Automatic Harmony Generation
Bobčík, Martin ; Drahošová, Michaela (referee) ; Vašíček, Zdeněk (advisor)
Goal of this master thesis is to study harmonization based on knowledge of given melody and to design a system which will meaningfully automate this activity. In the work there is covered basics of music theory needed for this topic and previous other approaches to this problematic. There is also covered machine learning, neural networks and recurrent neural networks. In the end, there is outlined design of the system, how to make it work and how to use it. Four experiments were executed with the system. Harmonization of the short melodies were unpleasant. Harmonization of longer melodies were overall more successful though. A possible cause might be relatively small used neural network of the system.

Security Analysis of Mifare Classic Smart Cards
Bobčík, Martin ; Hellebrandt, Lukáš (referee) ; Hujňák, Ondřej (advisor)
Goal of this bachelor thesis is a security study of MIFARE Classic contactless smart cards and risk analysis of their usage. There are described individual vunerabilities in the design and CRYPTO1 cipher of such cards. In this thesis is also experimented with Chameleon Mini device, which is used to perform two attacks and one cryptoanalysis of the cards. Namely, card emulation, relay attack, and analysis of insufficient randomness of cards' pseudorandom number generator. From those, only card emulation was fully successful.
Design of doublebeam of bridge crane 8 tonne
Bobčík, Martin ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with design of doublebeam of bridge crane (8 tonne). The purpose of this thesis is to design the main parameters of the crane bridge. First of all, I chose from the catalog wire rope hoist. I proposed preliminary dimensions of mainbeam and crossbeam. I made strength check of mainbeam and crossbeam. For attachment mainbeam and crossbeam I chose fitted bolts. I calculated required number of fitted bolts M12. From the standards I chose wheels. I checked the wheels to maximum contact pressure and service life. I chose bearings from catalog SKF. I checked the bearings to service life. I proposed dimension of shafts. From the rolling resistance and friction, I calculated the power output of the engine. At the last I proposed cable trolleys and control of the crane.
