"This book is dedicated to the analysis of parametric amplification with special emphasis on the MOS discrete-time implementation. This implementation is demonstrated by the presentation of several circuits where the MOS parametric amplifier cell is used, small gain amplifier, comparator with embedded pre-amplification, discrete-time mixer/IIR-Filter, and analog-to-digital converter (ADC). Experimental results are shown to validate the overall design technique."

"This volume, the content of the first conference of the European Society for Mathematics and the Arts (ESMA), held in Paris in 2010, gives an overview on some significant and beautiful recent works where maths and art, including architecture and music, are interwoven. The book includes a wealth of mathematical illustrations from several basic mathematical fields including classical geometry, topology, differential geometry, dynamical systems. Here, artists and mathematicians alike elucidate the thought processes and the tools used to create their work."

"The first edition of Visualization in medicine and life sciences (VMLS) emerged from a workshop convened to explore the significant data visualization challenges created by emerging technologies in the life sciences. The workshop and the book addressed questions of whether medical data visualization approaches can be devised or improved to meet these challenges, with the promise of ultimately being adopted by medical experts. Visualization in Medicine and Life Sciences II follows the second international VMLS workshop, held in Bremerhaven, Germany, in July 2009. Internationally renowned experts from the visualization and driving application areas came together for this second workshop. The book presents peer-reviewed research and survey papers which document and discuss the progress made, explore new approaches to data visualization, and assess new challenges and research directions."

"[Teknologi robot yang berkembang pesat sekarang ini menyebabkan naiknya kebutuhan akan teknik pengolahan citra dan teknik memprediksi gerak objek. Salah satu cara yang paling umum dalam mendeteksi suatu benda adalah dengan menggunakan filter warna dan sensor untuk mendeteksi jarak. Namun, kelemahan metode tersebut terletak pada rentannya filter warna terhadap gangguan luar, serta lambatnya sensor dalam mengukur jarak. Dalam penelitian ini, digunakan sebuah Kalman Filter yang berfungsi untuk mengurangi efek gangguan dalam filter warna, serta membuat program tetap dapat memprediksi lokasi bola ketika bola hilang dari pandangan. Sebuah algoritma yang dapat memprediksi jarak dan koordinat bola tanpa menggunakan sensor juga dikembangkan demi mempercepat waktu proses. Setelah lokasi bola diketahui, sebuah algoritma untuk memprediksi koordinat jatuh bola juga dikembangkan. Koordinat jatuh ini nantinya dapat dimasukkan ke sistem penggerak robot yang mampu mengarahkan robot ke lokasi jatuhnya benda.

, Image processing and trajectory prediction play an important role in today’s

robotic technology and its applications are limitless. The most common method of

detecting an object is through the use of colour filter and a sensor to measure its

distance. However, most of the time, colour filter is very vulnerable to noise and

the robot would consume a huge chunk of processing time using distance sensor.

In this paper, a Kalman Filter is developed base on a constant velocity model.

This Kalman Filter will provide a better estimator on the object’s position and

estimate the position of the object when there are occlusions. In addition to the

Kalman Filter, a novel sensorless approach to measure an object’s distance is also

developed in order to improve processing time. After the coordinates of the object

are obtained, an algorithm that could predict its landing coordinates is also

developed by using MATLAB. This landing coordinates could then be fed into a

motor system in a robot which will then move towards the predicted coordinates.]"

"Sampah elektronik atau e-waste merupakan peralatan listrik dan elektronik yang sudah tidak digunakan lagi dan dianggap sebagai sampah oleh pengguna. E-waste terdiri dari logam dan plastik, beberapa bahan yang termasuk kategori berbahaya, tidak dapat terurai secara alami, dan pengelolaan yang salah pada e-waste dapat membahayakan lingkungan serta kesehatan manusia. Logam yang terkandung dalam limbah elektronik dapat dipulihkan dan didaur ulang untuk penggunaan lebih lanjut serta memiliki nilai ekonomis. Metode pemulihan dengan pemisahan berbasis konduktivitas listrik yaitu pemisahan berbasis arus eddy, interaksi antara medan magnet alternatif dan arus eddy yang diinduksi oleh medan magnet drum yang berputar dibungkus dengan magnet permanen menghasilkan gaya tolak (gaya Lorentz) pada logam dan memisahkan logam, namun ada proses pemisahan yang tidak akurat. Penelitian skripsi ini bertujuan untuk mengetahui gaya Lorentz yang akan dihasilkan pada kondisi logam tertentu untuk memaksimalkan laju pemisahan pemisah limbah elektronik berbasis arus eddy menggunakan perangkat image processing.

Electronic waste or e-waste is an electrical and electronic equipment that is not used anymore and regarded as waste by the user. E-waste consist of precious metals and plastic some of the materials considered as hazardous category, it cannot decompose naturally, and mistreatment of e-waste can harm environment and human health. The precious metals contained in e-waste can be recovered and recycled for further use and economical value. The method of recovery is by electric conductivity-based separation, namely eddy current-based separation, interaction between alternative magnetic field and eddy current induces by the magnetic field of a rotating drum wrapped with permanent magnet generates a repulsive force (Lorentz force) on the metal and separates the metal, however there is an inaccurate separation process. This undergraduate thesis research is to investigate the Lorentz force that will be generated in certain scrap metal conditions in order to maximize the separation rate of eddy current-based electronic waste separator using image processing software.

"ABSTRAKSaat ini, pengukuran dimensi zona inhibisi masih menggunakan alat pengukur manual seperti penggaris atau jangka sorong. Kini dengan perkembangan teknologi memungkinkan pengukuran dilakukan dengan berbasis kamera digital dan pengolahan citra. Adanya perangkat penunjang lain seperti sumber cahaya, dapat menyebabkan posisi kamera tidak tegak lurus terhadap objek pengukuran. Pada penelitian ini diperkenalkan sistem koreksi tilting pada pengukuran zona inhibisi berbasis kamera.

ABSTRAKCurrently, the measurements of the Zone of Inhibition are still using manual measurement tools such as a ruler or caliper. Now with the development of technology enables this measurement based on digital cameras and image processing. The presence of another supporting devices such as light sources, causing the camera position not perpendicular to the object. This study introduces the tilt correction system on camera-based measurement of the inhibition zones, which consists of hardware (measuring instruments and cameras) and software. Image processing techniques such as geometrical transformations, edge detection, and line detection is used to build the automated tilt correction system. The experiments have been conducted using standard checkerboard calibrator objects and Zone of Inhibition objects at various orientations and the angle of rotation of the object. In general, based on experiment results, the system has been successfully implemented for not perpendicular dimensional measurements of zone of inhibition. Tilt correction system improves the measurement system performance with a reduction in estimated errors up to 39,6%. The maximum angle with a tolerance level that is acceptable is 40°."
