In the tenth issue of the journal along with regular scientific articles we publish two works prepared not only by leading scientists presenting their new developments, but also by distinguished university teachers. In these works our colleagues turn to the generalization of scientific achievements in two relevant areas of applied research. As one of the authors, prof. M. V. Zhukovsky says: “The level of scientific knowledge and technical capabilities in a variety of areas is growing so quickly that approximately once every twenty to thirty years a cardinal, sometimes almost revolutionary change occurs in one or another technical area.” Our authors have undertaken to summarize the most important scientific achievements in their field and bring them to a form that will be used in the educational process.
