Optimization of Light Jet Aircraft Air-brake Bracket
Kopecký, Marek ; Maňas, Pavel (referee) ; Koutný, Daniel (advisor)
The master thesis deals with a design of an air brake bracket for a light jet aircraft. The shape of the bracket was topologically optimized and manufactured using Selective Laser Melting technology using the AlSi10Mg material, resulting in a 37% reduction in weight. The component was verified using FEA. The real prototype was destructively tested to determine its behaviour and then was compared with the FEA simulation. The testing also confirmed that the bracket complies with the given load conditions and has almost five times greater load capacity compared to the operating load. The new design of the lightweight bracket will increase the range of the aircraft and reduce the carbon footprint.

Evaluation of Business Performance Through Financial Analysis Tools
Kopecký, Marek ; Heralecký, Tomáš (referee) ; Ptáček, Roman (advisor)
This bachelor thesis deals with the evaluation of the performance of the company Choceňská mlékárna s.r.o. for the period 2018-2022 and subsequent proposals for improving its financial situation. The thesis is divided into four main parts. The first one is devoted to the objectives and methodology in its preparation. This is followed by the theoretical part, which is aimed at explaining the important tools, indicators and procedures of financial and strategic analysis. In the third part, the selected company is first introduced and then an analysis of its current state is carried out, which is the basis for the fourth and final part. The latter includes the actual proposals of measures and solutions that should improve the financial performance of the enterprise.

3D print of gearbox housing model
Kopecký, Marek ; Rebenda, David (referee) ; Dočkal, Kryštof (advisor)
This bachelor thesis focuses on the design of two stage spur gearbox housing for food processor. Strength calculation was conducted using FEM analysis. State of the art from the field of transmission casing, CAD model and prototype created by 3D print are parts of the thesis. 3D printed model is meant for demonstration of bearing seats and use of normalized mechanical elements. The thesis should provide fundamentals of gearbox housing and show a solution of one case.

Revitalization of the building -Jaroměř
Kopecký, Marek ; ing.arch.Klvaňa Jiří (referee) ; Eliáš, Luboš (advisor)
The project prepares reconstruction of old factory hall for new elementary music school in Jaroměř. The building is located in the city center with good transport links. Maintaining existing supporting steel structure and masonry perimeter walls allows generous use of space and innovative internal structure. Building equipment includes all fields of art and is designed for a capacity Jaroměř city and vicinity. Thanks jednopodlažnímu solution is an object conceived as partially disabled. Documentation is prepared on the documentation for building permit.

Transformations of Ontologies
Kopecký, Marek ; Škoda, Petr (referee) ; Dytrych, Jaroslav (advisor)
This master's thesis describes importing the ontology in language OWL 2 into the internal structures of 4A annotation server. It is concerned in anonymous nodes, for example in anonymous classes or anonymous properties. The solution was to use the library The OWL API for import ontology. The solution also allows automatic generation of names to anonymous classes and properties.

Rendering of Terrain and Water Surface in a Computer Game
Kopecký, Marek ; Kajan, Rudolf (referee) ; Herout, Adam (advisor)
This bachelor's thesis deals with rendering of water and terrain, which is a key part of many computer games and simulations. The resulting application runs fluently and is powered by XNA Framework. Rendering of terrain includes multi-texturing and lighting. The water simulation includes reflection and refraction of ray on water surface. Foam is rendered on the bank of water. Water waves are computed using the inverse discrete Fourier transform.

Environmental aspects of the cultivation of selected energy crops
KOPECKÝ, Marek
This dissertation aims primarily at determining the energy yield that can be produced, if certain species of energy crops are grown (under various regimes of fertilizing and sowing) by the Faculty of Agriculture, the University of South Bohemia, on a university's trial parcel. Zea mays L. is one of the energy crops chosen for the experiment; it is grown on a large area in the Czech Republic nowadays. Perennial crops of Phalaris arundinacea L., Elymus elongatus subsp. ponticus cv. Szarvasi-1 andMiscanthus × giganteus were also chosen for this experiment. Based on the collected data, a risk of erosion provoked by the above-mentioned crops has been determined by using USLE method. The crop stands and the soil have been analysed too. This analysis has focused on the organic matter evaluation, by using a brand new method. Last but not least, occurrence of Carabidae beetles has been studied and evaluated within the research; they are considered bio indicators of the environmental conditions. Our experiment has shown that Zea mays L. is the most high-yielding species. On the other hand, Phalaris arundinacea L. has not produced positive results; the most high-yielding variation of it only made a half yield of Zea mays L. In contrast to Zea mays L., grass species of Phalaris arundinacea L. andElymus elongatus have had an extraordinary anti-erosion capacity. Studying the amount of primary organic matter in the soil, we have found almost double amount of it in Miscanthus × giganteus andZea mays L. crop stands, compared to another two species. Monitoring oxidation reaction kinetics of the primary organic matter, we could count the oxidation speed constant of k. There have been dramatic differences between the individual soil samples. However, the data file is too complicated to draw the general conclusion from. On the other hand, evaluating the data gathered by studying Carabidae beetles and the environmental values of the crops stands, we have found out the crop stands are not too valuable from the environmental point of view. We have found out the perennial species have got an extraordinary anti-erosion capacity. We recommend Miscanthus × giganteus and Elymus elongatus, in particular, as an alternative to corn, especially to regions highly endangered by erosion.
