Studies of social stereotypes and stereotyping mechanisms as part of the process of social cognition occupy priority places in the research of images of interacting partners. The problems of accentuation stereotypes in real behavior and activity of individuals in the field of road traffic (drivers, pedestrians, representatives of DPS) today only acquire some shape, but has not yet been properly addressed to. Traditional studies of gender stereotypes, unfortunately, are not able to uncover the underlying mechanisms of perception, which "create and run" the process of stereotyping due to specific reasons, objectively contained in the activity of subjects of interactions on the road. Attempts to detect and describe these mechanisms require research of real interactions of the subjects and objects of stereotypes, namely those and their specific characteristics that contribute to the emergence and actualization of gender stereotypes. The importance of this article is determined not only by the prospects of the development of theories of stereotypes as forms of everyday consciousness, but also the possibility of using some of the ideas for positive change of life of road users, accompanied by a high level of conflict, risk, interaction and challenges related to different factors of social reality. Gender stereotyping of subjects of road interactions are important factor clearly uncommitted to objective rules and norms of the culture of behavior on the road.

The methods of the diagnostics and oil-and-gas installations state analysis reliability increasing based on usage of the parametric methods of statistics are discussed in this paper. The variance analysis of the mechanical properties of the pump rods made of normalized steel is given in this paper (according to the data of the manufacturing plant for the period of 10 years). It is found that breaking point and yield stress are distributed with the truncated normal laws in the region of minimum values. The obtained average values and variation coefficients of the mechanical properties within the steel grade permit to calculate the statistically significant changes of the mechanical characteristics. The correlations between Vickers hardness and breaking point (Vickers hardness and yield stress) in the case of steels produced in the Russian Federation for the pressure-operated vessels are also presented in this paper. These correlations permit to determine the strength characteristics with the relative error of 12% according to the hardness value. In the case of transferring the obtained correlations on the steels produced in Japan the systematic underestimation of the yield stress is 0,85 fold with respect to the value given in the certificate. The factors that influence on the microanalysis sensitivity and accuracy are revealed, the optimal scanning electron microscope mode and research conditions for the chosen patterns are also determined. Evaluation of the systematic inaccuracy of determining the carbon content in the steel is obtained in this paper. It is found that the measurement error for the scan area from 3 x 3 to 20 x 20 mm and accelerating voltage from 10 to 15 kv is minimal. The usage of the obtained results permits to increase the validity of the findings in the diagnosed installations condition evaluation and determining the conditions of their further exploitation.

It is shown that the current direction of the development of electronic document management is the transition to the information systems that support the dialog interaction with the user in natural language. This area is challenging because of exponential growth of data processed by modern information systems. Described the problem of converting verbal criteria describing properties of the required data, SQL queries, implementation of which will allow to obtain the required data. As a practical example, the selected task is the classification of employees in three clearly defined categories: ""small experience"", ""average experience"", ""great experience"". Before you create a database assumptions were adopted: the experience of employees is taken into account from 0-25 years. The time period to 7 years is an indicator of employees with low seniority. As close to a group of employees with secondary seniority are those who have work experience of 8 to 13 years; a great experience – more than 15 years. Create table ""Employees"", consisting of the following fields: id, name, Sex, Phone, notes, date of hiring, date of dismissal, work Experience in similar position, Experience just. The work deals with the queries to retrieve data based on the SELECT statement of the SQL language. Mathematically formalizing verbal filter criteria data was formalized with trapezoidal membership functions. Describes the implementation of the conversion process trapezoidal membership functions in SQL queries against a relational database. Implemented conversion mathematically consistent as the theory of fuzzy sets and the concept of relational databases (i.e. SQL standard). Compliance transformation of fuzzy set theory in the future will allow the use of operators for manipulating sets (Union, intersection, etc.), and compliance with SQL to practically implement the proposed approach by means of a broad class of relational database management systems.

In this paper, we consider the problem of development of equivalent circuit of non-linear element with the current-voltage characteristic controlled either voltage or current, which can be modeled without any changes of scheme in accordance with design requirements. For solving the problem we use an analog-digital-analog element. The current-voltage characteristic of this element is determined by the program of the digital device work. To approximate the characteristics of non-linear elements we apply polynomials of varying degrees - segments of the Taylor series, Maclaurin, Lagrange, et al. In our opinion, the solution of such a problem is relevant.

Studies of gender and family dynamics in society are of great interest for foreign and domestic scientific communities. The results of studying the trends in these areas from the point of view of the students about the "ideal behaviour" of modern men and women are very important, as the social group of young people has always been and is a specific indicator of the state of the society. Today, the availability of various models of the behavior of the sexes is significantly determined by the media. However, new, variable "patterns of behavior" in society does not mean denial of traditional patterns of conduct of men and women. Despite some "westernization" of the young Russians, the national gender factor "works" thereby consolidating society and preserving the national identity of individuals.
