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

Molecular aspects of interspecific hybridization of sturgeons related to polyploidy and in situ conservation
HAVELKA, Miloš
Sturgeons (Chondrostei: Acipenseriformes) display markedly disjunct distributions with a wide occurrence in the northern hemisphere. Their unique benthic specializations, conserved morphology, evolutionary age, the variation in their basic diadromous life history, and the large public interest due to their near extinction or critically endangered status make sturgeons and paddlefishes one of the most interesting group of vertebrates. In addition to that, ploidy diversity of Acipenseriformes possessing three ploidy groups having ~ 120 chromosomes, ~ 240 ? 270 chromosomes and ~ 360 chromosomes provides unique model for investigation of evolutionary processes which were going through the genome duplication events. Sturgeons are also notoriously known for their strong propensity to interspecific and intergeneric hybridization which can result in hybrids with various ploidy levels. All these facts make sturgeon genetics and cytogenetics a thriving but also complicated area for research. In the present work, the role of genome duplication and functional reduction evens in evolution of sturgeon species as well as sturgeons? ploidy levels and ploidy relationships among Acipenseriformes were investigated using molecular markers. In addition to that, clarification of origin of abnormal ploidy levels and observation of segregation pattern of microsatellite alleles in the course of hybridization of polyploid sturgeon species were included into this study. With regard to the all considerations and observations provided by this study we concluded that evolution of sturgeon species is still widely dynamic and ongoing process which might goes through the allopolyplodization as well as autopolyplidization events.

Design and implementation of instruments for monitoring and evaluating physical activity of insects
KAKAŠ, Štefan
The aim of the diploma thesis is the development and subsequent construction of the device whose function is measuring and evaluating physical activity of insects. This instrument is unique in the Czech Republic and will be able to record physical activity of insects by using a video camera. Later that it will be able in this video shot back to reconstruct kinematic and statistical data about the movement of insects with software which is developed with Visual Basic .NET. On the base sufficient od obtained data it can be used to verify the premise of biologists about nervous systém, brain function and behavioral of Drosophila Melangostar which is more than a century used as model for genetics experiments. Finally, the conclusion compares the result of previously known and available software solutions in the world of biology, which are still used as a source for the results of performed experiments.

Congenital disorders in horse
PRANTLOVÁ, Veronika
The task of this thesis is to elaborate literary study of congenital disorders incidence by horses. At the beginning, there are summarized problems of congenital disorders in general, such as origin of the disorders and the forming factors. Further, the most common or the most severe equine congenital disorders, considering specific prevalence depending on the breed, are specified. The thesis also contents the incidence of congenital disoders by other kinds of domestic animals. At the end the practical breeder´s advices are summarized.
