PERSPECTIVE TECHNOLOGIES OF POSTHARVEST SUNFLOWER SEED PROCESSING
DescriptionThe 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%)

JUSTIFICATION OF SUNFLOWER SEED CLEANING SCHEME ON AIR-SIEVE GRAIN CLEANING MACHINES
DescriptionA set of actions aimed at preserving seed quality is the task of primary importance, which is expected to produce effective results. To implement this task it is necessary to prepare high-quality seeds by cleaning and sorting sunflower seeds on air-sieve grain cleaning machines. To determine the rational scheme of cleaning sunflower seed piles of the ‘Lakomka’ variety on the air-sieve grain cleaning machine ‘MVU-1500’ a qualitative analysis has been carried out. Cleaning sunflower seeds is carried out by an air stream by one or two sieves for separating large impurities and by two sieves, one of which separates milled seeds into the overseeding ,with the second dividing the whole seeds. In such a scheme of cleaning sunflower seeds, purity corresponds to the 3rd class of seed material and has some disadvantages. The disadvantages are as follows: the gathering seeds in sieve Ø5.0 have low individual weight and the sieves show low quality of work. To facilitate the work of the sowing sieves a grading sieve is installed, which will separate 50% of the seeds into the gathering. The size of the openings in the grading sieve is selected with the help of the correlation table. The sieve for sunflower seed variety ‘Lakomka ‘will be Ø 3.6, which will select the most valuable seeds with weight above 90 g from the purified material thus improving the productivity and performance of the sowing sieves. A promising scheme of cleaning sunflower seeds is the air flow rate equal to 4.43 m/s, with one grading sieve of Ø 3.6 and two sieves of Ø 7 and Ø 3.6 mm in grain cleaning machines that will allow you to get high quality seed material that meets the requirements of GOST(Russian national standard) for seed material

MODELING DEEP BAR INDUCTION MOTORS FOR SUGAR FACTORY ELECTRICAL POWER SUPPLY SYSTEMS
DescriptionThe article is devoted to solving the urgent task, which is improving the accuracy of transient simulation modes of power supply systems of sugar factories. The material of the article is exploratory in nature, manifested in the fact that we have studied various mathematical models designed for the analysis of symmetric modes of deep bar induction motors. A number of the provisions of article have scientific novelty, which lies in the approach to the choice of the coordinate system for modeling deep bar induction motors. We have formulated the requirements for transient analysis method for deep bar induction motor. We have developed the mathematical models of high-voltage induction motors in different coordinate systems for the analysis of steady-state and transient modes of operation. Based on double-circuit rotor model of induction motor, an analytical expression for the frequency characteristic of the deep bar induction motor is obtained. As an example, we have calculated and presented real and imaginary parts of the frequency characteristic of the induction motor type 2АЗМ-2000 with slip s = 1. The mathematical models of induction motors allow using mathematical apparatus more efficiently to explore different symmetrical modes of engines. The study proposed to use transients in the power supply systems of sugar factories for the analysis. The authors suggest an approach to modeling, which can also be useful for modeling induction generators

PHYSICAL MODELING OF ODOMETRIC COMPRESSION OF SAND
DescriptionThe odometric compression of sand with constant rate of loading (CRL) or constant rate of deformation (CRD) and continuous registration of the corresponding reaction allows to identify the effect of stepwise changes of deformation (at the CRL) and the power reaction (at the CRD). Physical modeling of compression on the sandy model showed the same effect. The physical model was made of fine sand with marks, mimicking large inclusions. Compression of the soil at the CRD was uneven, stepwise, and the strain rate of the upper boundary of the sandy model changed cyclically. Maximum amplitudes of cycles passed through a maximum. Inside of the sand model, the uneven strain resulted in the mutual displacement of the adjacent parts located at the same depth. The growth of external pressure, the marks showed an increase or decrease in displacement and even move opposite to the direction of movement (settlement) the upper boundary of the model ‒ "floating" of marks. Marks, at different depths, got at the same time different movements, including mutually contradictory. The mark settlements sudden growth when the sufficiently large pressure. These increments in settlements remained until the end of loading decreasing with depth. They were a confirmation of the hypothesis about the total destruction of the soil sample at a pressure of "structural strength". The hypothesis of the "floating" reason based on the obvious assumption that the marks are moved together with the surrounding sand. The explanation of the effect of "floating" is supported by the fact that the value of "floating" the more, the greater the depth

