Opis:
Usage of the distributed information databases (DIDB) is the most spread way of allocation of service of clients and support of cooperation between large corporations or banks. At usage DIDB in real-time mode (the actual data are accessible to all valid users at the moment of inquiry to reading or upgrade) most essential is the factor of capacity of networks. Change of the physical characteristics of modern networks is very expensive procedure. Moreover, if a gorge by transmission becomes data links, their replacement also requires essential time, that can reduce in the additional losses. In such conditions the mechanism of backup is applied to support of continuity of the computing process (CP). Except for data links a gorge in operation with DIDB can be intermediate sites, gateway servers, routers and other equipment. Frequently these functions can fulfil the same computational capabilities, which are used for processing DIDB. In this case (if the backup is not stipulated by network architecture) it is necessary to reallocate a working load (WL) between other network nodes on time of exception of a site for realization of adaptive operations or its replacement.

Opis:
The corrosion action for bulk and thin Nd₂Fe₁₄B films magnets in different corrosion media was studied. The thin Nd-Fe-B films of 100 nm ≤ d ≤ 1000 nm were deposited on glass substrate by "flash" evaporation method. The structure and microstructure of the samples were studied by X-ray diffraction analysis, scanning electron microscopy. The temperature dependence of the magnetization before and after corrosion action was carried out by ponderomotive method in the temperature range 80 ≤ T ≤ 800 K. It is shown that the specific magnetizations of the thin Nd-Fe-B films with d ≥ 1000 nm are comparable to those measured for the powder samples. The values of the coercive and saturation fields were determined from the hysteresis loops measurements.

Opis:
The synthesis of polycrystalline $Mn_{1-x}Gd_{x}Se$ solid solutions is carried out by solid state reaction method followed by quenching from the temperature of 1370 K. The X-ray diffraction studies realized at 300 K revealed that the structure of the single phase samples in the 0 < x < 0.15 concentration range is identified on base a face centered cubic crystal cell of Fm3m space group. The heating of the solid solutions to 900 K does not affect on the magnetic susceptibility as the dependences is identical to the measurements in the "heating-cooling" regime. Comparing the research results of magnetic properties of the $Mn_{1-x}Gd_{x}Se$ solid solutions with those of $Mn_{1-x}Gd_{x}S$ solid solutions, we can conclude that substitution of manganese ions by gadolinium in manganese selenide lead to more changes in the basic magnetic characteristics than in manganese sulfide.
