In multiple scale method, the independent variable will be replaced by several variables, each with a scaled down speed of variation. Replacing the independent variable, makes a nonlinear ordinary differential equation to be transformed to a series of linear partial differential equations. Combination of the solutions of the linear partial differential

Abstract In this chapter we apply the multiple-scale method to the study of problem (6.1). The method is presented in Section 7.1 and a formal asymptotic expansion for u ε is obtained. The goal of Section 7.2 is to prove the error estimate stated in Theorem 6.3.

A HIGHER ORDER METHOD OF MULTIPLE SCALES
Journal of Sound and Vibration, 1997Summary: Perturbation methods are often applied in the analysis of weakly nonlinear dynamic systems. The method of multiple scales, for instance, is a common choice. \textit{Z. Rahman} and \textit{T. D. Burton} [ibid. 133, No. 3, 369--379 (1989; Zbl 1235.70099)] proposed a version of the method of multiple scales which can be used to determine the ...

On the Reconstitution Problem in the Multiple Time-Scale Method
Nonlinear Dynamics, 1999The authors consider general systems of the form \(\ddot q+F(q, \dot q,t;\mu)=0\), where \(\mu\) is a vector containing small physical quantities, or small deviations from the critical values of other parameters. A perturbation parameter \(\varepsilon\) is introduced by the equation \(\mu= \varepsilon \widehat\mu\), \(\widehat\mu= O(1)\), then the ...

An Alternative Example of the Method of Multiple Scales
SIAM Review, 2000Summary: An alternative example of the method of multiple scales is presented. This example arises in the study of the classical heat equation with a slowly varying flux imposed at one end. The module presents introductory ideas about dimensionless variables, multiple-scale expansions, and scaling of the dependent variable.

A Method of Multiple Scales for Integral Equations
Journal of the Physical Society of Japan, 1981A new method is proposed for the purpose of analysing the system of weakly nonlinear integral equations. The essence of this method consists in expanding the integral operator in powers of e : \(\int _{0}^{t} \text{d}t= \sum _{n=0}^{N} \varepsilon ^{n} \text{I}_{n} + O(\varepsilon ^{N+1}),i\) where N is a positive integer, e is a small parameter ...

Multiple scales methods in meteorology
2010With emphasis on meteorological applications, we discuss here the fluid dynamical fundamental governing equations, their nondimensionalization including the identification of key nondimensional parameters, and a general approach to meteorological modelling based on multiple scales asymptotics.

Multiple scale finite element methods
International Journal for Numerical Methods in Engineering, 1991AbstractNew temporal and spatial discretization methods are developed for multiple scale structural dynamic problems. The concept of fast and slow time scales is introduced for the temporal discretization. The required time step is shown to be dependent only on the slow time scale, and therefore, large time steps can be used for high frequency problems.
