Augmented reality offers unique ways to display visual
information, in particular the visualization of threedimensional
objects. With AR object can be visualized
directly in the context of its operation. As an example
can be a piece of furniture rendered in the interior, plants
in the garden, the architectural object in the landscape.
Modern consumer devices such as smartphones and
tablet computers, as well as the algorithmic base lead to
the possibility of augmented reality mass usage. The
concept of augmented reality offers a better user
interface for visualization through a combination of
methods of controls and visualization. The camera angle
can be controlled by user’s head or device movements,
which is intuitive and efficient. Method of visualization
of three-dimensional object by combining its image with
the surrounding environment allows better perceiving
the object, its dimensions, and material properties. In
contrast to the traditional visualization approaches, AR
does not require modeling of the environment. Objects
visualization by means of AR can be applied to customer
decision support while buying products. The user is
provided with the ability to visualize an object in interior
or outdoors, where he plans to place it, and interactively
examine the object from any angle. This article attempts
to systemize possible options for interaction with
potential buyers through applications with augmented
reality technology
Tracking is a vast field of research associated with
navigation, robotics, and virtual environments (virtual
reality). Tracking for augmented reality requires higher
level of precision, increased range of action, as well as
work with a wider variety of input data. It is important
that augmented reality technology requires tracking in
real time, which also complicates the task. Correct
visualization of objects in three-dimensional space
requires six degrees of freedom tracking: three position
values (x, y, z) and three angles (rotation around the
respective axes) to determine the orientation. To solve
this problem, different approaches and sensor types are
being used. In this article, we present a brief history of
the development of tracking technology and analyze the
current approaches to implement the process of tracking
on mass mobile devices such as smartphones and tablet
computers. We also describe some issues in
implementing optical marker based tracking for
visualization of large scale models
The article presents a comparative assessment and
peculiarities of nuclear magnetic relaxation
characteristics of rapeseed and sunflower lecithin. It
was established, that lecithin’s nuclear magnetic
relaxation characteristics, namely, protons’ spin-spin
relaxation time and amplitudes of nuclear magnetic
relaxation signals of lecithin components, depend on
content of oil’s fat acids and phospholipids, contained
in the lecithin. Comparative assessment of protons’
spin-spin relaxation time of rapeseed and sunflower
lecithin components showed, that for their
identification protons’ spin-spin relaxation time of the
lecithin’ first component at 40°C and 60°C
temperature, when differences in values of protons’
spin-spin relaxation time of the sunflower and
rapeseed lecithin’ first component are most obvious,
should be used as an analytical parameter.
Comparative assessment of amplitudes of proton’s
NMR signals of sunflower and rapeseed lecithin
components showed, that relations, established earlier
for sunflower lecithin between mass share of
phospholipids (substances insoluble in acetone) and
the sum of amplitudes of proton’s NMR signals of the
third and fourth components, cannot be applied to
rapeseed lecithin; that is for the development of an
express method for determination of mass share of
substances insoluble in acetone (phospholipids) in
rapeseed lecithin, it is necessary to carry out additional
research with the purpose of clarifying the mentioned
relations
The article presents a method of engineering
calculation of the strength of band saws and belt force
to stabilize the cut
Based on the Karman vortex theory, the calculated
dependences for velocity induced by profile action in
the flow, lifting force and drag force, acting on the
profile, are determined. Calculations, performed in
MathCAD, allowed, for the given up-stream velocity,
to calculate height of mid-section of the bed-formation
profile, width of the profile along the chord, span of
the profile, angle of attack, velocity of the induced
flow. For the calculated profile parameters, the
velocity circulation value, drag force and lifting force
are determined. As the bed-formation profiles, it is
recommended to use flat plates, frame constructions
with transverse ribs in the form of arch, fish-like
symmetric or slightly curved profiles. Ways of the
profile installation in the flow, depending on the angle
of attack, are evaluated: three versions - for symmetric
profiles, and six versions - for asymmetric profiles.
Diagram of the device for the hydrosystem tailrace
protection against erosion is developed on the basis of
submerged NACA 0302 profile or profile of

To study the formation of plunge basin in the
Cheboksary hydroplant, we used a scale model of the
spillway dam and all structures in the tailrace, installed
in the slot flume. When we passed the flow
corresponding to the diversion flow of the hydroplant
with a glance to the modeling scale, it was found that
the plunge basin was formed behind the end fixing of
the spillway apron. To research the dynamic facilities
of hydrosystem tailrace protection against erosion, we
used a small glass flume with a model of the roundcrested
weir. For the experiment, the water-surface
elevations were built in the flume without the weir,
and the uniform motion area was established. In
MathCAD software environment, the curve of the flow
of measuring rectangular weir of the flume was
created. Because of measurements, the curve of water
surface by the flow motion through the round-crested
weir was made. As the main criterion for modeling, the
criterion of Froude was selected. Scale of modeling of
flow parameters was determined. For testing, models
of hydrodynamic profile and sail structure with streamforming
sluice valves were built. The process of sand
washout from the flume bottom and formation of the
bottom ridges when installing the profile was
photographed. Impact of the profile on the flow and its
relation with the formation of the bottom topography
were studied. Full-scale values of geometric
parameters of the bottom ridges and their movement
velocity were established as well

Lecithin and sorbitol tristearate (Radiamuls Sorb
2345K) are the emulsifiers used in the manufacture of
chocolate products. The effects of various blends of
lecithin and Radiamuls Sorb 2345K when added in
concentrations up to 14 g / kg on the rheological
properties of molten dark and milk chocolate were
determined by rotational rheometry. The results show
that regardless of the total amount of emulsifier, yield
strength, both dark and milk chocolate most effectively
reduced by applying a mixture of approximately 30%
lecithin and 70% RADIAMULS SORB 2345K.
Regardless of the concentration of the emulsifier
proportion RADIAMULS SORB 2345K in the mixture
can be reduced to 25% without a significant increase in
equilibrium viscosity milk chocolate. With respect to
the total emulsifier dosage in the range of 4 to 6 g / kg,
the lowest values were found for the viscosity of the
mixture letsitin- Radiamuls Sorb 2345K 50:50 for dark
chocolate and milk chocolate to 75-25, respectively.
when using the mixture of lecithin-SORB
RADIAMULS 2345K there are various possibilities
for adjusting the rheological properties of chocolate,
confectionery coatings and fillers on fat basis. The
results obtained show that the confectionery mass flow
can easily be adapted to the specific processing needs,
thereby improving product quality and production
efficiency increases
