With the development of logistics, the firms on the logistics chain, especially the Chinese small and medium enterprises, find it very difficult to get the financial support from the bank, the launch of the logistics finance paves the road for the integration of the logistics firms and finance sectors to a certain extent, and is popular at home and abroad nowadays. Based on the previous study and...
Multimedia IT with forms like computerized adaptive test, human-computer interaction in oral test, computer scoring system, network scoring and data analysis used in higher vocational English tests has not only improved the efficiency, accuracy, objectivity and impartiality, but promoted the renewal and development of the idea and orientation, scope and testing design. Teachers are expected to learn...
In order to solve operation speed slowly for traditional kalman filter technique and the effectiveness is not ideal in processing the nonstationary signals, the traditional kalman filter is improved and applied into the actual measurement nonstationary vibration signals. Firstly, the traditional kalman filter technique is analyzed and the shortcoming using in gearbox fault diagnose is discovered,...
This paper reviews the literature on consumer-perceived risk under E-commerce context over the past 15 years. It begins by describing new risk of new shopping mode—E-commerce, and the specific definition of consumer perceived risk. Then, it summarizes the risk-reduction strategies in the new mode of shopping, and the main application of E-commerce perceived risk. In the end of the paper, the reviewer...
This paper puts the method of Jacobi elliptic function expansion into practice to solve such equations with self-consistent source in Physics, and takes a specific KdV equation with self-consistent source as an example. By means of Mathematical software, it concludes the dual-cycle exact solutions of Jacobi elliptic function, while the mold m limit to 1, these solutions will degenerate into the corresponding...
Some characteristic features of wastewater treatment processes were discussed, and according to its characters of time-varying, nonlinearity, complexity and uncertainty, it was presented that intelligent control was an effective method that could be used to achieve the automatic control of wastewater treatment system. The present developing situation of artificial neural networks in wastewater treatment...
