Semiconductor utilization for the capture of ionizing radiation
Klus, Roman ; Varmuža, Jan (oponent) ; Radil, Lukáš (vedoucí práce)
This Bachelor’s thesis describes the types and characteristics of nuclear cells and analyses the interaction between ionising radiation and semiconductors. Semiconductor nuclear cells convert the radiation energy into electricity, while detectors utilise the semiconductors for measurement. The thesis introduces the reader to ionizing radiation, semiconductors, describes the nuclear cells and detectors. Then the betavoltaic nuclear cell and its components are described. The measurement and its evaluation is realised to prove the concept of semiconductor nuclear cell.

Big data analytics in the context of mobile network performance optimization
Klus, Roman ; Miloš, Jiří (oponent) ; Slanina, Martin (vedoucí práce)
This thesis focuses on big data techniques in the context of network performance measurement. The topic of big data and its utilization is being presented, followed by the research on basic network parameters, their measurement and evaluation methods. The RTR NetTest application, testing procedure and measured parameters are being evaluated. A set of tools was created for estimating the basic quantitative parameters of a mobile network on the basis of RTR dataset analysis. Time-of-Day Effect study concludes the time variance of the network. The spatial behaviour is evaluated by applying binning and clustering algorithms and in the end the comparison of drive test and crowdsourcing is provided.

Nuclear Cells
Klus, Roman
Nuclear cells are the devices converting the energy of ionizing radiation into electricity. This project describes the types and characteristics of nuclear cells. It introduces the reader to nuclear cells, their types and applications. Then the betavoltaic nuclear cell and its components are described. As the next step the available materials will be analysed and the measuring will be performed to check the functionality of the principle.

Big Data Analytics In The Context Of Mobile Network Performance Optimization
Klus, Roman
Crowdsourcing is a modern and growing technique of acquiring large amount of information. This project utilizes the data on mobile connectivity gathered by RTR NetzTest application to evaluate the performance indicators of the network. The software tool capable of assessing the network based on location, operator and other parameters will be created and utilized for benchmarking of the Austrian network operators. The software tool will be able to monitor the individual telecommunication nodes to estimate their performance in time.
