The worst-case model of high-frequency electromagnetic wave diffraction by circular or rectangular apertures in a conducting screen is proposed. The model is based on the worst-case generalization of analytical solutions of diffraction problem. These solutions were obtained in the frame of approach based on the theory of Hertzian vector. In order to develop the worst-case model, the envelope of the field maxima is found. The results obtained by the model correspond to the results of numerical simulation. Proposed model can be used for calculations of EMC due to high computational efficiency and worst-case character.

A method to predict the reliability of software is introduced in this paper. The method is based on the calculation of correlation between reliability measures and software errors. The dependency between errors and reliability is defined by calculating Pearson correlation ratio, which is used further to build the identity matrix to match error groups and reliability measures. Input for this calculation is well defined and explained including the direction of the correlation and confidence level. This paper also proposes the way to integrate the introduced method into agile software development process.

Monocrystalline ZnO plane have been implanted by high dose (1,5·10¹⁷ cm^-2) ions of manganese, iron, cobalt, nickel with energy of 40 keV at ion current density of 4 mA/cm² in order to modified magnetic properties. Magnetic hysteresis loops at T = 5 K, temperature dependence of magnetization at sample cooling without and in magnetic field 2 mT in the temperature range 5-300 K were investigated. The main magnetic characteristics such as coercive force, magnetization saturation and residual magnetization have been estimated. It has been also shown, that implantation of cobalt and nickel ions leads to ensemble of Langeven magnetic nanoparticles formation in zinc oxide.
