Averaging of biological signals
Kubík, Adam ; Čmiel, Vratislav (referee) ; Smital, Lukáš (advisor)
The main aim of this thesis is to introduce issue of averaging of biological signals. The first part of the thesis deals with the principles of individual averaging methods (constant, floating and exponential window) and describes their basic features. Moreover, the principle of filtered residue, detection of QRS complex, and stretching/shrinking the length of RR-interval to the standardized length are explicated. In the second part of the thesis the outcomes of practically realized (Matlab and GUI) methods of averaging (by final signal-to-noise ratio) are evaluated. Signals from MIT-BIH database are used.

Searching repetitive DNA in nucleotide sequences
Moskovská, Kateřina ; Provazník, Ivo (referee) ; Kubicová, Vladimíra (advisor)
This bachelor thesis deals with problem of repetitive DNA and algorithms for searching tandem repeats. Tandem repeats are important for biological industry. They are used as gene marker for creating genetic maps, profiles of DNA for paternity testing and in forensic sphere. Tandem repeats wreak several sever humen illness and it is another reason for their searching. Therefore are algorithms for searching of tandem repeats objects of many studies. We can divided algorithms to two main groups – algorithms based on string matching and algorithms based on digital signal processing. Task of this bachelor thesis is choose one member of each group and propose their implementation and than implement them in program Matlab. Result of this thesis should be comparison both programs. This comparison pass off on the basis of chosen criterion and several sequences. Both program transform these sequences and than can be programs compare.
