Design of chain tool magazine
Mucha, Roman ; Bradáč, František (referee) ; Pavlík, Jan (advisor)
The aim of the Master´s thesis is to design a chain tool magazine for a heavy duty machining centre for the non-rotational parts production. The Master’s thesis is ordered by TOS KURIM - OS, a.s. Company. The first part contains the analysis of the solved problems with the overview on the automatic tool changers, and the next part of the thesis deals with the proposal of options. Design of the chosen solution of the chain tool magazine is made in the next step, including sizing of the main parts. The 3D model of the chain tool magazine and drawings are included.

Problematic of Fast Automatic Tool Change by Working Machinery
Pavlík, Jan ; Marek, Jiří (referee) ; Velíšek,, Karol (referee) ; Demeč, Peter (referee) ; Kolíbal, Zdeněk (advisor)
This dissertation thesis is focused on the problem of the Automatic Tool Change for milling centers, which is recently shown as a very current topic. The content of this work is to conduct a comprehensive research of various types of ATC depending on the type of machine, as well as research of the current tool interface relating closely with these problems. There was made a comprehensive analysis on the basis of data obtained by comprehensive research, from which both the main factors affecting this topic and the area dealed and developed by this work resulted. The most problematic area of machinery used nowdays for the Atomatic Tool Change was detected as manipulator provided the exchange between spindle and tool storage. Kinematic structure and design of individual elements affects very significantly the dynamics of the whole process of exchange of tools. Therefore, the work is focused on problematic of the manipulator. The main results of this thesis are constructional design of several types of manipulators, which were partly realized within the project 1.2.4 of Brno department of RCMT in the form of the testing stands. There was developed simulation models for selected types of manipulators which were verificated by measuring on the real stand. On the basis of abovementioned problem there was identified another key issue related not only to the exchange process but also with complex problem of service life of spindle. It is a grab force in the process of picking tools. The work outlines the possibilities for further research of these forces on the service file of spindle (especially on service life of bering groups of spindle).

Air navigation in area of Africa
Míček, Petr ; Imriš, Pavel (referee) ; Raudenský, Miroslav (advisor)
The aim of this bachelor's thesis is to prepare navigation flight over uninhabited areas of Africa. The thesis is divided into three main chapters. First part deals with navigation coverage of inland parts of Africa. The second part is dedicated to preflight preparations and flight performance in uninhabited areas, using comparative navigation and computational navigation. Flight from Paris to Cape Town is suggested in the third part.

Call Sign Detection and Recognition in VHF Communication
Dedič, Juraj ; Kocour, Martin (referee) ; Szőke, Igor (advisor)
This work explores the processing of data from air traffic communication in order to detect and recognize the~call signs it contains. Particularly it involves recognizing these call signs in human made and automated text transcripts of the communication between pilots and air traffic controllers. The thesis compares various ways of solving this and describes their problems. It implements a system for the identification of these call signs using a suitable technology based on large language models. One of the outputs of this work is a service that is able to distinguish the call signs, which enables indexation and sorting of this data in an efficient way.
