Assembling and Functional Verification of a Home 3D Printer
Tesař, Jaroslav ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
This thesis was created as a bachelor project in the Faculty of Mechanical Engineering at VUT in Brno. In the theoretical part, the additive technology Rapid Prototyping is introduced together with the most common methods, followed by the assessment of advantages and disadvantages of the new technology and its possible uses in various fields of human activity. In the experimental part of the diploma thesis was assembled and the printing parameters were set. Consequently the comparison models were printed on the 3D home printer and on professional printer Dimension uPrint. The accuracy of the printers is compared. The thesis concludes with the analysis of technical and economical parameters.

Application of modern methods for production of mobile phone storage stand
Tesař, Jaroslav ; Nejedlý, Jindřich (referee) ; Sedlák, Josef (advisor)
The thesis was made as a bachelor’s project on Faculty of Mechanical Engineering, Brno University of Technology. In the theoretical part methods of Reverse Engineering were described. The principle of the following technology, the Rapid Prototyping, was also explained and the summary of advantages and disadvantages and use in technical practice for the most important methods was made. In the experimental part of the thesis the modern methods were applied for manufacturing a cell phone holder. By this the possibility of these technologies to work with complexly shaped models was verified. The casting to a silicon form was used as the alternative method of manufacturing. The summary of possibilities of manufacturing with these technologies and technical and economical evaluation were made in the end of the thesis.

uP Signal Generator
Tesař, Jaroslav ; Bradáč, Zdeněk (referee) ; Kučera, Pavel (advisor)
In the first part of this work, the digital-to-analog conversion problem and the single-chip microcontroller problem are theoretically described. The HW design of the low-frequency harmonic waveform generator, which is controlled by a microcontroller, is described in the second part. The third part deals with the description of ways how to generate harmonic waveforms using a microcontroller and DA converters. Furthermore, it describes the firmware of the microcontroller. The fourth part presents achieved results and electrical characteristics of the designed generator.

Small sacral monuments in the countryside of Moravian Budejovice
TESAŘ, Jaroslav
This bachelor´s thesis comprehensively analyzes small religious buildings in the countryside, including the important sub-analyzes, which are aimed at the protection zones in the countryside, in the administrative area, ?ORP? (municipality with extended powers) of Moravian Budejovice. Small sacral monuments are focused and photographed on the 31/12/2014. Regarding the monuments that the territory is located in, their number, status or location were not known before. The main aim of this qualification work is a complex and clear demonstration of problems of small religious monuments in the area around Moravian Budejovice. The author of the thesis describes the state of these monuments today, and determines whether they still exist on the same place they should originally be. The author mentions damaged monuments and points to the possibility of their salvation. The introductory part describes theoretical and methodological procedures that were used in creating the work and challenging terrain survey. In the final part there are results for each municipality written in tables with observed attributes and the text contains important information specifying the current state of small religious buildings in each municipality. The work includes a base map, analytical charts and tables. All objects in a given area were focused and photographed, not only for purposes of the Department of Construction and Territorial Planning, but also for the Conservation Department that required to take a photograph of each building, and if possible, from multiple perspectives.

Analýza přirozené obnovy modřínu opadavého v oblasti centrálních Brd
Tesař, Jaroslav
The aim of the thesis was to evaluate the state and conditions of the initial phase of the natural regeneration of the European larch. There were nine forest stand groups of 0.06 -- 0.2 ha (small regeneration components) on three sites (FTG 5P, 5K 5N). The density of the growths, height, height gain, age, and damage were measured in the field. Using hemispheric "Fisheye" photography, four photic parameters were observed: openness, direct site factor, indirect s.f. a total s.f. According to the analysis, European larch naturally regenerates on the selected sites successfully. The natural regeneration grows out successfully and shows high density even on sites with low light conditions, while the insolation demands, mainly on the indirect insolation, are gradually increasing at the age of 2--4 years. On the opposite, high level of insolation can have negative influence on the density and further grow out of the natural regeneration on exposed or acidic sites with possible short -- term drought.
