Global Navigation Satellite Systems (GNSS) signals are broadly used for positioning, navigation and timing (PNT) in many different applications and use cases, Athough different PNT technologies are available, GNSS is ...
The research of this paper-based dissertation is focused on the Global Ionospheric Maps (GIMs) based on Global Navigation Satellite System (GNSS) including real-time combination, validation, time resolution and applications. ...
This work evaluates the potential use of signals from the Global Navigation Satellite Systems (GNSS) that scatter off the Earth surface for the retrieval of geophysical information from the cryosphere. For this purpose, ...
Latin America is a heterogeneous region, both geographically, demographically and economically. Specifically from an economic perspectiva, the World Bank classifies some countries in the region as high-income according to ...
Las teorías surgidas en el paso del siglo XIX al XX seguramente fueron las responsables de los cambios y de la manera de plasmar la ciudad en esa época. Nuestra atención se centra en el estudio de la forma de interacción ...
Goniochromatic pigments, such as automotive coatings, are known by their appearance changes - especially of colour and visual texture - as a function of the angles of illumination and observation; they are classified as ...
Formulación matemática de un método general para el diseño de redes y su aplicación para resolver problemas de optimización en algunas familias de redes conocidas así como para nuevas familias definidas.
Los estudios desarrollados se enmarcan, dentro de la teoría de grafos, en el análisis de condiciones suficientes para obtener algunas medidas de conectividad optima.se han estudiado condiciones de tipo mixto para el caso ...
In the packaging industry, a wide range of powders and bulk solids are handled in bagging equipment using different bulk feeding techniques. Quality of the packaging is critically affected by feeder performance, which is ...
(English) Deep Learning allows the extraction of complex features directly from raw input data, eliminating the need for hand-crafted features from the classical Machine Learning pipeline. This new paradigm brought a boost ...
Over the last decade, we have witnessed the emergence of networks in a wide spectrum of application domains, ranging from social and information networks to biological and transportation networks. Graphs provide a solid ...
In this thesis we use analytic combinatorics to deal with two related problems: graph enumeration and random graphs from constrained classes of graphs. We are interested in drawing a general picture of some graph families ...
Aquest treball és una contribució a l'estudi de diferents problemes que sorgeixen de dues àrees fortament connexes de la Teoria de Grafs: etiquetaments i descomposicions. Molts etiquetaments de grafs deuen el seu origen ...
The main goal of this thesis is to develop lossless compression schemes for analog and binary sources. All the considered compression schemes have as common feature that the encoder can be represented by a graph, so they ...
This thesis focuses on the phonetic transcription in the framework of text-to-speech conversion, especially on improving adaptability, reliability and multilingual support in the phonetic module. The language is constantly ...
(English) Despite the extensive research in the semiconductor industry, Moore’s law is finally slowing down due to increased complexity. Hence, intense efforts are being carried out to explore hybrid solutions by adding ...
In recent years, mechanical resonators based on graphene have attracted considerable interest as nanoelectromechanical systems (NEMS). Graphene NEMSs allow for exceptional properties such as high mechanical strength, high ...
Since its discovery in 2004, graphene, a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice, has attracted huge interest from the scientific community due to its extraordinary electronic, mechanical, and ...
Several aspects have to be addressed before realizing the dream of a robotic hand-arm system with human-like capabilities, ranging from the consolidation of a proper mechatronic design, to the development of precise, ...
Durant els darrers anys el Grid ha sorgit com una nova plataforma per la computació distribuïda. La tecnologia Gris permet unir diferents recursos de diferents dominis administratius i formar un superordinador virtual amb ...
