Dynamic Structural Analysis of the 9516 Transport Package
No full textThis paper presents the structural dynamic analysis of the 9516 package subjected to two hypothetical accidents in sequence: (1) the 30-ft drop test and (2) the puncture test. The analysis is performed with the general-purpose finite element analysis computer code, ABAQUS, using explicit integration. The 9516 package consists of a containment vessel placed inside a cask mounted inside a steel cage, which acts as the impact limiter and the personnel shield. The cask has a bolted closure that provides the confinement to the containment vessel. The closure bolts initially were modeled with one-dimensional elastic connector elements bearing only the axial loads, which was adequate for the analysis of the drop test. However, the closure lid experienced significant bending during the puncture test, implying bending load acting on the closure bolts. Therefore, the closure bolts were modeled by using solid elements in a refined model so that the response to the bending load during the puncture test can be simulated. The results of the analysis showed that the closure bolts experience significant bending during the puncture test. For model validation, a comparison between the analysis results and the test results for rigid body accelerations of the package is presented. The results of the analysis based on the refined model show that the maximum stress intensities in the closure bolts, containment vessel, and cask are lower than the corresponding allowable stresses specified in the American Society of Mechanical Engineering Boiler and Pressure Vessel Code.</jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
