Quaternion algebras
Bečka, Pavel ; Klaška, Jiří (referee) ; Kureš, Miroslav (advisor)
This thesis deals with quaternion algebras. A quaternion algebra is a four dimensional vector space with basis 1, i, j, k and multiplication defined as i2 = a, j2 = b, ij = -ji = k. The thesis deals with the basic attributes of quaternion algebras, quaternion orders and maximal orders. Lastly the thesis deals with the concept of discriminant of algebras and connected terms like Hilbert symbol and Legendre symbol. Throughout the thesis we show solved problems using mathematical software SAGE.
Applications of wavelet transform in Mathematica and Sage
Novotný, Radek ; Trzos, Michal (referee) ; Rajmic, Pavel (advisor)
This thesis focuses on image processing using wavelet transform. The usage of wavelet transform is analysed especially for image compression and image noise reduction purposes. The analysis describes in detail aspects and application of the following wavelet transform methods: CWT, DWT, DTWT, 2D DWT. The thesis further explains the meaning of the mother wavelet and studies certain specific kinds of wavelets, kinds of thresholding and its purposes and also touches on the JPEG2000 standard. Mathematica and Sage software packages were used to design algorithms for image compression and image noise reduction, utilising relevant wavelet transform findings. The concluding part of the thesis compares the two software packages and results obtained using different algorithms.

How to motivate primary school children to think and act in an environmental way
CHLOUPKOVÁ, Magda
The contents of the Thesis feature a survey of contemporary international attitude to environmental development and its effect on the educational trends in the Czech republic. Also, the short-term eco-educational project intended for primary school children is included here in the Thesis. The aim of the project is to arouse environmental awareness of children and excite their interest in this matter, which is considered to be the first essential step towards the sustainable development.
