An Analytic Shooting-Like Approach For The Solution of Nonlinear Boundary Value Problems
(Pergamon-Elsevier Science Ltd, 2011)
In this paper a novel approach is presented for an analytic approximate solution of nonlinear differential equations with boundary conditions. By converting the nonlinear problem into an initial value form, a shooting-like ...
An Optimal Variational Iteration Method
(Pergamon-Elsevier Science Ltd, 2011)
The variational iteration method is studied in the present work. The classical variational iteration method is improved and extended by introducing a new concept of a convergence accelerating parameter. A rigorous approach ...
Almost-Perfect Modules
(Cambridge Univ Press, 2010)
We call a module M almost perfect if every M-generated flat module is M-projective. Any perfect module is almost perfect. We characterize almost-perfect modules and investigate some of their properties. It is proved that ...
Exponential Attractors For Abstract Equations With Memory And Applications To Viscoelasticity
(Amer Inst Mathematical Sciences-Aims, 2015)
We consider an abstract equation with memory of the form partial derivative(t)x(t) + integral(infinity)(0) k(s)Ax(t-s)ds + Bx(t) = 0 where A, B are operators acting on some Banach space, and the convolution kernel k is a ...
Further Results On Fibre Products Of Kummer Covers And Curves With Many Points Over Finite Fields
(Amer Inst Mathematical Sciences-Aims, 2016)
We study fibre products of an arbitrary number of Kummer covers of the projective line over F-q under suitable weak assumptions. If q - 1 = r(n) for some prime r, then we completely determine the number of rational points ...
Global Attractor For The One Dimensional Wave Equation With Displacement Dependent Damping
(Pergamon-Elsevier Science Ltd, 2012)
We study the long-time behavior of solutions of the one dimensional wave equation with nonlinear damping coefficient. We prove that if the damping coefficient function is strictly positive near the origin then this equation ...
On Existence And Nonexistence Of The Positive Solutions Of Non-Newtonian Filtration Equation
(Amer Inst Mathematical Sciences, 2011)
The subject this investigation is existence and nonexistence of positive solutions of the following nonhomogeneous equation rho(vertical bar x vertical bar) partial derivative u/partial derivative t - Sigma(N)(i=1) ...
On Dual Baer Modules
(Cambridge Univ Press, 2010)
In this paper we introduce T-non-cosingular modules, dual Baer modules and K-modules. We prove that a module M is lifting and T-non-cosingular if and only if it is a dual Baer and K-module. Rings for which all modules are ...
Almost Unbiased Estimation Procedures Of Population Mean In Two-Occasion Successive Sampling
(Hacettepe Univ, Fac Sci, 2018)
The objective of this paper is to construct some unbiased estimators of the current population mean in two-occasion successive sampling. Utilizing the readily available information on an auxiliary variable on both occasions, ...
An Arma Type Fuzzy Time Series Forecasting Method Based On Particle Swarm Optimization
(Hindawi Ltd, 2013)
In the literature, fuzzy time series forecasting models generally include fuzzy lagged variables. Thus, these fuzzy time series models have only autoregressive structure. Using such fuzzy time series models can cause ...
