In agricultural production, the direction of introduction
of renewable energy for power consumers remote from
the external electrical network is relevant. Here,
prospects are revealed in front of the solar PV stations.
One of the main functional units of solar power is
inverters that convert the DC voltage of the solar
panels into alternating current. The article describes
the advantages and disadvantages of the main methods
of voltage regulation of the autonomous inverters of
solar photovoltaic power plants. We have proposed
new structural designs of autonomous voltage
inverters, described their advantages, features of
design and operation for voltage stabilization. We
suggest stand-alone inverters designed using high
frequency link, which will significantly improve mass
and dimensions parameters of the converter. Due to the
use of single-phase transformer with a rotating
magnetic field in stand-alone inverters, we improve the
efficiency of the converter and the reliability of the
work. Patents of the Russian Federation confirmed the
novelty of technical solutions of the considered
schemes of autonomous voltage inverters. Structural
schematics of the voltage regulators considered in the
article, as well as features of their work, will allow to
increase efficiency of preliminary works on
development of autonomous voltage inverters with
improved operational and technical characteristics for
solar photovoltaic power plants

The competitiveness of any company engaged in the
wholesale or retail sale of goods and services is
substantially determined by the level of quality of the
services provided. For the accompanying business of
vertically integrated oil companies, the criterion of
quality service is not an exception. Currently, cafes
and shops at the refueling complex are not only a
convenient service for customers, but also a solid
source of additional revenues for the largest oil
companies, each of which seeks to make the retail
network attractive to customers by offering a wide
range of goods in stores, ready meals in a cafe, and
related services. To satisfy the needs of the client, it is
necessary to offer a wide, but rational assortment of
goods at the refueling complexes. The claimed goods
must always be at the refueling complexes. The lack of
goods necessary for the customer on the shelf means
the loss of sales and profits, the order and location of
goods that are not in demand - the formation of
surpluses, returns to the supplier and write-offs. This
also affects the overall economic performance of the
company. In this regard, the increase of logistics
service is one of the priority tasks of the
accompanying business of vertically integrated oil
companies
In the dairy industry, the segment of yoghurts and
yoghurt drinks is one of the most dynamically
developing. Competition contributes to the production
of high quality products. The transition to market
relations encourages producers to use new prescription
ingredients in the production of various yoghurts. In
addition, it is essential to improve the existing ones
and create qualitatively new technologies of products
with a directed change in the chemical composition.
Sour-milk drinks not only satisfy the physiological
needs of the body, but also have a preventive and
therapeutic purpose. Utilization of these products
contributes to the prevention of numerous diseases, as
well as life prolongation and increase of working
capacity. The dietary properties of sour-milk drinks are
determined by the presence of “live” beneficial
microflora and persist for a long time, as long as this
microflora remains viable and pure. The article
contains data distinguishing the effects of the use of
commercial fermentation starters EKOKOM Laktina,
TM GoodFood, Kaprina on the qualitative
characteristics of dairy clots. The article specifies the
influence of fermentation starters and vegetable fillers
on the organoleptic parameters of the final sour-milk
product. The authors of the article further present data describing the organoleptic and physicochemical
quality profile of yoghurt enriched with vegetable
fillers, obtained by introducing commercial
fermentation starters of various manufacturing
companies
The work is devoted to the topical issue of increasing
the productivity of computers. It has an experimental
character. Therefore, the description of a number of
the carried-out tests and the analysis of their results is
offered. Previously basic characteristics of modules of
the computer for the regular mode of functioning are
provided in the article. Further the technique of regulating
their parameters in the course of experiment is
described. Thus the special attention is paid to observing
the necessary thermal mode in order to avoid an
undesirable overheat of the central processor. Also,
operability of system in the conditions of the increased
energy consumption is checked. The most responsible
moment thus is regulating the central processor. As a
result of the test its optimum tension, frequency and
delays of data reading from memory are found. The
analysis of stability of characteristics of the RAM, in
particular, a condition of its tires in the course of experiment
is made. As the executed tests took place
within the standard range of characteristics of modules,
and, therefore, the margin of safety put in the
computer and capacity of system wasn't used, further
experiments were made at extreme dispersal in the
conditions of air cooling. The received results are also
given in the offered article
An overview of various ways of preparing roses for
industrial processing with the aim of obtaining rose
essential oil is presented. Based on the patent and
information retrieval data, features of new, scientific
developments in this field, which have not yet found
wide application in industrial processing, their
advantages and disadvantages are discussed. The
conclusion is made about the need to search for new,
modern, environmentally safe ways of preparing raw
essential oil for industrial processing
The problem of availability and quality of medical
care is a priority nowadays. The Medical Centres for
Information and Analysis (MCIA) have been created
in the regions for the purpose of gathering information
about the quality of services rendered and subsequent
data are transferred to the Ministry of Health Care of
Russia. Regional MCIA are complex and developed
systems that solve simultaneously many problems,
one of which – the organization of collection,
processing, recording and analysis of information on
the provision of medicines. It has been established in
the course of conducting an analytical review of
examination systems of preferential recipes and
information protection that the level of automation of
routine operations of the MCIA activity of the
Krasnodar Region is high, but there is no qualitative
information processing. As a result of the comparative
analysis it was determined that the automated review
of medical prescriptions for privileged drugs allows
identifying abnormalities in the reference data without
any analytical conclusions about the causes and
consequences of the case. Taking into account the fact
that in the provision of essential medications there still
exists quite understandable demand for software
products which automize the routine work of
specialists, it remains obvious that the directions of
improvement of software products are not
implemented fully. In this regard, the present research
proposes measures to improve the existing systems by
integrating with the information system of medical
and economic control of the prescription of medicines
The article is devoted to the analysis of the use of
large data processing technology in information
systems of territorially distributed complexes
Results of engineering and scientific search of
improvement of resource-saving machine technologies
of finishing and cleanup processing of cars details,
development of new camps and technologies are
presented. The possibility of low-frequency
fluctuations with big amplitude can be implemented
due to assembling flat or curvilinear elements on
external surfaces of the relative screw reel. The use of
computer modeling enabled us to obtain a relative
screw drum that provides not only giving movement to
loading masses with a big fluctuations amplitude, but
also compression of loading masses in the process of
their motion from loading to unloading. In such
machines increase in processing efficiency is reached
not only due to achievement of great movement
amplitudes values of the loading masses, but also at
the cost of compression of loading masses in
processing and intensity increase of their mixing. The
scheme of the machine for continuous processing with
mechanization of separation of details from working
environments particles is provided. Results of
researches of quality and surfaces micro hardness
change processed in the offered machines designs
show that details processing time makes 3-6 min
The article formulates and solves the task of discrete
control in the thermophilic stage of the composting
process. It is shown that considering the relay control
entity to maintain specified process conditions requires
the organization of the sliding mode. We have solved the
problem of minimizing the temperature deviation of the
substrate from the set values and the deviation of the
oxygen concentration in the gas phase of the bioreactor
from the specified values. The article shows the
algorithm to compute the discrete control of the
composting process in the thermophilic stage. This work
was prepared in the framework of the scientific project
16-48-230441 a(R) "Mathematical modeling of the
processes occurring in the automated installation for
year-round production of organic fertilizers in the
conditions of the Krasnodar region", financed by RFBR
and the administration of the Krasnodar region
