Análise das incidências de manifestações patológicas oriundas do recalque de fundações: estudo de caso na UFERSA-Angicos
Get PDFArtigoCivil construction is an area that has been expanding over time due to population development, linked to technological advancement. However, despite the use of new technologies in the construction field, in construction processes and materials, a significant index of pathological manifestations of the most varied species has been identified in buildings. Pathological manifestations can occur in the most varied ways and in the different elements that make up the buildings. Foundations are structural elements responsible for transmitting building loads to the ground, and when poorly executed, they reflect on other elements such as masonry in the form of cracks, cracks and other damage. These problems may arise due to the negligence in the stages of characterizing the soil behavior and investigation, analysis and design of the foundations, execution of the foundations. Thus, the present work presents a study on the incidence of pathological manifestations arising from the poor execution of the foundations of some blocks of the Federal Rural University of the Semi-Arid - Campus Angicos. With the study carried out, it was found cracks inclined at 45º, characteristics in which the cracks caused by repression present.A construção civil é uma área que vem ao longo do tempo se expandindo em decorrência do desenvolvimento populacional, atrelado ao avanço tecnológico. No entanto, apesar da utilização de novas tecnologias no campo construtivo, nos processos e materiais de construção, um significativo índice de manifestações patológicas das mais variadas espécies vem sendo identificadas nas edificações. As manifestações patológicas podem ocorrer das mais variadas formas e nos diversos elementos que compõe as edificações. As fundações são elementos estruturais responsáveis por transmitir as cargas das edificações para o solo, e quando mal executadas refletem em outros elementos como nas alvenarias em formas de fissuras, rachaduras e outros danos. Esses problemas podem surgir pela negligência nas etapas de caracterização do comportamento do solo e investigação, análise e projeto das fundações, execução das fundações. Dessa forma, o presente trabalho apresenta um estudo sobre as incidências de manifestações patológicas oriundas da má execução das fundações de alguns blocos da Universidade Federal Rural do Semi-Árido – Campus Angicos. Com o estudo realizado, foi encontrado fissuras inclinadas a 45º, características nas quais as fissuras provocadas por recalque apresentam.Trabalho não financiado por agência de fomento, ou autofinanciad
Funções complexas holomorfas e campos conformes no plano hiperbólico

hiperbólico. Monografia - Curso de Curso de Licenciatura em Matemática,

2022.O presente trabalho tem como objetivo, apresentar uma maneira mais simples de se obter
campos de vetores conformes (ou simplesmente, campos conformes) no plano hiperbólico,
utilizando-se das funções complexas holomorfas. Para isso estudamos as referidas funções
e a relação destas com os campos conformes no plano hiperbólico, utilizando a fórmula
da derivada de Lie para mudança conforme de métrica para demonstrar que através das
partes real e imaginária de uma função holomorfa, podemos construir exemplos de campos
conformes no plano hiperbólico. Do mesmo modo, mostramos que a partir das funções
componentes de um campo conforme no plano hiperbólico é possível obter uma função
complexa holomorfa. Por fim, demonstramos alguns resultados, entre eles, que um campo
é conforme no plano hiperbólico se, e somente se, o mesmo for conforme no semiplano
superior do plano Euclidiano munido com a métrica canônica e que um campo homotético
no plano hiperbólico será um campo de Killing
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
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
