He-Laplace Method for Linear and Nonlinear Partial Differential Equations

Journal of Applied Mathematics, 2012
A new treatment for homotopy perturbation method is introduced. The new treatment is called He-Laplace method which is the coupling of the Laplace transform and the homotopy perturbation method using He’s polynomials.

Statistical Model of Shape Moments with Active Contour Evolution for Shape Detection and Segmentation [PDF]

, 2013
This paper describes a novel method for shape representation and robust image segmentation. The proposed method combines two well known methodologies, namely, statistical shape models and active contours implemented in level set framework.

Generic Newton points and the Newton poset in Iwahori double cosets [PDF]

, 2020
We consider the Newton stratification on Iwahori double cosets in the loop group of a reductive group. We describe a group-theoretic condition on the generic Newton point, called cordiality, under which the Newton poset (i.e.

An Accelerated Homotopy Perturbation Method for Solving Nonlinear Two-Dimensional Volterra-Fredholm Integrodifferential Equations

Advances in Mathematical Physics, 2017
We propose and apply coupling of the variational iteration method (VIM) and homotopy perturbation method (HPM) to solve nonlinear mixed Volterra-Fredholm integrodifferential equations (VFIDE).

Variational Iteration Method for Initial and Boundary Value Problems Using He's Polynomials

International Journal of Differential Equations, 2010
This paper outlines a detailed study of the coupling of He's polynomials with correction functional of variational iteration method (VIM) for solving various initial and boundary value problems. The elegant coupling gives rise to the modified versions of
