BRDF workshop
Matějka, Jiří ; Pelikán, Josef (advisor) ; Karlík, Ondřej (referee)
This thesis develops an application for interactive experiments with BRDF functions. Arbitrary BRDF function may be specified with an analytic formula, including arbitrary number of parameters. A simple scene is displayed, using specified BRDF. The parameters can be modified which has an immediate impact to the scene's appearance. The application can utilize a programmable GPU for high speed of rendering.

Lighting workshop
Matějka, Jiří ; Horáček, Jan (referee) ; Pelikán, Josef (advisor)
The object of this work is to design and implement an application for interactive experiments with local illumination models. The user can arbitrarily define an illumination model with mathematical formulas and mark certain parameters to be changeable. While such parameters are changed, the program smoothly draws an updated 3D scene. The scene can be defined in the text format, while several scenes are bundled with the program. Two predefined well-known illumination models are also bundled with the program - Strauss' and Phong's model.

Technologie pěstování a možnosti využití druhu Scorzonera hispanica L.
Matějka, Jiří
The Diploma work based upon a topic Technology of growing and possibilities of usage of species Scorzonera hispanica L. presents and evaluates in its literary part still known information about possibilities of growing, content substances and possibilities of usage of Scorzonera hispanica L.. The practical part of the work describes an experiment, which was created in 2014 in property in region of Bohemia Moravian Highlands. The experiment consisted of making two different agrotechnical methods of growing and two harvests and following comparison from perspective of crop and nutritional value. On the foundations of the statistical evaluation, an influence of chosen agrotechnical method of growing on crop, content of solids, sodium and magnesium was proved. The date of the harvest influenced content of sodium, calcium and magnesium. Possibilities of use of Scorzonera hispanica L. were checked by degustation and marketing research, when interest in these species of root vegetable was proved.

Side channel attacks on chip cards
Matějka, Jiří ; Morský, Ondřej (referee) ; Martinásek, Zdeněk (advisor)
This master thesis deals about the issues of chip cards’ side channels. Side channels are new method in cryptanalysis. Unlike classical cryptanalysis, which looks for weaknesses of mathematical structure of algorithms, side channel’s analysis use weaknesses of physical implementation of these algorithms. First part describes chip cards, their usage a security. There is mentioned the issue of cryptographic algorithms and their implementation on smart cards. There are described well-known side channels and examples of their abuse. Practical part of this thesis is focused on a proposal of a laboratory task, which demonstrates power-based side channel attack on smart card. There is designed laboratory workplace for this task, software for measurement and analysis is implemented in development tool LabVIEW. In the last part is this attack realized, the target of this attack is a standard SIM card.
