Electromagnetic Nondestructive Testing by Perturbation Homotopy Method [PDF]
Mathematical Problems in Engineering, 2014 Now electromagnetic nondestructive testing methods have been applied to many fields of engineering. But traditional electromagnetic methods (usually based on least square and local iteration) just roughly give the information of location, scale, and quality.

HOMOTOPY-PERTURBATION METHOD [PDF]
, 2008 The homotopy perturbation method (HPM) is employed to compute an approximation to the solution of the system of nonlinear differential equations governing on the problem. It has been attempted to show the capabilities and wide-range applications of the homotopy perturbation method in comparison with the previous ones in solving heat transfer problems ...

Homotopy Perturbation Method for Solving Reaction‐Diffusion Equations [PDF]
Mathematical Problems in Engineering, 2008 The homotopy perturbation method is applied to solve reaction‐diffusion equations. In this method, the trial function (initial solution) is chosen with some unknown parameters, which are identified using the method of weighted residuals. Some examples are given.

Homotopy Perturbation Method for Brachistochrone Problem [PDF]
Mathematics and Statistics, 2013 The most famous classical variational principle is the so-called Brachistochrone problem. In this work, Homotopy perturbation method (HPM) is applied to the Brachistochrone problem that arises invariational problems. The results reveal the efficiency and the accuracy of the proposed method.

He’s multiple scales method for nonlinear vibrations
Journal of Low Frequency Noise, Vibration and Active Control, 2019 He’s multiple scales method is a couple of the homotopy perturbation method and the multiple scales technology in the classic perturbation method. This method has been proved to be a powerful mathematical tool to various nonlinear equations, and it is ...
