Dual-mode soft-transition control for single-phase grid-connected photovoltaic inverters
(IEEE, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
Single-phase grid-connected inverters for photovoltaic power generation have been strongly analysed for improvement. Dual-mode control for two-stage inverters makes it possible to improve the efficiency by alternating ...
Using modelling techniques to analyze urban freight distribution. A case study in Pamplona (Spain)
(Elsevier, 2018)
info:eu-repo/semantics/conferenceObject,
The city of Pamplona, in Spain, is currently experiencing several changes regarding sustainable mobility such as pedestrianization of some streets in the city center, and access control to the Old Town for motor vehicles ...
All fiber interferometer for ice detection
(Optica Publishing Group, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
This work presents an etched single-mode - multimode - single-mode structure that detects the solid-to-liquid change of state of the water due to an increased refractive index sensitivity within the 1.308 - 1.321 RIU range
Linearly-configured BOCDA system with large modulation amplitude using dual-probe wave
(Optical Society of America, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
We present and experimentally demonstrated a linearly-configured Brillouin optical correlation domain analysis (LC-BOCDA) system that allows large modulation amplitude (Δf) based on a dual probe wave and the control of ...
Ramp-rate control in large PV plants: battery vs. short-term forecast
(2018)
info:eu-repo/semantics/conferenceObject,
The changeability in the power produced by utility-scale PV plants caused by shadows due to passing clouds can compromise grid stability. Traditionally, some kind of energy storage systems (ESS) is proposed as the solution ...
Ultra-long (275 km) random distributed feedback fiber laser for remote sensor monitoring
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
An interferometric sensor located 275 km away from the monitoring station has been interrogated by a double-pumped random distributed feedback fiber laser, reaching the longest distance in fiber optic remote sensing reported ...
High sensitivity fiber-optic liquid level sensor using biconical tapered fibers
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A liquid level sensor is presented using a biconical tapered standard single-mode fiber, being its main characteristic an outstanding sensitivity for a low cost transducer. Temperature compensation is enabled with the same ...
Gamma radiation measurements using an optical fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A fiber ring laser cavity configuration was used to analyze the effect of gamma-irradiation over the performance of different types of erbium doped fibers. Preliminary results validates this method to monitor gamma-radiation ...
Microstructured optical fiber sensor for soil moisture measurements
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A discrete sensor based on a Sn0₂-FP (Fabry-Pérot) cavity is presented and characterized in real soil conditions. Results are compared, for the first time to our knowledge, with a commercial capacitive sensor and gravimetric ...
Optical fiber immunosensors optimized with cladding etching and ITO nanodeposition
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Etched optical fiber immunosensors, with and without ITO nanodeposition, have been developed. The performance of these immunosensors has been assessed implementing an immunoassay. The sensitivity of the mmnunosensor increased ...
