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
PELATIHAN SERVIS RINGAN KENDARAAN SEPEDA MOTOR BAGI MASYARAKAT DESA RIDOGALIH
Get PDFMotorbikes are a means of transportation that is often used in daily activities, the development of increasingly sophisticated technology has begun to be combined with the help of electronic control circuits such as injection systems to control combustion in the motorcycle combustion chamber or indicators to show hot engine temperatures that make it easier for motorcycle owners to carry out vehicle maintenance. Therefore, due to the lack of workshops or vehicle service services, here the author will share information about motorcycle maintenance that can be done by yourself to save costs and can be developed as a form of business, such as a workshop. With this lack of information, most people only use motorbikes for their daily needs and ignore motorcycle maintenance. Here the author will educate the community on how to maintain their two-wheeled vehicles in Citeureup 1 hamlet by socializing the importance of maintaining two-wheeled vehicles, training on maintaining two-wheeled vehicles, and evaluation to ensure that the community can maintain their own motorbikes. This program also has the aim that the people of Sirnajaya Village, Serang Baru District, Bekasi Regency are able to maintain their own motorbikes and can be developed as a form of business, namely a workshop. Based on the light service training, there are several impacts, among others can increase understanding related to light service procedures such as engine oil change, axle oil, CVT maintenance and replacement of front brake lining and understand about safety riding and have understood how to drive properly
PLCMIKRO SEBAGAI SOLUSI OTOMATISASI INDUSTRI
Get PDFPLC has several advantages including the industry can control the equipment along with the complexity of the sensor device is quite high, thus easing the work of man. PLCMIKRO is designed to use the language ladder (stairs) and use a PIC16F877A microcontroller type as the central processing unit, for the detection sensor is used as an isolation voltage optocoupler with devices outside the microcontroller and the output is used to load its driver transistor relay circuit. PLCMIKRO can communicate with a computer using RS-232 serial communication. PLCMIKRO work after receiving a command in a file after a compiled using software Hexadesimal LDMIKRO and compile the results sent to the microcontroller using software WinPicPgm via RS-232 communication channel

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
PERANCANGAN DAN REDESAIN SISTEM PENGENDALIAN TEKANAN PADA GAS METERING STATION MENGGUNAKAN METODE NEURO FUZZY
Get PDFGas Metering Station terletak diluar pabrik (out site). Pengontrol ini berupa serangkaian katup disertai piranti tambahan yang diharuskan mampu menjaga tekanan supplay gas dari Pertamina dalam batas yang diharapkan yaitu 25kg/cm2. .Jenis controller yang tersedia dipasaran kebanyakan bertype Proportional Integrator & Diagram (PID). Namun perkembangan saat ini muncul controller yang menggunakan neuro Fuzzy (ANFIS). Perancangan dilakukan dengan pengendali neuro-fuzzy,yang menggabungkan kemampuan belajar Neural Network dengan kemampuan pengambilan keputusan pada neuro-fuzzy. Dari hasil simulasi dengan Simulink pada Matlab versi7.7 didapat kinerja Neuro fuzzy menunjukkan settling time pada detik ke 8, respon sistem dijaga pada keluaran sekitar 25 kg/cm2 atau sesuai dengan nilai setpoint yang dikendalikan dan tidak terjadi overshoot. Pada uji noise/gangguan pengendali neuro-fuzzy menunjukkan performansi yang lebih baik dengan waktu penetan 17 detik .Dari segi safety, pengendali Neuro Fuzzy bisa dikatakan lebih aman, karena tingkat toleransi error yang lebih kecil bila dibandingkan dengan pengendali PID. Penelitian yang akan datang diharapkan membandingkan PID dengan Neuro dari segi ekonomis dengan cara merakitnya dalam bentuk komponen riil
