Oil spill segmentation in SAR images using convolutional neural networks. A comparative analysis with clustering and logistic regression algorithms
(Elsevier Ltd, 2019-11)[Abstract]: Synthetic aperture radar (SAR) images are a valuable source of information for the detection of marine oil spills. For their effective analysis, it is important to have segmentation algorithms that can delimit ... -
On the estimation of stellar parameters with uncertainty prediction from Generative Artificial Neural Networks: application to Gaia RVS simulated spectra
(EDP Sciences, 2016-10)[Abstract]: Aims. We present an innovative artificial neural network (ANN) architecture, called Generative ANN (GANN), that computes the forward model, that is it learns the function that relates the unknown outputs (stellar ... -
Personalized Virtual Reality Environments for Intervention with People with Disability
(MDPI, 2022)[Abstract] Background: Virtual reality (VR) is a technological resource that allows the generation of an environment of great realism while achieving user immersion. The purpose of this project is to use VR as a complementary ... -
Phosphorus-Rich Stars With Unusual Abundances Are Challenging Theoretical Predictions
(Nature Publishing Group, 2020-08-04)[Abstract] Almost all chemical elements have been made by nucleosynthetic reactions in various kind of stars and have been accumulated along our cosmic history. Among those elements, the origin of phosphorus is of extreme ... -
Planetary Nebulae in Gaia EDR3: Central Star Identification, Properties, and Binarity
(EDP Science, 2021)[Abstract] Context. The Gaia Early Data Release 3 (EDR3), published in December 2020, features improved photometry and astrometry compared to that published in the previous DR2 file and includes a substantially larger ... -
QKDNetSim+: Improvement of the quantum network simulator for NS-3
(Elsevier, 2024)[Abstract]: The first Quantum Key Distribution (QKD) networks are currently being deployed, but the implementation cost is still prohibitive for most researchers. As such, there is a need for realistic QKD network simulators. ... -
Safety and Traceability in Patient Healthcare through the Integration of RFID Technology for Intravenous Mixtures in the Prescription-Validation-Elaboration-Dispensation-Administration Circuit to Day Hospital Patients
This work presents the integration of the RFID technology with the aim of ensuring the traceability of patients and minimization of adverse events during the process of prescription-validation-elaboration-dispensation-ad ... -
Solid confirmation of the broad DIB around 864.8nm using stacked Gaia–RVS spectra
(EDP Sciences, 2022)[Abstract]: Context. Studies of the correlation between different diffuse interstellar bands (DIBs) are important for exploring their origins. However, the Gaia–RVS spectral window between 846 and 870 nm contains few DIBs, ... -
Stellar ages, masses, extinctions, and orbital parameters based on spectroscopic parameters of Gaia DR3
(EDP Sciences, 2023)[Abstract]: Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these ... -
The cerium content of the Milky Way as revealed by Gaia DR3 GSP-Spec abundances
(EDP Sciences, 2023)[Abstract]: The recent Gaia third data release contains a homogeneous analysis of millions of high-quality Radial Velocity Spectrometer (RVS) stellar spectra by the GSP-Spec module. This led to the estimation of millions ... -
The Development of an RFID Solution to Facilitate the Traceability of Patient and Pharmaceutical Data
(M D P I AG, 2017-09-29)[Abstract] One of the principal objectives of hospitals is to increase the quality of care of the patient. This is even more of a priority in Day Hospitals where certain medication requires special attention, from its ... -
The Gaia mission
(EDP Sciences, 2016-11)[Abstract]: Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was ... -
Traceability in Patient Healthcare through the Integration of RFID Technology in an ICU in a Hospital
(M D P I AG, 2018-05-19)[Abstract] Patient safety is a principal concern for health professionals in the care process and it is, therefore, necessary to provide information management systems to each unit of the hospital, capable of tracking ...
