    No full text
    It is a new and open-source benchmark for multiprocessor based embedded system. It comprises a set of parallel implementations for seven classical algorithms that cover different computing features of general-purpose processor. The performance data including tables and figures is provided for guiding the potential users to evaluate the design of multiprocessor based embedded system. The parallel implementations for seven applications that cover four categories are shown according to the category: Automation and Industry Control * Bitcount * SUSAN * BASICMATH Network * Patricia * Dijkstra Office * Stringsearch Security * SHA Among them, Bitcount and Dijkstra involve more than one parallel application implemented for different functions or using different strategies. Bitcount consists three parallel applications, parallel Bitcnt_1, parallel Bitstring and parallel Bitcnts, that implemented bit counting with different strategy. Three parallel applications implemented for Dijkstra. One is for all-pairs shortest paths problem. Another two are for solving single-source shortest paths problem using single queue strategy and multiple queue strategy respectively. Stringsearch consists of Pratt-Boyer-Moore, Case-sensitive Boyer-Moore-Horspool, Case-Insensitive Boyer-Moore-Horspool, and Boyer-Moore-Horspool (Case-insensitive with accented character translation) implementations. Source code of sequential versions of these applications download from Mibench as well as the standard output based on x86-linux. For OpenMPBench, all parallel applications have been implemented in ANCI C language using POSIX threads. All libraries related to implementations are based on GNU standard library. Development environment is in UBUNTU 9.04 with 2.6.28-generic Linux kernel, GCC 4.2.4 compiler, and Emacs 22.1 editor. On the basis of current hardware condition, a workstation with 8 processors, shipped with UBUNTU 4.2.4, is selected for experiment environment. UBUNTU is a free GNU Linux version that offers all GNU standard library and GCC has been installed by default. In conclusion, we consider this experiment environment is available to simulate the multiprocessor based on embedded systems.Det är en ny och öppen källkod riktmärke för multiprocessor baserade inbyggda system.

För OpenMPBench har alla parallella ansökningar har genomförts i ANCI C-språk med POSIX trådar. Alla bibliotek i samband med implementationer är baserat på GNU standard bibliotek. Utvecklingsmiljö i Ubuntu 9.04 med 2.6.28-generic Linuxkärnan, GCC 4.2.4 kompilator och Emacs 22,1 redaktör. På grundval av nuvarande hårdvara skick, en arbetsstation med 8 processorer, som levereras med Ubuntu 4.2.4, har valts för experiment miljön. Ubuntu är ett gratis GNU Linux-version som kan erbjuda alla GNU Standard bibliotek och GCC har installerats som standard. Sammanfattningsvis anser vi att detta experiment miljön är tillgänglig för att simulera multiprocessor baserade på inbyggda system.Yuchen Liang: phone no: 8641182120823 6-3-1, No. 44, Huabei Road Ganduan, Ganjingzi District, Dalian City, 116023, Liaoning Province, P.

    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

    Full text link
    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

    Full text link
    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

    No full text
    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

    No full text
    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.
