The article discusses the methodology of the study of
influence of the angles of the spray nozzles on the
quality indicators. The authors considered three
options for placement of dispensers with preset angles.
To determine the quality indicators we used a special
technique based on the use of a personal computer
equipped with a scanner with high resolution for
entering information directly to the trapping surfaces
Hardening of clay soil manifests in the form of
increase of the resistance of sample to shear
deformation. The shear tests of normally compacted
and overcompacted soils give values of peak strength
at small strains and long-term strength at high. A shear
test with constant strain rate of deformation (CRD)
with continuous recording of resistance encounters
uneven resistance change and the cyclical rate of
change of resistance (RCR). The identification of
cycles of the SIS allowed us to divide the deformation
in each cycle for elastic and inelastic, corresponding to
the ascending and descending branches of cycle. On an
interval of the total resistance, the increases of the
increment of inelastic strain are positive up to some
critical value of the total deformation of the sample at
which their sum reaches a maximum. This maximum
is adopted as a measure of hardening. With further
shearing of the sample, inelastic increments are
negative, and their sum is monotonously decreases and
reaches negative values for the total destruction of the
sample. This value is taken as the softening. A
symptom of total failure of the sample is the decline of
absolute values of inelastic increments of resistance to
zero. In general, the trend of the increments of inelastic
and elastic increments of the resistance of the sample indicates the development of the destruction of the soil
sample on the sliding surfaces and, in particular,
yielding of the total surface. The sum of elastic
increments of the resistance monotonically increases
throughout the shear
The object of the study is bored piles and their joint
work with clay soils. The analysis of the field of static
tests of bored piles, arranged by continuous flight auger
technology (CFA), was carried out by repeated loading.
Curve of settlement and the rate of its development
from the applied force was obtained. Linear relationship
reducing the amount of settlement in the second cycle
from residual displacements after unloading pile on the
first cycle was found. There was a relationship
increment of settlements in the second cycle from the
involvement of the bottom end in the work
Waterflooding helps in the recovery of great amount of
oil that would have otherwise been abandoned in the
reservoir that is depleted. A reservoir in the Niger
Delta, Reservoir X has been used to illustrate this.
Reservoir X had oil initially in place as 7.345 MMSTB
and was produced for some time with the reservoir
natural energy. The remaining oil in the reservoir as at
the time that the natural energy of the reservoir was no
more sufficient to produce oil was 2.96MMSTB. The
reservoir has been left as depleted reservoir with the
remaining oil in it. But from the analysis conducted in
this work it is seen that if secondary oil recovery
project by waterflooding is embarked on the reservoir,
part of the remaining abandoned oil would be
recovered. With the specifications given, about
1.22MMSTB of the 2.96MMSTB of oil in reservoir X
would be produced as at the breakthrough time of 580
days. Moreover, considering the economic aspect of
the project, reservoir X and is good to be invested in.
From the NPV calculations performed, it is seen that
the NPV of reservoir X at discount rate of 10% is
$4.13 million
Car license plates recognition problem is one of the
typical tasks of computer vision. Video surveillance
software usually provides license plates recognition
function. Meanwhile, there are many approaches to
solve this problem, where template-based methods are
the most common. Such methods providing predictable
and short enough execution time, and little percent
of mistakes. However, such methods are far less effective
in case there is a need to recognize car’s license
plate, which may be located in unpredictable place,
typed in undefined font and on non-standard background,
or without strict formatting. For example,
USA car license plates. One of the methods to increase
effectiveness and quality of such license plates recognition
is to use neural networks. It is assumed, that
neural networks usage can significantly increase
recognition quality. Nevertheless, neural networks usage
entails difficulties of it’s training, and often becomes
less efficient as template-based methods usage.
This article discusses probability of usage of convolutional
neural network, which was trained using MNIST
(Mixed National Institute of Standards and Technology)
database. This article is a review of usage of templates
and neural networks for car’s license plate
recognition in terms of quality, performance and complexity
of the usage
Insects are a major component of natural biocenoses
and agrocenoses. One of the largest and most numerous
families are ground beetles (Carabidae); their
number, according to various estimates, is more than
30,000 species. For Carabidae beetles it is common to
have different ways of eating, a place of habitation,
occupied layers, seasonal and daily activity. They live
both on the surface and in the soil, more rarely on
bushes and trees. The types of the family of ground
beetles – active beetles with long, thin antennae of
uniform thickness, long elytra and long legs, adapted
to running. Their sizes vary from a few millimeters to
10 cm. As active predators, ground beetles play a huge
practical importance, destroying pests before reaching
the last threshold, thereby providing a natural regulation.
