’entrellat -o si més no a tenir una nova perspectiva- de la diversitat de microorganismes present als oceans gràcies a la biologia molecular i a la metagenòmica, el següent pas és esbrinar ...
Assembling original documents, historical material, completed or unrealized projects and the evolution of governmental and professional structures, this dissertation explores the development and construction of urban ...
This thesis proposes a new numerical technique: the eXtended Hybridizable Discontinuous Galerkin (X-HDG) Method, to efficiently solve problems including moving boundaries and interfaces. It aims to outperform available ...
