Electrolytes containing a phosphorus-based flame retardant
Pelikán, Ondřej ; Libich, Jiří (referee) ; Máca, Josef (advisor)
The diploma thesis is focused on the theoretical knowledge of lithium accumulators. More attention is given to electrolytes and especially to flame retardants, where the types and individual examples of flame retardants are described more detailed. The practical part is focused on the individual laboratory measurement of selected samples of electrolytes with different flame retardants. The measurement results are analyzed in other parts.

Fireplace inlay
Štelcl, Otakar ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
Bacheor´s work is divided into four main parts. First part deal with division of fireplace inlays according to material, construction of combustion chamber, combustion air, heat transmission and used grate. Second part deal with ČSN EN 13229. Majority part of work deal with problematic of measurement instruments, measurement section of combustion products and also with measurement of effectivity of fireplace inlay. Last part of Bacheor’s work speak about possibilities of optimalization effectivity in whole amount of power of fireplace inlay.

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.

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...
