(English) Snapshot positioning is the technique to determine the position of a Global Navigation Satellite System (GNSS) receiver using only a very brief interval of the received satellite signal. In recent years, this ...
This dissertation focuses on determining the vertical electron content distribution in low and high vertical resolution from ground-based and LEO on board GNSS data and improving the knowledge of ionosphere climatology in ...
(English) Global Navigation Satellite System (GNSS) have revolutionized location and timing technologies due to their low cost and wide availability. Initially, GNSS was limited to the american Global Positioning System ...
(English) This document presents the collection of four manuscripts published during my Doctoral academic formation, which main goal has been the real-time implementation of tools to monitor the ionosphere using Global ...
The main goal of this thesis is the computation of ground state properties of quantum many-body systems under Spin Orbit coupling (SOC) interactions out of the ultradilute regime. We present two approaches to fulfill this ...
Cu-based alloys are widely applied in corrosive environments. The improvement of the alloys' corrosion resistance will significantly reduce energy consumption and overexploitation of resources. To increase the resistance ...
The current air transportation system is reaching the capacity limit in many countries/regions across the world. It tends to be less efficient or even incapable sometimes to deal with the enormous air traffic demand that ...
(English) Unmanned aerial vehicles (UAV) also known as drones have been used for a variety of reasons such as surveillance, reconnaissance, shipping and delivery, etc. and commercial drone market growth is expected to reach ...
The brain is known to operate under the constant influence of noise arising from a variety of sources. It also organises its activity into rhythms spanning multiple frequency bands. These rhythms originate from neuronal ...
(English) Fiber-reinforced polymers (FRPs) are the most used composite materials in many applications, from broom handle to the main structure of advanced aircraft. Despite the enormous research done on these materials, ...
The brain is a complex organ whose activity spans multiple scales, both spatial and temporal. The computational unit of the brain is thought to be the neurone. At the microscopic level, neurones communicate via action ...
Waste treatment is an important aspect of an industry. Organic dyes are used in many fields, such as textile, paper or food. Residual dye compounds from these industries are one of the most critical sources of environmental ...
(English) Nowadays Air Navigation Service Providers (ANSPs) have to handle and accommodate a continuously increasing traffic demand in a scenario that is expected to be more time-efficient and cost-efficient. Meeting the ...
The PhD thesis "Desarrollo y aplicación de herramientas de valoración de riesgos tecnológicos en centrales nucleares españolas a partir de la técnica de Análisis Probabilista de Seguridad” results from the research projects ...
The main objective of this work is to design the BEta-deLayEd Neutron detector (BELEN) detector for FAIR (Facility for Antiproton Ion Research). The purpose of this detector is the measurement of neutron emission probabilities ...
A variety of morphodynamic patterns are typically present in the nearshore zone of sandy beaches that develop due to the interactions between waves, currents and the morphology. The most common are one or several nearshore ...
In Synchrotron Light Source facilities with high energy and low emittance electron beams different techniques for improving the quality of the synchrotron light for the users are applied. With this aim ALBA, the Spanish ...
Magnetic fusion is a long term, worldwide research activity. Plans are increasingly ambitious, cooperation is progressing, and goals seem to be closer every year. ITER reactor is being built, and several conceptual studies ...
A conclusion that can be drawn from the historical safety analyses developed for tokamaks fusion reactors is that some of the major risks involve incidents in the vacuum vessel. In order to evaluate plasma evolution and ...
In this thesis we employ dielectric spectroscopy (in different implementations) to study the dielectric properties of different materials ranging from completely disordered supercooled liquids to low-disorder solids with ...
