Evaluation of the surface impedance of ReBCO coated conductors and requirements for their use as beam screen materials for the FCC-hh
(Universitat Politècnica de Catalunya, 2022-11-25)
Doctoral thesis
Open Access(English) The Future Circular Hadron Collider (FCC-hh) is a proposal for a 100-kilometre-long particle accelerator with collision energy substantially higher than previous colliders to expand the Large Hadron Collider (LHC) ... -
Gender bias in natural language processing
(Universitat Politècnica de Catalunya, 2022-10-14)
Doctoral thesis
Open Access(English) Gender bias is a dangerous form of social bias impacting an essential group of people. The effect of gender bias is propagated to our data, causing the accuracy of the predictions in models to be different depending ... -
Advanced methods for earth observation data synergy for geophysical parameter retrieval
(Universitat Politècnica de Catalunya, 2022-07-15)
Doctoral thesis
Open AccessThe first part of the thesis focuses on the analysis of relevant factors to estimate the response time between satellite-based and in-situ soil moisture (SM) using a Dynamic Time Warping (DTW). DTW was applied to the SMOS ... -
Synergistic optical and microwave remote sensing approaches for soil moisture mapping at high resolution
(Universitat Politècnica de Catalunya, 2022-05-27)
Doctoral thesis
Open AccessSoil moisture is an essential climate variable that plays a crucial role linking the Earth’s water, energy, and carbon cycles. It is responsible for the water exchange between the Earth’s surface and the atmosphere, and ... -
Deriving vertical total electron content maps from SMOS full polarimetric data to compensate the Faraday rotation effect
(Universitat Politècnica de Catalunya, 2022-09-16)
Doctoral thesis
Open AccessThe Faraday rotation is a geophysical effect that causes a rotation of the electromagnetic field components emitted by the Earth when it propagates through the ionosphere. It depends on the vertical total electron content ... -
