GUASOM: An Adaptive Visualization Tool for Unsupervised Clustering in Spectrophotometric Astronomical Surveys
(Springer, 2022)
[Abstract] We present an adaptive visualization tool for unsupervised classification of astronomical objects in a Big Data context such as the one found in the increasingly popular large spectrophotometric sky surveys. ...
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 ...
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 ...
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, ...
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 ...
Low Cost Automated Security Audit System
(MDPI, 2021)
[Abstract] In recent years, a quick transition towards digitization has been observed in most organizations. Along with it, certain inherent problems have appeared, such as the increase in cyber threats. Large organizations ...
Analysis and Knowledge Discovery by Means of Self-Organizing Maps for Gaia Data Releases
(Springer, 2016)
[Abstract]: A billion stars: this is the approximate amount of visible objects estimated to be observed by the Gaia satellite, representing roughly 1 % of the objects in the Galaxy. It constitutes the biggest amount of ...
Distributed Fast Self-Organized Maps for Massive Spectrophotometric Data Analysis
(MDPI, 2018-11)
[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 ...
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. ...
