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.
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.
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.
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.
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.
Energetic usage of grasses
KOPECKÝ, Marek
The aim of this work is verification the suitability of selected species of grass (Dactylis glomerata, Arrhenatherum elatius, Phalaris arundinacea) for different varieties of energy utilization and the evaluation of economic efficiency of their cultivation and usage. A part of this work is a literature review summarizing the issues of renewable energy, focusing on biomass and energy utilization of grass. There has been used literature of various authors in elaboration the research literature. Based on field tests, there have been developed economic models demonstrating the efficiency of cultivation of selected grass species.
