- Acoustic holography in diagnostic of passenger cars
High level of noise usually means bad design or malfunction of the machine. It is induced by undesirable vibrations of the machine. In lot of cases, there is impossible to identify cause of the noise in full operation of the machine. It is possible to localize noise sources, analyse core of the problem and adjust design by application of the acoustic mapping methods. Main goal is application of the acoustic holography for diagnostic of the noise sources in passenger cars. It is mainly experimental work with aim on imagination of acoustic properties of the object in 3D based on measurement of acoustic pressure levels.

- Design of structured magnetic circuits
The utility value of electromagnetic machines is dependent on construction and material of magnetic circuit. The most limiting factors are the highest achievable magnetic flux in the magnetic circuit and generated eddy-currents. Eddy-currents can be almost eliminated by the use of ferrite or SMC materials with high electric resistivity. The relative permeability and the level of magnetic saturation is low in comparison with metals (steel, iron, cobalt alloys etc.), which reduces the power of the machine. 3D print of metal materials brings new possibilities in magnetic circuit design. Smart structure of magnetic circuit made of metal enables to achieve high magnetic flux and in the same time to secure low level of generated eddy-currents. Main goal of this work is a design of smart structures of the magnetic circuits. It is mainly experimental work, which should utilize 3D printed structures of the circuits to achieve its excellent magnetic properties, low weight and low losses due eddy currents.
