Method of successive approximations was used to solve the problem of optimization of multispan continuous beam. Cross section of a beam was a welded I-beam.  By the variation of the width of the shelf we ensured that the maximum equivalent stress for energy theory of strength in each section is the same throughout. The solution is made numerically using complex MatLab. Bearing capacity of beams with variable stiffness along the length increased in 2 times in comparison with the beam with constant stiffness and the same mass. The proposed method can be applied to frames, taking into account the contribution of longitudinal forces in the equal stresses. Another effective way to change stiffness is to change the height of the wall of I-beam. In practice curvilinear shape of beams or shelves are not used because of complexity of manufacturing. They are replaced by the discrete form of cross section.

In this paper, a new simple and accurate hybrid table/analytical model of the MOSFET drain current based on the interpolation of table parameters is proposed. This new hybrid table model has an accuracy similar to the pure table models but requires no complex parameter extraction. The drain current in the hybrid model is calculated as the product of the analytical model current and the correction factor approximated by two-dimensional series.

Briefly discussed the theoretical model of the spectrum of RR intervals and its changes depending on the processes taking place. Made a device for measuring cardiointervalogramms (CIG). Obtained from the renting of data, of varying duration and frequency shall be recorded for further processing. The analysis revealed that the resulting spectrum satisfies the conditions considered in the theoretical model, and can be further analyzed with fractal characteristics. Such an analysis is of great importance in the diagnosis of the patient directly to the duration of the therapeutic procedure for the optimization of both time and intensity exerted influence.

In article the new model of interaction of functional systems of various hierarchical levels is offered: from unicell level, to level over social objects. Feature of model is introduction in its structure: perception filters, the accounting of a strong-willed component, convenience of its application not only in the field of physiology, but also in sociology, psychology, value logy and other sciences describing behavior of reasonable objects. The analysis of signals carrying out exchange of information between functional systems of different level of hierarchy is carried out. The offered model allows explaining and predicting many psycho physiological patterns accompanying conditions of expanded consciousness, and arising at activation of reserve possibilities of the person.

The research of the proluvial and eluvial-diluvial loess-like loams with wide distribution in the Kuban plain was conducted. In this work the properties of the collapsible loess soils, which developed the processes that lead deformation of the engineering structures, violation of planning fields, to their water logging, etc, was considered. The analysis of subsidence processes, their origins and causes activation is provided. The link between subsidence and suffusion processes was conditioned. It is proved that the subsidence processes significantly affect the safety and population’s comfort living. The issues about the regime observations of these processes are raised.

"The concept of the nested metagraph as the model of a complex object with different levels of generalization is introduced. It is shown that the nested metagraphs reflect the general system concept for description of complex objects with synergistic effect. This approach enables moving from the set-theoretic description of complex objects to their algebraic-theoretic description, thus increasing the model adequacy to real-life objects. The application of the nested metagraphs, in particular to business-intelligence and semantic search is considered. "
