Algorithm for the formation of a scene for visualizing data for HT-devices
Authors: Voronin A.V.
Published: November 2021

Data visualization through the formation of a scene on the screen of a Hi-Tech- (HT)-device is increasingly attracting the attention of specialists in the field of computer science and software. This is due to the fact that the visibility of the visualized information is important not only for users of HT-devices (a person perceives 80% of information visually (with the eyes)), but also for analytics of decisions made based on the analysis of the visualized data. At the same time, there is a steady tendency in the world to increase the volume of visualized data, and the resource of its perception by a human is limited. The use of the patterns of visual perception of objects associated with the properties of the «golden» section allows one to formulate a visualization criterion for visualized data, and, consequently, an algorithm for the formation of a scene for visualizing data for HT-devices. The purpose of the study is to determine the visualization criterion for visualized data and, based on it, the algorithm for the formation of the data visualization scene, as well as the features of the algorithm functioning. The visualization criterion for visualized data is determined through the coefficient of coverage of the screen area. The optimal value of the coefficient corresponds to the mathematical definition of the «golden» section. As a result of the study, it is necessary to highlight the definition, based on the analysis of the properties of the «golden» section, of the visualization criterion for data visualization, the algorithm for the formation of the data visualization scene and the features of its functioning. The practical value of the results lies in the fact that the proposed criterion represents a mathematical interpretation of the «golden» section property for visualizing data on modern HT-devices of various sizes.
Analytical prediction of the integral risk of violation of the acceptable performance of the set of standard processes in a life cycle of highly available systems Part 1. Mathematical models and methods
Authors: Nistratov A.A.
Published: November 2021

With the widespread adoption and development of the process approach, it became clear that the standard processes used in the life cycle of highly available systems undoubtedly have a cumulative impact on risks that arise. However, the possibilities for predicting risks in practice are significantly limited: private and integral risks of violation of the acceptable performance of implemented processes, estimated by simplified methods, do not reflect the real picture, and specialized models of specific systems and processes require painstaking and long-term scientific and methodological study. Thus, there was a critical methodological contradiction between objective needs and real capabilities in predicting private and integral risks. Carrying out a scientific search for ways to eliminate the identified contradiction, the main goal of this work (in two parts) is to create scientifically based methodological and software-technological solutions for analytical prediction of the integral risk of violation of the acceptable performance of a given set of standard processes in the life cycle of systems. In the first part of the work, for 30 standard processes defined by GOST R 57193 (characterized by typical actions and real or hypothetical input data for modeling and linked to possible scenarios for their use in the creation and/or operation and/or disposal of systems), mathematical models and methods for predicting the integral risk of violating the acceptable performance of a given set of standard processes with the possibility of traceable analytical dependence on influencing factors are proposed. The second part of the work is devoted to the description of the proposed software-technological solutions for risks prediction using models and methods of the first part for solving practical problems of system engineering.

Published: November 2021

The design of technological processes for the manufacture of gas-dynamic supports (GDO) of gyroscopes is traditionally based on the use of finishing operations with the use of free abrasive. This leads to a high complexity of manufacturing such devices and complicates mass production. Reducing the labor intensity is possible when the labor-intensive finishing operation with a more productive operation of honing the holes of the GDO is replacing. But such a replacement requires the development of high-precision technology, which implies mathematical modeling of the process of honing the holes of GDO gyroscopes made of ceramic CM-332. Objective – a mathematical model of the process of honing the holes of GDO gyroscopes made of ceramic CM-332 is developed, which allows for the known shape of the workpiece, the tool used and the technological modes to calculate the geometric shape of the processed hole, and the value of any error. A mathematical model of honing of precision holes of GDO gyroscopes is developed, which takes into account the main factors of the process, the characteristics of the tool and the technological modes of processing. The dependence of the accuracy of the geometric shape of the processed hole on the characteristics of the tool is determined. The use of the results of the study made it possible to reduce the labor intensity of finishing operations for processing GDO holes by 10-15 times in the conditions of mass production of gyroscopes.

