Modelagem numérica para análise térmica em painéis de vedação
Full text linkMonografiaOne of the challenges of civil construction is to provide a comfortable environmental, safe and nice aesthetically to user, that being capable of satisfying the necessity of the same. And connected to this, it is the different studies in search of methods and materials that favor the better comfort in the buildings. To build, the Engineer should to attend the different legal parameters and connected parameters to quality and to well-being of the user, attached to this, it is the thermal comfort, that can be defined as being a mental condition that express to satisfaction with the environmental that the close. Being thermal comfort means that the individual in conditions of normal clothes does not feel neither cold nor heat. Thus, this study has as objective to evaluate the thermal behavior of different panels of seal applied in civil construction work, through of numerical modeling using the software ABAQUS/CAE. For analyzing, it were choose 3 types of seal panels, being the panel in massive concrete of thickness of 10 cm, panel in conventional masonry of bricks 8 holes with thickness of 14 cm and for last was analyzed the panel of seal in apparent solid bricks with total thickness of wall in 14 cm. Thus, the results obtained describe as the heat flow go through the panel in analyze. Being thus, it haves that the panel in conventional masonry of bricks of 8 holes was the model that kept more distant of the limit value of thermal transmittance, where the calculated value corresponds to 57,68% of the limit of standard, this it occurred due to empty in the interior of the masonry (the holes) where the same are filled with air, of this form enables a less passage of heat. Altogether, it concludes that three models analyzed in this study attended the parameters of acceptance of NBR 15220-3:2005, where to calculate the thermal transmittance of each panel, it obtain that all are below of maximum limit of acceptance of the values. And that the panel of massive concrete of the class C25 it is next of the parameter that limits the use; however, still attend the strategy of the bioclimatic zoning 8, to which the city of Caraúbas is characterized.Um dos desafios da construção civil é proporcionar um ambiente confortável, seguro e esteticamente agradável ao usuário, que seja capaz de satisfazer as necessidades do mesmo. E ligado a isso estão os diferentes estudos em busca de métodos e materiais que favoreça o melhor conforto nas edificações. Ao construir, o engenheiro deve atender a diferentes parâmetros legais e parâmetros ligados a qualidade e ao bem-estar dos usuários, atrelado a isso está o conforto térmico, que pode ser definido como sendo uma condição mental que expressa a satisfação com o ambiente que o cerca. Ter conforto térmico significa que o indivíduo em condições de roupas normais não se sente nem com frio nem com calor. Dessa forma, este trabalho tem como objetivo analisar o comportamento térmico de diferentes painéis de vedação aplicados em obras de construção civil, através de modelagem numérica utilizando o software ABAQUS/CAE. Para análise, foram escolhidos 3 tipos de painéis de vedação, sendo o painel em concreto maciço de espessura de 10 cm, painel em alvenaria convencional de tijolos de 8 furos com espessura de 14 cm e por último foi analisado o painel de vedação em tijolos maciços aparente com espessura total da parede em 14 cm. Com isso, os resultados obtidos descreveram como o fluxo de calor percorre os painéis em análise. Sendo assim, tem-se que o painel em alvenaria convencional de tijolos de 8 furos foi o modelo que se manteve mais distante do valor limite de transmitância térmica, onde a diferença do valor calculado corresponde a 57,68% do limite da norma, isso se deu devido os vazios no interior da alvenaria (os furos) onde os mesmos estão preenchidos com ar, dessa forma possibilita uma menor passagem de calor. De modo geral, conclui-se que os três modelos analisados nesse trabalho atenderam os parâmetros de aceitação da NBR 15220-3:2005, no qual ao calcular a transmitância térmica de cada painel, obteve-se que todos estão a baixo do limite máximo de aceitação dos valores. E que o painel de concreto maciço da classe C25 está próximo do parâmetro que limita o uso, porém ainda atende a estratégia do zoneamento bioclimático da zona 8, no qual a cidade de Caraúbas/RN está caracterizada.Trabalho não financiado por agência de fomento, ou autofinanciad
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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 textWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
