## Automatic Trend Estimation

Book summaryOriginal automatic algorithms for processing nonstationary time series containing a stationary noise superposed over a nonmonotonic trend are presented.…

## A history-dependent contact problem with unilateral constraint

AbstractWe consider a mathematical model which describes the quasistatic contact between a viscoplastic body and a foundation. The contact is…

## A class of numerical methods for autonomous initial value problems

AbstractIn this paper we introduce a class of explicit numerical methods for approximating the solutions of scalar initial value problems…

## A numerical method for the solution of an autonomous initial value problem

AbstractUsing a known interpolation formula we introduce a class of numerical methods for approximating the solutions of scalar initial value…

## An elastic contact problem with normal compliance and memory term

AbstractWe consider a history-dependent problem which describes the contact between an elastic body and an obstacle, the so-called foundation. The…

## Global random walk algorithm for diffusion processes

AbstractThe Global Random Walk algorithm (GRW) performs the simultaneous tracking on a fixed grid of large collections of particles, while…

## Biperiodic orbital period modulation of the W UMa binary system CK Bootis

AbstractA study of the orbital period variation of the W UMa system CK Bootis is made using an extended observational…

## Spectral collocation solutions to multiparameter Mathieu’s system

AbstractOur main aim is the accurate computation of a large number of specified eigenvalues and eigenvectors of Mathieu’s system as…
