An Extension of the Optimal Homotopy Asymptotic Method to Coupled Schrödinger-KdV Equation [PDF]
International Journal of Differential Equations, 2014 We consider the approximate solution of the coupled Schrödinger-KdV equation by using the extended optimal homotopy asymptotic method (OHAM). We obtained the extended OHAM solution of the problem and compared with the exact, variational iteration method (

Applications of Optimal Homotopy Asymptotic Method (OHAM) to Tenth Order Boundary Value Problem
Lecture Notes in Civil EngineeringAbstractThe aim of this paper is to apply the Optimal Homotopy Asymptotic Method (OHAM), a semi-numerical and semi-analytic technique for solving linear and nonlinear Tenth order boundary value problems. The approximate solution of the problem is calculated in terms of a rapidly convergent series.

Viscoelastic Flow and Heat Transfer over a Non-Linearly Stretching Sheet: OHAM Solution
Journal of Applied Fluid Mechanics, 2016 In this paper the viscoelastic flow and heat transfer over a non-linearly stretching sheet with the power law velocity of the form is investigated for the first time. A prescribed power-law surface temperature distribution of the form is considered. Mathematical model is constructed through the constitutive equations of second grade fluid.

Numerical Scheme for Solving Singular Two-Point Boundary Value Problems [PDF]
Journal of Applied Mathematics, 2013 Singular two-point boundary value problems (BVPs) are investigated using a new technique, namely, optimal homotopy asymptotic method (OHAM). OHAM provides a convenient way of controlling the convergence region and it does not need to identify an ...

Applications of OHAM and MOHAM for Fractional Seventh-Order SKI Equations
Journal of Applied Mathematics, 2021 In this article, a comparative study between optimal homotopy asymptotic method and multistage optimal homotopy asymptotic method is presented. These methods will be applied to obtain an approximate solution to the seventh-order Sawada-Kotera Ito equation.

Heat Transfer, Volume 52, Issue 4, Page 3389-3410, June 2023., 2023 Abstract This research presents a neural network algorithm to identify the best modeling and simulation methods and assumptions for the most widespread nanofluid combinations. The neural network algorithm is trained using data from earlier nanofluid experiments. A multilayer perceptron with one hidden layer was employed in the investigation. The neural
