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 ...
Mining of the Milky Way Star Archive Gaia-DR2: Searching for Binary Stars in Planetary Nebulae
(MDPI AG, 2020-08-31)
[Abstract]
The aim of this work is to search for binary stars associated to planetary nebulae (ionized stellar envelopes in expansion), by mining the astronomical archive of Gaia DR2, that is composed by around 1.7 billion ...
Distributed Fast Self-Organized Maps for Massive Spectrophotometric Data Analysis
(MDPI AG, 2018-05-03)
[Abstract] Analyzing huge amounts of data becomes essential in the era of Big Data, where databases are populated with hundreds of Gigabytes that must be processed to extract knowledge. Hence, classical algorithms must be ...
Analyzing Supervised Machine Learning Models for Classifying Astronomical Objects Using Gaia DR3 Spectral Features
(MDPI, 2024)
[Abstract] In this paper, we present an analysis of the effectiveness of various machine learning algorithms in classifying astronomical objects using data from the third release (DR3) of the Gaia space mission. The dataset ...
Tracking and Minimization of Adverse Events in the Patient Care Process while in a Hospital Emergency Service Area
(M D P I AG, 2019-11-20)
[Abstract] The aim of this work was to integrate and computerize into a single program the most important tasks in the process of prescription, dispensation, and administration of medication to patients during their stay ...
A privacy-preserving key transmission protocol to distribute QRNG keys using zk-SNARKs
(Elsevier B.V., 2024-04)
[Absctract]: High-entropy random numbers are an essential part of cryptography, and Quantum Random Number Generators (QRNG) are an emergent technology that can provide high-quality keys for cryptographic algorithms but ...
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 ...
Gaia Early Data Release 3: Acceleration of the Solar System from Gaia Astrometry
(EDP Sciences, 2021)
[Abstract] Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quality five-parameter astrometric ...
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 ...
