The analysis of psychoacoustic perception of chords composed from different full and variously colored signals
Vejmělka, Daniel ; Musil, Jaroslav (referee) ; Jirásek, Ondřej (advisor)
This thesis is dealing with the impact of frequency spectrum of musical sounds on psycho-acoustical perception of the listener. It studies how differently filled harmonic spectrums can influence listener’s ability to determine individual notes in a chord and what influence, on recognizability of a chord, inharmonic elements have. It explores different methods of psycho-acoustic measurements and further data processing. The experiment is based on a method of paired comparisons and was realized in a form of listening test with more than 100 participants. The test is focused on typical representatives of different groups of musical instruments. It studies the impact of different colors of sound used in different types of chords. It further deals with statistical processing of the recovered data.

Analysis of Influence of Hardness and Alteration of Piano Hammer on Strength and Spectrum of Signal
Mikulášková, Aneta ; Musil, Jaroslav (referee) ; Jirásek, Ondřej (advisor)
The bachelor’s thesis deals with the analysis of the time-varying spectrum of sound of the piano series 125 and M 110 by PETROF and the influence of intonation on this spectrum. It analyzes the higher harmonic components in relation to the force applied to strings and the use of variously tuned hammers. Bachelor’s thesis observes the effect of the dynamics of keystroke and intonation on the pitch of the tone in its time and frequency plane and tone’s energy loss in relation with the dynamics. Further, the thesis describes the way of measuring and recording the captured tone samples and their subsequent processing and analysis in the application created in MATLAB development environment.

Psychology of advertising
Musil, Jaroslav ; Michálek, Pavel (advisor)
This thesis looks into one of the most used marketing mixes of tools, commercials. The main part explores the effect of commercials directly on the end-users, on their shopping behaviour and how it effects their decisions. The first, theoretical part focuses on analyses and defining of basic parameters of a psychological commercial which is needed for implementation of the research part. The research was done with the help of the questionnaires when questions both open and closed were asked. The second part of the thesis presents the outcomes of the research, for the purpose of which were selected the aim groups like children and their parents. For higher objectivity two types of questionnaires were used, separate for children and parents. Based on the gained data it was detected that both children and parents are effected by commercials. One outcome of the questionnaires is that children do not realize the effect of the advertising, while their parents are aware of its effects on them.

High-speed rail in France within the scope of low cost railway companies
Musil, Jaroslav ; Zelený, Lubomír (advisor) ; Cveček, Jiří (referee)
The Master Thesis focuses on development of high-speed rail in France within the scope of low-cost rail companies. The theoretical part describes the process of formation and development of French railways since the beginning of 19th century. It also discusses reasons leading to the creation of high-speed rail and different rail routes and also organizational structure of the company SNCF. Within analytical part, it describes researched types of transport and different groups of passengers. In the last part of the paper, with a help of multicriterial analyses, the most suitable type of transport on a certain route for each group of passengers is chosen.
