Nowadays some branches of the industry need hybrid
or cascade systems of electric drives. Electric
drives use up to 60 percent of all developed electric
power therefore with improvement of massdimensional
indicators and power characteristics of
the considered devices necessary technical characteristics
are reached and losses of electric energy
decrease. When creating electric drives of various
designs, it is important and rather difficult to calculate
an electromagnetic system. Classical approach
to design of data of systems has a number of shortcomings
that demands creation of new approaches
or adjustment and addition of the known methods
and approaches. In the article, another approach to
design of the developed systems of the electric
drive is offered
Problem having elementary formulation makes us
look for its easier solution. So the combinatorial
method of positive integer’s factorization is an
attempt to do it. The combinatory method possesses
simple algorithm, leading immediately to finding out
all the factorizations and identification of all prime
numbers on any interval of the positive integers.
Prime numbers don’t carry any information except
their own magnitude. Composite numbers, possessing
divisibility properties provide possibility to discover
the law of their distribution. The achievement of this
purpose also completely solves the problem of
finding out the law of prime numbers’ distribution

are determined. Implementation of system of
controlling in the organization is offered
The object of the study was the sweet pomace of red
varieties of grapes grown in village Taman Temryuk
district of the Krasnodar region. By grinding in a
laboratory mill and drying in a drying oven at a
temperature of not above 60 ºC, a powder is obtained
from the mash. Its quantitative chemical analysis has
been carried out. The mobile forms of metals and the
total content of metals are determined. The content of
mercury, lead, arsenic does not exceed the permissible
levels of the maximum content of toxic elements in
flour confectionery products. The influence of powder
from grape pomace on the quality of the finished
product and on the properties of the pastry test was
studied, as the control sample was chosen the recipe
for the sugar cookies "Carrot". A part of the flour was
replaced with grape-dried powder in amounts of 1 %, 2
%, 5 % of the mass of wheat flour of the highest grade
in the test. The recipe of sugar cookies with the
addition of powder from grape pomace and without,
calculated on 200 g of finished product, and
organoleptic parameters of the finished biscuit is
given. It is established that the use of grape-dried
powder allows to increase the mass fraction of dry substances and to reduce the mass fraction of sugar in
confectionery products, as well as to enrich them with
mineral substances, microelements, which are
necessary for normal functioning of the organism.
Biscuits with the addition of powder from grape
pomace are a good source of ballast substances
reducing caloric content, which contributes to the
removal of harmful substances from the body:
cholesterol, heavy metal salts, etc
Currently, we are constantly improving the recipes of
fish feeds, this reduces the cost of feed per gain, and it
overall decreases cost of fish. We search for
alternative cheaper sources of nutrients. Leftovers of
vegetable oil and oil extraction industry such as oil
cakes and meals have been used as high-protein feed
additives for a long time. This requires a strict
scientific control, precluding the possibility of their
harmful effects on animal health. In this regard, there
was a comparative analysis of the chemical and
amino acid composition traditionally used in
compound feeds for sturgeons of sunflower cake and
feed concentrate from "Sarepta" vegetable raw
materials. During the research it was found that
"Sarepta" is better than sunflower meal considering
protein and essential amino acids content

A methodology for a multilevel system approach to
integrated optimization of processes of harvest,
transportation and cleaning of the grain during the
harvest by the method of «Neveyka» has been
developed. The main method of research - is a
queuing theory of all components of the yield except
straw. The System consists of 6 interconnected
subsystems with their inputs and outputs, and its own
optimality criteria. On the first level of optimization,
the most efficient way of wheat harvest «Neveyka»
has been proved. On the second level - the total
duration of the harvest with allowance for 4-5
cultivated wheat sorts, each of which is harvested
within 5 calendar days, was optimized. The third
level proves the requirement of combine harvesters
and transport vehicle. On the fourth level - the
combinations of harvesting and transport units are
optimized on the criterion of the minimum amount of
the loss on the mutual expectations of harvesters and
vehicles. The fifth optimization level proves the
capacity of the reception station of the grain storage,
where the main criterion for optimality is the least
amount of losses on the mutual waiting time of the
transportation vehicles, and the additional criterion is
the minimum waiting time of vehicles in the queue.
