Comparative Experimental Study on the Dynamic and Static Stiffness of Sandy Soils Utilizing Alpan’s Empirical Approach
No full textStiffness parameters are very important and effective in the constitutive models used in finite element analysis. It is not easy or common to obtain these parameters in the laboratory. However, even if the modulus is determined in the small and medium deformation range, there is a need to make transitions in both static and dynamic parameters. In almost all studies, the Alpan approach is used for the relationship between static and dynamic moduli of elasticity. Therefore, a better understanding of this approach is required. In this study, the relationship between static and dynamic stiffness was determined by monotonic triaxial and resonant column tests on five different sand samples with different relative stiffness and grain distributions, and the results were compared with Alpan’s approach. It is not clear which of the initial or maximum modulus of elasticity (E0), unloading-reloading modulus (Eur) or secant modulus of elasticity (E50) are used by Alpan for static modulus of elasticity (Estat). Therefore, the coefficient Rsec = Estat/E50 was introduced and queried to indicate which Estat is a multiple of E50. In connection with this, the dynamic modulus of elasticity (Edyn) was calculated using the small deformation shear modulus (G0) obtained from resonant column experiments and assuming Poisson’s ratios (ν = 0.2, 0.3, 0.4). It was found that Alpan’s empirical approach achieved a significant degree of agreement for the sands in this study and the studies of other researchers. It was observed that the best agreement between dynamic and static stiffness ratio (Edyn/Estat) and static modulus of elasticity (Estat) for sand specimens in this study was obtained with υ = 0.2 and Rsec = 2. According to the experimental results, it is safe to say that Alpan’s empirical approach is still valid when the values of Poisson’s ratio and Estat in the very small deformation region are used. Since there are limited studies on Edyn/Estat ratio in the literature, it is thought that the findings in this paper will assist engineers and researchers. However, this work would also assist engineers in selecting appropriate stiffness parameters for calibrating constitutive models
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
Bazı özel durumlar için aşıt polinomların asimptotikleri
No full textCataloged from PDF version of article.Includes bibliographical references (leaves 129-141).We study the asymptotics of orthogonal and Chebyshev polynomials on fractals.
We consider generalized Julia sets in the sense of Br uck-B uger and weakly
equilibrium Cantor sets which was introduced in [62].
We give characterizations for Parreau-Widom condition and optimal smoothness
of the Green function for the weakly equilibrium Cantor sets. We also show
that, for small parameters, the corresponding Hausdor measure and the equilibrium
measure of a set from this family are mutually absolutely continuous.
We prove that the sequence of Widom-Hilbert factors for the equilibrium measure
of a non-polar compact subset of R is bounded below by 1. We give a
su cient condition for this sequence to be unbounded above.
We suggest de nitions for the Szeg}o class and the isospectral torus for a generic

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
Thermal particle creation in cosmological spacetimes: A stochastic approach

D 56, 4905 (1997)], Phys. Rev. D 57, 1317 (1998).The stochastic method based on the influence functional formalism introduced in an earlier paper to treat particle creation in near-uniformly accelerated detectors and collapsing masses is applied here to treat thermal and near-thermal radiance in certain types of cosmological expansions. It is indicated how the appearance of thermal radiance in different cosmological spacetimes and in the two apparently distinct classes of black hole and cosmological spacetimes can be understood under a unifying conceptual and methodological framework.Don Koks, B.

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
