Decolourization of textile wastewater by manganese-aluminium metallic particles
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 ...
Estudio de la inhomogeneidad elástica en vidrios metalicos en la mesoescala
Metallic glasses are amorphous solids produced by rapid cooling, with disordered atomic structure and lacking long-range order. This structural disorder makes them to show mechanical properties different from those observed ...
Optimal trajectory management for aircraft descent operations subject to time constraints
The growth in traffic increased the pressure on the environmental sustainability of air transport. In this context, many research effort has been devoted to minimise the environmental impact in the different phases of ...
Global ionospheric maps : estimation and assessment in post-processing and real-time
The research of this paper-based dissertation is focused on Global Ionospheric Maps (GIM) generation and assessment. In summary, the novelty and thematic unity in this works relies on four different but complementary topics: ...
Hilbert analysis of air temperature dynamics
The dynamics of the climate system plays a crucial role in the sustainability of life on Earth, and this motivates research to understand and characterise our climate and predict its evolution. In this thesis we focus on ...
Data-driven neural mass modelling
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 ...
World-wide analysis and modelling of the ionospheric and plasmaspheric electron contents by means of radio occultations
The research of this dissertation is studying the ionosphere by GPS radio occultation (RO) techniques. It is mainly divided into two parts. The first part focuses on the methodology in electron density profile retrievals ...
Cost-based linear holding practice and collaborative air traffic flow management under trajectory based operations
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 ...
Study of the meteorological mechanisms controlling levels and transport processes of airborne pollen in the atmosphere
Aerobiology is the science that focuses on the study of the airborne living organisms (bacteria, fungal spores, pollen, small insects, etc.). The influence of meteorology and climate change on plant phenology include shifts ...
Dynamics and physical processes involving extreme temperatures in the Iberian Peninsula and Iraq
The occurrence of heat waves and cold spells has received special attention in recent years due to their impact on human health, ecosystems and economy. In the context of climate change, there is evidence that extreme ...
Historical review of fire safety at NPP and application of fire PSA to Westinghouse PWR NPP in the frame of risk-informed decision making by
The importance of fire as a potential initiator of multiple-system failures took on a new perspective after the cable-tray fire at Browns Ferry in 1975 The review have shown that the first generation Nuclear Power Plant ...
A high-performace computing tool for partitioned multi-physics applications
The simulation and modelling of complex applications involving the interaction of processes governed by different physical principles is addressed in this thesis. The interaction of a fluid with a deformable body, or the ...
Relaxation dynamics and crystallization kinetics of glass-forming drugs
Glassy phases play an important role in our daily life and in many industries such as the food, pharmaceutical, and construction and are responsible for certain vital mechanisms in living species. Whereas crystals are solid ...
Dynamics of cyclones and precipitation over the Middle East
Precipitation is one of the most important, and also difficult to predict, elements of climate. This difficulty is associated with the transport of moisture through weather fronts that change their pathway, shape and ...
Dynamics of large-scale shoreline perturbations
Shorelines around the world are rarely smooth and they can present undulations and cuspate shapes. On the one hand, human actions can cause shoreline perturbations via beach nourishments, which in turn perturb the wave ...
Light management in non-Hermitian systems
The quest for new artificial structures and materials uncovers novel new light-matter interactions, and intriguing physical phenomena. Since the late 80’s purely dielectric materials have been structured, at the wavelength-scale, ...
Neutronics analysis and thermodynamics studies of several DEMO breeding blankets for the development of the AINA safety code
By 2050 the energy consumption is expected to increase considerably.The production might be mostly based on renewable energy mix driven by the nuclear fusion which could potentially deliver continuous, large-scale power ...
Desarrollo y aplicación de herramientas de valoración de riesgos tecnológicos en centrales nucleares españolas a partir de la técnica de "Análisis Probabilista de Seguridad"
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 ...
Solid-state studies on C60 solvates
This thesis focuses on the thermodynamic and crystallographic characterization of C60 solvates formed with small organic molecules (CBr2(CH3)2, CBr2Cl2, CBr2H2, CBrCl2H and CBrClH2) Chapter I provides an introduction ...
Second harmonic generation in disordered nonlinear crystals : application to ultra-short laser pulse characterization
The PhD project, entitled "Second harmonic generation in disordered nonlinear crystals: application to ultra-short laser pulse characterization", is devoted to the study of second harmonic generation in nonlinear ferroelectric ...
