The article shows the influence of pre-treatment
with a solution of sodium chloride and a solution of
succinic acid in various concentrations to clean the
baskets-of inflorescences of sunflower from the
ballast towards the pectin substances. The
application of these solutions helps to reduce
protein, coloring and aromatic substances contained
in baskets-inflorescences of sunflower, as well as
easing the connection of calcium ions with
protopectin in inflorescences of sunflower, in the
future, cleaned baskets-blossoms of the sunflower
are used as raw material for producing high-quality
pectin extract
Hereby are represented: method and results of experimental research for substantiation of rational operating mode for honey centrifuge electric drive. Empiric model of influence of honey temperature (from 20 to 30 оС) and honey humidity (from 17 to 21%) on initial rotating speed of centrifuge was worked out. Rational operating mode of honey centrifuge electric drive consists of 3 stages of honey output. Rotating speed of drum with allowance to the honey temperature and humidity for each stage was substantiated. There is an example of model using. Recommendations for application of research results are given
Modern extraction systems are characterized by a change in the parameters of the production cycle under the influence of a number of causes caused by the structural dynamics of systems. Information systems can successfully function by solving the tasks of collecting, processing, analyzing and distributing real-time information, which involves the use of modern information technology methods. With increasing requirements to the volume, speed and quality of information on the progress of extraction processes, modernization of information systems is required, allowing to make informed decisions by management structures. In the article the regularities of mass transfer of n-components in carbon dioxide of the solid-liquid system are considered. The effect of spontaneous interfacial convection in the mass transfer of individual components under the influence of an electromagnetic field of low frequency is detected. The joint mass transfer of extractive substances during spontaneous interfacial convection leads to an increase in the mass transfer coefficient of eugenol compared to its diffusion mass transfer
The article discusses the application of the theory of
vibration in the design and creation of devices seeding.
The ways of solving the problem of creating a single
universal device for seed and fertilizer using vibration
processes influencing the change flow rates when sowing
seed from the hopper. The ability to transfer the
balance of volume of crops and fertilizers at the expiry
of their bunker in order to bring the different flow rates
for identical simplifies management processes noncontact

In the article, we have calculated the cost of the combined energy of the proposed four types of the multifunctional units and their optimal system for the conditions of grain harvesting in the Krasnodar region; the analysis of the costs has also been reviewed
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
The article describes the methodology of decision-making for optimization of wood harvesting plans. The methodology has been realized as a corresponding component of the Computer Information System developed for forestry logistics
The technique relates to the area of distribution of key
information in cryptographic communication systems.
The purpose of the work was to solve the problem of
increasing the speed of distribution of key information
for special bodies of federal bodies of critical facilities
in the conditions of network-centric management and
creating alternative options for the distribution of key
information when key documents are compromised to
special equipment. By applying the methodology, a
solution to this problem is achieved by applying a key
distribution method based on asymmetric
cryptography using symmetric polynomials
In this article, we have examined the methodology of
acoustic measuring with the purpose to create safety
conditions for the activity of agricultural machines
operators, in foremost harvesters and tractors. We
should underline that such studies are based on the
state standards that are aimed at improving the level of
comfort of the activity of the operators of tractors and
harvesters and maintaining their working capacities.
Therefore, there is a need for a thorough analysis of
the current regulatory legislation (standards that are
applied) in combination with analysis of mathematical
support of measuring devices (sound level meter).
Besides, there is a need for creating strict sequence of
actions of the sound level meter operator (algorithm)
in combination with the method of conveying
information that is adapted to the experiment. At the
enterprises, organizations and establishments control
of the noise level at working places is checked no less
than once a year. The State Standard 12.4.095-80
provides the basis for measuring, position of the
control point in the booth, the frame and
characteristics of measuring, mode of activity of
engines and parts of harvesters, the amount of
measurement samples (3 precise measurements),
estimation of measurements and their correction,
equipment, methods of measuring the results,
temporary characteristics of measuring by the sound
level meter in “slow” mode and frequency correction
In this article, on a small and evident numerical example, methodological aspects of a process engineering of detection of knowledge from the trial-and-error data explicitly are considered, representation of knowledge and its usage for problem solving of forecasting, decision making and data domain examination in system-cognitive analysis (SC-analysis) and its programmatic toolkit - intellectual "Eidos" system are shown
