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.

Numerical control milling machine with a special transformation can be achieved the involute path processing functions. By using Fan method to process a way to synthesize involute track requirements and involute contour processing. This method is particularly suitable for gear modulus m ≥ 12 ∼ 40 of the big modulus gear machining, and omit the big modulus gear-specific complex tool manufacturing. Another advantage is that as the basic parameters of the coordinates programming trajectory calculation as a way to carry out involute trajectories run control, gears accuracy can be effective control and assurance. Furthermore, it can be revised and the edge of the involute tooth surface in the tangential connection.

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.

Standard programmable logic controller (PLC) based proportional-integral- derivative (PID) was originally employed as part of the food production line control strategy, but after observing the response of those process due to measured disturbances during normal operation, it was evident that PID control could not meet the desired cooking specifications. It was decided to pursue advanced process control strategies as a means to meet the food production specifications. The problem of this research study was to design and analyze the performance of a PLC-based model state feedback controller implementation for an industrial food production line, and to determine its viability in comparison to commercially available PC-based model predictive controller implementations applied to food production line. © (2012) Trans Tech Publications, Switzerland.

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.

At present, there are still many problems in the development of green logistics in China, which is attributed to the lack of theoretical research and the backward concepts of our government, enterprises, consumers and the public. This paper starts from the theory basis of green logistics, discusses the connotation of green logistics and its influence to sustainable development, gives particular analysis on the situation of green logistics in China from the government, enterprises and consumers' stand, and finally draws a conclusion that the development of green logistics needs government's leading, enterprises' participating, consumers' participation and intendance, and scholars' theoretical support, etc. © 2011 IEEE.

In order to increase the designing precision and study the main factors influencing the stability of metal elastic-jumping membrane, a set of experimental equipments have been designed to test the stability of metal elastic-jumping membrane. The laws of influencing the stability of elastic-jumping membrane were studies by changing the thickness, high, radius etc structure parameter. It shows that the increasing of high and thickness can enhance the distortion rigidity of metal elastic-jumping membrane, result in the increase of critical load at losing stability; the increasing of diameter can reduce the distortion rigidity of metal elastic-jumping membrane, result in the decrease of critical load at losing stability. At the same time, the correctness of finite element model was confirmed, and the basis was established for finite element method applying in optimizing design of metal elastic-jumping membrane. © (2011) Trans Tech Publications.