Published: November 2021

Off-grid Photovoltaic (PV) system along with battery storage is very effective solution for electrification in remote areas. However, battery capacity selection is the most challenging task in system designing. In this study, an off-grid PV system along with battery storage is designed for the remote area of Karachi, Pakistan. The system is designed by considering the maximum energy requirement in summer season. The battery storage is selected to fulfill the energy demand during the night and cloudy seasons. On the basis of load, a total of 6 kW system is required to fulfill the energy demand. For such system, 925 Ah of battery is required to meet the energy requirement for a day in absence of solar irradiation. A regression-based correlation between battery capacity and energy demand is prepared for suitable battery sizing using Minitab. An economic analysis of the project is also carried out from which a net present value and simple payback are determined as USD 10,348 and 3 years, respectively. The environmental benefits are also been determined. It is found that the system will reduce around 7.32 tons of CO2 per annum which corresponds to the 183.69 tons of CO2 not produced in the entire project life.

Published: November 2021

Milk-containing products occupy a large place in the range of popular products. Replacing milk fat or protein with vegetable fat can reduce the biological value of the product and its organoleptic properties. the effect of direct application starter cultures on raw materials that use functionally necessary ingredients (structure-forming agents, salt, sugar, etc.), food additives (thickeners, stabilizers, preservatives, etc.) and a variety of non-dairy components (non-dairy fats, non-dairy proteins, meat products, fruits, vegetables, spices, herbs, nuts, etc.) is ambiguous. The paper deals with the use of homogeneous and combined starter cultures in the production of fermented milk products from natural and normalized milk and milk-containing mixtures with a substitute for milk fat. The introduction of components of plant origin into the product leads to a decrease in the content of milk protein in the mixtures, which in turn leads to the formation of clots with a non-uniform consistency. Slow acid formation in milk-containing mixtures indicates a decrease in milk sugar in them with this type of normalization in fat, relative to the normalized milk according to the classical technology. This pattern was revealed both when using starter cultures on lactic acid thermophilic streptococci, and on combined starter cultures. In this paper, it is proposed to use Streptococcus salivarius subsp in ferments for milk-containing mixtures. thermophilus strain ST-95. The introduction of the ST-95 strain into the starter culture made it possible to obtain from the milk-containing mixture a fermented milk product with well-pronounced organoleptic properties, a stable clot structure and sufficiently high taste properties. The greatest positive effect was obtained on combined ferments.

The main task of animal husbandry is to obtain large volumes of products: increasing the weight gain of cows and milk yields in a short time at minimal cost. The existing feeding standards for cattle are based on the use of Class 1 feed. In farms, most feed contains a low concentration of nutrients, the feeding of which does not allow to maintain the standard ratio of the diet. The quality of milk is not only of economic importance, which determines the profitability and competitiveness of dairy products in the market, but also of social significance, which is associated with the impact on human health. The most important factor determining the quality of milk and its suitability for further processing is the fullness of animal feeding: the energy value of the feed ration, the ratio of basic nutrients. The article presents data on the effect of the feed additive "Furor" based on fulvic acid, developed by LLC "Esson", which.

The article presents the results of experimental research on the development of a formulation and technology for the industrial production of kumis drink enriched with an iodine-glycoside complex, which is a source of molecular iodine with antioxidant activity. Study of the iodine level in patients with tuberculosis showed the following results: iodine deficiency was diagnosed in 86,7% of the total number of examined patients - the median ioduria in this group of patients ranged from 20 ?g/l to 99 ?g/l. The article describes a technology of production of kumis drink enriched with iodine-glycoside complex, including following operations: acceptance and preparation of raw materials; normalization and preparation of the mixture; pasteurization, homogenization, cooling and insertion of "iodine-glycoside"; preparation of the fermentation culture; fermentation and souring, bottling, maturation of the drink; packaging, labeling and cooling. It also includes the results of evaluating the organoleptic indicators of kumis drink - consistency, taste, color, smell and appearance, as well as the physical and chemical parameters: weight fraction of fat, protein, dry fat-free substances; the volume of settled whey, antioxidant balance in respiratory pathology by activating the KEAP1 /Nrf2 /ARE redox-sensitive system inducing the gene expression that control the endogenous antioxidants synthesis. Binary complex (kumis drink + molecular iodine) is considered here as a non-pharmacological pathogenetic agent. The technological process of the production of a functional product with anti-tuberculosis activity ensured the preservation of the physical and chemical parameters of the kumis drink, reducing the titratable acidity to 44,8% in the iodine-enriched drink against 57,6% in the control sample. The author elaborates on mechanisms of the participation of the “iodine-glycoside complex” and low-molecular organic substances, in particular, the amino acids of the kumis drink, in the regulation of pro-, with pleiotropic properties for the treatment and prevention of tuberculosis.

