Class D audio amplifier for laboratory measurements
Svorad, Adam ; Petržela, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
Bachelor’s thesis delves into a field of Class-D audio amplifiers. Keystone part of the work summarizes theoretical knowledge focused on measuring techniques of lowfrequency amplifiers and audio amplifier design. A deeper insight into building blocks of a general Class-D amplifier is also presented. Gained erudition is applied in the second part, which is devoted to a construction of the device. Exceptional attention is drawn to the design of robust external driver and sophisticated output analog filter. Blueprints required for a PBC layout are provided as well as outputs of performance measurements taken of a fabricated prototype.

Increasing quality of facial images using sequence of images
Svorad, Adam ; Mezina, Anzhelika (referee) ; Burget, Radim (advisor)
Diplomova praca sa zameriava na oblast zaostrovania obrazkov tvari. V teoretickej casti prace budu prezentovane moderne metody zaostrovania obrazkov pomocou jedineho obrazku a metody editacie obrazkov. Prakticka cast sa zameria na pristupy rekonstrukcie obrazkov zo sekvencie poskodenych obrazkov. Viacere modely neuronovych sieti so vstupom pre viacero obrazkov budu zhotovene a vyhodnotene. Alternativny pristup v podobe balika nastrojov na editaciu obrazkov bude taktiez predstaveny. Tieto nastroje budu vyuzivat najmodernejsie pristupy k editacii obrazkov s cielom spojit vizualne prvky tvari zo vstupnej sekvencie obrazkov do jedneho finalneho vystupu. V zavere prace budu vsetky metody navzajom porovnane.