SYSTEM OF PATIENTS SUPPORT USING A DATA TERMINAL (ON THE EXAMPLE OF SMARTCITY COMPANY)
DescriptionIn February of 2016, the Russian Ministry of Health confirmed the guidelines on functionality introduction of medical information systems for medical organizations (MIS MO). The required MIS development levels (of basic and advanced functionality), the capacity status (required and recommended) and a set of subsystems were defined there. One of the subsystems is the "Information support of patients" and all of its functions, being advisory in nature, represent the advanced set of MIS functionality, namely: the support for information terminals and screens, as well as providing the patient or his legal representatives with the access to medical documentation and background information. However, the opportunity to make an electronic appointment to see a doctor on your own plays the leading role as the most widespread and socially oriented medical service. The research is concerned with the issues of the e-registry work support (ER) via the data terminal for patients, including printing the appointment tickets, made via the data terminal. The paper suggests a new patient oriented algorithm of the prompt way to make an appointment to see the doctor. The idea is simple – avoid a large number of clicks on the ER interface tabs and immediately suggest the most appropriate time of reception, basing on previous patient visits. The algorithm was tested on the infomat software, run by "Smartcity" in MO of Krasnodar Region and used to make the appointment to see a doctor by patients on their own, without any assistance of registry staff in MIS

CHRONOLOGICAL STUDY OF CONFIGURATION OF A WATER – BOILED PROTEIN SYSTEM WHEN DRYING
DescriptionThe article presents results of research on drying a slurry consisting of distilled water and finely chopped cooked chicken protein of table eggs. The suspension is placed in a Memmert oven, which has temperature of 60 °C. In the process of removing moisture when drying the slurry of water - boiled protein we examined kinetics of its drying and performed chronological photographing of conformation of the system of water - boiled protein. The final weight of the protein remaining after evaporation, was 0.06 g corresponding to 26% by weight of cooked protein source in an amount of 0.23 g. The analysis of the system appearance including the evaporation of the water showed that the protein was originally white, and this color does not undergo any changes until 35 minutes of drying, i.e. when the main base is water. Upon further drying of the suspension, starting with 40 minutes, boiled protein literally "melts" in the surrounding water residues; and as it is disappearing, becoming more and more transparent. Meanwhile, the forms of the protein are becoming round and transforming into the form of liquid crystals. The final phase of the protein is a solid transparent film

SYNTHESIS OF A SYSTEM OF OPTIMIZATION OF CONSUMPTION OF NONRENEWABLE RESOURCES
DescriptionThe NP-problem of discrete optimization of consumption of non-renewed resources is considered. The weights of edges of the graph of resources set cost of consumed resources. It is offered to use the transitions of discrete system conditions on the complete graph with number of vertexes, equal to quantity of discrete resources, for the problem decision. The purpose of such system is construction of a chain of the predetermined length and the minimum weight on the complete graph. The problem factor is factorial growth of number of variants of chains on graph at linear growth of quantity of resources. The main idea consists in a use of found statistical regularities of transition ranks of discrete system at construction of chains with the minimum weight on graphs of the any size. Use of ranks allows to abstract from concrete weights of transitions and to find the property inherent optimum. In this article, the structure of discrete system is presented and its functioning in a mode of analysis of ranged decisions is described. Distinctive feature of the presented system is use of the generator of ranks, the generator ranged chains and the statistics block. They are used for definition of distribution of suboptimum decisions. In addition, the article contains the description of structure and functioning of discrete system in a mode of synthesis of suboptimum decisions on the basis of the found distribution of probabilities of local decisions. Novelty of the offered approach to construction of solvers of NP-problems is in using empirical functions from ranks of local decisions to control the search
