Abstract and Applied Analysis, 2012 We investigate squeezing flow between two large parallel plates by transforming the basic governing equations of the first grade fluid to an ordinary nonlinear differential equation using the stream functions ur(r,z,t)=(1/r)(∂ψ/∂z) and uz(r,z,t)=−(1/r ...

Nevşehir Bilim ve Teknoloji Dergisi, 2016 In this paper, we study the mixed Volterra-Fredholm integral equations of the second kind by means of optimal homotopy asymptotic method (OHAM) and Homotopy Perturbation method (HPM).Our approach is independent of time and contains simple computations with quite acceptable approximate solutions in which approximate solutions obtained by these methods ...

One‐Shot Method for Computing Generalized Winding Numbers
Computer Graphics Forum, Volume 44, Issue 5, August 2025.Abstract The generalized winding number is an essential part of the geometry processing toolkit, allowing to quantify how much a given point is inside a surface, even when the surface has boundaries and noise. We propose a new universal method to compute a generalized winding number, based only on the surface boundary and the intersections of a single ...

Engineering Reports, Volume 7, Issue 5, May 2025.Enhanced thermal performance of paraffin oil‐based Ti‐alloy nanofluids is investigated for 3D MHD Darcy‐Forchheimer flow over a bi‐directional stretching surface. Results reveal improved thermal conductivity and viscosity, with industrial applications in heat transfer systems, while magnetic fields reduce velocity and increase temperature due to ...

Dynamical Study of Fokker-Planck Equations by Using Optimal Homotopy Asymptotic Method
Mathematics, 2019 In this article, Optimal Homotopy Asymptotic Method (OHAM) is used to approximate results of time-fractional order Fokker-Planck equations. In this work, 3rd order results obtained through OHAM are compared with the exact solutions.

Analytical investigation of beam deformation equation using perturbation, homotopy perturbation, variational iteration and optimal homotopy asymptotic methods [PDF]
Carpathian Journal of Mathematics, 2011 The beam deformation equation has very wide applications in structural engineering. As a differential equation, it has its own problem concerning existence, uniqueness and methods of solutions. Often, original forms of governing differential equations used in engineering problems are simplified, and this process produces noise in the obtained answers ...

Asymptotic behavior of Moncrief Lines in constant curvature space‐times
Bulletin of the London Mathematical Society, Volume 57, Issue 5, Page 1347-1359, May 2025.Abstract We study the asymptotic behavior of Moncrief lines on 2+1$2+1$ maximal globally hyperbolic spatially compact space‐time M$M$ of nonnegative constant curvature. We show that when the unique geodesic lamination associated with M$M$ is either maximal uniquely ergodic or simplicial, the Moncrief line converges, as time goes to zero, to a unique ...
