Measurement of induction machines
 Sporni, Peter ; Huzlík, Rostislav (referee) ; Janda, Marcel (advisor)
This work dissert about problematics of induction engines, which are the most used types of electrical drives used in present time. At the beginning we will explain their construction and its influence to the characteristics of the engine and possibilities of their regulation. In the next part we will describe some basic types of measurments implemented on these engines. To verify the theory which was described in this work we will discuss measurments realized on concrete types of engines. At the end we will calculate the main dimensions for one of the measured engine.

Preliminery results of flow measurements in an elbow pipe of circular cross-section
 Uruba, Václav ; Jonáš, Pavel ; Mazur, Oton ; Hanus, D.
A few results of experiments on secondary flow in curved pipe of circular cross-section are presented. The experiments have been carried out using a 5-hole pressure probe. comparison of the case of low-turbulent top-hat profile elbow inflow and fully developed turbulent channel flow has been made. the secondary flow effects have been found to be much stronger in the developed inflow case.
