Dynamic Data Collect Algorithm with Bluetooth Low Energy and Internet of Things
近年來物聯網概念開始興盛,任何裝置都可以當成感測器節點,並透過無線網路傳送資料進行監測。目前物聯網最需要解決的問題便是省電與資料收集的問題,其中藍牙4.0低功耗的推出,使得藍牙裝置的使用時間單位從小時變成天數。其中並不是每個節點都具有連線到網際網路的能力或是剛好在有網路連線能力的節點範圍內,必須透過其他的節點進行轉傳,所以我們需要找到一條合適的路徑傳送到收集點。 本次的研究針對自行車當作資料感測及收集節點並用藍芽低功耗當作網路傳輸協定來提出路徑建立方法。主要針對兩個問題去做演算法的設計。 第一是在使用藍芽低功耗當作網路傳輸時如何利用較少長度的廣播封包來建立起傳輸路徑並針對連線被占用的情形去做改善來提升傳送成功率。 第二是在我們的環境中是利用停在停車場的腳踏車做節點來收集資料,在這種情形下腳踏車有可能會隨意地離去或加入,在這種動態環境下如何去減少反應時間。 在本論文中,我們會探討網路拓墣的建立及傳輸路徑選擇演算法,並透過模擬驗證我們提出的演算法有較好的傳輸效能。Recently IoT(Internet of Things) is the most popular topic in the world. It shows that everything can be a sensor node, and send the data from wireless network. Many issues related to this topic need to be solved such as the power consumption problem and how to collect the data. The Bluetooth 4.0 Low Energy let the device activity time from hours to days. The problem with data collection is that sensor nodes may not have Internet connecting ability or in the connection range of node which has Internet connecting ability(sink node). Those nodes may need some other node to relay the data to the sink node. So we should use the routing method to find a suitable path. In this research we focus on the transportation like bicycle which is placed in the parking space and use Bluetooth Low Energy as the communications protocol. Our algorithm design is based on two main purpose, one is to use the short length broadcast packet to construct route and reduce the network congestion. Another is that bicycle may leave or enter randomly, so we should have lower response time when bicycle leaved in the dynamic environment. In this thesis we will study on the network topology construct strategy and transmission route algorithm. We also use simulations to prove that we have the better transmission efficiency
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

Author Under Sail The Imagination of Jack London, 1893-1902
In 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.
