In order to improve the security in the process of audio files in Internet communication, first Construct a generating chaotic sequence of six dimensional cellular neural network model, according to the principle of RSA asymmetric encryption algorithm, proposes a location of any number as a transmission key(Coordinate key) in the chaotic sequence and using the public key and RSA encryption algorithm for it. Then the number corresponding to this key position, as the starting point of Chebyev chaotic mapping, and to generate encryption sequence. Finally encrypt the original audio and send to receiver with the transport key. In order to verify the practicability of the algorithm, we made a simulation experiment, the complexity of the test the transmission key and comparison of the original audio and the encryption audio waveform figure, and proves the feasibility of this kind of encryption algorithm through the correlation analysis, spectrum analysis and sensitivity analysis. There is the broad prospect and the important application of chaotic and RSA encryption technology.

Power curve provided by wind generator manufacturer, which characterizes the steady-state operation condition of wind generating set, has deviation when it is used to analyze the real operating condition of wind generation set. This paper conducts the calibration of power curve of wind-driven generator and builds the forecasting model of wind power based on least squares support vector machine (LS-SVM). Simulation results have verified the efficacy of the proposed prediction model.

This study is focused on the analysis on soft power of Daqing Oil Corporations based on statistics from Chinese Oil Corporations, with consideration of theories of domestic and foreign soft power study. We analyzed degree of soft power from the six aspects including corporation culture, management level, social responsibility, innovation, corporation imaging establishment and resource. Further, the questionnaires to employees from Daqing Oil Enterprise were analyzed combined with analytic hierarchy process and fuzzy mathematical theory, by means of weight determination and evaluation procedures. Application of ANP evaluation is applied to analyze and determine the weight of soft power of Daqing oil companies. The method of selection and expert advice preliminary indicators, application Likert Scale for five indicators screening questionnaire was constructed including the six-level indicators. Our study indicated that Daqing Oil companies is vigorously practicing corporate social responsibility, as well as focusing on strengthening the integration of resources, and full force shaping the corporate image. Finally, Path to enhance the soft power of Daqing Petroleum is proposed.

Strategic management is a systematic project for multinational as well as Chinese corporations. Abilities to adapt to dynamic environment from exterior and interior are essential for strategic management in the sense of distinctive competence. Here we first analyzed the current status of Chinese corporations in culturing and maintenance of distinctive competence after applying strategic management. The countermeasures Chinese corporations have applied to catch up with their multinational rivals during the past twenty years of reform were further dissected. Then, taking the case of Chinese Baosteel Corporation and Japanese Mitsui Corporation, we have reported research on the background of these two leading companies in steel industry, reported comparison of their distinctive competence focusing on strategic management and discussed pitfalls of Chinese state owned corporations in the process of reform and internationalization. Finally, we have proposed three key measures that Chinese corporations should adopt for establishing and maintenance of distinctive competence in order to achieve a sustainable development.

In China, with the continuous blooming of economic growth, it is pivotal to construct a market economic system of high degree of integrity and credibility, which is essentially the demand to the fulfillment and converting of governmental function by further development of economic. However, in reality the lack of credibility in market has become the bottle-neck restriction to the healthy growth of Chinese market economy. The administration for industry and commerce is one of the key components of national macro-administration to market economy. Excellent models have been offered from experiences of how construction of national credit system promoted rapid economic growth in the developed countries. These precious and abundant experiences provided references for Chinese market economy, which is developing from a relatively poor credibility basis during converting and reformation. We analyzed sakes endogenously impacting proper functions of administration for industry and commerce, and hampering the process of socialism marketing system of sincerity, integrity and credibility. In addition, taking references of western public administration theories, we propose resolutions on valid positioning of the administrative departments, the governmental coordination of multiple sides, the strengthening of social credibility and the adaptation to demands of social development in assort with the healthy growth of market economy. This study is significant on illustration of the fulfillment of functions of administration for business and commerce authorities at various levels for the benign development of Chinese market economy
