RFID radio frequency identification is a non-contact automatic identification technology. As to the features that of current mobile phone RF system operating frequency range about 900-2400MHz UHF band, and the logic control core has a strong ability of controlling and data processing capability for consisting of dual kernel ARM9xx and DSP C55X. On this basis, by modifying the mobile phone operating system, set the mobilephone operating at max power 0.25w,realized a RFID reader to read the passive UHF tag supplied with the radaited enenrgy from mobilephone. The experimental results shows that the reading distance can be at least 5-2 cm, fully meet the individual to get products information easily, and it's valuable for the mobile phone users. This RFID devices can overcome the traditional RFID terminal's bulky inconvenient to carry and expand the mobile phone functions. © 2010 IEEE. Source

Nowadays, People's living standards and health consciousness are gradually improving, so that the people are having increasing demands for public sports venues and facilities. It's hard to meet the people's demands if the construction and operation of public sports venues rely on the government's investment only, while it would be a good channel to attract private capital to participate in the operation of our public sports venues. From various angles, this paper researches and analyzes the factors of private capital's participation in the operation of China's public sports venues. © 2011 Springer-Verlag Berlin Heidelberg.

One of the significant features of CNC technological superiority is in the practical applications, according to the necessary movement of processed parts required, we can use generating method to transform CNC machine tools and receive the desired results. This article discussed under the premise that lack of special equipment, transforming ordinary horizontal CNC milling to machine worm gear. The advantage of this numerical transformation approach is using the processing functions of thread and tapered thread instruction, skillfully translating into control of the CNC machining worm, expanding the CNC machining capabilities and the scope of practical application. Also apply the advantages of CNC technology, reduce or eliminate the accumulation of worm in the processing of pitch error which makes the worm processing precision and smoothness of worm drive better. This paper discussed the principles of numerical control transformation, transformation of milling machine structure and the conversion calculation of parameters in programming, analyzed the causes and processing effects of worm gear processing errors control and accuracy improving.

When faced with the large-scale data set, Kernel principal component analysis (KPCA) is infeasible because of the storage and computational problem. To overcome these disadvantages, an accelerated power method of computing kernel principal components is proposed. First, the accelerated Power iteration is introduced to compute the first eigenvalue and corresponding eigenvector. Then the deflation method is repeatedly applied to achieve other higher order eigenvectors. The space and time complexity of the proposed method is greatly reduced. Experimental results confirm the effectiveness of proposed method. © 2011 Springer-Verlag. Source
