In the article, we present existing approaches to the study of the optimal composition of technological systems. We have justified a new method of improving the reliability and the efficiency of technological systems of grain harvesting based on application of mass service theory. An engineering methodology for the substantiation of structure of the technological complex of agro-climatic conditions has been developed. In this case, the basis is the method proposed by S. D. Shepelev and G. A. Okuneva. To justify the structure of the technological complex of agro-climatic conditions of the Krasnodar region we have developed a mathematical optimization model, as criteria of which the losses from downtime of combine harvesters and transport vehicles have been taken. On the basis of the developed technique co-dependence on the number of combine harvesters «Torum-740» from the capacity of vehicles and coefficient for their use for the Northern zone of the Krasnodar region has been found
In the article, approaches to the management existing at the present stage are considered, their merits and disadvantages are described. General scientific and special approaches to management are singled out. The system, functional and process approaches are described in more detail. The principles of E. Deming are considered. It is pointed out that the application of the above approaches to production management is limited only by the economic sphere of activity, while there is a prospect of using these approaches in the field of labor protection. The article substantiates a selection of the process approach as the most promising in the management of the labor safety management system and health protection of a machine-building enterprise
The intense rhythm of people's lives in many countries has led to the need to develop and produce «fast food» products. They include dry breakfasts of a porous macrostructure in the form of rods, bars, and flakes, made from cereals, legumes, potatoes and dried fruits. Over the past 10 years, ready-to-eat foods that do not require heat treatment have become popular, the range of breakfast cereals has significantly increased, air grains, pads with filling, asterisks and rings have appeared. The global trend of consumption of slowly digestible carbohydrates predominates. Corn flakes and blown grain began to be used as supplements to soup instead of toast, served for tea and coffee. However, the problem of making and marketing specialized dry breakfasts has not yet been fully solved. The aim of the research is to expand the range of specialized dry breakfasts for people with high physical and mental loads. The tasks of modernizing technology and equipment for the production of dry breakfasts were solved. The methods of preparation for extrusion of easily oxidized in the air raw nuts were developed. Formulations of dry breakfasts for people with high physical and mental loads were developed. The objects of the research are analysis of existing technological schemes, grain, fruit and nut raw materials. We used classical methods of research to determine the composition of proteins, lipids and carbohydrates, as well as modern instrumental methods for assessing the qualitative composition of raw materials, semi-finished products and finished products. The research results include the modernization of technology and equipment for the production of breakfast cereals. Formulations of ready-made breakfast cereals with the addition of cereals, dry fruits and nuts have been developed, in order to improve the quality characteristics and nutritional value of the extrudates. The proposed technology and developed recipes are promising for introduction into production
In the author's interpretation we consider concepts and methods of science, such as science, knowledge, model, gnosticism and agnosticism, the principle of Ashby, facts, empirical regularity, empirical law, scientific law, and others. We have formulated the main problem of the science, concluding that cognitive abilities of a human are limited and do not provide effective knowledge in a very large volume of data. The solution to this problem is to look at ways of automation of scientific research. Traditionally, we use information-measuring systems and automated systems research (ASNI) for this. However, the mathematical methods used in these systems, impose strict impracticable requirements to the source data, which dramatically reduces the effectiveness and applicability of these systems in practice. Instead of having to submit to the source data impracticable requirements (like the normality of the distribution, absolute accuracy and complete replications of all combinations of values of factors and their full independence and additivity) automated system-cognitive analysis (ASC-analysis) offers (without any pre-processing) to understand the data and thereby convert them into information and then convert this information to knowledge by its application to achieve targets (i.e. for controlling) and for solution for problems of classification, decision support and meaningful empirical research of the modeled subject area. ASC-analysis is a systematic analysis, considered as a method of scientific cognition. This is a highly automated method of scientific knowledge that has its own developed and constantly improving software tool – an intellectual system called "Eidos". The system of "Eidos" has been developed in a generic setting, independent of any domain and can be applied in all subject areas, in which people apply their natural intelligence. The "Eidos" system is a tool of cognition, which greatly increases the possibility of natural intelligence, just like microscopes and telescopes multiply the possibilities of vision (but in this case only if you have this possibility). The study proposes a new view of the models: phenomenological meaningful model, which is currently represented only by systemic cognitive models, and which is currently in the middle between empirical and theoretical knowledge. The system called "Eidos" is considered as a tool of automation of the learning process, providing meaningful synthesis of phenomenological models directly on the basis of empirical data
Quality of seed material is defined by several
parameters which are: viability, growth force, energy
of germination and so on. But one of the most
important indicators is productivity. It is possible to
increase productivity of agricultural plants when
using various ways of preseeding processing. One of
ways of preseeding processing is ozonization. Thus, it
is possible to receive ozone and air mix by means of
various devices. One of the most effective ways of
receiving ozone is its synthesis in the field of an
electric discharge of an electroozonizer. But, at the
moment, in the world the set of designs and
modifications of electroozonizers is known. In this
regard, we carried out literary search, with the
purpose to define the most effective design of the
generator of ozone. We investigated various designs
of generators of ozone and their positive and negative
sides are given. On the basis of the carried-out
analysis it is established that the most suitable design
for receiving ozone at preseeding processing of seeds
is the ozonizer of lamellar type. But, despite
efficiency of application of a lamellar ozonizer, it is
necessary to achieve its stable work as preseeding
processing of especially small seeds demands
accurate observance of technological parameters
The article analyzes the ways of ensuring a stable
quality of vegetable raw materials in the process of
storage and use of biopreparations patented in Russia
and abroad. The search was conducted in the period
from 1995 to 2015 on the databases of the patent
agencies of the Russian Federation, the United States,
Japan and the European Patent Organization. We have
systematized the patented methods, the
implementation of which can increase the shelf life of
vegetable raw materials. The study led to the
conclusion of the usefulness of developing innovative
ways of ensuring a stable quality of vegetable raw
materials in the process of storage using
biopreparations
Expanding the range of flour confectionery products
for people suffering from intolerance to wheat protein
is relevant in the circumstances of import substitution.
