Use of the railway traction elements for distribution system support
Dékány, Michal ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
The bachelor thesis deals with the transition to a unified power supply system of the traction system of the Czech Republic. Describes the possibilities of using converters in various connections to improve the quality of electricity on the distributor side. The work presents current innovative solutions that use converters to support the distribution network by preventing the transmission of unwanted parameters from the traction network to the distribution network, such as higher harmonics, and also describes the possibilities of two-way power supply with their help.
Improvement of the Thermal Circuit of the Bioreactor and Its Verification
Lapčík, David ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The main idea of this bachelor thesis is a research of existing bioreactor solutions related to their practical implementation with different design, biomass composition, aeration modifications and heat exchange to recover heat from the process of aerobic composting. The conclusion of this work will be evaluation of the results of temperature measurements on functional prototypes depending on their properties and calculations of theoretical heat balance including their comparison.

Automatic Positioning for Solar Concentrator System
Čásar, Juraj ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The aim of the work was to create an automatic positioning system, with optics for radiation concentration and a body for its collection, by monitoring the sun across the sky using a camera. At the beginning are introduced the concentrator systems and the movement of the sun from the perspective of the observer. Follows description of the various potential components which requires a functional system. The last part deal with the implementation of selected components for operation as a whole system, verification of functionality by accurate tracking of the sun across the sky and measuring the performance of the concentrator system with automatic positioning.
