Abstract: In this contribution is presented application of evolution diagrams at the assembly process of at the intelligent manufacturing and assembly cell. At this assembly cell was designed new assembly configuration for next research to our department and institute. Intelligent manufacturing and assembly cell is situated at the Institute of Production Systems and Applied Mechanics. The complex design of assembly sequences at the intelligent manufacturing and assembly cell is realized on the basis of evolution diagrams and outgoing from knowledge about intelligent manufacturing and assembly systems. For intelligence increase of assembly process was this cell completed by additional sensors. This assembly process is possible to name intelligent assembly process.

Abstract: The article using Brusselator model analyses the evolution mechanism of industrial clusters. The study found, the formation of industrial clusters is an inner reinforcing cycle accumulation process, the competing interaction is an important condition for the evolution of industrial clusters, and cluster innovation driving the system to the state development more orderly, form the new dissipative structure, promote the evolution of industrial cluster.

Abstract: The dissertation targets on the evolvement of the Olympic architectures together with the analysis of some concrete historical cases. The dissertation has been divided into two halves, which are logically related. The first half is organized as follows: first, the historically evolvement of the Olympic Games over the past 100 years was illustrated via 4 important phases. Then it concluded the characteristics on the space layout of the Olympic architectures. Finally the technical and economical influences on the Olympic architectures were analyzed in detail. Within the second half, for each of the four characteristic stages, detailed elaborations were launched to cover the unique characteristics of the Olympic architectures in each stage chronologically.

Abstract: In this paper, basing on the prisoner’s dilemma model proposed by M.A.Nowak, we present a model to research the action of temptation to defect in prison’s dilemma model. Firstly, we determine whether a player changes its strategy depends on a Fermi equation which is related to the payoffs of the player and its neighbors. If the player changes its strategy next time step, it will select the strategy adopted by the one who gets the highest payoff among its neighbors as its own strategy. Form the results we find that when four neighbors are considered, the density of cooperators will present a downtrend. Well, when eight neighbors are considered, the density of cooperators will decline at the beginning and increase suddenly afterwards. When twelve neighbors are considered, if the density of cooperators is reduced to zero, cooperation will appear again. Thus, the increase of temptation to defect may promote cooperation.

Abstract: Urban rail transit network is a special complex kind of network, The lines and nodes' layout determine the entire network's features. This paper analyzes the topologic properties, degree distribution, average path length and robustness of Beijing subway network by matlab and it also analyzes the evolution of Beijing subway network, which can be worked for the future development of urban subway network planning and construction.

Abstract: This paper puts forward the method of obtaining new types of RV transmission. Research shows that the topological graph can effectively express the topology unit and topological structure of RV transmission; the process that through topology degradation and evolutionary method to Obtain the RV transmission of topology map and through the topology inversion to get the new organization is practical and feasible. The topological evolution methods have tie bar evolution, tree, increasing gear tooth ring and mixing superimposed evolution. The RV transmission topology inversion is implemented by the way of gear ring, Gear meshing, the gear, the shaft, tie rod and the frame. Method was developed to get the evolutions of a variety of RV transmission, and the evolution of a graph of the inverse mapping was enumerated. The topology graph theory methods used in the RV transmission for the structure of RV transmission innovation provides an important theoretical method.

Abstract: The leaning and evolutionary (L&E) algorithm of Agent for task oriented is deeply researched in this paper. Based on the relationship between tasks and the executive Agent, the importance of the research has been elaborated. Moreover, the algorithm is improved by considering the effect of environment and network structure. Reinforcement leaning and complex network have been introduced into the nonlinear genetic algorithm. Finally, some simulations of equipment acquisition tasks are made to test the validity and capability of the algorithm.

Abstract: As one of the most ancient buildings provinces on the ground, Shanxi ancient villages are determined by specific natural conditions, economic conditions ,customs, and social life style, and formed by historical development, creation, accumulation in the process of long-term , which lead to obvious regional characteristics. On behalf of ancient village reserved completely, Guoyu ancient Village has high research value. Through from two aspects of village evolution process, planning elements ,the paper researches planning form of Guoyu village.

Abstract: Since the discovery of Archaeopteryx, various theories have been suggested to explain the evolutionary link between reptilian dinosaurs and avian species and therefore the evolution of flight. Often these theories focus on the potential use for early wings, which are not yet developed enough for flight. Understanding the purpose of these ‘proto-wings’ is considered key to revealing the driving force behind avian evolution. A computerised, musculoskeletal model of a proto-wing was developed and used to analyse a simplified motion that is theoretically typical of proto-wings. Through biomechanical analysis we can infer if this could be feasibly made, what forces are significant in making such a motion and how kinematically and kinetically sound the simulation is. As such, the proto-wing model is a significant analytical tool for understanding pre-flight kinematics.

Abstract: The landscape spaces of Qijiang ancient town take on special combined characteristics of contrary space sequence. The space configurations are unique and diversiform, particular about the whole harmony between inner and outer environments, human and space. The space-time configurations reflect ordered, blending and continuous in inner and outer landscape spaces. The contrary space configurations experienced more than 2000-year historic evolutions. The landscape spaces have extended continuously and reasonably complying with the combined characteristics of contrary space sequences. But in the late of last century, a lot of the landscape spaces were destroyed. Analysis on the contrary space configurations and evolutions will help us to look for the relationships and rules of the original spaces, and supply references to recovering multidimensional and sustainable ancient environments spaces.
