Thickness of sheet and hardness of welded joins
Valášek, Daniel ; IAE, Michal Loskot, IWE, (referee) ; Molliková, Eva (advisor)
Theme of this bachelor’s thesis is to determine the effect of material thickness, laser beam power and the material itself on hardness of the weld joint created by laser welding of construction steels. In addition to description of welding technology, this thesis also includes description of the undertaken experiment and its results which include photographs of microstructure from all weld joint zones and photograph evaluation.

Coating properties of cutting tools carbide
Doležalová, Petra ; Bumbálek, Bohumil (referee) ; Osička, Karel (advisor)
Diploma thesis is divided into two parts. The first part is focused on theoretical description of coating methods, on currently used coatings, their properties and it is also focused on description of methods, which are used for analyzing each property. The second part focuses on testing of coatings and analyzing of the values obtained from experiments. The aim of this thesis is then to compare the properties of the tested coatings.

Thin-film systems
Kuchařík, Jan ; Máca, Josef (referee) ; Zatloukal, Miroslav (advisor)
This bachelor thesis concerns to create of thin films on various types of substrates. In the theoretical parts is an overview of the formation of thin films using several techniques. The thesis contains an overview of substrate cleaning processes before the deposition of layer plates and tools for evaluating their properties. Finally, the masking method is discussed. In the experimental part, the acquaintance with the NP - 12 sputtering device and the production of samples took place. The adhesion of the produced samples was evaluated. Electrolysis of samples with titanium coated followed. Finally, the silicon substrate was masked.

Perception of beauty - biological vs. cultural determinants
Obdržálková, Zita ; Soukup, Václav (advisor) ; Soukup, Martin (referee)
This thesis deals with problems of biological and cultural determinants influencing perception of beauty. It attempts to find out if there is a common biological basis of perception of beauty or if beauty represents merely a sociocultural construct - product of a specific culture. With respect to biological determinants it concerns biological processes significantly influencing perception of beauty. In this context, these processes include probably innate evolutionary adaptations, effects of brain cognitive systems and neural correlates processing perceptions of beautiful objects. In connection with cultural determinants it presents studies emphasizing cross-cultural differences in perception of beauty. Further subject of the thesis is an aesthetic conception of subjective and objective beauty and related concept of beauty based on mathematical relations. In this connection, the creation of universally beautiful objects based on fixed mathematical rules as well as the possibility of exact measurement of beauty are discussed.
