Fourier transformation for exon prediction
Rusina, Michal ; Škutková, Helena (referee) ; Maděránková, Denisa (advisor)
In this bachelor thesis there are described the methods of the prediction of exon. The first part is aimed at the difference between the prokaryotic and eukaryotic organisms, the description of the DNA structure and the explanation of the terms exon and intron. The second section of the theoretic part includes four methods of the prediction of exons namely dynamic programming, neural networks, hidden Markov models and discrete Fourier transform. In the practical part there was created the program called Predikce_exonu that searches exons in nucleotide sequences and works on the principle of the Fourier transform. This algorithm together with 3 freely available programs was tested on 25 sequences and the success of their prediction was described by sensitivity and specificity.

Properties of ultrasound probes
Rusina, Michal ; Mézl, Martin (referee) ; Harabiš, Vratislav (advisor)
This master thesis deals with the measurement properties of ultrasound probes. Ultrasound probes and their parameters significantly affect the quality of the final image. Values of pa-rameters of the probes may change due to their use, because probes may be damaged and the final image may no longer be correct. For these reasons the measurements of parameters of probes are very important. In this master thesis there are described and implemented the possibility of measuring the spatial resolution, focal zone, the sensitivity of the probe and measuring the length of the dead zone. Two ultrasonic phantoms were used for measuring. In the practical part there was created the program called Mereni_parametru, which allows to determine the value of four parameters from captured images of the phantom. Further, there are listed and described measured values for five ultrasonic probes. Results for two of these probes are then compared with the parameters given by the manufacturers.
