Signorini problem with a solution dependent coefficient of friction (model with given friction): Approximation and numerical realization [PDF]

open access: yes, 2001
summary:Contact problems with given friction and the coefficient of friction depending on their solutions are studied. We prove the existence of at least one solution; uniqueness is obtained under additional assumptions on the coefficient of friction ...

Interior Point Methods for Massive Support Vector Machines

open access: yes, 2000
We investigate the use of interior point methods for solving quadratic programming problems with a small number of linear constraints where the quadratic term consists of a low-rank update to a positive semi-de nite matrix. Several formulations of the
