Souček, Prokop ; SMUTNÝ, Vladimír (advisor) ; BERNARD, Jan (referee)
In this diploma thesis I summarize and analyze information about cinematographers of the 70`s and 80`s of the 20th century. I deal with the basics of theory in the context of the period, as well as artistic relationships, and detailed analysis of specific films, with the target to explain the innovative visual procedures established in this period in Russia. I aim to show the influence of the unique production of the period on todays work by analyzing given means of expression.

The aim of the present work was to study the mechanical properties of thin amorphous MoBC coatings and MoBC coatings consisting of nanocrystalline Mo2BC embedded in amorphous MoBC matrix. The hardness of the amorphous MoBC coatings (20 GPa) is comparable with the common amorphous diamond-like carbon coatings, however their elastic modulus as well as fracture toughness and ductility are significantly higher. Magnetron sputtering of three targets, B4C, C and Mo, for MoBC was used for coatings preparation. The aim of this work was to study the mechanical and tribological properties of MoBC coatings deposited on high speed steel substrate. The classification of MoBC coatings was performed using an impact tester in a dynamic mode and enabled us to predict the limit load causing the coating destruction.
