Crane hook block - lifting capacity 25 tons
Šanca, Kristián ; Trčka, Tomáš (referee) ; Malášek, Jiří (advisor)
The crane block is the lower part of the hoist. It is designed to fulfill a load capacity of 25,000 kg, while being safe and as light as possible. The work describes the principle of the hoist. A design solution is chosen in which two ropes are wound on a drum. The calculation of the hoist is in the calculation part, the components of the hoist are further described and calculated, using basic strength calculations. Attached is a drawing of the assembly and important details.

Workplace for testing of the photodiodes
Šedo, Ondrej ; Poliak, Juraj (referee) ; Wilfert, Otakar (advisor)
This paper is focused on design of the workplace for measuring basic parameters and characteristics of standard photodiodes. There is also experimental test of its possibilities and comparison of the measurement results with the catalogue data. It also includes elaboration of an algorithm that processes the measurement data into visual presentation.

Coverage-Driven Testing for Multithreaded Programs
Lietavcová, Zuzana ; Šimková, Hana (referee) ; Letko, Zdeněk (advisor)
This work deals with a problem of searching errors in multithreaded programs using a coverage-driven testing technique as perceived in program Maple. The testing consists of two phases. In the first phase of testing a set of coverable behaviours of the tested program is being built. Consequently, the algorithm tries to achieve these behaviours with a help of deterministic test execution. The main acquisition of the work lays in a compact description of Maple including all the technical details. Based on the study of the tool there were weak places identified. Some of them are studied in detail, especially those which use random decision making and prioritizing of the forced behaviours. The result are several modifications of Maple, from which some lead to a higher number of exposed behaviours and higher error exposition in some cases. This is demonstrated on a test suite of parallel programs.

The Roofing of Terraces of a Stadium
Bartoň, Radek ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
My task was to propose and consider steel structure of roofing of a terraces on an athletic stadium. Terraces, with the ground-plan dimensions 12,0 x 80,0 m, are designed as a reinforced concrete structure and its structural analysis is not included in this thesis. Construction is situated in area of Rožnov pod Radhoštěm, which meant, It had to be accounted with considerable variable loads (wind, snow), which is associated with enlargement of a cross-sections. Cross sections of the main elements were proposed and considered and also selected joints and details of the structure. Assigned drawings are included in attachments of the thesis.

Manufacturing of a Pin
Glatter, Jiří ; Forejt, Milan (referee) ; Řiháček, Jan (advisor)
The work presents a proposal for the technology of production of a pin of gear assambly.The pin is used to position the wheel in a tapered roller bearing. Pin is made of 11 320.3 steel (11 320 5R), which is suitable for cold forming. Based on the study of cold forming and calculations, the methods of upsetting and extrusion were chosen. Most often, several methods are used for fabrication, which are mediated by a combined tool. It can also be made by any of the machining methods.

Determination of Dependencies for Evaluation of Stiffness Measurements of Rubber Bearings
Beseda, Vojtěch ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
The thesis deals with analysis of rigidity of rubber joint measurements. Characteristic, usage and behaviour of a rubber is described in the first part of the work. The following chapter describes problems and analyse production technology of the given component. The work continues by a preparation of several tests established based on information provided in the first chapter and from requirements of company. At the end, correlations and recommendations for appropriate measurement are concluded based on acquired data. The thesis is closed by a technological and economical evaluation which presents required cost for preparation, realization and analysis of tests.

Detail analysis of complex connection in the structure
Hokeš, Filip ; Hradil,, Petr (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to find and describe dependence between load carying capacity of a pin connection and a pin hole drilling. The dependence will be made in according to standard ČSN EN 1993-1-8, by theoretical solution and finally by finite element method in the ANSYS system. The second objective of the thesis is focused on a verification of load test results by numerical methods. Numerical solution will be made up in two analysis with different types of finite elements. The most fiiting model will be used as a basis for description of the relationship between capacity and diameter of drilling.

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.
