Authors: Lv Tai , He Pei Ye
Published: October 2014

For a reduction ofthe volume and cost of equipment, some thermal power plants have no gas heater in their desulfurization systems. Because of desulfurized gas with high humidity, residual dust, and limestone slurry, induced draft fan (IDF) is often subject to vibration caused by dust accumulation while operating, resulting in occasional shut-down for dust cleaning. To solve this problem, fine sand was added to jet nozzle in the circumstance of severe dust accumulation, to enhance cleaning effect in this study. The Fluent software was used to simulate the static pressure distribution on non-working surfaces of the IDF blades with different sand flows. Results showed that the addition of fine sand could enhance the static pressure on non-working surfaces. The optimum ratio of nozzle flow to sand flow was concluded. This was of great significance for IDF on low load to prevent dust accumulation vibration and to keep safe and stable operation.

Then an analysis of the hydrodynamics and the long term mass transport behaviors under backwater effect in the Taohuaxi River and Longxi River was presented. The results show that mainstream backwater effect plays a significant role in tributary during low-water period. And distinct circulation was shown in tributary estuary. However, in high-water period, estuarine circulation area in Longxi River decreased and disappeared, while the one in Taohuaxi River is still evident. Different input action from mainstreams to tributaries has been discovered.

Published: October 2014

Industrial water demand forecasting is needed for the effective planning and management of water supply systems. The paper first made impacting factor analysis of industrial water demand. Data analysis showed that there was a converse “U” type relationship between industrial water demand and industrial value added. There was a negative correlation relationship between industrial water demand and the recycling rate of it. With multiple regression method, industrial water demand forecasting model was established. In the supposed scenarios, we applied the model to predict Chinese industrial water demand in 2014 and 2015.The results were 141.04 billion m3 in 2014 and 137.79billion m3 in 2015.

An Edge Detection Algorithm for Image Corrupted by Impulse Noise
Authors: Shen De Hai , E Xu , Zhang Long Chang
Published: October 2014

In order to improve the edge detection efficiency, and decrease the impulse noise impact on the edge detection, a new edge detection algorithm for impulse noise image is proposed. The algorithm combined the median filter idea, and used cross convolution template to calculate image gradients of horizontal and vertical direction. First, detected the point that will attend gradient calculation by threshold, for the noise point, its value will be replaced by median of those points associated with it in detection window. For non-noise point, we directly calculate gradient it initial pixel values. Experiments show that, the new algorithm has strong suppressing noise ability for images corrupted by impulse noise, the extracted image edge is also fine, the outline is clear, the algorithm is better than the traditional Sobel algorithm and the wavelet transform algorithm in noise suppression performance and the detection efficiency, it has strong practicability.
Detection of Unattended and Removed Objects in Public Areas
Authors: Huang Xiao , Zhao Yong , Cheng Zhong Xin , Yuan Yu Le , Liang Xiao Hui
Published: October 2014

This paper presents a novel approach to detect unattended and removed objects from a single fixed camera video for surveillance applications. In this paper two backgrounds rather than any tracking information are employed to detect static foregrounds. Each of the backgrounds is modeled by three Gaussian mixtures. We make a subtraction between two foregrounds extracted by the background subtraction method to initially determine the static regions. Then the region-level density analysis and texture information are combined to remove false static foreground regions caused by illumination changes and objects that are in the static-moving transitions. Finally, classification of the unattended and removed is determined by a method that compares color histograms of the static foreground zone and its extended areas in current frame. Experimental results show that our method can work well in simple scenario as well as complex environments with an unsmooth background.

This paper presents a novel image acquisition technology for colorless raised characters. First, a grating image modulated with the height information of raised character is captured through a vision system; then, the Fourier transform method is used to get the phase of the grating image; finally, a rational design phase unwrapping method is designed to reconstruct the grayscale image of raised characters. Experiments show that the proposed method can get the well-separated images of raised characters.
Fuzzy Set Based Clustering Algorithm of Web Text
Authors: Wan Hong Xin , Peng Yun
Published: October 2014

Web text exists non-certain and non-structure contents ,and it is difficult to cluster the text by normal classification methods. We propose a web text clustering algorithm based on fuzzy set to increase the computing accuracy with the web text. After abstracting the key words of the text, we can look it as attributes and design the fuzzy algorithm to decide the membership of the words. The algorithm can improve the algorithm complexity of time and space, increase the robustness comparing to the normal algorithm. To test the accuracy and efficiency of the algorithm, we take the comparative experiment between pattern clustering and our algorithm. The experiment shows that our method has a better result.
Effect of Uniaxial Stress on Magnetic Permeability and Magnetic Loss of Low-Carbon Steel in Weak Alternating Magnetic Field
Authors: Li Xiao Yang , Han Zan Dong
Published: October 2014

The inverse magnetostrictive effect provides a chance to detect the stress by measuring some magnetic parameters. So it is important to learn the effect of stress on some magnetic parameters. A measuring system to measure magnetic permeability and magnetic loss and a device to load uniaxial tension and pressure stress were developed. The result shows that magnetic permeability and magnetic loss increase with uniaxial tension stress increase and decreases with uniaxial pressure stress increase. It is also concluded that the relative change of magnetic permeability and magnetic loss decrease with increase of the included angle between the directions of the stress and magnetic field. These results suggest that magnetic permeability and magnetic loss can be further used to evaluate the stress in low-carbon steel.

High precision calibration of Micro inertial measurement unit (MIMU) for large installation misalignment can improve the instrument and the practical use of the system precision. It can use high precision turntable to get the coarse value of installation misalignment angle as the optimization initial value, and take the standard deviation of turntable angular rate and the acceleration of gravity as the optimum index to find MIMU misalignment parameters using artificial fish swarm algorithm. Simulation and analysis are carried out based on the position and rate experiment. In addition, static navigation test is taken by using self-developed MEMS heading and attitude measurement system. Both the simulation and experimental results show that this method can improve the calibration accuracy of MIMU effectively with reduced of heading and attitude error.
