Enhancement of degraded speech by removing dissonant components
Sadil, Jiří ; Míča, Ivan (referee) ; Smékal, Zdeněk (advisor)
This work deals with the method of partial removal of interference from the speech signal, thereby improving the overall quality of depreciated speech signal and improve signal-to-noise ratio. Specifically, the elimination of frequent disturbance, such as crosstalk from other interviews, noise, car noise, computer fans wind coming to the microphone and general noise. The method described below is based on frequency filtering, which can be thought of as the discordant tones of intervals. The size range of discordant phenomena, be applied to the basic tone of speech, which can be thought of as a tone tempered tuning C, and thus a spectrum of dissonant speech appear as notes F #, B, and C #. The aim of my work is finding its own working methods and technical solutions for realization of removing the greatest proportion of interfering components in the signal deteriorated by filtration discordant elements.

Occupation as a prerequisite for local politics
Sadil, Jan ; Hájek, Lukáš (advisor) ; Jágr, David (referee)
In ideal case during elections, we are deciding based on our knowledge of political subjects, their candidates and quality of proposed solutions. But what happens when voters seem to have no information? Based on what are they deciding? In this bachelor thesis I'm focusing on Concept of representation by Hanna Pitkin and her takes on descriptive characteristics of candidates, to be more specific occupation of candidates and its relation to uninformed voters. In this thesis I'm using quantitative methods to find the answers.

Digital safety competences of students of teaching
SADIL, Jakub
For research and mapping of rules and standarts in IT security and summary od theoretical part of this work, I will use publications which are covering different part sof IT security and i will also consult a experts in this field. For mapping current status among the students, will be used a wide questionary survey, which will not be conducted electronicly, but will be distributed personally, to ensure that collected datas are relavant and gathered from trustworthy sources. Centerpoint of my research will be attitude of students towards those rules, and their abidance of those rules and also the ability, to pass those knowledge on the other peoples and especially to other students. The theoretical part of my work, will serve as background for more collected datas and to confront results of questionary survey and better understanding of possible consequences resulting from ignoring or obeying those rules by students of pedagogical sciences. My work will be focused on area of IT security, which are graduates most possible to encounter, during thein work. Furthermore, i will focus on practical impacts of familiarity or ignorance of those rules and baselines which are described above, in the theoretical part, or mentioned in the questionary, on the ability to carry out pedagogical related occupations. Certain part of my work will be dedicated to social networks, its usage, possible and impacts the they can have on teacher, hist ability to pass knowlidge, his autority among the students and quality of education process. From collected and summarized datas will be uncovered current status of IT security awareness and will be created work, that could be used to improve the metodology, and content of information technology studies on universities and high schools, mostly on gymnaziums.
