In order to improve the road safety of highway in the highlands, taking traffic engineering, psychology and other theories as the foundation, the paper investigates the road alignment, operating speed of passenger cars and the drivers' psychological and physiological reactions of the Qinghai-Tibet Highway, explores the relationship between the operating speed of passenger cars and the drivers' psychological...
During the previous work of this paper, the change of a maneuvering target state and the nonlinear of maneuvering target system model are considered, and IMMPF (Interacting Multiple Model Particle Filter) is used to state estimation of the maneuvering target. Then some simulations have been done. The results showed that the idea is feasible, and the single GPS (Global Positioning System) location...
Stand age is the average age of trees in the stand. In this paper, the back propagation (BP) artificial neural network, the projection pursuit regression (PPR) artificial neural network and the multiple stepwise regression anatomic models were introduced to predict the nonlinear relation between the natural stand age and the stand factors. At the same time, the author contrasted the forecasting results...
