Safety and fluency increasing - road I/43 Černá Hora - Sebranice
Bažant, Petr ; Tesař, Jiří (referee) ; Všetečka, Martin (advisor)
A part of the road I/43 in the section between Černá Hora and Sebranice is the subject of diploma thesis. The output of thesis is to identify problematic parts of the safety and fluency of traffic and to propose appropriate measures. The road I/43 is very problematic and discussed of these aspects. Becouse of the character and the results of traffic accidents is called Highway of death. The thesis contains proposals of structural modification in selected problematic sections. These structural modifications are intended to increase the safety of traffic, but in order to limit of flow of traffic. Depending on the long-delayed contruction of expressway R43 is in order to make quick and effective increase the safety and the fluency of traffic counting with traffic intensity in the full range.

Application of modern methods for production of mobile phone storage stand
Tesař, Jaroslav ; Nejedlý, Jindřich (referee) ; Sedlák, Josef (advisor)
The thesis was made as a bachelor’s project on Faculty of Mechanical Engineering, Brno University of Technology. In the theoretical part methods of Reverse Engineering were described. The principle of the following technology, the Rapid Prototyping, was also explained and the summary of advantages and disadvantages and use in technical practice for the most important methods was made. In the experimental part of the thesis the modern methods were applied for manufacturing a cell phone holder. By this the possibility of these technologies to work with complexly shaped models was verified. The casting to a silicon form was used as the alternative method of manufacturing. The summary of possibilities of manufacturing with these technologies and technical and economical evaluation were made in the end of the thesis.

Methods for the determination of radiological impact of the food chains
Tesař, Jakub ; Bartusková,, Miluše (referee) ; Havránková, Barbora (advisor)
The diploma work presents comprehensive overview of methods of determination of radiological impact on food chains. It describes the determination of radionuclides in groceries in common radiation situation and in unusual radiation situation. Practical part of the work presents two model radiation events. These are radiation event in the territory of Czech Republic and radiation event in the territory of other country and its impact on Czech Republic. In the end both model situations are compared.

Secondary materials from household waste and their position in the global market
Tesař, Jan ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
The barchelor thesis is focused on the issues of material recovery of municipal waste. The work presents the basic concepts of waste management and resource data to help analyze the current virtual situation in the field of waste management. Work specifies the components with the greatest potential for material recovery. For the selected folder, which can be commonly referred to secondary raw materials, work tries to describe the flow of materials and meet with their potential application in the market.

Fabrication and characterization of atomically thin layers
Tesař, Jan ; Kunc, Jan (referee) ; Procházka, Pavel (advisor)
Tato práce se zabývá oblastí dvourozměrných materiálů, jejich přípravou a analýzou. Pravděpodobně nejznámějším zástupcem dvourozměrných materiálů je grafen. Tento 2D allotrop uhlíku, někdy nazývaný „otec 2D materiálů“, v sobě spojuje neobyčejnou kombinaci elektrických, tepelných a mechanických vlastností. Grafen získal mnoho pozornosti a byl také připraven mnoha metodami. Jedna z těchto metod však stále vyniká nad ostatními kvalitou produkovaného grafenu. Mechanická exfoliace je ve srovnání s jinými technikami velmi jednoduchá, takto připravený grafen je však nejkvalitnější. Práce je také zaměřena na optimalizaci procesu tvorby heterostruktur složených z vrstev grafenu a hBN. Dle prezentovaného postupu bylo připraveno několik van der Waalsových heterostruktur, které byly analyzovány Ramanovskou spektroskopií, mikroskopií atomových sil a nízkoenergiovou elektronovou mikroskopií. Měření pohyblivosti nosičů náboje bylo provedeno v GFET uspořádání. Získané hodnoty pohyblivosti prokázaly vynikající transportní vlastnosti exfoliovaného grafenu v porovnání s grafenem připraveným jinými metodami. V práci popsaný proces přípravy je tedy vhodný pro výrobu kvalitních heterostruktur.
