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 ...
Optimal strain gauge configurations for the estimation of mechanical loads in the main shaft of HAWT
(IOP Publishing, 2020)
info:eu-repo/semantics/conferenceObject,
In Structural Health Monitoring of wind turbines, measuring the mechanical loads is a key issue. The customary techniques for this task use a full-bridge strain gauge configuration to measure each of the six load components ...
Compact bull's-eye antenna in ridge gap waveguide with circular polarization at 60 GHz
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
In this work, a Bull's-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology, working in the millimeter-wave band (60 GHz) is numerically and experimentally demonstrated. The structure ...
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 ...
A biased-randomized learnheuristic for solving the team orienteering problem with dynamic rewards
(Elsevier, 2020)
info:eu-repo/semantics/conferenceObject,
In this paper we discuss the team orienteering problem (TOP) with dynamic inputs. In the static version of the TOP, a fixed reward is obtained after visiting each node. Hence, given a limited fleet of vehicles and a threshold ...
Analytical modeling of high-frequency winding loss in round-wire toroidal inductors
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
Toroidal inductors are present in many different industrial applications, thus, still receive researchers' attention. AC winding loss in these inductors have become a major issue in the design process, since switching ...
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.
