The article presents the criteria for evaluating the
integration of researchers in the scientific community,
based on an analysis of its citations. It is known, that
one of the major components of interscientific
communication (communication in the scientific
community) is a citation of scientific publications
(monographs, articles, etc.). According to the
sociological approach, a scientist is a part of society, ie,
scientific community; under scientific community we
understand scientific mega environment (opposed to
research groups of institutions and their structural units).
Integration of a researcher to the community has many
aspects: on the one hand, it is - the importance of his
work to the scientific community, on the other hand, it is - the use of a scientist social mega environment for
building for their personal and professional
development to improve their research and improve the
quality of its results (in the context of the article we will
consider the second aspect). Methodological bases of
the research: systematic, competence, sociological, and
mega-system qualimetric approaches. Methods:
modeling, methods of quality control, methods of set
theory, relations and graphs. Evaluation (diagnostics)
involvement of scientists in the scientific community -
is more complicated metrology task than the evaluation
of the significance of the results of its research
activities. For the authors it is clear that a mature
scientist (with a high level of research competence)
should intensively use the potential of the social and the
cultural science international environment (community)
for their personal and professional development, to
improve the efficiency of this research activities and the
quality of this results. The proposed indicators can be
considered as group indicator variables reflecting the
level of the behavioral component of the research
competence (scientist). Using social media for
researcher’s potential – it is necessary, but not sufficient
condition for productive research, producing goodquality
scientific results. In this situation, negative
prognosis is more significant: poor use of social media
for researcher’s potential – is a "guarantee" for low
productivity of this research activities and the low
quality of this results. Only the combination of the
highest levels of readiness for research (research
competence) with high levels of other competences (as a
whole - the social and professional competence,
implying the presence of the professional skills of selforganization)
can be the factors of successful research
Conditions in which the work of acoustic magnetic device
proceeds are complicated because of the number of
interconnections. Solving problems under such conditions
analytically is difficult because of many variables
and complexity of some dependencies. The article describes
the conditions in which the work of acoustic
magnetic device, designed for nonchemical treatment of
hydroponic solution, takes place. The criteria, establishing
the initial state of the chains, containing mutual inductance,
are analyzed. The work establishes the criteria
relating the physical parameters of the environment with
the output parameters of the device. The similarity of
conditions of heat transfer on the surface of the device is
provided, and the relation of the scale of temperature
and power lost when heating the ferrite and winding
machine is determined. The criterion of the heat transfer
process is defined. The criterion, determining the relation
of the environment temperature to the thermal
mode of the acoustic magnetic device, is defined. The
criterion of the conditions at the boundaries of the
system and cavitating liquid is determined. It is found,
that the cavitation area appears in the technological volume
of liquid at the work of acoustic magnetic device.
The criterial equation for geometric parameters of different
types and constructions of the acoustic magnetic device is defined. In accordance with the task based on
the third theorem of similarity, the group of criteria that
provides the similarity of the model to the proposed
original by all existing indicators, is selected
The goal of the study is to research a noise-immunity
of pseudo-noise sequence acquisition method for
multicarrier communication systems MC-CDMA,
using a segment of the pseudo-noise sequence. The
goal was achieved by running a simulation developed
in MATLAB. By analyzing the results, we can show
that the developed mathematical model produces the
lower bound for pseudo-noise sequence acquisition
probability. The resulting analytical estimations might
be used during the design phrase for pseudo-noise
sequence acquisition systems for MC-CDMA based
military communication networks
The goal of the study is to analyze the existing
quantum distribution systems, their probable
applications, as well as the issues with their practical
implementation
Grain is of strategic importance and is the basis for
food security. The gross national product share of
grain and its products is about 10-15%. It always
stands out from other types of raw materials, as it is
used to produce the most popular daily foods. According
to the characteristics of management in agriculture,
it should be emphasized that the absence of objective
and timely information at all stages of production of
the plant-breeding, and as a result, non-optimal choice
of technology of cultivation of agricultural crops,
might result in the fact that the cost of labor and material
resources increases significantly, the company
does not receive profits, and sometimes suffers losses.
