Modified oriented dihedral model for scattering characteristic description with PolSAR data
(Institute of Electrical and Electronics Engineers (IEEE), 2024-01-19)
Article
Accés obertDihedral is a common structure in polarimetric SAR images and can be found on many man-made targets. Many researchers have proposed different dihedral models, but the accuracy of these models is limited. In this case, the ... -
The role of network digital twinning in a 6G-oriented optimization-as-a-service platform
(Luis Landesa-Porras, 2023)
Comunicació de congrés
Accés obertThe advent of 5G has meant providing users with higher data rates, more connected devices and lower latency, implying the need to redefine traditional network management methods. In addition, 6G is expected to provide much ... -
Simple randomized strategies for low-rank matrix compression
(Universidad de Sevilla, 2023)
Text en actes de congrés
Accés obertWe propose a randomized Pseudo Skeleton (or CUR) approximation method to compress the H-matrices of linear systems that arise in the discretization of integral equations in electromagnetic scattering. This method is ... -
Improvements in randomized matrix compression methods for numerical analysis of antennas and scatterers
(Luis Landesa-Porras, 2023)
Comunicació de congrés
Accés obertWe propose a randomized Pseudo Skeleton (or CUR) Approximation method to compress the H-matrices of linear systems that arise in the discretization of integral equations in electromagnetic scattering. This method is highly ... -
On the design of a network digital twin for the radio access network in 5G and beyond
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-01-20)
Article
Accés obertA Network Digital Twin (NDT) is a high-fidelity digital mirror of a real network. Given the increasing complexity of 5G and beyond networks, the use of an NDT becomes useful as a platform for testing configurations and ... -
IA generativa i ChatGPT. Impacte en l’aprenentatge universitari
(2024)
Report de recerca
Accés obertEs presenten de forma planera els elements bàsics de la intel·ligència artificial (IA) generativa. Sobretot es descriuen els models de llenguatge de gran capacitat, que són la base d’eines com el xatbot ChatGPT. A continuació ... -
An assessment of SAOCOM L-Band PolInSAR capabilities for canopy height estimation: A case study over managed forests in Argentina
(Institute of Electrical and Electronics Engineers (IEEE), 2024-02-07)
Article
Accés obertThis work presents the first results of canopy height mapping with L -Band SAOCOM data by means of Polarimetric SAR Interferometry (PolInSAR). For this study case, a colocated temporal series of SAOCOM fully polarimetric ... -
Wavefront-modified vector beams for THz cornea spectroscopy
(Optical Society of American (OSA), 2023-11-20)
Article
Accés obertTerahertz spectroscopy is a promising method to diagnose ocular diseases, where the cornea is typically imaged by Gaussian beams. However, the beam’s mismatch with the cornea’s spherical surface produces a 5-10 % error in ... -
Curved boundary integral method for electromagnetic fields
(Optical Society of American (OSA), 2023-12-11)
Article
Accés obertThe angular spectrum method is a rigorous method to synthesize near and far-field electromagnetic beams from planar field distributions. However, this limitation of planar surfaces has restricted its applicability to beams ... -
Quality control of Doppler spectra from a vertically pointing, S-band profiling radar
(American Meteorological Society, 2024-02-21)
Article
Accés restringit per política de l'editorialThis study describes a novel combination of methods to remove spurious spectral peaks, or “spurs,” from Doppler spectra produced by a vertically pointing, S-band radar. The University of Massachusetts S-band frequency-modulated, ... -
Land, jet stream, and other atmospheric effects on burned area estimation during the South Asian heatwave of 2022
(2024-04)
Article
Accés obertUnderstanding the key variables that characterise fire propagation is important for a better estimation of fire events and their impacts. This study uses machine learning combined with satellite remote sensing and atmospheric ... -
Correlation study between the performance in different engineering courses and project-based courses
(NTNU SEED, 2023)
Comunicació de congrés
Accés obertIn a previous study, already published (Bragós, 2022), we analyzed the correlation between the University access mark to the engineering studies with the grades obtained in projectbased courses and in non-project-based ...
