This diploma thesis deals with the thermodynamic design of a backpressure steam turbine. The mass flow of steam through the turbine is determined based on the required heat output, which is transferred in a heat exchanger at the turbine outlet. The governing stage of the turbine is in form of an impulse stage, with optimization of degree of reaction included. During the optimization, a suitable rotor blade was chosen as well as its size. The governing stage is followed by fifteen stages of reaction blading with the stage loading coefficient in the range of 2,75 to 2,80. The governing stage and the reaction blading both meet the mechanical strength requirements. Balancing piston, sealing system and bearings are also designed. Finally, a turbine characteristic is created as well as a longitudinal section. The designed turbine has a speed of 10 000 rpm. While supplying the required heat output, it has a terminal power output of 5 863,4 kW and a thermodynamic efficiency of 84,69 %.

The aim of the diploma‘s thesis is the project of relaying of road II/150 between Domaželice village and the town of Bystřice pod Hostýnem. The road continues on to the bypass of Čechy village and Domaželice village. This bypass is under construction at this time. Relaying of road II/150 is connected on project of Bystřice pod Hostýnem bypass. The connection of the existing and intended roads is designed. The project includes the accompanying report, the drawing part and the photodocumentation. The project is drawning up in two programs called Bentley Inroads and AutoCAD according to valid standards.

Aim of this Master´s thesis is the road adjustment and design of new grade separated junction highway R43 and road I/43,of Černá Hora – Svitávka and to design optimal distribution of transport hubs including the design II/150 and III/37429, which should be connected with existing roads.The adjustment of the routes will be designed in the necessary extent with the optimal distribution of transport hubs regarding the best transport and economical solution and with minimal impact on the enviroment.

Three groups of streams were selected in the area of the Bohemian Massif: the Berounka river with its source streams; the Vltava river with its tributaries the Malše and the Lužnice; the Labe river with its tributaries the Cidlina, the Bystřice and the Javorka. The lithological and tectonical influences to several parameters of the streams were studied. These parameters include: stream gradient, orientation of the stream and sinuosity of the stream. Data were obtained from digital elevation models, aerial photographs, topographical and geological maps. The longitudinal profiles of the streams (in the combination with geological cross-sections), the SL indexes and the gradient/sinuosity graphs were created on the basis of the obtained data. These tools were used for evaluation of the influence of lithology and the tectonics to the streams. The evolution of the streams and the stream-groups was evaluated and compared as well. A strong influence of lithology on the stream gradient was found on most of the analysed streams. The tectonic situation, on the contrary, had strong influence on the orientation of the streams, especially in the resistant rocks. Also, there were selected areas, where was a higher probability of quaternary vertical movements influencing the streams (mountainous areas of the Novohradské...
