The Adomian method is wiedly used in approximate caculation, its main demerit is very difficult and complex to calculate Adomian,s polynomial. This paper introduces the homotopy perturbation method for overcoming comletely the disadvantage...

In this paper, we use He’s homotopy perturbation method (HPM) for solving linear programming (LP)

problems. By applying HPM for this class of problems, optimal solutions of a primal LP problem and its

corresponding dual problem can...

Abstract

In this paper, we apply a new modified homotopy perturbation method to find exact solutions for nonlinear integral equations. A

reliable modification of the homotopy perturbation method is proposed, and the modified method...

damper consisting of a pendulum and an elastic barrier. Our model incorporates Hertzian contact between the spherical steel pendulum and the barrier. In next step, due to the strong non-linearity of the model, Homotopy Perturbation and iteration...

In this paper, the homotopy perturbation method (HPM) is employed to solve the porous media equation. The particular exact solutions of the porous media equation that usually occurs in nonlinear problems of heat and mass transfer are obtained using...

Nonlinear convective–radiative cooling equation, nonlinear heat equation with

cubic nonlinearity and the shear deformation of sandwich beams are used as ...

In this paper, we use modified homotopy perturbation method(MHPM) for solving the systemof linear and non- linear Volterra integral equations. Comparisons are made between MHPM and well- known Adomain decomposition method (ADM) abd Runge- Kutta...

the behaviour of a kind of impact dampers. Our model incorporates Hertzian contact between the impact mass and the barrie. In next step, due to the strong non-linearity of the model, Homotopy Perturbation method is used to solve the governing equation...
