It is necessary to strengthen the construction of the "Three Systems" for promoting pollution reduction work entirely. Pollution reduction work is based on a set of scientific pollution reduction index system. In this paper, we used the Delphi Method to construct a pollution reduction index system, applied the Analytical Hierarchy Process to figure out each index weight in this system, and...
The friction welding supersonic C scanned pictures will introduce the noise in process of gatherring and conversion, and the disturbance of the noise to the image effects image's quality, which brought the enormous difficulties for image characteristic information extraction and analysis. Therefore, this article will propose a denoising analysis method, which obtains the scanned picture to the experiment...
This paper presents a model-based method for localization and measurement of various surface mounted devices. The proposed method uses all the image information and without feature extraction, it can be very accurate, efficient and robust. In our algorithm, the phase correlation is used for scale, rotation and translation estimation. In the part of scale and rotation estimation, we implement log-polar...
The ultrasonic testing signal of super alloy is always immingled with the scattering noise. According to the phenomena, this paper presents a kind of signal model of ultrasonic testing for super alloy and a wavelet transform de-noising algorithm based on modulus maximum. The characters of producing mode and wavelet transform of noise and signal are discussed. In the wavelet transformation mold maximum...
In this paper, a digital dc PD pulse detection system with bandwidth of 10 kHz - 40 MHz is introduced, which was developed using some artificial intelligence methodologies. Focus is made on digital detection, grouping and classification of random pulse signals generated by PD phenomena at dc voltage. Digital detection is developed only resorting to a band-pass filter, a high-speed digitizer (100 MS/s)...
