Realistic Model of the Sky
Kussior, Zdeněk ; Bílek, Václav (referee) ; Drahanský, Martin (advisor)
The paper describes a theoretical base and realization of realistic volumetric clouds visualization in an environment of real-time simulator. The first part is concerned with a meteorological background of this problem. I show international classification of ten basic cloud types including a short description and cases of occurence. The following part is concerned with an interaction between cloudiness and simulation core, which is based on the fact, that each cloud acts as a mechanical or an electromagnetic obstacle. This should be considered on some way in simulation. The next part describes technologies and practical implementations of visualization and evaluates their characteristics. Finally, the last chapter describes my implementation and tries to outline project advancement.

Realistic Visualisation of Alcoholic Beverages
Bartl, Vojtěch ; Kučiš, Michal (referee) ; Polok, Lukáš (advisor)
The object of thesis was to make a simple program for visualisation of alcoholic beverages. There was used a global illumination method raytracing, which serve the purpose to visualize 3D scene in photorealistic quality. The rays sent to the scene reflects and refracts on the interfaces and getting information about color of materials. Finally the ray determine the color of pixel. It's a very complicated process where it is necessary to solve passing rays through different interfaces.

things, we(do not) need
Kocúrová, Zuzana ; Sedlák, Michal (advisor) ; Raudenský, Martin (referee)
Kocúrová, Z.: The things we /do not/ need /Graduation Thesis/ Praha 2012 - Charles University in Prague, Faculty of Education, Department of Art Education. Supervisor M. Sedlák. The aim of the graduation thesis is the relation of human and space in the context of philosophy, psychology, social history, art and education. The theoretical part is focused on open and closed space, on their relationship to basic human needs as safeness and solidarity. Individuals apply isolation and control to defeat their fears. The means of open architecture are connected with these issues as well. The second part of my work concentrates on my art projects inspired by the mentioned concepts. My installations, actions and cycle of photographs is described. The third part is focused on applications of these topics in the art teaching. Key words: open space, closed space, fear, safeness, architecture, folding screen, bags, transparency, education.

Factors affecting prey detectability for visual predators
Machalková, Kateřina ; Exnerová, Alice (advisor) ; Javůrková, Veronika (referee)
The cryptic coloration is one of the main ways to protect prey before the visually directing predators. Most animals use two basic strategies of crypsis, background-matching and disruptive coloration. The aim of this thesis was to summarize and evaluate knowledge about different strategies of cryptic coloration. The study was mainly focused on the confrontation between insect prey and predator bird. Experimental studies are comparing the effectiveness of cryptic coloration of prey by a combination of background-matching and disruptive coloration with prey characteristics (inner pattern contrast, background contrast, shape and pattern distribution, symmetry) or background parameters (background complexity, multiple backgrounds, the distance between the prey and the predator) that affect detectability. The results of the study conclude that disruptive coloration pattern in cryptic prey has better effects than the strategy of background-matching. Prey characteristics can affect detectability, but the results of individual studies are not conclusive. Even the background parameters results were unambiguous, the highest efficiency for prey detection time was a combination of disruptive coloration and the background complexity. The issue of camouflage is so complex that the majority of studies do not have...

Physiochemical Parameters of Ponds during Hydrological Year
HUMMELOVÁ, Světlana
Physiochemical Parameters of Ponds during Hydrological Year The aim of this Bachelor thesis was to use the obtained data for the assessment of these physiochemical parameters on growth of the carp. The obtained data and their influence on carp grow were compared with literature. The physiochemical parameters had measured on the 29th June, 16th July, 12th August and 4th October on the Dehtář pond. The followed physiochemical parameters were measured: concentration of oxygen (mg-l-1), temperature of water (°C), pH, transparency (m) and chlorophyll concentration (?g-l-1). It was used calibrated measuring device EXO2 and a Secchi disc. The pond was measured in two transects with focus on depth, inflow, outflow and feeding area. For better evaluation of the results it had included the continuous measurements data from Vltava River Authority, particularly the concentration of oxygen, temperature and light regime. The Dehtář pond is used mainly for intense fish-pond management. Fishery Hluboká manages on this pond. Stock of the pond is polyculture. Dominant fish is common carp, next for example grass carp, pike, pikeperch and catfish. The pond is regular fed, limed and fertilized. From those data, it has produced the spatial and temporal visualisation of basic physiochemical parameters in the pond. From the spatial visualisation follows that the quality of inflow water, depth of water, meteorological situation and position of feeding area had a significant influence on physiochemical parameters. From the temporal visualisation follows that the highest differences in our data were during temperature stratification on 29th June 2016. This day range of the pH was from 7.1 to 9.1. During the other days pH was just about 8. On 29th of June 2016 the range of the temperature was quite high. The temperature was from 19.8 °C to 24.8 °C. Oxygen deficits were very often on this pond. Oxygen deficits had big influence on the death of fishes. The concentration of oxygen went down under the limit values (0.5 mg-l-1) for 2 times during the Vltava River Authority measuring. The local places of low concentration of oxygen had located on the depth of 1.5 m for 25 times during the Vltava River Authority measuring. The Vltava River Authority regularly takes measurements on the Dehtář pond. It should be used for better management and for preventing the critical situation, particularly the drop of oxygen, which could harm the fish. It should be limited feeding, because of the often oxygen deficits.

The influence of the surrounding landscape , fishery management , external and internal factors on water quality in ponds
Janáček, Štěpán ; Vach, Marek (advisor)
The thesis deals with the influences that affect water quality in the ponds . It focuses on selected factors which define water quality . These include e.g. the amount of dissolved oxygen in the water , ammonia, etc. To determine the change in water quality in a fish breeding tank, measured quality of water at the inlet of the tank and at its drain. I enter into the analysis and facts about the amount of fish stocking in ponds , basin shape , location of the pond in the countryside , farming in the watershed .
