    PERANCANGAN TOPOLOGI DINAMIS SECARA ACAK DALAM MOBILE AD- HOC NETWORK DENGAN PENDEKATAN PEMODELAN

    ABSTRAK Mobile Ad-hoc Network (MANET) sebagai wireless local area network yang bersifat dinamis dalam hal pergerakan node berperan untuk mengkondisikan setiap terminal client sebagai backwarding/fowarding-devices. Dengan demikian kondisi topologi jaringan akan berubah seiring dengan perubahan posisi pada node-client. Hal ini tentu saja akan memberikan keuntungan yang baik pada client dalam segi fleksibilitas tempat, mengurangi biaya instalasi, reduksi penyediaan infrastruktur dan sifat temporary instalasi sesuai dengan kebutuhan yang diinginkan. Pada penelitian ini telah dilakukan pemodelan dan simulasi untuk menunjukkan algoritma routing-network, status node yang terlibat dalam MANET, dan perhitungan nilai QoS dari komunikasi-data yang dibangun antar node yang saling bertetangga. Hasilnya menunjukkan perubahan topologi jaringan mengalami perubahan seiring dengan perubahan skenario yang dibangkitkan secara random dan stokastik; dan perubahan topologi jaringan ini merepresentasikan perubahan posisi node dalam MANET saat membangun komunikasi-data dari node-sender ke node-receiver. Metode pengujian menggunakan teknik kuantitatif serta kondisi random direpresentasikan dengan pembangkitan bilangan random yang bekerja berdasar Distribusi Normal/Gauss. Algoritma SNetS yang digunakan telah dapat mengakomodir jumlah N-node, sehingga kondisi node-terminal, bagaimana status node, serta QoS yang didapatkan mendekati kondisi real.

    Dynamics System Modeling Approach in Node Mobility on Mobile Ad-hoc Network

    Full text link
    Movement of the nodes in a mobile ad-hoc network is affected by distance and strong transmit / receive signal between neighboring nodes to each other, so how the mobility of the nodes in the network connection can maintain connectivity in the line-of-sight is emerging challenges in the dynamics system. In mobile ad-hoc network each connection connectivity is temporary, so the topology changes that appear along with the mobility of the nodes in constructing communication calls will change the position of the transmitter and receiver. This research has been done on modeling the dynamics system approach for each node mobility scenarios were created based on the selected tests and determined. With quantitative methods used involve tools that can observe the data streaming process in real-time, the results obtained demonstrate the system dynamics can serve to test the mobility of the nodes that occur in mobile ad-hoc network is able to maintain a connection connectivity between each neighboring node

    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

    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
