In the present article, a technique for studying the
influence of the parameters of a drying plant on the
optimization criteria is described. The design of a
laboratory plant for drying bee-bread is presented. An
adequate empirical dependence of the effect of the
parameters of the process under study on the residual
moisture of bee-bread is established. An optimal
combination of factors has been revealed, which
makes it possible to minimize the residual moisture
of bee-bread
In many applications, we study the time series (or a
random process), which is the sum of the periodic
deterministic function of time and random errors that
distort the periodic signal. It is required to estimate
the length of the period and the periodic component.
It does not assume that the periodic function is
included in any parameter family of functions, such
as finite sums of sines and cosines. It is obvious that
the assumption of occurrence of a periodic function
in parametric family does not meet the
characteristics of the real world, ie, is conditional,
internal mathematical (look for the keys under the
lamp because there is a light, not in the bush, where
lost, because there are dark). For similar reasons, it
is impossible to assume that the distribution function
of the random errors is included in any parameter
family of distributions. In accordance with the new
paradigm of mathematical statistics in this article we
studied the problem of nonparametric estimation
(minimum) length of the period and the periodic
component of the signal. On the basis of natural
variation and scope of indicators is suggested a new
class of nonparametric estimators of the length of the
period and the periodic component in the time
series. Based on the general results of statistics of
objects of non-numeric nature we proved the
consistency of these estimates. From the practical
point of view it is necessary to minimize the
numerical (one parameter - ability length of period
of time) one or more of the 66 functionals, described
in the article
The article presents results of research of rotary-screw
systems in relation to the creation of rotary kilns for
the annealing of-cuttings in the preparation of cement
clinker. Using the proposed design, in comparison
with known designs of similar purpose, it significantly
improves performance, reduces size and power consumption
through the use of rotary screw systems in
the form of screw rotors and drums made hollow with
sidewalls assembled from separate strips or plates of
different geometrical shapes with form inside the
screw breaks or smooth edges, screw surfaces and
screw grooves. It is shown that the housing of the rotary
kiln is expedient to produce helical surfaces whose
centers of curvature are located within the housing.
Using the proposed constructions rotary kiln during
the firing when preparing cement wedge can increase
the speed of rotation of the housing, furnaces 5-10
times due to changes in the rotary-screw systems increase
efficiency and reduce the size of furnaces
In this article the model and a calculation procedure of
an integrated indicator of risk of the internal
environment of the integrated production system are
described. Then the steps of creation of triangular
fuzzy number for expected value of profit are given.
At creation of this fuzzy number the concept of an
indicator of risk of the internal environment of the
integrated production system was used. Further on the
basis of the developed model of internal risk the
interval model of efficiency of the integrated
production system is developed and described. In this
article the structure of a production chain of the
integrated production system of agroindustrial
complex was considered. In technologically complete
production chain, as a rule, allocate three stages – raw
materials production, storage and conversion, sale of
finished goods. Each subsequent stage depends from
previous stage, and at each stage various situations of
risk are shown. Also the process of risk identification
of the internal environment of the integrated
production system was considered in this article.
Process decomposition is executed, the description of subprocesses is given. For a risk assessment of the
internal environment it is necessary to know quantity
of production chains, and also to calculate value of risk
for each production chain on the enclosed algorithm.
Also in the article the principle of recognition and
interpretation of results of calculation of an integrated
indicator of risk of the internal environment of the
agro-industrial integrated production system on the
basis of Harrington's scale and standard indistinct 01
classificators is shown
The article defines the acts of corruption as a factor affecting
the external security of the country, given the
scope of public relations, which are affected by corruption.
We have displayed historical overview of corruption.
