Psychological possibilities and functions of modern information technologies as the means for students’ self-realization in university training
The objective of this study was to define the leading functions of information and communication technologies that stimulate the manifestation of various forms of students’ self-realization in the educational process of the university. The socio-cultural approach that enables to reveal the role of information technologies as means for transferring the experience of culture and realizing students’ essential forces is the leading approach to study this issu
Pedagogical functions and potential of volunteering activities in social upbringing of student youth
This study aims to reveal the pedagogical resource of volunteering activities as an efficient form of students’ full-fledged socialization. It is based on the methodology of the activity and sociocultural approaches to psychological development of personalit

The article discusses the phenomenology and the conditions for the development of an innovative managerial style for lyceum managers in the Russian education syste
РАЗРАБОТКА НЕЧЕТКОЙ НЕЙРОННОЙ СЕТИ ДЛЯ ИНТЕРПРЕТАЦИИ РЕЗУЛЬТАТОВ АНАЛИЗА РАСТВОРЕННЫХ В МАСЛЕ ГАЗОВ
Purpose. The purpose of this paper is a diagnosis of power transformers on the basis of the results of the analysis of gases dissolved in oil. Methodology. To solve this problem a fuzzy neural network has been developed, tested and trained. Results. The analysis of neural network to recognize the possibility of developing defects at an early stage of their development, or growth of gas concentrations in the healthy transformers, made after the emergency actions on the part of electric networks is made. It has been established greatest difficulty in making a diagnosis on the criterion of the boundary gas concentrations, are the results of DGA obtained for the healthy transformers in which the concentration of gases dissolved in oil exceed their limit values, as well as defective transformers at an early stage development defects. The analysis showed that the accuracy of recognition of fuzzy neural networks has its limitations, which are determined by the peculiarities of the DGA method, used diagnostic features and the selected decision rule. Originality. Unlike similar studies in the training of the neural network, the membership functions of linguistic terms were chosen taking into account the functions gas concentrations density distribution transformers with various diagnoses, allowing to consider a particular gas content of oils that are typical of a leaky transformer, and the operating conditions of the equipment. Practical value. Developed fuzzy neural network allows to perform diagnostics of power transformers on the basis of the result of the analysis of gases dissolved in oil, with a high level of reliability.Разработана и обучена нечеткая нейронная сеть для интерпретации результатов хроматографического анализа растворенных в масле газов. Предложено определять функции принадлежности лингвистических термов с учетом функций плотностей распределения концентраций газов для трансформаторов с различным состоянием. Выполнено тестирование обученной сети на независимой выборке. Проанализированы возможности нейронных сетей распознавать развивающиеся дефекты на ранней стадии их развития, или рост концентраций газов в исправных трансформаторах, после аварийных воздействий со стороны электрических сетей
Attractive spheres of students’ self-realization as practices for supporting their psychological well-being in university education
The study is aimed at finding the varieties of appealing spheres for realization of students’ potential in higher school. The authors substantiate and develop the concept of attractors for students’ self-realization, which designate the appealing spheres and forms of manifestation of students’ personal efforts and capacities in higher educatio
Socio-cultural dominants of higher school innovation mission
The article deals with the value backgrounds to ensure the innovative potential of the Russian higher school. Based on the methodology of socio-cultural determination, the authors propose to apply largescale civilizational dimension for understanding the higher school's innovative missio
Axiological dimension of the higher school innovative potential
The article deals with the value backgrounds to ensure the innovative potential of the higher school. Based on the methodology of socio-cultural determination, the authors propose to apply large-scale axiological dimension for understanding the higher school's innovative mission. This dimension encompasses a number of central ideas in the history of the development of higher school within the bosom of major socio-cultural domains, such as: social-focused, theology-focused, anthropocentric, profession-focused, scientific-focused, ideology-focused and market-focuse
Time-reversal symmetry breaking by ac field: Effect of commensurability in the frequency domain
It is shown that the variance of the linear dc conductance fluctuations in an
open quantum dot under a high-frequency ac pumping depends significantly on the
spectral content of the ac field. For a sufficiently strong ac field the dc
conductance fluctuations are much stronger for the periodic pumping than in the
case of the noise ac field of the same intensity. The reduction factor r in a
static magnetic field takes the universal value of 2 only for the white-noise
pumping. In general r may deviate from 2 thus signalling on the time-reversal
symmetry breaking by the ac field. For the bi-harmonic ac field of the form
A(t)=A_{0} [cos(\omega_{1} t)+cos(\omega_{2} t)] we predict the enchancement of
effects of T-symmetry breaking at commensurate frequencies
\omega_{2}/\omega_{1}=P/Q. In the high-temperature limit there is also the
parity effect: the enchancement is only present if either P or Q is even.Comment: 8 pages, 6 figures, submitted for "Electronic Correlations: from
