No full text本篇論文的目的，主要在發展一套交談式的電腦輔勵設計系統(Interactive Freeform
Modeling CAD System)m同時發展一套小型的繪圖核心系統(Graphical Kernel System)
簡稱G.K.S.做為電腦輔助設計的繪圖工具。
在電腦輔勵設計方面，則先以Bezier Curve With Fitting Points 的方式建立曲線，
而曲線Fitting Point 的輸入與修改，則以系統提供的Point Editor 來執行。我們先
以Point Editor 來產生一些剖面(Profiles) 曲線與切面曲線(Crosssections) ，再
以剖面曲線和怍面曲線為基本圖元，應用到曲面旋轉(Surface of Reveolution) ，
直軸設計(Rectilinear Axis Design) 及自然軸設計(Natural Axis Design) 三種設
計技巧上。使用者可利用系統提供的資料結構建立與修改副系統，輸入模式實體的組
合方式興組合物體的型態及相關的資料，讓系統製造出模式的圖形，使用者可依其圖
形加以修改，直到產生滿意，合乎理想的模式為止。此套系統很適合於機械上的零件
組合設計，亦可用來畫一些蓋術品，如花瓶、杯子……等。
在繪圖核心系統方面，G.K.S. 是一套圖際標準局(I.S.O.) 所定立的標準繪圖系統，
具有完整的繪圖功能，這些功能乃用來表現二度空間的觀視圖形。同時也提供了程式
與使用者間交談作用的功度，使用G.K.S. 將很容易地發展一些特殊用途及一般用途
的應用系統來，如資料繪圖、機械、建築的電腦輔助設計及一般的商業報表、製圖等
。繪圖核心系統之發展大致分為六大部分，分別設計，即一、繪圖輸出元件功能(Gr
aphic Output Primitives)；二、工作站(Work Station)；三、座標系統(Coordina
te System)；四、節段控制(Segment Control)；五Metafile 及六、輸出／入控制(I
/O Control)，六大部分。
此電腦輔助設計部分及繪圖核心系統統部分，均已在IBM 16 Bits 微電腦上發展成功
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.
