Análise dos efeitos decorrentes de tormentas TS em estruturas reticuladas
Get PDFTCC (graduação) - Universidade Federal de Santa Catarina. Centro Tecnológico. Engenharia Civil.Este trabalho foi elaborado com o objetivo de propor o modelo mais adequado de perfil de velocidades de ventos para obtenção de forças oriundas de linhas de tormenta TS ou ThunderStorm em uma estrutura reticulada além de uma comparação com o modelo atual de norma ABNT NBR 6123:1988 – Forças devidas ao vento em edificações. Tormentas TS são fenômenos atmosféricos causados por nuvens do tipo cúmulo-nimbo ou no latim cumulonimbus, que causam fortes jatos verticais descendentes de vento localizados e em contato com o solo se deslocam para todas as direções e com velocidades variadas. O dimensionamento de estruturas reticuladas, em relação aos efeitos do vento segue a norma ABNT NBR 6123:1988 – Forças devidas ao vento em edificações, porém o tratamento de uma Tormenta TS requer uma análise mais sofisticada, pois uma Tormenta TS possui características singulares que a diferem de outros eventos de ventos. Será desenvolvido neste trabalho um estudo comparativo entre um modelo probabilístico que descreve uma tormenta TS e o modelo da NBR 6123:1988 em uma estrutura reticulada e uma análise dos possíveis perfis de velocidade de uma tormenta TS. A estrutura será submetida a dois diferentes carregamentos, de acordo com os modelos descritos anteriormente. Os resultados dos dois carregamentos são apresentados e discutidos além da análise dos possíveis perfis de velocidades apresentados

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
