The quantum and chemical simulation (HF/MP2, cc-pVDZ basis) of diphenyl-2,2',4,4'-tetraamine (DPTA) molecule properties allows to determine the its thin film pyroelectric properties since hydrogen bonds between molecules in the film are weaker than intramolecular bonds. The study of a DPTA photosensitive pyroelectric film microstructure enables one to assume that the dipole moment of the needle-shaped crystallines densely stacked and extended along a film surface is aligned perpendicularly to the surface. The possibility of the reproduced control for DPTA properties may be used when producing the most effective pyroelectric film for photodetectors in infrared wavelength range.

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

Questions of an engineering and psychological assessment of the equipment of the enterprises of the motor transport at a design stage on the basis of the algorithmic description of activity of operators are considered. It is shown that on in the analysis of algorithms at a design stage it is expedient to use the device of fuzzy logic.

The method of application of fuzzy logic to solve the problem of spatial planning using geographic and information systems is described. The spatial arrangement of objects on the map is used as input factors of the solution, to find which a model of the spatial descriptions of objects using a bitmap representation is constructed. The way of formalizing fuzzy judgments about positional relationship of objects and the system of inference making based on the fuzzy logic methods is developed. An example of using the method described in this article to determine the sanitary protection zone of industrial waste landfill in the territory of the Republic of Bashkortostan is given

Keywords: fuzzy logic, geographic information systems, the problem of territorial planning, disposal of industrial waste, protection zones

Disassembling of NPP equipment, systems and metal constructions is a compulsory procedure in the final stage of NPPs work cycle, namely withdrawal. Disassembling technology is closely linked with some necessary conditions, that is why some mandatory requirements must be fulfilled.
The disassembling tasks can be carried out with the help of modern tech-nologies, means and instrumentware. The system of task-oriented engineering and adaptation to the environment and its conditions provides informational and me-thodical supporting in the process of developing the technology of equipment dis-assembling.   
This article presents the common methods and practical recommendations for developing the technological process of disassembling of NPP equipment.
