ABSTRAK
Kursi roda merupakan salah satu alat bantu gerak berupa perangkat medis
dan sarana bagi manusia (pasien) berkebutuhan khusus yang dapat membantu
menjalankan aktivitasnya akibat adanya gangguan saraf motorik pada kakinya.
Pada umumnya kursi roda masih membutuhkan orang lain untuk mendorongnya.
Penulis mencoba memodifikasi dengan menambahkan motor DC elektrik sebagai
penggerak utama. Dengan adanya inovasi dari kursi roda elektrik ini diharapkan
dapat membantu para penderita untuk beraktifitas dengan rasa aman tanpa
mengandalkan bantuan orang lain dalam menjalankan kursi rodanya.\ud
Pada makalah ini telah direalisasikan suatu sistem kendali kecepatan pada
kursi roda elektrik yang telah menerapkan metode kendali PID, dalam
pengoperasian kursi roda ini menggunakan modul joystick dual-axis untuk
memberi perintah ke arah maju, mundur, dan berbelok. Untuk menggerakkan
motor menggunakan metode PWM (Pulse Width Modulation), mikrokontroller
yang digunakan adalah Arduino Uno R3 yang berfungsi sebagai pengolah data
utama, sensor rotary encoder digunakan sebagai timbal balik (feedback) pada
output motor.
Hasil pengujian pada kecepatan putaran kedua roda menunjukkan bahwa
pengontrol yang digunakan adalah pengontrol P,I, dan, D dengan parameter pada
kedua motor (Kp=10.5, Ki=2.5, Kd=4). Kecepatan kursi roda maksimum 18 rpm
dengan waktu naik selama 13 detik. Namun pada realisasinya kursi roda elektrik
tidak berjalan dengan baik dikarenakan beratnya bagian mekanik.

ABSTRACT
Wheelchair is one of the tools of motion in the form of medical devices
and facilities for human (patients) with special needs that can help run its
activities due to motor neurological disorders in his legs. Generally wheelchairs
still need others to push it. The author tries to modify it by adding an electric DC
motor as the prime mover. With the innovation of electric wheelchair is expected
to help the patient to activities with a sense of security without relying on the help
of others in running the wheelchair.
In this paper we have realized a speed control system in an electric
wheelchair that has applied PID control method, in this wheelchair operation
using dual-axis joystick module to command forward, backward and turn. To
drive the motor using PWM (Pulse Width Modulation) method, the micro
controller used is Arduino Uno R3 which serves as the main data processor, rotary
encoder sensor is used as feedback on the motor output.
Test results at rotation speed of both wheels indicate that the controller
used is controller P, I, and D with parameters on both motors (Kp = 10.5, Ki =
2.5, Kd = 4). Maximum wheelchair speed is 18 rpm with up time of 13 seconds.
But in realization the electric wheelchair is not running well due to the weight of
mechanical parts.

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
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
