Fitted finite difference method for third order singularly perturbed convection diffusion equations with integral boundary condition

open access: yesArab Journal of Mathematical Sciences, 2019
A class of third order singularly perturbed convection diffusion type equations with integral boundary condition is considered. A numerical method based on a finite difference scheme on a Shishkin mesh is presented.

Stagnation‐point flow of the Walters′ B′ fluid with slip

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 61, Page 3249-3258, 2004., 2004
The steady two‐dimensional stagnation point flow of a non‐Newtonian Walters′ B′ fluid with slip is studied. The fluid impinges on the wall either orthogonally or obliquely. A finite difference technique is employed to obtain solutions.

Unsteady stagnation point flow of a non‐Newtonian second‐grade fluid

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 60, Page 3797-3807, 2003., 2003
The unsteady two‐dimensional flow of a viscoelastic second‐grade fluid impinging on an infinite plate is considered. The plate is making harmonic oscillations in its own plane. A finite difference technique is employed and solutions for small and large frequencies of the oscillations are obtained.

Distribution functions of Poisson random integrals: Analysis and computation [PDF]

open access: yes, 2010
We want to compute the cumulative distribution function of a one-dimensional Poisson stochastic integral $I(\krnl) = \displaystyle \int_0^T \krnl(s) N(ds)$, where $N$ is a Poisson random measure with control measure $n$ and $\krnl$ is a suitable kernel ...

Numerical Analysis of Transmission Lines Equation by new β-method Schemes

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
In this paper we develop a new β-method applied to the resolution of homogeneous transmission lines. A comparison with conventional methods used for this type of problems like FDTD method or classical β-method is also given.

Comment on `conservative discretizations of the Kepler motion'

open access: yes, 2009
We show that the exact integrator for the classical Kepler motion, recently found by Kozlov ({\it J. Phys. A: Math. Theor.\} {\bf 40} (2007) 4529-4539), can be derived in a simple natural way (using well known exact discretization of the harmonic ...

Variable-step finite difference schemes for the solution of Sturm-Liouville problems

open access: yes, 2014
We discuss the solution of regular and singular Sturm-Liouville problems by means of High Order Finite Difference Schemes. We describe a code to define a discrete problem and its numerical solution by means of linear algebra techniques.

Performance analysis of SSE and AVX instructions in multi-core CPUs and GPU computing on FDTD scheme for solid and fluid vibration problems [PDF]

open access: yes, 2014
In this work a unified treatment of solid and fluid vibration problems is developed by means of the Finite-Difference Time-Domain (FDTD). The scheme here proposed takes advantage from a scaling factor in the velocity fields that improves the performance ...

An adaptive stepsize algorithm for the numerical solving of initial-value problems

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
The present paper focuses on the efficient numerical solving of initial-value problems (IVPs) using digital computers and one-step numerical methods. We start from considering that the integration stepsize is the crucial factor in determining the number ...
