Mini dumper for transporting bulk material
Sedláček, Tomáš ; Škopán, Miroslav (referee) ; Zeizinger, Lukáš (advisor)
The bachelor's thesis deals with the conceptual design of a minidumper. These machines are primarily used for transporting bulk material in small-scale earthworks. The introductory research describes selected similar devices. The research section serves as a basis for selecting a suitable conceptual solution. In the thesis, the solution of a tracked minidumper with a hydrostatic drive system and a hydraulic tipping of the dump body is selected. Part of the conceptual solution design is the design of the hydraulic circuit. Furthermore, the construction of the tracked chassis and other selected components is specified. The calculation section focuses on machine's drive system and the tipping of the dump body. This section covers the selection of the power unit, hydraulic pump, hydraulic motors and the linear hydraulic actuator. The end of the thesis is dedicated to the strength analysis of the machine's frame. The frame is subjected to strength analyses using the finite element method. Throughout the strength analyses, the frame is modified to enhance its load-bearing capacity. Drawing documentation for the final version of the frame is created. The thesis also includes drawing documentation of the minidumper assembly.

Robotized workplace for treatment of thermoplastic parts
Sedláček, Tomáš ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
The goal of this diploma thesis is to design a robotized workplace for treatment of thermoplastic products based on documentation from a real project announced by Form s. r. o. In order to understand a problematic of robots and robotized workplaces, the theoretic introduction in the beginning of work is reserved for. Besides a brief summary of robot history the introduction brings also some overview on present robot applications and it tries to classify robots into various groups according different standpoints. The main part of the theory however deals with optimized design of robotized workplaces by using a systematic approach. The topic covers also a robot safety. There are mentioned sources of safety risks and ways how to avoid them. The presented theory is at last used in the following, most crucial, part of the thesis – the final design itself. An attention is focused mainly to a design of a revolving positioner, which becomes a key element of whole workplace. Different design variants of inner most significant mechanisms are presented and by using sophisticated methods, the best solutions are chosen. Finally a simulation of whole robotized workplace is made and conclusions based on real implementation are summarized.

Development of Imaging Methods and its Importance to Biomechanics
Sedláček, Tomáš ; Houfek, Martin (referee) ; Florian, Zdeněk (advisor)
The main objective of this bachelor thesis is to collect all available literature, from which can reader obtain basic knowledge of imaging methods. The methods are divided by its origin into four categories: x-rays, magnetic resonance, ultrasound and nuclear medicine. Each of them is described from the historical, physics and technological view. At the end the importance of each method to medicine and biomechanics is summarized.

Using GreenGraffiti as an Additional Tool of Marketing Communication of the Company
Nešporová, Kristýna ; Sedláček, Tomáš (referee) ; Chlebovský, Vít (advisor)
Tato diplomová práce z oblasti marketingu zkoumá možnost využití alternativního reklamního média zvaného GreenGraffiti jako dalšího komunikačního nástroje. Protože je pro Českou republiku a tím i české klienty tento typ reklamního média nový, je důležité vysvětlit, co přesně GreenGraffiti je, odkud pochází a jak se objevilo v České republice. Tato diplomová práce bude také zkoumat, zda je GreenGraffiti vhodným reklamním médiem pro český trh ,a které problémy je třeba vyřešit před tím, než bude zařazen do komunikačního mixu společnosti. Tato práce je napsána na základě znalostí získaných během stáže ve Studio Tomato s.r.o., které vlastnilo licenci na GreenGraffiti pro Českou republiku a také na základě informací získaných od Jima Bowese, zakladatele GreenGraffiti Holding BV.

Retrofit steam turbine 210 MW
Sedláček, Tomáš ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This master‘s thesis deals with the retrofit of a three-body condensing steam turbine with an output of 210 MW. The first part deals with the thermal diagram, which is designed with seven unregulated steam extractions and one extraction for degassing. The mass flow is determined here on the basis of the required power and three thermal diagrams are made for different outputs. In the next part, the regulation stage in the A-wheel design was designed, including the strength control. The main subject is the design of the stage part, which is divided into preliminary and a detailed calculation relating only to the high pressure section of the steam turbine. During the optimization phase, a detailed calculation is linked to the thermal diagram and the regulation stage. The resulting blading of the HP section is optimized based on the selected properties, including strength control. An orientation design of the compensating piston together with the sealing system is also included, for selected diameters, due to the unknown action of the axial force from the MP and LP section. Furthermore, a strength check of the inner nodes of the existing body of the high-pressure section is performed, where the need to use the inner body arises. The designed HP section, including the regulation stage, achieves an internal power of 69,5 MW, an internal thermodynamic efficiency of 92 % and a reheat factor of 1,0168.

Waste Gasification
Sedláček, Tomáš ; Elbl, Patrik (referee) ; Lachman, Jakub (advisor)
The bachelor’s thesis deals with the topic of waste gasification. The first part includes the definition of waste with the focus on municipal solid waste, its evaluation as fuel on the basis of its contents and properties, in this case the heating value. Eventually the waste is compared with other normally used solid fuels. The second part presents and describes the thermal processes applied to waste-to-energy technologies, where the gasification is explained in more detail, its final products, the content of contaminants in these products and their removal. The next part deals with technologies used for waste gasification. The last part deals with the issue of waste gasification in the Czech republic.

Aspekty elektromobility v podmínkách evropského trhu
Sedláček, Tomáš
The bachelor thesis deals with the issue of electric vehicles in Europe. In the practical part, the closer attention was focused on the level of use of electric vehicles in comparison with cars with internal combustion engines. Furthermore, the thesis focuses on the issue of the development of charging points infrastructure along with the number of newly registered EVs. The price development of specific vehicles in relation to the demand for these vehicles has not been neglected. Finally, proposals are outlined that can lead to an increase in the availability and use of electric vehicles.
