Optimal trajectory management for aircraft descent operations subject to time constraints
(Universitat Politècnica de Catalunya, 2019-06-25)
Doctoral thesis
Open AccessThe 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 ... -
Estudio de la inhomogeneidad elástica en vidrios metalicos en la mesoescala
(Universitat Politècnica de Catalunya, 2019-06-28)
Doctoral thesis
Open AccessMetallic 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 ... -
Hilbert analysis of air temperature dynamics
(Universitat Politècnica de Catalunya, 2019-04-04)
Doctoral thesis
Open AccessThe 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 ... -
Global ionospheric maps : estimation and assessment in post-processing and real-time
(Universitat Politècnica de Catalunya, 2019-04-09)
Doctoral thesis
Open AccessThe 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: ... -
Data-driven neural mass modelling
(Universitat Politècnica de Catalunya, 2019-03-28)
Doctoral thesis
Open AccessThe 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
(Universitat Politècnica de Catalunya, 2019-02-25)
Doctoral thesis
Open AccessThe 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
(Universitat Politècnica de Catalunya, 2018-11-20)
Doctoral thesis
Open AccessThe 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 ... -
Dynamics and physical processes involving extreme temperatures in the Iberian Peninsula and Iraq
(Universitat Politècnica de Catalunya, 2018-10-03)
Doctoral thesis
Open AccessThe 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 ... -
Study of the meteorological mechanisms controlling levels and transport processes of airborne pollen in the atmosphere
(Universitat Politècnica de Catalunya, 2018-10-05)
Doctoral thesis
Open AccessAerobiology 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 ... -
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
(Universitat Politècnica de Catalunya, 2018-10-05)
Doctoral thesis
Open AccessThe 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 ... -
Relaxation dynamics and crystallization kinetics of glass-forming drugs
(Universitat Politècnica de Catalunya, 2018-09-14)
Doctoral thesis
Open AccessGlassy 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
(Universitat Politècnica de Catalunya, 2018-09-25)
Doctoral thesis
Open AccessPrecipitation 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 ...
