Electrical Activity Brain Mapping
Dobeš, Petr ; Drahanský, Martin (referee) ; Kupková, Karolína (advisor)
Electrical activity of human brain is one of the most significant signals of biological origin. In order to understand and interpret electroencephalogram (EEG signal) correctly, it is often necessary to perform its visualization. This bachelor thesis deals with EEG signal and its visualization using topographic mapping. The work includes the basics of theory and processing of EEG signal. Moreover, this work consists of design proposal and implementation of an application for topographic mapping of EEG signal obtained using Emotiv Epoc Headset device. Visualization is performed in real time (at the time of measurement). Visualized quantities are amplitude and frequency domain with the possibility to select frequency bands. Implemented application represents an alternative to the procedure when EEG signal has to be recorded and stored in order to perform its visualization.

Spectral Analysis of EEG Signal
Miklenda, Petr ; Orság, Filip (referee) ; Kupková, Karolína (advisor)
This bachelor thesis is focused at the EEG signal analysis using the Fast Fourier Transform. The theoretical part consist of EEG signal description, its creation and selected method for signal analysis. The practical part presents program for recording data from EEG headset and displaying the Fourier spectrum.

Bioinformatics of human genome
Kupková, Karolína ; Provazník, Ivo (referee) ; Maděránková, Denisa (advisor)
Bachelor thesis deals with DNA segments containing only adenine and guanine. The theoretical part describes the structure and composition of deoxyribonucleic acid, chromosomes and genes. There are basic informations about chimpanzees and the human genome and conformations of the chains containing adenine with guanine. The practical part consists of a program that searches for the required sections in sequence, it displays and saves it. The thesis includes analysis of genes which are common for humans and chimpanzees, which were analyzed to determine randomness, functionality a preserving of these sections.

Model of dynamic contrast CT data for verification of registration algorithms
Kupková, Karolína ; Harabiš, Vratislav (referee) ; Walek, Petr (advisor)
This work is focused on the description of the dynamic contrast-enhanced CT examination and its contribution in the pneumooncology. It includes a program for creating a two-dimensional model of the scan from the thorax and for the perfuse examination simulation using the time-density curve. Real CT data are simulated more authentic using rigid geometric transformations and noise. The model will be used for the validation of registration algorithms that is used to suppress the spatial deformation generated by patient motions during the long time examination.
