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 ... -
Garantía de calidad de servicio basada en la predicción del ancho de banda
This paper presents the architecture and performance evaluation of a neuronal estimator to predict network load in communication networks. System benchmarks are tested with real network traffic picked up from the 155 Mbps ... -
Gated local adaptive binarization using supervised learning
(CEUR Workshop Proceedings (CEUR-WS.org), 2021) Contribución a congreso / Biltzarrerako ekarpenaImage thresholding is one of the most popular problems in image processing. However, changes inlightning and contrast in an image can cause trouble for the existing algorithms that use a global threshold for all the image. ... -
Gaussian beam propagation versus Huygens method in non-paraxial conditions
In this paper, we present a study about the difference between Gaussian beam propagation and Huygens method to obtain the radiation pattern in the case of non-paraxial conditions. We fix a way to determine the error in the ... -
Gaussian profiled horn antennas
In many different applications parameters such efficiency, gain, directivity, etc., are really critical. By using the Gaussian techniques presented here, the radiating features of existing horn antenna systems can be ... -
Gaze estimation problem tackled through synthetic images
(Association for Computing Machinery (ACM), 2020) Contribución a congreso / Biltzarrerako ekarpenaIn 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 ... -
Gender analysis on the Ph.D. theses defended in Spain in the field of Optics and Photonics
Unconscious perceptions and decisions are influenced by gender bias. In this work, we provide an exhaustive data analysis of the Ph.D. theses defended in the field of optics and photonics in Spain by filtering key descriptors ... -
Gender distress: academe and mothering
Revisiting mothering as a personal, social, political and economical problem. Key object of study in feminist theories. Today becomes a topic of debate in social sciences. This research looks at the difficulties faced by ... -
Gender stereotyping impact in facial expression recognition
Facial Expression Recognition (FER) uses images of faces to identify the emotional state of users, allowing for a closer interaction between humans and autonomous systems. Unfortunately, as the images naturally integrate ... -
Generación del modo HE11 a partir de una guía circular lisa monomodo
In this paper, we present an original taper design to obtain the HE11 corrugated circular waveguide mode exciting with a pure TE11 monomode smooth circular waveguide mode. The proposed corrugated taper has a longitudinal ... -
General admissibly ordered interval-valued overlap functions
(CEUR Workshop Proceedings (CEUR-WS.org), 2021) Contribución a congreso / Biltzarrerako ekarpenaOverlap functions are a class of aggregation functions that measure the verlapping degree between two values. They have been successfully applied in several problems in which associativity is not required, such as ... -
A general beam-forming network made with CORPS
A new beam-forming network concept is introduced. This network is based in the design principles of CORPS. The new proposed structure presents an improvement in design over the traditional beam-forming network since, ... -
General grouping functions
Some aggregation functions that are not necessarily associative, namely overlap and grouping functions, have called the attention of many researchers in the recent past. This is probably due to the fact that they are a ... -
Generalization of QL-operators based on general overlap and general grouping functions
Firstly, this work discusses the main conditions guarantying that general overlap (grouping) functions can be obtained from n-dimensional overlap (grouping) functions. Focusing on QL-implications, which are usually ... -
The generalized bode criterion: application to the dc voltage control of a three-phase photovoltaic grid-tied inverter
As renewable energies are becoming more important in the electrical generation system, power electronic converters are facing new design issues related not only to their components but also to their control loops. In this ... -
