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 article presents the new criteria suitable for the
diagnosis of the productivity of research and the
importance of its results for the scientific community, are resistant to artificially "improve". It is known that
generally accepted measure of the productivity of
research scientists is the h-index, which is calculated
based on a statistical method of scree. This indicator is
applicable to research teams (organizations). However,
the h-index and a number of other scientometric
indicators based on citation, are easy to be artificially
increased (fraudulent schemes action). New
scientometric parameters adequately reflecting the
importance of research results, and not amenable (or
very difficult to) to be artificially "improved" are
therefore needed; moreover, it is recognized around
the world: the true score (not fictitious) of the
significance of the results of a research scientist for the
scientific community - is a complex metrological
(scientometric) task. The authors argued that such
indicators are primarily index latitude demand for
research results, as well as a number of other
parameters of copyright. Despite the fact that authors
indicators, the same as the h-index are based on
citation, their large values indicate that the scientific
community recognizes the results of the research
activities of scientific and pedagogical workers;
moreover, these indicators can be considered as a
criterion to identify really promising (productive)
researchers. The problem of adequate assessment of
the productivity of research activities and the
significance of its results, the authors consider in the
context of the problems (larger problems) of the
effectiveness of educational environments. The
practical significance of research results lies in the
possibility of their use for constructing criteriondiagnostic
apparatus for monitoring research activities
of scientific institutions (including higher educational
institutions). Research methodology: systemic, metasystemic,
probabilistic-statistical and qualitative
approaches. Research methods: cognitive, structural,
functional, and mathematical modeling; methods of
graph theory, sets and relations; system-cognitive
analysis; methods of quality control (theory of latent
variables); methods of probability theory and
mathematical statistics (first of all – a method of
scree), methods of analytical geometry; methods of the
mathematical theory of limits
The purpose of the research is development of models
and methods of diagnostics of methodical competence
of a teacher. According to modern views, methodical
thinking is the key competence of teachers. Modern
experts consider the methodical competence of a
teacher as a personal and professional quality, which is
a fundamentally important factor in the success of the
professional activity of teachers, as well as a
subsystem of its professional competence. This is due
to the fact that in today's world, a high level of
knowledge of teachers of academic subjects and their
possessing of learnt basics of teaching methods can not
fully describe the level of professional competence of
the teacher. The authors have characterized the
functional components of methodical competence of
the teacher, its relationship with other personalprofessional
qualities (first - to the psychological and
educational, research and informational competence),
as well as its levels of formation. Forming a model of
methodical competence of the teacher, the authors
proceeded from the fact that a contemporary teacher
high demands: it must be ready to conduct independent
research, design-learning technologies, forecasting
results of training and education of students. As a
leading component of the methodical competence of
the teacher is his personal experience in
methodological activities and requirements of
methodical competence determined goals and
objectives of methodical activity, the process of the
present study, the formation of patterns of methodical
competence of the teacher preceded the refinement of
existing models methodical activity of scientific and
pedagogical staff of higher education institutions and
secondary vocational education institutions. The
proposed model of methodical competence of the
teacher - the scientific basis of a system of monitoring
of his personal and professional development, and
evaluation criteria and levels of her diagnosis - targets
system of vocational training and re-training of high
school teachers. Innovation policy is a model of
methodical competence of the teacher, and the main
model of the mechanism of its formation - methodical
activity (in close connection with other activities).
Research methods: analysis of scientific and
methodical literature and best practice methodological
activities in educational institutions, modeling,
methods of the theory of sets and relations, methods of
quality control, methods of multivariate analysis
systems. Methodological bases of research: a
systematic, qualimetric, competence and process
approaches. 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 purpose of the research is the development of new methods of the estimation of the importance of scientific journals. It is known that for assessing the significance of scientific journals it is used a universally recognized impact factor, which reflects the average number of citations to the articles published in the magazine for a certain period of time. For a more objective assessment of the significance of the journal in the scientific community we use such indicator as the index of efficiency, which reflects how quickly the articles in the scientific community published in the journal become known and recognized. At the same time, the impact factor as one of the scientometric indices has inherent definite disadvantages, the main of which - the stimulation scientific edition to the artificial reduction of the number of published articles, instead of increasing demands to improve their scientific level. It is necessary to develop a method of assessing the significance of the journal for the scientific community, preserving the dignity of the impact factor and reduce its disadvantages. Application of extra scientometric indicators, in addition to the impact factor and the index of efficiency, will allow assessing the importance of the journal for the scientific community more objectively. Methodological bases of the research are: a systematic approach (considering science as a social institution in close connection with the society as a whole), metasystem approach (considering the scientific community as a metasystem, i.e. a system with a relatively independent components), qualimetric approach (considering the importance of the scientific journal as a latent variables that reflect a variety of criteria), sociological approach (considering the scientific publication as a social system, the intensity of interaction with other society)

Production and processing of grains formed in the national economic system of the country a number of cereals-governmental sectors, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and role of the grain as a commodity in the state economy can not be overestimated. This product is totally liquid, which has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortage was covered by imports. 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 developing a complex of mathematical models and methods for evaluating alternative technologies for agricultural production (using the example of crop production), their software implementation, and the main scientific results of the project
