## Orbital period modulation of the eclipsing binary system ER Vulpeculae: Real or not?

AbstractThe reanalysis of the timing data of the binary system ER Vulpeculae revealed the superposition of a relatively slow increasing…

## Application of the Jacobi-Davidson method to accurate analysis of singular linear hydrodynamic stability problems

AbstractThe aim of this paper is to show that the Jacobi–Davidson (JD) method is an accurate and robust method for…

## Laguerre collocation solutions to boundary layer type problems

AbstractIn this paper a Laguerre collocation type method based on usual Laguerre functions is designed in order to solve high…

## A mixed finite element discretization scheme for a concrete carbonation model with concentration-dependent porosity

AbstractWe investigate a prototypical reaction–diffusion-flow problem in saturated/unsaturated porous media. The special features of our problem are twofold: the reaction produces…

## A coupled finite element–global random walk approach to advection-dominated transport in porous media with random hydraulic conductivity

AbstractSolute transport through heterogeneous porous media considered in environmental and industrial problems is often characterized by high Péclet numbers. In…

## Numerical demodulation of a Gaussian white noise modulated in amplitude by a deterministic volatility

AbstractThe Gaussian white noise modulated in amplitude is defined as the product of a Gaussian white noise and a slowly…

## On an Aitken-Newton type method

Abstract We study the solving of nonlinear equations by an iterative method of Aitken type, which has the interpolation nodes…

## On a Newton-Steffensen type method

Abstract In this paper we study the convergence of a Newton-Steffensen type method for solving nonlinear equations in R, introduced by…
