Sector ETF portfolio optimization using differential evolution
Holešínský, René ; Čech, František (advisor) ; Kraicová, Lucie (referee)
This thesis examines the use of differential evolution in a real-world portfolio op- timization task based on US stock data. We empirically test the capability of the algorithm to find an inter-sector allocation that outperforms a broad-market stock index. Two constrained sector ETF portfolios are constructed to simulate realis- tic agent-based settings and performance of the competing portfolios is analyzed in terms of both return and risk. The results are further extended to include Markowitz' global minimum variance portfolio and a naive 1/N portfolio. We show that the con- structed portfolios are indeed capable of outperforming the market whilst simultane- ously maintaining lower tail risk, however, the performance significantly deteriorates if the portfolios are rebalanced based on rolling data windows. Overall the algorithm delivers satisfying results while providing the user with a relative freedom when choosing portfolio constraints.

Využití suchého ledu v technologii vín révy vinné
Holešinský, Radim
This Diploma thesis contains information about cryomaceration and using of dry ice in wine technology. Base on that we could compare differences in basic wine parameters or amount of fenolic and sensoric contrasts in mature wines. In theoretical part of this thesis are describe principles of cold maceration or cryomaceration, but main focus was on maceration method with dry ice. In next part we oriented on calculating total costs and usefulness of dry ice. Final part is all about maceration and squeezing of blue grapes. In the beginning of experimental part is described variety Frankovka in general, which was used to this experiments. In following article is explained how the experiment was handled, what practices were used for it and why I chose analytic and sensoric method for this experiment. In Final part are presented graphs, results, conclusions we made in this experiment.

Vliv odlistění révových keřů bílých odrůd na regulaci cukernatosti a kyselin v hroznech
Holešinský, Radim
The main aim of this bachelor thesis was to determine the effect of the defoliation zones to regulate the sugar content of grapes and the content and composition of acids in the grapes. In the introduction describes the meaning and function of leaf area. The following is a description of the composition of the berries, basic sugars and acids, their development in the berries during the growing season and the impact of sugars and acids on wine quality. In the next chapter the importance of agro-technical action contributing to the formation of leaf area. In the end is described defoliation zones grapes. What does it mean defoliation, what are the most appropriate terms, the extent and intensity of defoliation and defoliation recommendations into practice.
