The paper discusses methods for determining the frequency of maintenance (MOT). The proposed method allows to simulate the technical condition of the vehicle under various conditions and modes of its movement, taking into account the random nature of the changes of various factors. The proposed method takes into account the probability of failure for a given range of the vehicle (TC), as a generalized description of the technical condition of the car, indirectly affect most of its domestic individual characteristics and external destabilizing factors. The novelty of the method lies in the fact that takes into account not only the standard run, and an optimum set of operations in a particular embodiment, service and repair. To allow for individual TC correction coefficients of standards periodicity TO calculated using fuzzy logic.

The article gives a statistical analysis of women's involvement in scientific research activities, identified the main trends of women's scientific and educational activity. On the basis of statistical array available on the website of Sciences, conducted a gender analysis of the academicians and corresponding members of the Academy of Sciences in quantitative terms and in the spheres of science. Based on the analysis indicated the main factors influencing participation of women in science, the key ones are: the fall of prestige of the profession of the scientist; the wage gap between men and women having equal data; the predominance of women in teaching positions; the phenomenon of the "glass ceiling".

This paper proposes a new approach to railway vehicles localization based on image processing method consists in the recognition of the railway car coupler on the graphical images obtained by cameras of versatile automatic recognition system for railway cars’ numbers (versatile ARS-RCN system). A model based on the recognition of the coupling of the real-valued negative selection algorithm with variable-sized detectors was developed. Computational experiments that showed the effectiveness of developed model in comparison with the classical support vector machine on real data collected on one the versatile ARS-RCN system object were performed. The effectiveness of the proposed approach in the duplicated mode (using two cameras) and in combination with the basic method of localization of mobile units on the basis of inductive sensors passing wheels was showed.
