Study of return of heat sources for a family house
Pavlík, Michal ; Lisá, Hana (referee) ; Toman, Filip (advisor)
This bachelor’s thesis focuses on the calculation and selection of the most suitable heat energy source for a selected family house. A brief overview of these heat energy sources serves for a general understanding and clarifies their basic functions. By calculating the heat loss through walls, heated and unheated rooms, functional parts of the building, the ground, and ventilation, the total energy required for heating the house for one year was determined. Additionally, the total energy needed to heat water for 4 people every day throughout the year was also identified. Based on these collected values, four energy sources were selected and subsequently compared with each other in uncluttered graphs. The most suitable heat source was chosen after an economic analysis of return on investment.

Evaluation of combine harvesters John Deere 670i and Claas Lexion 770
JURÁSEK, Martin
This bachelor thesis evaluates the John Deere 670i and Claas Lexion 770 combine harvesters in terms of cost, threshing quality, losses and area performance. The thesis describes the functions of the combine harvesters and their technological description and practical applications. The parameters calculated in the bachelor thesis are pre-harvest and harvest losses, area and weight performance, mass yield, travel speed, crushing quality, fuel consumption and fixed and variable costs.

Contribution to the construction of cost and energy efficient family houses
Čech, Josef ; Mohelníková, Jitka (referee) ; Gašparik,, Jozef (referee) ; MBA, Pavel Slováček, (referee) ; Hrazdil, Václav (advisor)
Dissertation focuses on the verification of construction family houses made of concrete shell block with internal thermal insulation system. The construction technology is transferred to the Czech Republic from France. The work focuses on building envelope. The suitability of implementation is assessed on the basis of verification selected thermal technical requirements placed on building envelope. Requirements are specified by legislation in force in the ČR. The verification was performed by using software simulations and measurements on realized buildings. Critical areas of construction technology were identified on the basis software simulations and measurements on site. It was suggested solution, in which critical areas comply the thermal technical requirements. The building envelope was checked also using the thermography imaging on site. Continuous measurement of interior temperature was used to evaluate thermal comfort in the room. In the completed buildings was tested airtightness of the building envelope, which revealed other critical areas of the building envelope. Critical areas are necessary to solve with sufficient care. The economic cost of implementing each variants of exterior walls made of concrete shell block with internal thermal insulation were compared with the economic costs of implementing external walls made of burnt clay hollow blocks and made of burnt clay hollow blocks with external thermal insulation system ETICS. Subsequently, the economic return was calculated for individual variants of external walls made of concrete shell blocks with internal thermal insulation. From the environmental viewpoint was made comparison of production greenhouse gas CO2 and SO2 (cause acid rains) during the life cycle of the individual variations of exterior walls made of concrete shell blocks with system of internal thermal insulation, exterior walls made of burnt clay hollow blocks and burnt clay hollow blocks with external thermal insulation syst

Economy Efficiency of Road Communications´ Projects
Palčák, Andrej ; Kajánek, Pavol (referee) ; Luňáček, Jiří (advisor)
This master's thesis is focused on solving the issues associated with economic efficiency of construction and operation of road communications' projects. The paper defines significant socioeconomic benefits the operation of the road communications provides for the users and surroundings. It offers a summary of theoretical findings about the economic efficiency's calculation method, analyses the influence of the socioeconomic benefits on the final economic efficiency of the project and based on the results of the analysis it suggests and recommends provisions for investors, compliance of which might ensure implementation of the road communications with high value for future users.

Porovnání žacích strojů ŽTR Pelhřimov 164 a Krone R320
VOKÁČ, Martin
This bachelor´s thesis deals with a comparison of two selected mowers ŽTR Pelhřimov 164 and Krone EasyCut R320 designed for harvesting permanent grassland. The main factors that will be assessed in this work include the economic side, performance and fuel consumption. The comparison will be simulated on three types of farms with an area of 21,3, 170 and 1 700 hectares. The resulting costs associated with mowing will then be converted to 1 tonne of mass.

Traffic accidents under the influence of alcohol and their social consequences on the territory of the Pelhřimov district.
BĚLOCH, František
Traffic accidents under the influence of alcohol and their social consequences on the territory of the Pelhřimov district. This thesis deals with the history of alcohol use and explains the analytical methods for detecting alcohol in blood in traffic accidents. It describes the effect of alcohol on the drivers and its metabolism and defines the current legislation regarding the driving under influence of alcohol in the period 2007 {--} 2008 and the legislation effective from 1.1. 2010. It outlines the status of traffic accidents and traffic accidents under the influence of alcohol, which occurred during the reporting period in the Czech Republic and especially on the territory of Pelhřimov district. The work also deals with social and economic consequences of accidents caused by drunk driving, not just the perpetrators but also the other participants of the accident. Developing the work I have collaborated with experts in the area and used methods of analysis of available materials (including foreign literature), the method of comparative study. I have made retrospective content analysis of data collected in the documentation of traffic accidents of Police of the Czech Republic and Interior Ministry statistics of the Czech Republic using methods of comparative research. The work is, inter alia, specifies the methods of analysis of liability, which was developed to study the influence of alcohol and other drugs on driving ability. The aim was to determine the level of the negative impact of alcohol on the ability to participate in traffic. The second objective was to determine the social consequences of accidents caused under the influence of alcohol for parties to these accidents.
