Interval data and sample variance: computational aspects
Sokol, Ondřej ; Černý, Michal (advisor) ; Rada, Miroslav (referee)
This thesis deals with the calculation of the upper limit of the sample variance when the exact data are not known but intervals which certainly contain them are available. Generally, finding the upper limit of the sample variance knowing only interval data is an NP-hard problem, but under certain conditions imposed on the input data an appropriate efficient algorithm can be used. In this work algorithms were modified so that, even at the cost of exponential complexity, one can always find the optimal solution. The goal of this thesis is to compare selected algorithms for calculating the upper limit of sample variance over interval data from the perspective of the average computational complexity on the generated data. Using simulations it is shown that if the data meets certain conditions, the complexity of the average case is polynomial.

Nekonvenční způsoby produkce ropy a zemního plynu a jejich vliv na mezinárodní obchod
Černý, Martin ; Štěrbová, Ludmila (advisor) ; Baláž, Peter (referee)
The growing world population accompanied by an increase in GDP is effectively raising the demand for energy. One of the options are unconventional means of oil and gas, originating mainly from shales and oil sands. The goal of this thesis is to introduce the reader to unconventional means and their influence on international business. After a short introduction and definition an analysis of the situation in the U.S. follows, where the recent years have brought an increase in production from unconventional sources. The positive influence on the economy, employment and energetic security will be mentioned same as possible impacts on the environment. Furthermore the paper provides an analysis of the potential of repeating the U.S. shale revolution in other countries, with special focus on the EU. The success of unconventional sources opens the possibility of new trade routes, influence on the trade balance and the potential of influencing the whole gas market. However, it will also have an impact on current oil and gas producers. Considering the close bond between energetic security and politics, the thesis closes with an analysis of influences on the economy and politics of both -- current oil and gas producers and countries, which might be directly and indirectly affected by changes in the oil and gas market.

Optimalizace struktury výroby a její dopady na vybrané činnosti firmy Granit spol. s r. o.
Černý, Martin
Černý, M. Optimization plan of production and its effects on selected activities of company Granit spol. s r. o. Diploma thesis. Brno: Mendel University In Brno, 2015. The subject of this diploma thesis is to find the optimal plan of production of the company Granit spol. s r.o. using linear programming and subsequently finding the impact of introducing an optimized production structure on finance, ac-counting and marketing activities. For these purposes is created mathematical model, which is solved by Lindo program. Impacts on selected activities are ex-amined through changes in the values of financial indicators, balance sheet items and the ability to meet customers demand.

Source separation and nutrient utilization for elimination of eutrophication of water reservoirs
Holba, Marek ; Černý, M. ; Došek, M.
Sustainable society development and the improvement of water environment quality together with soli quality is tightly connected with separation at source, biodegradable waste and nutrient recycling from wastewater to agriculture. Once we recycle nutrients from wastewater then we can reduce fossil fuel consumption and decrease nutrient input into water bodies. This attitude can be expressed by acronyme NEW (N - nutrient, E - energy, W - water) that lead to the nutrient recycling, energy consumption decrease and enhancement of water quality.

Yield formation of naked and hulled oat
ČERNÝ, Miroslav
On the basis of experiment was performed an evaluation of yield production of the selected spectrum of naked and hulled oat varieties. There were compared time-tested varieties to new varieties registered in the list of recommended varieties in 2013. At the same time were compared methods of yield production of hulled oat and naked oat. After evaluation of real yield was informatively compared the amount of raw food materials obtained from naked oat with the oat rice obtained from hulled oat by hulling machine.

THE SCRIPT AS A WAY OUT FOR ACTING AND DIRECTORIAL STAGING OF DRAMATICAL SITUATIONS
Černý, Matouš ; SCHEJBAL, Milan (advisor) ; DEÁK, Juraj (referee)
This work deals with the problem of staging a dramatic text and with the specific attributes of the director´s work during preparation and realization of a production. It relies on practical experience from practising a bachelor´s production Dorotka. The author focuses on the original text, describes its storyline, structure and style and deals with selected staging alteration. Furthermore he analyzes the space grounded in the text and its solutions chosen for stage design of the production, discusses the problems of working with actors and staging of individual situations and deduces general conclusions, resulting from the entire director´s experience. The author approaches the discussed topic with an attempt to evaluate his bachelor´s production objectively, to name the mistakes and all of the problems that were related to it.

Investigation of Optical Properties of Protective Layer for Glass Medieval Mosaic of Last Judgement from St. Vitus Cathedral in Prague
Valach, Jaroslav ; Kocour, Vladimír ; Černý, Miloš
The Mosaic of Last Judgement from St. Vitus Cathedral in Prague is a medieval masterpiece created in late 14th century by Venetian craftsmen. If very dramatic history and various problems encountered are taken into consideration, the current state of preservation is acceptable, perhaps mainly due to systematic effort to protect the valuable item of cultural heritage. The research project, part of which is presented here, also aims on developing effective means for preservation of the precious object. It concentrates on finding formula for creation of protective layer that eliminates influence of chemicals present in air and in water, while being stable itself. The main goal of the investigation is to help in finding the best formula for protective layer that is most stable itself, i.e. which does not represent a future obstacle in viewing the mosaic, e.g. because of losing its transparency.