When selecting cultivation technology for agricultural
crops, an agronomist has a database of more than a
hundred times-personal of alternative technologies for
each crop. It is up to the decision-maker (DMP) to find
specific criteria to select the most suitable (for the
owners and the climatic zone) technology of cultivating
for the culture. These circumstances explain the
relevance of in-depth research of economic and mathematical
models and methods of analysis and evaluation
of the economic efficiency of technologies of cultivation
agricultural crops. The article deals with the
process of adaptation and the possibility of using the
model and the method of binary matrices to solve the
problem of the choice for cropping technology
The goal of the study is to research time characteristics
of pseudo-noise sequence acquisition method for
multicarrier communication systems of MC-DSCDMA,
that allows low hardware requirements and
able to operate in low quality channels. The way of
achieving this lies in using a mathematical model of
algorithm. The achieved results show suitability of
MC-DS-CDMA-signals optimization for pseudo-noise
sequence acquisition efficiency increase. The achieved
results can be applied in MC-DS-CDMA
communication systems development
Augmented reality offers unique ways to display visual
information, in particular the visualization of threedimensional
objects. With AR object can be visualized
directly in the context of its operation. As an example
can be a piece of furniture rendered in the interior, plants
in the garden, the architectural object in the landscape.
Modern consumer devices such as smartphones and
tablet computers, as well as the algorithmic base lead to
the possibility of augmented reality mass usage. The
concept of augmented reality offers a better user
interface for visualization through a combination of
methods of controls and visualization. The camera angle
can be controlled by user’s head or device movements,
which is intuitive and efficient. Method of visualization
of three-dimensional object by combining its image with
the surrounding environment allows better perceiving
the object, its dimensions, and material properties. In
contrast to the traditional visualization approaches, AR
does not require modeling of the environment. Objects
visualization by means of AR can be applied to customer
decision support while buying products. The user is
provided with the ability to visualize an object in interior
or outdoors, where he plans to place it, and interactively
examine the object from any angle. This article attempts
to systemize possible options for interaction with
potential buyers through applications with augmented
reality technology
Tracking is a vast field of research associated with
navigation, robotics, and virtual environments (virtual
reality). Tracking for augmented reality requires higher
level of precision, increased range of action, as well as
work with a wider variety of input data. It is important
that augmented reality technology requires tracking in
real time, which also complicates the task. Correct
visualization of objects in three-dimensional space
requires six degrees of freedom tracking: three position
values (x, y, z) and three angles (rotation around the
respective axes) to determine the orientation. To solve
this problem, different approaches and sensor types are
being used. In this article, we present a brief history of
the development of tracking technology and analyze the
current approaches to implement the process of tracking
on mass mobile devices such as smartphones and tablet
computers. We also describe some issues in
implementing optical marker based tracking for
visualization of large scale models
The purpose of this research is the development of
models and methods of multiparameter diagnostic
effectiveness of educational environments. We know,
that a criterion-diagnostic system for monitoring the
effectiveness of higher education institutions -
educational Macromedia is being designed, which is
not the monitoring of the effectiveness of educational
microenvironments and meso-environment -
departments and faculties. The issue of the research -
to increase the productivity (efficiency) of functioning
of educational environments. The problem of research
is the question of how to diagnose the effectiveness of
educational environments objectively and
comprehensively. The urgency of this problem is due
to: the need to ensure the effective functioning of
educational institutions, their sustainable innovative
development; increasing demand for general and
vocational education, as well as its transition to a
multi-level system. Methodological basis of the
research: a competence-based approach (considered an
important target value of the educational process
formation of the competences and personal and professional qualities of students, integrating
knowledge, skills and readiness for their effective use
in solving of life, professional and educational
problems), metasystem approach (considering the
educational environment as a metasystem, including
relatively independent subsystems - educational
environment of lower level of the hierarchy),
qualimetric approach (considering the effectiveness of
the educational environment as an integrative figure,
which is diagnosed on the basis of estimating a set of
criteria), synergetic approach (considering the
educational environment as a self-organizing system,
and the efficiency of its functioning - as an indicator of
the success of the use of resources for further
development). Synergetic approach is relatively new in
the evaluation of the effectiveness of the educational
process and the educational environment as a whole
