Design of part machining including it´s assembly
Ryšavý, Radek ; Ohnišťová, Petra (referee) ; Kalivoda, Milan (advisor)
This diploma thesis is focused on piece production of the component and its subsequent assembly. It is an interchangeable spindle head marked VA1 from the product portfolio of TOS KUŘIM - OS, a.s. The aims of the diploma thesis include the characteristics of the assigned component, the subsequent analysis of the current manufacturing and assembly process. In the price calculations chapter, the direct and indirect input costs for the part production are quantified. Proposals to improve production were presented to the company and offered for possible implementation.

Plasma and microplasma welding
Ryšavý, Radek ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
The first part of the bachelor thesis is devoted to literary recherche, which describes plasma welding and microplasma welding. Here is explained the principle of these technologies, the types of burners and the gases that enter them. Comparison of advantages and disadvantages of plasma welding and microplazma welding. And consequently the industries in which these technologies are used. The second part is devoted to the comparison of two welds. These were made by similar welding parameters. For both welds the specific heat input was calculated. Subsequent metallographic macrostructure evaluation, which used to calculate the dilution of the weld metal. Finally, hardness measurements were performed in three areas of welding: basic material, heat-affected area and weld metal.

Castellan’s handbook: Methodology concerning due management of historical landmarks opened to public
Bidlasová, Lucie ; Bobek, Karel ; Bušta, Jaroslav ; Horyna, Tomáš ; Kadlec, Miloš ; Kunst, Lukáš ; Ryšavý, Radek ; Slavko, Pavel ; Weiss, Petr
The methodology is structured into separate chapters focusing on elementary topics of cultural property management. The preamble contains a short overview of historical development of historical landmark manager with international excursus and key words dictionary that would be appreciated by beginners unaware of the professional vocabulary. Main topics of management are: 1) Property management within the technical, organizational, economical and legal meaning. The subchapters formulate individual segments of various activities such as cultural and administrative assets evidence, employment relations, bookkeeping and budgeting. 2) Property safeguarding from securing it against theft to monitoring the artefacts microclimatic conditions. 3) Rehabilitation and maintenance of entrusted property especially emphasizing the realization of preventive solutions and providing a day-to-day care that results in continuity of historical values, methods and authenticity and in the end also significantly decreases the cost of maintaining the physical essence of the monument. 4) Presentation of cultural values to public, transmission of research outcomes and strengthening the cultural identity of society towards its history and values. The end of the text includes a crucial chapter focusing on planning and formulating of visions and conceptions of maintenance of concrete heritage areas. This part is extremely crucial as it is often overlooked. Sometimes from intellectual reasons but usually from a lack of time that is dedicated to operative solutions of concrete problems without an overall conception. These partial solutions are isolated with no linkup between them. The methodology urges the mangers to focus on conceptual activities and planning that will pay off in a long run.
