Slab bridge
Malý, Jan ; Muroň, Vlastimil (referee) ; Panáček, Josef (advisor)
Bachelor's thesis deals with the design of a road bridge over the Volyňka river. Three bridging variants were proposed, of which the bridge variant, whose supporting structure consists of an additional pre-stressed concrete slab, was chosen for subsequent detailed assessment. The variation with prestressed prefabricated girders with composite slab is chosen for more detailed assessment. Detailed structural design is made and selected parts of the construction are checked for ultimate and serviceability limit state by Eurocode. Calculation of load is made by manual way and then by exact way with program Scia Engineer 22. The results from both calculation methods are then compared. Detailed drawings and visualization are made as well.

Water Surface Visualization
Kliš, Michal ; Vlnas, Michal (referee) ; Starka, Tomáš (advisor)
The aim of this work is to investigate and implement methods for real-time simulation and visualization of large water bodies. The knowledge gained from the research is further exploited in the implementation of a specific application used for ocean simulation. Among the methods discussed is the spectral method. The text will offer the reader, in addition to the actual introduction to this method, various insights to focus on in its implementation.

Boundary layer transition visualization in aerodynamic tunnel
Holík, Denis ; Trusík, Vojtěch (referee) ; Popela, Robert (advisor)
The purpose of the thesis was to propose and test an imaging method that allows visualization of the transition of a laminar boundary layer to a turbulent one and visualization of laminar boundary layer separation on the side mirror of a car. The beginning of the paper discusses the theoretical foundations associated with boundary layer formation and its evolution under various conditions. Afterwards, a survey of existing imaging methods that allow the display of flow on the surface of bodies was carried out. Of these methods, imaging using a thermal imaging camera was selected on the basis of the specified characteristics. The method using oil film (oilflow) was chosen as a control. Using both methods, experiments were conducted to confirm the suitability of the thermal imaging method for visualizing the transition of a laminar boundary layer to a turbulent boundary layer. The final test revealed the presence of laminar boundary layer separation on the upper cover of the car side mirror. At the end of the thesis, possible errors associated with the two chosen visualization methods were summarized, and ways to incorporate the thermal imaging method into automotive testing were proposed.

The effectiveness of mind-mapping learning strategy to extend vocabulary knowledge among elementary students
Šnevajsová, Helena ; Mikuláš, Martin (advisor) ; Kacafírková, Petra (referee)
Knowledge of vocabulary is an essential part of linguistic competence. Many students learn English vocabulary by translation and rote memorisation of vocabulary lists, which can result in the inability to use the words in well-formed sentences and appropriate contexts. Some students may find rote memorisation monotonous. This study examines the effectiveness of using the mind-map learning strategy to extend English vocabulary. Thirty-one elementary school students (15 men and 16 women) from two different elementary schools completed a short test before vocabulary instruction to obtain baseline data. Vocabulary instruction with the use of mind maps learning strategy followed. The recall was measured at the end of the lesson and one to two weeks after vocabulary instruction. A subjective assessment of the mind map learning strategy to learn vocabulary was taken. The results show that the knowledge of vocabulary items improved compared with the baseline. Moreover, students retained similar knowledge even after one to two weeks. New information was moved to the long-term memory of the students. Students were able to recall vocabulary from a medium- term perspective. Subjective assessment of the learning strategy showed that students enjoy learning vocabulary with mind maps more than writing vocabulary...

PLC Control of Mobile Robotics Platform
Konečný, Michael ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
The aim of this master's thesis was to create a design for a prototype of a mobile robotic platform and its physical fabrication. Another goal of this master's thesis was to develop a control algorithm and its implementation into a prototype. In addition, the thesis was extended by an autonomous motion mode, an algorithm for robot path planning, and the design of the Human Machine Interface (HMI). The introduction contains a description of some already created mobile robotic platforms, a presentation of the company B&R and the theory needed to understand omnidirectional mobility. The next chapters describe the design and construction of a prototype with a selection of electronic components and their wiring, implementation of an algorithm for robot path planning, implementation of a control algorithm and design, together with the implementation of the user environment. At the end of this master's thesis, the possibilities of extending the project to future years are described.
