Abstract. The license plate recognition usually used as part of system such as parking system. License plate detection considered as the most important step in the license plate recognition system. We propose methods that can be used to detect the vehicle plate on mobile phone. In this paper, we used Sliding Window, Histogram of Oriented Gradient (HOG), and Support Vector Machines (SVM) method to license plate detection so it will increase the detection level even though the image is not in a good quality. The image proceed by Sliding Window method in order to find plate position. Feature extraction in every window movement had been done by HOG and SVM method. Good result had shown in this research, which is 96% of accuracy.
In general, induction motors can be operated by connecting the motor directly to the supply circuit or by using a voltage that has been reduced to the motor during the start period. The obstacle of using a 3 phase induction motor is when starting, where the motor requires more current, which is about 5 to 7 times the nominal current, causing the voltage on the system to drop which can interfere with other equipment. In this study the researchers analysed the starting of a 3 phase induction motor using the direct on line system (DOL), star delta, and variable speed drive (VSD) both when the motor is free of charge and when the motor is loaded. Through this research can be seen the difference in the magnitude of current, voltage, power and THD. From the results of observations on the three types of 3 phase induction motor starting methods, it was shown that using a variable speed drive (VSD) altivar61 gave the largest decrease in current when compared to other systems.
Teknologi digital sudah banyak sekali dimanfaatkan di berbagai bidang, baik terasa maupun tidak terasa. Digitalisasi adalah proses alih media dari bentuk tercetak, audio, dan video menjadi bentuk digital. Demikian juga pada digitalisasi dokumen laboratorium (lab) yang merupakan sistem yang dikembangkan menggunakan pendekatan berdasarkan penggunaan teknologi digital yang terintegrasi dengan sistem mekanisasi pengolahan data sebagai penyedia informasi untuk mendukung kegiatan yang berkaitan dengan administrasi dan operasional lab. Untuk menjalankan proses digitalisasi ini memerlukan perangkat lunak berupa pengolahan file menjadi bentuk digital yaitu omnipage software. Setiap lab memiliki sistem untuk menyimpan data yang berhubungan dengan peralatan dan administrasi lab. Selama ini hal tersebut masih dilakukan secara manual, yang dapat menghabiskan waktu lama dan kemungkinan menyebabkan kesalahan dalam proses pencatatan data. Proses digitalisasi dokumen laboratorium ini terdiri atas seleksi documen, persiapan alat dan bahan, instalasi jaringan, instalasi system digital, pelatihan digitalisasi kepada tim, scanning dokumen, dokumentasi perlengkapan laboratorium, media transfer (microfilm ke digital), menterjemah dan membuat panduan penggunaan alat yang berbahasa Inggris, membuat analysis dan validasi data, mengedit file digital, input dan meng-upload data, memberikan label/kode pada peralatan, dan membuat back up data. Dengan pemanfaatan omnipage software pada proses digitalisasi ini memberikan hasil digitalisasi yang lebih efisien dalam kapasitas dan kualitasnya.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
