Measurement of clothing sets by means of thermal manikin
Hanzlík, Martin ; Toma, Róbert (referee) ; Fišer, Jan (advisor)
This diploma thesis is focused on the experimental determination of thermal resistance of the gloves and their combination in the layering system. The measurement was based on procedure specified in the standard ČSN EN 511 by means of thermal manikin. The thesis begins with the description of heat transfer mechanisms, description of glove materials and measurement methodology. The body of paper consists of the measured data analysis and equation design for determination of the glove layering system thermal resistance. At the end of the thesis, these equations are evaluated and it has been shown, that the thermal resistance of glove layering system cannot be precisely determined by the calculation, and it is necessary to measure the whole three-layer system.

Metane hydrate extraction
Hanzlík, Martin ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
Thesis describes the chemical and physical properties of methane hydrate, the presence and location of sites in various types of sediment. Goal of this work is to evaluate the proposed production methods of methane hydrate from the technological, logistical and economic aspects. With the technologies currently available, the best production method is depressurization. There is a high probability that in the next decade it will be used for the production of natural gas from methane hydrate. The conclusion is evaluating areas with high potential for industrial production.
