Based on these models, the concepts and the quanti- tative expressions of road feel, sensitivity, and operation stability of the steering are introduced. Then, according to constrained optimization features of multi-variable function, a genetic algorithm is designed. Making the road feel of the steering as optimization objective, and operation stability and sensitivity of the steering as constraints, the system parameters are optimized by the genetic and the coordinate rotation algorithms. Simulation results show that the optimization of the novel EPS system by the genetic algorithm can effectively improve the road feel, thus providing a theoretical basis for the design and optimization of the novel EPS system.展开更多

To reemerge the spirit of The Scarlet Letter,Which is considered as Hawthorne's religious view and humanistic feeling,the death of two heroes in this novel should be analyzed in the aspects of religion and human nature,and even in the aspects of the vocabulary,theme and mental world of main characters.展开更多

Austen proclaims that feeling should be governed by reason in Sense and Sensibility and that reason should be compatible with feeling in Persuasion. This paper attempts to explore romantic tendency in Austen's works according to the comparison and contrast between her two novels. Through comparison and contrast, we can see the transformation of Marianne from a lady of sensibility to a sensible lady and the growth of Anne into a lady with romance.展开更多

As a freelance writer and reviewer, she achieved great success with some short stories.One of her most famous masterpieces is "A Dill Pickle", on which this article comments. "A Dill Pickle" shows the extent to which romantic love is dependent upon circumstances and the convergence of certain character traits at a particular time. The story artfully and subtlety points up the heroine’ s sensitivity and the man’ s insensitivity to others - their feelings, attitudes and inner motivations.展开更多

The concepts and quantitative expressions of the steering road feel, steering sensibility, and steering operation stability are introduced. Based on quality engineering theory, the optimization algorithm is proposed by integrating the Monte Carlo descriptive sampling, elitist non-dominated sorting genetic algorithm （NSGA-II） and 6-sigma design method. With the steering road feel and the steering portability as optimization targets, the system parameters are optimized by the proposed optimization algorithm. The simulation results show that the system optimized based on quality engineering theory can improve the steering road feel, guarantee steering stability and steering portability and thus provide a theoretical basis for the design and optimization of the novel electric power steering system.展开更多
