Gaia Early Data Release 3: Summary of the Contents and Survey Properties
(EDP Sciences, 2021)
[Abstract] Context. We present the early installment of the third Gaia data release, Gaia EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter than magnitude 21, complemented with the list of ...
Gaia DR2 Distances to Planetary Nebulae
(MDPI AG, 2020-04-01)
[Abstract] The aim of this work is to examine distances to planetary nebulae (PNe) together with other properties that were derived from them, using the astrometry of Gaia Data Release 2 (DR2). We were able to identify ...
A First Approach to Authentication Based on Artificial Intelligence for Touch-Screen Devices
(MDPI AG, 2020-08-18)
[Abstract]
Most authentication schemes follow a classical approach, where the users are authenticated only once at the beginning of their sessions. Therefore, it is not possible to verify the legitimate use of such a ...
Open Source Monitoring System for IT Infrastructures Incorporating IoT-Based Sensors
(MDPI AG, 2020-09-03)
[Abstract]
This paper introduces the development of a data center monitoring system based on IoT technologies. The system is meant to work as an administrative tool for system administrators in any environment, but mainly ...
Close Binary Stars in Planetary Nebulae through Gaia EDR3
(MDPI, 2021)
[Abstract] The aim of this work is to search for evidence of close binary stars associated with planetary nebulae (ionized stellar envelopes in expansion) by mining the astronomical archive of Gaia EDR3. For this task, ...
Signal Processing Techniques Intended for Peculiar Star Detection in APOGEE Survey
(M D P I AG, 2019-08-01)
[Abstract] Like other disciplines, Astronomy faces the era of Big Data, where the analyses and discovery of specific objects is a significant and non-trivial matter. The APOGEE survey and Gaia mission are good examples of ...
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 ...
Gaia Early Data Release 3: The Galactic Anticentre
(EDP Sciences, 2021)
[Abstract] Aims. We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of different aspects of the Milky Way structure and evolution and we provide, at the same time, a ...
A Blended Artificial Intelligence Approach for Spectral Classification of Stars in Massive Astronomical Surveys
(MDPI AG, 2020-05-01)
[Abstract]
This paper analyzes and compares the sensitivity and suitability of several artificial intelligence techniques applied to the Morgan–Keenan (MK) system for the classification of stars. The MK system is based ...
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 ...
