Storage systems for renewable energy
Šebek, Denis ; Linda, Jakub (referee) ; Poláčik, Ján (advisor)
The accumulation of energy by hydrogen technologies is an important topic for the advancment of energetics in the future. This thesis is based around different methods of accumulation of energy including acumulation of energy by hydrogen technologies. Furthermore, the thesis describes methods of hydrogen storage, its advantages and disadvantages, and the overall principle. In the last part of the thesis, a hydrogen accumulation plant is designed, which uses electricity from renewable sources as its energy source.

Machine learning in water machine diagnostics
Šebek, Denis ; Rudolf, Pavel (referee) ; Habán, Vladimír (advisor)
The thesis focuses on utilizing high-frequency measurement methods for measuring pressure, sound, and acoustic emission, and their application in machine learning for detecting operational states in water machinery. This thesis aims to propose a machine-learning approach capable of evaluating cavitation, flow conditions, and faults based on the collected data. The first part of the thesis discusses the theoretical introduction to selected high-frequency measurement methods and provides a basic introduction to machine learning. The second part describes the experimental setup, including data preprocessing and the implementation of a neural network. In the conclusion, the individual results are evaluated and compared.
