Study on the potential of an integrated waste-to-energy unit
Freisleben, Vít ; Turek, Vojtěch (referee) ; Jegla, Zdeněk (advisor)
This diploma thesis is focused on the design of technological modifications of the existing industrial unit „waste-to-energy“, used for thermal treatment of process waste gases containing VOC and CO while flue gas is produced. The main objective of the existing unit modification is to improve its operating parameters considering economy, ecology and energy utilization. In the first part, the current industrial plant was presented with all necessary process data. Furthermore, all the key equipment used for the waste gases treatment or for the utilization of waste heat was identified. In the main part of the thesis there are performed modifications of the existing unit including the technology of existing heat exchangers intensification, the design of new and more efficient heat exchangers and finally the catalytic oxidation technology implementation for the decomposition of pollutants contained in the waste gas. The result of the thesis is a technical, economic and ecological comparison of the proposed technological modifications with the existing operation.

The Business Plan for Establishing of Small Company
Halouzková, Radana ; Bumberová, Veronika (referee) ; Koráb, Vojtěch (advisor)
This thesis deals with the issue of establishing a real and competitive business in the field of not only psychic but also physical health. The foundation of the project is a well-designed business plan. The business will deal with regenerative and nutritional activities through all kinds of exercise, massage, physiotherapy and nutrition counselling, and will serve sportsmen as well as the general public. In the thesis were used well-known analyses such as Porter's Five-Strength ůnalysis, PEST ůnalysis, SWOT ůnalysis and Qualitative Research Survey. The aim of this thesis was to create a business plan that would be competitive and offer services that people are interested in.

Stirling Engine
Vondruš, Jan ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor thesis deals with the description and calculation of a closed regenerative thermodynamic cycle. In the theoretical part of the thesis, there is described history of the engine, the principle of its function, differences between particular design variants, and the use of the engine in the past and nowadays. In the other part of the work, there is described the principle and calculation of ideal Stirling cycle. In addition, there are included positives as well as negatives of applying the heat devices based on this cycle. Practical part of the work deals with the calculation of ideal Stirling cycle with the use of Schmidt theory. The primary aim of this bachelor thesis is then to compare and contrast the results gained from both of the calculation methods. In the end, the results of the thesis show that the use of Schmidt theory gives lower, i.e. more accurate, values of engine's parameters compared to the use of Stirling ideal cycle.

Experimental support for the development of specific integrated equipment
Hrbáček, Jiří ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
Regenerative heat exchangers are used in a wide range of industries and in the technical equipment of buildings. These heat exchangers play an important role in saving thermal energy and removing volatile organic compounds from flue gases. The theoretical part of the work deals with the division of regenerative exchangers into rotary and switching exchangers and the possibilities of their use. These types of heat exchangers are used in many applications, e.g. as a heat exchanger using waste heat to preheat the process gas (regeneration layer), or as catalysts to accelerate the reaction required to remove volatile organic compounds (catalytic layer), or as integrated equipment where both the regeneration layer and the catalytic layer. The aim of the diploma thesis is experimental support in the development of a computer program for the design of a specific integrated device. The program allows the calculation of the regeneration and catalytic bed, or both beds simultaneously, i.e. integrated equipment. The diploma thesis deals with the support of a mathematical model for the calculation of the regeneration bed. Pressure loss and heat transfer play an important role in the selection and subsequent calculation of a suitable bed. To calculate them, it is possible to find more available computational relationships that differ significantly in their accuracy. It is therefore necessary to select the most suitable ones for the computational model. The practical part of the work then deals with research, analysis, and assessment of the suitability of methods used to calculate pressure losses based on a comparison with the values measured on experimental equipment. Subsequently, the work deals with computational methods for determining the heat transfer coefficient of the packed bed. A significant part of the practical part deals with the modification of the experimental equipment for the verification of computational relations for the determination of heat transfer with measured data.

The panel housing estate Brno Bohunice - public space and its sustainability
Spilková, Klára ; Tichý, Jan (referee) ; Pavlovský, Tomáš (advisor)
This Diploma Thesis deals with the panel housing estate Brno Bohunice built in 1972 – 1989. A special attention is devoted to public space between the Moldavska and Ukrajinska streets. The theoretical part of the diploma thesis outlines the history of panel housing estates from their inception to the present. Further, it deals with public space and regeneration of panel housing estates. There follows an overview of the panel housing estate Bohunice and its brief development. The practical part focuses on an analysis of the selected area. On this basis the urban concept of regeneration of the defined area is articulated. The aim of the proposal is to create functional and sustainable public space in the area of the panel housing estate Bohunice. Ideally, this work could become a basis and impulse for the regeneration of public spaces in the Bohunice housing estate, as well as in other panel housing estates in the Czech Republic. The aim of the thesis is to outline the complex issues of public spaces of panel housing estates and the possibilities of their improvement.

Economics of brownfields regeneration
Lukele, Petra Elly ; Pospíšilová,, Barbora (referee) ; Hromádka, Vít (referee) ; Špirková,, Daniela (referee) ; Korytárová, Jana (advisor)
The dissertation thesis focuses on the economic view of interventions in the extensive brownfields, ie uninhabited parts of cities, abandoned halls, buildings, industrial zones. It monitors the factors influencing their regeneration, deals with ecological and related financial issues. It examines the possibilities and ways of financing the recovery of these abandoned and unused areas. The work demonstrates the suitability of using the CBA method to determine the economic efficiency of brownfields regeneration projects. Whether the regeneration of brownfields is economically efficient, establishes a new indicator cef as the difference between the financial and economic profitability of the project. The work verifies the suitability of using the indicator on a research sample of 28 implemented brownfield regeneration projects. At the end of the thesis, the expected value of the social benefit of Monte Carlo is determined with the support of the Crystal Ball simulation software.

Old - new urban spa
Vítek, Filip ; Kolouch, Jiří (referee) ; Hrabec, Josef (advisor)
The project is aimed on the solution for an old, funcionalist winter spa in the city of Brno. The conception implements contemporary spas taking inner physical environment into account. The desing also offers new alternative for racing swimming pool and a substitution for unsuitable Boby swimming pool in the future. People can experience complete renegeration process from swimming, over whirpool and steam bath, to calm stretching places and professional physiotherapist assistance.
