Optimization of an Adapting Pipes
Svozil, Jan ; Drábková, Sylva (referee) ; Katolický, Jaroslav (referee) ; Štigler, Jaroslav (advisor)
Adapting pipes are a significant part of any pipe-line network and they are the sources of substantial hydraulic losses. They are designed for a manufacturing simplicity, regardless of flow. This paper concerns with lowering of hydraulic losses of adapting pipes by means of the shape optimization. Several methods of a mathematical optimization are tested and due to the complexity of the task and the need of the computational distribution among several computers, the gradient based algorithm is used. These methods loop together with a CFD software then automatically explore the design space. Several optimizations of diffusers with different opening angles, shape parameterizations and boundary conditions are made for the better insight on hydraulic losses. In three chapters there is description of development of parametric description of bend by means of Bezier surfaces. At the end optimum shape is found with hydraulic losses were decreased about 22%, which was not validated by experiment. In the final chapter is application of developed software on the shape optimization of Kaplan draft tube.

Pump design
Mizera, Ladislav ; Svozil, Jan (referee) ; Klas, Roman (advisor)
This thesis considers the characteristic of hydrodynamic pumps. It describes the activity of these pumps and it shows the particular characteristic curves. Then the hydrodynamic pumps are divided and described. The biggest attention is attended to the vertical multistage centrifugal pump and shaft seal.

Distribution Pipe of Pelton Turbine
Halabrin, Robin ; Svozil, Jan (referee) ; Štigler, Jaroslav (advisor)
This bachlor’s thesis describes problems of concept distribution pipe of Pelton turbine and it shows other ways it’s possibly simplify this pipeline. There is compared the version made of welding plate with the other version made of welding pipes. The aim is the cost analyse and hydaulic optimalization.

Regulatory reform and systemically important banks
Svozil, Jan ; Blahová, Naděžda (advisor) ; Kaimova, Nadira (referee)
The master's thesis deals with the topic of the regulatory reform based on Basel III framework created by Basel Committee on Banking Supervision. The target of this thesis is to present tools and components of Basel III standard and focus on the identification and analysis of the key factors for classifying banks as systemically important. The issue is described from global perspective and special attention is given to European specification of regulatory rules. One part of this study is dedicated to the monitoring of the fulfillment of new regulatory rules and tools by global and European banking system. Diploma thesis includes also the chapter monitoring macroeconomic impact of regulatory reforms.
