The use of boundary element method in soil-structure interaction analysis
No full textBu çalışmada, iki malzemeli kompozitin dinamik analizi için yerel olmayan sınır şartlarını içeren sınır eleman formülasyonu yapılmıştır. Formülasyon, tabakalı zeminleri içeren yapı-zemin etkileşim problemlerine uygulanmıştır. Fourier dönüşüm uzayında yapılan formülasyonda, sabit eleman yaklaşımı kullanılmıştır. Yapılan formülasyona dayalı iki ve üç boyutlu elastodinamik problemlerinin çözümü için genel amaçlı iki bilgisayar programı hazırlanmıştır. Fourier dönüşüm uzayında dinamik analiz yapan bu programlar yardımıyla, frekansa küçük değerler verilerek statik analiz de yapılabilmektedir. Hazırlanan programlar ile çözülen iki adet yapı-zemin etkileşim probleminin sonuçları, literatürde verilen sonuçlarla karşılaştırılmıştır.In this study, a boundary element formulation having nonlocal boundary conditions is presented for the dynamic analysis of a two-phase composite. The formulation is applied to soil-structure interaction problems including layered soil. The formulation is performed in Fourier transform space by using constant element model. Based on the formulation presented in this study, two general purpose computer programs are developed for two and three dimensional elastodynamic problems. The programs perform the analysis in Fourier transform space and can also be used for static analysis by assigning a small value to the frequency. The results of two soil-structure interaction problems obtained using the programs are compared with those in the literature

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
A boundary element model for dynamic analysis of two-phase and three-phase composites
No full textBu çalışmada, iki malzemeli kompozitin dinamik analizi için, yerel olmayan sınır şartlarını içeren sınır eleman formülasyonu yapılmıştır. Formülasyonda kullanılan yerel olmayan sınır şartları, üç malzemeli kompozitin analizinin yapılmasına imkan vermektedir. Fourier dönüşüm uzayında yapılan formülasyonda, sabit eleman yaklaşımı kullanılmıştır. Yapılan formülasyona dayalı; iki boyutlu analiz için CD2NL ve üç boyutlu analiz için CD3NL isimli, genel amaçlı iki bilgisayar programı hazırlanmıştır. Fourier dönüşüm uzayında dinamik analiz yapan bu programlar yardımıyla, frekansa küçük değerler verilerek statik analiz de yapılabilmektedir. Hazırlanan programlar ile çözülen problemlerin sonuçları, literatürde verilen sonuçlarla karşılaştırılmıştır.In this study, a boundary element formulation having nonlocal boundary conditions is presented for the dynamic analysis of a two-phase composite. Nonlocal boundary conditions, used in the formulation, make it possible to analyze a three-phase composite. The formulation is performed in Fourier transform space using a constant element model. Based on the formulation presented in this study, two general purpose computer programs are developed, namely, CD2NL (for two-dimensional analysis) and CD3NL (for three-dimensional analysis). The programs perform the analysis in Fourier transform space and can also be used for static analysis by assigning a small value to the frequency. The results of some benchmark problems obtained using the programs are compared with those in the literature
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
