No full textABSTRAK
Mata adalah salah satu organ tubuh manusia yang sangat penting. Mata berfungsi mengenali pertama kali berbagai benda yang kita temui dengan melihatnya. Namun tidak semua orang bisa menggnakan fungsi mata secara sempurna. Beberapa orang tidak bisa menggunakan mata sebagaimana fungsinya. Hal ini salah satunya disebabkan oleh kebutaan. Berdasarkan latar belakang tersebut penelitian dilakukan dengan tujuan untuk: (1) Untuk menghasilkan alat yang dapat mendeteksi keberadaan benda di depan penderita tunanetra dengan output suara berbasis mikrokontroler, dan (2) Untuk menghasilkan alat penunjuk arah mata angin bagi penderita tunanetra dengan output suara berbasis mikrokontroler.
Perancangan alat ini memanfaatkan teori tentang mata angin dan kecepatan gelombang bunyi di udara. Perancangan dan penelitian ini dilakukan di Laboratorium Elektronika Riset UIN Maliki Malang pada tanggal 1 November
2009 sampai 30 Maret 2010. Perancangan ini melalui dua tahap, yaitu tahap perancangan hardware dan software. Hardware yang digunakan dalam perancangan alat ini adalah kompas digital HM55B untuk menentukan arah mata angin, sensor Ultrasonik D-Sonar untuk mengukur jarak pengguna dengan benda di depannya, mikrokontroler AT89S51 sebagai memori program, dan ISD 2590 sebagai perekam suara untuk output. Software pada alat ini menggunakan bahasa pemrograman Assembler.
Data yang diperoleh dari penelitian ini dianalisis dan dicari simpangannya. Pada perangkat penunjuk arah HM55B diperoleh simpangan rata-rata sebesar 3,65% dengan taraf ketelitian 96,35% dan pada perangkat pendeteksi jarak benda kesalahan relatifnya sebesar 1,92% dengan taraf ketelitan 98,08%. Hasil penelitian ini menunjukkan bahwa alat tersebut dapat bekerja dengan baik.
ABSTRACT
The eyes are one of the important organ of human being. The eyes are the first human organ that recognize the various objects we meet with to see it. But not everyone can make eyes function perfectly. Some people can not use the eyes as its function. One of the caus is blindness. Based on this research background the aims of this research are in order: (1) To produce a tool that can detect the distance of objects in front of visually impaired patients with microcontroller- based on voice output, and (2) To produce a cardinal direction pointing device for visually impaired patients with microcontroller-based on voice output .
The design of this tool uses the cardinal of theories and wave speed of sound in air. The process of designing and researching was conducted in the Electronics Research Laboratory Maliki of UIN Malang on November 1, 2009 until March 30, 2010. This design through two stages of hardware and software design. The hardware was used in design this tool is a HM55B digital compass to determine direction cardinal, D-Sonar Ultrasonic sensor to measure the distance the user with the objects in front of him, as the AT89S51 microcontroller program memory, and the ISD in 2590 as a voice recorder for output. The software on this device using Assembler programming language.
The data obtained from this study were analyzed and searched its deviation. At the direction of a pointing device HM55B obtained an average deviation of 3,65% with 96,35 of accurate rank and the detection distance for an object relative error of 1,92% with 98,08 of accurate rank. This study has shown that these tools can work well in accordance with the design

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
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
