Atomistic study of slip transfer in BCC metals
(Universitat Politècnica de Catalunya, 2022-11-16)
Doctoral thesis
Open Access(English) The mechanical properties of structural materials, which are naturally polycrystalline, is defined by a number of physical processes that take place at different time and space scales. On several of those processes, ... -
Contributions to high accuracy snapshot GNSS positioning
(Universitat Politècnica de Catalunya, 2022-11-10)
Doctoral thesis
Open Access(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 ... -
Machine learning for aircraft trajectory prediction: a solution for pre-tactical air traffic flow management
(Universitat Politècnica de Catalunya, 2022-11-08)
Doctoral thesis
Open Access(English) The goal of air traffic flow and capacity management (ATFCM) is to ensure that airport and airspace capacity meet traffic demand while optimising traffic flows to avoid exceeding the available capacity when it ... -
Development and interactions of surfzone morphological patterns
(Universitat Politècnica de Catalunya, 2022-07-19)
Doctoral thesis
Open AccessA 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 ... -
Caracterització optoelectrònica de materials bidimensionals a altes freqüencies
(Universitat Politècnica de Catalunya, 2022-07-19)
Doctoral thesis
Open AccessTwo-dimensional materials have a lot of applications in the electronic and photonic device design field, especially when they need to be flexible and transparent. In particular, high frequency applications, above 100MHz, ... -
Modelling emergent rhythmic activity in the cerebal cortex
(Universitat Politècnica de Catalunya, 2022-10-07)
Doctoral thesis
Open AccessThe brain, a natural adaptive system, can generate a rich dynamic repertoire of spontaneous activity even in the absence of stimulation. The spatiotemporal pattern of this spontaneous activity is determined by the brain ... -
Evaluation of TH multi-scale coupling methods in BEPU analysis
(Universitat Politècnica de Catalunya, 2022-10-11)
Doctoral thesis
Open AccessThe combined use of thermal-hydraulics system with sub-channel codes (TH-TH coupling) in transient analysis provides an integrated tool with the capability of modelling in detail both the core thermal-hydraulic conditions ... -
Sentinel-1 data exploitation for terrain deformation monitoring
(Universitat Politècnica de Catalunya, 2022-09-29)
Doctoral thesis
Open AccessPersistent Scatterer interferometry (PSI) is a group of advanced differential interferometric Synthetic Aperture Radar (SAR) techniques used to measure and monitor terrain deformation. Sentinel-1 has improved the data ... -
Barocaloric effects at first-order phase transitions
(Universitat Politècnica de Catalunya, 2021-04-15)
Doctoral thesis
Open AccessCurrent refrigeration devices, based on vapour-compression cycles, employ refrigerants such as HFCs, which exhibit a global warming potential a thousand times higher than the one produced by CO2,. Furthermore, the increasing ... -
Optimization on industrial problems focussing on multi-player strategies
(Universitat Politècnica de Catalunya, 2022-07-26)
Doctoral thesis
Open AccessAlgorithms (EA) are useful optimization methods for exploration of the search space, but they usually have slowness problems to exploit and converge to the minimum with accuracy. On the other hand, gradient based methods ... -
Causal inference and forescasting methods for climate data nalysis
(Universitat Politècnica de Catalunya, 2022-07-05)
Doctoral thesis
Open AccessTo advance time series forecasting we need to progress on multiple fronts. In this thesis, we develop algorithms to identify causal relations which allow to identify the driving processes containing useful information for ... -
Network-based ionospheric gradient monitoring to support ground based augmentation systems
(Universitat Politècnica de Catalunya, 2022-07-12)
Doctoral thesis
Open AccessThe Ground Based Augmentation System (GBAS) is a local-area, airport-based augmentation of Global Navigation Satellite Systems (GNSSs) that provides precision approach guidance for aircraft. It enhances GNSS performance ...
