Solution of initial and boundary value problems by the variational iteration method
Altintan, D.; Uğur, Ömür (2014-03-15)
The Variational Iteration Method (VIM) is an iterative method that obtains the approximate solution of differential equations. In this paper, it is proven that whenever the initial approximation satisfies the initial conditions, vim obtains the solution of Initial Value Problems (IVPs) with a single iteration. By using this fact, we propose a new algorithm for Boundary Value Problems (BVPs): linear and nonlinear ones. Main advantage of the present method is that it does not use Green's function, however, it...

Dynamics of elderly-caregiving among different socioeconomic groups in Ankara, Turkey
Sel, Gizem Irmak; Beşpınar Akgüner, Fatma Umut; Department of Gender and Women's Studies (2017)
In the last 20 years, the number of older adults aged 60 and over has been increasing in Turkey in accordance with the increased life expectancy. Accordingly, the needs of ageing population are also changing. However, ageing studies in Turkey do not focus on how these new dynamics are experienced by families. This thesis focuses on how elderly-caregiving is experienced among different socio-economic groups and the effects of this responsibility on their family relations. The study defines caring labour as c...
Application of a Robust Multigrid Technique for the Parallel Solution of Initial-Boundary Value Problems
Martynenko, S.I.; Gökalp, İskender; Bakhtin, V.A.; Karaca, Mehmet; Toktaliev, P.D.; Semenev, P.A. (2022-12-01)
This article is devoted to the construction of a parallel multigrid algorithm for the numerical solution of (non)linear initial-boundary value problems (implicit schemes) based on a robust multigrid technique (RMT). A distinctive feature of the proposed algorithm is the possibility of the parallel solution of initial-boundary value problems and initial-boundary value problems in a unified manner involving 3m independent computers (threads, if the OpenMP parallelization technology is used), m = 1, 2, 3, …. C...
Investigation of periodic boundary conditions in multi-passage cascade flows using overset grids
Tuncer, İsmail Hakkı; Sanz, Wolfgang (1998-01-01)
Copyright © 1998 by ASME.A Navier-Stokes solution method with overset grids is applied to unsteady multi-passage cascade flows, and the unsteady blade loadings are compared against the single passage solutions with the direct store interblade boundary condition. In the overset grid solutions, the multipassage domain is discretized with O-type grids around each blade and a rectangular background grid. Blade grids are allowed to move in time relative to the background grid as prescribed by the oscillatory plu...
