New Refinements and Improvements of Some Trigonometric Inequalities Based on Padé Approximant
A multiple-point Padé approximant method is presented for approximating and bounding some trigonometric functions in this paper. We give new refinements and improvements of some trigonometric inequalities including Jordan’s inequality, Kober’s inequality,

One-log call iterative solution of the Colebrook equation for flow friction based on Pade polynomials [PDF]
The 80 year-old empirical Colebrook function zeta, widely used as an informal standard for hydraulic resistance, relates implicitly the unknown flow friction factor lambda, with the known Reynolds number Re and the known relative roughness of a pipe ...

Electromagnetic scattering beyond the weak regime: Solving the problem of divergent Born perturbation series by Padé approximants [PDF]
Electromagnetic scattering is the main phenomenon behind all optical measurement methods where one aims to retrieve the shape or physical properties of an unknown object by measuring how it scatters an incident optical field.

Multistep High-Order Methods for Nonlinear Equations Using Padé-Like Approximants
We present new high-order optimal iterative methods for solving a nonlinear equation, f(x)=0, by using Padé-like approximants. We compose optimal methods of order 4 with Newton’s step and substitute the derivative by using an appropriate rational ...

On the Study of Oscillating Viscous Flows by Using the Adomian-Padé Approximation
The Adomian-Padé technique is applied to examine two oscillating viscous flows, the Stokes’ second problem and the pressure-driven pulsating flow. Main purposes for studying oscillating flows are not only to verify the accuracy of the approximation ...
