Authors: Wang Zhen Duo , Wang Jing , Wang Huan
Published: May 2014

Quantization methods are very significant mining task for presenting some operations, i.e., learning and classification in machine learning and data mining since many mining and learning methods in such fields require that the testing data set must include the partitioned features. In this paper, we propose a spheriform quantization method based on sub-region inherent dimension, which induces the quantified interval number and size in data-driven way. The method assumes that a quantified cluster of points can be contained in a lower intrinsicm-dimensional spheriform space of expected radius. These sample points in the spheriform can be obtained by adaptively selecting the neighborhood at initial observation based on sub-region inherent dimension. Experimental results and analysis on UCI real data sets demonstrate that our method significantly enhances the accuracy of classification than traditional quantization methods by implementing C4.5 decision tree.

Authors: Zhao Xiao Qing , Shang Peng
Published: May 2014

Tapered interference fits can avoid the influence of keyways on the parts strength and transfer large torques. In this paper, a model was developed to study the influence of the taper on the interference fit between a propeller hub and a shaft. Using the classic elastic plane stress theory, the exact solutions of the radial stresses, tangential stresses and radial displacements of the propeller hub and shaft are derived. Then the calculation method of the magnitude of the tapered interference fit was presented. Finally taking a screw propeller system as an example, the above solutions were calculated by using the numerical method. The results show that the taper plays a key role in the interference fit. Improving the stress distribution of the propeller hub is an effective approach to increase the connection strength. The present analytical solutions are expected to be useful in the structure design of tapered interference fits for propeller hubs and shafts.

Authors: Sun Qiu Dong , Zuo Jian Cun , Shao Yu Feng , Gui Lin
Published: May 2014

Although the general random scrambling based on pixel can achieve a good chaotic effect, but it can not change the histogram of a digital image. We introduce the random scrambling into the domain of discrete cosine transform (DCT) of image and scramble the coefficients of DCT to improve the performance of scrambling. Firstly, we did 2-D discrete cosine transform to the original image. Secondly, we scanned the coefficients matrix of DCT by Zig-Zag scanning to get a 1-D sequence, and then we scrambled this sequence by 1-D random scrambling algorithm. Thirdly, we did inverse Zig-Zag scanning to the scrambled sequence and reconstructed the scrambled image from the chaotic coefficients matrix by 2-D inverse discrete cosine transform. Finally, to further improve the scrambling degree of the reconstructed result, we scrambled it again in space domain to gain the encryption image. Experiments show that this algorithm is effective at visual evaluation and is more stable in scrambling degree than Arnold transformation.

Based on the investigation data of mercury (Hg) in waters in Jiaozhou bay during time peroids of 1979 to 1985 (absent of 1984), this paper tried to analysis the content, pollution level and theis temporal variations of Hg in Jiaozhou Bay, to reveal the changing trend of Hg, and to provide basis for pollution control of Hg in the bay. Results showed that, during 1979-1985, water in Jiaozhou Bay had been polluted by Hg in certain levels. For seasonal variation, there was a dicreasing trend form summer to winter in 1979, 1981 and 1985, and an increasing trend form summer to winter in 1980 and 1983. For annual variation, there was an obvious decreasing trend of Hg pollution from 1979-1982, while from 1982-1985 an increasing trend occurred. The temporal variation of Hg in Jiaozhou Bay reflects the conflict between economic growth and environmental protection. Having in mind that the environmental carrying capacity of Jiaozhou Bay is not unlimited, and the environmental disruption might finally cause economic loss and disasters to the human, we believe that the dischargd load of Hg should be limited in a suitable amount.

With the rapid development of Internet, it has been an important channel to access, publish and deliver information. Apparently, Internet has been a part of social life. However, our urban public transportation management systems still require to be improved. There are few methods available for people to search public transport routes. The most popular method is asking people or searching on a transportation map. An urban public transportation management system allows people to search public transport routes through Internet easily and conveniently. By collecting stop information on the routes, people can make a better travel plan before leaving home. The main module in the system is the transportation query module, the functionalities of which include route query, stop query, and station-to-station query, and station query; while the management module deals with operation processing on tables, such as insertion, modification and deletion, and responses to questions in guest books.
Analysis of Vertical Dynamic Response of Simply Supported Beam Traversed by Successive Moving Loads
Authors: Wang Xiao Ping , Li Ming Shui
Published: May 2014

In this paper, The vertical vibration’s analytical expression of Euler-Bernoulli beam traveled by moving loads is used to analyze the effect factors such as vehicle speed and damping ratio. The calculating program is made with MATLAB to analyze the dynamic response of a bridge as an illustrative example. A 32 meters simply supported beam traversed by moving loads of 8 ICE3 motor cars is analyzed. The calculation results show that the maximum displacement of the bridge appears at or near the mid-span and it has nothing to do with the position of the loads. The dynamic amplification coefficient of displacement at mid-span is not linearly increased with the vehicle speed improving. The damping ratio can decrease the dynamic response of the bridge dramatically, especially at the resonance speed.