In solving the problem of vegetable protein deficiency, triticale grain is of great interest – a unique hybrid that com-bines the best hereditary qualities of wheat and rye. The protein content of triticale is 1.0 – 1.5% higher than that of wheat and 3–4% higher than that of rye. Obtained a new variety of grain triticale – "Slide". Products prepared from this grain crop have a high nutritional value, since the protein that is part of triticale is characterized by an increased content of essential amino acids, and is not inferior to wheat grain in terms of the content of macro – and micro-elements. It contains a lot of copper, phosphorus, potassium, magnesium, calcium, sodium, zinc, manganese and iron, as well as vitamins В9, В5, В1, PP and E. Information about thermal characteristics as functions of tempera-ture plays a key role in engineering calculations and mathematical modeling of the processes of drying and heat treatment of triticale grain. The method of nonstationary thermal regime, based on the solution of the problem of thermal conductivity over two temperature-time points, developed by B.C. Wolkenstein, was used to determine the thermophysical characteristics. The determination of the thermophysical characteristics of the grain was carried out on the Kossfield RT 1394 N measuring unit (National Instruments). Revealed the character of the dependence of diffusivity, thermal conductivity and specific heat capacity on temperature. Equations describing the thermophysi-cal characteristics of grain at a humidity of 13.57 and 21.83% in the temperature range of 20–100 оС are obtained

Published: November 2021

The hardware design of the rectification unit for the production of isopropylbenzene in the presence of the AlCl3 catalyst is considered, the use of which has a number of problems associated with its corrosiveness, rapid deactivation, the complexity of regeneration, etc. One of the possible solutions to the listed technological disadvantages is the use of heterogeneous zeolite-containing catalysts. In this case, during the reconstruction of the existing production of isopropylbenzene in the technological scheme of separation of alkylate, three rectification columns are released, which are expediently used to separate the alkylate of ethylbenzene production. To study the possibility of using the discharging distillation columns, a computational experiment was carried out using the Honeywell UniSim Design modeling system, in which a model of the alkylate separation unit for ethylbenzene production was formed. The NRTL method was used as a mathematical package for calculating the thermodynamic properties of the mixture components. As a result of modeling the operation of the alkylate separation unit for each distillation column, the optimal operating process parameters were obtained: pressure of the top and bottom of the column, reflux ratio, temperature profile along the height of the column. The calculated material balance of the technological scheme shows that in the first distillation column, complete separation of benzene from the alkylation reaction mass is achieved, the second column ensures the production of commercial ethylbenzene, and in the third column, a fairly clear separation of diethylbenzene from the remaining components of the mixture is obtained. The performed computational experiment showed that for the organization of the stable operation of the technological scheme for the separation of alkylate in the production of ethylbenzene, it is possible to use all the considered distillation columns without changing their design parameters at a load on the reaction mass of alkylation of about 60 t / h.

Published: November 2021

In recent times, new anti-adhesion devices including devices based on carboxymethyl cellulose (CMC), which have “barrier” effect are being developed and actively introduced into surgical practice. The “barrier” should be completely resorbed after the time required to healing the morphofunctional integrity of the injured peritoneum, be economically available and easy to use (including laparoscopic technologies). But the time when the CMC is in the body is insufficient to prevent the formation of adhesions, particularly in the presence of non-absorbable rigid implants. The reactive functional groups in CMC allow to transform the CMC-macromolecule into a spatial structure. For this are required the using of bifunctional (bicarboxylic or aminocarboxylic) acids and the transform of a part of the carboxyl groups from the Na-form to the hardly soluble H-form, i.e., it is necessary to crosslink CMC-macromolecules. Adipic acid and glutaric acid, aminoacetic acid and amino capronic acid used are linking agents. The influence of modification parameters on the degree of polymers swelling in water is studied. As a result, to obtain membranes designed for the treatment of adhesive disease, it is recommended to use additives in CMC of bifunctional compounds.

