Power to gas system
Urbánek, Štěpán ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis deals with Power to Gas system and its subcomponents. The first part of this thesis is research of the Power to Gas subcomponents. In the second part a balance model of the Power to Gas system is developed based on the traced technical parameters from the first part. The third part deals with traceable implementations of the Power to Gas system and the last part is the design of the system for home implementation.

Power-producing and Environmental Strategy of Czech Republic
Urbánek, Štěpán ; Brázdil, Marian (referee) ; Špiláček, Michal (advisor)
This bachelor thesis deals with energy and environmental strategy of Czech Republic. Part of this work is the description of international and intrastate documents which describes conditions and strategy objectives that not only our country must reach and fulfil them. Next is processed structure of the energy mix of Czech Republic and its predictable progress. In the next part of the work there is a characterization of possibilities how to produce electricity by renewable resources or nuclear energy and concept of using these sources in the future. The last part of the work contains prospect of reducing emission greenhouse gases.

Optimalization of the welding process for low - pressure tubular sets
Urbánek, Štěpán ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
The diploma thesis examines the implementation of the production process of low-pressure pipe sets for hydraulic aggregates in the company Bosch Rexroth. The first part presents a literature analysis of used technologies and basic welded materials. The second part focuses on selected subprocesses ensuring the production and proposals for their streamlining. It includes a summary of responsibilities across departments and a template for processing the necessary technical documentation for the smooth running of production. Another proposal includes a technological procedure for practical verification of the production, which simultaneously serves as a basis for measuring the welding time. The reason for the implementation of this production was the extended delivery time of pipe sets from suppliers and possible financial savings. The practical part is concluded with a technical and economical evaluation, which expresses the possible financial savings in the production of low-pressure pipelines instead of the current state involving the cooperation with suppliers.

Voskové směsi pro restaurování historických voskových pečetí
Bílková, Lenka ; Bartl, Benjamin ; Urbánek, Štěpán ; Zapletal, Martin ; Holakovská, Libuše
A large number of historic wax seals have been preserved in a fragmented state, which is linked to the increase in hardness and brittleness that sealing waxes undergo during natural ageing. The immediate cause of mechanical damage is careless handling or improper storage of archival records. This methodology compares the properties of both traditional and some alternative wax mixtures that are applicable for conservation of damaged seals. The aim is to highlight the advantages and disadvantages of using each of them, making it easier for conservators to choose a material that will meet their specific requirements. Chapter 2 first discusses the general requirements for such materials, from a technological, practical and ethical point of view. Chapter 3 deals with the properties of beeswax and the possibilities of their modification by the addition of other substances. Chapter 4 then discusses the new possibilities that open up the use of fossil wax mixtures. The chapters are supplemented by specific examples and recommendations.