On the sixth and the final stage the specific annual
economic effect (rub/ha or rub/t) from the
implementation of the proposed technology is
determined. It is established, that during the grain
harvesting, transporting and processing of heap there
are elementary or Poisson probability flows of
requirements for service. The Representation of
harvesting - transport link in the form of closed
queuing system of independent harvesting unit. An
approach to the justification of failure-free operation of a station for cleaning grain heap and storage of
grain and chaff is presented
This article provides results of studying the world
achievements in modeling social systems in the
aspects of personality, group, and social institute (e.g.
the state and army). Through prism of conflict, we
review research methodology for modeling social
identity, social navigation, geopolitical processes, and
command and control systems of the enemy. We
discuss four agent-based models of social identity:
SCIPR, MetaContrast, PS-I, and SILAS. We examine
Spence model for modeling social navigation. Basic
principles for modeling relations between the states
are considered using ontology approach. The
presented model allows systemic analysis of various
micro- (intrastate) and macrolevel (external) variables
and relations between them. Modeling command and
control system of the enemy is implemented as a part
of an automated decision support system that tackles
the problems of enemy structure identification as well
as classification of objects and relations within the
structures. The object of study are approaches,
methods and models for representation and analysis of
group interaction. The subject of study are processes
of agent self-identification and interaction, formal and
informal organizations, the states and public institutes
as well as processes and principles for group
formation and mechanisms for behavior control.
Research methodology: social network analysis,
ontology approach, theory of graphs and hypergraphs,
multiagent systems
In this article, the general structure of technologically
complete production chain of the integrated production
system of agroindustrial complex was considered.
Three different variants of creation of the production
chains are described. The main distinctions in activity
of chains consist in a source of raw materials. Any
technologically full vertical chain includes three stages
– production of raw materials, storage and processing,
realization. Each of stages is characterized by different
situations of the risk. Stages of process of functioning
of a production chain were considered in this article.
Also, the qualitative analysis of risk for all stages is
made and the results of this analysis are considered.
Results of this analysis became a basis for
improvement of stream model for determination of
efficiency of the technological chain taking into
account a risk component. In the article, the algorithm
of an assessment of efficiency of the technological
chain of the integrated production system taking into
account a risk component at the stage of creation of a
material stream is also described
The article discusses a model of rocket motor of
electromagnetic type, consisting of a source of
electromagnetic radio frequency oscillations and the
conical cavity, in which electromagnetic waves are
excited. We have created a multi-dimensional
transient numerical model describing the process of
establishing electromagnetic oscillations in the
resonator, taking into account the finite conductivity
of the walls. Separately, the standing waves in the
cavity with conducting walls have been simulated. It
is shown that the oscillations mode in the conducting
resonator different from that in an ideal resonator,
both in a case of steady and unsteady waves. We have
built a dynamic model taking into account the thermal
conductivity and electrical conductivity of the walls,
waves and particles emission and vacuum
polarization. We have also developed a dynamic
model enables to optimize a thrust force on a
considerable number of parameters without the
involvement of the hypotheses about the physics of
the phenomenon. We run the optimization of the
operating parameters of the device, namely by the
excitation frequency, the frequency of the modulating
signal, the magnitude of heat losses of
electromagnetic energy by thermal radiation in the IR
spectrum, the parameters of forced heat transfer and
the temperature dependence of the resistance of the
material of the cavity walls. It is found that the pulse
modulation greatly improves the efficiency of
conversion of electromagnetic energy into thrust. The
mechanism of formation of traction, adjusting the
metrics of space-time, the current contribution of
elementary particles, the Yang-Mills and
electromagnetic fields is proposed. It is shown that
the contribution of the elementary particles in the
thrust force is proportional to the electrical
conductivity of the system multiplied by Abraham
force
