Compact antennas in ridge gap waveguide with circular polarization
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this paper, two compact antennas in Ridge Gap Waveguide (RGW) technology, working at 60 GHz, with a high-purity circular polarization (CP) within a broad bandwidth are manufactured and measured. The antennas are fed ...
Compact optical fiber lasers and optical fiber sensors assisted by femtosecond laser inscription of plane-by-plane FBGs
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
Development of a high temperature sensor based on optical fiber l aser generated from a cavity of reduced dimensions (43 mm) in Er-doped fiber. The mirror FBGs have been inscribed with femtosecond laser using the slit beam ...
In-field torsion measurements on solar trackers using fiber optic sensors
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
In-field torsion measurements on solar trackers using fiber Bragg gratings are presented. 45 FBG sensors have been deployed in an operational solar energy plant to study the mechanical response of the structure to wind.
Enhanced optical fiber lasers and optical fiber sensors assisted by micro-drilled optical fibers
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
Enhanced OFS assisted by micro-drilled optical fibers acting as mirrors are
demonstrated. Strain sensitivity improved more than one order of magnitude in comparison
with FBG sensors using a 50 μm-waist micro-drilled taper ...
On the technical reliability of lithium-ion batteries in a zero emission polar expedition
(IEEE, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
This contribution presents a technical analysis of the Lithium-ion batteries (LIBs) used in the WindSled project. In this project, an expedition has been carried out by means of a 0-emission vehicle that have covered more ...
Synthetic wind speed generation for the simulation of realistic diurnal cycles
(IOP Publishing, 2020)
info:eu-repo/semantics/conferenceObject,
Synthetic wind-speed generators can provide a detailed characterisation of the wind variability at different time scales. A keen interest in the availability of synthetic wind speeds has recently risen in wind power modelling ...
Gaze estimation problem tackled through synthetic images
(Association for Computing Machinery (ACM), 2020)
info:eu-repo/semantics/conferenceObject,
In this paper, we evaluate a synthetic framework to be used in the field of gaze estimation employing deep learning techniques. The lack of sufficient annotated data could be overcome by the utilization of a synthetic ...
Distributed strain sensing with large dynamic range based on two-wavelength phase-sensitive OTDR
(Optica Publishing Group, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate the use of two-wavelengths to enhance the dynamic range in phase-sensitive OTDR vibration sensors. The system overcomes the phase wrapping con- strains by the synthesis of an equivalent wavelength measurement.
Active control for medium-frequency transformers flux-balancing in a novel three-phase topology for cascaded conversion structures
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
Efficiency and power density are important parameters in the design of power electronics converters. In many applications, low-frequency transformers are being substituted for medium-frequency and high-frequency transformers ...
Fiber-based label-free D-dimer detection for early diagnosis of venous thromboembolism
(SPIE, 2020)
info:eu-repo/semantics/conferenceObject,
D-dimer is a useful diagnostic biomarker for deep vein thrombosis or pulmonary embolism, collectively referred to as venous thromboembolism (VTE). The ability to detect in real-time the amount of D-dimer with a fast and ...
