Simple text-independent voice lock - speaker verification software system
Kotulek, Milan ; Dolenský,, Jan (referee) ; Staněk, Miroslav (advisor)
A brief introduction into biometrics is described in this thesis leading to description and to design a solution of verification system using speech analysis. The designed system provides firstly basic signal processing, then vowel recognition in fluent Czech speech. For each found vowel, observed speech features are calculated. The created GUI application was tested on created speaker database and its efficiency is approximately 54 % for short testing utterances, and approx. 88 % for long testing utterances respectively.

Altitmeter for RC aircraft models
Kotulek, Milan ; Štohanzl, Milan (referee) ; Prokopec, Jan (advisor)
Bachelor thesis describes a device for measuring and recording flight position RC model, which consist of a microcontroller and a pressure sensor. It measures values of atmosferic pressure and these data are convert by microcontroller to specific height. All is during flight saved to memory and later can be transferred to PC.
