Kontrol Logika Fuzzy untuk Pengisian Baterai Metode Constant Voltage Menggunakan SEPIC Converter
Full text linkEnergi Surya merupakan sumber energi yang saat ini dapat dimanfaatkan untuk membangkitkan energi listrik. Penggunaan energi matahari di Indonesia dapat didukung dengan letak Indonesia yang merupakan negara beriklim tropis sehingga selalu disinari matahari setiap tahunnya. Perubahan energi matahari menjadi energi listrik memerlukan panel surya sehingga sinar matahari dapat diubah menjadi energi listrik yang dapat digunakan. Pada sistem charging proyek akhir ini memanfaatkan sumber dari sinar matahari yang akan menghasilkan energi listrik dengan panel surya. Dengan tegangan output 14.4V dan arus output 16A untuk charging baterai lead acid 12V/100Ah dengan tegangan input 18V dari panel surya yang akan diturunkan menggunakan sepic coverter. Baterai lead acid 12V/100Ah ini digunakan untuk mensuplai beban rumah DC yang meliputi 6 buah lampu DC masing-masing 10Watt, 2 buah kipan angin DC masing-masing 12Watt dan 1 biah pompa air DC 60 Watt. Sistem charging menggunakan metode constant voltage dengan kontrol fuzzy logic controller. Pada hasil pengujian close loop tegangan keluaran dari SEPIC converter untuk pengisian baterai yaitu antara 14,52Volt sampai 14,35Volt pada irradiasi antara 1000W/m2 sampai 600W/m2 dengan rata-rata error tegangan keluaran SEPIC converter dengan tegangan set point yaitu sebesar 0,43%
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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 linkWe 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
Peran Pemerintah dalam Program Pembangunan Desa Wonosari Kecamatan Tutur Kabupaten Pasuruan: The Role of the Government in the Wonosari Village Development Program, Tutur District, Pasuruan Regency
No full textThis study aims to describe the role of government in building of Wonosari village, Tutur sub district, Pasuruan regency and how the implementation program of the building of Wonosari village. This study uses qualitative descriptive. The informants of this study are head of department, head of compiling program, head and members of local gov- ernment, BPD and societies. Collecting data technique doing by triangulation, inductive data analysis, and the result of the qualitative study emphasize to the good meaning of the study. this study showed that the role of government in building of Wonosari village is good enough and balance. The cooperation is mutual where the involved knowing each the position and role in build the village. The local government has role to facilitate the societies and give good guidance about the purpose of the building. People play the role in giving the ideas, energy and wealth to the success of build. Whereas, the support fac- tor is cooperation of government – society is the approach of government to the society. And the society has understood about their position and their role in study. In addition to, the inhibit factor is minimal awareness of society to the program and there is still opinion from the government that society is the object of supervision build
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
