Procedural Texture Generator
Doroshenko, Ilya ; Karas, Matej (referee) ; Milet, Tomáš (advisor)
Textures are an essential part of modern 2D and 3D rendering. The most prominent texturing techniques are Texture Mapping and Procedural Generation. Both techniques have their set of demands on computational resources. Procedural generation provides rich detail resolution without memory consumption, but also requires processing power. Texture Mapping is quick to process, but images, that the texture consists of are using a lot of space in memory and have finite resolution and sets of complications around algorithms that try to overcome that problem. This thesis discusses techniques of texture generation their interchangeability and applications. Result is an extensible application, that can produce texture maps from algorithms and can export algorithms to be used in procedural shading techniques.

Rendering of Voxel-Based Scenes Using Real-Time Ray Tracing
Menšík, Jakub ; Milet, Tomáš (referee) ; Matýšek, Michal (advisor)
The aim of this work was to create a program to visualize voxel scenes in real time using ray tracing. It included the study of various methods of such a rendering with a focus on shadows. The solution was created using Unity engine and experimental packages Unity Jobs and Burst. The thesis presents multiple ray tracing passes and SVGF technique, that is used to turn a noisy input into full edge-preserving image. The final program is able to render hard shadows, soft shadows, and ambient occlusion at speed of fifty frames per second.

Ecological differences between herbs and woody plants, and evolution of the herbaceous habit
Klimeš, Adam ; Herben, Tomáš (advisor) ; Lens, Frederic (referee) ; Těšitel, Jakub (referee)
Ecological differences between herbs and woody plants, and evolution of the herbaceous habit Adam Klimeš, doctoral thesis Abstract Flowering plants (angiosperms), which make up most present-day vegetation, were originally woody. While flowering plants have repeatedly given rise to herbaceous lineages since their first appearance, we lack a clear explanation for these common evolutionary events. Freezing temperatures and drought periods have been proposed as factors which had caused huge success of the younger growth form but the evidence is very limited and not in favour of these hypotheses. In this thesis, we aimed to build the foundations of research on the evolution of herbs. We outlined new potential drivers of the evolution of herbs, suggested solutions to some methodological challenges and provided evidence about differences between herbs and woody plants relevant to the hypotheses on herb evolution. To this end, we used common garden experiments with young plants of both growth forms and global trait data from public databases which we evaluated using phylogenetic comparative techniques. Annuality of aboveground biomass and fast life-strategy of herbs are characteristics which differentiate them from woody plants and which in some conditions are expected to be behind their success. Apart from the...

Ecology of critically endangered \kur{Sedum villosum}-experimental study
DILLINGEROVÁ, Hana
The aim of this diploma thesis was to elaborate a literature survey and especially to conduct an experimental study of ecological demands of the critically endangered species Sedum villosum. The localities, on which S. villosum formely occurred, disappeared largely because of habitat destruction by draining and plowing of wet meadows, or by the abandonment followed by development of high vegetation and biomass accumulation. Therefore, this work could contribute to the knowledge of shadow influence and surrounding vegetation concurency on seed germination and flowering of this species. Retrieved knowledge can be later used for rescue program realization (repatriation options, strengthening populations, habitat requirements). The experiments showed a significant negative effect of the shading and the presence of surrounding vegetation (sedges, brown mosses and peat mosses) on germination and flowering of S. villosum. Furthermore, it was found that S. villosum is able to germinate directly on water surface, with seed germination even higher than on wet soil. The experimental sowing, planting and subsequent monitoring of germination, growth and survival of S. villosum at the rehabilitated area of Knížecí Pláně (NP Šumava) showed that it is possible to strengthen S. villosum population by sowing and planting autochthonous material on prepared areas with a torn down turf. As an acceptable tools seems to be using mulch from mown in the area of the original population. Similar process can be used in the future for restoring historical localities of this species.

The systems of building services in immovable heritage
Maurerová, Lenka ; Vlček, Milan (referee) ; Kabele,, Karel (referee) ; Doc.Ing. Martina Peřinková, Ph.D (referee) ; Hirš, Jiří (advisor)
The present PhD. thesis deals with the systems of building services (namely heating, ventilating and air conditioning, shading) which provide required indoor microclimate inside the immovable heritage. The work thus combines the exclusively technical field of building services (BS) and the general principles of heritage conservation. The aim of my PhD. thesis is the analysis of immovable heritage conservation processes, focusing on the current state of research and BS systems documentation. Furthermore the work concerns the possibilities of temporary measurements of indoor climate parameters inside the immovable heritage, and aims to develop a computer model (in BSim software) for the simulation of various working conditions in the selected buildings. For the stated aims were selected three representative historic houses: historical assembly hall at the Faculty of Civil Engineering, Brno University of Technology; the Palm Greenhouse at Lednice Chateau in Moravia; and Villa Tugendhat in Brno. These buildings had been surveyed for several years, and in this PhD. thesis I present their analysis, evaluation, and conclusions. The aims of this PhD. thesis broadly correspond to the transnational objectives. The present research is, for example, in accordance with the international document ICOMOS Charter (Zimbabwe, 2013) which is concerned with the analysis, conservation, and restoration of architectural heritage. The research of immovable heritage is also supported by European Union, e.g. by the Seventh Framework Programme of EU.

The Swimming cetrum Brno Zidenice
Pleva, František ; ing.arch. Lukáš Ležatka, Ph.D (referee) ; Pavlovský, Tomáš (advisor) ; Petříček, Tomáš (advisor)
The main theme of this project is a concept of the Swimming centrer in Brno—Židenice. The plot in question is extremely complex. It is located on the edge of a hillside near the Health center at Viniční, which naturally dominates the area by the shape and size of its structure. The underlying idea was to use orthogonal shapes to create a building, that would not compete with the Health center but would add up to its surroundings instead. Every single part of the project was designed to delicately fit into given terrain and surroundings. Most of the functions of the building are set on the 1st floor (e.g. locker rooms, two bars, water world and wellness). The 1st underground floor features technical services rooms. On the 2nd floor, there is only a swimming pool and a terrace with whirlpools on one part of the roof. The roof top offers an excellent view on the city of Brno. South and west facades of the pool hall are made completely out of glass. It is covered by vertical curved aluminum lamellar system. That is because of the thermal technical requirements of the building, however, it is also a dynamic piece of the facade that adds up to aesthetic finish of the building. The construction is based on a combined system of monolithic reinforced concrete columns and walls and glue laminated timber beams and frames. The roofs are compact and green. In the part above the locker rooms is intense green roof planted intensively green fully-grown greenery.
