    隨著積體電路技術的不斷發展,電路尺寸更小,性能更高,成本也變得越來越高。使用矽穿孔(TSV)技術的三維記憶體是一種新興的技術,相比平面積體電路有更高的性能和更低的功耗。然而三維記憶體的堆疊產量仍然是一個問題。 在這篇論文中,我們提出了一個改進自匈牙利方法(The Hungarian Method of Assignment)的新演算法對三維記憶體(3D Memory)進行晶圓到晶圓堆疊。實驗結果表明我們的算法可以在一個合理的時間內,給出較高的堆疊良率。As the process technology continues to evolve, IC become smaller and high performance, and the cost become higher. A 3D-IC uses Through Silicon Via (TSV) is an emerging technology, higher performance, and lower power consumption compared to planar ICs. However stacking yield is a problem of 3D-IC. In this thesis, we propose a new algorithm using improved from the hungarian method of assignment on the three-dimensional memory for wafer to wafer stacking. Our results show that our algorithm can be a reasonable amount of time, given the higher stacking yield.口試委員會審定書 # 誌謝 i 中文摘要 ii ABSTRACT iii CONTENTS iv LIST OF FIGURES vi LIST OF TABLES vii Chapter 1 Introduction 1 1.1 採用矽穿孔技術的三維積體電路 1 1.2 三維積體電路的堆疊技術 2 1.3 晶圓到晶圓堆疊的相關研究 3 1.4 論文目的 3 1.5 論文構成 3 Chapter 2 Preliminaries 5 2.1 指派問題 5 2.2 匈牙利方法 6 Chapter 3 The Proposed Method 12 3.1 三維記憶體堆疊問題 12 3.2 超平面覆蓋法 14 3.3 演算法的對稱性 19 3.4 相似度優先演算法 21 Chapter 4 Simulation Results 27 Chapter 5 Conclusions and Future Work 31 5.1 結論 31 5.2 未來工作 31 REFERENCE 3

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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
