Further empirical evidence on stochastic volatility models with jumps in returns
Using the Efficient Method of Moments we estimate a continuous time diffusion for the stochastic volatility of some international stock market indices that allows for possible jumps in returns. These jumps are needed for ... -
A further generalization of the Solow growth model: the role of the public sector
We develop in this paper an augmented version of the Solow (1956) growth model, including the role of government. The model leads to a non-monotonic relationship between the rate of growth of per capita output and government ... -
A further study of the kinetics of recrystallization and grain growth of cold rolled TWIP steel
Un estudio adicional de la cinética de recristalización y crecimiento de grano del acero twip laminado en frío. Muestras de acero TWIP laminadas en caliente en laboratorio de composición, 22% de Mn, 0,6% de C (% en masa) ... -
A fusion method for multi-valued data
In this paper we propose an extension of the notion of deviation-based aggregation function tailored to aggregate multidimensional data. Our objective is both to improve the results obtained by other methods that try to ... -
The fusion of Toxoplasma gondii SAG1 vaccine candidate to Leishmania infantum heat shock protein 83-kDa improves expression levels in tobacco chloroplasts
Chloroplast transformation technology has emerged as an alternative platform offering many advantages over nuclear transformation. SAG1 is the main surface antigen of the intracellular parasite Toxoplasma gondii and a ... -
Fútbol e ingeniería: evolución histórica de los terrenos de juego de campos y estadios del fútbol español a través del fútbol navarro
El fútbol ha evolucionado a lo largo de su historia en todos sus aspectos, siendo uno ellos, las superficies de juego y sus alrededores. Pero, ¿qué diferencias hay entre un terreno de juego actual, al de hace 20, 50 o 100 ... -
Future directions in international financial integration research. A crowdsourced perspective
This paper is the result of a crowdsourced effort to surface perspectives on the present and future direction of international finance. The authors are researchers in financial economics who attended the INFINITI 2017 ... -
Future smartphone: MIMO antenna system for 5G mobile terminals
In this article, an inverted L-shaped monopole eight elements Multiple Input Multiple Output (MIMO) antenna system is presented. The multi-antenna system is designed on a low cost 0.8 mm thick FR4 substrate having dimensions ... -
Futuros escenarios del management. Casos de éxito y evidencia empírica
Este documento persigue identificar tendencias que afecten al management del futuro. En concreto, se proponen cinco posibles: Industria 4.0, el Big Data, el Internet de las Cosas, la realidad virtual y la ciberseguridad. ... -
FUZZ-EQ: a data equalizer for boosting the discrimination power of fuzzy classifiers
The definition of linguistic terms is a critical part of the construction of any fuzzy classifier. Fuzzy partitioning methods (FPMs) range from simple uniform partitioning to sophisticated optimization algorithms. In this ... -
Fuzzy Arrovian theorems when preferences are strongly-connected
In this paper we study the aggregation of fuzzy preferences on non-necessarily finite societies. We characterize in terms of possibility and impossibility a family of models of strongly-connected preferences in which the ... -
A fuzzy association rule-based classifier for imbalanced classification problems
Imbalanced classification problems are attracting the attention of the research community because they are prevalent in real-world problems and they impose extra difficulties for learning methods. Fuzzy rule-based ... -
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 concept lattices and fuzzy relation equations in the retrieval processing of images and signals
This paper considers the introduced relations between fuzzy property-oriented concept lattices and fuzzy relation equations, on the one hand, and mathematical morphology, on the other hand, in the retrieval processing ... -
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 logic-based energy management system design for residential grid-connected microgrids
This paper presents the design of a low complexity fuzzy logic controller of only 25-rules to be embedded in an energy management system for a residential grid-connected microgrid including renewable energy sources and ... -
A fuzzy methodology for approaching fuzzy sets of the real line by fuzzy numbers
In this paper we introduce a novel methodology to face the problem of finding, for every fuzzy set of the real line, a fuzzy number which can be considered as an approximation of the first one in some reasonable sense. ... -
Fuzzy morphological operators in image processing
First of all, in this paper we propose a family of fuzzy implication operators, which the generalised Luckasiewicz´s one, and to analyse the impacts of Smets and Magrez properties on these operators. The result of this ... -
Fuzzy rule-based classification systems for multi-class problems using binary decomposition strategies: on the influence of n-dimensional overlap functions in the fuzzy reasoning method
Multi-class classification problems appear in a broad variety of real-world problems, e.g., medicine, genomics, bioinformatics, or computer vision. In this context, decomposition strategies are useful to increase the ... -
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 ...
