**Foreword about Zdenek Dostal, Professor at VSB–Technical University of Ostrava, Faculty of Electrical Engineering and Computer Science, Department of Applied Mathematics:**

"Dear Readers, I am happy to have an opportunity to write a foreword to this edition of Advances in Electrical and Electronic Engineering with the papers of some of my colleagues from the Department of Applied Mathematics of Faculty of Electrical Engineering and Computer Science, VSB–Technical University of Ostrava and National Supercomputing Center. The collection includes the papers which illustrate the mathematical research of the above institutions. The papers are related not only to the fields of research which is well developed in both institutions, such as development of algorithms for the solution of the large problems arising in computational mechanics and electromagnetism, parallel algorithms, or new applications of boundary element method, but also to the fields that are new to both institutions, such as mathematical problems related to the modelling of electronic structures, problems described by stochastic partial differential equations, and inverse problems, local eigenvalue analysis with applications, or the analysis of dynamical systems. There are also papers on the application of recently developed methods to new problems, such as implementation of heterogeneous image registration by means of Total Finite Element Tearing and Interconnecting (TFETI) method or transient finite-boundary element simulation of electromagnetic forming of metal sheets, or papers on interesting mathematical problems motivated by the real world problems."
