On weighted total least squares adjustment for solving the nonlinear problems

open access: yesJournal of Geodetic Science, 2014
In the classical geodetic data processing, a non- linear problem always can be converted to a linear least squares adjustment. However, the errors in Jacob matrix are often not being considered when using the least square method to estimate the optimal ...

Nonlinear short-run adjustments between house and stock prices in emerging Asian regions [PDF]

open access: yesPanoeconomicus, 2018
This study uses the powerful nonparametric cointegration test to examine whether nonlinear cointegration exists between prices of used houses and corresponding stock markets in China and the four Asian Tigers.

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 ...

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 ...

Learning fuzzy inference systems using an adaptive membership function scheme [PDF]

open access: yes, 1996
An adaptive membership function scheme for general additive fuzzy systems is proposed in this paper. The proposed scheme can adapt a proper membership function for any nonlinear input-output mapping, based upon a minimum number of rules and an initial ...

Nonlinear error correction, asymmetric adjusment and cointegration [PDF]

open access: yes, 1991
This paper has three main components. First, it outlines a model of nonlinear error correction (NEC) in which the linear error correction term a'Xt (the vector time series Xt is cointegrated, a is the cointegrating vector) is replaced by the nonlinear ...

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.
