Abstract: From the three aspects which conclude the strength and level, the function and the development condition of the competitive sports, it analyzed the competitive sports sustainable development system of host countries of the Olympic Games after the period of Olympic Games. From the three aspects which conclude the regulation thoughts, modulation methods and regulation ways, it constructed the competitive sports sustainable development’s system regulation of host countries of the Olympic Games after the period of Olympic Games. It introduced the intelligent control methods of the fuzzy control, the vague control, the set control, extension control, the rough control, fuzzy extension and consultation control and so on, as well as proposed the viewpoint that carried on the control by using the intelligent control body of the intelligent control integration, and established the intelligent control body model.

Abstract: Based on the analysis of concept and elements of mass customization which is mainly related to the area of production, the concept of mass customized logistics is proposed and analyzed. And then, the operational modes of mass customized logistics are illustrated at length. Finally, some strategies to achieve mass customized logistics are proposed and discussed.

Abstract: The paper discussed the relationships among specific human capital, information structure and innovation pattern. The organizational pattern of technological innovation is called innovation pattern in short, which includes two typical patterns: internal and external innovation from the perspective of transaction-cost theory. Information structure includes horizontal and vertical information structure, and the degree of human capital specificity is different in different enterprises. Based on a detailed analysis to the connotations of specific human capital, information structure and innovation pattern, the paper analyzed the relationships of them from theoretical perspective, and considers that enterprise’s horizontal information structure corresponds with special human capital and internal innovation pattern separately; while vertical information structure corresponds with versatile human capital and external innovation pattern separately.

Abstract: As the last working procedure in the paper production process, re-winder control technology is crucial to the quality of finished paper scroll. To obtain the paper scroll with inner tight and outer loose, the control of bottom rollers must satisfy the double closed-loop feedback control with torque difference. While the feedback control exists time-delay and may cause the slowness of system response. Here on the basis of re-winder production process and control requirements, a novel feed-forward control tactics is proposed to combine with feedback control. According to the compensation of feed-forward control, rapid system response is obtained and system performance is improved. And corresponding simulation shows the validity and feasibility of the feed-forward control tactics.

Abstract: A stable image mosaics algorithm based on PSO and SIFT is proposed in this paper. It adopts SIFT operator to extract corner point feature and finishes gray cross correlation matching, most false matches are eliminated by transcendental knowledge and constraint, then the transform matrix initial value between matches in two images is calculated, the optimal value of this matrix is acquired by PSO, finally, the image mosaics with no gap is accomplished. The experiment results prove the validity and practicability of the proposed method.

Abstract: In many of the application areas for reasoning about knowledge, it is important to reason about the possibility of certain events as well as the knowledge of agents. This paper introduces the concept of belief degree of an agent with respect to a fact at a given point. Moreover, based on the belief degree of agent i , a pseudo metric on the set of agent i’s graded knowledge are established. Lastly, two kinds of models for approximate reasoning are proposed, which provides a possible framework for an agent to develop approximate reasoning at a given point by using its graded knowledge.

Abstract: This paper discussed the mechanism of adsorption of the petroleum sulfonate and heavy alkylbenzene sulfonate on reservoir sand mixed with clay of Daqing oil field. The results showed that: the adsorption of surfactant increased with the increasing of the surfactant equilibrium concentration and clay content in the ASP floods systems; interfacial tension decreased with the increasing of surfactant content; the interfacial tension become higher after adsorption on the reservoir sand. Application result of weak base system is better than strong base, because of the lower adsorption and interfacial tension is provided.

Abstract: A new method based on the integration of principal component analysis (PCA) and radial basic function (RBF) neural network is put forward for selecting the real estate project. Firstly, principal component analysis (PCA) is used to reduce the evaluation index dimensions. And then, radial basic function (RBF) neural network is used to evaluate the real estate projects. In order to grasp this method better, finally, the paper provides a case to demonstrate the application of this method in selecting the real estate project. The case has shown that the method applied to select the real estate project is feasible and reliable.

Abstract: This paper deals with the approximation properties of a rational cubic spline with quadratic denominator. The rational cubic spline has two families of parameters and based on function values only. From the point of view of the magnitude of the optimal error constant, it found that this kind of spline give good approximation to the function being interpolated.

Abstract: In this paper, a rational cubic spline interpolation has been constructed using the rational cubic spline with quadratic denominator and the rational cubic spline based on function values. The spline can preserve monotonicity of the data set. The spline not only belongs to in the interpolating interval, but could also be used to constrain the shape of the interpolant curve such as to force it to be the given region. The explicit representation is easily constructed, and numerical experiments indicate that the method produces visually pleasing curves.
