Performance analysis of an existing reinforced concrete building with linear and non-linear analysis methods
Full text linkIn this study, we aim to evaluate performance of an existing reinforced concrete building using different analysis methods, such as linear and nonlinear methods and compare its results accordingly to highlight the importance of choosing the appropriate analysis method in performance evaluation of existing buildings. For this study we examined an existing reinforced concrete building located in İskenderun. Analysis models were created in accordance with the building's existing architectural and structural formwork plans. Missing data was completed by considering the minimum requirements of relevant codes and standards. The Modal Response Spectrum Method was used as the linear analysis method, while nonlinear analysis methods included Modal Pushover Analysis and Time History Analysis based on modal solution type. The current condition of the structure was evaluated within the framework of the Turkish Building Earthquake Code 2018 (TBEC-2018). According to linear modal response spectrum analysis method, the structure was generally evaluated at the Controlled Damage Performance Level. As a result of the nonlinear modal pushover analysis, it was determined that the structure was generally evaluated at the Collapse State Performance Level. Based on this nonlinear time history analysis, the structure was evaluated at the Controlled Damage Performance Level. Significant differences were observed between the performance levels obtained using different analysis methods. This highlights that the choice of analysis method has a direct impact on the assessment of structural safety. This study highlights the comparative results of various methods that can be used in the performance analysis of existing structures and emphasizes the importance of selecting the appropriate method.Bu tez çalışmasında, mevcut bir betonarme binanın, lineer ve lineer olmayan, farklı analiz yöntemleri kullanarak performans analizini yapıp sonuçlarını karşılaştırarak, mevcut binaların performans değerlendirilmesinde uygun analiz yönteminin seçiminin önemini vurgulamayı amaçladık. Bu çalışma için İskenderun'da bulunan betonarme bir binayı inceledik. Yapının mevcut mimari ve kalıp planlarına uygun olarak analiz modelleri oluşturulmuştur. Eksik veriler, ilgili yönetmelik ve standartların minimum koşulları göz önüne alınarak tamamlanmıştır. Doğrusal analiz yöntemi olarak Mod Birleştirme Yöntemi, doğrusal olmayan analiz yöntemleri olarak ise çok modlu itme yöntemlerinden olan Modal İtme Analizi ve Zaman Tanım Alanında Modal Analiz yöntemleri kullanılmıştır. Yapının mevcut durumu, Türkiye Bina Deprem Yönetmeliği 2018 (TBEC-2018) çerçevesinde değerlendirilmiştir. Mod birleştirme yöntemi ile yapılan analize göre yapı, genel olarak Kontrollü Hasar Performans Düzeyinde değerlendirilmiştir. Doğrusal olmayan çok modlu itme analizi sonucunda ise yapının genel olarak Göçme Durumu Performans Düzeyinde olduğu belirlenmiştir. Doğrusal olmayan zaman tanım alanında yapılan analizlere göre ise yapı, Kontrollü Hasar Performans Düzeyinde değerlendirilmiştir. Farklı analiz yöntemleriyle elde edilen performans düzeyleri arasında önemli farklılıklar gözlemlenmiştir. Bu durum, analiz yöntemi seçiminin yapısal güvenliğin değerlendirilmesi üzerinde doğrudan etkili olduğunu ortaya koymaktadır. Analiz sonuçları, farklı analiz yöntemleri sonucu ortaya çıkan performans düzeyleri belirlenmiş; ortaya çıkan sonuçlar karşılaştırmalı olarak değerlendirilmiştir. Bu çalışma, mevcut yapıların performans analizinde kullanılabilecek yöntemlerin sonuçlarını karşılaştırmalı bir şekilde ortaya koyarak, doğru yöntem seçiminin önemine dikkat çekmektedir
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.
