Nonsymmetrical, Nonlinear Aerospace Alternators on Nonlinear Loads

IEEE Transactions on Aerospace and Electronic Systems, 1975
A two-dimensional numerical analysis of the cross section of a homopolar inductor alternator supplying a rectifier load is developed. Besides the effects of the nonlinearities of the magnetic materials, the eddy currents induced in the rotor by the nonlinear load are considered.

Phragmen–Lindelof alternative in nonlinear viscoelasticity

Nonlinear Analysis: Theory, Methods & Applications, 1998
This paper investigates the spatial behaviour of the solution to a boundary-initial value problem for a nonlinear partial differential equation. First, the author establishes the spatial decay estimates, and then obtains an upper bound on the amplitude term.

An Alternative Approach to Nonlinear Instabilities in Hydrodynamics

Studies in Applied Mathematics, 1985
The conventional theoretical methods used in the study of nonlinear hydrodynamic instabilities are known to suffer from severe amplitude limitations. In this paper a modified asymptotic theory is developed which is more general and less restrictive. Such an approach may be relevant to many nonlinear instability phenomena.

Alternating least squares in nonlinear principal components

WIREs Computational Statistics, 2013
Principal components analysis (PCA) is probably the most popular descriptive multivariate method for analyzing quantitative data with ratio and interval scale measures. When applying PCA to nominal and ordinal data, the data are processed by a method such as optimal scaling, which nonlinearly transforms nominal and ordinal data into quantitative data ...

Nonlinear alternative theorems and nondifferentiable programming

Zeitschrift für Operations Research, 1984
The paper contains two main conclusions. In the first place there is a nonlinear Farkas-type theorem in which the objective function f(x): \(X\to {\mathbb{R}}\), \(f(0)=0\), is convex and continuous at 0 and the constraint g(x): \(X\to Y\) is S-sublinear, weakly \(S^*\)-lower semicontinuous with respect to a closed convex cone \(S\subset Y\).

Nonlinear effects in alternating-gradient synchrotrons

Annals of Physics, 1958
Abstract Nonlinear effects in alternating-gradient synchrotrons are responsible for resonances in the betatron-oscillation mechanism over and above those which arise in linear theory. These effects are here investigated by means of a perturbation procedure which leads directly to practical formulas.

Alternating Direction Methods for Nonlinear Time-Dependent Problems

SIAM Journal on Numerical Analysis, 1977
A convergence rate of $O((\Delta t)^2 + h^2 )$ is established for some alternating direction methods for the approximate solution of a nonlinear parabolic partial differential equation and of a nonlinear second order hyperbolic partial differential equation.

Nonlinear alternating current conduction in polycrystalline manganites

Journal of Applied Physics, 2014
The real part of ac conductance Σ(T, f) of yttrium-doped mixed-valent polycrystalline manganite systems La1−x−yYyCaxMnO3 with x = 0.33 and 0.05 and y = 0.07 and iron doped LaMn1−xFexO3 with x = 0.15 is measured as a function of frequency f by varying zero-frequency Ohmic conductance Σ0 by T.
