<p>This repository contains instructions for how to run the FEniCS MMS benchmarks described in the paper against regularized and penalized formulation (Eqn. 21). A plotting script to generate convergence rate figures is also included. </p>
<p>Set inv_lambda_const = 0 will perform benchmarks against the regularized but non-pernalized formulation (Eqn. 18) instead.</p>

Investigation into Yield Behavior of Fresh Cement Paste: Model and Experiment
Get PDFIn the present study, a yield stress model of cement paste is developed based on a theoretical approach. In this model, cement particles are assumed as rigid spheres uniformly distributed and suspended in water. The interparticle force is considered resulting from the electrostatic and dispersion forces of the cement particles. Two types of tests - a direct shear and a rheometer test - are performed on a group of cement pastes made with different water-cement ratios (w/c), and the results are used for verification of the validity of the newly developed model. The study demonstrates that the newly developed model can not only predict the yield behavior of cement pastes but also describe the correlations among the yield stresses obtained from different experimental methods.This article is published as Lu, Gang, and Kejin Wang.

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
A Study on the Writing of Lu Gang's Zhu-Zhi Ci and Eight Scenes Poetry in the Japanese Colonial Period ──Based on the Works of DaYe Poetry Recital Club
No full text[[abstract]]This study is based on Zhu-Zhi Ci and Eight Scenes Poetry of DaYe Poetry Recital Club in Lu Gang, probing into the literary situation of Lu Gang during the Japanese colonial period. As DaYe Poetry Recital Club is the most important classic poem club in Lu Gang, many local scholars gathered together for their poetic creation, and so their works became more representational. It is not only important to understand the life style of Lu Gang during the Japanese colonial period, but also further think the representative meaning of Zhu-Zhi Ci and Eight Scenes Poetry for Taiwan local literature. Here’s the brief introduction of this study:
Chapter one is to state the research motivation, method, framework, and the generation, region, subject of this study. Chapter two “The literary background and authors of Lu Gang Zhu-Zhi Ci and Eight Scenes Poetry during the Japanese colonial period” is to describe the changes of Zhu-Zhi Ci and Eight Scene poem in Taiwan, , followed with a narration on the foundation, members, activities and creation of the DaYe Poetry Recital Club of Lu Gang. Chapter three “Lu Gang local description in Lu Gang Zhu-Zhi Ci” is to discuss the relationship between regional character and the literary mode of Zhu-Zhi Ci, also including the analysis of people’s life style in Lu Gang and the characteristics of literature in the main text. There are two discussion points in chapter four “Lu Gang local description in Lu Gang Eight Scenes Poetry”, “Eight Scenes” and “Eight Scenes Poetry”. “Eight Scenes”, is to explore the development of Chang Hua Eight Scenes of Ching and Lu Kan Eight Scenes during the Japanese colonial period and after world war, and further understand the implicit significance of “Lu Gang Eight Scenes” during the Japanese colonial period. “Eight Scenes Poetry” is to delve the cultural guide of Lu Gang in “Lu Gang Eight Scenes Poetry”. Finally, the position of Lu Gang, which the scholars were trying to reposition under the change of the generation, and how did “Lu Gang Eight Scenes Poetry” of Japanese colonial period become the critical factor for tourist development of Lu Gang are the topics for discussion via these two researches. Chapter five “Analysis of significance of Lu Gang Zhu-Zhi Ci and Eight Scenes Poetry”, it’s to discuss how did the different modes, Lu Gang Zhu-Zhi Ci and Eight Scenes Poetry, represent a same theme and change the two political description modes into a medium of regional literature. Chapter six, “Result” is to generalize the literary situation and significance of Lu Gang DaYe Poetry Recital Club, then draw the conclusion.
