This article discloses the use of neural networks to
recognize patterns in control charts. To recognize
unnatural situation under control is possible by
analyzing the chart pattern. Neural networks with
reinforcements are the third generation of neural
networks. In this study they are available for
recognition in the management chart patterns. The
article also discusses options for improvement of the
learning algorithm in the form of additional rules for
the synoptic pauses, time constants and switching
threshold neurons
The flowsheet purification of exhaust gases in the
Novocherkassk SDPP after the electrostatic
precipitator on I-th stage of purification set group
cyclone, on the II-nd stage of purification - baghouse.
To determine the particle size distribution of fly ash,
we selected ash from the transport network to the
group cyclone, and the in a group cyclone, and in a
baghouse. With the help of the microscope "Biomed-
3" we produced pictures of ash particles with different
magnification. Granulometric composition of three
selected ash samples were determined according to the
mass content of particles of different grain size,
expressed in percent relative to the weight of dry ash
sample taken for analysis. For size fractions from 10
mm to 0.5 mm sieve method is applied without rinsing
with water, for size fractions less than 0.5 mm sieve
method is applied with water washing. The particle
size of the ash mixture, taken up before the cyclone,
We have presented a table of analogues of mechanical and
electrical quantities of a thermal power plant, which shows
the relation between the useful power of the engine and
mechanical efficiency, as well as the relationship between
engine parameters and regime of its operation; we have
also developed an electro-mechanical analogy, which
helped to get the expressions linking the useful engine
power with shaft speed, engine performance, coefficient of
mechanical resistance and mechanical efficiency with
speed, coefficient of drag and engine performance. Similar
expressions were obtained for the relations of these
variables with other sets of parameters. The article also
shows corresponding graphs. The expressions for the
maximum net power and corresponding speed of rotation
was found. Thus, the efficiency isÐ…. It is shown that in
larger (compared with the extreme) speed, the mode is less
efficient than with the smaller, for the same useful power.
A method is presented to measure the important
characteristics of the finished engine – motor operation and
its rotational drag coefficient used in the resulting
expressions
The article considers the dynamic optimization of the
drying process of grain by proper selection of the required
parameters. The calculations of the optimal

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
Using queuing theory (QT) for the new technology of harvesting of grain crops by the method of «Neveyka», the method of optimal designing of maintenance system and elimination of failures of units used in cleaning technology and post-harvest processing of grain has been considered. On the basis of a systematic approach, taking into account the probabilistic nature of the change of operating factors the methodical directions of validity test of the adoption of the Poisson distribution in the calculation of operating modes were substantiated to optimize maintenance level units and eliminate failures in the operation of the machines, the probability of failure-free operation of harvesting and transport aggregates. The probability of failure-free operation of each type of units used in the cleaning of grain depends on their number and intensity of service. According to the numerical value the probability of failure-free operation of units is equal to the probability of idle units for maintenance and elimination of failures. Since it is impossible to determine separately the value of the probability of failure-free operation for all types of units and all kinds of services at different operating conditions the generalized solution has been offered, this solution is applicable to any serviced unit during both the technical inspection and elimination of failures. By specifying the desired value of the probability of failure-free operation of harvesting units, according to their number we can determine the appropriate ratio between the average length of service and the average period of time between incoming service requirements (technical inspection and elimination of failures) from one unit
Nowadays, a necessary condition for progress in the
field of information technology is wide adoption of
standards and technologies of information systems
used for hardware and software products. Building
software of computing and information systems, based
on the ideology of open systems, allows to
successfully solve the problems of portability on
platforms of various manufacturers, the problem of
interchangeability of components and, most
importantly, ensures the integration of devices and
users in a variety of computing and telecommunication
networks. It should be emphasized the fact that to date
the successful implementation of any significant
projects in the field of information and computer
technology, management of information and
telecommunications is not possible without
coordination of development with existing standards in
the field of information systems and, in some cases,
the development of new standards. In the conditions of
transition to integrated computing and
telecommunications systems, the principles of
information systems form the basis of technology
integration, the establishment of sectoral, regional and
national information infrastructures and their
interactions on a global scale. So, we can conclude that
the technology of information systems today is the
working environment in which the priority is the
development of information and telecommunication
technologies, telecommunication and computer
engineering
System integration, as a kind of information
technology, ensures that a range of services aimed at
the implementation of integration tasks and divided
into several types, including: horizontal, vertical,
distributed and core data format. In addition, this type
of activity has a number of different implementation
methods and occupies a significant share of the IT
market, having a great set of tools of the organization,
allowing optimizing the performance of the tasks by
optimizing the processes of project management and
control, performed by various information systems.
The lack of industry tools to consolidate the
functionality involved in the full cycle of project
implementation in the sphere is an important omission,
adversely affecting the speed and quality of
implementation of tasks. In this regard, there is need
for a new approach to the automation of processes, and
ensure information activities aimed at the solution of
problems on the integration of information systems
and their components, from the stage of task definition
and ending with a commercial operation stage with
further lifecycle support
The article presents a staged scheme for granulation of
solid fraction solids of fermented poultry manure (SF
FPM) in an augered granulator. Granulation process of
material has been reviewed in every stage of
compression. The structural and mechanical properties
of the pressable material were studied. It was revealed
that SF FPM refers to pseudoplastic bodies, which
when exposed to pressure exhibit anomalous
properties. We present a rheological model of the
motion of pressed materials in an augered granulator.
We have modeled a mechanical model of actions at SF
FPM. It was revealed that the compressible material at
voltages generated in an augered granulator at the area
of plasticizing was acting like an abnormal liquid. This
liquid obeys the regularities of Newtonian liquids
