Remote Nature
Richtr, Pavel ; Suchánek, Jiří (referee) ; Krekovič, Slavomír (advisor)
In my thesis I deal with the interactivity between the weather and the virtual model, whose main output is sound. I'm trying to create generative installation where reacts virtua oraganism with real environment and generates signals that can be interpreted in a sound to explore the aesthetic relations of that connection.

Sociological Simulator
Ludwig, Petr ; Plchot, Oldřich (referee) ; Fapšo, Michal (advisor)
This thesis describes the paradigm of complex systems and discusses possibilities of their modeling and simulations. The work shows the suitability of using multi-agent modeling for creating abstraction of social environment, that is one of the major complex systems. Thesis content includes an analysis of tools that are available for creating multi-agent simulators. The core of this thesis are processed research documents and a demonstrative model of social phenomenon known as procrastination.

Nucleation in complex systems
Kulveit, Jan ; Demo, Pavel (advisor) ; Slanina, František (referee) ; Vlček, Jaroslav (referee)
Title: Nucleation in complex systems Author: Jan Kulveit Institute: Institute of Physics of the Czech Academy of Sciences Supervisor: prof. Pavel Demo, Institute of Physics of the Czech Academy ofSciences, Department of Optical Materials Abstract: We studied nucleation in progressively more abstract contexts and systems, starting from classical nucleation theory and ending with nucleation in complex networks. The cases studied include impurity nucleation in a solid matrix on several alkali halide crystals, where we determined formation energies for clusters, treated as defects, starting from single impurity-vacancy dipole and small aggregates to possible configurations of larger clusters. In the next part, we turn to the study of heterogeneous nucleation. While in the usual treatment of heterogeneous nucleation the surface energy is assumed to be homogenous, we ask the question what happens if we consider the surface energy to be heteroge- neous.Utilizing umbrella sampling computer simulations we find the nucleation barrier can be significantly lowered in the presence of surface heterogeneity, even if the average surface energy is kept constant. In the last part we study influence of clustering coefficient on phase transitions in scale-free networks, using forward flux sampling (FFS). Keywords: nucleation,...

Agent-based modelling in economics
Hanuš, Jiří ; Raab, Jan (advisor) ; Bejček, Eduard (referee)
In this thesis, we present one view on economic modelling - Agent based modelling and Agent based computational economics, which is computation- ally intensive method that simulates interactions between entities in econ- omy instead of focusing on stable equilibria. We will provide introduction into Complex systems theory, which explains many phenomena we can see in economies and explain why these phenomena make it hard for economists to design models explaining behavior of people in real world. We will show one possible model of face-to-face interactions between consumers and firms and its implementation, where we can see whether it can sustain for a period of time in dynamic but stable state. 1

Inherent instability of financial markets
Hladík, Jan ; Buben, Radek (advisor) ; Znoj, Milan (referee)
The main aim of this presented diploma thesis is to help build a systematic understanding of the political and social foundations of global financial markets, their operations and impacts on the global power affairs. The thesis highlights the dynamic complexity of the post financial crisis state of the World with its itra- and inter-social features. It instrumentaly uses critique of a free market agenda and neo-classical economy which contrasts the Efficient Markets Hypothesis with Hyman Minsky's Financial Instability Hypothesis (FIH), taking into account the dynamic complexity of financial markets. This approach offers analytical tools that can account for crisis through processes endogenous to contemporary financial capitalism. I shall argue that a financially complex system is, according to the FIH, inherently flawed and unstable. After a theoretical and historical review, the thesis discusses various aspects of the process of austerity regime and its social consequences. This provides an opportunity for analyses of the ongoing existence of interstate competition, of militarised foreign policy, and of other international, at times violent conflicts. In an effort to make sense of some of these phenomena, I instrumentaly use the study of geoeconomics that builds on some fundamental assumptions...

The Basic Income concept in the perspective of Agent-Based modelling
Macháček, Vít ; Janský, Petr (advisor) ; Malovaná, Simona (referee)
The Basic Income concept in the perspective of Agent-Based modelling Abstract: The thesis study the relationship between the basic income introduction and the price level. The basic income would replace the existing social security. The resulting redistribution induce changes in the aggregate demand through the concave consumption function. The aggregate demand in turn affect the price creation mechanism. Because the price level is a result of activity of many different agents with private motivation and information, the work used a simple macroeconomic agent-based model to isolate the relationship. The simulation however did not succeed in isolating the possible link between the price level and the basic income introduction.
