Solar irrigation
Straňák, Rastislav ; Jaššo, Kamil (referee) ; Jandová, Kristýna (advisor)
This bachelor thesis deals with the issue of solar irrigation system together with the design and manufacture of the owner´s solution. The beginning of the thesis deals with the analysis of commercial equipment, determining its possible innovations. It continues with the analysis and selection of individual components for author´s solution. Newly designed device has a microcontroller that evaluates data from the relevant components, thus controlling the system processes. Thanks to the protection against self-destruction caused by running out of water or clogged hoses, the protection of plants against overwatering and the additive function of fertilization, i tis a compact solar irrigation system. The last part deals with the testing of the created equipment and the analysis of the achieved results.

Stability of aprotic electrolytes in lithium-ion batteries
Krištofík, František ; Máca, Josef (referee) ; Sedlaříková, Marie (advisor)
The Master thesis describe basic electrochemical processes in lithium-ion batteries and characteristic organic polar solvents for these articles. It focuses primarily on the aprotic liquid electrolytes for lithium-ion batteries and the subsequent use of gas chromatography to analyze the collected gas sample from the test article. For this experiment is, in this Master thesis, designed and described experimental arrangement in the form of a glass cell, which allows collection from the space above the working electrode. Finally, the work evaluates the effect of electrode potential on the stability of electrolytes in strongly positive potentials.
