    • A penalization and regularization technique in shape optimization problems 

      Philip, P.; Tiba, D. (2013-12-31)
      We consider shape optimization problems, where the state is governed by elliptic partial differential equations. Using a regularization technique, unknown shapes are encoded via shape functions, turning the shape optimization ...
    • A direct algorithm in some free boundary problems 

      Murea, M.; Tiba, D. (2016-06-28)
      In this paper we propose a new algorithm for the well known elliptic obstacle problem and for parabolic variational inequalities like one and two phase Stefan problem and of obstacle type. Our approach enters the category ...
