Liquid level sensor based on dynamic Fabry–Perot interferometers in processed capillary fiber
(Springer Nature, 2021)
info:eu-repo/semantics/article,
In this work, a novel optical fiber sensor capable of measuring both the liquid level and its refractive
index is designed, manufactured and demonstrated through simulations and experimentally. For
this, a silica capillary ...
Single longitudinal mode lasers by using artificially controlled backscattering erbium doped fibers
(IEEE, 2021)
info:eu-repo/semantics/article,
In this work, we propose and experimentally demonstrate a new distributed short linear cavity fiber laser. At one of the cavity ends, fabricated by a commercial femtosecond fiber laser chirped pulse
amplfier, an artificially ...
Mode transitions and thickness measurements during deposition of nanoscale TiO2 coatings on tilted fiber Bragg gratings
(IEEE, 2022)
Artículo / Artikulua,
The mode transition is a phenomenon observed in
thin film coated long period fiber gratings (LPGs) and singlemode multimode single-mode (SMS) fibers for certain values of
the coating thickness and refractive index, ...
Performance evaluation of spatial modulation patterns in compressive sensing terahertz imaging
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Terahertz (THz) imaging traditionally uses pixel-to-pixel mechanical raster scanning, which is slow and limits the resolution and potential applications. Compressive Sensing Terahertz (CS-THz) imaging has the potential to ...
Applying d-XChoquet integrals in classification problems
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Several generalizations of the Choquet integral have been applied in the Fuzzy Reasoning Method (FRM) of Fuzzy Rule-Based Classification Systems (FRBCS's) to improve its performance. Additionally, to achieve that goal, ...
Analysis and modelling of calendar ageing in second-life lithium-ion batteries from electric vehicles
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
The reuse of Li-ion batteries from electric vehicles
is a promising alternative to recycling nowadays. However, the
technical and economic viability of these second-life (SL) batteries
is not yet clear. Degradation ...
Momentum considerations inside near-zero index materials
(Springer Nature, 2022)
Artículo / Artikulua,
Near-zero index (NZI) materials, i.e., materials having a phase refractive index close to zero, are known to enhance or inhibit light-matter interactions. Most theoretical derivations of fundamental radiative processes ...
Constructing interval-valued fuzzy material implication functions derived from general interval-valued grouping functions
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Grouping functions and their dual counterpart,
overlap functions, have drawn the attention of many authors,
mainly because they constitute a richer class of operators compared to other types of aggregation functions. ...
Noise in coherently radiating periodic structures beam forming networks
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Following the noise wave theory, beam forming networks based on Coherently Radiating Periodic Structures (CORPS-BFN) are analysed and proven to be capable of enhancing the Signal to Noise Ratio of the system by analogically ...
Development of a water flow and velocity optical fiber sensor for field testing
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
A water flow and velocity fiber optic sensor system was developed and tested. The sensing head was especially developed and ruggedized to measure velocities at different depths, in order to calculate the discharge in channels.
