Homotopy perturbation method coupled with the enhanced perturbation method [PDF]

Journal of Low Frequency Noise, Vibration and Active Control, 2018
The enhanced perturbation method is used to improve a governing equation to a higher order, followed by the classic perturbation method. This paper adopts the basic idea of the method to construct a homotopy equation with a higher order. The results show that this modification of the homotopy perturbation method leads to a very high accuracy of the ...

Asymptotic solution of the mathematical model of nonlinear oscillations of absolutely elastic inextensible weightless string

Nonlinear Analysis, 2010
The mathematical model of nonlinear oscillations of weightless string is analyzed. To find an asymptotic solution of the problem, uniformly valid in a long interval of time, an averaged system of integral differential equations has been constructed.

A remark on the similarity and perturbation problems [PDF]

, 2013
In this note we show that Kadison's similarity problem for C*-algebras is equivalent to a problem in perturbation theory: must close C*-algebras have close ...

Influence of the Motion of a Spring Pendulum on Energy-Harvesting Devices

Applied Sciences, 2021
Energy harvesting is becoming more and more essential in the mechanical vibration application of many devices. Appropriate devices can convert the vibrations into electrical energy, which can be used as a power supply instead of ordinary ones. This study

Kruskal's Perturbation Method [PDF]

Journal of Mathematical Physics, 1970
A general method for eliminating the angle variable from the equations of a perturbed periodic motion and for deriving an ``adiabatic invariant'' J has been given by Kruskal and, for a special class of Hamiltonian systems, McNamara and Whiteman have shown (to order ε2) that J is related to a set of invariants I obtained from the expansion of Poisson ...

The vibration of nanobeam resting on elastic foundation using modified couple stress theory

Tehnički Glasnik, 2018
In this paper, the vibration of nanobeams resting on the Winkler foundation is proposed using the modified couple stress theory. Hamilton’s principle is utilized to construct the governing equations.
