Thermal baths Yverdon, five senses in architecture
Pospíšil, Tomáš ; Uřídilová, Marcela (referee) ; Koleček, Ivan (advisor)
Peace in the shadow of the trees. A spring coming up from depths. The spa park is an island at the edge of the town. It is the highest value of its surroundings. That is why I place the volume of the spa on the side of the park along the road. There is a promenade connecting the constituent elements of the building. Full, heavy masses alternate with airy and bright ones. The park grows through the buildings, and in this way the spa and the park become closely intertwined. The interweaving of the built and the natural as the central theme of the project.

Trasfer Heat Analysis in Steam Generators in blocks of VVER 440
Roupec, Petr ; Pulec, Jiří (referee) ; Šen, Hugo (advisor)
The aim of this thesis is to analyze the heat transfer in steam generator of blocks in the nuclear power plant VVER 440. The steam generator represents the border between the primary and the secondary circuit. The heat is carried from a warm water from reactor to a cold water. The steam arises after the heat transfer and drives the steam turbine. An important quantity which represents the heat transfer is a heat transfer factor. This thesis is divided into theoretical and a practical part. In the theoretical part is mentioned a principle of the steam generator and the theoretical calculation of the heat transfer factor, which comes first of all from the character of the streaming in the steam generator. The practical part brings a comparison of the heat transfer factor calculated from data measured after the start of the third block of EDU in 1986, with the heat transfer factor which comes from the measurement after the power-increase for 105 % of nominal power of the same block in 2009. Further is shown the prediction of the heat transfer factor for next power-increase and the following service is shown too.

Magnetic field effect on the flow character close to the surface
Buday, Jakub ; Šedivý, Dominik (referee) ; Fialová, Simona (advisor)
The aim of this bachelor´s thesis is to discribe basic properties of flow and magnetic field. Further characterize different applications of magnetic fluids. Also discribes the influence of magnetic field on some properties and behaviours of water. This thesis is comparing several conlusions of scientific articles, that are examining this subject. In the experiment the changes of three fluids were observed by the help of high speed camera. The contact angle of fluids before and after exposing to magnetic field is compared. In the second part of the experiment behavior of flowing drop through magnetic field is observed.

Sustainable energy sources
Doležal, Jan ; Nerud, Pavel (referee) ; Škvařil, Jan (advisor)
This bachelor’s thesis is a recherche dealing with sustainable energy sources. It lists and describes the various sources and shows their operating principles. In the last part it evaluates their current use in the Czech Republic and the possibilities for further development from economic and technical point of view.

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.

Infiltration - the elementary hydrological process
Salač, Jan ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
The bachelor thesis deals with the evaluation of water infiltration into the soil in the area of interest of the village Šakvice. Measurements were carried out on 13 May 2009 and 10 September 2009 on arable land with convential tillage (with ploughing). For measurements were used double ring infiltrometers. To evaluate the cumulative infiltration and infiltration rate were used equations of Kostjakov, Mezencev, Philip and three-parameter equation of Philip‘s type. The results were processed numerically, plotted and then compared.

Lake under Petrov - architectural and urban development of a space at the corner of streets "Biskupská" and "Petrov" (in a relation to the underground of Brno)
Zdražilová, Jana ; Pech, Zbyněk (referee) ; Kopáčik, Gabriel (advisor)
Solution idea Petrov is stoney bill in south-west part of Brno. You can find magnificent cellar on given land that is probably medieval and is partially carved in rock. Designed building follows up this rock developing to surface, where crystalizes and gradually grows and expands towards from „Šilingrovo náměstí“ to St. Petr and Pavel’s cathedral. Water is the other element – it wells from mouldering diabas rock to surface, thanks to cracked springs that can be found here. That creates a lake beneath Petrov. Water theme is projected to building interiors. This construction is characterised by great views, which are possible because of unique location of the site and the building itself is designed to use the most of them. From terrace, caffeteria and also multipurpose hall can anyone view cathedral, Zelný trh square and Parnas fountain. Function locations 1) Interest-activities more people more life. There used to be one of the oldest schools in Brno from half of 14th century. And because of that, although in modified form, I wanted to preserve this function of the place. I designed one classroom and a multipurpose hall, that can be used e.g. for dance lessons or - in a daytime, when there be no usage for the hall - for rentals for commercial purposes. 2) The entrance to medieval cellar carved into rock, that is under the site. There are two functional water wells, that constantly floods the cellar space. Water will be pumped out to terrace, where it will make a small lake. The whole space will function as a small gallery. 3) Caffeteria and sweetshop are located on very attractive place with spectacular views. Adjoining terrace will serve as summer garden that can be used by public all year round.

Waterjet cutting of material
Veselý, Radek ; Foldyna, Josef (referee) ; Habán, Vladimír (advisor)
This bachelor thesis describes principles of utilization of high-speed liquid jet for material machining. In the first part, basic classification of liquid jets and brief description of devices for generating high pressure liquid is presented. Next, using of continuous jets is discussed. Main scope of this work is oriented at the use of so-called pulsed jets, especially at ultrasonically modulated ones. Break-up of ultrasonically modulated high-speed pulsed jet into single pulses, impact of such pulse on the surface of disintegrated material and subsequent erosion in the impact area are described. The comparison of efficiency of modulated and continual water jets is summarized in the last part of the thesis.
