Improved solution for solitary waves in arteries

Journal of Mathematical Biology, 1999
Nonlinear waves are investigated numerically by a direct analysis of the field equations, thereby establishing the magnitude of the errors inherent in the commonly used reductive perturbation technique. The method is also applied beyond the long-wave approximation and a comparative assessment of the results obtained is presented.

Relativistic Solitary-Wave Solutions of the Beat-Wave Equations

Physical Review Letters, 1986
The relativistic equations governing the nonlinear interaction of two light waves and a Langmuir wave are shown to admit two classes of solitary-wave solutions. Temporal solitary waves propagate at speeds greater than the speed of light and carry no information.

Solitary Waves Solutions of a Nonlinear Schrödinger Equation

2003
The aim of this note is to prove the existence of standing waves solutions of the following nonlinear Schrodinger equation $$ i\frac{{\partial \psi }} {{\partial t}} = - \Delta \psi + V(x)\psi + \varepsilon N(\psi ), $$ where NM is a nonlinear differential operator.

A discretized solution for the solitary wave

Journal of Computational Physics, 1974
A successive correction technique, based on generalization to n dimensions of Newton's process for finding zeros of a real function of a real variable, is employed to solve two-dimensional steady-state potential flows with free surface and gravity.

Analyticity of Solitary-Wave Solutions of Model Equations for Long Waves

SIAM Journal on Mathematical Analysis, 1996
Summary: It is shown that solitary-wave solutions of model equations for long waves have an analytic extension to a strip in the complex plane that is symmetric about the real axis. The classes of equations to which the analysis applies include equations of Korteweg-de Vries type, the regularized long-wave equations, and particular instances of ...

Solitary wave solutions of nonlinear wave equations

American Journal of Physics, 1992
A method is proposed for obtaining traveling-wave solutions of nonlinear wave equations that are essentially of a localized nature. It is based on the fact that most solutions are functions of a hyperbolic tangent. This technique is straightforward to use and only minimal algebra is needed to find these solutions.

Fundamental solution of nuclear solitary wave

Energy Conversion and Management, 2012
Abstract This paper deals with the problem of asymptotic breeding/burning waves during long term nuclear fission processes. The uranium–plutonium (U–Pu) conversion cycle is considered under fast spectrum conditions. A one-group diffusion equation coupled with burn-up equations is set up.
