This paper studies on the application of X-ray irradiation from synchrotron light for burnishing head patterning. Feasibility study of SU-8 negative photoresist for AlTiC hard mask in reactive ion etching in CF4 plasma is investigated and compared with chromium and AZ photoresist. X-ray lithography is used to make SU-8 hard mask on AlTiC substrate, while chromium and AZ hard mask are fabricated by UV lithography. The selectivity ratios between the etching rate of AlTiC and hard mask are investigated to estimate the sufficient mask thickness in the standard AlTiC etch depth of 30 μm. The SU-8 selectivity ratio of 4.46 is enough to create the burnishing head pattern with critical dimension error of 0.86% and the standard deviation of 0.065. Experimental results confirm that SU-8 photoresist is suitable if the process requires another material (non metallic) to decrease manufacturing cost and processing time.

In this paper, digital image analysis is applied for non-destructive classification of rice and sticky rice seeds that are mixed together. It is a difficult task because of the similar surface color of the seeds. This paper presents an automatic classification method based on RGB color features. Hardware of image capturing is designed using back light source in order to maximize the contrast between the rice seeds and their background. RGB histogram is then calculated. The rule of classification between rice seed and sticky rice seed are created. Almost 97% of rice seeds are identified correctly. The correct classification rates for two rice varieties are: rice seeds `Jasmine' 96.34% and sticky rice seeds 100%.

An ultra-wideband (UWB) pulse generator circuit is said to be the heart of any UWB system. However, the pulse generator typically requires an edge-triggered driver that is the essential signal source of any pulse generator. The design of edge-triggered driver circuit influences the amplitude, the pulse repetition, and the width of UWB pulses at the output. In this study, a low cost and low complexity edge-triggered driver circuit is proposed, which creates a square wave with very short rising and falling edges to feed a step recovery diode based pulse generator with cascode pulse shaping circuit. The proposed driver circuit is tuneable by simply changing the crystal oscillator component in the circuit, which results in different pulse repetition frequency for the UWB pulse generator. The measurement results when changing the crystal oscillator from 1MHz to 8MHz showed that the output UWB pulse was a Gaussian pulse with pulse width of 1.87 ns and pulse amplitude of 2.16 Vp.

This paper describes the design and realization of a process and temperature compensated CMOS ring oscillator. The proposed circuit employs a current-starved ring oscillator with a compensated bias circuit, which generates an adaptive control voltage to maintain a fixed oscillation frequency against temperature and process variations. Simulation results using process parameters from a 0.18-μm CMOS technology and 1.8-V power supply voltage showed that the worst-case frequency variation of 4.49% and 2.29% could be obtained at the oscillation frequencies of 100 MHz and 150 MHz, respectively, over the temperature range of - 40°C to 125°C. The overall circuit consumes 437μW at 100MHz and 537μW at 150MHz.

This paper presents the application of fuzzy logic controller for series active power filter to control the compensating voltage. The instantaneous power theory is used to calculate the reference voltages for harmonic voltage mitigation. The control strategy and the concept of fuzzy logic controller are described in the paper. The Mamdani max-min and the mean of maximum approach are used for the fuzzy inference and the defuzzification method, respectively. The simulation results show that the fuzzy logic controller can control the compensating voltages to achieve the %THD of the source voltages at the point of common coupling under an acceptable range following on the IEEE Std. 519-1992.

We propose a new design of most important logical circuits using optical devices for all-optical addition/subtraction applications, in which the simultaneous operation of addition/subtraction arithmetic operation can be performed by using the dark-bright soliton conversion control. In operation, all-optical data input for addition/subtraction of binary operation logic `0' and `1' are formed by dark soliton (D) and bright soliton (B) pulses, respectively. By using the dark-bright soliton conversion behavior, the conversion between dark and bright soliton pulses can be obtained and form the logic pulses by a π/2 phase shifted device (i.e. an optical coupler), in which the binary operation can be formed simultaneously at the through and drop ports, respectively. In application, the proposed scheme can be recognized as a simple and flexible system for forming the logic switching system, which can be used for advanced logical system.

When modulated with a continuous signal, the intensity of light emitted by a Light Emitting Diode needs to be adjusted such that linearity is maintained between the modulating voltage and the intensity of the emitted light. This paper presents a low-cost solution that is able to maintain linearity over virtually the entire intensity range. Extending the range of linearity is accomplished by incorporating a feedback loop that compensates for the non-linear parameters of the circuit's active components, including the LED. The technique is applied to convert a commercially available LED spotlight into a device that allows for the transmission of continuous Visible Light Communication schemes.

Modern speech recognition techniques rely on large amount of speech data whose acoustic characteristics match with the operating environments to train their acoustic models. Gathering training data from loudspeakers playing recorded speech utterances are far more practical than from human speakers. This paper presents results from speech recognition experiments providing practical insights on effects caused by utterances re-recorded form loudspeakers. A clean-speech corpus of sixty human speakers was built using two different microphones and their playbacks were re-recorded. Results show that, with minimal lexical constraints, accuracies degraded for playback-trained system, even with no mismatches between training and test data. However, mismatches did not affect cases with tighter high-level constraints, such as number and limited-vocabulary word recognitions. A procedure to reduce mismatches caused by constructing corpus from playbacks was introduced. The procedure was shown to make the accuracy of a playback-trained system 48% closer to the one of the system trained with speech in matched environment.

This paper presents the simulation of a battery capacity for midsize plug-in hybrid electric vehicle (PHEV). The driving cycles are based on two drive schedules; the urban dynamometer driving schedule (UDDS) and Khon Kaen urban driving schedule (KKUDS) drive cycles. The model consists of mathematics equations for PHEV and it is simulated in MATLAB. As the results, battery capacity can be determined for the midsize car as desired.

A lot of Ultra Wideband (UWB) antenna designs, especially printed antenna, have been proposed so far. However, among those proposed designs, only single unit antenna analysis i.e. return loss and radiation pattern at particular frequencies are usually observed. This paper reports a deeper transmission analysis by considering UWB antenna as a system; so called system characterization. For a specific case, a pair of UWB printed monopole antenna with known single unit antenna performance was used for this study. Two-identical-antenna system was measured with Vector Network Analyzer (VNA), then its system transfer function, group delay, and waveform distortion are investigated. The results show that even the single unit antenna performance looks good enough but not so that well when the antenna is considered as a system. Nonlinear transfer function and group delay at some frequency ranges inflicts distortion in the waveform transmission which is crucial for UWB impulse radio scheme. Antenna performance evaluation in this study is provided in the term of its distortion by showing pattern of correlation between the transmitted and the received waveform.
