Static analysis of railway bridge
Bureš, Vojtěch ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis deals with the static analysis of a railway bridge. Using AxisVM X6 software, I created 4 different models and compared them not only with each other, but also with simple manual calculations. Two models are beam models, the third is shell model, the fourth is also shell but with an end ledge that reinforces the entire structure. The structures are loaded by a manually calculated load according to the standard.

Production and characterization of biochar from mixed plant waste
Bureš, Vojtěch ; Nábělek, Jakub (referee) ; Pořízka, Jaromír (advisor)
This work focused on biochar production from mixed vegetable waste in the context of home gardens and small farms. The aim of the work was to produce different types of biochar from common mixed garden waste material and then to characterize it according to the European Biochar Certificate (EBC) classification, as well as to develop a methodology for household biochar production, according to current knowledge. Four of the five biochar samples produced met all the criteria for the EBC-Feed category and are therefore suitable for any form of use, including animal feed production. The last sample did not meet the EBC parameters for usable biochar due to above-limit levels of polycyclic aromatic hydrocarbons (PAHs), but according to current studies and the new European Union limit values for fertilisers and amendments, the detected PAHs concentrations do not prevent its application to agricultural land. Therefore, based on the findings of this work, it is possible to recommend domestic production of biochar and its application to agricultural soils for long-term improvement of soil quality.
