Effect of Nonlinear Soil Model on Seismic Response of Slopes Composed of Granular Soil

open access: yesAdvances in Civil Engineering, 2020
A series of two-dimensional finite element analyses are performed to simulate the seismic response of slope composed of granular soil. Four sets of input parameters for the nonlinear soil model are used to fit the reference the shear modulus reduction ...

Nonlinear Systematic Distortions Compensation in Satellite Images Based on an Equivalent Geometric Sensor Model Recovered From RPCs

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The rational polynomial function is widely accepted as the preferred sensor model for high-resolution satellite imagery (HRSI). However, satellite images and their associated rational polynomial coefficients (RPCs) often suffer from nonlinear systematic ...

Covariate-adjusted nonlinear regression

open access: yesThe Annals of Statistics, 2009
In this paper, we propose a covariate-adjusted nonlinear regression model. In this model, both the response and predictors can only be observed after being distorted by some multiplicative factors. Because of nonlinearity, existing methods for the linear setting cannot be directly employed.

Nonlinear Error Correction Models [PDF]

open access: yes, 2002
The relationship between cointegration and error correction (EC) models is well characterized in a linear context, but the extension to the nonlinear context is still a challenge.

Stabilizing high-order discrete dynamical systems by a lagged adaptive adjustment mechanism

open access: yesDiscrete Dynamics in Nature and Society, 2002
A lagged adaptive adjustment mechanism has been developed to stabilize a high-order discrete system. Theoretical proofs and computer simulations have been provided to show the effectiveness and efficiency of this new mechanism in practice.