The competitiveness of rubber membranes determined by their durability, quality, reliability, including the time required to create. During operation, the membranes undergo complex deformations, as a result of which a large number of potential destruction zones of a different nature arise, which can lead to the failure of the product. The standard test methods used in the development of formulations for membranes involve testing the material under uniaxial tension conditions in most cases and do not take into account the actual loading conditions of the product during operation, which significantly increases the development time of new formulations for membranes. The paper presents and applies in practice a computational and experimental method of analysis the complexly stressed state of rubber membranes, including carrying out simple laboratory tests in a heterogeneous complexly stressed state, which is realized during the operation of rubber membranes, and analyzing the stress-strain state by the finite element method. An inhomogeneous complexly stressed state was realized by forcing the rubber membrane with a spherical indenter. The application of a computational-experimental method for analyzing the complexly stressed state of rubber membranes is considered on the example of a rubber corrugated membrane of an automatic valve of a bag filter purge system. An assessment of the physical and mechanical properties of rubbers in a heterogeneous complexly stressed state was carried out, as well as an analysis of the stress-strain state of the membrane when it was loaded with a spherical indenter, which made it possible to identify the most dangerous zones of the section. The complex use of this method made it possible to improve the resource of this corrugated membrane by thirty five percent in comparison with the standard, while reducing the creation time.

In the Tambov region, due to the widespread introduction of promising technologies for growing sugar beets, its yield has significantly increased, at the same time, the used seeding machines are not always able to provide the required depth of planting seeds, which leads to loss of yield and difficulty in applying fertilizers. In the course of previous studies, it was determined that with an increase in the angle of the scraper over 60 degrees, an increase in the percentage of filling the cells of the disc with seeds in various hybrids occurs, so research has established that in the hybrid PMC-120 at an angle of installation of the scraper of 70 degrees, 100 percent of the cells are filled with seeds, while in hybrids XM-1820 and Troika, the cells were filled only by 93.3%. It should also be noted that the PMC-120 hybrid with a scraper angle of 70 degrees had the lowest damage to the pellets - 0.67%, while the XM-1820 and Troika hybrids had 0.83 and 0.73%, respectively. With an increase in the angle of installation of the scraper over 80 degrees, the percentage of damaged seeds increased from 0.4 to 0.66%, on the basis of this, the design of the seeding device was proposed and theoretically substantiated, a feature of which is the reverse rotation of the seeding disc, while the rear wall of the opener is made in the form of a parabola appropriate trajectory of movement of seeds, which ensures their distribution in the immediate vicinity of its rear wall, thereby reducing the risk of falling asleep to the bed of the furrow before the granules get there. It has been determined that the trajectory of the granule movement directly depends on the angular speed of the seeding disc, which in turn depends on the geometric characteristics of the cells of the seeding disc. It is theoretically substantiated that the speed of the seed in the disc cell is determined by the sum of the projections, which makes it possible to calculate the curved surface of the opener.

The development of resource-saving technologies for obtaining pure sea buckthorn oil and its compositions with other vegetable oils from dried crushed sea buckthorn cake is an urgent task. Sea buckthorn oil and its mixtures are obtained by extraction and simultaneous heat exposure, electrophysical methods of the process intensifying being considered in this case. Currently, there are no reliable data on the thermo- and electrophysical properties of dried crushed sea buckthorn cake at atmospheric pressure in the literature. Therefore, experimental studies of the thermo- and electrophysical properties of dried crushed sea buckthorn cake in a wide range of changes in state parameters are of great importance for solving theoretical and practical problems. The nature of the change in the specific heat, thermal conductivity and thermal diffusivity in the temperature range 20 ... 80 ° C and humidity 7.0 ... 17.5% was determined to be linear. In this case, the specific heat and the coefficient of thermal conductivity increase with increasing temperature while the coefficient of thermal diffusivity decreases. The nonlinear dependence of the dielectric loss coefficient on moisture was found to be due to a variety of forms of moisture binding in the sea buckthorn cake particles. It is obvious that with an increase in the cake temperature and humidity, the dielectric loss coefficient monotonically nonlinearly increases in the range of 0.46 ... 9.72. Empirical equations that make it possible to reliably determine the value of the specific mass heat capacity, thermal conductivity coefficients, thermal diffusivity and dielectric losses of dried crushed sea buckthorn cake from temperature and humidity in the range of 7.0 ... 17% with respect to absolutely dry matter were obtained as a result of studies of thermo- and electrophysical properties..

