    Full text link
    Smart Door Locks System Based on Internet of Things Concept with Mobile Backend as s Service is the smart door locks development are supported by cloud computing technology as data storage. Methods of development that exist in this system is to combine technology (1) ESP8266 (2) Firebase and (3) Android Apps. Firebase is one of cloud-based services that are used to store data online. ESP8266 able to communicate with firebase well to process the read and write data directly using internet communication channels. Android application used to direct communication to the firebase for monitoring and  controlling simultaneously to the system. Android app can control / monitoring Indirectly to ESP8266 module via Firebase that serves as a mobile Backend as a Service to apply the rules of the Internet of Thing

    Pelacakan Benda Bergerak Menggunakan Metode Mean-Shift dengan Perubahan Skala dan Orientasi

    Full text link
    Pelacakan benda bergerak atau object tracking merupakan suatu proses mengikuti posisi obyek di dalam suatu citra. Algoritma mean-shift adalah salah satu algoritma pelacakan obyek yang sering digunakan dalam proses pelacakan obyek. Algoritma mean-shift merupakan algoritma non-parametric yang efektif dan cepat akan tetapi belum mampu untuk mengikuti sebuah obyek yang mengalami perubahan ukuran dan perubahan orientasi. Pada penelitian ini dilakukan pengembangan metode mean-shift klasik yang mampu menangani pelacakan obyek yang mengalami perubahan skala dan orientasi. Dengan bobot gambar yang berasal dari target obyek dan target kandidat obyek dapat merepresentasikan kemungkinan wilayah tersebut merupakan target obyek. Pelacakan obyek menggunakan algoritma mean-shift menggunakan momen orde ke nol dan ke satu dari bobot gambar. Dengan momen orde ke nol dan koefisien Bhattacharyya antara target model dengan target kandidat model dapat digunakan untuk menentukan perubahan ukuran dan orientasi obyek target.Hasil pengujian menunjukkan tingkat keberhasilan obyek tracking dari beberapa sample video di dapatkan. Dari hasil pengujian sistem Untuk parameter input dengan increment area 5 hasil yang di dapatkan adalah 61,53% berhasil, 15,38% berhasil sebagian. Dan 23,07% gagal. Sedangkan untu parameter input dengan increment 10 hasil yang di dapatkan adalah 76,92% berhasil, 7,69% berhasil sebagian dan 23,07% gagal. Tingkat keberhasilan dalam mengenali obyek target menjadi meningkat ketika parameter input increment area dinaikkan akan tetapi terjadi penambahan waktu pelacakan. Semakin besar wilayah target obyek yang dilacak maka waktu yang dibutuhkan untuk pelacakan juga semakin bertambah

    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

    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
