Manufacturing of pin with flange
Procházka, Pavel ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The bachelor thesis is focused on the design of the towing hitch, which is used in the tractor. The component will be the production of a die forging technology made of low-alloy steel 13 242. The material is supplied as hot-rolled bars with a diameter of 60 mm and a length of 6 000 mm. The size of the production series has been set at 25,000 pieces per year. Due to the issue and the size of the forging, the component will be made on a power hammer. The machine Šmeral KHZ 8A, appears to be a suitable machine as the forging work was calculated at 89 kJ. The technical - economic evaluation takes into account material costs, which amount to 1,364,271 CZK. The die is made of tool steel 19 663, its purchase price is 73 000 CZK.

Performance Analysis of Programs Based on PIN Framework
Močáry, Peter ; Fiedor, Jan (referee) ; Pavela, Jiří (advisor)
Cieľom tejto práce je rozšíriť výkonnostný verzovací system - Perun implementáciou nového Tracer engine využívajúceho inštrumentačný nástroj PIN. Toto rozšírenie implementuje základné funkcie Tracer modulu a zároveň zber argumentov funkcií spolu so zberom dĺžky behu základných blokov programu. Tieto nové údaje spolu s vizualizáciami vytvorenými v tejto práci poskytujú potrebný kontext, ktorý zjednodušuje odhalenie zhoršenia výkonu. Okrem nástroja PIN využíva Tracer engine python knižnicu pyelftools na analýzu ladiacich informácií vo formáte DWARF pre zistenie podrobností o argumentoch funkcií pred procesom zberu údajov. Výsledný engine bol testovaný na viacerých implementáciách triediacich algoritmov a úspešne detekoval časovo najnáročnejšie funkcie spolu s informáciami o zvýšenej zložitosti súvisiacej s jej argumentom. Testovanie na projekte väčšieho rozsahu odhalilo, že v porovnaní s ostatnými implementáciami Tracer engine, tento nový engine pracuje lepšie alebo porovnateľne a produkuje správne výstupy.

Tail Units
Dula, Jan ; Mališ, Michal (referee) ; Urík, Tomáš (advisor)
In this bachelor´s thesis is created a survey of constructive solutions and lay-out of horizontal tail unit, solutions of horizontal stabilizer attachment and ways to control the elevator. In the introductory part the term which is used in this thesis are briefly explained. In the following part the possible configurations of the tail units are listed. From these configurations, some solutions are selected and they are closely classified. Any of these solutions provides a short description of the elevator control, the advantages and the disadvantages of this solution, an overview of selected horizontal stabilizer attachment and their detailed description.

Rolling Analysis of Turbocharger Pin Roller
Pazour, Martin ; Žatko, Miroslav (referee) ; Novotný, Pavel (advisor)
The subject of the diploma thesis is a description of movement of a roller which is a part of turbocharger. The diploma thesis is created in cooperation of the research department of Honeywell in Brno. The thesis consists of review concerning operating of turbochargers and possibilities of solving contact problems. Then static and dynamic conditions in contact are treated in the following part. Contact pressures are generated using numerical simulation in Ansys software. In the conclusion sizes and coefficients of friction which are recommended as the most suitable to achieve minimal wear of the components in contact.

Multipurpose hall in Holice
Rückerová, Eva ; Hron, Lukáš (referee) ; Šmak, Milan (advisor)
Master´s thesis deals with the design and assessment of the roof construction of the multi-purpose hall in Holice. The other two dimensions of the hall are 28 x 45 m. Height of the hall is 11,28 m. Roofing is done in three variants. The final solution is processed for one presentation. The main supporting element is formed by cross-linking arc beam made of laminated wood. Girders are spaced 5 m and connected purlins. Stability of the construction by three field bracings. The cladding is a rafter, shuttering of OSB particle that carry the roof deck.

Steel footbridge in Černotín
Kelar, Petr ; Štrba, Michal (referee) ; Barnat, Jan (advisor)
The thesis deal with structural design of steel footbridge for pedestrians and cyclist over the Bečva river in Černotín village. Span of the footbridge is 50 m. The basic material is steel S355 and S460. At the beginning were created two variants. First one is an arched footbridge and the second one is cable stayed footbridge. After evaluation variants was selected the cable stayed footbridge. The selected variant was assessed in detail including joints and bearings. Structure is designed in compliance with valid standards of ČSN EN and corresponds with ultimate and serviceability limit state. For structural design was used software RFEM 5.17.01 of Dlubal company.
