At first,risk-neutral probabilities of option pricing were obtained which with asymmetrical multinomial model of two assets,then the American option price of two assets were gotten,which volatility followed Markov process.

OFDM blind channel estimation based on polynomial models;

To improve the precision of short stroke control in hot mill, the broken line model is converted into the slick curve model,a polynomial model and a RBF neural network model are studied,which have been simulated and applied to online controlling.

Using the polynomial model as the dynamics model of magneto-rheological damper,the bad effect of the damping force jump with the "on-off" semi-active control on vibration acceleration of vehicle sprung mass is investigated.

With the introduction of the concept of polynomial tree,the article studies the construction problem of polynomial basis from a broader sense of perspective.

In the first chapter, the concept of polynomial tree is proposed in order to present a concrete thread of thought for the structure of basis The second chapter mainly deals with the transplantation of polynomial trees.
