Software module generating "atoms" for purposes of overcomplete signal representation
Špiřík, Jan ; Průša, Zdeněk (referee) ; Rajmic, Pavel (advisor)
The aim of this master thesis is generating new "atoms'' for purposes of overcomplete signal representation for toolbox Frames in MATLAB. At first is described the principle of overcomplete systems and so-called frames. In the thesis is introduced the basic distribution of frames and conditions of their constructions. There is described the basic principle of finding the sparse solutions in overcomplete systems too. The main part is dealt with construction single functions for generating "atoms'', such as: Gabor function, B-splines, Bézier curves, Daubechies wavelets, etc. At last there is introduced an example of usage these functions for reconstruction signal in comparison with Fourier and wavelet transforms.

On the digitizing and modeling of real surfaces for machining
Šnejdar, Martin ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
This bachelor thesis deals with the procedures of the digitizing and modeling of real surfaces for machining. The work includes technological procedures and individual phases of the process leading to acquisition of resultant surface. The aim of this work is familiar with the procedures and phases in reverse engineering, which is demonstrated on a particular example using the Mathematica software.
