The urban development of city Brno, locality Brno-Žebětín
Kratochvíl, Jiří ; Dominik, Vladimír (referee) ; Herzan, Radovan (advisor)
My diploma thesi´s is proposing a new solution for a redevelopment of a former agricultural area and it surroundings which is located in between a residential area Kamechy and Zebetin. The area is outlined by Kamechy from the north, main road Hostislavova from the west, another main road which is going to be build in future based on an urban plan of city Brno from the south and by a natural monument Pekarna and a equestrian zone from the east. The main goal of my proposal is a radical improvement of accessibility and empowering the interconnection with city life. The proposal consists of recreational zones, buildings, equestrian zone and residential buidlings. Very influential element of the proposal is a river Vrbovec which runs throught the area in a east-west direction. The whole stream channel is proposed as a tranquility area which contains today´s greenery and is also going to be improved be a new outplanting of trees and plants in general.

Alternative aggregates based on secondary raw materials from power industry
Kratochvíl, Jiří ; Kalina, Lukáš (referee) ; Opravil, Tomáš (advisor)
The current usage of both classical and fluid combustion ashes is not sufficient and they are deposited in large quantities. The focus of this master´s thesis is to determine and verify some possibilities of their suitable applications in construction industry, specifically as the alternative aggregates for concrete. After the performed analysis several systems based on both classical and fluid combustion ashes have been proposed. Portland cement and hydrated lime were used as admixtures and binding properties of fluid combustion ashes were also tested. The most important properties were compressive strength and bulk density. The aim was to appropriate an optimal ratio between the addition of modifying substance and resulting strength of prepared aggregate in order to correspond to standards for aggregates for concrete.

The effect of boron and its compounds on setting time of portland cement
Kratochvíl, Jiří ; Švec, Jiří (referee) ; Opravil, Tomáš (advisor)
The aim of this work is to study the influence of boron and its compounds, boric acid and borax, on hydratation of portland cement. The first part describes chemical composition of portland cement and reactivity of its components. The second part deals with hydratation of portland cement. The teoretical part ends with description of retardation of portland cement using gypsum or other sulphate options. The experimental part describes preparation of samples – cement paste – modified by addition of boron, boric acid and borax in diferent concentrations. Results are obtained by evaluation of calorimetric curves, mechanical properties and phase composition. The goal is to describe kinetics of targeted slowed down process of hydratation and to find such addition which would suspend setting of boron modified system entirely. Comparison of effects of each boron-containing compound is based on its concentration and on its kind.

Management of Slapy Water Reservoir
Kratochvíl, Jiří ; Syrovátka, Oldřich (advisor) ; Koupilová, Monika (referee)
The topic of this bachelor's thesis is "The management of Slapy Water Reservoir." The aim of this work is to find out the present situation of a natural environment next to this huge water area and suggest recommendations or measures, which would lead to an improvement in this location. We will find out a present situation with an assessment of all microregions (cadastral units), which build together an examined area. The assessment could be done from lots of views. First of all we will find out the situation of ecological stability in all of units, which leads us to finding stability or instability of examined areas, also if they make potencial threat for theirs neighborhoods. Next step will be executed or forthcoming landed treatments, which lead to an improvement in locations, which are ecologically labile. Eventually we will use the index of erosions of an agricultural land, which lead us to complementation of informations about our location. The situation of erosions is caused by wrong usage wiht an agricultural land. We will make a complex chart with all of these minor results and then make an arrangement from worst to best areas. The next step will be to suggest concrete treatments for worst areas. We will also find out an access of residents to theirs regions with all of these steps. This access is not a result of one year reluctance to make the area better, but it lasts long time and is caused by rough usage with a landscape. The result of my work should be used as an information source for next solutions, which will be really expensive, but it will help to get better natural environment for next generations of people.

Využití lineárního programování při optimalizaci svozu separovaného odpadu
Kratochvíl, Jiří
Bachelor thesis deals with the use of linear programming methods in optimization of separated waste collection. The aim is to optimize collecting routes of company KTS EKOLOGIE s. r. o. In the theoretical part are clarified terms which are commonly used in linear programming. In the practical part there are characteristics of the company current status of the problem. The collecting routes are optimized in the program Lingo. In the end, there is a comparison between present routes and the future ones.

The settlement of intra-group supplies in the company
Bedřichová, Eva ; Roun, Vlastimil (advisor) ; Kratochvíl, Jiří (referee)
The aim of my thesis " The settlement of intra-group supplies in the company" is the way of intra-group supplies settling. The first practical part is focused on a description of intra-group supplies, intra-group prices, which are set for the supplies, and settling. Regarding to the analysis of the current settings of intra-group prices, in the second part it is supposed to be found improvement that could bring the company lower costs and higher performance.

Comparison business journalism of Hospodářské noviny, Lidové noviny and Mladá fronta DNES in the beginning of economic crisis in 2008
Kratochvíl, Jiří ; Soška, Milan (advisor) ; Běláčková, Vendula (referee)
The aim of the work is to monitor how three significant Czech daily newspapers Hospodářské noviny, Lidové noviny and Mladá fronta DNES deal with the global economic crisis - the most severe economic situation of the last 80 years. It covers the period from 15 September 2008, when the American bank Lehman Brothers went bankrupt, till the end of the year 2008. The economic crisis very often became the news number one and all three journals focused on it for the whole period. The subject filled not only the economic sections of the newspapers but also pages about news from home and news of the world, sport, culture or even fashion. The work uses a statistical method to evaluate principal criteria. It helps to come to a conclusion which of the three daily newspapers was the best at covering the economic crisis in its early stage in 2008.
