Thermal radiation in real life
Kalus, Petr ; Zálešák, Martin (referee) ; Klimeš, Lubomír (advisor)
This bachelor's thesis deals with the impact of heat transfer by radiation on the life around us. The research part summarizes the fundamental laws and concepts necessary for understanding the given issue. Furthermore, it describes and analyzes phenomena in everyday life where radiation is dominant. The greatest attention has been devoted to solar radiation, followed by the greenhouse effect, along with its influence on global warming. The thesis also includes a procedure for calculating heat transfer by radiation between two surfaces, based on which a Python script was written. Subsequently, a standalone application with a graphical interface was developed. The conclusion of the thesis focuses on describing the software development process and provides examples of test cases in thermomechanics.

Emise spalovacích motorů ve vztahu k životnímu prostředí
Cahová, Kateřina
This bachelor thesis concerned with emissions issue that arises during the burning of fuels in combustion engines, considering the environment. In introduction there are generally described burning fuels, then chapter about different types of fuels follows. The most important part of this thesis concerned with emissions having impact on the environment and possibilities of reducing their negative impacts on environment, atmosphere and human life. Also, it deals with analysis of individual data relating to emissions in the Czech Republic.

Methods of CO2 separation from air, ways of its use and long-term storage
Kober, Ondřej ; Baláš, Marek (referee) ; Škorpík, Jiří (advisor)
Combustion of fossil fuels creates greenhouse gas emissions that cause global warming. The most important of these gases is carbon dioxide. Although it occurs naturally in the atmosphere, human emissions upset the balance of various natural processes. The aim of this bachelor’s thesis is to conduct a background research in the field of carbon dioxide capture, storage and utilization. The thesis also describes the role of carbon dioxide in the atmosphere, its cycle and human influence on carbon dioxide concentration.

Preparation of laboratory exercise for school subject Ecology in Manufacturing
Balcárková, Lucie ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
The thesis deals with the design of laboratory task on selected topics and brings together theoretical knowledge needed to understand the principle and function of the proposed system. The theoretical design is elaborated from the point of view of physical principles, physical feasibility, electronic difficulty, user service, correctness of the system, and its economic aspect. Furthermore, the practical implementation of the chosen task is disscussed in detail, based on the collected theoretical knowledge, a comparison of the available options and the results of the measurements made.

Recognition quality of atmospere in towns and in areas with big resource of polluted air.
HRDÝ, Vojtěch
In this thesis, my objective was to determine the amount of air pollutants in cities of Ostrava and Ceske Budejovice and compare the differences of their content in the atmosphere of these locations. The theoretical part deals with the types of pollutants that occur in the atmosphere, their origin, characteristics and their possible toxic effects on the human body and the environment. Furthermore, there is an overview of the methods used for assessing air quality, prevention of air pollution and reducing the level of pollution, so as to reduce risks to human health caused by air pollution, to reduce the environmental burden substance reaching into the air and damaging ecosystems and create conditions for the recovery of components environmental affected by air pollution. To assess the air quality in both locations, I used the method of "secondary data analysis" of publicly available data published by the Czech Hydrometeorological Institute. From these data, I created graphs that compare the air quality in Ostrava in the Ceske Budejovice in the period 15. 8. 2016 - 15. 3. 2017 in all measured categories. For completeness, the work embedded graphs comparing the two cities on the 15th day of the month within a single pollutant. From the results it is evident that these two cities are in many ways similar. The assumption that the city of Ostrava is still a city with the worst air is no longer current.

The carbon footprint of households in South Bohemia
VOŠTOVÁ, Marie
The thesis deals with carbon footprint of households in South Bohemia, namely greenhouse gas emissions associated with the ordinary activities of each of us. The main objective of this thesis is to calculate the carbon footprint of households in the South Bohemia Region. The partial aim is then to assess which of the monitored components has the largest share of the total carbon footprint. These components are heating, electricity, cars, public transport, flying and food. Another partial objective is to compare the results in sociodemographic groups, which are residence, gender, education, age and income per person. The theoretical part explains the concepts such as global warming, sustainable development, ecological footprint, carbon footprint, and three already realized research on carbon footprint. The practical part describes the data acquisition, GILDED project, which was the inspiration for this thesis and method for calculating the carbon footprint. The main part consists of evaluating the calculated results, not overall carbon footprint, but also comparisons within categories of residence, gender, education, age, and income per person. The thesis finishes with the summary, which summarizes the most important results.

Measurement of greenhouse gas concentrations
Dohnal, Jan ; Vyroubal, Petr (referee) ; Bača, Petr (advisor)
This master thesis deals with the greenhouse effect, various gases and methods of measurement. On the greenhouse effect is viewed from its historical dating, despite changes in atmospheric composition. It contains a theoretical analysis of the individual gases. It focuses on the most harmful greenhouse gases such as water vapor, carbon dioxide, nitrous oxide, methane, ozone, chlorofluorocarbons and halons. Analysis methods for detection of gaseous substances. Part of this work is focus on the detection of nitrogen dioxide, chloro-fluorocarbon and methane. The data is processed using a ATmega’s microcontroller and then sent to an Internet server thingspeak.com. If the device proves successful, will be used as a laboratory exercise in the course Ecology in electronics.

Separation and storage of CO2
Odložilík, Martin ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The main objective of this work is to clarify the methods for CO2 capture and storage as an option to limit global warming. The first part is further explained by a phenomenon known as the greenhouse effect, there is illustrated his principle, the effects of climate change, the main factors increasing its intensity and its possible reduction. Framework of the second part is description of the technologies and methods of CO2 capture and storage, the individual steps in these processes and also the possible development in the future. Next chapter discusses the pilot research programs and application of referred technologies to in practice. The last part of this work is devoted to the economical aspect of the problems.
