The Analysis of Channel Evolution after Dam Removal Combining Two Dimensional Hydraulic Sediment Transport Model and Stochastic Hydrology Simulation
No full text壩體移除會造成一系列的地形，地貌、泥砂運移、深槽線等變化。在研究上，應用解析方法計算泥砂量，並且提供一個概念性預測地貌變化。現今電腦科技的發達，利用一維水理以及輸砂數值模式模擬拆壩後的反應已經廣泛被接受。但一維模式在模擬當中使用平均的概念以至於無法全面的了解地形的演變。故，本研究採用二維水理輸砂模式(SRH-2D)應用在七家灣溪拆壩案例上。SRH-2D是由美國墾務局開發的二維水理輸砂軟體，數值方法使用平均深度的二維聖凡那方程式，可以計算穩態、非穩態、總輸沙量，以及提供多種輸砂公式。本研究認為壩體移除後，河川地貌影響的主要控制因素為水文條件，因此由Shot noise model建立序率水文合成序列，並結合定率水理輸砂軟體，利用過去實測流量資料找出該區域之的水文特性，基於序率水文條件探討壩體移除後河相改變，以序率的形式描述來自水文不確定性下的河川地貌變化，結果討論短、長時間下平均深度、深槽線、土方量的變化，並且用超越機率表示地形的變化。Dam removal will result in a series of river terrain changes, migration of sediment and other changes in river morphology. In recent, with the state of the art, utilizing one-dimensional hydraulic and sediment transport model to simulate the response after dam removal is common and widely accepted. However, it is highly limited in the model assumption and capacity and not able to provide a comprehensive analysis of channel evolution. On the other hand, an important factor dominates geomorphology after dam removal is hydrologic condition, most time is the discharge in channel. In hydrology, the uncertainty exists naturally, so cannot ideally be determined. Uncertainty is usually caused from high variance of hydrological phenomena in space, and leads to difference between simulation and real situation.
This study applies stochastic hydrological simulation and 2-dimenisonal hydraulic and sediment transport model to analysis channel morphology after dam removal. This study not only makes effort to evaluate to possibility of application of SRH-2D in dam removal simulations, which is a two-dimensional hydraulic, sediment, temperature, and vegetation model for river systems under development at the Bureau of Reclamation. We also combine with deterministic two-dimension hydraulic, sediment model and stochastic synthetic hydrologic time series. Taking the removal of the Chichiawan NO.1 dam as a case study, this study aims to quantify uncertainty of flow condition and has a stochastic prediction with probability of physical response of channel. This research provided a method to stochastically describe channel evolution after dam removal. This method contributes a better understanding in hydrology uncertainty with quantify and probability. The result analysis are compared with filed data and in express of probability, it can extend to discuss uncertainty in dam removal for better decision making.中文摘要 i

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
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
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
