Renewable energy sources in CR
Sedlák, Pavel ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The content of bachelor study is the technical recherche of the renewable resources of energy in the Czech Republic. I'm ineterested in a kind of renewable resources of energy. This especially contains wind energy, hydroenergy, solar energy and biomass. In each chapter you can find some informations about development, principle of function, technical characteristics, environmental impact and potential in the Czech Republic. At the end of this study are noted economy and legislation especially supports and prices of each renewable resource of energy.

Retrofit Backpressure Steam Turbine
Hlavinka, Miloslav ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
Tématem diplomové práce je revize parní turbíny Mitsubishi a výpočet utahovacích momentů šroubů dělící roviny. Tato práce je rozdělena do několika částí. Úvodní část práce obsahuje seznámení s rozsahem prováděných servisních prací na parních turbínách. Poté je zde samotná revize parní turbíny Mitsubishi. Tato revize je dělena podle jednotlivých komponent turbíny. Poté je zde stanoven seznam nutných oprav a také seznam doporučených oprav pro příští odstávku. V další části je zde shrnut výpočet utěsnění dělicích rovin a to s nebo bez odlehčení. Dále jsou rozebrány nejčastěji používané typy závitů spojovacího materiálu parních turbín. Hlavní částí práce je samotný výpočet utahovacího momentu. Výstupem této práce je poté program pro výpočet utahovacího momentu v programu Excel.

Piston steam engine
Hrbáček, Jaroslav ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
Object of this document is possibility of using piston steam engine (later only SE) in steam boiler plant, heating plant and steam reduction station. There is implemented a thermodynamic suggestion of SE for defined parameters of mechanical power 20 kW, frequency 1500 cpm, input steam pressure 1,5 MPa and warmth inside steam condenser 105 °C. There are implemented the main construction segments of SE with a view to steam distribution system. For determine a shape of work diagram SE (p-V diagram), there was created a supportive programme in Excel. The programme serves as the basis of determination of motor stroke volume and basis of determination of main dimensions.

Steam turbine
Vališ, Petr ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
Goal of this dissertation is design of rotary reduction for entered input parameters that it is connected in parallel with reducing station. Further I´m looking into thermodynamic calculation of stage and chosen parts of turbine, making of project design of connection of rotary reduction to steam circulation. Dissertation is concluded by designed cross-section of turbine.

Single-stage steam turbine
Hrnčířová, Michaela ; Fiedler, Jan (referee) ; Novotný, Zdeněk (advisor)
This bachelor thesis deal with project for single-stage steam turbine specified to the steam reduction station combined thermal cycle. Involvement rotary reduction is elective, to was enough exploited steam power. For the specified parameters was proposed designed the acceptable conception of turbo-generator with a direct connection to an asynchronous generator. The most important part work is the thermodynamic calculation of the flow part whose aim is achieve maximum efficiency and operation of turbines. To increase in efficiency and on the basis engeged turns is considered using of bandage. Also is effected the choice of acceptable steam paddings.

Processing Czech in Python
Novotný, Zdeněk ; Schmidt, Marek (referee) ; Smrž, Pavel (advisor)
This bachorelor´s thesis presents some ways of Czech language processing. The first part contains a general destription of NLTK system. Some of aftermentioned functions were inspired by NLTK functions. There are described functions which attend to inflection and inflexion of various words class in Czech language. Next part is focused on processing of the text in Czech language in which are found and marked each sentences and other parts. Last part describes possibillity of tranformations rules application for each part of text. Results after rules application could be represented graphically.

Steam turbine
Morávek, Tomáš ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
This Master’s thesis deals with the general principles of design and preliminary project work on the tender processing of small industrial, heating backpressure or condensing steam turbine, engine hall for the supplied turboset, perhaps even the other functional units attached to the turboset, such as cooling circuit, condensing system and output of the cable harnesses from the generator. This thesis does not include a condensate preparation, steam production for a new turbine or a measurement and regulation control system.

Backpressure Steam Turbine
Chrástek, Pavel ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The diploma works demonstrates the thermodynamic calculation and design of the geometry flow profile of the back-pressure steam turbine for specified inlet and outlet conditions of steam. Next target of the work is to design the drawing of the turbine axial cross section. Structuring of this diploma work calculation is following: - regulating stage thermodynamic calculation - turbine stages calculation - equalizing-balancing piston calculation - entire turbine intrinsic efficiency and power rating determination - basic calculation of gearbox parameters and RENK-type gearbox selection for turbine and generator arrangement
