Evaluation of a Tracking System for Patients and Mixed Intravenous Medication Based on RFID Technology
(Multidisciplinary Digital Publishing Institute, 2016)At present, one of the primary concerns of healthcare professionals is how to increase the safety and quality of the care that patients receive during their stay in hospital. This is particularly important in the administration ... -
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 ... -
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 ... -
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: 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 ... -
Gaia Data Release 2: Summary of the contents and survey properties
