Modern finishing methods of implant processing
Večeřa, Tomáš ; Ohnišťová, Petra (referee) ; Píška, Miroslav (advisor)
This paper provides a general overview of joint implants and an overview of used contemporary materials and methods of fabrication of implants, including additive methods. More attention is paid to finishing methods of drag finishing and a new method of dry electropolishing used in DLyte system. In the experimental part, an experiment for analyzing and comparing the effect of DLyte system on a sample surface is proposed. Six samples of titanium alloy Ti6Al4V with different initial roughness are prepared. Their initial surface structure is studied.

Optimization in Financial Applications
Večeřa, Tomáš ; Cabalka, Matouš (referee) ; Popela, Pavel (advisor)
The main purpose of this thesis is to create an efficient stock portfolio, specifically to optimize current distribution of stock index S&P 500. The building process consist of well-established mathematical-economical methods, which are then improved by applying mathematical models from statistics and optimization. Firstly, we define essential terms in order to reach deeper understanding of used methods. Afterwards, process of thorough selection of stocks and sectors comes to place. Data are then processed in program GAMS in three different ways, depending on investors preference. Although this approach was applied to current era, its principles are applicable to any given timeline.

Návrh naučné stezky v území obce Ostrov u Macochy
Večeřa, Tomáš
This diploma thesis addresses recreation, relaxation and spending of free time in CHKO Moravsky kras, particularly in the Ostrov u Macochy community. In the area of the community there are many natural attractions, significant architectural objects and interesting tourist attractions. On the basis of field surveys of the territory and sociological surveys a 8,3 km long nature trail was designed on which 11 information boards are situated. The method of marking the trail, layout of the individual information panels, supporting infrastructure and possible sources of funding is addressed in the thesis. The nature trail was designed in compliance with the interest of the community, nature conservation bodies but also the users. All the materials and proposals can be used as the basis for implementation of the nature trail or structure serving for recreation in the community.
