Interannual Variation of a 12,760 km Transequatorial Ionospheric Channel Availability and Its Dependence on Ionization
(MDPI, 2016-07-15)
The ionosphere provides a channel able for long-haul and Non-Line-Of-Sight (NLOS) communications. Nonetheless, the amount of ionization depends on the Sun activity, whose diurnal and seasonal cycles ...
Narrowband and Wideband Channel Sounding of an Antarctica to Spain Ionospheric Radio Link
(The 1st International Electronic Conference on Remote Sensing, Basel, 22 of June to 5 of July 2015, 2015-06)
La Salle and Ebro Observatory have been involved in several joint projects about
remote sensing in Antarctica for the last 11 years (approximately one solar cycle). The Ebro
Observatory has been monitoring ...
Real-Time Audio Event Detection over a Low-Cost GPU Platform for Surveillance in Remote Elderly Monitoring
(MDPI, 2017-11-14)
The average of life expectancy of the population and the prioritization of authorities in active and home aging has increased recently. This has led governments and private organizations to increase ...
Construction and characterization of an omnidirectional parametric loudspeaker consisting of ultrasound transducers set on sphere
(Novem 2018, 2018)
Standard omnidirectional sound sources typically consist of conventional loudspeakers arranged in a dodecahedral configuration. For such devices, a microphone in a circular trajectory around the source ...
An FPGA Platform Proposal for Real-Time Acoustic Event Detection: Optimum Platform Implementation for Audio Recognition with Time Restrictions
(MDPI, 2016-11-14)
Nowadays, monitoring of people and events is a common matter in the street, in the industry or at home, and acoustic event detection is commonly used. This increases the knowledge of what is happening ...
homeSound: A High Performance Platform for Massive Data Acquisitionand Processing in Ambient Assisted Living Environments
(Proceedings of the 6th International Conference on Sensor Networks. SENSORNETS, Porto, 19-21 February 2017, 2017-02)
Las Smart Grids se presentan como una solución a la demanda de la gestión distribuida e inteligente de la energía, mejorando así las funciones de automatización, recolección ...
Remote Sensor Data Transmission from Antarctica to Spain with a Long-Haul HF Ionospheric Link
(1st International Electronic Conference on Remote Sensing, 2015)
The geophysical observatory in the Antarctic Spanish Station Juan Carlos I (BAE), on Livingston Island (62.6S, 60.4W), has been monitoring the magnetic field in the Antarctic region for more than fifteen ...
