Inclusions in steel materials are generally composed of oxide, silicate from silica, sulfide, and other chemical compounds. These inclusions in steel cause stress concentration on the contact surface between inclusions and steel base, which result in a quenching crack and a decrease of fatigue strength. The inspection of inclusions in steel is high in demand, and is typically carried out manually. This study used a rule-based methodology to develop a division-making architecture for a digital evaluation system. The results from comparison experiments showed that the difference of evaluation grade between digital and manual evaluations was 0.5. Moreover, the time spent on digital evaluation was 30-50 times faster than manual evaluation. In summary, the digital evaluation developed by this study for inclusions is suitable for metallographic inspection.

This research in multiple quality objectives of the turning and milling multitasking machining is based on the Taguchi process and the fuzzy theory. These two methods can quickly find the best processing parameters to obtain the best surface roughness and dimensional accuracy and reduce the research cost and save research time. In this research, the Taguchi robust process $L9 (3^{4})$ orthogonal table was used to find the individual optimized process parameters. The control factors used were spindle speed (RPM), feed (mm/min), and C-axis brake pressure (kg/$cm^{2})$.), the axial cutting depth, and then taking the surface roughness and dimensional accuracy as the characteristic indicators, and then the respective signal-to-noise ratio (S/N) is grayed out according to the experimental sequence to generate normalization, and the gray correlation coefficient is obtained. Further, a Multiple Performance Characteristic Index (MPCI) is obtained. The research results clearly demonstrated that the overall results of the process optimum parameters obtained by using the measurement indicators of multiple quality characteristics prevail the results of the individual optimized process parameters.

The objective of this study was to explore the feasibility for rapid diagnosis of heavy metal Pb and Cd cross contamination in agricultural soil with hyperspectral image of rice plants. Several data pretreatment methods were applied to improve the diagnosis accuracy. The best diagnosis accuracy of SVM model were all above 75% for any none, low, medium and high concentration stress based on the spectral band of second derivative. To the best of our knowledge, this is the first study identifying Pb and Cd cross contamination by using hyperspectral images. The results indicates that it is feasible to diagnose the Pb and Cd cross contamination in agricultural soils from observation of rice plants using hyperspectral image.

Taiwan has suffered from debris flow disaster in the past decade. Potential debris flow has increased from 485 streams in 1991, to as high as 1719 streams now. These natural disasters affected villages and the safety of Taiwanese residents. As a result, it is necessary to look into more debris flow relevant researches and analytical work.This paper is investigating debris flow streams and analyzing the characteristic of particle river bed. Through the use of fractal theory, we are able to figure out debris flow stream's fractal quantized value.

This study conducted simulation analysis and experiments on novel piezoelectric acoustic wave components, using finite element analysis software to explore the dispersion relation of piezoelectric components with various periodic structures, shapes, and thicknesses. A microelectromechanical system was employed to etch micropatterns onto films. This study developed four different piezoelectric structures, namely flat, periodic, and single-and dual-defect structures, and measured the frequency response variations in radio frequency and phase signals. The acoustic wave responses of a graphene-like structure with defect distribution were analyzed to develop, design, and fabricate a novel oscillator component. In addition to exploring the bandgap effect in the graphene-like structure model, this study also developed a frequency sweep model for the design of novel oscillating components.

An optical add/drop multiplexer, based on asymmetric Bragg couplers with liquid crystal filled in a core of the waveguides, is fabricated. The asymmetric Bragg couplers (ABCs) are fabricated by employing micro-electro-mechanical systems (MEMSs) technologies and holographic interference lithography. In one of the core trench, the liquid crystal is dripped to increase the average effective refractive index of the waveguide. The experimental results show the device is feasible in dense wavelength division multiplexing (DWDM) systems.

Postprocessor converting the tool path into numerical control (NC) program is the key technology of NC programming and also an important medium between CAD/CAM system and machine tool. The purpose of this study is to analyze the tool path file NC Intermediate (NCI) produced by the commercial software Mastercam, including the data of the tip point, contact point, contact point vector and other related information. A window-based conversion interface written by Visual C # was developed to transform the NCI file to the required multi-axis NC program and a process operation sheet for the table/spindle-tilting type of five-axis machine tool configuration. It confirms the feasibility of the proposed scheme through verification using the solid cutting simulation software VERICUT® and trial-cut experiment.

Based on MVS/SfM of the image processing technology, UAS photogrammetry is able to produce high precision orthophoto. The inner precision data of orthophoto can be provided after aligning photo in precision report, including ground resolution of the total image, the RMSE of control point and checkpoint by image processing software. However, while measuring the coordinates of image point from orthophoto in surveying project, we cannot realize the real amount of error from report. For obtaining the real amount of error when measures image coordinates from the orthophoto, this study conducted e-GNSS measurements on the control points, check points and feature points selected from the image. And compare the coordinates of the image measurement with the measured coordinates. The result finds out that the average deviation of control points is about 2.9 cm, the average deviation of check points is about 4.0 cm, the average deviation of feature point is about 6.1 cm. The data of feature point shall be taken as reference in project, for decreasing deviation, shall decrease image deviation in prior concern.
