Because of the problem of CSEM about the air wave in the shallow water, the research of time-frequnecy analysis technique is used to suppress the air wave in this paper. The basic idea is: because of the CSEM signals speed are different in the air and submarine, so the time which received by the receiving points are also different through these two kinds of ways. Using the time-frequency analysis technique and theoretical calculation, we can determine which part of the signal is spread over the ocean, so as to suppress the air wave effectively. This paper lists several methods of time-frequency analysis, such as Short-time Fourier transform, W-V distribution, Wavelet transform, Hilbert Huang transform.

The algorithm has a quantum-behaved particle swarm global search capability. And In order to accelerate the convergence speed, the k-means algorithm is used to optimize every particle .Through the adjustment of the value of the fitness function, our algorithm can search for the optimal clustering number of clusters, so the number of clusters and centers are not subject to subjective factors. Extensive experiments verified the effectiveness of the algorithm.

Published: September 2013

In recent years, not only the academics pays close attention to the creative industries, but also enterprises and the government keep a watchful eye on it. Cooperation and competition behaviors of enterprises will decide their competitiveness directly, thereby affecting the competitiveness and future direction of our creative industries. In this paper, based on cooperation and competition behavior in creative industrial clusters, we establish symmetric game model between two core enterprises and asymmetric game model between the core enterprise and the adjacent down-stream one by using evolutionary game theory, then analyze its dynamic evolutionary procedure. The result show that the systems evolutionary direction is closely related to players payoff, and influenced by cooperation profit, initial cost of the cooperation, capacity for independent innovation, cooperation successful rate and systems initial status. At last, some suggestions are offered for our government which can provide a theoretical basis for integrating creative industrial clusters.
Strategy Study on China E-Business Service in Big Data Era
Authors: Xu Wen Jin
Published: September 2013

The era of big data means that the data grows in explosive way,but this massive growth of the data does not mean lots of information. In this article, we show that such big data cannot be used in the same way as before; otherwise from the point of view of energy consumption, the computer system cannot afford it. At the same time, the information collected at this stage is also unable to meet the impact of the arrival of such a big data. The big data is taken from the application. To complete specific, we should often choose the rational mode of information processing or the algorithm. In business computing, offline computing and real time computing are the two ways to process big data.
