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.

Triumph of Ugliness
Kolářová, Monika ; Zálešák, Jan (referee) ; Houser, Milan (advisor)
Bachelor theses is my engagement with phenomenon of body, focused on the theme of beauty and ugliness. Through the Dionysian body type I am trying to capture the weight of physical imperfections. In contrast with the delicacy and subtlety glaze paintings I am trying to achieve a balance between the representatives of the general phenomenon of beauty and ugliness.

Postavení a výchova třešně ptačí v porostu ve stavu převodu na les střední (ŠLP Křtiny - polesí Vranov)
Žalek, Mikuláš
Wild cherry is a promising tree for our forest management for ecological and economical reasons. In order to achieve a higher economic valuation of cherry wood, a special silvicultural measure must be carried out - artificial pruning. The pruning means removing the lower large branches and thus obtaining long, more quality boles without knots. The pruning of cherries took place in two differently old stands at the Training Forest Enterprise Křtiny. In stand A young wild cherry trees were pruned in three different ways: leaving only this year's increment (S), leaving the last whorl (P) and control, i.e. no pruning (K). In stand B several target trees, that were pruned, were selected and several control cherries without pruning for comparison of increments. The results show that pruning does not influence height growth, but the diameter growth has decreased with increasing intensity of pruning. The same decrease is observed for basal area increment. The data suggest that pruning should be done moderately at a younger stage of cherry development, when the removed branches are not too large.

Obesity and fat shaming in media on the example Patricie Solaříková and Super.cz
Bečvářová, Lucie ; Krobová, Tereza (advisor) ; Osvaldová, Barbora (referee)
The adoration of thinness and the cult of perfect body has been an issue for many decades; with substantial contributions of the mass media and the press. As consequence, the phenomena of fat-shaming and fat-glorification become prominent, either by denouncing obesity and humiliating the overweight, or by worshipping the obese and elevating their status above the slender people. The theoretical part of the thesis aims to introduce the first phenomenon, which condemns the corpulent population disregarding their state of health and other aspects of life, capable of causing an unfounded weight increase, and to depict the approach of the media (tabloids in particular) towards the excess weight. The practical part of the thesis is concerned with analysing selected articles of a tabloid journal Super.cz, beginning with characterising its content, target audience and focus, and strives to reveal specific instances of fat-shaming on articles regarding the fluctuating weight of actress Patricie Solaříková between years 2013 and 2017. The practical part opens with presentation of the actress and apart from analysing the approach of Super.cz in articles regarding the actress' weight, the thesis deals with the frequency of such articles and the proportion of the aforementioned articles to columns concerned...

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.
