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.

Demonstration of State Space Search Methods
Tureček, Martin ; Drozdová, Martina (referee) ; Zbořil, František (advisor)
This bachelor's thesis describes the issue of state space search methods. Thesis was focused namely on the practical part. Its main goal was to create a demonstration application which should serve as an additional help for Fundamentals of Artificial Intelligence course. The resulting application satisfies this requirement thanks to an easy control, a possibility of steping through the alghoritm and an attractive graphic layout. The application is also implemented as a java applet, so its start should be possible from anywhere.

Models of Dynamics and Responses of Multi-body Systems
Kšica, Filip ; Houfek, Lubomír (referee) ; Hadaš, Zdeněk (advisor)
The aim of this diploma thesis is to evaluate the potential of available methods for simplification and reduction of complex models of technical systems and their integration with experimental models. Finding methods, which would allow us to create models and run simulations in shorter periods of time, is key in design process of modern technical systems. In the beginning of this thesis, a theory necessary for understanding and application of presented methods is given. These methods can be separated into two groups, first as experiment related, second as simulation related. The first group contains methods for experimental evaluation of response and its use for dynamic system identification. The second group contains methods of finite element model creation, with the usage of standard structural elements as well as Component Mode Synthesis substructures, and these models are in the following step reduced into state space models. In the next step, all presented methods are applied on simple experimental structure. In conclusion, the results of simulations are the subject for comparison not only from quantitative point of view, but also, for the purpose of practical application, in terms of time, feasibility, versatility and accuracy. The system identification method along with state space method proved to be very suitable. The results presented in this thesis might help, by selecting the appropriate method, in simpler evaluation of dynamic properties of technical structures.

Determining the size of the state space
Rybanský, Marian ; Krček, Petr (referee) ; Roupec, Jan (advisor)
Objective of the thesis is to describe and evaluate the appropriate methods to determine the size of the state space. State space will be created by using a program (generator) which generates a state space, from the input values and regulations (model). To objectively assess the state space we classifies according to their parameters. Classified state space will be added to a class, in which the demarcation perform evaluation methods will be done.

Use of a simulation model for the development of an automatic algorithm for creating a routing table and path evaluation in a conveyor system
Weyrová, Dominika ; Simeonov, Simeon (referee) ; Hromková, Ivana (advisor)
The diploma thesis deals with the use of a simulation model for the development of an automatic algorithm for the creation of a routing table and route evaluation in a transport system. It includes a search of modeling and simulation issues and state-space search issues with an analysis of available search methods. The simulation model of the transport system is created in the software Tecnomatix Plant Simulation, where an algorithm for automatic creation of routing tables for routing and evaluation of routes according to static criteria is subsequently developed and tested. The work presents a proposal for the principle of the algorithm for evaluating the routes of the transport system, including dynamic criteria and their optimization.

Ball & Plate Model: simulation and control design
Burlachenko, Sofiia ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
This thesis deals with the identification and regulation of the "Ball & Plate" model. The thesis contains a description of the existing real model and the relevant mathematical and simulation model. The root hodograph method and the state space method are used to calculate the controller, especially the feedback controller with integrator. The final part of the work is devoted to the 3D model construction using Simulink and SimScape, which describes and visualizes the behavior of the real model and enables simulation experiments to be performed quickly and easily.

Comparison of Programs for Scheduling
Kubalcová, Monika ; Martinek, David (referee) ; Křena, Bohuslav (advisor)
This thesis deals with timetabling issues at the Faculty of Information Technology, Brno University of Technology. It focuses mainly on scheduling of lectures and exams for students. In first part, the current situation, restrictive conditions and actual procedure are described. Afterwards, theoretical aspects of scheduling problem are discussed. In the second part of the thesis, selected software application for automatic generation of timetables are compared. The most suitable application is then evaluated by producing a real timetable. The achieved results are discussed and the future directions are suggested in the conclusion.
