Variation of hydraulic gradient in nonlinear finite strain consolidationXIE Xin-yu(谢新宇)1, 2, 3, HUANG Jie-qing(黄杰卿)1, 2, 3, WANG Wen-jun(王文军)2, LI Jin-zhu(李金柱)2(1. Research Center of Coastal... is studied for decades. In the consolidation field, hydraulic gradient is yet to be investigated as an important hydraulic variable. So, the variation of hydraulic gradient in nonlinear finite strain......
prices was studied using the nonlinear Granger causality test and the dynamic conditional correlation-generalized autoregressive conditional heteroskedastic (DCC-GARCH) model. The results indicate...; nonlinear Granger causality test; DCC-GARCH model 1 Introduction The Renminbi (RMB) formally entered the special drawing rights (SDR) basket as its fifth member on October 1, 2016, which put it ahead......
, the amplitudes of the components are far less than the major part, so in some cases the nonlinear terms can be ignored to predigest the model. If a linear fitting model is given as , the following frequency... of the input current and output displacement of the linear and nonlinear models. 3 ESTABLISHED MODEL 3.1 Modeling of actuator Considering the working principle of a magnetostrictive......
precipitation process. In order to control the decomposition temperature precisely, a nonlinear dynamic model of the precipitator equipped with a plate heat exchanger in alumina tri-hydrate precipitation was built by mechanism analysis and parameter estimation, and the accuracy of the model was proved by the simulation with actual process data. A nonlinear model predictive control (DP-NMPC......
that the modeling approaches and valuation model of the nonlinear evaluation function are more practical than the weighting model. Key words: material life cycle assessment; life cycle impact assessment... function consequentially is a multi-independent-variable function. In general, the evaluation function is divided into linear function and nonlinear function. 2.1 Model of linear evaluation function......
of the nonlinear self-correction function of the measurement model, it can better reflect the evolution path of product quality whose actual trend is time nonlinear, and can enhance the accuracy of the measurement of the export product quality significantly. Key words: export product; quality index; measurement model; nonlinear self-tuning model 机电类出口产品质量很早就受到了国外学者专家的关注[1].最初由于数据的不可获得性,对机电类出口产品质量的研究一般停留在理论研究阶......
