On the stability criteria for inverter current control loops with LCL output filters and varying grid impedance
(IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
The use of LC and LCL filters and grid impedance variations are creating new challenges on the controller design for current control loops of photovoltaic and wind turbine inverters. In the design process, stability criteria ...
Brillouin optical time-domain analyzer for extended sensing range using probe dithering and cyclic coding
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We present an enhanced performance Brillouin optical time-domain analysis sensor that uses dual probes waves with optical frequency modulation and cyclic coding. The frequency modulation serves to increase the probe power ...
Enhancement of signal-to-noise ratio in Brillouin optical time domain analyzers by dual-probe detection
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a simple technique to enhance the signal-to-noise ratio (SNR) in Brillouin optical time-domain analysis sensors by the addition of gain and loss processes. The technique is based on the shift of the pump ...
Detection of ethanol in human breath using optical fiber long period grating coated with metal-organic frameworks
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
An optical fiber sensor for ethanol detection in exhaled breath has been developed. It has been fabricated by functionalizing a Long Period Grating with a metal-organic framework, ZIF-8. The sensor’s response was tested ...
Title enhancement of the sensitivity of a volatile organic compounds MOF-sensor by means of its structure
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we experimentally compare several core structures of Microstructured Optical Fibers (MOFs) for low-finesse Fabry-Pérot (FP) sensors. These sensors are designed for Volatile Organic Compounds (VOCs) measurements. ...
Etched and nanocoated SMS fiber sensor for detection of salinity concentration
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
An optical fibre refractometer has been developed by etching and deposition of a thin film of indium tin oxide (ITO) on a single-mode-multimode-single-mode (SMS) fibre structure. The interference between modes in this ...
Monitoring the etching process in LPFGs towards development of highly sensitive sensors
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the monitoring of the etching process up to a diameter of 30 µm of two LPFG structures has been compared, one of them had initially 125 µm, whereas the second one had 80 µm. By tracking the wavelength shift ...
The role of adults in children digital literacy
(Elsevier, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
Collected data from different studies show how users acquire great skills in terms of technology’s use, but they don’t gain such skills in a safe use of technology. The objective of this study is to identify the level of ...
Characterization of near-ground radio propagation channel for wireless sensor network with application in smart agriculture
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In this contribution, we present a narrowband radio channel model for a scenario wherein
the radio link operates under near-ground conditions, occurring on a ZigBee wireless sensor
networks applied to smart agriculture. ...
La sobreexpresión del gen ALDH7B4 alivia los efectos provocados por herbicidas inhibidores de la biosíntesis de aminoácidos
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
En este trabajo se ha profundizado en el conocimiento de los efectos fisiológicos provocados por los herbicidas imazamox y glifosato. En concreto, se ha estudiado el papel de la ALDH7B4, aldehído deshidrogenasa, que ...
