Abstract: At present, China strongly advocated the development of recycle economy, while most studies are starting from the promotion of economic development and reduction of environmental pollution rather than from the promotion of employment. This paper summarizes some experiences of promoting employment by developing recycle economy in China and abroad, and proposes some advices to solve problems that emerge in the process of developing recycle economy. It puts forward a new view that the recycle economy can promote employment.

Abstract: In order to realize the integration and sharing for multi-source marine data, the paper took the visualization application of the multi-source marine environment data as an example to discuss the realization way of the data’s integration and sharing. By encapsulating the marine environment data and its application model to web services, we constructed a multi-source marine environment data applying platform system framework through internet. The system can shield the data isomerism and the application environment isomerism, and realize the integration and sharing for the multi-source marine environment data. At the same time the distributed structure of the system can raise its flexibility and expansibility. So the establishment of the system proves the feasibility of web service in multi-source ocean environment data’s integration and sharing.

Abstract: Carbon fiber(CF) and Kevlar fiber(KF) were used as reinforcing agents to fill Ekonol(EK) respectively. Mechanical and tribological properties of composite systems were tested. When CF was used as the EK reinforced filler, the mechanical properties of EK composites couldn’t be enhanced obviously, and the tribological properties were reduced. When KF was filled in EK matrix, it could greatly improve the impact strength of EK composite by reducing crack formation and inhibiting crack propagation. The KF/EK composite has good tribological properties. It keeps the high friction low wear performance advantage of EK, and solves its problem of forming difficulty. In EK composite, KF plays the role of reinforcing agents and friction modifier at the same time, and then it is a kind of excellent EK reinforced filler.

Abstract: The paper introduces some effective methods to solve the problems of solid modeling with the software of AutoCAD. Make good use of views to avoid converting UCS frequently and set up proper layers aimed to the building or structure and draw solid in order to control the display of different parts of solid. According to analysis and research on 3D solid model, the authors also point out other techniques, such as the skills about Boolean Calculation and conclude that different operation sequence produces different result and sometimes don't need to input a data and also complete to cut of solid. These skills are helpful to make solid model.

Abstract: In hydropower station in the operation of total with hydraulic transient process of the power station on the transition process analysis and calculation is quite important. This paper introduces the today's advanced scientific computing software MATLAB, and using the software of the Zipingpu hydropower station hydraulic transients from the mathematical model and calculation simulation etc is analyzed and calculated with research, in order to seek appropriate power operation mode, unit close regularities. For power station and water system design optimization, safe operation, provides the basis.

Abstract: In vehicular ad hoc networks, uncooperative behaviors will impact the reliability of comfort applications, as well as drivers’ decisions, and even invoke serious traffic accidents. In this paper, we propose a novel game incentive scheme to stimulate cooperation among vehicle nodes, consider selfish nodes’ expectations to future payoff and their long-term desires for profit, and show analytically the three incentive-compatible conditions under which selfish nodes will be deterred from cheating by the subsequent punishments. We also discuss the impact on selfish nodes’ behavior, which is caused by their willingness for future collaboration, the parameter values of punishment mechanism and the variation of network load. Simulation results show that, the increase of network load and the deterioration of node’s future profit expectation will motivate nodes toward self-interested action, but our scheme can neutralize this tendency by the careful configuration of punishment parameters, and have favorable incentive effect.

Abstract: The employing of multimedia in teaching has already become widespread because of its many advantages. In order to avoid boredom and aesthetic fatigue of students, better play its own advantages as well as improve the efficiency and effectiveness of teaching, this paper tends to offer multi methods to realize humanized design in multimedia teaching.

Abstract: The key for Autonomous Underwater Vehicle (AUV) to implement target pursuit is to design high performance guidance law. The globose reference frame is adopted, and equations for 3-D relative motion between AUV and the target are built. Then the H_∞ theory is used, and a new AUV nonlinear H_∞ guidance law is obtained by solving Hamilton-Jacobi inequation. Simulation is taken on to verify the performance of H_∞ guidance law. And the results show that the H_∞ guidance law can help AUV overtake the target in less time, and the azimuth and pitching angle of the target line of sight are always staying at the initial numerical values. Furthermore, the normal load decreases to zero gradually. So the guidance law is effective for AUV to pursuit target.

Abstract: The central region is a large agricultural area in China, while the agricultural product logistics is on the stage of traditional logistics. This greatly restricts and influences the agriculture competitiveness and economic development of central China. Starting from the definition and analysis of the meaning of modern agricultural logistics, it discusses the significance and the need of the development of modern agricultural products logistics, and focuses on the suggestions and strategies to develop the modern agricultural logistics in central China. It is to provide a meaningful reference to enhance the level of the agricultural products logistics and realize the agricultural economic advantages of central China.

Abstract: In the production scheduling model based on the traditional basis, from the multi-multi-objective optimization modeling to genetic algorithm’s optimization, introduces incentive mechanisms and the psychological factors, presents a paper-making enterprise based on genetic algorithm optimization Scheduling model. a simulation study and comparison of algorithms to verify the feasibility of the program and solve the problem of scheduling the order of optimization.
