In the article we have considered the self-balanced
potato sorting machine differing from existing designs
of self-balanced potato sorting machines with an oscillatory
electric drive. That drive uses a linear induction
motor. As the counterbalancing device, the method of
the duplicating mechanism is applied. The duplicating
mechanism is a specular reflection of the main working
body, and also participates in technological process.
Its application in the drive of machine allows not
only to increase efficiency of cleaning, drying and
sorting of potatoes, but also to increase reliability of
sorting installation that corresponds to the newest
tendencies of development of technology. We have
brought the mathematical model of the offered electric
drive of potato sorting machine, which is implemented
in the environment of object and visual modeling of
Matlab |Simulink|. The mathematical model allows
investigating influence of parameters of the linear induction
electric drive on parameters of oscillatory process
of working body in dynamics. The developed
technique of research and the created experimental
potato sorting machine with the linear induction drive
have confirmed theoretical researches. The main kinematic
sizes of machine and technical parameters of
individual nodes are determined. It is shown, that the
efficiency of inertial transportation can be increased
for 20% in comparison with the classical drive from
the motor of rotation. Results of research will allow to
realize energetically and technologically effective potato
sorting machines with the linear induction drive
In poultry industry, animal breeding, greenhouses and
vegetable stores a significant amount of fans with
asynchronous motors is used to create a microclimate.
The fan speed of the fan should be regulated in order
to improve the efficiency, so the multispeed motors are
used for the fan drives. Line produced two-speed motors
with a proportion of the poles number 1:2 have a
polar-switched Dahlander stator winding. Two-speed
motors with a proportion of the poles number 3:2 and
4:3 have only one stator winding which is poleswitched
by the method of amplitude phase shift keying.
A drawback of the windings is that they have different
energy indicators at different spin rates. In order
to create rational diagrams with switching according to
the number of poles, which is multiple of three, it is
proposed to implement a polyphase MMF modulation
of the three-phase winding. As a result of the study,
there were procured the stator windings at 4 and 6
poles, which enabled to change the spin speed of the
motor in the fan drives without breaking the drive
power circuit by the scheme Δ / ΥΥ
The article proposes to use the automated systemcognitive
analysis (ASC-analysis) and its software tool
which is "Eidos" system to solving multiparameter
typing, system identification and cartographic visualization
of spatially-distributed natural, environmental
and socio-economic systems. Imagine, that we have an
original point cloud with coordinates (X,Y,Z), each
with known values of gradation descriptive scales of
nominal, ordinal, or numeric type S(s1,s2,...,sn). Then
the "Eidos" system provides: 1) building a model that
contains generalized knowledge about the strength and
the direction of the influence of descriptive gradations
of scales at Z=M(S); 2) estimation of the values of Z
for points (X,Y) described in the same descriptive
scales S(s1,s2,...,sn), but not a part of the original point
cloud; 3) a cartographic visualization of the spatial
distribution of values of the function Z=M(S) for
points outside the initial cloud, using Delaunay triangulation.
Basically, this means that the "Eidos" system
ensures recovery of the unknown function values on
the grounds of the argument and implements it in a
generic setting, independent of subject area. We propose
a new scientific concept called "Geo-cognition
system", which is defined as a software system that
provides conversion of source data into information,
and knowledge in visualization and mapping of this
knowledge, resulting in the cognitive map becomes
graphics. This feature can be used to quantify the degree
of suitability of the watersheds for cultivation of
certain crops, the evaluation of the ecological situation
on particular territories on the structure and intensity
of anthropogenic load, visualization of results of forecasting
of earthquakes and other unwanted risks or
emergencies, as well as for solving many other similar
mathematical essence of tasks in a variety of subject
areas. We have also shown a simple numerical example
The article contain the peculiarities of testing asynchronous
generator with sixzone winding on the basis
of the asynchronous motor series 4A100S4 and analysis
of obtained characteristics. Circuit parameters of
the stator winding can significantly affect the characteristics
of the asynchronous generator. Asynchronous
generator was tested with a stator winding connected
star, autotransformer and sectional winding. Use chastising
windings opens the possibility of applying various
circuits of capacitors and the load to asynchronous
generators, which in turn affect the efficiency and stabilizing
properties of the electric machine. Asynchronous
generators to test with sectional winding by confirmation
of theoretical calculations for determine the
most optimal scheme under connect capacitors and
load, testing the stator winding. The volume of testing
for asynchronous generators standard is not defined, so
we proposed testing method, taking into account the
design features of the stator winding. Asynchronous
generators were tested with the help of special equipment
with the use of analyzer of energy power quality.
Article contains characteristics of idling, short circuit
and others, considered the heat mode. On the basis of
the results we have determined the parameters of the
circuit, the efficiency and power factor of induction
generator
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
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 presents the mathematical model for
determining the temperature after passing trough
nozzles of press-granulator, which allows to take
into account heat loss through the exterior surface
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

Japan and the European Patent Organization. We have
systematized the patented methods, the
implementation of which can increase the shelf life of
vegetable raw materials. The study led to the
conclusion of the usefulness of developing innovative
ways of ensuring a stable quality of vegetable raw
materials in the process of storage using
biopreparations
The article presents an analysis of the existing approach
to automobiles technical maintenance in
agriculture. We have pointed out that in modern
conditions it is impossible to forecast the automobiles
maintenance operation frequency and as a
result its improvement as well. It is obvious that
one cannot achieve the considerable increase of
maintenance operation efficiency by separate means
and there exist the necessity to treat it as a system
and use the up-to-date methods to investigate and
improve complicated systems. We have made a
conclusion that the increase of maintenance operation
efficiency is not possible without some rational
strategy of maintenance operation and repair. We
have shown that the program of maintenance operation
and repair being an integral part of automobiles
technical maintenance has considerable effect on
maintenance and repair quality. As a result, there
is some necessity of the developed system of
parameters diagnosing and control in technical
maintenance and repair. We have shown that to
get sufficient diagnose information one needs
selection of the controlled parameters which
give maximum information about the object
technical status taking into account possible characteristics
of its operational faults. We have discovered
that in order to solve the task it is necessary to
have the object’s information pattern, calculation of
possible characteristics of the controlled object being
in good or bad order due to some parts fault,
evaluation of information brought by every parameter
and determining parameters to be diagnosed. We
have proposed to evaluate the parameters’ information
value with the help of information entropy as
uncertainty measure that is one of the main concepts
of the information theory. Because of solving
the task, we have got the aggregate of the controlled
automobile parameters orderable according to the
amount of information
