Arcos Gutiérrez, David (Date of defense: 2022-07-19)
Two-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, ...
Silini, Riccardo (Date of defense: 2022-07-05)
To 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 ...
Múgica Gallart, Julia (Date of defense: 2023-06-07)
(English) Collective behavior in animals is ubiquitous in nature. It emerges from the self-organization of interacting individuals within a group. What makes collective behavior so interesting is that the behavior of the ...
Pitta, Siddharth (Date of defense: 2020-07-10)
In the modern era of transportation, air travel has gained a huge pace and still kept increasing. The global demand for air transport is increasing at a rate of 6%, because of population growth and ticket price reductions. ...
Gallart Escolà, Dani (Date of defense: 2019-09-27)
Heating plasmas to a relevant fusion temperature is one of the key aspects of magnetically confined fusion plasmas. Radio frequency (RF) heating with electromagnetic waves in the ion cyclotron range of frequencies (ICRF) ...
Moreno Ramos, Eduardo (Date of defense: 2022-05-30)
Cell motility is important in many biological processes. Some examples relay in epidermal cells moving towards lesions during wound healing, neutrophils cells migrating towards sites of bacterial infection as part of the ...
Tahat, Amani Naser (Date of defense: 2016-06-01)
This thesis aims at studying the microscopic physical-chemical properties of an excess proton in aqueous systems. From bulk water environments to narrow hydrophobic channels constructed with a double-layered graphene slab, ...
Rovira Garcia, Adrià (Date of defense: 2016-01-21)
The research of this paper-based dissertation is focused on the Fast Precise Point Positioning (Fast-PPP) technique. The novelty relies on using an accurate ionosphere model, in combination with the standard precise satellite ...
Carreno-Luengo, Hugo (Date of defense: 2016-01-21)
Global Navigation Satellite Systems Reflectometry (GNSS-R) is a multi-static radar using navigation signals as signals of opportunity. It provides wide-swath and improved spatio-temporal sampling over current space-borne ...
Liu, Xiao (Date of defense: 2022-11-10)
(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 ...
Lyu, Haixia (Date of defense: 2020-11-17)
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 ...
Ibáñez Segura, Deimos (Date of defense: 2023-10-23)
(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 ...
Timoté Bejarano, Cristhian Camilo (Date of defense: 2023-03-27)
(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 ...
Sánchez Baena, Juan (Date of defense: 2020-12-14)
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 ...
Xie, Chenyang (Date of defense: 2021-01-08)
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 ...
Xu, Yan (Date of defense: 2018-11-20)
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 ...
Çetin, Ender (Date of defense: 2023-08-30)
(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 ...
Jedynak, Maciej (Date of defense: 2017-03-27)
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 ...
Sabounchi, Saeed (Date of defense: 2023-04-13)
(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, ...
Escuain i Poole, Lara Sofia (Date of defense: 2019-03-28)
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 ...
