Nonlinear alternating current responses of graded materials [PDF]

open access: yesPhysical Review E, 2004
When a composite of nonlinear particles suspended in a host medium is subjected to a sinusoidal electric field, the electrical response in the composite will generally consist of alternating current (AC) fields at frequencies of higher-order harmonics.

Nonlinear alternating current responses of dipolar fluids [PDF]

open access: yesPhysical Review E, 2004
The frequency-dependent nonlinear dielectric increment of dipolar fluids in nonpolar fluids is often measured by using a stationary relaxation method in which two electric fields are used: The static direct current (DC) field of high strength causing the dielectric nonlinearity, and the probing alternating current (AC) field of low strength and high ...

Multiplicity of Positive Periodic Solutions of Singular Semipositone Third-Order Boundary Value Problems

open access: yesBoundary Value Problems, 2008
We establish the existence of multiple positive solutions for a singular nonlinear third-order periodic boundary value problem. We are mainly interested in the semipositone case.

An Alternative Approach to Integrable Discrete Nonlinear Schrödinger Equations [PDF]

open access: yesActa Applicandae Mathematicae, 2013
The authors point out some problems with the standard linear counterpart to the (matrix) integrable discrete nonlinear Schrödinger equation, and propose an alternative linear counterpart in order to overcome these problems. Thus they replace the usual finite difference approximation (1.2) of the Zakharov-Shabat system -- where the derivative with ...

On the Nonhomogeneous Fourth-Order p-Laplacian Generalized Sturm-Liouville Nonlocal Boundary Value Problems

open access: yesDiscrete Dynamics in Nature and Society, 2012
We study the nonlinear nonhomogeneous n-point generalized Sturm-Liouville fourth-order p-Laplacian boundary value problem by using Leray-Schauder nonlinear alternative and Leggett-Williams fixed-point theorem.

Alternative methods for solving nonlinear two-point boundary value problems

open access: yesOpen Physics, 2018
In this sequel, the numerical solution of nonlinear two-point boundary value problems (NTBVPs) for ordinary differential equations (ODEs) is found by Bezier curve method (BCM) and orthonormal Bernstein polynomials (OBPs). OBPs will be constructed by Gram-

Existence theory for nonlocal boundary value problems involving mixed fractional derivatives

open access: yesNonlinear Analysis, 2019
In this paper, we develop the existence theory for a new kind of nonlocal three-point boundary value problems for differential equations and inclusions involving both left Caputo and right Riemann–Liouville fractional derivatives.

A nonlinear alternating direction method [PDF]

open access: yesMathematics of Computation, 1969
An alternating direction iteration method is formulated, and convergence is proved, for the solution of certain systems of nonlinear equations. The method is applied to a heat conduction problem with a nonlinear boundary condition.
