Effects of the COVID-19 Pandemic on Sports Entrepreneurship
2020
Sports entrepreneurship has been considered an important part of sports organisations when overcoming crisis situations. The aim of this study is to determine the impact of the crisis derived from COVID-19 on sports entrepreneurship and whether there are differences in the prediction of entrepreneurship on service quality in non-profit sports clubs. To this end, 145 sports clubs were analysed before and after the outbreak of the virus in society. Paired sample-t tests were carried out to determine the differences in variables studied before (Time I) and after (Time II) the COVID-19 outbreak, and correlations and hierarchical linear regressions were used to analyse the relationship between t…
Partially implicit Runge-Kutta methods for wave-like equations
2012
In this work we present a new class of Runge-Kutta (RK) methods for solving systems of hyperbolic equations with a particular structure, generalization of a wave-equation. The new methods are {\it partially implicit} in the sense that a proper subset of the equations of the system contains some terms which are treated implicitly. These methods can be viewed as a particular case of the implicit-explicit (IMEX) RK methods for systems of equations with wave-like structure. For these systems, the optimal methods with the new structure are easier to derive than the IMEX ones, specially when aiming at higher-order (up to fourth-order in this work). The methods are constructed considering the clas…
A Geometrical Three-Ring-Based Model for MIMO Mobile-to-Mobile Fading Channels in Cooperative Networks
2011
Published version of an article published in the journal: Eurasip Journal on Advances in Signal Processing. Also available from the publisher at: http://dx.doi.org/10.1155/2011/892871. OA This paper deals with the modeling and analysis of narrowband multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) fading channels in relay-based cooperative networks. In the transmission links from the source mobile station to the destination mobile station via the mobile relay, non-line-of-sight (NLOS) propagation conditions are taken into account. A stochastic narrowband MIMO M2M reference channel model is derived from the geometrical three-ring scattering model, where it is assumed that an infi…
Designing the 5G network infrastructure: a flexible and reconfigurable architecture based on context and content information
2018
5G networks will have to offer extremely high volumes of content, compared to those of today’s. Moreover, they will have to support heterogeneous traffics, including machine-to-machine, generated by a massive volume of Internet-of-Things devices. Traffic demands will be variable in time and space. In this work, we argue that all this can be achieved in a cost-effective way if the network is flexible and reconfigurable. We present the Flex5Gware network architecture, designed to meet the above requirements. Moreover, we discuss the links between flexibility and reconfigurability, on the one side, and context awareness and content awareness, on the other; we show how two of the building…
Sheet Bending Modelling for AA 5083 Aluminium Alloy
1995
An extensive investigation of the V- and U-die bending processes of AA 5083 aluminium alloy has been performed by means of the finite element method and the experimental tests. The predicted results, in terms of elastic springback and loads, were compared with the experimental ones in similar conditions. At a given punch stroke, the springback ratio K increases with the sheet thickness, and, at a constant sheet thickness, K increases with the punch stroke. The comparison between predicted and experimental K values shows an excellent agreement in all the ranges of punch stroke and sheet thickness investigated. A very good agreement between the predicted bending forces and the experimental on…
1983-1985 Primeras leyes de la Generalitat Valenciana: La Ley del Gobierno Valenciano. Ley de coordinación de las Diputaciones. Proyecto de Ley de co…

La creación de la Generalitat Valenciana, como institución de nueva creación en base a la Constitución de 1978 y la aprobación del Estatuto de autonomía de la CV de 1 de julio de 1982, tendría que desarrollar la legislación derivada de las competencias estatutarias. En este capítulo nos referimos a tres leyes: La Ley del Gobierno Valenciano y el Reglamento de la Conselleria de la Presidencia; Ley de coordinación de las Diputaciones y el recurso de la ley de coordinación de diputaciones en el Tribunal Constitucional, su aprobación y como el Consell fija las Directrices de Coordinación de las Diputaciones. Por último, la Ley de comarcalización. La Generalitat tendrá que legislar y reglamentar…
