Methods for quadrature modulator imbalance compensation
Povalač, Karel ; Valenta, Václav (referee) ; Maršálek, Roman (advisor)
Quadrature modulator (demodulator) is used in transmitting (receiving) part of many devices. Unwanted imbalance can influence amplitude, phase or DC offset of modulator (demodulator). Correction of imbalance was a main subject of thesis. Simulations of these methods were created in MATLAB and results were compared. Basics of methods were implement on programmable logic field by program Xilinx ISE. Development kit V2MB1000 with analogue board Memec P160 was chosen for this purpose. In the last part were compare simulation results with practical measurement.

The most frequent disease of German boxer
Augstenová, Jennifer ; Rozinek, Jiří (advisor) ; Karlasová, Barbora (referee)
This bachelor thesis deals with the most frequent disease of German boxer. The history and description of the boxer breed is shortly described at the beginning. German boxer is very popular type of dog. It is a breed that has been originally used for hunting and fight with wild animals. Later was boxer trained as a police dog. Now it is mostly kept as family companion due to its great personality.
In next part of the thesis, every new chapter begins with anatomy of organ where disease occurs. Then there are described the most frequent diseases of German boxer based on consultations with veterinary and scientific literature. Sympthoms, prevalence, diagnosis and potential treatment are described, mostly with pictures.
Spondylosis deformans which affects German boxer the most, must have X-ray examination. Dilated cardiomyopathy and arrhythmogenic cardiomyopathy of the right ventricle are responsible for the most bereavement of dogs of all the described diseases.
