Opis:: We study optimal layout of piece-wise periodic structures of linearly elastic materials. The effective tensors of these structures are constant within pre-specified regions, the optimality is understood as the minimum of complementary energy. The suggested formulation leads to a construction that is stable under variation of the loading and which does not degenerates into checkerboard type structures. We derive necessary conditions of optimality of such layouts and analyse them. Numerically, we fins optimal structures for a number of examples, which are analyzed.

Opis:: This paper presents a new artificial neural network approach based on loss separation model to compute power loss on different types of electrical steels. The network was trained by a Levenberg-Marquardt algorithm. The results obtained by using the proposed model were compared with a commonly used conventional model. The comparison has shown that the neural network model is in good agreement with experimental data with respect to the conventional model.

Opis:: We have synthesized $Ba_{1-x}La_{x}Fe_{12}O_{19}$ (0 ≤ x ≤ 0.4) and $BaFe_{12-y}Nd_{y}O_{19}$ (0 ≤ y ≤ 4) samples in ammonium nitrate melt and nitric acid. The effects of La and Nd doping on the microstructure and magnetic properties of $BaFe_{12}O_{19}$ were investigated. The highest coercive field was obtained for the sample having La content, x = 0.3.

Opis:: $Fe_{36}Co_{36}B_{19.2}Si_{4.8}Mo_2W_2$ amorphous thin films have been produced by thermionic vacuum arc with thickness varying from 200 nm to 260 nm. X-ray diffraction has been employed to reveal a predominant amorphous phase in the as-prepared samples, although a small crystalline fraction cannot be excluded. The bulk magnetic properties of thin films were examined at room temperature using an ADE Magnetics EV9 vibrating sample magnetometer with maximum magnetic field strength of 1750 kA/m, real-time field control and dynamic gauss range capable of reaching a resolution of 0.08 A/m at low fields. The minimum value of the coercivity for the as-prepared samples was about 7 kA/m.

Opis:: A model based on artificial neural network was designed for the simulation and estimation of glass forming ability parameters and saturation magnetization and coercivity of bulk glassy alloys. Its performance is evaluated by the influences of different kinds of alloys and elements on the glass forming ability and magnetic properties. The values of glass forming ability parameters and saturation magnetization and coercivity values estimated by artificial neural network agree well with the experimental values, indicating that the model is reliable and adequate.

Opis:: In this research, the electrodeposition technique was employed to prepare fine-grained nickel, iron and iron-cobalt coatings with 1 μm thicknesses on the substrate of the $Fe_{36}Co_{36}B_{19.2}Si_{4.8}Mo_3W_1$ amorphous ribbons. The coating effect on magnetic properties was examined at room temperature using an ADE Magnetics EV9 vibrating sample magnetometer with maximum magnetic field strength of 1750 kA/m. It is found that Ni, Fe, and Fe-Co coated amorphous ribbons show 0.60, 0.71, and 1.01 T saturation magnetization, respectively, while uncoated ribbon has 1.55 T.
