This paper presents a new neuroimmune-based method for block recognition of railway rolling stock inventory numbers. The advantage of such approach is  classification without using of negative samples. Developed technique combines segmentation and classification that allows to achieve higher noise robustness, segmentation possibility of fuzzy combined digits which have different fonts and typeface, and invariance of existing numbers to scale changes. Proposed method allows to constantly increase the training set for the improvement in classification accuracy by new committee classifiers statistics due to the data reduction property achieved by using the immune clustering mechanism. Research results were implemented in the software system of automatic recognition of cars numbers (ARNV), which is operated on the JSC Russian Railways.

Keywords: Method for letters block recognition, the committee neuroimmune classification model, identification, automatic recognition car number, duplicate number

Problem research of display the orthogonal projection of four dimensional hypersurface defined by the equation in an implicit form one and two hyperplane. To communicate and bypass hypersurface Discriminants assumes that the hypersurface of the two-parameter family of two-dimensional display received surfaces in five-dimensional space. The analysis of kriminant four dimensional hypersurface orthogonal projection onto the coordinate hyperplane in two coordinate axes. The intersection of three dimensional hypersurfaces axiom (kriminant) defines a two-dimensional surface that is the envelope of the two-parameter family of two-dimensional surfaces. Are the necessary and sufficient conditions of existence of this envelope.
The results obtained are used to study the Discriminants four-dimensional hypersurface, the display of two-parameter family of spheres in a five-dimensional space.

Currently, more than 80% of water conveyance structures worked much the normative life. At the same time there is a simultaneous increase in the load on the aging waterworks, in the absence of the necessary skilled personnel and technical repair base will inevitably lead to an increase in the number of accidents due to operational reasons. Identification of factors that influence the condition of the facilities at the intersections , the search for methods of calculation and control of non-destructive methods to evaluate their work , life extension , etc. is of paramount importance at this stage. Residual life for the safe operation of water conveyance structures determined on the basis of system analysis with the development of the block diagram of a dynamic system having a number of subsystems. The main property that determines the life of the system , is the reliability of its elements , ie reliability and trouble-free operation for a certain period of operation. Dependability and reliability of the system as a whole is determined by the condition that each element of the system can be in one of two states - serviceable or failure.

The combination of the unique, abnormal properties shown by oxidic systems with structure of spinel on the basis of transitional elements chromites draws attention of researchers for many years. Some systems on the basis of transitional elements chromites (for example, nickel and copper chromites) have critical elements (multicritical points, lines of phase transitions of the second sort, etc.) on the phase chart. Near these elements of the phase chart materials possess unique chemical and physical properties. Therefore development methods of receiving and research of phase forming and properties in NIO-CoO-CuO-Cr2O3 system represent fundamental and practical interest for chemistry and technology of inorganic substances. In this work processes of spinel structure formation in system 0,6 NiCr2O4 – 0,2 CoCr2O4 – 0,2 CuCr2O4 from crystal chemistry positions are considered. Formation of two solid solutions on the basis of nickel (II) chromite – with structure of cubic spinel and with tetragonal distorted structure is established. The influence of cooperative Yahn-Teller effect on processes of a spinel forming and on stabilizing impact of chloride of potassium on process of education of  two spinel solid solutions is suggested. Influence of a power factor of cation stabilization in knots of a crystal lattice as one of the important factor in reaction of spinel structure formation is considered.
