Research of the effect of desicants on moisture adsorption
Němec, Mojmír ; Lisá, Hana (referee) ; Elbl, Patrik (advisor)
Desiccants are special materials that can effectively adsorb moisture from the surrounding air or space. Desiccants such as silica gel or molecular sieve are often used in laboratory applications, for example to determine the properties of solid fuels. The introduction of the research section is devoted to the description of these properties. The thesis then describes the methods used to accurately determine the moisture in solid fuels. The main part of the thesis is devoted to desiccators together with desiccants, which form a significant part in the process of determining moisture in solid fuels. The experimental part deals with the investi-gation of the effect of different desiccants on the rate of air moisture depletion in the desic-cator under laboratory conditions. The moisture loss in the desiccator is measured using the SHT4x Smart Gadget, which is placed in the desiccator together with the desiccant. The out-put of the experimental measurements are the moisture uptake rate curves of different desic-cants for desiccant weights of 50 g, 100 g, 150 g, 200 g and 250 g. At the end of the thesis, the measured curves of the different desiccants are compared with each other in terms of efficiency.

Heating Technologies for Household Heating
Krakovič, Vojtěch ; Elbl, Patrik (referee) ; Lisý, Martin (advisor)
This bachelor's thesis presents and compares the current options for heating family houses. The first part introduces the available heating technologies and types of fuels, explains the principle of their operation, shows the advantages and disadvantages, and for which type of building each type is suitable. It will gradually introduce heating with solid fuels, gas and electricity, and continue to heat pumps and methods of obtaining solar energy. The second part introduces a model house for which a suitable heating method is being sought. Heat losses and annual heat demand are calculated. After a short discussion of suitable alternatives, two suitable options are chosen, for which the approximate initial and operating costs, as well as payback periods, are calculated. The following is a comparison and evaluation, after which we will find out the most economically suitable heating method for the model house.

Enrichment and reprocessing of nuclear fuel
Janoušek, Petr ; Elbl, Patrik (referee) ; Sitek, Tomáš (advisor)
Nuclear fuel is one form of electricity generation. This bachelor thesis deals with its modification and processing as this fuel has to undergo special processes to ensure its good usability. The aim of the thesis is to list and analyze the main processes involved in the production of nuclear fuel. The thesis is, in particular, focused on the enrichment of nuclear fuel, which is the process of enhancing its properties. The first and second chapter of the paper discusses basic issues of first nuclear energy and then nuclear fuel. The third chapter of the thesis explains in detail the enrichment of nuclear fuel and also describes different methods of enrichment. Another process taking place after nuclear fuel is used is it's reprocessing. This method of converting used fuel into fuel that can be reused is dealt with in the last chapter of the thesis.
