The small hydroelectric power station design
Kokeš, Petr ; Pěcha, Jiří (referee) ; Matoušek, Antonín (advisor)
The thesis deals with comprehensive design of the small hydroelectric power station in the particular site. There is the site description in the first part followed by evaluation of the hydroenergetic capacity of the watercourse and description of the inlet building and piping. Building and machinery part of the turbine hall is described in the next part. The electric part of the power station is worked up to wider scope and includes hydroalternator, switchgears incl. power for self-consumption, electric protections, cabling, transformer substation and high voltage inlet line. There is a description of the control system in the next part and economical evaluation of the investment is at the end.

Design of energetic unit pipeline
Adamec, Martin ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
This diploma work is aimed at a proposal and an overall controll of the pipeline net. There is a preliminary calculation performed (by the analytical method) in this diploma work. There is also a comparison with the numerical computing to find out whether the pipe branch does or does not comply.

Principles and design of project elaboration of boiler islands aimed at piping
Suchomel, Radoslav ; Létal, Tomáš (referee) ; Nekvasil, Richard (advisor)
The Thesis solves the issue of a design and construction of piping specifically focused on boiler apparatus and its equipment. This issue is important for creation of the piping classes in the (PDMS) programmes and for acceleration of output parameters which are mainly the temperature, materials, variable parameters, etc. This leads to other problems such as service life, security, economy, etc., are.

Design and lay-out of high pressure pumping station.
Václavík, Tomáš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design and lay-out of high pressure pumping station with plunger pumps for splash of scales from slabs of hot-rolled. Theoretic (introduction) part of this thesis contain description of formation of scales and description of ways how it is possible remove these scales. And this part contains also explication of effect of water jet on solid material. The practical part of diploma thesis is focused on design of pumping station including of dimensioning of machinery. Part of this work is also technical documentation for proposed pumping station and specification of main machines and devices.

Condensing technology and flue gas
Müller, Jan ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This thesis is developed as a proposal for heating for a primary school and kindergarten in the region of Brno-countryside. For the insulated building, a combination of heating and air-conditioning is proposed. The concept is designed so that the air-conditioning preheats the exterior air and the heating system warms the incoming air to a comfortable temperature. For the required thermal performance, sources of heat (for gas and pellets) and a layout solution for the boiler room is designed. Drainage of combustion products is proposed for both solutions. The project solution is per the extent of the construction permit. The theoretical part is linked with the practical part through the condensation boilers, their function and division, and drainage of combustion products. The experiment for the given topic was conducted on the drainage of combustion products. The pressure loss of the reverse knob was determined in relation to the flow rate of air in the condensation boilers as this loss is essential in assessing the drainage of combustion products.

Technology project for production of part "No.2432-cover"
Bednář, Martin ; Šlais, Miroslav (referee) ; Rumíšek, Pavel (advisor)
The project developed in the framework of Bachelor's study presents a proposal of producing technology of cover "2432", part of the sheet. Based on literature research, the studies and on own experience has been produced this work. The issue of materials, cutting, piping, drawing, design of the tool, evaluation of economic and technological design production has been studied. On the basis of the combined instrument has been designed, constructed according to standards, and the use of existing machinery. To resolve it was accounted economic assessment, which enabled decision-making between the semi-finished products for production. It was found that current production is not economically advantageous, compared to the options proposed. It has been ensured and the complex layout of machines in the area of existing production.

Origin of “rock cities”, pillars and cleft-conduits in kaolinite-bonded sandstone: New insight from study in sandstone quarry where landforms recently evolve
Bruthans, J. ; Soukup, J. ; Schweigstillová, Jana ; Vaculíková, J. ; Smutek, D. ; Mayo, A. L. ; Falteisek, L.
Based on measurements of relative erodibility, ambient and water-saturated tensile strength at natural and quarry exposures three distinct kinds of surfaces were distinguished (erodible sandstone, sub-vertical fracture surfaces and case hardened surfaces). Erosion proceeded along highly fractured zones.
