Verification of Berghausen noise method for residual stress measurement
Krejčí, Petr ; Návrat, Tomáš
This paper deals with verification of Barkhausen noise method for residual stress measurement. The aim is to verify functionality of commercial equipment which is using Barkhausen noise method for residual stress measurement by simple experiment. The experiment was realized by means of equipment for material testing with ability to load test sample by simple tension with known magnitude.
Design optimization of magnetic drive with permanent magents.
Krejčí, Petr ; Ondrůšek, Č.
This paper presents finite elements method (FEM) model of magnetic coupling for design optimization of inner part of magnetic coupling in order to increase the maximal torque. The genetic algorithm method in connection with FEM model of magnetic coupling was used for design optimization procedure.

Experimental and numerical analysis of magnetic drive
Houfek, Lubomír ; Fuis, Vladimír ; Krejčí, Petr
In paper is presented methods of numerical and experimental solution of magnetic drive.
Behaviour of magnetic drive for different number of magnetic pairs and temperatures
Houfek, Lubomír ; Fuis, Vladimír ; Krejčí, Petr
This paper concurs on our previous work in this problem. The mostly limited parameter for using magnetic drives is temperature. Permanent magnets can't use near Currie point, where it lost our magnetic features. Temperature changes under Currie point changes of magnetic properties of permanent magnets and changes of behavior of magnetic drives. The second main limited parameter is core pole factor. The magnitude of core pole factor relate with number of pairs of permanent magnet.

Návrh nového zařízení pro přípravu směsi za účelem měření nukleační rychlosti v systémech agresivních par s použitím rázové trubice
Krejčí, A. Petr ; Hrubý, Jan ; Haartsen, J.
Binary homogeneous nucleation of sulphuric acid-water droplets is traditionally considered as a model of secondary aerosol particle formation in the atmosphere.
Questions of Full Employment in Terms of German Economic Miracle
Krejčí, Petr ; Stellner, František (advisor) ; Jeřábková, Zdenka (referee)
The aim of the bachelor work is to analyze progress of economy in Federal Republic of Germany after Second World War. I will aim to point to causes and factors, which have had consequences to quick economy increase in Germany's destruction economy after war. Aside from analyze single steps, which have led to restart Germany economy the emphasis will be given on economic and political concept of socially market economy which was one of the main pillars of Germany economy miracle with emphasis on full employment problems.