Based on the fact, that the number of beetles is
large, and their sizes are sometimes only a few millimeters,
there is a problem of determining the species
of these insects (or their identification), therefore it
took a special tool, which, on the one hand, facilitate
obtaining data about these insects, and on the other
hand, would increase their accuracy. This article proposes
a new (to this subject area) approach to identify
different species of ground beetles along their outer
contour with the use of software tools for automated
system-cognitive analysis (ASC-analysis) – the universal
cognitive analytical system called "Eidos,"
which is well-proven in the study of other objects. The
reason why it was decided to use this system is that
normal (standard) identification of ground beetles,
have certain disadvantages: the human factor (manifest
error in the determination); quite time consuming; the
inability to increase the number of criteria to improve
the reliability of the model comparison. This article
aims to overcome these drawbacks, by the use of universal
cognitive analytical system "Eidos", the automated
system-cognitive analysis (ASC-analysis). A numerical example is given
The article presents the fact that the composition of fur
models has significant importance for the customers,
surpassing even the importance of quality and comfort
clothing for the consumers. It systematizes features of
the compositional solutions of fur garments,
determining the integrity of the image and the artistic
unity of structure components. It describes methods of
combining different types of fur and various textile
materials in one product, as well as types of decorative
finishes. It shows the influence of different height of
hair, color and texture of fur on visual and tactile
perception of spatial forms and appearance of fur. The
subordination of the constituent parts of form, rhythm
of expressive elements and the presence of asymmetry
details give a dynamic composition solution of fur
garments. To improve the aesthetic properties and
enhance consumer value, a composition of fur garment
should be holistic, proportionate, harmonious in color
and texture of the fur, of decorative trim, with the
rhythmic arrangement of parts. The composition of the
external forms of fur clothing takes into account visual
and tactile features of fur, a variety of design cut,
ensures the artistic expression of clothing
Creation of hydraulic fracturing in the physical structure
of the reservoir rock is one important way to improve the
productivity of oil and gas wells. These artificial
channels increase ability of the reservoir rock for
conducting hydrocarbons to the wellbore. In this study a
new approach has been proposed for optimization of
fracture half length in hydraulic fracturing operation.
Also, this new method that is a combination of various
fracturing geometry models has been proposed for
modeling the hydraulic fracturing geometry. We have
shown that there is a reasonable agreement between the
result of pseudo 3D fracture geometry model and the
predicted results from the proposed approach
Nowadays there is a deficit of irreplaceable and
physiologically necessary nutrients in everyday ration
to a large extent connected with unfavorable
environmental conditions and the increase of
morbidity of humans of all ages cause the cute
necessity in the creation of functional food that is
products with additional functions which are healthy
nutritive and physiological characteristics. One of the
main demands under their creation is in the positive
influence of introduced products on the food value of
products because they must be enriched with
ingredients which have antioxidant properties.
Therefore, nowadays the introduction of functional
meat-plant products will promote the effective
improvement in the direction of prophylaxis of
different diseases. In Russia, the concept of healthy
nutrition became a part of state politics. The aim of
this politics is the conservation and consolidation of
population’s health and the prophylaxis of diseases. In
this work, there was considered the technology of the
production of meat-plant tinned food of functional
purpose enriched with nutrients and intended for
preventive human nutrition, for those who are in the
conditions of harmful influence of environment and
professional activity. There were described the
advantages of the given developing, there were
recommended the introduced into the product
components of functional purpose
The article focuses on current issue of improving the
reliability of water intake buildings in the Far North.
We have given special operating conditions of these
structures, particularly ice drift, shore ice piles, windrowing
ice fields and erosion of the bottom of the
moving ice field with keel protrusion. We have described
physiographic, structural and morphological
conditions of the construction site, generalized information
on the parameters ice drift during an ice
moving in the waters of the Gulf of Ob in Salmanovskaye
deposit area. For these conditions, we
have accepted to make water intake structure with
recessed filtering part and given idea about their ice
protection and proposed an effective design of protective
constructions for all possible effects of ice
hummocks. We have also given a description of bases
of technology of construction works the rationale
for the design parameters of facilities. In view of the
possible load, two rows of closed pile foundations are
provided for the protection of water receivers consisting
of bored piles and channel filtering grillage. In
the first row, near to the water receivers we have provided
metallic, lattice constructions from metal profile
pipes laid on the top of water receivers on the
grillage. The second row of protective structures
around water receivers was designed as a halfly indepth
monolithic reinforced concrete grillage of rectangular cross-section form with an ice pick from a
metal corner rental rendered monolithic on the outside
perimeter of the grillage. Concrete grating are
designed also to protect the gravity pipelines along
the borders. Rectangular grillages interconnected
with cross bar bonds witch are also made of reinforced
concrete. The proposed technical solutions
provide reliable protection against possible water
intake facilities including dynamic effects from windrowing
ice fields in the Far North. Options include
new constructions of underground horizontal and
channel filter water intake structures that could be
effectively used in such conditions
