Modeling of solar power station parameters in GIS
Kučera, Josef ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The work deals with the modeling of the parameters of solar power plants and the issue of solar energy with its use in the photovoltaic power plants. It uses the geographic information system named ArcGIS. In the beginning of the work, there is the theory. This theory is necessary to understanding the function of the photovoltaic cells, from the beginning to the photovoltaic panels construction. There were analyzed the conditions of the location of the photovoltaic panels in the Czech Republic. Furthermore, the work approaches the ArcGIS and its 3D modeling possibilities. The part of the work deals with the proposal for the selection process of the most suitable location to the photovoltaic panels installing. The main part of the work is the visualization of the 3D models of the locations of interest.

Automated design and 3D printing of prototypes for urban engineering
Krutáková, Anna ; Vořechovská, Dita (referee) ; Podroužek, Jan (advisor)
This bachelor thesis deals with automated design and 3D prototype printing for urban engineering. In the first part, there is a general definition of 3D printing, including development and overview of basic technology and materials. It also follows the focus on certain measurement methods and the creation of 3D models. In the second part, the thesis focuses mainly on the use in the building industry and it discusses related topics such as the automatic optimization of the external elements of building elements or objects(shape), the internal topology of these building elements (fill) and the possible inspiration from organic structures. There is also distinguished between terrestrial applications focusing on the production of prefabricated building components and implementation at site. Extraterrestrial autonomous applications discuss the possibilities this technology for colonizing the Moon or Mars. This thesis presents the results of a unique assessment of the current state of the art in the field of applicability of 3D technology for additive production in the context of urban engineering and demonstrates the associated advantages and open problems on many examples. Finally, the benefits of this technology are evaluated.

Computational simulation of the compression test of the open cell metal foam
Homola, Václav ; Skalka, Petr (referee) ; Ševeček, Oldřich (advisor)
The thesis presents computational simulation of compression test of a nickel foam and the 3D reconstruction of micro-CT images was utilized to generate the foam’s model of geometry. Explicit FEM is used to simulate compression test using software tool LS-DYNA and the stress–deformation curve is obtained together with deformed model’s mesh used for subsequent analysis. Sensitivity analyses were performed to configure the model and ensure best fit with values obtained during real-life experiment. The ANSYS Classic environment was then used to simulate tensile test of the foam compressed to various thicknesses. The tensile moduli in three mutually perpendicular directions of nickel foam were computed and the results were compared to experimental values as well. The results of tensile test simulation revealed considerable anisotropy of the foam’s elastic behavior. It can be said that the measured experimental data correspond very well with the elastic properties obtained from simulation up to certain level of compression. Analysis of the relationship between the element size and tensile moduli showed a significant difference between fine and coarse mesh. The optimal level of discretization and the overall model configuration ensuring high level of accuracy is proposed in this thesis.
