Mathematical modelling of walking robots
Kiša, Daniel ; Opluštil, Zdeněk (oponent) ; Tomášek, Petr (vedoucí práce)
This master's thesis deals with mathematical models of walking robots. Two such models are introduced. The rimless wheel, a passive precursor for other models, is studied analytically in detail. The compass gait biped model is analysed and simulated numerically in the Python programming language. A method for finding the conditions for passive gait of the biped is also implemented.

Unconventional Signals Oscillators
Hruboš, Zdeněk ; Galajda, Pavol (oponent) ; Štork, Milan (oponent) ; Petržela, Jiří (vedoucí práce)
The doctoral thesis deals with electronically adjustable oscillators suitable for signal generation, study of the nonlinear properties associated with the active elements used and, considering these, its capability to convert harmonic signal into chaotic waveform. Individual platforms for evolution of the strange attractors are discussed in detail. In the doctoral thesis, modeling of the real physical and biological systems exhibiting chaotic behavior by using analog electronic building blocks and modern functional devices (OTA, MO-OTA, CCII±, DVCC±, etc.) with experimental verification of proposed structures is presented. One part of theses deals with possibilities in the area of analog–digital synthesis of the nonlinear dynamical systems, the study of changes in the mathematical models and corresponding solutions. At the end is presented detailed analysis of the impact and influences of active elements parasitics in terms of qualitative changes in the global dynamic behavior of the individual systems and possibility of chaos destruction via parasitic properties of the used active devices.
