In the process of development of measure instrument used to measure stiffness and mini lag angle of minitype torsion pole, the problem in precise measurement of mini lag angle of minitype torsion pole was successfully solved(the measure precision reached 0 1″).
在微型扭杆刚度及小滞后角测量仪的研制过程中 ,成功地解决了微型扭杆小滞后角的精密测量问题 ,测量精度达 0 。
Based on the inspecting and discriminating the nonlinearities structure of the exchange rate system by using the method of surrogate data,the optimal lag periods for each specific exchange rate series was computed,then we adopt both the structure of multi-layer perceptrons(MLP) and recurrent neural networks(RNN2) to build the homogenous ANN model.
在利用替代数据方法检验和判别汇率系统具有非线性结构的基础上,识别了各具体汇率序列的最优滞后期组合,并分别采用了多层感知机(MLP)和层反馈网络(RNN2)结构构建同质神经网络模型,从三个方面对比分析了模型群在不同参数条件下的预测效果。
