A modified method, which combines chaos optimization method and simulated annealing algorithm, is proposed to calculate the Jiles-Atherton (J-A) model parameters. The new method is validated by comparing its computation results with measurement data. Then, the validated J-A model is used in numerical modeling of Epstein frame, and the numerical results are found to be in good agreement with measurement...
The dynamical theory of chaos is the new analysis method of study on the exchange rate undulation in the foreign exchange market. In order to study the chaos behavior of the Euro exchange rate, this paper put the purchase price of the RMB to the Euro as the sample and analyzes the nonlinear character of the Euro exchange rate. This paper figures out the Hurst exponent by the R/S analysis and confirms...
