Based on nonlinear fitting, the revised model brings out more evident improvement of the linear model proposed by Solow et al. (1987). Both theoretical deduction and case calculation show that our version can search the turning point and period accurately and objectively. In particular it is fit for computer exploring the turning points in long-range records from stations covering a large area, thus avoiding subjective judgement by a usual drawing method.展开更多

The most prominent thing brought by urbanization is change in traditional folklore. In contemporary China, urbanization is accompanied by modernization. Under the influence of consumer culture and the modern media, traditional rural folklore is gradually evolving into urban mass culture. Additionally, it is being spread by a big wave of informatization, characteristic of the digital revolution. Traditional rural customs are always important contents of folklore study, but nowadays and in the future, the research focus of Chinese folklore studies needs to be adjusted. At the same time, individual folklore study needs to be turned into holistic culture study under that specific context.展开更多

In various stability tests, different models with different tires from the market were tested. A successful outcome of this research would generate an efficient tire selection process and improve the handling of a trailer attached to a vehicle while maximizing fuel efficiency. In this study, different accurate tire models using the magic formula were developed in vehicle dynamics modelling and simulation software. These models were then simulated on on-road conditions to predict vehicle and trailer behaviour under different conditions within the software. Two distinct tests were conducted, the J-Turn test and the Double Lane change test. The results of these tests were used to evaluate the handling characteristics and decide on a better tire size for the trailer attached to the vehicle.展开更多
