Synthetic and alternative fuels for internal combustion engines
Kromp, Miloš ; Zeizinger, Lukáš (referee) ; Böhm, Michael (advisor)
The bachelor’s thesis focuses on synthetic and alternative fuels for combustion engines. Types of fuels, production and distribution processes, and their impact on combustion and engine performance are examined. The work also analyzes the impacts of these fuels on CO2 emissions. An innovative part is the usage of a simulation model of the engine, which allows comparison of performance parameters and emissions when using different types of fuels. This method brings new possibilities for optimizing the use of alternative fuels.

Study of behavior of thermal insulation materials on natural base
Kostlánová, Jana ; Balíková, Jitka (referee) ; Zach, Jiří (advisor)
The aim of the thesis is focused on a research of behavior of thermal and acoustic insulating materials on natural base with major importance on fibrous insulating materials. Vital part of the thesis is aimed on monitoring of environmental aspects interrelated with retrieving of raw materials and insulating materials manufacturing. Other types of fibrous insulating materials employed in a civil engineering are presented in the text. The main objective of the thesis is an evaluation of an influence of input fibers quality to the final attributes of insulating materials. The fundamental element of material quality evaluation represents physical and mechanical attributes of examined subjects.

Methods and technologies for carbon dioxide capture in industrial plants
Rek, David ; Máša, Vítězslav (referee) ; Sukačová, Kateřina (advisor)
The rising level of carbon dioxide in the atmosphere has negative effects on life on our planet. Humanity is now dealing with the issue through multinational organizations which attempt to motivate the current industry to develop innovative solutions to increase the energy-efficiency while lowering the amount of produced emissions. The most affected are energy-intensive sectors of the industry, such as the ceramics industry. This diploma thesis is based on a thorough research conducted on scientific literature, mainly scientific articles. The theoretical part is to familiarize one with the issue of rising levels of carbon dioxide. Next, methods to capture, store and use the gas are presented. Furthermore, the thesis focuses on one such method – microalgal bioreactors. The practical past weighs the usability of microalgal bioreactors for the purpose of carbon dioxide emissions capture in a production company LASSELSBERGER, s.r.o. belonging to the ceramic industry. Tubular bioreactor with a volume of 2000 m3 would process 3,75 % of CO2 produced by the core production machine – spray drier, during this process 367,92 tons of microalgal biomass would be produced annually.

Ekonomické a ekologické aspekty elektromobility
Otáhalová, Barbora
The bachelor thesis deals with the dependencies of economic and ecological factors in the field of electromobility in European countries for the year 2021. The literature review characterizes electromobility, briefly describes its development, current status, as well as advantages and disadvantages. Furthermore, a comparison of certain factors between European countries is presented in this chapter. The theory of regression analysis and the stages of econometric modelling are also included in this study. The practical part includes creating and testing two econometric models. The results show that there is a positive dependence between GDP, the number of charging stations and the number of newly registered electromo-biles. Another sub-result is the confirmed dependence of newly registered EVs on the reduction of CO2 emissions.

Hodnocení výstupních parametrů elektomobilů
Diviš, Ondřej
The diploma thesis is devoted to the evaluation of the output parameters of electric cars. In the first part, they are described in detail individual construction solutions of electric cars and hybrid vehicles. Another section deals with the main advantages and disadvantages of individual construction solutions. Furthermore, they are outlined here possible development directions in the field of electromobility. The practical part of the work deals with the measurement of acceleration depending on time and the course of the increase in speed during acceleration in electric cars and vehicles with an internal combustion engine with an automatic transmission. The results showed that electric cars have better acceleration characteristics than vehicles with combustion engines with automatic transmission. In the case of electric vehicles, a linear increase in speed occurs, whereas in the case of internal combustion engine vehicles, an uneven increase in vehicle speed over time can be observed further during the reassignment of individual gears. As part of the evaluation of driving modes, it was also found that all vehicles achieved the best acceleration characteristics in the "Sport" mode.

Vplyv ekonomického vývoja na emisie skleníkových plynov v EÚ
Muchaničová, Júlia
Muchaničová, J. Influence of economic performance on greenhouse gas emissions in EU. Thesis. Brno: Mendel university in Brno, 2023. The diploma thesis focuses on the identification of economic determinants, which influence CO2 emissions and thus also on the fulfillment of the relevant goals of sustainable development. The analysis is created through indicators such as gross domestic product per capita, energy consumption, crude oil prices and foreign trade. The first part of the work deals with an overview of the literature on the given topic. The issue of sustainable development and the relationship between economic growth and the quality of the environment is summarized. The empirical part consists of three chapters. A general model, the Environmental Kuznets Curve model, and also will be created the analysis of the lag of economic growth on the environment.

Living by the river
Malahefji, Tarek ; Kubínová, Šárka (referee) ; Wittmann, Maxmilian (advisor)
The city of Brno is the capital of Moravia in the Czech Republic which was shaped by many historical events, its predominant textile industry was amongst the most important aspects of these criteria, since its main rivers cut through the city (Svratka, Svitava), this industry and its trade, was a main factor in shaping the city as a whole, alongside political conflicts, change of regimes. During the 1960s, after the planned style economy was settled completely, it resulted in big setbacks for the Czechoslovak economy, as the textile industry started to crumble. The final blow to this industry happened after the velvet revolution as privatization took place and most remaining factories were dismantled. This narrative had a big role in shaping how Brno looks today as the northern part of the city is more urbanized than the southern part which is more industrialized by nature, and unlike Prague, these two main rivers are not widely crucial to the public life. This also developed along with other factors a major problem with accommodation quality, price as official data reports increasing dissatisfaction from inhabitants with housing.
