The article shows that the distribution of temperature regime in EIS corresponds to a known process of cutting and surface plastic deformation with heating details with acetylene-oxygen burner, which allows to combine the process of welding filler powders with finish-hardening treatment with combined instrument in the form of a two-pole bracket
The simulation of the physical and mathematical model of the mounting mechanisms of a forest soil-tilling implement is developed. The model allows, on the basis of computer experiments, to determine op-timum geometrical parameters of the mounting mechanism

The given developments are devoted to modeling of control systems by ecological safety of foundry manufacture. In a working zone of foundry shops except for a dust the significant amount of polluting substances is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The given dust is most dangerous to health of the working personnel and creates problems when clearing the air
The article discusses the model of a neuron with
memory. The proposed model is formed based on the
model of the dynamic neuron. The proposed solutions
allow to efficiently model dynamic processes and to
provide a two-level scheme for evolution of neural
networks. The first level of evolution is achieved using
traditional neuro-evolution models that allow you to
create or to modify basic network settings. The second
level allows you to track the history of the
development process. The article presents a formal
description of the proposed models and algorithms of
functioning of the network, is the rationale for the use
of the proposed models
In this work, we have analyzed the multiple
literary sources and summarized the material
regarding beet dietary fibers. Their composition,
physicochemical, physicomechanical and
hygrothermal properties were studied. The study of
the particle-size distribution showed that the
content of the insoluble fraction exceeded the
content of the soluble fractions in all the samples.
The use of the secondary products of processing of
the plant raw material is also critical; they allow
improving the preventive properties of products
and enriching them with dietary fibers, protein, and
mineral elements. The properties and quality of the
raw material are, to the large extent, determined by
and depend upon its granulometric composition,
that is, upon the size of particles that compose this
object. The authors determined the granulometric
composition of the studied nutritional supplements.
It was found out that the use of the combination of
the impacts together with the abrading impact led
to the intensification of the process, a decrease in
the milling time and the uniformity of the obtained
granulometric composition. The choice of the
vertical mill as milling equipment in combination
with the metal balls added to it to increase the
efficiency of milling and uniformity of the
granulometric composition of beetroot fibers was
proved experimentally
The problem of environmental protection from toxic contamination, i.e. toxic products contained in exhaust gases, is one of the most pressing in the modern world.
Currently, internal combustion engines and vehicles of transport and technological machines rank first in power supply in the global energy balance. The total amount of pollutants released into the atmosphere by tank-automotive equipment exceeds more than three times the emissions released by industrial companies. Besides the vast majority of tracked and wheeled vehicles are equipped with diesel engines, which excel gasoline engines in harmful substances released together with exhaust gases. Therefore the problem of emission control becomes more and more urgent. The aim of this study is the analysis of modern means and methods of reducing the toxicity of exhaust gases released by diesel engines.
The existing methods of emission control can be divided into four groups: improving the design of the internal combustion engine; the accounting of operational factors affecting the toxicity of exhaust gases; the use of unconventional fuels; the exhaust gases cleaning in the exhaust pipe. Each method has several major ways to reduce the emission of toxic substances, which are often mutually complementary. We have cited the research date of influencing each of the methods on the emissions of toxic substances in exhaust gases. We have found that reducing the emission of toxic substances in compliance with Euro-6 requirements can only be obtained by the simultaneous use of several methods of reducing emissions.
We have proved the effectiveness and economic feasibility of using combined neutralizers to clean exhaust gases
