Abstract: Fractals in building network models are objects which appear similar (at least in some statistical sense) at every lengthscale. We focus on produce the rectangular growing network models by constructive operations based on fractals, and show the scale-free behaviors of our models. We, also, try to find those nodes like “hubs” in the models by spanning trees having maximal leaves.

Abstract: At present the majority of association rule mining algorithm only uses support and confidence to evaluate association rules, association rules which may contain a large number of redundant, meaningless, Introducing the concepts of hyper-graph and system and exploring to construct the hyper-graph on the model of three-dimensional matrix. According to the characteristics of Big Data, the new hyper-edge definition method is adopted combining the concept of system, thus improving the processing capacity.

Abstract: The centralized model of B / S structure is adopted in the current distance education learning classroom, there are some drawbacks of this model, like the resource duplication, crowded user access, poor system scalability and so on. Adoption of cloud computing technology can collect all the distance learning classroom resources to build a "cloud" platform, students can easily access the resources they need by using different terminal devices locally. By analyzing the meaning of cloud computing, application mode and characteristics of cloud computing, the building contents and methods of distance classroom "cloud" is proposed.

Abstract: The Android operating system is the most popular handheld devices operating system, the cloud computing is taken for processing large scale data efficiently, the commonly used scheduling technology of cloud computing needs to assign the user jobs to the reasonable resources for execution, the scheduling performance is not good. The mass data scheduling model is proposed based on application service quality limitation, and the cloud computing data scheduling principle is analyzed on the Android platform, the Android platform user requirements and the resources of node vectors are described, independent computing ability of users are ensured. On the basis of service quality parameters computing, cloud mass data scheduling tasks are matched to the tasks on the Android platform, the different service quality requirements of user can be accurately judged, the resources is provided to the user according to the requirement, the scheduling overhead is reduced after the service quality matching, the efficient scheduling of mass data is obtained. Simulation results show that the proposed scheduling model has better performance in time consumption and user satisfaction degree, the new model has lower CPU load ratio on the Android platform, it is a high efficient mass data scheduling model of cloud computing on the Android platform.

In the face of cloud computing environments with massive data center, an efficient scheduling model need to be established. In order to solve massive data processing inefficiencies, redundant business systems and data silos and other issues, this paper proposes a scheduling model of migrating technology based on efficiency optimization virtual machine to meet the massive data efficiently scheduling requirements. Experimental results show that the improved algorithm can effectively advance the efficiency of cloud computing massive data scheduling, with high feasibility and applicability.

Abstract: A dynamical system modeling method based on cell mapping is proposed in order to describe the system statistic property, and then a discrete optimal control table is constructed through each state cell excited by all input level recording the optimal cost value at the same time. Finally, a demonstration of the method is shown for the time optimal blast temperature set point control of a sintering machine.

In this paper, through the rich practical experience in the field of English teaching, on the basic of prototype category theory to study of English grammar teaching methods, the author attempts to explore the scientific and rational English grammar teaching concept and strategy.

Abstract: Based on the threats of cloud computing security, combined with the principle of private cloud computing, this paper introduces the variable dimension fractal theory into the cloud computing and security policy model, and puts forwards multidimensional data model C2MDSM of the cloud computation. The model can protect 2D and 3D protection of user information in a private cloud space. Through the 3D fractal it greatly improves the user use of cloud resources, and improves the security of information, which realizes the true sense of the reasonable distribution for cloud resources. In order to verify the validity of the mathematical model and the algorithm designed in this paper, we use the MATLAB software to draw 2D and 3D fractal, and obtain the number of cloud users, security level and calculation residual results. It provides the technical reference for the research on cloud computing.

In order to achieve optimal scheduling of vehicles, saving transportation costs, and taking into account the defect of high computational complexity exists in traditional vehicle scheduling algorithm, which is not practical for application, this paper proposes an improved vehicle scheduling optimization model. Experimental results show that the new algorithm is applied to large-scale logistics management optimization model, which can improve its practicality and effectiveness.

Abstract: Mobile computing environment is relatively complex environment. This paper uses the optimization mathematical model step by step to improve the mobile computing algorithm, and improves the interoperability of mobile computing. And we introduce this model into the starting transient dynamics analysis for athletes, and establish the analysis system of starting transient force and speed. In order to verify the validity and reliability of the system, we use Web development platform to test the system, and use the VC software to calculate the maximum speed of athletes in different pedal angles. Through calculation we find, the instantaneous speed of athletes is different with different pedal angel. When the pedal angle is 45 degrees, the speed of athlete is faster than that in 30 degree and 60 degree. It provides the technical reference for the research on athletes starting running optimization scheme.
