L Systems and Their Applications
Koutný, Jiří ; Goldefus, Filip (referee) ; Meduna, Alexandr (advisor)
This master thesis describes deterministic context-free L-systems and its context in procedural modeling, especially in fractal geometry, deals with rewriting technique and its usage for modeling structures similar to plants. Further it describes more complex types of L-systems, especially their context and parametric variations, and shows usage of L-systems in computer graphics and describes its usage for procedural modeling of architecture. At the end of this thesis there are described some other possibilities of usage procedural modeling with L-systems and introduced some extensions of rewriting rules, which will be subject of future research.

Characterisation of the Physical Chemical Processes Using the Fractal and Harmonic Analysis
Haderka, Jan ; Nešpůrek, Stanislav (referee) ; Mikula,, Milan (referee) ; Zmeškal, Oldřich (advisor)
Existuje mnoho různých způsobů jak analyzovat disperzní systémy a fyzikálně chemické processy ke kterým v takových systémech dochází. Tato práce byla zaměřena na charakterizaci těchto procesů pomocí metod harmonické fraktální analýzy. Obrazová data sledovaných systémů byly analyzovány pomocí waveletové analýzy. V průběhu práce byly navrženy různé optimalizace samotné analýzy, převážně zaměřené na odstranění manuálních operací během analýzy a tyto optimalizace byly také inkorporovány do softérového vybavení pro Harmonickou Fraktální Analýzu HarFA, který je vyvíjen na Fakultě chemické, VUT Brno.

Map Generator and Path Search in a Map for the Strategy Games
Karásek, Štěpán ; Mráček, Štěpán (referee) ; Orság, Filip (advisor)
This thesis consists of two parts. The first part deals with procedural map generation aiming at terrain generation. For the most part, the bases of terrain generation, usable algorithms and the ways of generating other landscape elements are followed up. A terrain generator using diamond-square algorithm is then implemented and integrated into the existing game engine. The second part of the thesis analyses the pathfinding problem, describes usable algorithms and one of them in detail. Furthemore, the post-processing of the path is being solved and possibilities of hierarchical pathfinding algorithms are presented. Pathfinding using A* algorithm is also implemented and integrated into existing game engine. Finally, functioanality of both the algorithms is demonstrated in an interactive application.

Water Flowing in the Landscape Visualization
Vlček, Adam ; Pečiva, Jan (referee) ; Seeman, Michal (advisor)
This work covers visualization of water flowing in the landscape with focus on displaying the results in real time. For in order to obtain data for visualization also common procedures for artificial terrain and natural looking textures are introduced, as well as simple water flow simulation algorithms. The final objective of this work is to present an interactive environment, which will offer interesting visual output in direct response to the user.

Generator of 3D Objects Based on L-Systems
Kvita, Jakub ; Solár, Peter (referee) ; Vrábel, Lukáš (advisor)
The aim of this bachelor thesis was to create an interactive system for generating 3D models. The generator is based on L-systems as a kind of formal grammars and turtle graphics for 3D modeling. The application was created in Java SE using JOGL library as access point for OpenGL and rendering. The thesis analyze the theoretical basis of L-systems, turtle graphics and rendering 3D objects and then describes creation of application using the acquired knowledge.

Ornament in Nature, Science and Art. Discourse Analysis of an Education Case Study
Havlásek Tatarová, Lucie ; Fulková, Marie (advisor) ; Machalický, Lukáš (referee) ; Zindulka, Ondřej (referee)
The dissertation thesis, Ornament in Nature, Science and Art, deals with the theme of ornaments in contemporary art, design and architecture. Individual chapters are dedicated to exploring nature and science as sources of inspiration for contemporary art. The chapter, Body and Ornament, is about ornaments for the human bodies and patterns created from the form of human bodies. Art creations by the author and her students make up an integral part of the main text. An individual chapter is dedicated to the Bodyornament project. Bodyornament is a project involving artistic, educational and research elements. Its primary body of work took place as an art performance in the Veletržní palace in Prague. Through the active participation of the students, patterns and ornaments made from their bodies were created. The process was documented by means of photography. The photographs together with the students' written reflections about the experience comprise the primary research documents. In this dissertation, these documents were analyzed and interpreted by using a combination of specific forms of qualitative research and art-based research. Our research model was based on three degree reflexive analysis according to Donald Schön. Through interpretation of the research results, thoughts of possible...

Compression and Quality Assessment of ECG Signals
Němcová, Andrea ; Tkacz,, Professor Ewaryst (referee) ; Kudrna,, Petr (referee) ; Vítek, Martin (advisor)
Ztrátová komprese signálů EKG je užitečná a v současnosti stále se rozvíjející oblast. Stále se vyvíjí nové a nové kompresní algoritmy. V této oblasti ale chybí standardy pro hodnocení kvality signálu po kompresi. Existuje tedy sice mnoho různých kompresních algoritmů, které ale buď nelze objektivně porovnat vůbec, nebo jen zhruba. V oblasti komprese navíc nikde není popsáno, zda mají na výkon kompresních algoritmů vliv patologie, popřípadě jaký. Tato dizertační práce poskytuje přehled všech nalezených metod pro hodnocení kvality signálů EKG po kompresi. Navíc bylo vytvořeno 10 nových metod. V rámci práce byla provedena analýza všech těchto metod a na základě jejích výsledků bylo doporučeno 12 metod vhodných pro hodnocení kvality signálu EKG po kompresi. Také je zde představen nový kompresní algoritmus „Single-Cycle Fractal-Based (SCyF)“. Algoritmus SCyF je inspirován metodou založenou na fraktálech a využívá jednoho cyklu signálu EKG jako domény. Algoritmus SCyF byl testován na čtyřech různých databázích, přičemž kvalita signálů po kompresi byla vyhodnocena 12 doporučenými metodami. Výsledky byly porovnány s velmi populárním kompresním algoritmem založeným na vlnkové transformaci, který využívá metodu „Set Partitioning in Hierarchical Trees (SPIHT)“. Postup testování zároveň slouží jako příklad, jak by měl vypadat standard hodnocení výkonu kompresních algoritmů. Dále bylo statisticky prokázáno, že existuje rozdíl mezi kompresí fyziologických a patologických signálů. Patologické signály byly komprimovány s nižší efektivitou a kvalitou než signály fyziologické.

Perception of beauty - biological vs. cultural determinants
Obdržálková, Zita ; Soukup, Václav (advisor) ; Soukup, Martin (referee)
This thesis deals with problems of biological and cultural determinants influencing perception of beauty. It attempts to find out if there is a common biological basis of perception of beauty or if beauty represents merely a sociocultural construct - product of a specific culture. With respect to biological determinants it concerns biological processes significantly influencing perception of beauty. In this context, these processes include probably innate evolutionary adaptations, effects of brain cognitive systems and neural correlates processing perceptions of beautiful objects. In connection with cultural determinants it presents studies emphasizing cross-cultural differences in perception of beauty. Further subject of the thesis is an aesthetic conception of subjective and objective beauty and related concept of beauty based on mathematical relations. In this connection, the creation of universally beautiful objects based on fixed mathematical rules as well as the possibility of exact measurement of beauty are discussed.
