State trajectory approach to the interpretation of self-organization in the Belousov-Zhabotinsky reaction
ZHYROVA, Anna
The Belousov-Zhabotinsky reaction is a well-known model for investigating the self-organization manifestations in nature. The chemical reaction cascade is easy to control and measure in laboratory conditions, which makes the investigation of diverse scenarios of the system behavior possible. The aim of this thesis was to evaluate the course of the reaction under the assumption of multifractality of observed chemical patterns. The approach of the information entropy theory was applied to image analysis to assess the visible changes in the reaction oscillation. Furthermore, the new characteristics - point information gain entropy and point information gain entropy density - were also introduced. These values were used to construct the state trajectory of the complex system with unique oscillation states recognition by multivariate stochastic data analysis. The reliability of the developed approach was tested on numerous experiments, including the insufficiently-studied BZ reaction wave formation under the space constriction and distortion by re-shaking effect. It has been confirmed that each of the system states has its own characteristic spectrum of information entropy. The obtained state-trajectories for the BZ reaction allows researchers to study the changing system behavior in response to variation of the initial conditions and to make a prediction about state-trajectory evolution in the imminent future. It was showed that the information entropy calculation is an effective and cheap tool for non-invasive analysis of a wide range of self-organized systems. Finally, it may be implemented also to automate laborious tasks for different cell stage recognition in medicine and biology.

Analysis of enterprise's complex system
Malackanič, Roman ; Sigmund, Tomáš (advisor) ; Berta, Michal (referee)
This diploma thesis focuses on the analysis of a particular soft complex system in the company. This system is a running car service with a determined problem situation. This system and its problem is then evaluated in terms of soft systems methodology, system dynamics and critical systems heuristics. The theoretical section provides concepts to understand the complexity and also individual system approaches. As beneficial of work I consider the practical part, which is aimed to the analysis of complex real-world system using the selected approaches as well as an evaluation of these approaches. Main purpose is to bring comparisons and suggestions for improvement and also a broader view to the system. All of this increases information value of approaches and we are able to deliver more relevant information. Thesis is therefore focused not only to deal with examples from practice but also to extend the selected theories within the system approaches.
The interactivity of ICT tools
KORTAN, Michal
This bachelor thesis deals with the concept of interactivity which, in course of time, became overused, not only in terms of information systems. Thus, the thesis also discusses the unclear interpretation of interactivity and aims to express more apt definition. The interactivity is analyzed across various fields, which further provides a basis for the establishment of unbiased model called classification frame defining a degree of interactivity of specified complex systems.
