Plagiarism detection of text documents
Lízal, Radek ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
This diploma thesis introduces the definition of plagiarism, distinguishes the types of plagiaries which often take place in praxis and the ways of determining the suspected texts. The means of detection are essential; therefore a whole chapter is dedicated to those. For the detection purposes, it is vital to pre-process the data to reduce the demand factor of the program. There is a preview of some programs which are already being used for the detection of plagiarism. The following chapter introduces some selected indications which have been implemented in the Matlab environment to create a detector of plagiaries in text documents. The created program is described in chapter eight. The applied indications and the detector response are described in a chapter called Indications testing. The testing proved the quality of these indications. The results together with pros and cons of the particular methods are discussed in the conclusion.

Recognizing and analyzing of move intention in EEG signal
Lízal, Radek ; Kolářová, Jana (referee) ; Bubník, Karel (advisor)
This thesis contains information about the electroencephalograph and its characteristics, taking into account the possible measurements and ways of reading them. The factors which might influence the quality of the signal are taken into consideration as well. Furthermore, the methods of processing the electroencephalography signal are analysed, followed by theoretical description of brain reactions preceding both realised and intended movement. Moreover, two different measurement experiments are described and the obtained results are commented on and compared to the theoretical findings.

Recognizing and analyzing of move intention in EEG signal
Lízal, Radek ; Kozumplík, Jiří (referee) ; Bubník, Karel (advisor)
This thesis deals in its first part with information about typical features of an electroencephalograph, the records of the actions it can measure and the ways of dealing with the results. Possible factors of influence on the signal are described. The second part depicts the methods of processing the signal, in order to obtain useful information. The following part describes in detail the actual experiment. Displayed are the results of the experiment, as well as a thorough explanation of the characteristics of these results.
