The method of successive approximation is considered for solving the contact elasticity problem which corresponds to the quasivariational Signorini problem. Auxiliary problems with given frictions arising from each external step of this method are solved by the Uzawa method with iterative proximal regularization of the modified Lagrangian functional. Stabilization of the sequence of auxiliary f...

The transfer function of IIR all-pass filters is a rational function of ω. However, the optimization of such a rational function using the successive projections method, which has a wider range of application than the Remez algorithm, has not been presented. In this paper, we propose designing IIR allpass filters using the successive projections method. key words: successive projections method,...
