The article is devoted to solving the urgent task, which is improving the accuracy of transient simulation modes of power supply systems of sugar factories. The material of the article is exploratory in nature, manifested in the fact that we have studied various mathematical models designed for the analysis of symmetric modes of deep bar induction motors. A number of the provisions of article have scientific novelty, which lies in the approach to the choice of the coordinate system for modeling deep bar induction motors. We have formulated the requirements for transient analysis method for deep bar induction motor. We have developed the mathematical models of high-voltage induction motors in different coordinate systems for the analysis of steady-state and transient modes of operation. Based on double-circuit rotor model of induction motor, an analytical expression for the frequency characteristic of the deep bar induction motor is obtained. As an example, we have calculated and presented real and imaginary parts of the frequency characteristic of the induction motor type 2АЗМ-2000 with slip s = 1. The mathematical models of induction motors allow using mathematical apparatus more efficiently to explore different symmetrical modes of engines. The study proposed to use transients in the power supply systems of sugar factories for the analysis. The authors suggest an approach to modeling, which can also be useful for modeling induction generators
In the article, we have considered the application of a system-cognitive analysis and the Eidos-X++ intellec-tual system to create complex multifactor models of nonlinear control objects on the basis of noisy frag-mented empirical data of large dimension and for the use of these models to solve problems of forecasting, executive decision making and research of the model objects. We have formulated the systematic generalization of the principle of Ashby (for nonlinear systems). The numerical example of a study of an abstract nonlinear system (Lissajous figures), in which the combined effect of multiple factors is the sum of the influences of each of these factors separately, that says about non-compliance of these factors, the principle of superposition and nonlinear effects in the system under consideration. It is shown, that the proposed device and software tools allow us to model such systems. We note, that the proposed device and instrumentation allow to interpret some classification scale, as projected geographical coordinates of the event, and others, like the foreseeable events and their severity, which allows you to get cartographic visualization of recognition of the place and time of events
The article presents innovative models and methods to diagnose the researcher’s synergic interaction with the scientific community (social mega-environment). It is known that the researcher’s interaction with the social mega-environment has two main directions: scientific collaboration and using the scientific community’s social and cultural potential; the former appears as scientific publications, while the latter appears as scientific citations. It is also known that synergic interaction is the interaction leading to the increase in activity results (according to the “1+1>2” scheme). In the article, the researcher’s synergic interaction is understood as his/her collaboration-based research activity that leads to obtaining the results impossible without this interaction. The theoretical significance of the research results is in the possibility for the further development of the sociology of science, as well as for the further development of the models of the individual’s interaction with the social environment; the practical significance is in the possibility to analyze the factors contributing to the success in the research activity of academic researchers and research teams (i.e. applicable for monitoring the research activity)
The article presents the criteria for the effectiveness of
the scientific and pedagogical workers of higher skill
levels for the preparation of scientific and pedagogical
staff. It is known that the preparation of the teaching
staff (PhDs) - one of the most important activities of
higher education institutions; Moreover, when the state
accreditation of higher education institutions
compulsorily taken into account indicators that reflect
the impact of training candidates. Also, of course, that the training of the teaching staff (PhDs) - activities that
require both high levels of research and pedagogical
competence. This means that the results of scientific and
teaching staff higher qualification levels for the
preparation of the scientific staff - both indicators of
research and pedagogical competence; own training of
researchers - an area of "crossing" of scientific and
pedagogical activity. Unfortunately, the increase in the
number of scientific personnel being prepared does not
always mean quality growth. Often trained scientific
personnel (PhD) not only do not approach the level of
competence of its research (the results of research) to
the supervisor, and stopped to engage in scientific
activities after defending his doctoral dissertation (or
engaged at a low level). Therefore, the article authors
consider it expedient to propose indicators that reflect
not only the amount and timeliness of the research
training (PhD thesis defense sometimes occur many
years after graduate school), but also the productivity of
this activity. From the point of view of the authors, the
success of research training only can be considered
productive when prepared by the scientific supervisor
candidates of sciences are highly qualified scientific
personnel, ie conduct high-level research, the results of
which are recognized by the scientific community; the
same is true of the scientific advice (highly qualified
scientific workers - doctors). The practical significance
of the study results - in the possibility of objective
monitoring of research activity of scientific-pedagogical
personnel of higher qualification. Methodological bases
of research: a systematic, competence, sociological, and
metasystem qualimetric approaches. Methods:
modeling, methods of quality control, methods of set
theory, relations and graphs. Normative base of
research: the Federal Law "On Education" (2012), the
federal state educational standards of higher education
(2014, 2015). The work was performed as part of
research projects "Monitoring of the research activities
of educational institutions in the information society"
(№ 16-03-00382) and "Modern information and
educational environment" (16-36-00048) with the
financial support of the Russian Humanitarian
Foundation from 17.03. 2016.
The article studies the works of the theorists of postindustrial
and information concepts of the society’s
development. The author thoroughly examines the role
of these paradigms in shaping perceptions of the
modern socio-cultural space. He notes the high
prognostic value of the studies for understanding the
phenomenon of the Network society. The author draws
attention to the fact that they cannot fully describe the
current state of social space and do not have the
required methodological diversity. It is noted that new
ways of thinking and organizing objects of the virtual
environment are required. According to the author, it is
important to designate the information as one of the
priority components of the transformation process in
society. Technology and the Internet mediated
communication creates a new type of social relations,
switching attention to the creation of social
communications as a play environment of interactions.
Compression of the space-time continuum described in
terms of information and global social space
redirection, helps to comprehend the locality, mosaic
and fragmentation of the occurring type of sociality.
This phenomenon appears due to the involvement of
individuals in the total communication system that
turns out to be the cultural manipulation, affecting the
needs and behavior in all spheres of life, as the
information acquires the ability to program. Internet
creates the illusion of fullness of socially demanded
actions and expectations. The article shows that the
interest in the phenomenon of image reality is
increasingly growing among the social thinkers, who
see it as the future state of the social space. The author
draws attention to the fact that the development of the
online world is defined by the main task of the modern
human sciences, the solution of which is carried out by
the ordering and value ranging the virtualization
phenomena, by the optimization of methods of control
over the interaction of real and virtual realities
The known models of the city from a position of
knowledge economy are analyzed in the article. The
hypothesis of the research shows that practice of a
strategizing of the city has to be based on polymodel
approach when several key models adequate to modern
trends are taken as a basis, connected with formation
of sector of economy as a part of regional social and
economic system, and other models are addition and
essential extension of the contents chosen basic
models, strengthening their cognitive component.
Research of the model of a creative city, creative
clusters, quarters and zones of the city, model of the
digital city, model of an eco-city is conducted.
Substantial features of models are revealed. It is
established that the informative potential of types of
models of the city increases on the basis of research
and identification of mechanisms of mutually
transition (participation) of elements of one model as
elements another (others) complementary models. The
city as the semistructured system consisting of diverse
subsystems and elements does not submit to rational
planning owing to structural and territorial duplication
of functions and asynchrony in functioning and
changes, and also owing to the history and sociocultural
specifics of the population significantly giving
immanent logic of life. It is necessary to create flexible
system of the city strategy on a polymodel
(interdisciplinary) basis, based on activization of
growth sources, various on contents, for the purpose of
formation of new image of the cities
