Assessment of a TEC calibration procedure by single-frequency PPP
(2018-04-01)
Global navigation satellite system (GNSS) measurements have become an outstanding data source for ionospheric studies using total electron content (TEC) estimation procedures. Many methods for TEC estimation had been ...
Temporal and spatial variability of the bias between TOPEX- and GPS-derived total electron content
(Springer, 2005-06)
Total Electron Content (TEC) predictions made with the GPS-based La Plata Ionospheric Model (LPIM) and the International Reference Ionosphere (IRI95) model were compared to estimates from the dual-frequency altimeter onboard ...

Incidencia de infección y trombosis asociadas al catéter central de inserción periférica (PICC) implantados por el servicio de radiología intervencionista de los Hospitales Tec Salud
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2018-07-23)
Objetivo general: Determinar la incidencia de trombosis venosa (TV) e infección asociada al catéter central de inserción periférica (PICCs).Métodos y materiales: Se realizó un estudio retrospectivo, replicativo y descriptivo ...
Improvement of retrieved FORMOSAT‐3/COSMIC electron densities validated by ionospheric sounder measurements at Jicamarca
(American Geophysical Union, 2011-09-01)
Inversion techniques applied to GPS‐LEO radio occultation data allow the retrieval of accurate and worldwide‐distributed refractivity profiles, which, in the case of the ionosphere, can be converted into electron densities ...
