Nonlinear Computation will provide a framework for the computational science and engineering of the future. Topics such as bifurcation and chaos, and methods such as continuation and branch switching, and features such as stability and sensitivity are basic ingredients in the attempt to understand our world. Nonlinear Computation is indispensable when

SIAM Journal on Matrix Analysis and Applications, 1999
The nonlinear eigenvalue problem \(A(\lambda)v=0\) with holomorphic matrix-valued function \(A(\lambda)\) defined on a domain \(\Omega\subset\mathbb{C}\) is considered. The author suggests a method for solving this problem connected with the calculation of the derivatives of the function \(x(\lambda)={A(\lambda)}^{-1}b,\) where \(b\) is a given vector.

Combination tones (CT's) produced by two-tone stimuli (f1 and f2) at relatively low sound levels contradict the classical view that auditory mechanics is an essentially linear process that suffers significant percentage distortion only at high sound levels.

Identification of nonlinear systems with hard nonlinearity
2018 5th International Conference on Control, Decision and Information Technologies (CoDIT), 2018The problem of identifying nonlinear systems is proposed in the presence of hard nonlinearity. Presently, the nonlinear system is structured by Wiener-Hammerstein systems consist of a series connection including a nonlinear element sandwiched with two linear subsystems.

DESIGN OF NONLINEAR CONTROLLERS FOR NONLINEAR PLANTS
IFAC Proceedings Volumes, 1990Abstract The paper describes three methods for designing nonlinear phase lead/lag controllers to be used in cascade with nonlinear plants to provide closed loop responses which are essentially amplitude independent. The approach requires amplitude dependent frequency response descriptions of the nonlinear plants, makes use of the describing function ...

Nonlinear Models of Clinical Judgment: Communal Nonlinearity and Nonlinear Accuracy
Psychological Science, 2001Despite our intuition that representative expert judgments are highly nonlinear, previous studies have shown only little, if any, nonlinearity in such judgments. The current study presents a method for assessing nonlinearity in judgment that is based on estimating communal nonlinearity—the systematic nonlinearity shared by the community of judges. The

Discrete nonlinear systems: on the admissible nonlinear disturbances
Journal of the Franklin Institute, 2001Consider the linear nominal discrete system \[ x_{i+1}= Ax_i,\quad y_i= Cx_i,\quad x_0\in \mathbb{R}^n\tag{1} \] and a perturbed form \[ x^\xi_{i+1}= Ax^\varepsilon_i+ Be_i+ g(\beta_i) f(x^\xi_i),\;x^\xi_0= x_0+ w,\;y^\xi_i= Cx^\xi_i,\tag{2} \] where \(e_i\), \(\beta_i\), \(w\) are some disturbance parameters. The disturbance \((w,(e_i),(\beta_i))\) is

Identification of nonlinear LFR systems with two nonlinearities
2013 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2013When identifying a system (e.g. mechanical, electrical or chemical) based on inand output measurements and without physical knowledge, an engineer faces many choices. First of all, there exist standard linear models, but when those do not sufficiently well describe the data, nonlinear models should be considered.

Nonlinear elliptic equations with singular nonlinearities
Asymptotic Analysis, 2013In this paper we study nonlinear elliptic boundary value problems with singular nonlinearities whose simplest example is −div (|∇u|p−2∇u)=f/uγ in Ω, u=0 on ∂Ω, where Ω is a bounded open set in RN (N≥2), γ>0 ...
