Genetic Algorithm Design for Distribution Network Outfits Optimalization
Ondruš, Tomáš ; Skala, Petr (referee) ; Paar, Martin (advisor)
The work deals with genetic algorithms and their potential use in application software to optimize high voltage switching elements of distribution network. Theoretical part explains the basic concepts of genetic algorithms such as a gene, population and chromosome and basic principles of the development of genetic algorithms.. The main task of the thesis is to design the algorithm that will simulate the distribution of the sectionalizers by telecontrolled section switches or reclosers and analyze how to set the the parameters affecting the convergence speed of genetic algorithm. The basic parameters affecting the convergence of breeding, mutation probability, population size or using of elitism. The second goal is finding a suitable set of input parameters for the selected population sizes without and with using elitism. The results of the work determine the most appropriate settings for each generation and determining the approximate number of generations needed to find the best solution. The genetic algorithm applocation was tested on a less extensive distribution network with six switching elements

Evolutionary algorithms
Haupt, Daniel ; Polách, Petr (referee) ; Honzík, Petr (advisor)
The first part of this work deals with the optimization and evolutionary algorithms which are used as a tool to solve complex optimization problems. The discussed algorithms are Differential Evolution, Genetic Algorithm, Simulated Annealing and deterministic non-evolutionary algorithm Taboo Search.. Consequently the discussion is held on the issue of testing the optimization algorithms through the use of the test function gallery and comparison solution all algorithms on Travelling salesman problem. In the second part of this work all above mentioned optimization algorithms are tested on 11 test functions and on three models of placement cities in Travelling salesman problem. Firstly, the experiments are carried out with unlimited number of accesses to the fitness function and secondly with limited number of accesses to the fitness function. All the data are processed statistically and graphically.

Analysis of possibilities for use of III. and IV. generation of nuclear reactors for the Czech Republic
Gajdzica, Lukáš ; Kopřiva, Radek (referee) ; Kopřiva, Radek (referee) ; Matal, Oldřich (advisor)
The thesis deals with the analysis of possibilities for use of III. and IV. generation of nuclear reactors for the Czech Republic. Introduction deals with basic principles of nuclear energetics and fuel cycle which is closely associated with the issue and its development and application in practice will have a significant effect both for choice of future types of nuclear reactors of IV. generation and the matter of settlement with spent nuclear fuel. In other parts the thesis deals with the present state of nuclear energetics in the Czech Republic, compares concrete chosen types of nuclear power plants of III. generation and generally describes nuclear reactors and power plants of IV. generation. Final part of the work is focused on questions concerning the possibility of construction of new blocks of nuclear power plants in the Czech Republic and presents concrete recommendation from author´s point of view.

Ponava Centre Brno, Královo Pole
Pieleszová, Katarzyna ; Vostrejž, Dušan (referee) ; Odvárka, Antonín (advisor)
The submission of this thesis was preceded by a specialised studio „Brněnské nábřeží a kulturní čtvrť Ponava“. This work focused on a complex urban architectural solution to the area around the former “Jaselská kasárna”, the urban context, transport services, the field configuration etc. The thesis follows this project in a section defined by streets U Červeného mlýna, Staňkova and Střední. The goal of the thesis lies in the creation of an intensive goal – a cultural area, which will offer a high-quality space for intergenerational communication and new social experiences and activities. It newly connects the urban part Ponava with the town center of Brno by a high-quality axis for pedestrian and cycling transport. The project of this cultural area arose after a thorough analysis of surrounding, intercity and global relations as a combination of aims: for children – the elementary art school with graphic and dancing fields, for seniors – leisure time center, and for all together - a multifunctional concert hall and a revitalized area of the former industrial zone of furniture production to a multipurpose intergenerational area with a modern art gallery, offices for young businessmen, architects and artists, and a music club in the basement of the gallery.

Development and perspectives of common rail system
Gach, Jakub ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This bachelor thesis is focused on the Common Rail injection system. It describes the origins of the system, its principle and the function of the individual parts of the system. It also deals with the development of individual system generations and their use. It is clear from the thesis that it is one of the best present-day injection systems that meets all the today's requirements for the design and construction of a vehicle.
