Alternative methods and algorithms for flame detection
Kozubík, Kamil ; Dřínovský, Jiří (referee) ; Frýza, Tomáš (advisor)
This master’s thesis deals with flame detection methods. The purpose of the project was to create a flame detector, which uses the alternative method of flame detection. The introduction of this thesis gives the summary overview of the existing methods for flame detection. Further, the existing flame detectors and their applications are described. Two alternative algorithms for flame detection which are based on the digital signal analysis were realized on the PC. Flame detector, which utilizes the digital analysis of audio signal, was realized on 8 bit microcontroller Atmega128 and achieved results are presented.

Copy Protection of CD and DVD
Řehák, Lukáš ; Říha, Zdeněk (referee) ; Cvrček, Daniel (advisor)
This bachelor thesis is about the CD anc DVD copy protection, its discription, classification and testing. It also focuses on the quality of the protections, frequency of use, possibility of succesful copying and other properties of these protections. Then it discusses the reasons for using these protections.

Vliv vypalování pastvin na lesní zdroje republiky Zambie
Šanda, Matěj
The aim of this bachelor thesis is to evaluate the loss of forest in Zambia, in a marked locality in the southern province. For the purpose of this research, we used satellite images of the Sentinel 2 satellite, which we subsequently edited in the ArcGis map software so that differences in vegetation and it´s loss can be seen on individual images that are separated by 5 years. Another question is the use of fire as a tool for creating new areas for agricultural and grazing purposes, because Zambia is one of the countries in which fire plays an important role (it deeply affects both the historical and cultural roots of this country). It is very problematic to find a suitable and ecological substitute for burning.

Study of the difference between natural gas and hydrogen combustion
Winter, Josef ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis deals with the combustion of natural gas with hydrogen in certain volumetric concentrations. The change in physical parameters due to the addition of hydrogen, which differs in its properties from natural gas, was studied. The thesis is divided into a research part, where the properties of natural gas and hydrogen are described, including a comparison with each other, the effects of gas properties on flame, emissions, or temperature. In the second part, a calculation for the fireplace with chosen dimensions was performed and the changes in physical properties due to the addition of hydrogen were observed and the findings are summarized, which will have to be considered in the design of the fireplace. All calculations are added to the appendices.

Fire Education and Chemistry at Elementary School
Friedlová, Eliška ; Bílek, Martin (advisor) ; Koperová, Dominika (referee)
The bachelor thesis focuses on the issue of fire education in elementary school and the School's fire protection obligations in relation to the teaching of chemistry. The risk of fire or other dangers is pervasive and can be encountered anywhere. What is important is preventative educational activity already in children at school age, to the extent that everyone can prevent a fire or other accident and respond adequately to it at the outset. The theoretical part is focusing on the characteristics of the connection of fire safety and protection to education at lower secondary education. It contains an analysis of available documents, including curriculum documents (Framework Educational Programme for Elementary Education and selected School Educational Programmes, chemistry textbooks, and other methodological materials) and topics of chemistry instruction that are closely related to fire safety and protection. The practical part, which contains teaching activities for students with topics related to fire safety and protection suitable for lower secondary chemistry education, are prepared or adapted. The prepared materials were reviewed by group of teachers and other experts in the field and their evaluation shows that the prepared materials are beneficial for the current practice of primary school...

Vliv požárů na psamofilní vegetaci jihovýchodní Moravy
ŠÍMOVÁ, Štěpánka
The influence of a large accidental summer fire and experimental burning in different seasons on psammophilous vegetation was studied. Vegetation characteristics were described before and one year after the fires. There were determined which treatment supports occuring of target species of psammophilous grasslands and if prescribed burning can be used as a tool of management in nature conservation.

Case study of physiotherapeutic care for a patient with the diagnosis of 2nd and 3rd degree burns of hands and the head
Purchartová, Dana ; Pánek, David (advisor) ; Křížek, Tomáš (referee)
Title: Case study of physiotherapeutic care for a patient with the diagnosis of 2nd and 3rd degree burns of hands and the head Summary: The aim of this work is to obtain a comprehensive overview of the problems of burns and the medical and rehabilitation process of this diagnosis. The work is divided into a general and special section. The general part includes the anatomy and physiology of skin, the definition and pathology of burns and the possible methods of treatment focusing on the use of physiotherapeutic care. The special section includes the methodology of work and uses a case study to deal with the anamnesis, the input kinesiologic analysis, the course of therapeutic units, the output kinesiologic analysis and the evaluation of the effect of the therapy on the particular patient. Key words: burn, burning, skin, rehabilitation, physiotherapy, case study

Natural biomass burning and character of emissions of these processes
Maňo, Martin ; Köbölová, Klaudia (referee) ; Chýlek, Radomír (advisor)
This bachelor thesis deals with the issue of emissions from natural biomass fires. Emphasis will be placed on aerosol emissions that occur during these natural phenomena. The introduction will discuss in general the natural fires of biomass in the world and their impacts. The next part of the work will investigate the factors that affect the composition, size and composition of aerosols, as well as their impact on living organisms and the environment. Methods will also be described for determining whether an aerosol trapped in the environment is of anthropogenic or natural origin. In the last part, the author will deal with the analysis of data from the measurement of real biomass combustion, in which he will participate
