A Bayesian nonlinearity test for threshold moving average models [PDF]
, 2010 We propose a Bayesian test for nonlinearity of threshold moving average (TMA) models. First, we obtain the marginal posterior densities of all parameters, including the threshold and delay, of the TMA model using Gibbs sampler with the Metropolis ...

International Journal of Bifurcation and Chaos, 1997 The objectives and some basic methods of numerical bifurcation analysis are described. Several computational examples are used to illustrate the power as well as the limitations of these techniques. Directions in which further algorithmic and software development is desirable are also discussed.

Residual component analysis of hyperspectral images - Application to joint nonlinear unmixing and nonlinearity detection [PDF]
, 2014 This paper presents a nonlinear mixing model for joint hyperspectral image unmixing and nonlinearity detection. The proposed model assumes that the pixel reflectances are linear combinations of known pure spectral components corrupted by an additional ...

Second order nonlinear frequency generation at the nanoscale in dielectric platforms
Advances in Physics: X, 2022 Nonlinear frequency generation at the nanoscale is a hot research topic which is gaining increasing attention in nanophotonics. The generation of harmonics in subwavelength volumes is historically associated with the enhancement of electric fields in the

Nonlinearity detection in hyperspectral images using a polynomial post-nonlinear mixing model [PDF]
, 2012 This paper studies a nonlinear mixing model for hyperspectral image unmixing and nonlinearity detection. The proposed model assumes that the pixel reflectances are nonlinear functions of pure spectral components contaminated by an additive white Gaussian

Corrigendum: Higher order averaging theory for finding periodic solutions via Brouwer degree (2014 Nonlinearity 27 563) [PDF]
, 2014 [No abstract available]In this paper we deal with nonlinear differential systems of the form x'(t) = Sigma(k)(i=0) epsilon(i) F(i()t,x) + epsilon(k+1) R(t,x,epsilon), where F-i : R x D -> R-n for i = 0, 1, ... , k, and R : R x D x (-epsilon 0, epsilon 0).

Dizhen xuebao, 2019 为了分析总谐波失真度和互调失真度这两个非线性指标的测试方法、输入信号幅值等变化对其测试结果的影响，本文从总谐波失真信号、互调失真信号的产生原理出发，详细地给出了两种指标的测试方法、数据处理方法及相关影响分析，并通过实际应用中不同类型的输入信号进行了总谐波失真度和互调失真度试验。测试结果表明：信号模式和信号幅值对总谐波失真度的影响显著；输入信号幅值对互调失真度的影响较大；输入信号的频率变化对两指标的测试结果无影响。本研究进一步细化了地震数据采集器性能指标的标准化测试方法 ...

Biometrika, 1988 The paper presents at first an outline of the basic linear algebra of the classical biplot. Let X be an \(n\times p\) matrix containing numerical information on p variables for each of n samples. The graphical representation of X in a biplot is based on the singular value decomposition \(X=UGV'\), where U and V are \(n\times n\) and \(p\times p ...
