Abstract: The cooperation of urban traffic control system and urban traffic flow guidance system may perform an important role in alleviating traffic congestion. To achieve this objective, a dynamic traffic coordination control model of traffic congestion based on synergetics is proposed in this paper. After that approach, a simulation scheme based on VISSIM 4.2 is carried to evaluate the reliability of the model. The results proved that the whole system could benefit a lot.

Abstract: The dislocation self-organization processes in near-surface silicon layers of Si-SiO2 during high temperature oxidization have been investigated. It was observed the complex destruction of these layers caused by relaxation of mechanical stresses. We have proposed the defect formation mechanism of near-surface layers in Si-SiO2 structure. For self-organization processes to be explained, the synergetic method was applied. It was shown that the formation of periodical dislocation structures at the interface is a consequence of the spatial instability of the dislocation distribution in the crystal, their self-organization due to correlation effects between the oxygen diffusing along structural defects and an ensemble of dislocations.

Abstract: Senior title intellectuals not only shoulder the important task to train high-level persons, but also are the disseminator of modern knowledge and the main force of scientific work.. Their health status related to China’s scientific and technological progress and social development. There are many factors. The research perspective is oriented to the condition of the Universities of Hei Longjiang Province senior teachers. In the process of development of city environment system, if people want various elements that constitute the city environment to interact, digest or absorb the city rubbish and waste which is used to develop production, the symmetry must be broken, making the city environment and the teachers’ health in order.

Abstract: Catastrophic failure of rock mass is a kind of serious geological hazard which usually happens during deep mining excavation and underground engineering construction. Though many investigations have confirmed that it was strongly relate to dynamic disturbances, the disturbing mechanism is still not well-known. The purpose of this paper is to offer a theoretical method to analyze dynamic disturbances induced catastrophic failure. On the basis of synergetic analysis, we established a generalized Langevin equation to describe the nonlinear evolution process of rock mass by considering stochastic dynamic disturbances. Then we further derived a stochastic potential function to research the inductive effect of dynamic disturbances and critical property of catastrophic failure. Results indicate that the influence of dynamic disturbances on the stability of rock mass depends on both the static state of rock mass and the external disturbance intensity. The catastrophic failure threshold is the function of disturbance intensity and control parameters of rock mass.

Abstract: With the guidance of sustainable development strategy, countries around the world poured to carry out the conception of circular economy into the strategy of protecting ecological environment. As an important mode of circular economy, Renewable Resource Industry increasingly draw every parts of worlds attention. However, the Renewable Resource Industry is a typical Institutional Economy, which needs the role of government as well as the market mechanism. However, Renewable Resources Industry is in the primary stage of development, whose policy system is not thorough and guiding concept is not clear. In this background, guided by the full life cycle theory and collaborative theory, starting from the features and realistic demand of Renewable Resources Industry, the authors structure an industrial synergy policy framework for Renewable Resources Industry, which including design policy, manufacturing policy, consumption policy, recycle policy, demands policy and government policy. The research findings provide us with systematic ideas and methods to make the Renewable Resources Industry policy.

Abstract: In order to evaluate the level of roads safety, this paper proposes a model of traffic accidents which is derived from theories of synergetics. In this study, a great deal of field survey date is obtained via a set of physiological and psychological detection devices. By analyzing data combined with driving comfort threshold, a model of traffic accidents is founded according to different effects, caused by traffic factors.

Abstract: This research concerns the metals behavior as varying, with increasing cyclic stress level, in the transition range between the ultrahigh cycle (UHCF) and high cycle (HCF) fatigue regimes. Having analyzed the synergetics of surface crack initiation, the authors propose to identify the UHCF-to-HCF transition with a certain stress level corrected, with the respective dimensionless functions, for the effect of the environmental attacks, temperature, surface roughness of the test piece, etc. on the crack initiation behavior. Subsurface initiation of a fatigue crack occurs in the test-material susceptible of a deformation-induced transition to superplasticity state, which favors formation of the nanocrystalline zone bordered by a fine-granular area Another case of subsurface cracking is in that a local even area forms owing to the vortex-like deformation combined with the diffusion of the retained gases toward and into the discontinuity. A proposed equation is plainly descriptive of the subsurface growth of fatigue-cracks and allowing to acquire the crack growth duration from the fractography data.Nomenclature