The domestic market of gluten-free confectionery
products fully meets the demand of this category of
people, which are dominated by sweet tooth children,
requiring constant variety of confectionery. Therefore,
the purpose of the work, which consists in expanding
the range of pastry products based on buckwheat and
quinoa, is relevant. The study presents a shortbread
recipe based on buckwheat flour with different
dosages of quinoa, a block diagram of the production
and evaluation of the quality of the finished
confectionery. Sensory evaluation of quality was
carried out by a tasting analysis by a special system of
scores: quantified indicators of quality - color, taste,
smell, surface, shape and form in a break - is
presented in the form of balls, followed by
mathematical processing. We have defined physical
and chemical indicators of quality biscuits, including
moisture, alkalinity, absorption, fat and sugar content.
Based on the assessment of quality of gluten-free
shortbread we have set the optimal ratio of buckwheat
flour and quinoa is equal to 70:30. The developed
formulation will expand the range of gluten-free flour
confectionery and can be adapted to the process and the equipment installed on the existing confectionery
businesses
In this article, we have presented the study and
implementation of the physical model of
motion of two coupled pendulums with use of
numerical methods. When building the model
we were using the method of Euler solutions of
differential equations, which displays
pendulums visual motion, as well as building
graphics of functions of speed, angle and
acceleration depending on time with high
reliability. We have generated equation of
motion for generalized coordinates for the first
and second mathematical pendulum. The
generated application implements a physical
model of a double mathematical pendulum,
commit sustained oscillations with the ability
to change the basic parameters: deflection
angle, speed, mass and length of the rod in C++
language by programming environment
“Embarcadero RAD Studio”. This application
can be used as a model of a double
mathematical pendulum in the study of
oscillations, as a methodical manual and a
virtual laboratory in physics, informatics and
programming classes – for demonstration,
study and create applications in the objectoriented
C++ programming language
The designers of competitive seed-cleaning equipment face a crucial task to develop a rational technology of post-harvest seed processing, which would provide output of high quality certified seeds with minimal cost. For determining rational technology of post-harvest processing of sunflower seeds in the seed-cleaning machine based on the grain-cleaning unit ‘GCA-20’, we chose three existing technologies (without fractionation), with various combinations of grain-cleaning equipment, one fractional technology followed by separation of seeds into size fractions (Ø7-Ø8 mm, Ø8-Ø9 mm) on the photoelectron separator. The aim of the study was to determine the priorities of the promising option of post harvest processing by the method of priori ranking using a psychological experiment. According to the survey results, we calculated the coefficient of concordance. After the calculation of the coefficient of concordance its significance was determined using Pearson criterion with the number of degrees of freedom equal 4. The calculated value of Pearson criterion is 17.58, and the table value is 9,488. As the table value is less than the calculated value of Pearson's, we can argue with 95% probability that the opinions of the experts regarding the priority technologies are assessed by the coefficient of concordance and the consistency of the researchers is not accidental. After checking the coefficient of concordance on Pearson criterion a chart of ranking options was built. As a result of the psychological experiment there was determined the rational variant of the technology of post-harvest sunflower seed processing. According to this technology seeds need to be fractioned into two size fractions (Ø7–Ø8 mm, Ø8–Ø9 mm) on the photoelectron separator at the final stage of seed separation in seed-cleaning complexes. This technology will allow us to increase the output of high-quality seeds and reduce their content in the waste (85.52 to 65.60%)
A selection of food additives for the enrichment of
waffle products was made. Food additive "Powder
from tubers of Jerusalem artichoke" is distinguished by
a high content of inulin - 46.21%. Low-fat sunflower
lecithin contains a significant amount of phospholipids
(98.29%). The influence of the joint application of
food additives "Powder from the tubers of Jerusalem
artichoke" and nonfat sunflower lecithin on the
technological properties of the wafer test was studied.
It is established that the introduction of the food
additive "Powder from the tubers of Jerusalem
artichoke" together with defatted sunflower lecithin,
instead of the traditional soybean, allows to reduce the
viscosity of the wafer test. When introduced into wafer
dough, the dosage of defatted sunflower lecithin can be
reduced, compared to soybean, from 0.4 to 0.2% by
weight of flour
