Non-contact methods have been implemented in conjunction with levitation techniques to carry out the measurement of the macroscopic properties of liquids significantly cookxl below their nominal melting point. Free suspension of tile sample and remote methods allow the deep excursion into the metastable liquid state and the determination of its thermophysical properties. We used this approach t...

In this paper a new method is proposed for determining PID controller parameters in order to decrease losses in levitation system of magnetic trains. It is assumed that this system is a hybrid system and it consists of electric and permanent magnet. For optimization of losses initially AC losses of magnetic levitation system are calculated. Linear model of levitation system as well as modeling ...