On the example of the recent political events in the
world, the article shows a destructive impact of corruption
on the constitutional arrangement of a number of
near countries and far abroad. The work defines the effective
role of the psycho-physiological study of polygraph
in detecting accuracy of information in the fight
against corruption in the Russian Federation. The use of
polygraph to improve anti-corruption policy of the state
opens up new possibilities in the fight with the worldwide
scourge of corruption. The work gives basic preventive
function to psychophysiological research on polygraph
in the organizations fighting against corruption in
Russia. The article analyzes the draft law "On the application
of the polygraph in the Russian Federation", which
is currently being introduced in the State Duma. Based
on the study of the projected rate, we have made conclusions
about the need for research on a polygraph in detecting
corruption risks in the case of appointments of
civil servants from the activity of which depends on security
and international prestige of the Russian Federation
The relevance of the theme of this article determines the fact that in modern conditions the sphere of housing and communal services, on the one hand, requires the immediate carrying out of complex modernization of communal infrastructure, and on the other hand, it has every reason to become a breakthrough for sustainable development of the domestic economy. The main elements of management in the sphere of housing and communal services the article defines the housing Fund, as well as many institutional agents engaged in its operation. It is established that housing and functioning municipal infrastructure have a significant physical and moral deterioration. Its presence negatively impacts on the quality provided to the population for consumption of housing services. We have identified the most significant factors and the degree of their influence on the development of innovative potential of the sphere of housing and communal services. The article substantiates the necessity of accounting these factors when developing economic and mathematical models for institutional agents of housing and communal services to make optimal decisions in conditions of uncertainty and enabling them to improve the quality of housing and communal services. Features of formation of economic-mathematical models were taken out of the scope of this article. We have defined a number of the most promising areas for carrying out of complex modernization of communal infrastructure of housing and communal services on the basis of introduction of new economic mechanisms, economic-mathematical models and instrumental methods that increase the quality of housing and communal services
Techniques of value analysis and "Direct-costing" are
well-known and popular. The ideas and principles of
value analysis and the method of "Direct costing" are
very similar, if not identical. On the one hand, these
ideas are very reasonable, well grounded theoretically
and proved its effectiveness in practice. On the other
hand, the wide use of these methods is hampered by
the difficulty of obtaining large amounts of detailed
technological and financial-economic information, as
well as the need for careful research by competent
professionals, well-versed in substantive subject area.
This is the contradiction between the desire to apply
the methods of the value analysis and "Direct costing"
and difficulty to perform it in practice. This
contradiction constitutes a real problem and may often
be discouraging and frustrating. In this work, we
propose a simple and effective solution to this
problem, theoretically well-informed with all the
necessary methodological and software tools and
widely and successfully tested in practice. The
proposed solution is based on two simple ideas: 1)
instead of collecting and holding a meaningful large
amount of technological and financial-economic
information we might apply approaches, pleasant
management theory; 2) to create systems for
automated control of natural and financial-economic
efficiency of expenses we might use the automated
system-cognitive analysis and its software tool – an
intellectual system called "Eidos". In the name of the
specialty 08.00.05 – Economics and national economy management, there are such words: "management of
enterprises, branches, complexes, innovation." The use
of the term "Management" implies that there is a
model that reflects the influence of factors on the
object of control, and there is the management system
making decisions based on this model. However, as a
rule, the dissertations in this field have nothing of this,
except only financial and economic calculations. The
article proposes an approach based on the control
theory, removing this disadvantage

Strategically significant dealings of bussines entities’ amalgamation and absorption are revised in the article. It presents the methods and information supply of the evaluation the business entity’s potential and the evaluation of potential increment of a business entity as a result of integration
While mechanical harvesting of potatoes, about
20-40% of the tubers get damages. Dynamic
loads, injuries of the tubers, causing internal
damage – which is browning of the flesh of the tuber, which occurs in the process of its storage.
At the same time, ways to express control of
damage to potato tubers will allow both
reducing damage during harvest, and promptly
sending damaged potatoes for recycling before
the results of mechanical stress for the tubers
during harvesting. The definition of internal
damage to the potatoes is possible because of
the analysis of the different elasticity of the
tissues of damaged and undamaged tubers. The
value of overpressure of the device is chosen
such way that during deformation of tubers
there mainly has been compression of the
damaged tissues of the tuber, with the least
turgor. The degree of damage of samples of
tubers is determined by the ratio of the volume
of damaged tissues of tubers to the total volume
of the sample. We have given the mechanical
properties of tissues of tubers, fruits and root
vegetables, their structure, dimensional
characteristics, it can be assumed that the use of
this method of determining internal damage
possible for apples, carrots, beets and harvest of
other crops. Use of damage control will enable
timely identification of hidden damage and
make it possible to eliminate their causes,
which lead to increase loss products
