Characteristics of fan cooling towers
Joska, Jakub ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the problematics of fan cooling towers. The very first part of the text is research, focusing mainly on the theory of cooling and the function of fan cooling towers in general. The following chapter deals with the water resource management of the Dukovany nuclear power plant and the specification of its objects of forced draft cooling towers. The second part describes a computational model created to determine the cooling performance of these towers under the given input conditions. In the following chapters, the results from the computational model are compared with the available data from warranty measurements and with the provided characteristics. The final pages deal with the study of the influence of changes in input parameters on the cooling performance and the research of the behavior of the cooling towers under extreme weather conditions.

Technical and operational factors which has impact to the performance of airports in civil aviation
Květoň, Petr ; Šplíchal, Miroslav (referee) ; Chlebek, Jiří (advisor)
The diploma thesis deals with factors that directly or indirectly affect the operation of the airport. The thesis contains theoretical notes of influencing factors, a list of aircraft and their characteristics, including mutual comparison in graphs. The next part focuses on the airport itself, where it tries to identify the factors that affect its operation, including historical events. The next part focuses on the selection of airports in Central Europe, determining the appropriate performance characteristics, which are then compared and evaluated.

Development of ventilating turbines control
Kremz, Petr ; Jonák, Martin (referee) ; Malášek, Jiří (advisor)
This bachelor thesis describes the design development of mechanical systems of ventilation turbines. The goal of this thesis is to improve the internal control system, the ventilation of the turbine and the system of ventilation air. The output of the work will be the model of the turbine with the regulatory system - the flap in the program Solidworks. Furthermore, the graphical performance of the dependence of the turbine.

Engine Intake Manifold for Formule SAE
Řehák, Ivo ; Blaťák, Ondřej (referee) ; Svída, David (advisor)
Thesis is bend on design of intake manifold for car Formula SAE. For driving of this car is used engine Yamaha YZF R6 (2005). Design of intake tract is processed so that agrees with rules and specifications for cars Formula SAE. For restriction of engine performance is in intake tract installed restrictor. For filling efficiency uplift of engine is used the resonance effect in intake pipes. Analysis of flow is carry out on simulation software for analyses of one dimensional flow.

Vliv pohlaví králíků plemene velký světlý stříbřitý na jatečnou hodnotu
Sysel, Zdeněk
In the literary part, thesis deal with the evolution of domestic rabbit, it´s expansion around the world and taxonomical classification of Lagomorpha order. It is also mentioned actual situation about inland production of rabbit meat and characteristic of broiler rabbit, which is the main product of rabbit breading. In the thesis is description of performance characteristics of rabbits, carcass value and effects affecting carcass value. The thesis describing rabbit meat, benefits of consumption and chemical composition of meat. The end of the literary part mentions the muscular system, skeletal muscles and the basic structure of the muscle fibre. The experimental part evaluates carcass value and deals with the chemical analysis of domestic rabbit muscle and the amounts of fatty acids contained in rabbit meat. The results are compared between the male and female groups. The results are a higher slaughter value, more than 5 %, in the group of females (58 %) and higher slaughter weight in this group. Research has also found a lower amount of intramuscular fat and protein in the meat of male rabbits. Higher amounts of palmitoleic, linoleic and α-linolenic acids are contained in the muscles of females. Other acids - myristic, palmitic and stearic are more contained in the male meat.

Porovnání užitkových vlastností mezi plemeny králíků velký světlý stříbřitý a kalifornský
Sysel, Zdeněk
In the literary part, the bachelor thesis deals with the history of rabbit breed-ing and their quantity in the Czech Republic. It is also mentioned classification of breeds based on their weight and the technology used in small-scale and farm breeding. Next part deal with performance, such as growth rate and car-cass yield. In connection with the performance characteristics, rabbit meat and fur production are characterized. The experimental part describes the comparison of performance character-istics of Californian and Great Light Silver breeds in small-scale breeding. Ob-served animals were weighed regularly from 6 weeks old and slaughtered at 18 weeks old. The Great Light Silver breed achieved better daily growth, on aver-age 35.84 g before weaning and 22.25 g after weaning. The highest growth rates in both breeds were observed in the 7-11 weeks of age. After slaughter, the carcass yield was calculated and the carcasses of both breeds were com-pared again. The average slaughter weight of the California breed was 2262 g and the carcass yield was 54%. The Great Light Silver breed was weighed an average slaughter weight of 2777 g and the carcass yield was calculated to be 56%. The Californian breed excelled in the weight balance of individuals regard-less of gender, the VSS breeds females had better growth ability than males.
