This master‘s thesis deals with small water power plant Beneš. The first part of the thesis tries to find causes of low efficiency of this power plant. The second part contains suggestions of construction changes for increasing of efficiency – design of new runner blades and basic parameters of new distributor.

The final work elaborated in the scope of master's studies of the branch 2303T002 submitted use of modern technologies in the production of flat sheet metal parts from the material 11 373. Work is set for cold shaping of metal by means of cutting. Production on sequence shearing tool is based on series 350 000 pieces per year. Universal hydraulic press CUPS 63 DEU with shearing force 630 kN is selected for realization. Work is also focused on the production of the same components using plasma, laser and water CNC equipment and the subsequent economic evaluation of all variants of the production. In enclosure there is drawing documentation for cutting tool.

The study of the purchase possibilities of one´s own water jet technology is being conducted in the thesis. The study is aimed at providing a conception in concrete numbers to a particular company, which would help it with making decisions about investing funds in investments to the purchase of one´s own equipment for the water jet.

The aim of this thesis is to design a geometry of runner of high specific speed turbine which is supposed to provide the maximum flow rate of the turbine while achieving a relatively high hydraulic efficiency. New design is based on the analysis of the hydraulic characteristics of three previous design sof very hiát specific speed turbines. The actual hydraulic pdesign of the turbine runner is based on CFD computations. Special software tools like BladeGen and TurboGrid were used for petting up the geometry and mesh for the very first time at Kaplan Department of Fluid Engineering.

This work deals with methods of biogas cleaning to natural gas quality for further use. The introduction is focused on technologies for biogas treatment and biogas management for current situation in the Czech Republic. In the main chapter there is a water scrubber technology design and calculation of the absorption column for the conditions given. A simulation model and preliminary economic balance were then developed on the obtained data.

The main aim of this thesis is the application of ideas to achieve innovation and modernization in the field of design of submersible personal watercraft. Another aim is to show the own creative activity and the ability to move an object from the field of functionality to the field of aesthetics, ergonomics and practicality at an affordable verified techniques, current manufacturing technologies and materials.

The aim of this thesis is to determine the area where there is no random step change in cutting edge roughness. This area is established on the basic of samples created by the abrasive water jet cutting method with variation of technologic parameters.

The aim of this master’s thesis is the optimal design of swirl turbines for small water power plant. It is described a different possibilities of turbine‘s install for locality Vrchlabí. It presents a design of turbines and draft tubes. For the installation of turbines is computed theoretical production of annual electric energy. Furthermore it describes a design of supply channel and intake structure.

The thesis deals with the optimization of production lines cover sheets for external blinds. The aim of this work is to propose appropriate investment in line for expansion of capacity and the reduction of risks in the form of cooperation. To achieve the objective I propose two alternative solutions. Combination of these two variants has been optimized with regard to investment in capacity expansion, reduce risk and achieve a fast return on investment. The conclusion describes the individual prices of investment items and annual profit from the newly formed water jet technology.

The thesis deals with analysis of factors contributing to the development of ephemeral gully erosion on area of the Czech Republic. Method used to direct measurements of ephemeral gully erosion was developed. The statistical sample of gullies was measured to describe the characteristics of ephemeral gullies. Statistical methods were used to compute simple and multiple linear regression models. The models describe relationships between ephemeral gully parameters or factors contributing to development of ephemeral gully. The thesis is concentrated with the development of methodology for prediction the occurrence and prediction of parameters of ephemeral gullies. The methodology can be used to design the optimal erosion control measures in the conditions of the Czech Republic.
