AbstractWe consider a mathematical model which describes the quasistatic contact between a viscoelastic body and a deformable obstacle, the so-called…
A mixed variational formulation of a contact problem with wear
AbstractWe consider a mathematical model which describes the sliding frictional contact between a viscoplastic body and an obstacle, the so-called…
Detection of low level periodic signals through enhanced self-correlation method. The case of ER Vulpeculae
AbstractThe self-correlation (SC) method proposed three decades ago by Percy, Jakate and Matthews is a complementary time series analysis method…
On the accuracy of pseudospectral differentiation
AbstractFor various grids on a finite interval we measure the accurarcy of pseudospectral (collocation) differentiation matrices using two parameters. The…
