Full-space metasurface at millimeter-wave frequencies
Conventional metasurfaces provide control over the electromagnetic waves in a single working frequency operating either in transmission or reflection. Full-Space Metasurfaces (FSM) are an extension that allows operation ... -
Fuzzy clustering to encode contextual information in artistic image classification
Automatic art analysis comprises of utilizing diverse processing methods to classify and categorize works of art. When working with this kind of pictures, we have to take under consideration different considerations compared ... -
Fuzzy integrals for edge detection
(Springer, 2023) Contribución a congreso / Biltzarrerako ekarpenaIn this work, we compare different families of fuzzy integrals in the context of feature aggregation for edge detection. We analyze the behaviour of the Sugeno and Choquet integral and some of its generalizations. In ... -
Fuzzy sets complement-based gated recurrent unit
(CEUR Workshop Proceedings (CEUR-WS.org), 2021) Contribución a congreso / Biltzarrerako ekarpenaGated Recurrent Units (GRU) are neural network gated architectures that simplify other ones (suchas, LSTM) by joining gates mainly. For this, instead of using two gates, if𝑥is the first gate, standardoperation1−𝑥is used ... -
Fuzzy-based energy management of a residential electro-thermal microgrid based on power forecasting
In this paper, an energy management strategy based on microgrid power forecasting is applied to a residential grid-connected electro-thermal microgrid with the aim of smoothing the power profile exchanged with the grid. ... -
Fuzzy-based power exchange management between grid-tied interconnected residential microgrids
This paper presents a fuzzy-based power exchange management between two neighboring residential grid-connected microgrids comprising both photovoltaic generation and battery energy storage system (BESS). The proposed power ... -
Gain dependence of measured spectra in coherent Brillouin optical time-domain analysis sensors
We report on the effects of large pump pulse powers on Brillouin optical time-domain analysis (BOTDA) sensors based on phase-modulated probe wave and coherent detection. It is found that the large Brillouin gain that comes ... -
Gamma radiation measurements using an optical fiber laser
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 ... -
A gap waveguide fed circular polarization antennas in the millimeter wave range
In this work, a novel circular polarization (CP) antennas in ridge gap waveguide (RGW) working in the V-band of the millimeter-wave spectrum is presented. CP is generated in a simple and effective way by means of two ... -
