(Multidisciplinary Digital Publishing Institute (MDPI), 2025-04-17)
Article
Open AccessThis research aims to estimate long-term aerosol radiative effects by combining radiation and Aerosol Optical Depth (AOD) observations in Barcelona, Spain. Aerosol Radiative Forcing and Aerosol Forcing Efficiency (ARF and ... -
Deep learning-based UWB-IMU data fusion for indoor positioning in industrial scenario
(2025-05-05)
Article
Open AccessAccurate and precise wireless infrastructure-based positioning systems become crucial as industries move towards flexible, portable, and autonomous transportation systems such as Automated Guided Vehicles (AGVs). ... -
A novel geometry agnostic delay and Doppler tracking technique for GNSS-reflectometry: application to the GNOS-II payload onboard the FY-3E
(Institute of Electrical and Electronics Engineers (IEEE), 2025-03-03)
Article
Open AccessGlobal Navigation Satellite System-Reflectometry (GNSS-R) uses GNSS signals as signals of opportunity as a multistatic radar. Most GNSS-R instruments conduct 1 ms coherent integration, followed by 500 or 1000 incoherent ... -
Study of optical scattering properties and direct radiative effects of high-altitude cirrus clouds in Barcelona, Spain, with 4 years of lidar measurements
(European Geosciences Union (EGU), 2025-03-24)
Article
Open AccessCloud–radiation interaction still drives large uncertainties in climate models, and its estimation is key to make more accurate predictions. In this context, high-altitude cirrus clouds play a fundamental role because (1) ... -
Joint class and domain continual learning for decentralized federated processes
(Institute of Electrical and Electronics Engineers (IEEE), 2025-03-28)
Article
Open AccessContinual learning (CL) is attracting attention to learn in dynamic and non-stationary environments, typical of many real applications, such as those related to Internet of things (IoT). So far, learning in IoT scenarios ... -
Accelerated algorithm for back-projection fully focused SAR altimetry
(Institute of Electrical and Electronics Engineers (IEEE), 2025-03-31)
Article
Open AccessFully focused synthetic aperture radar (SAR) back-projection algorithms for radar altimetry have gained attention in the altimetry community due to their improved azimuth resolution compared to traditional methods, such ... -
Global correlation of Swarm satellites magnetic field and TEC data with M4+ earthquakes between 2014 and 2024
(2025-03)
Article
Open AccessBetween 50 and 80 earthquakes are recorded daily, resulting in over 20,000 yearly seismic events. Currently, no reliable earthquake precursors can provide an early warning. Still, research has inspected anomalies in the ... -
Analog radio-over-fiber transmitter with optical frequency upconversion and optimized optical carrier-to-signal ratio
(2025-01-01)
Article
Restricted access - publisher's policyThe performance of an analog radio-over-fiber (A-RoF) transmitter with optical frequency conversion (OFC) is evaluated analytically and experimentally. It employs two push-pull Mach-Zehnder modulators (PP-MZM): one for ... -
A Cartesian encoding graph neural network for crystal structure property prediction: application to thermal ellipsoid estimation
(2025)
Article
Open AccessIn the diffraction resolution of crystal structures, thermal ellipsoids are a critical parameter that is usually more difficult to determine than atomic positions. These ellipsoids are quantified through Anisotropic ... -
Singular detection in noncoherent communications
(2025-04)
Article
Open AccessThis paper proposes a general analysis of codeword detection in noncoherent communications. Motivated by the existence of error floors in various regimes, fundamental characteristics of signal design are investigated. In ... -
Conditional dependence via U-Statistics pruning
(2025-02-06)
Article
Open AccessThe problem of measuring conditional dependence between two random phenomena arises when a third one (a confounder) has a potential influence on the amount of information between them. A typical issue in this challenging ...
