In this paper, we investigate the impact of 2010 World Expo on the economic growth of Shanghai via a dynamic VAR model. In this model we take the fixed assets investment, new employment population, new tourist income as influence variables, and take GDP (Gross Domestic Product) and House Hold Consumption as influence object. By establishing VAR model (Vector Autoregressive Model) and utilizing impulse...
Based on mixed fault for actuator, this paper is concerned with reliable control problems for systems with time delay. Mixed fault is discrete fault model and continuous fault model coexist in a system. The proposed method not only quotes the general model but also combines reliable control with switched system, making full use of advantages of both systems. It can save much energy for reliable controller...
Dredging simulation is of great significance to the development of dredging engineering technology of harbor, waterway, rivers, lakes, etc. The design and implement of the dredging simulation system are introduced. The modeling and key techniques for the virtual reality of construction site, the movement of dredge vessel, the soil cutting of cutter, and the hydraulic transport of sand in a pipeline,...
