RANCANG BANGUN SEPEDA LISTRIK UNTUK PENDERITA CACAT KAKI
Get PDFThis time the need of transport's mode for the disabled leg is not maximized. To fulfill these need, we need the necessary transportation tools, one of the tools is a bike. However, the existing bike cannot be used for patients with leg disabilities. The purpose of this research is to design an electric bike wake for the disabled leg with movers using hand paddles and electric system. Bikes are made to be able to provide a low risk of injury while driving and can be used on any terrain. This research will be focused on the design and make electric bike frame for the disabled leg with brushless motor drive and battery charging via PLN's electricity. The stages of the research is the first stage of drafting the bike according to the list of needs. The concept design electric bikes are made with size 1270 x 850 x 1226 mm and uses three wheels. For the movers using brushless DC motors 350 Watt / 48 V with battery accu used 12V / 7 Ah combined series of 4 pieces battery and for manual use paddle power hand. The second stage of is the process of making electric bike. The third stage of is the process of testing an electric bike. Tests performed include testing the strength of the frame, tilt test and movers’s test on the bike. From the results of Static test performed that by loading 70 kg on the bike showed the bike suffered no damage and passed the test. In testing of stability with position of the front wheel facing upwards, downwards and sideways with make a tilt angle of 100. The test results revealed bike was not damaged and will not tip so the bike passed the test. For the test movers electric bike, the speed of electric bicycles from testing up to 20Km / h on a straight road for 1 hour and charging time for 3.5 hours using a charge battery 48V / 2A through voltage PLN’s source.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
RANCANG BANGUN MESIN MESIN PENCETAK BERAS ANALOG SEBAGAI PANGAN LOKAL DAERAH BANGKA
Get PDFBeras analog yang dikenal juga beras aruk merupakan pangan lokal dari daerah Bangka yang perlu dipertahankan dan dilestarikan. Bahan dasar beras analog atau beras aruk ini terbuat dari ubi kayu. Pemanfaatan beras analog ini sebagai bahan baku yang dapat diolah menjadi produk lain seperti kue, nasi goreng dan aneka pangan lainnya. Proses produksi beras analog mempunyai beberapa tahapan diantaranya perendaman, pengadukan dan penghancuran serat ubi kayu, pemerasan tepung beras, penumbukan, pencetakan, penyangraian dan penjemuran. Salah satu mesin yang perlu dikembangkan adalah mesin pencetakan beras yang selama ini dilakukan secara manual. Mesin ini bertujuan agar dapat mengaduk, menumbuk dan membentuk sekaligus secara kontinyu. Sistem kerja mesin adalah adonan dimasukkan ke dalam wadah extruder. Selama dalam wadah ini extruder adonan dipanaskan dengan pengaruh heater sehingga adonan benar-benar tercampur merata, dapat lebih halus dan seragam. Kemudian adonan terdorong keluar dan dibentuk menyerupai beras dan butiran beras analog. Metode pelaksanaan dalam penelitian ini yaitu pengumpulan data, pembuatan konsep dan rancangan, pembuatan dan perakitan mesin, uji coba dan analisa hasil. Hasil uji coba mesin adalah didapatkan adalah bentuk beras analog yang seragam dengan kapasitas mesin 25 kg/jam
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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 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
