    Desarrollo de metodologías para la realización de ensayos de bastidores de Bogie según UNE-EN 13749

    [ES] Dentro del proceso de homologación de los vehículos ferroviarios, y con el fin de garantizar la integridad estructural de los bogies, deben realizarse un conjunto de tests que se recogen en la norma UNE-EN 13749. Los ensayos consisten en la aplicación de cargas (mayoradas) que se producen en servicio sobre el bastidor del bogie. Para ello se llevan a cabo pruebas de tipo estático que pueden llevar al fallo por fluencia, y otras en las que las fuerzas varían en el tiempo con el fin de determinar el comportamiento a fatiga. Mediante el estudio de los ensayos contemplados en la norma UNE-EN 13749, se pretende desarrollar criterios de diseño de los sistemas de fijación del bastidor a la bancada y de los útiles de aplicación de cargas, analizando los sistemas disponibles en el banco de ensayos del Instituto de Tecnología de Materiales de la Universidad Politécnica de Valencia. Los útiles de ensayo permiten aplicar los esfuerzos desde los actuadores hasta el bastidor, y conducir las reacciones desde el bastidor hasta la bancada. Ello debe realizarse de forma análoga a como se producen en el vehículo. Finalmente se realizará una aplicación de la metodología desarrollada atendiendo a un protocolo real de ensayo.[EN] In the process of railway vehicles approval, and in order to ensure the structural integrity of the bogies, it shall do a set of tests included in the standard UNE-EN 13749. The assays involve the application of loads (factored) produced in operation on the bogie frame. For this, static tests that can lead to failure by creep are performed, and others which forces change with time in order to set the fatigue behavior. Through the study of the tests covered by the standard UNE-EN 13749 and analyzing the available systems on the testing bench of Materials Technology Institute of the Polytechnic University of Valencia, it is intended to develop design criteria for frame fixing systems to the bench and the fixture for load application. The test tools allow applying the efforts from the actuators to the frame, and transmitting the reactions from the frame to the bench. This must be done in the same way that occurs during the life of vehicle. Finally there will be an application of the methodology developed in response to a real protocol test.[CA] Dins del procés d'homologació dels vehicles ferroviaris, i per tal de garantir la integritat estructural dels bogies, han de realitzar un conjunt de proves que es recullen a la norma UNE-EN 13749.

    Extrapolation and Application of Standard EN 13749 in Strength Analysis of Locomotive Axle-Box Body

    No full text
    According to existing standards for axle-box test not covering check and analysis of axle-box body, application scope, force types, and load cases were compared among several test standards for bogie frames. It was revealed that standard EN 13749 had the characteristics of wide variety of bogie categories, full consideration to loads, and definite method for force combination, which was suitable for extrapolation and application in strength assessment of axle-box body. During the extrapolating process of standard, the difference in force bearing way, magnitude and kinds of loads between axle-box body and frame were fully considered, so that the force types and the load cases were determined for strength calculation of axle-box body reasonably. Furthermore, with the guide of the extrapolated standard EN 13749, static and fatigue strength analysis for the axle-box body of certain exporting locomotive was accomplished

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
