in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
We prove the classical result regarding the solvability of the Dirichlet problem for bounded domains with sufficiently smooth boundaries. We present the method described in [7], the main ingredient being the Fredhom alternative applied to a suitably constructed compact operator.
A nonlinear Dirichlet boundary value problem is approximated by an orthogonal spline collocation scheme using piecewise Hermite bicubic functions. Existence, local uniqueness, and error analysis of the collocation solution and convergence of Newton’s method are studied. The mesh independence principle for the collocation problem is proved and used to develop an efficient multilevel solution met...
Introduction: Problem solving skill in one of the necessities of the people’s educational, occupational and social life. From the one hand, pre-elementary school age is the most important period for teaching and learning and acquiring necessary skills such as problem solving skill. According to it, the objective of the present study was to investigate teaching successful intelligence on pre-ele...
Rumination and issue resolution methods are among the important and effective factors on people mental health. This study aims to explain the role of moderator in problem-solving strategies between rumination and depression was conducted. The sample consisted of 200 female undergraduate students Azad University Qom that was asked of them to complete the Beck Depression scale Inventory (BDI-II),...
The operator of double differentiation, perturbed by the composition differentiation and a convolution one, on finite interval with Dirichlet boundary conditions is considered. We obtain uniform stability recovering kernel from spectrum in weighted $L_2$-norm norm. For this purpose, we successively prove each step algorithm for solving inverse problem both norms. Besides justifying numerical co...
A quasi-conformal mapping of the parametric domain onto the underlying physical domain is used to generate a 2D structured mesh with required properties: grid line orthogonality and prescribed mesh point clustering near the domain boundary. The functions implementing the mapping are sought by solving the Dirichlet problem for the elliptic partial differential equations. An additional control fo...
We study the convergence of the finite element method with Lagrange multipliers for approximately solving the Dirichlet problem for a second-order elliptic equation in a plane domain with piecewise smooth boundary. Assuming mesh refinements around the corners, we construct families of boundary subspaces that are compatible with triangular Lagrange elements in the interior, and we carry out the ...
