Machining technology of external threads
Kabrda, Martin ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
This bachelor's thesis focused on "Thread cutting technology" complexly deals with the individual types of threads, their designation and their use in practice, including norms specifying their standardization. There are also described methods of machining of external threads, which include cutting, turning, milling or grinding. The last chapter describes methods of economic comparison of individual machining methods.

Tools for threading and their use
Veselý, Václav ; Polzer, Aleš (referee) ; Sliwková, Petra (advisor)
The bachelor’s thesis Tools for threading and their use deals with issues connected to tools, the materials used and their usage in the field of mechanical engineering. Individual parts of the thesis cover types of tools for threading, methods of threading and materials suitable for tap making. Further, the range of monolithic milling taps in the producers’ supply is also analysed.

Fingerprints Generator
Chaloupka, Radek ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
Algorithms for fingerprints recognition are already known for long time and there is also an effort for their best optimization. This master's thesis is dealing with an opposite approach, where the fingerprints are not being recognized, but are generated on the minutiae position basis. Such algorithm is then free of the minutiae detection from image and enhancements of fingerprints. Results of this work are the synthetic images generated according to few given parameters, especially minutiae.

Fingerprint biometry
Smékal, Ondřej ; Drahanský, Martin (referee) ; Fedra, Petr (advisor)
Algorithms designed for identification and verification persons by fingerprints recognition are spread and used as in forensics aplications as in private sector for a long time. The aim of this thesis is to make us aquainted with various aplicated mathematic models of fingerprint processing in digital way. Second task is the presentation algorithmic solution of chosen subject identification procedure by force of Fingerprint matching. Algorithm is solid in the development environment platform Matlab.

Alternative designs for connection with cover and housing oil module
Svoboda, Vít ; František, Ondřej (referee) ; Škopán, Miroslav (advisor)
This diploma thesis describes the design of new connections and modification of existing connections cover and housing of oil module for trucks. This connection must resist the effects of operating oil trucks modules. These effects include pressure pulsation, temperature fluctuations, vibrations and weather conditions. The most important is the resistance of cover to rotation and loss of tightness. The work includes research of different connections usable for this application. Other research focuses on the use of connection of other manufacturers in the market. The work included a proposal of possible solutions for the modification of cover and housing and their evaluation using specified criteria with rating matrix. The final part deals with the development of the three best evaluated proposed solution. For each solution is made as necessary calculations, drawings and next steps of implementation of individual solutions.

Production of sleeper screw
Bartošek, Filip ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
Bachelor thesis developed in the bachelor degrees addresses technological process of the production sleeper screw. The production uses technology volume thermoforming. The project was elaborated in cooperation with the company ŠROUBÁRNA KYJOV s.r.o. The screw will be made from material ČSN 11 503. This material is unalloyed construction steel with property of weld. Based on the literature study technology volume thermoforming was chosen tamping in closed instrument for the production of head screw. For the production of screw-thread was chosen technology of rolling. For the production head of screw was chosen horizontal fitting press machine. After the production there were used surfacing by galvanic zinc coating because of the better corrosion resistance.

Production of screw-thread in small engineering company.
Straka, Jiří ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This work, wrought in branch of engineering technology in terms of baccalaureate studies, mentions the basic type partitioning of screw threads and their screw-threads labelling. There are presented some possibilities of screw threads manufacturing by chip-forming operation and by chipless machining operation, both with using of appropriate tools. Further the methods of production used in small machine-works are described. In this case the small machine-works is represented by secondary technical school.

Machining threading holes with cutting operation, pressing and shaping.
Rybář, Pavel ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This project wrought in terms of bachelor studies program 2307 submits a proposal of technology of production internal thread in thin-walled components. Selection of technology is done on the basis of three basic methods evaluation – welding nuts, riveting nuts and thermal shaping. On the basis of literary studies the optimal application is proposed. There is reduced choice of tools and assembly equipment used only for one type of technology. The choice of fastening parts material is possible done in conformity with product material, thread strength according to whole construction or design engineer choice. For proper choice of technology there are technical data sheets of fastening parts and description of thread mechanical properties.

Connection accessories - past and present
LANG, Aleš
The theoretical part of the thesis focuses on the history and present selected fasteners. For the period of the first elements of fasteners, the development of mass production and standardization process follows the thread until today. In the practical part are present selected individual types of fasteners, their properties and uses. Individual elements of fasteners are classified according to the manner of their use.
