Gaia Data Release 2: Observational Hertzsprung-Russell diagrams
(EDP Sciences, 2018)
[Abstract] Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and homogeneity of both astrometry and photometry ...
Gaia Data Release 2: Mapping the Milky Way disc kinematics
(EDP Sciences, 2018)
[Abstract] Context. The second Gaia data release (Gaia DR2) contains high-precision positions, parallaxes, and proper motions for 1.3 billion sources as well as line-of-sight velocities for 7.2 million stars brighter than ...
La estructura espacial de Galicia. Análisis a partir del cálculo de los potenciales de mercado a nivel comarcal, 1991-2016
(Facultade de Ciencias Económicas e Empresariais, Universidade de Santiago de Compostela, 2018)
[Resumen]: En este artículo se analiza la distribución espacial de la actividad económica en las comarcas de
Galicia a través del cálculo del potencial de mercado de Harris (1954) y los índices de Gini y
curvas de Lorenz ...
El estudio de los buques de superficie autónomos, inteligentes y sostenibles: la extinción de las tripulaciones de los buques
(Universidad Nacional de La Matanza, 2019-05)
[Resumen]:Desde hace no muchos años, de forma paralela a su aparición en la telefonía móvil, o en automoción, se presentan ante nosotros los denominados buques autónomos o inteligentes. Por ello en 2018 tuvo lugar la primera ...
Gaia Data Release 2: Observations of solar system objects
(EDP Sciences, 2018)
[Abstract] Context. The Gaia spacecraft of the European Space Agency (ESA) has been securing observations of solar system objects (SSOs) since the beginning of its operations. Data Release 2 (DR2) contains the observations ...
La aldea como ‘espacio hídrico”
(Universidad de Zaragoza, 2018)
[Resumen]
En los territorios de los valles altos de Galicia, las aldeas responden al secular conocimiento y manejo de la escorrentía del agua. Se emplazan a media ladera, entre el monte -donde las brañas, “chaos” y ...
Gaia Data Release 2: Summary of the contents and survey properties
(EDP Sciences, 2018-08)
[Abstract]: Context. We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources brighter than magnitude ...
Gaia Data Release 1: Summary of the astrometric, photometric, and survey properties
(EDP Sciences, 2016-11)
[Abstract]: Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A ...
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 ...
Network Data Flow Clustering based on Unsupervised Learning
(Institute of Electrical and Electronics Engineers Inc., 2019)
[Abstract]: Network communication data analysis is crucial in order to provide an adequate security level in computer infrastructures. As the volume of data and the number of features rise, the difficulties associated with ...
