Wind power production for small-scale energy supply
Pavlik, Richard ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is the issue of utilization of wind energy. At first, the cause of wind, measuring methods of wind direction and speed and the principle of utilization of wind energy by wind turbines are described. Subsequently, the structure of wind turbines, the construction of wind parks, the development of new types of wind turbines and the possibilities of energy accumulation are introduced. In conclusion, the concept and the economic evaluation of wind powered system for small scale energy supply is analyzed.

Retrofit IP-LP Section Steam Turbine 300MW
Pavlik, Richard ; Fichtl, Richard (referee) ; Fichtl, Richard (referee) ; Fiedler, Jan (advisor)
The aim of this master’s thesis is a retrofit of condensing three case steam turbine K300-170 with reheating. In the first part, the heat balance of the system is calculated for given parameters. The design of the flow section is focused on the combined intermediate pressure and low pressure turbine section and it consists of defining rotor and blading characteristics. In the stress control, the stress of the designed blading is checked and for the conclusion the shaft seal losses and their effect on the overall output power of the turbine are estimated. The drawing of axial section of combined intermediate pressure and low pressure turbine section is also included in the thesis.

What Is Life and the Definition of Life in the Heart of Science of the 21st Century.
Pavlík, Richard ; Lhotský, Josef (advisor) ; Šolc, Roman (referee)
Phenomenon of life exceeds the science. Definition(s) of this concept should be a basis. This work discusses many sights around the definition of life and searching for the essence of life and it tries to embrace these factors in their entirety by quoting both traditional definitional approaches and the less traditional ones and possibly even futuristic ones. In a shortcut this text analyse instructions on how to define. Considering the extensiveness of the topic this bachelor's thesis touches thoughts of the scientific interdisciplinary framework. Keywords: definition of life, life and non-life transition, anti-definitionism, autopoiesis, cybernetical approach, biosemiosis
