Realtime Weather in a Landscape Visualisation
Vlček, Adam ; Jošth, Radovan (referee) ; Seeman, Michal (advisor)
Thanks to the increasing computation power the complexity and dynamism of virtual reality is continuously improving. This work aims to examine influences of weather in a landscape and the means to simulate and dynamically visualize them in real time on the current personal computer hardware. The main goal is to find quick well looking approximations rather than a complex physically correct simulation. The work covers using modern programmable GPU not only for visualization but also as a powerful simulation instrument. The main topic is water movement in the terrain and its effects on it like erosion, snow melting and moisture impact on vegetation. This requires dynamic terrain texturing and algorithms supporting fast geometry and normals updates.

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.

Atmospheric Phenomena
Radouš, Jakub ; Milet, Tomáš (referee) ; Kobrtek, Jozef (advisor)
This bachelor's thesis deals with a visualisation issue of several atmospheric phenomena by means of the OpenGL library. The work contains theoretical bases for rain, snowfall, lightning, fog, wind, tornado and rainbow, which are further converted to the form of algorithms. The outcome is an application with graphical user interface that is able to display seven natural phenomena set in a landscape.

Small snow cutters
Ráheľ, Dušan ; Prokeš, František (referee) ; Brandejs, Jan (advisor)
The bachelor thesis deals with the subject of snowblowers. It describes their origin, evolution a current applications. It presents development and technical details of all snowblower sizes, ranging from smallest ones, driven manually by operating personal, to the largest, attached to the trains. The work explains modern hybrid snowblower powertrain. The combination of gasoline and electric engine proves to achieve substantial reduction of fuel consumption at unaffected efficacy of snow removal. The second part of work deals with our proposed novel method of snow removal, which employs its volume compression. A series of experiments were done in order to establish the relation between the exerted force and resulted compression of snow of various initial mass density. We have found that pressure smaller than 0,5 MPa is capable in average to reduce the snow volume to 45% of the initial value.

Dynamic analysis of structure loaded seismic loads
Havlíková, Ivana ; Nevařil,, Aleš (referee) ; Vlk, Zbyněk (advisor)
The purpose of my master’s thesis is the solution steel hall with concrete columns, that is loaded by an earthquake. This simulation program was used RFEM. To calculate was used the spectral and temporal analysis, and that on models of structures with several combinations of materials. The analysis was performed for both the general direction of the earthquake, so for combinations of directions according to standard procedures in EC8.

Snow blower as an accessory for a small loader
Diviš, Přemysl ; Hloušek, David (referee) ; Škopán, Miroslav (advisor)
This bachelor's thesis provides the construction solution and a proposal of a snowblower as additional equipment to a skid steer loader. The project contains research on the construction of these devices, a description of the individual parts of the snowblower, and a functional calculation of the basic parameters needed for the selection of hydraulic motors. Furthermore, a strength check of important parts is performed, especially on the auger. As a part of the thesis, there is also drawing documentation of the snowblower and the welding auger.

Realistic Visualization of Snow
Chukir, Patrik ; Polášek, Tomáš (referee) ; Čadík, Martin (advisor)
This diploma thesis follows visualization of snow formations, which are called penitentes. This work includes also collecting the data needed to derive the optical properties of the penitentes material. Which are different phases between snow and ice. For visualization method is used Progressive Transient Photon Beams, that this work implements with the help of SmallUbpb.

Contaminated Runway Operations
Michna, Tomáš ; Hammer, Jaromír (referee) ; Šošovička, Róbert (advisor)
This bachelor thesis solves problem of operation from contaminated runway. It lists individual kind of contaminant and describes measuring, which is doing on contaminated runway. It also deals with devices for measuring friction coefficient runway surfaces. There are also the methods, which publishing informations about state of runway. At the conclusion compares the limits that are affected by contaminated runway.

Space structure of industry building object
Pelikán, Adam ; Švaříčková,, Ivana (referee) ; Šimůnek, Petr (advisor)
The subject of this project is the structure of the storage hall which is made of reinforced concrete. It is designed as precast frame (span of 18m), founded on pocket footings. The roof deck (non-rigid) consists of ribbed slabs. The cladding is made of sandwich panels (reinforced concrete and isolation) layed on foundation beam. The design is focused on the single typical frame. Roof girder, column and pocket footing are designed. Designed life of the structure is 50 years.