Increasing the yield of juice and biologically active components from plant raw materials is an urgent task in the production of functional beverages. For this, fruit, berry and vegetable pulp was treated with enzymatic preparations of pectolytic action and the yield of juice was determined. Samples of pulp of each raw material were treated with enzyme preparations: Fructocyme P6-L, Fructocyme P, Fructocyme MA, in an amount of 0.03% of the pulp mass. Enzymatic hydrolysis was carried out at 50 °C for two hours, after which the amount of obtained juice was compared with the control sample. As a result, when adding Fructocyme MA to the pulp of apples and carrots, the juice yield increases by 8% and 17%, respectively. When Fructocyme P6-L is added to the pulp of kiwi, blueberries, grapes, the juice yield increases by 6%, 12 and 10%, respectively. To determine the effect of enzyme preparations on the yield of biologically active components, the previously selected enzyme preparations were added to all samples in an amount of 0.01; 0.03; 0.05; 0.07% of the pulp mass, and the total content of polyphenols was determined by colorimetry and anthocyanins. As a result of the experiment, it was found that in terms of the amount of polyphenolic substances extracted from the pulp, fruit and berry raw materials can be divided into three groups: raw materials with loose pulp, with pulp of medium density and raw materials with dense pulp. As a result, individual enzyme preparations and optimal modes of application were selected for each type of raw material. The dependence of the content of polyphenolic compounds on the dosage of the addition of enzyme preparations has been established.

One of the most effective and cost-effective ways to provide the population with important nutrients is the fortification of mass-consumption products. Bakery products are products of regular consumption in the diet. An integrated approach to solving the problem is provided through research in the design of prescription formulations and technologies of new types of bakery products, including through the use of non-traditional vegetable raw materials. Recipes and technology of preparation of samples of wheat bread with apple pomace replacing part of wheat flour with buckwheat (the first sample of bread) and rice flour (the second sample) are developed. The technological parameters of cooking hearth bread, in a non-paired way, have been developed. The influence of buckwheat and rice flour on the duration of the technological process of bread preparation is investigated; the influence of the introduced food additives on the organoleptic and physico-chemical indicators of bread quality is determined; a comparative assessment of the content of mineral compo-nents in the developed and control samples is shown. The use of secondary apple raw materials (fresh-frozen apple pomace), buckwheat and rice flour as non-traditional components in the technology of bakery products allows you to get a product with high organoleptic properties and a rich mineral composition. Studies of the effect of food additives on the organoleptic parameters of the bakery product allow us to make a conclusion about the pronounced effect of the added ingredients on the appearance, color and condition of the crumb. However, these additives do not lead to a change in the taste and smell of baked products. Analysis of the chemical composition of the developed samples of wheat bread showed that the content of iron and phosphorus in them exceeds the value of the control sample by many times.

Published: November 2021

Ethanol produced from various biobased sources (bioethanol) has been gaining high attention lately due to its potential to cut down net emissions of carbon dioxide while reducing burgeoning world dependence on fossil fuels. Global ethanol production has increased more than six-fold from 18 billion liters at the turn of the century to 110 billion liters in 2019 (1,2). Sugar cane and corn have been used as the major feedstocks for ethanol production. Lignocellulosic biomass has recently been considered as another potential feedstock. This paper reviews recent developments and current status of commercial production of ethanol across the world. The review includes the ethanol production processes used for each type of feedstock, both currently practiced at commercial scale and newly developed technologies, and production trends in various regions and countries in the world.

Fault identification is one of the most significant bottlenecks faced by electricity transmission and distribution utilities in developing countries to deliver efficient services to the customers and ensure proper asset audit and management for network optimization and load forecasting. This is due to data scarcity, asset inaccessibility and insecurity, ground-surveys complexity, untimeliness, and general human cost. In view of this, we exploited the use of oblique UAV imagery with a high spatial resolution and a fine-tuned and deep Convolutional Neural Networks (CNNs) to monitor four major Electric power transmission network (EPTN) components. This study explored the capability of the Single Shot Multibox Detector (SSD), a one-stage object detection model on the electric transmission power line imagery to localize, detect and classify faults. The fault considered in this study include the broken insulator plate, missing insulator plate, missing knob, and rusty clamp. Our adapted neural network is a CNN based on a multiscale layer feature pyramid network (FPN) using aerial image patches and ground truth to localise and detect faults via a one-phase procedure. The SSD Rest50 architecture variation performed the best with a mean Average Precision (mAP) of 89.61%. All the developed SSD based models achieve a high precision rate and low recall rate in detecting the faulty components, thus achieving acceptable balance levels of F1-score and representation. Finally, comparable to other works in literature within this same domain, deep-learning will boost timeliness of EPTN inspection and their component fault mapping in the long - run if these deep learning architectures are widely understood, adequate training samples exist to represent multiple fault characteristics; and the effects of augmenting available datasets, balancing intra-class heterogeneity, and small-scale datasets are clearly understood.
