The master‘s thesis deals with utilization of infrared camera for temperature measurement of electrical machines. The first part describes non-contact temperature measuring, the second part describes principle of sensors that evaluate quantity of incident infrared radiation. In the next part there is termovision camera SAT-HY 6800 presented and the instructional manual for SAT Report computer programme created. This computer programme is used for analyzing of termovision pictures from the SAT-HY 6800 termovison camera. The chapter 7 describes temperature measuring of one-phase asynchronous motor type J22TO484. The chapter 8 describes temperature measuring of semiconductor components of EC motor G6 series. Both of these motors are produced by ATAS elektromotory Náchod a.s. The last part of the thesis describes creation of animation of one-phase asynchronous motor type J22TO455. The animation was created in 3ds Max computer programme.

This thesis deals with the method of distributed ray tracing focusing on optimalization of this method. The method uses simulation of some attributes of light by distributing rays of lights and it produces high quality and partly realistic images. The price for realitic effects is the high computational complexity of the method. The thesis analysis the theory connected with these aspects. A large part describes optimalizations of this method, i.e. searching for the nearest triangle intersection using kd-trees, quasi random sampling with faster convergence, the use of SSE instruction set and fast ray - triangle intersection. These optimalizations brought a noticable speed - up. The thesis includes description of implementation of these techniques. The implementation itself emphasises the practical usability including generating some advanced animations and universal description of objects.

The field of this project is size restricted graphic intro. The paper deals with motivation creating such an intro and talks briefly about history. Main focus is put on general description of various principles common in demo development, techiques used achieving the practical assignment are provided with more detailed description.

Following work deals with subject matter of digital modelling and animation of biological structures. Software tools for computer generated images (CGI), well proven in common practice, are evaluated, as well as tools for specific activities, available inside chosen software environment. Among vast pool of modelling approaches are discussed tools suitable for creation and representation of selected structures, along with tools essential for their consequent animation. Possible rendering approaches and their parameters in relation to qualities of resulting computer-generated images are discussed as well. Above-mentioned approaches will be consequently utilized for modelling, physical simulation and animation of erythrocyte’s flow throughout blood vessel in following project. Resulting output of that work will be based on series of digital images, suitable for creating video-sequence containing abovementioned animation in end-user digestible form.

The presented work deals with social-pedagogy approaches in the issue-based youth work centres. The first part attends to the analysis of the idea {\clqq}unattached youth``. It takes aspect of the lifestyle sociology, the social education and the developmental psychology. The viewed group of the unattached youth is presented as a group of the adolescents; they have problems with the coping strategies in the post-modern society. The second part of the work takes their problems as a starting-point for the next reflec-tion. It determines criteria of the effective youth work dealing with the unattached youth. Finally the third applied part evaluates the four current types of the issue-based youth work: the German open youth work (Offene Kinder- und Jugendarbeit), the British youth work, the Czech issue-based youth work centres and the Czech open youth centres. The evaluation is focused on the criteria of the effective youth work dealing with the unat-tached youth; we derived in the second part. Overall the main aim of this work is to point out the effective issue-based youth work has to take into account the social and developmental needs of the target group.
