Object space line extraction Laplacian lines
No full textInspired by the recently developed theory on Laplacian-of-Gaussian edge, He Ying (2008) and his colleagues developed a theory which extracts the Laplacian lines of 3D objects. Most of the previous 3D line extraction methods are either view independent or computational expensive, which are not very suitable for real time rendering. Compared to these algorithms, the complex computation work in Laplacian line extraction algorithm is done before run time rendering. This project applies He’s theory on Laplacian lines and implements it using demo examples. Additionally, this paper proves the efficiency of Laplacian line extraction algorithm by measuring its real time rendering time.Bachelor of Engineering (Computer Science
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

No full text[[abstract]]本研究的主要目的在以九行人格理論為基礎，探討不同背景變項與九種人格型態的關
係，以及建立大學生在九行人格量表得分的常模，並考驗九行人格量表的信度與效度
，以提供輔導實務上的參考。
本研究以二十所公私大學暨獨立學院1479名大學生為對象，採用問卷調查法蒐集資料
。研究工具有「基本資料表」、「九行人格量表」、「大專人格測驗」、「特質焦慮
量表」。所得資料以單因子變異數分析、t 檢定、皮爾遜積差相關等統計方法加以考
驗。
研究結果發現：
一•不同背景變項在九行人格量表分數上的差異不大
除了男、女生在七個分量表分數有顯著差異外，不同學院、家庭子女數、排行、宗教
信仰等變項僅有少數組別的分數差異顯著，頗符合原理論的假設。
二•九行人格量表的信度與同時效度良好
