Study of small hydropower station in the locality of pumping station Vřesová
Ullmannová, Iva ; Pavlíček, Michal (referee) ; Dráb, Aleš (advisor)
The aim of the thesis work is the completion of small hydropower plants under the water pumping station refundable Vresova district Sokolov. The grounds are Vřesová settling tank, where the sedimentation of impurities in water technology. The clarified water is sampling the subject and inlet pipe fed into the pumping station, which will use energy potential of water. Energy utilization, water is pumped back into the technological circuit on Vresova.

Alternative Investment Options
Dirhan, Martin ; Bartošek, Vladimír (referee) ; Pavlíček, Michal (advisor)
The bachelor thesis is focused on alternative forms of investment (commemorative coins made of precious metals and French wines- Bordeaux) in comparison with common financial investments available within the financial market (life insurance, additional pension insurance and collective investment). The theoretical part places emphasis on definition of various investment forms principles and highlighting particular advantages and negatives. In the practical part, there are these investment tools analysed and consequently compared.

Fuzzy Model of Investor´s Decision into Photovoltaic Technologies During Pre-Design Phase
Pavlíček, Michal ; Brožová, Helena (referee) ; Čapek, Jan (referee) ; Koráb, Vojtěch (referee) ; Dohnal, Mirko (advisor)
Dissertation deals with fuzzy knowledge base supporting investor’s investment decision into the photovoltaic technologies during pre-design phase, when the engineering solution is not known yet. Probably, majority of investors have particular image about the cost and risk coming from investment into the photovoltaic technologies. However, this image is limited to the restricted knowledge areas of each investor. During the period, when the investor is planning investment into the costly photovoltaic technologies at complex, vague and heavily qualified information about the conditions and risks of investment in the specific region, where the environment is constantly inconsistent and multidimensional, it is possible to solve this complex situation with fuzzy logic. This dissertation is focusing on creation of fuzzy knowledge base with selected installed projects in Europe since 2008 and its use with expert system. Furthermore, is covering the definition and description of the variables, which are included in the investor decision making process. The complete designed architecture of the fuzzy knowledge base is tuned and five projects with different size are tested. The fuzzy knowledge base consists of overall 24 variables and 187 statements.

Quantification of hydrodynamic load on overflowed bridge deck using 2D numerical simulation
Pavlíček, Michal ; Hrdlička, Libor (referee) ; Špano, Miroslav (advisor)
The diploma thesis is focused on a quantification of hydrodynamic load of overflowed bridge deck. Solution was pursued by using two–dimensional numerical simulation of open channel flow in vertical plane created in ANSYS 15.0 software (modules: Workbench, Design Modeler, Meshing, Fluent). Values of drag force, lift force, moment, drag coefficient, lift coefficient and moment coefficient is result of computation. Various types of bridge decks were tested in relation to the degree of inundation (inundation ratio) and flow velocity.The thesis provides comparison of numerical simulation with physical experimental testing and result published in accessible resources.

Approach to the nuclaer safety of the 3rd generation nuclear reactors
Pavlíček, Michal ; Kolář, Jaroslav (referee) ; Kolář, Jaroslav (referee) ; Matal, Oldřich (advisor)
The main target of the master´s thesis is reviewing the generation III nuclear reactors in term of the nuclear safety. At first we have to learn some theory of the nuclear safety in order to understand safety systems of the generation III nuclear reactors. Therefore the thesis is divided into two parts. Legislative and technical approaches to nuclear safety are mentioned in the first part. Regulatory bodies, whose task is to supervise nuclear safety in the nuclear power plants, belongs to the legislative approaches. There are defined terms such as defence in depth, redundancy, diversity, etc. There are mentioned methods to assessing nuclear safety – deterministic and probabilistic methods, especially probabilistic methods, for which a simple example is provided. There are also mentioned active and passive safety systems and their significance for nuclear safety and inherent safety too. There is an example of the function of the active and passive safety systems of the EDU nuclear power plant in conclusion of this issue. The second part deals with description of the selected nuclear reactors in context of the construction of the new units of nuclear power plant in Temelín. The nuclear reactors from companies, which applied for the public tender opened by ČEZ, a. s., for the construction of the ETE 3+4. Thus, the nuclear reactor MIR-1200 by ATOMSTROYEXPORT (Russian Federation), the nuclear reactor AP1000 by WESTINGHOUSE (USA) and the nuclear reactor EPR by AREVA (France) are taken into account . Comparison of the generation II and these generation III+ nuclear reactors necessarily belongs to this master´s thesis. These the generation III+ nuclear reactors are compared with the nuclear reactor VVER 440 (EDU) and in particular with the nuclear reactor VVER 1000, which is operated in the nuclear power plant Temelín. The final chapter contains generally appraisal of the whole problem.

Automation of layoutplanning
Pavlíček, Michal ; Zemčík, Oskar (referee) ; Hlavenka, Bohumil (advisor)
This thesis deal with suggestion of program, which channelize technologist-planner whole tasks which are unit with projection. Deal with capacitive calculation methods and technology projection methods. This methods were implementing in program Excel and AutoCAD. It was reaching configurational guide in html format, which unit whole section of program.
