Abstract: Some features of impact destruction are shown on the example of a composite material with epoxy matrix and hybrid filler, magnetic particles of iron oxide of micron size and nanoparticles of iron oxide are used in the capacity of it. Dependence of the impact viscosity of the material on the temperature was discovered experimentally, which demonstrates the increase of this value at the decrease of the temperature.

Abstract: Architecture is the arena on which man's life unfolds, due to the constant changes taking place in life, deformability is demanded to increase the adaptability of modern Architecture. Thus, to achieve such deformability, research on the systematic hierarchy of architectures is carried out; indicating that the hierarchies are the intermediary of the inner transformation of the architecture and the formation process of architecture system is a process of gradual differentiation. With the development of the gradual differentiation process, the flexibility of architecture begins to fail while increasing its determinacy. The key point determining the adaptability of architectures lies in the inter-transformation between the various levels of sub-hierarchy systems. According to the complexity and hierarchy of the transformation, categorization and analysis with future study on the performance manifestation of architectural adaptability design are implemented.

Abstract: Through visit survey and field analysis, The hierarchy distribution of vegetation from the Dragon Bay to Guizhou Minzu University in Ten-li Strand artificial wetland park was studied. the main distribution and characteristics of vegetation, landscape distribution types of main vegetation and landscape design were analyzed. There were mainly 9 kinds of vegetation types, such as deciduous coniferous forest, evergreen coniferous forest, deciduous broad-leaf forest, evergreen broad-leaf shrub, bamboo forest, halophyte shrub, high grass, low grass and aquatic vegetation. By research on different hierarchy vegetation selection and different hierarchy vegetation landscape construction, it would provide forceful supports for city or town to take full advantage of the vegetation resources in artificial wetland parks and choose the reasonable configuration of landscape vegetation.

Abstract: As the urbanization of cities is rapidly developing in China, metropolitan regions establish the clustered power network planning scheme on the background of the clustered city planning of the adjacent areas. Base on the functional orientation and difference of clusters, as well as the theory of hierarchical clustered city planning, the article puts forward the power network planning thoughts and methods. As cluster becomes a planning unit, the load density method is applied in the differential load forecast and the location of substations as well as the path of transmission lines is selected with the thoughts of separation according to different layers and areas. And then, the results will be compared and verified with the planning scheme of the other clustered cities which have the similar function orientation and planning strategy. Finally, the planning methods will be standardized. The application in the power network of Cluster of Livable Education City in Zhengzhou has proved that the methods and steps of the power planning method proposed is able to meet the demand of the network development under the situation of the rapid growth of load.

Abstract: 3D animation technologies include FFD, Hierarchies and Kinematics (FK and IK), Dynamic animation, Keyframe, Time based animation, Non-linear animation, Path animation, Layered animation, and Motion capture animation etc. They are related with the efficiency of 3D animation. This thesis discusses these technologies separately and suggests methods to enhance the efficiency of 3D animation.

Abstract: This article defines a new self-resolving message protocol HML by departing self-describing area and data area. This protocol has limits of the layers of description area, so it could have good parse performance. The feature is proved to be true by compared with XML and ISO8583, and the protocol could be used in communication between layers in high concurrent process system.

Abstract: The reconfigurability of Manufacturing Execution System (MES) means that it can adapt to different manufacturing environment and application requirements rapidly and easily. A Reconfigurable MES Model (RMM) is discussed with a hierarchical architecture including Production Object Level, Business Activity Level, Business Function Level and Organization Level. The elements of each level are defined, and the implementation mechanisms of reconfigurations are analyzed in detail. Finally, an example is presented to prove the validation of RMM.

Abstract: The process time of aircraft assembly line is easily influenced by the efficiency of workers, the supply circumstance of components and the assembly quality. While the aircraft assembly line is hardly to reconfigure after it is in use, in order to optimize the assembly line before its application, a new object-oriented modeling method based on hierarchy and stochastic petri net has been put forward in this paper. The behavior and the structural characteristics of the model have been analyzed according to the solution of linear invariant. Finally, the model of aircraft wing assembly line has been established as an example, which proves the feasibility of the modeling method.

Abstract: In our real estate enterprises, the rapid growth and lopsided organization structure have become the obstacle for the development. This paper regards real estate enterprise as the research object. Based on the foundation of substantive investigation and expert consultation，considering the practical situation of real estate enterprise, following the basic principles of index system design of organization structure adaptability evaluation, this paper constructs an index system of organization structure adaptability of real estate enterprise evaluation. Combining AHP, Grey System Theory and concrete examples, this paper works out the evaluation grade of organization structure adaptability of real estate enterprise.

Abstract: Village as the basic prototype, most of the Chinese ancient towns have formed distinctive spatial structure in the joint action of multiple factors. Space of Chinese ancient town embodies hierarchy structure from large to small in the process of formation and development. The space system of geography, town, environment, architecture, livingmaterial produce hierarchy structure, the higher level including the lower level, the lower level reflecting the higher level, and forming system of compound spatial structure in Chinese ancient towns in the end.
