Adaptive Noise Cancellation in Speech Application
Vomáčka, Jan ; Průša, Zdeněk (referee) ; Sysel, Petr (advisor)
This semestral project deal with methods adaptive noise rejection in acoustic recordings, above all speech signals. Work deal with proposal of suitable system for effective remove noise from acoustic recordings. In theoretic parts are out of print principles of adaptive filters and method of repression noise in acoustic recordings. In practical parts come out proposal and system simulation for adaptive noise rejection in speech.

Advanced method of signal time-stretching based on tonal and non-tonal segment detection
Vomáčka, Jan ; Trzos, Michal (referee) ; Balík, Miroslav (advisor)
This thesis deals with the method for time conversion of an audio signal based on a different approach to groups tonal and non-tonal segment signal implemented in Matlab. The first part deal with methods for musical signal processing based on time compression or expansion and describes the problems associated with the current way of implementing these methods. The following describes the methods of variable segmentation and tonal and non-tonal components detection in the audio recording. At the second part are these methods of variable segmentation, tonal component detection and time compression or expansion implemented in MATLAB. At the third part is performed testing on sound recordings and evaluation of results.

Modernization of Data Storage Technology
Lexmaul, Petr ; Vomáčka, Jan (referee) ; Kříž, Jiří (advisor)
The bachelor thesis focuses on issue data storage and data backup in a specific organization. It does the task provide the reader with a comprehensive overview which information and data work in the design of a corporate network focused on data storage. It also deals with the data backup, their types and the need for backing up data in the enterprise.
