An Approximate Analytical Solution for the Stepped Bearing
Journal of Applied Mechanics, 1961Previously, solutions of the problem of the Rayleigh-type bearing with a step which is not straight have involved the use of the electrolytic tank or the use of relaxation methods, both of which are somewhat inconvenient as compared with the approximate analytical method described in this paper.

Approximate analytical solution of nucleation problems
Materials Science and Engineering: A, 1993Abstract A Fokker-Planck-like equation describing the homogeneous nucleation process in one-component system is solved analytically by a novel method based on boundary layer theory combined with a Green function technique. Important characteristics of nucleation (nucleation rate, integrated flux, time lag) are determined. The accuracy of the approach

Approximate analytic solutions to the Skyrme equation
Journal of Mathematical Physics, 1992The asymptotic properties and the stability of the solutions of the Skyrme nonlinear differential equation for the profile function F are discussed. Using rational approximants for σ=cos F some different ways of finding approximate analytic solutions to the equation are discussed.

Analytical approximations to the solution of the Blasius equation
Acta Mechanica, 1981Direct integration of the classical Blasius equation yields a weighted integral condition for the flow. The accuracy of the solution is improved dramatically when the series is rewritten to avoid the region of divergence. The first term of this new series approximates the stress accurately to 0(10{-4}).

Approximate analytic solutions for nonsimilar boundary layers.
AIAA Journal, 1967The Crocco equation for zero pressure gradient and a constant viscosity density product is linearized and the results applied to boundary-layer problems where the given initial profile is much different from the Blasius profile. Four linearization assumptions are used, each of which leads to an eigenvalue problem having a discrete spectrum of ...

Analytical Approximate Solutions for Vasicek Equation
SSRN Electronic Journal, 2007This paper presents a theoretical analysis for the Vasicek equation in finance. The Adomian decomposition approach is introduced and the analytical solution is obtained. The results reported in this work provide further evidence of the importance of Adomian decomposition in finding the solution of partial differential equation.

Approximate analytic solution of a quasipotential equation
Theoretical and Mathematical Physics, 1988A method is proposed for constructing a solution of a relativistic Logunov-Tavkhelidze quasipotential equation in the form of an expansion with respect to eigenfunctions of the nonrelativistic problem. The method is designed for the use of a computer in a system of analytic calculations.

Approximate Analytical Solutions for Overland Flows
Water Resources Research, 1990Following the study of Govindaraju et al. (1988), approximate analytical solutions are presented to the diffusion and kinematic wave models subject to space and time‐varying rainfall. An approximation in the form of the first term of an infinite sine series has been considered. This converts the partial differential equation to an ordinary differential
