Design and optimalisation of synchronous reluctance machine
 Bárta, Jan ; Vítek, Ondřej (referee) ; Ondrůšek, Čestmír (advisor)
This theses is related to design of synchronous reluctance motors of the transverse-laminated type. The first part describes synchronous reluctance machine via space-vector theory. Furthermore this part briefly discuss the main design aspects of synchronous reluctance machines. The main part of this thesis is related to practical electromagnetic rotor design for synchronous reluctance machine by means of finite element method. On this base the rotor has been fabricated and placed inside of induction motor instead of his original rotor. On this prototype was made several measurements which were compared with results from finite element method analysis. The last part of this theses is related to short study of synchronous reluctance machine dynamical behaviour under scalar and vector control.

Modeling of Exhaust Manifold for Turbocharged Engine
 Fanta, Tomáš ; Beran, Martin (referee) ; Svída, David (advisor)
This work describes different structural designs of the exhaust manifold and creation of parametric models of exhaust downpipes of supercharged engine 1,4 TSI. Next, the study deals with exhaust manifold’s materials and with present basic principles of thermodynamic and hydrodynamic. Then two parametric models were modelled in Solidworks software. First model was made according to existing exhaust manifold of engine 1,4 TSI. It was symmetrical model (collector in the axis). For second parametric model the collector was moved in horizontal direction, so this model is asymmetrical. Both models were evaluated considering their complexity of structural design and their manufacturing claims. Finally the possibility of CFD analysis for evaluation of parametric models was studied.
