High Pressure part Steam Turbine
 Martinek, Miroslav ; Ing.Richard Fichtl (referee) ; Fiedler, Jan (advisor)
The target of this work is to created balance comparIsion of versions of high speed and standard speed HP parts of steam turbine and for the more suitable version to make optimization. Optimization consists of flow part, choosen profile blades and construction calculations. Control calculations for rotor and pipeline were made in order to draw longitudinal section of HP part.

Design of high-speed induction motor
 Svoreň, Jan ; Ondrůšek, Čestmír (referee) ; Vítek, Ondřej (advisor)
This work deal with troubleshooting of problem parts of high-speed induction machines. Introduction is about conception of induction machines with reference to construction specialities due to high rpm and because machines are fed by inverter. Next part is focused to design problems. A classical induction machine was measured to determination change of various losses in classic and high-speed induction machines. The computation of laboratory sample high-speed motor was specified for calculation of effective resistance and leakage reactance of solid-steel rotor with copper layer. The results of numerical calculation were validated by using finite elements method and machine design was adjusted for improving operation characteristic.
