The article examines the cognitive and behavioral components of group attitudes toward political order of students of DGTU.  Pilot study took place in 2013 and was carried out using questionnaires, which was attended by 52 people. The analysis represents a hierarchical clustering on the basis of consecutive factorization. It is received, group level of a relative deprivation – 0,46. In assessing deprivation group decomposed into two subgroups, with average values in each - 0.3 and 0.6. Perceptions of political order at the cognitive level:  -0,174 for local government and-0,139 for Russia. In perception of local government the group broke into two subgroups: -0,3 and 0,2. Behavioral component perception of political order defined by two subfactor: active behavioral level - 0.39, and the estimated level of oppositional behavior - 0.57.

In the autumn of 2013 a pilot survey was conducted among students DSTU, which was attended by 52 respondents. Purpose - to reveal emotional perception of the students of local and central political government by the method of semantic differential. The paper presents a psychosemantic phenomenological model processing of survey results by the method of semantic differential. On average semantic portraits are calculated relative distances between the group images of real political order and the images of the ideal constructs. Phenomenological parameters are determined by them and calculated the required level of group emotional perception of a political order. Calculations group levels of emotional perception of the political order showed similar results as the linear approximation: -0.015 for Region and for Russia as a whole -0.033. Shown, the model allows to determine not only the group levels of perception, but also to build the surface of the stationary states. This surface describes the behavior the level of perception associated with a quasistatic change of phenomenological parameters caused by external conditions. Images of perception of real political orders are in quiet area. At quasistatic variations of external conditions it is necessary to expect little smooth changes of level of perception.

Modern CAD systems now allow automate most of the stages of design and technological preparation of production . But there is a number of routine procedures. This article is about the details classification operation analysys .
 A review of existing solutions has shown that there are two ways to classify the details. The first - a “manual” characteristics of the classifier, assignment. This is the major method. The second is the expert system "Klassifikator" from the AsconCo., which is based only on the verbal description of the parts and the user selected one of parts from the existing. So that the function of user is to provide the recognition of images patterns.  These methods of pattern recognition  systems are successfully solve complex image recognition task . Analysis of methods of recognition led to the selection of the neural network method for classification of items.
We want you to use expert system consists of a Hamming neural network emulator and the semantic model of knowledge representation with direct output to solve the problem of classification of parts.
This combination of neuro-cybernetics and information approach to the creation of an expert system can either automatically determine a part characteristic by its image , or in a semi-automatic mode, prompting the missing information from user.

This paper outlines the implementation of computer model of second-order visual mechanisms that are specific to spatial contrast modulations, and represents the results of testing the model. Computer simulation is based on "Filter-Rectify-Filter" model with some important additions. The inhibitory parts of receptive field of simulated mechanism are non-selective to orientation and spatial frequency of texture elements. Texture modulated by orientation or spatial frequency does not reduce flank inhibition and does not activate the mechanism. Unmodulated texture  also does not cause activation of the filter because the flanking inhibition will be equal to or exceed the excitation. However, increasing the contrast in the center and reduction it on the flanks leads to the activation of the second order mechanism.
