The objective need to improve information security systems in the conditions of information-telecommunication technologies developing is shown. A new area of NP-complete promplems of diophantine analisys is firstly researched, namely Tarry–Escott multigrade diophantine equation systems (MDES) of given dimension and degree. The theorems, that describe parametrical MDES parametric solution properties, required for the development of the algorythm of building of dissymmetric bigram cryptosystem, are given in the article. The author's theorem, which allows to develop information protection system (IPS) mathematical model as a cortege, containing diophantine probleme. A new approach to develop dissymmetric bigram cryptosystem(DBC) on the base of two-parametrical MDES solution, which generalize open key cryptosystem, is considered. Forward and reverse conversions based on parametrical solution are suggested tyo realize on such algorythm. A new concept of equivalence of ordered sets of numbers (parameters) of a given dimension and order is introduced to build DBC mathematical model, using two-parametrical MDES solution. Described mathematical model demonstrates application potential of diophantine equations for IPS with a high degree of reliability.

Automation of agriculture is currently a promising and actively developing branch of robotics. At the moment, there are many foreign analogues offering ready-made solutions for automatic control of sowing crops. However, in Russia, most of the sowing is carried out on mechanized plants under the mandatory supervision of a highly qualified specialist in the maintenance of the plant.

Research of models of formation of integration projects on the basis of points of growth reveals a number of important aspects related to the stages and management of their implementation. The focus on the formation and support of growth points essentially excludes the use of unary models in the planning and implementation of projects within the framework of national programs. In order to overcome the limitations imposed by this type of project, various integrative mechanisms are proposed. The peculiarity of the considered binary models describing the integration mechanisms is the preservation of the basic cycle of the project points of growth within the national program. However, the introduction of additional contours in the model with growth accelerators, with related or integrated projects, as well as attracted resources can reduce the risks caused by high rates of development and innovation issues. The integration potential of the binary model with the project of the growth point in the basic circuit generates a dynamic competitive advantage, i.e. a sustainable, increasing advantage over time that is not related to the amount of initial funding. This advantage generates a powerful growth cycle that can provide a significant increase in profitability over a long period of time. The integrative nature of growth point projects should be envisaged already at the planning stage of national programmes with appropriate monitoring and funding instruments.

The complete cycle of flat axisymmetrical problem solving is given in this paper: from getting the main resolving equation to solving the practical problem of polymeric tube creepage. Two non-linear laws of “stress-deformation” union are used: Maxwell-Gurevich law and Maxwell-Tomson law. Camparison and analysis of the obtained data are given, as in some cases it is enough to use Maxwell-Tomson equation than to use more complex Maxwell-Gurevich union equation. Solving of the problem is given with the use of numerical method – finite difference method. In the case of the temperature field, all physical-mechanical parameters of the material (elastic and relaxation) are taken as the temperature function. Thees, the non-uniformity of the material is considered. To determine the temperature field Furje heat transfer equation is used.

The article presents basic equations for reinforced concrete elements that are experiencing bending moment and axial force, taking into account the creep of concrete. The stress-strain state of reinforced concrete statically determinate three–hinged arch is investigated on the basis of these equations. Also for this task we gained the resolving equations of finite element method and compared the numerical-analytical calculation with the numerical performed using the finite element method to the arch loaded with a uniformly distributed load and having the shape of a circular arc. The calculations used viscoelastic model, according to which the total deformation is the sum of concrete elastic deformation and creep. We consider a rectangular cross section with symmetrical reinforcement. It is shown that because of creep stress redistribution between concrete and reinforcement arises.
