Solving of Optimisation Tasks Inspired by Living Organisms
Popek, Miloš ; Peringer, Petr (referee) ; Martinek, David (advisor)
We meet with solving of optimization problems every day, when we try to do our tasks in the best way. An Ant Colony Optimization is an algorithm inspired by behavior of ants seeking a source of food. The Ant Colony Optimization is successfuly using on optimization tasks, on which is not possible to use a classical optimization methods. A Genetic Algorithm is inspired by transmision of a genetic information during crossover. The Genetic Algorithm is used for solving optimization tasks like the ACO algorithm. The result of my master's thesis is created simulator for solving choosen optimization tasks by the ACO algorithm and the Genetic Algorithm and a comparison of gained results on implemented tasks.

Synergetics and Self-organization in the Economy
Balúch, Pavel ; Matušková, Kateřina (referee) ; Janíček, Přemysl (advisor)
The master thesis focuses at analysis and research of synergy and self-organization in economics. The motivation for the thesis was joining Czech Republic and other nine countries to the European Union on May 1st, 2004. The primary aim was to analyse the problem and on a model example,assuming "ceteris paribus", confirm or refute the thought, that joining the European Union has positive synergic effect for newcomers. The second meaning of synergy is solved as a sub-problem in the master thesis, where the use of synergy in logistics was analysed and opportunities improving the current situation were suggested.

Self-organization in today's society
Pampel, Petr ; Malinová, Ludmila (advisor) ; Říhová, Zora (referee)
Main goal of this bachelor thesis is to inform the reader about concept of self-organization in the society including its corporate surroundings. Thesis shortly describes coherent chaos theory for more complex sight of things. Thesis points out penetration of self-organization into human life in daily basis by introducing diverse examples from life. It introduces basic presumptions of a successful manager, who presents the main rival to self-organization. Field test consists of conducted social experiment framed in order to answer submitted hypothesis. Results are supported by processed poll regarding similar matters.

Plant transpiration and self-organization of hydrologic cycle
Šír, Miloslav ; Lichner, Ľ. ; Tesař, Miroslav
We quantified the influence of plant transpiration on the entropy production associated with the degradation of solar energy on the Earth’s surface covered by plants. Two surfaces were studied: (1) biotic surface – plant transpiration taken as equal to the potential one, (2) abiotic surface – plant transpiration taken as if equal to zero. Two sources of entropy were taken into account – the entropy production associated with the conversion of solar radiation into (1) the sensible heat, and (2) latent heat. Surface processes in hydrologic cycle were examined in the experimental watershed Liz located in the Bohemian Forest (Czech Republic). We found that in the growing season 1992 the entropy production in humid hydrologic cycle (the Earth’s surface is biotic) was considerably higher than in the arid one (in 39 % of days the Earth’s surface behaved as biotic, in 61 % of days behaved as abiotic). Considering that the biotic effect on the Earth’s functioning can be assessed using the entropy production, we can assume that the hypothesis that biota – represented as a biotic surface – regulates Earth’s environment is proved in the watershed scale.

Fabrication of periodic stripes based on self-organization of Ni and C60
Vacík, Jiří ; Naramoto, H.
Fabrication of the self-organized mesoscopic stripe system induced by co-deposition of C60 and Ni on the MgO(001) substrate is reported. It was found that a periodic array of stripe domains is formed if specific deposition kinetics is applied. As a possible mechanism of the stripe formation a step-wise relaxation of the internal stress accumulated in the hybrid composite of the immiscible Ni and C60 (a-C) phases is suggested.

Ontology-Driven Self-Organization of Politically Engaged Social Groups
Belák, Václav ; Svátek, Vojtěch (advisor) ; Nováček, Vít (referee)
This thesis deals with the use of knowledge technologies in support of self-organization of people with joint political goals. It first provides a theoretical background for a development of a social-semantic system intended to support self-organization and then it applies this background in the development of a core ontology and algorithms for support of self-organization of people. It also presents a design and implementation of a proof-of-concept social-semantic web application that has been built to test our research. The application stores all data in an RDF store and represents them using the core ontology. Descriptions of content are disambiguated using the WordNet thesaurus. Emerging politically engaged groups can establish themselves into local political initiatives, NGOs, or even new political parties. Therefore, the system may help people easily participate on solutions of issues which are influencing them.
