Volume idea of spektras representation of append-type controllers
Bekasov L.S.
Abstract
The methods of sensitizing at distinction of structural modifications in multiple Systems, which are adduced by texts from four-letter Concatenations are proposed in this work. There are also introduced such ideas as "the index of saturation" and plane conception of texts into volume conception reformation. Using of these ideas in combination with the Fourier-method conception based on modify abutting orthogonal impulse functions allow to discriminate structural changes in appended texts of any complexity.

The paradigm of limited rationality of decision making
Vittikh V.A.
Abstract
The article gives a substantiation of the necessity to develop a paradigm of limited rationality of decision making in complex artificial (social, economical, socio-technical, etc.) systems, that are created and functioning with the participation of people. The reason to do it is that the conventional rationality coming from the cognition of reality "as it is", without taking into consideration the subjectivity of people, becomes inapplicable in this case. The basic principles of the limited rationality are given in the paper. They assume the application of the methods of humanities together with the natural science approach to research and the use of the oriental world-view characterized by the junction of man with the existence and by the emphasis of ordinary representation of existence instead of scientific representation.

Synthesis of heterogeneous self-organizing models for for plain structures approximation
Kolpashchikov S.A., Ryazanov A.S., Yudashkin А.А.
Abstract
A solution for a problem of a given heterogeneous structure approximation by an arbitrary dimensional elastic dynamical model in a plane is proposed. The model is developed on the as the potential system with the characteristics of the elastic loop with the connectivity matix and the self-organizing form with the state memory. It is shown that the proposed model is able to fit the given structure as the sub-optimal solution, preserving its form at least close to its initial or desired construction, while the dynamic structure parts interact with same type parts of the given structure only.

Use of the correlation method for averaging of chromatograms
Sayfullin R.T.
Abstract
We consider the receipt problem of chromatogram, which is averaged on some number of inputs. Estimation algorithm of the averaged chromatogram comes to solution of linear algebraic combined equations. By certain variants of input series' formation the information matrix turns into Tepliz's matrix, that simplifies its conversion. In correlation chromatography (CC) the injection is made according to random principle. Input actions, which may be used in CC, are tested.

Tishkovskaya Y.V.
Abstract
Two matrixes are considered, which allow to take a decomposition procedure for the works of geological recon troop to the particular stages. This simplifies the correlation determination procedure between factors, by virtue of the fact that real riscs are allways connected and reasonable. In result it becomes possible to perform a decomposition of works drocedure of a troop to different stages and formalize all the contradictions of aims of different departmens, which are in cooperation during theese works.

Abstract
The influence on the characteristics roughness and microhardness of high-cycle fatigue actions of the plane samples from the alloy EI698 VD, previously hardened in the rate of the air shot blasting, was researched. It became clear, that microhardness correlates with the value of the compressing remaining tensions at hardened case, but roughness doesn't depend on rates and character of fatigue actions.
