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.

Methods for the determination of radiological impact of the food chains
Tesař, Jakub ; Bartusková,, Miluše (referee) ; Havránková, Barbora (advisor)
The diploma work presents comprehensive overview of methods of determination of radiological impact on food chains. It describes the determination of radionuclides in groceries in common radiation situation and in unusual radiation situation. Practical part of the work presents two model radiation events. These are radiation event in the territory of Czech Republic and radiation event in the territory of other country and its impact on Czech Republic. In the end both model situations are compared.

Secondary materials from household waste and their position in the global market
Tesař, Jan ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
The barchelor thesis is focused on the issues of material recovery of municipal waste. The work presents the basic concepts of waste management and resource data to help analyze the current virtual situation in the field of waste management. Work specifies the components with the greatest potential for material recovery. For the selected folder, which can be commonly referred to secondary raw materials, work tries to describe the flow of materials and meet with their potential application in the market.

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.

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.

The Occult Photography
Tesař, Jan ; Dvořák, Tomáš (advisor) ; Musilová, Helena (referee)
The title of this diploma work is "The occult photography". Main aim of this essay is to get closer to the phenomenon of spiritualism in photography. The work treats of concrete pictures and their authors. The introduction is followed by chapter "Conception of ?reality? in the occult photoraphy". It contains e.g. information about perception of this topic by various theoreticians. The second chapter "The world´s occult photography" consists to three parts. The first of them - "Materialization of human being´s spirits", considers origins of spiritualism (for example work of William Mumler). The second part - "Levitation of insentient subjects", discusses works of Frederick Hudson and Edouard Isidor Buguet. The third part - "The unidentifiable phenomenons", treats of concrete examples of such phenomenons and about Kirlian´s photography. The last chapter is called "The Czech occult photography". The conclusion is a kind of contemplation about perception of the occult photography in present and in past, about differences between this perception in our country and abroad, and also confrontation with other kinds of visuality.
