Why do female and male taekwondo athletes win the bout? An analysis based on the Olympic weight category and the result of the bout
2020
Combat sports such as taekwondo, where athletes compete against an opponent require control of technique and tactics, as well as knowing the optimal performance of opponents to win the bout. Therefore, the aim of the present study was to analyse the Olympic competitors (London Olympic Games), according to the weight category (fly, feather, light and heavy) and according to the performance in their fighting (winner vs. loser) in each gender. An observational methodology was used, following a nomothetic, follow-up and multidimensional design of 302 individual performances. The statistical analysis used an ANOVA and T Student test for comparing frequencies. The results obtained indicate signif…
APPLICATIONS OF DIMENSIONAL ANALYSIS AND SIMILARITY THEORY IN HYDRAULICS
2018
Technological process, however complex, can be broken down into a succession of distinct component processes, in which the input materials undergo changes in shape (mechanical processes), pressure, temperature, concentration, state of aggregation (physical processes) or structure molecular (chemical and biochemical processes). The unitary operations of most process phases in process industries are based on three fundamental processes: pulse transfer, heat transfer, and mass transfer
Bathymetry time series using high spatial resolution satellite images
2020
The use of the new generation of remote sensors, such as echo sounders and Global Navigation Satellite System (GNSS) receivers with differential correction installed in a drone, allows the acquisition of high-precision data in areas of shallow water, as in the case of the channel of the Encañizadas in the Mar Menor lagoon. This high precision information is the first step to develop the methodology to monitor the bathymetry of the Mar Menor channels. The use of high spatial resolution satellite images is the solution for monitoring many hydrological changes and it is the basis of the three-dimensional (3D) numerical models used to study transport over time, environmental variability, and wa…
REPLACER L'AUDITEUR AU COEUR DE SON METIER: UNE ETUDE EXPLORATOIRE SUR LE MARCHE FRANÇAIS
2012
The auditor's judgment, faces new stakes bound up to the industrialization of the audit process and to the development of the new information and communication technologies. These evolutions, complicate the audit practices and calling into question to the professional judgment exercise. The aim of our research is to contribute, to restore and to re-size the place granted to the professional judgment. To be made we led two studies: a qualitative study realized with a sample consisted of 22 auditors and a documentary study based on the booklet of The Green Paper on Audit Policy. The results show that there is a dialectical relation between the technical dimension and the human dimension of th…
Leadership Scale in football coaches: psychometric and descriptive study
2020
El liderazgo ha sido una de las variables de interés en la psicología aplicada al deporte. El Modelo Multidimensional de Liderazgo de Chelladurai y Saleh (1980) sirvió de base para la creación de la Leadership Sport Scale (LSS). La versión para entrenadores (LSS-3) presenta debate respecto a su estructura factorial y sus valores de fiabilidad. El objetivo de este estudio es ofrecer una solución factorial aceptable para la escala LSS-3 en versión española (Ruiz-Barquín y De la Vega, 2015) en una muestra de 326 entrenadores de fútbol, varones, con edades comprendidas entre los 17 y 59 años y evaluar sus cualidades psicométricas. En segundo lugar, se investigan las posibles diferencias en las …
L'esprit de famille - Après les réformes du droit des successions et des libéralités
2007
Le droit des successions et des liberalites vient de connaitre, coup sur coup, deux reformes qui renovent profondement la matiere. La famille a cause de mort qui se dessine au travers des regles de l'heritage n'est plus tout a fait la meme. La loi successorale prend en compte le resserrement de la famille autour du couple et des enfants, au detriment de la famille elargie. La solidarite familiale joue toujours son role au travers de la reserve successorale des enfants ou de creances alimentaires dont peuvent eventuellement beneficier les ascendants et les freres et soeurs. Toutefois, le droit nouveau fait une large place a la volonte du de cujus et l'esprit de famille doit necessairement s'…
Analyse morphologique de talwegs et comportement scalant : applications des dimensions non-entières à la géographie physique
1999
Morphological talweg analysis and scaling behaviour: applying non-integer dimension to physical geography. -- The organisation of the talweg network is fundamental to the erosion system on the silty loamy plateaux of north-western France. The morphology of the Pays de Caux is a good example of successive runoff concentration caused by the nesting of small dry valleys. These are inherited from a periglacial climate and their general direction is governed by tectonics. However the detailed pattern of these forms remains complex and without obvious explanation. Non-integer dimensions may offer a ceratin logic to this relatively chaotic pattern. This paper has therefore sought to demonstrate th…
Ledrappier-Young formula and exact dimensionality of self-affine measures
2017
In this paper, we solve the long standing open problem on exact dimensionality of self-affine measures on the plane. We show that every self-affine measure on the plane is exact dimensional regardless of the choice of the defining iterated function system. In higher dimensions, under certain assumptions, we prove that self-affine and quasi self-affine measures are exact dimensional. In both cases, the measures satisfy the Ledrappier-Young formula. peerReviewed
Replication Data for: Who can go back to work when the COVID-19 pandemic remits?
2020
The file contains the raw data that was used to make the calculations in the article "Who can go back to work when the COVID-19 pandemic remits?" and that allows to replicate it. Specifically, it contains the following: Corresponding to Social Security in Spain - Affiliates to Social Security in Spain in the month of February 2020, distributed by age and province. - Affiliates by sectors in the different regimes, distributed by provinces. February 2020. - Grouping of sectors according to the National Classification of Economic Activities. Corresponding to the effects of covid-19 - Cases and deaths by age in Spain on April 21, 2020 - Population in Spain by age - Total cases and dea…
