Gallery aviation technology and traditions of aviation at the airport Medlánky in Brno
Kašpárek, Michal ; Marek, Jiří (referee) ; Šindlar, Jiljí (advisor)
The theme of Master thesis is a Gallery of aviation technology and traditions of aviation at the airport Gallery aviation technology and traditions of aviation at the airport Medlánky in Brno. The project insludes overall operation of the sports airport, then deal in detail operations of the museum and related services within the airport. The new campus will humbly entered in the countryside, in an attractive location Medláneckých hills creates another attractive feature and despite the complex operation and movement techniques does not create a barrier to the contrary territory it unites and is a natural center. Airports Medlanky was founded already in the twenties of the last century, and since then the area is relatively non-conceptually grew by more hangars and various outbuildings. Of these, only two were preserved original wooden sheds, which adds yet another new administrative and ceremonial buildings. Operational buildings set limits on technology, the new representative building it closes, and defining a space for people, nature trail connects the area, offers wonderful views and creates a public space that makes passers airport. The whole area is oriented to the back area and opens onto the landscape, wide area thus presents an iconic silhouette reperzentační building. The curve of the building provides space aircraft-makers to fly and allows collision-free movement of people and equipment around the airport and also generates a dignified space for aircraft to fly longer will. Exposure air museum at the second floor of the building and the visitor thus rises to individual gliders that levitate in space, the sun's rays make their reflections on the polished bonnets and backgrounds are vivid airports and skies. The museum offers a walk through the history of aviation in a different context than conventional hangars. The entire building is representative functionally and structurally divided into three parts. The ground floor closer to the a

Active Compensation of Tool Deflection
Zarboch, Jaromír ; Marek, Jiří (referee) ; Březina, Tomáš (advisor)
This paper deals with design of tool deflection compensation system for milling spindle C1, provided by company TOSHULIN, a.s. A simplified simulation model of the spindle supplemented by compensatory elements was built by using programs ANSYS, MD ADAMS, Matlab/Simulink. As action elements there were use three piezoactuators each controled by PID controler. Efficiency of this compensation system was verified based on performed simulations.

Horečky
Obrusníková, Magdalena ; Mašek, Radomír (referee) ; Marek, Jiří (advisor)
The main aim of the diploma thesis is the revitalization of the site Horečky in Beskydy mountains, which contains several abandoned buildings. In the introduction, the work provides an analysis in the wider context and comes up with a concept of urban strategy on the larger scale. The main item of the urban and architectural study itself is a complex of existing buildings called Pantata, Marianka and Panimama and their setting in the terraced hilly landscape. The first necessary step is purging the buildings of nonconceptual extensions, which were added in the past. The function, which was chosen based on the outcome of the analysis part is a recreational accommodation facility oriented on educational school trips and alternative forms of experience-based educational methods. The building Pantáta gets to be the main center of the function itself and the 3rd and 4th stock is designed as additional accommodation facility. The building is also complemented with an extension building located in the terrace in the sloping-down terrain. This spatial concept also enables expansion of the exterior space in front of the historical building. The building Marianka is designed to be the main accommodation facility. The building Panimama is removed and a forest-cabin accommodation area is designed at the plot as another alternative way of staying in nature. There are also other landscape interventions and pavilions designed within the thesis project.

Mobile turning machining center with vertical workpiece axis
Pomikálek, Adam ; Knoflíček, Radek (referee) ; Marek, Jiří (advisor)
The subject of this diploma thesis is the conceptual design of a mobile lathe centre with a vertical workpiece axis. First, a search in the field of mobile lathes, stationary lathes and methods of their transport is performed. Then, from the described transport machine options, the most suitable transport variant is selected, thanks to which variants of the mobile machine solution are created. Subsequently, the design of the winning variant is fully adapted to the method of transport using containers. Emphasis is placed on simple construction, maximum use of the transport packaging in the machine frame and easy assembly of the machine customer. For these reasons, the machine frame must consist of two containers. Finally, the assembly and adjustment of the machine tool are solved in combination with the verification of the functionality of the proposed concept.

Root cause analysis of scrap during production of bearing rings in a roller bearing company
Studýnka, Pavel ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
This diploma thesis concerns about measuring of rings of bearings from the input material, throughout machining processes, such as turning, heat treatment, grinding, till finishing operations as honing. Purpose of this thesis is to map all the processes in a roller/needle bearing company, measuring of rings of bearings, evaluating data, propose actions leading to decrease the number of scrap product and technical-economical evaluation of changed processes.
