Validación de Competencias en Titulaciones Universitarias Usando Minería de Datos
(IEEE-RITA Revista Iberoamericana de Tecnologías del aprendizaje, 2010, Vol. 5, No. 1 (Febrer), 2010-02)Nowadays the successful acquisition of competences is the base for the achievement of the professional skills and, consequently, the educational methodologies need to be reconsidered. This work describes ... -
Variation of Ionospheric Narrowband and Wideband Performance for a 12,760 km Transequatorial Link and Its Dependence on Solar and Ionospheric Activity
(Remote Sensing, 2020, Vol.12 no 17, 2020-08)The ionosphere provides a channel that is able to propagate electromagnetic waves for long-haul communications, allowing Non-Line-Of-Sight (NLOS) radio communications in the high-frequency band (HF). ... -
Vertical and oblique ionospheric soundings over a very long multihop HF radio link from polar to midlatitudes: Results and relationships
(Radio Science, 2009. Vol. 44, Rs2014, 2009-04)A vertical incidence sounder (VIS) was installed at the Spanish Antarctic Base (62.7°S, 299.6°E) during the Antarctic summer survey 2004–2005. In addition, an oblique sounding (OS) system for HF ... -
Vertical and Oblique ionospheric soundings over the long haul HF link between Antarctica and Spain
(Radio Science. 2015, Vol. 50, No.9 (Setembre), 2015-09)This paper presents a comparative study between the oblique sounding results, theInternational Telecommunication Union Rec533 HF prediction model, and the vertical sounding results of atransequatorial ... -
Vertical and oblique ionospheric soundings performance comparison over the 12,760 km transequatorial HF link between Antarctica and Spain
(Radio Science. 2017. Vol.52, No.4 (Abril), 2017-03)This paper presents the second part of the study of the oblique sounding of a 12,760 km transequatorial ionospheric link between Livingston Island (Antarctica) and Cambrils in Spain. The study consists ... -
Vertical Extension and Improving of Existing Buildings
(The Open Construction and Building Technology Journal, 2017, 11, (Suppl-1, M4), 2016-11)Low-density urban models, widely diffused in Spain until 2008, have been strongly criticized because they produce a great strain on the land, high infrastructure costs, increasing maintenance expenses, ... -
Virtual interactive innovations applied for digital urban transformations: mixed approach
(Future Generation Computer Systems, No. 91 (Febrer 2019), 2019-02-01)The cities in which we live are changing rapidly, presenting the scenery to debate future visions of transformative designs and its impact on the city. In order to take advantage of the changes and ... -
