Beyond sectarianism: the dynamics of memory in Northern Irish muralism
Rava, Gabriella ; Řehořová, Irena (advisor) ; Asavei, Maria Alina (referee) ; Kocián, Jiří (referee)
Gabriella Rava- Doctoral Thesis Beyond Sectarianism: the Dynamics of Memory in Northern Irish Muralism Abstract: The present research aims to analyze the famous political murals of Northern Ireland within a renewed frame that moves beyond the theoretical dimension that has dominated the study of mural painting in the province. Proposing the concept of 'muralism', which allows for the adoption of a systematic and unitary perspective on this well-rooted practice, this work investigates its contemporary development through the analysis of some functions/trends underlying it. These are identified as: commodification and heritagization, transnationalism, commemoration, archival impulse and the related digitization and archiving of images of murals. These functions/trends, which encompass muralism both within the realm of material culture and digital practices, fall within a theoretical model that describes muralism as a dynamic system through which the communities of Northern Ireland have embodied and transmitted their own collective memories, especially those of the conflict. It is within this model, which highlights the dynamic nature and (auto)poietic character of muralism as a system of memory, that the aforementioned functions/trends are examined, moving on multiple levels of manifestation. These include...

Construction of educational model "Ball on Stick"
Coufal, Ondřej ; Formánek, Martin (referee) ; Dobossy, Barnabás (advisor)
The goal of this thesis was to create an educational model, which could be used as a demonstration of dynamic model and its regulation for future students of mechatronics. The construction was inspired by a similar construction but with much smaller dimensions where most of components were printed by a 3D printer. Afterwards there was created an electrical scheme and implemented on a printed circuit board. For the whole system was designed a caskade regulation, that makes sure the ball will reach the desired position, which is adjustable.

Universal and fully analog oscillator with transconductance amplifiers
Kus, Václav ; Zaplatílek, Karel (referee) ; Hruboš, Zdeněk (advisor)
The aim of this thesis is to design a universal analog oscillator using transconductance amplifiers. For studying behaviour of chaotic dynamical systems can be used systems Class C. Suitable way for the purpose modeling dynamic phenomena arising in these systems is an electronic circuit that exhibits the same behavior as modeled system. After familiarization with the basic principles of synthesis of integrators systems, and studying the involvement of frequently used functional blocks were designed the concept of universal chaotic oscillator using transconductance amplifiers. The functionality of this circuit has been verified by PSpice simulation program. A typical feature of chaotic oscillator is extremely sensitivity to initial conditions. Each small change on the initial parameters can lead to major change in the shape of the attractor. The result of this thesis is a functional sample of a universal chaotic oscillator, which was verified by the dynamic behavior of the given differential equations.

Vibration energy harvester as a tuned mass damper
Novák, David ; Machů, Zdeněk (referee) ; Rubeš, Ondřej (advisor)
This bachelor thesis it's about vibration energy harvester as a tuned mass damper the design of a vibration generator as a dynamic vibration damper.The work contains a research part, which examines the methods of damping mechanical systems and the influence of the vibrating generator on the vibrating base. Based on this knowledge, equations of motion were derived for the design of the model in the SIMULINK program, where we optimized the parameters for maximizing the obtained electrical power and maximizing the damping effect.

Equivalent circuit realizations of the simple chaotic oscillators
Kobza, Jaromír ; Dostál, Tomáš (referee) ; Petržela, Jiří (advisor)
The aim of this paper is to introduce with basic theory the problems encountered when considering the circuit implementation of autonomous RC chaotic oscillator with nonlinearity. All oscillator prototypes are based on one type of universal oscillator circuit. This circuit is able to generate a lot of attractors on condition of different entrance parameters. The design is based on a mathematical simulation, which includes the generation of electronic circuit values. The work is focused the transformation of these values to operational circuit configuration and simulation in a circuit simulator. The final task is to acquire chaotic attractors. Oscilloscope and spectrum analyser photos will verify the operation.

Design and realization of a new laboratory exercise with PLC B&R Automation
Cejpek, Zdeněk ; Němec, Zdeněk (referee) ; Lang, Stanislav (advisor)
This bachelor thesis is concerned with designing of a laboratory task primary dedicated for the course „Advanced control methods“, which for the education uses the instruments of company B&R Automation. From possible aproaches chooses modeling of dynamic systems using analog electrical circuits. Those circuits are realized in modular manner, in order to allow building models of various systems. The thesis also includes a desing of proper casing, which simplifies the manipulation by building of the systems. Using designed prototype modules, a model of a separately excited DC motor was built. This model is used for realization of the laboratory task, for which is provided a short manual including some basic program for Automation Studio. The thesis also briefly introduces the company B&R, it´s products and a PLC configuration used in courses „Advanced control methods“.
