Vertex and Pixel Shaders for 3D Visualization of grass
Dokoupil, Martin ; Chudý, Peter (referee) ; Kršek, Přemysl (advisor)
This thesis describes the way to create three-dimensional visualization of grass in computer graphic. Contains progress of grass visualization from past to present. Contains shader intro and its use for visualization. Text mention scene graph which has been used for implementation. Text describes three levels of detail and implemetation of waving grass. Text compares frame speed for each level of grass and frame speed for complete visualized grass.

Web Collaboration Platform for Activists
Kabelka, Jiří ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The goal of this thesis is creating a web collaboration platform for connecting ecologically oriented activists containing tools for finding suitable collaborants and subsequent project management. The platform is built using the Model-view-controller architectural pattern. The platform is using the PHP Framework Laravel for server side communication and a MySQL database for data storage. The platform user interface is built using the CSS library Bootstrap, Blade templating engine, Sass compiled using the webpack module bundler and native Javascript with jQuery library.

Condensing steam turbine
Krška, Jan ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
This master’s thesis deals with the design of a condensing steam turbine for certain parameters. In the initial part of the thesis, a research on steam turbines and types of blading is carried out. The computational part of the thesis is divided into several subchapters which have been made into larger chapters. One of the chapters deals with the thermodynamic calculation of the flow section of a steam turbine for a clamp power of 5 MW, a speed of 11,000 min-1 and a pressure of 0,1 bar (a). The calculation has been optimized for several basic operating parameters that the steam boiler is capable of achieving with respect to the highest possible thermodynamic efficiency of the plant. The work includes the evaluation of the results in the form of a graph. After the calculations for all steam parameters have been performed, the point was selected which with it’s values meets the requirements for the highest thermodynamic efficiency. The optimum operating parameters of this turbine are such that the turbine at a nominal temperature of 490 °C and an operating pressure of 65 bar (a) achieves a clamp power of 5190,220 kW. The thermodynamic efficiency of the steam turbine is 85,07 % and the reheat factor is 1,0634. Subsequently, basic dimensioning calculations were performed. The calculations are followed by a chapter entitled discussion where some important steps are evaluated. The master’s thesis also contains an appendix. It is a conceptual longitudinal section of a steam turbine.

The design of Pelton turbine for given parameters
Pavlíček, Tomáš ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
The aim of this bachelor's thesis is to create a project of a small Pelton’s turbine for laboratory use, focusing on the design of nozzle and blade. Designing these two parts included beam measuring, calculating the losses in the piping and finding the working point of the pump. In its first part this thesis reviews the history, the operating principle and the main parts of the Pelton’s turbine. The next part includes finding the appropriate shape of nozzle and measuring the beam, followed by the calculation of lossy coefficient and efficiency of the nozzle from the measured values. The third part is dedicated to calculation of losses in the piping and finding the working point of the pump. In the last part, blade is designed.
