Walls Between Us
Rodová, Eva ; Chovanec, Libor (referee) ; Mléčka, Jan (advisor)
This thesis deals with the creation of a conceptual system to address loneliness at the levels of households, streets, and communities. At the household level, it focuses on fostering strong connections among residents, while at the street level, it critiques the current trend of separating gardens from the street. Lastly, at the community level, it concentrates on establishing a quality center crucial for strengthening community bonds. This system is then applied across all levels in the municipality of Cejle. This municipality has lost its identity and center. Additionally, it features various types of houses, from historical structures primarily from the 18th century, through communist-era buildings, to contemporary ones. Thus, the municipality is an ideal candidate for implementing the system, as it allows for testing it on various types of constructions and addresses contemporary issues, particularly the lack of a quality center.

Long-distance belt transport
Řepa, Vojtěch ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
The bachelor's thesis deals with long-distance belt transport, the principles of which are explained in the first chapter of the thesis. In the following chapter, the individual components of the belt conveyor are described in detail. The practical part of the bachelor thesis deals with the conceptual design according to the specified parameters in accordance with ČSN ISO 5048 and the professional literature on the construction of belt conveyors. To verify the correctness of the concept, the strength of the selected conveyor belt is checked. A 3D visualization and drawing documentation of the conceptual design is created for the proposed concept.

Steam turbine for biomass power plant
Chumchal, Ondřej ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
This thesis deals with the design of a steam turbine for a biomass unit in two alternative solutions, with and without gearbox, for a given 30 MW clamp power. The design of both solutions works with the same heat cycle scheme, but the parameters at the low-pressure heater or at the inlet to the feed tank differ depending on the steam conditions in the turbine intakes. In the first part of the paper, a thermal balance scheme with low pressure regeneration is proposed and the steam flow through the turbine is calculated. Both variants have three unregulated bleeds, one of which is led to the degasification feed tank. For both variants a regulative stage is designed using impulse system of blading and a stage section using reactive blading. The work also includes the determination of axial force and the associated design of the balancing piston and gland steam system. Appropriate bearings were selected for the given force stresses. A graphical comparison of the two variants is presented in the paper, together with the operating characteristics. Finally, a conceptual section drawing of the steam turbine was made. The result is a turbine without gearbox with 36 stages and an efficiency of 82%, then with gearbox at 5400 min-1 with 27 stages and a thermodynamic efficiency of 86.7%.

Correction of the concept of drift in prediction models
Michálková, Eva ; Provazník, Valentine (referee) ; Schwarzerová, Jana (advisor)
The main goal of this bachelor thesis is the analysis of concept drift in metabolomics. Concept drift is an undesirable phenomenon and can be caused by nonstationary data. It can have a negative impact on the performance and reliability of predictive modelling. This challenge can be solved by concept drift detection and subsequent correction. One of the fields where this issue has recently emerged is metabolomic diagnostics. Metabolomic data analysis can lead to early detection of several serious diseases, which can help with the recovery process. When diagnosing an illnes predictive models present a way to make the process more efficient, faster and give the option of personalization. The first part of this thesis specifies concept drift, it’s detection and correction methods and the importance of metabolomics and prediction models. The second part deals with the implementation of some available algorithms for concept drift detection and correction and the implementation of automatic concept drift correction. Finally, in the second part results and their discussion are described.

Proposal to Introduce a Tax on Sugar in the Czech Republic
Lamačová, Markéta ; Brychta, Karel (referee) ; Semerád, Pavel (advisor)
This thesis focuses on the implementation of a sugar tax in the Czech Republic and evaluates the tax from the perspective of expected profitability. Attention is paid to the arguments for taxing sugar, specifically its negative impact on public health. The introduction of a sugar tax in the Czech Republic is based on the experience of selected countries, which have introduced a sugar tax. The effects and impacts of this tax have been compared and analysed. The result of the thesis is a proposal of sugar taxation under our conditions and the shortcomings occurring in the observed countries are eliminated.

Vehicle Hydropneumatic Unit
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis, following the bachelor's thesis, is devoted to the gas-liquid unit of a vehicle, as the central element of hydropneumatic suspension. The aim is to dimension and construct this component and integrate it together with other elements into a complex suspension system. Based on possible forms listed in the research section, regarding to current development trends, the form of the unit is chosen. The practical part begins with simulations comparing a hydropneumatic with a conventional suspension system. After solving this issue, it is possible to proceed to the dimensioning of the basic parameters of the unit and then to its construction, respecting the relevant strength calculations. The last step is to build a conceptual design of the whole hydropneumatic suspension system.
