THE SYNTHESIS OF SYSTEMIC-COGNITIVE MODELS OF THE INFLUENCE OF ENVIRONMENTAL FACTORS ON THE QUALITY OF LIFE OF THE REGION

abstract 1341710001 issue 134 pp. 1 – 13 29.12.2017 ru 119
The article describes the synthesis and verification of statistical and system-cognitive models of the influence of environmental factors on the quality of life of the population of the region. This stage of the ASC-analysis is performed in the system called "Eidos". As a result, we have created and validated (verification stage) all the specified systemic cognitive models. It is expected that reliability for the models of knowledge is sufficiently high for a given subject area, that is why we can state the discovery of a dependence of life expectancy and causes of death from environmental conditions. Typically, knowledge models are approximately 20% higher in accuracy than statistical models, which operate on the principle of positive pseudo-prediction. Making decisions based on the model of Abs (matrix of absolute frequencies) is not appropriate because of the different number of instances of classes (generalized categories) and dependence of the solutions of this amount. In the model called Prc2 (conditional and unconditional percentage distribution) the dependence of the model values of the number of examples in classes has been removed, but the accuracy of it is usually same low as in the Abs. In addition, for decision-making based on this model, one has to compare the values of conditional and unconditional probabilities manually, which is laborious and hardly possible for large dimensional models. The knowledge model called Inf3, based on a measure similar to the Chi-square, is the result of the automated comparison of values of conditional and unconditional probabilities presented in the model of Prc1, which is similar to Prc2, and usually has a fairly high accuracy, especially considering the high complexity of the subject area, which we simulated. Therefore, in accordance with the technology of the ASC-analysis data conversion into information, and afterwards - into knowledge, it is the model of Inf3 which is planned to be used for the solution of problems of identification, forecasting, decision-making and exploring the modeled subject area, through the study of its models

REGULARITIES OF DEFLECTION IN THE DIAGONAL AND RADIAL TIRES OF THE GRAIN COMBINE PROPULSIONS

abstract 1341710014 issue 134 pp. 164 – 173 29.12.2017 ru 80
The aim of the study is to investigate the regularities of deflection in the diagonal and radial tires for the grain combine propulsions of high productivity. The research method is experimental. The "tire tester" and specially designed devices for revealing the deflections of the inner and outer tube relative to the rim in the circumferential and radial directions have been used. The outcome indices of the pneumatic-tired wheel are determined with the tire capability to deflect so, that at low - hysteresis losses in the rubber-cord casing and its acceptable tensions, based on a resource, the largest area of contact with supporting base would be created. This circumstance acquires the particular significance developing tires for grain combines of high performance, the deflection regularities of which are poorly studied at present. The analysis of experimental studies showed the feasibility of using the grain combine propulsions instead of the diagonal radial tires of the same size. The resistance to rolling of radial tires 30.5 R-32 is lower than in diagonal tires 30.5 L-32, and the developed contact area due to the increase of length is higher, which reduces sealing effect on the soil

abstract 1341710016 issue 134 pp. 189 – 204 29.12.2017 ru 139
Development of infrastructure of Sochi as mountain resort has demanded increase in transport means of communication and development of territories, difficult for construction. Construction works cover territories of the Kudepsta and Adler districts and also Krasnaya Polyana. The main problems at design near Greater Sochi are landslides and landslide processes and also high seismicity of territories. Besides, the increased technogenic loadings on many sites have led exogenous processes to activization. At unforeseen activization of landslide processes it is required to develop actions for strengthening of the existing constructions or construction of new protective designs in the shortest possible time. However, there are problems of modeling of a landslide situation. On the example of construction retaining at the portal constructions of a railway tunnel near Sochi modeling of landslide processes on the basis of natural observations (monitoring) is considered and also actions for stabilization of slope processes are described

LED LAMPS FOR IRRADIATION OF GLASSHOUSE PLANTS

abstract 1341710022 issue 134 pp. 263 – 272 29.12.2017 ru 31
At present, much attention is paid to the production of domestic vegetable products. One of the main reserves of increasing the yield of vegetables is the production of products in sheltered ground. The intensive construction of new glasshouses and greenhouses complexes has sharply increased the demand for engineering facilities, with the help of which an artificial microclimate is created in the structures of the protected soil. To create high irradiations, a very significant specific installed power of photosynthetic radiation sources is required. Currently, advanced greenhouse plants use LED irradiation. The experience of these farms showed that LED irradiators have a number of significant advantages over discharge lamps: a significantly lower specific power of the irradiator; the service life of LEDs is several times higher; they do not contain toxic substances (mercury); LEDs are powered from a low voltage network, which is significant from a safety standpoint. Isolation of greenhouse plants from the effects of natural factors of the environment leads to undesirable consequences. The deficit of the amount of natural energy of optical radiation penetrating the structures of protected ground in modern industrial greenhouses during off-season is eliminated by additional artificial radiation from greenhouse lamps. In this case, the emission spectrum of lamps differs significantly from the natural one. This is especially true for ultraviolet radiation. The issue of creating an LED lamp for its application in structures of protected ground is considered. The main requirements for the creation of a photosynthetic lamp on the spectral composition of radiation are given. The necessity of a long-wave ultraviolet component in the emission spectrum of a lamp is substantiated

abstract 1341710027 issue 134 pp. 328 – 338 29.12.2017 ru 28
The technology of cultivation of most crops provides pre - and post-emergence weeding of crops, and their feeding with the availability of soil nutrients. According to the used underlying technology, these operations are performed separately. The harrowing of crops after germination is necessary for weed control, the destruction of the soil crust for access of air to the root system and partial thinning of dense crops. Further destruction of weeds on crops are herbicides, high-quality entry which provide sprays. The latter can provide small and ultra-low volume spraying in high performance and environmental requirements. However, separate execution of technological operations for fertilizing and harrowing reduces the quality of work, increases the cost of production. The proposed combination of technological operations on a harrowing of crops different crops simultaneously with feeding plants solid mineral fertilizers. The combination of technological operations for one pass of machine-tractor unit in the field provides a reduction of the fleet, its capital intensity, the energy, cash costs, and hence competitiveness of products. The studies proposed new technical support processes, technological scheme of the multifunctional unit to combine the operations of feeding and harrowing of crops

abstract 1341710036 issue 134 pp. 438 – 449 29.12.2017 ru 24
In the dairy industry, the segment of yoghurts and yoghurt drinks is one of the most dynamically developing. Competition contributes to the production of high quality products. The transition to market relations encourages producers to use new prescription ingredients in the production of various yoghurts. In addition, it is essential to improve the existing ones and create qualitatively new technologies of products with a directed change in the chemical composition. Sour-milk drinks not only satisfy the physiological needs of the body, but also have a preventive and therapeutic purpose. Utilization of these products contributes to the prevention of numerous diseases, as well as life prolongation and increase of working capacity. The dietary properties of sour-milk drinks are determined by the presence of “live” beneficial microflora and persist for a long time, as long as this microflora remains viable and pure. The article contains data distinguishing the effects of the use of commercial fermentation starters EKOKOM Laktina, TM GoodFood, Kaprina on the qualitative characteristics of dairy clots. The article specifies the influence of fermentation starters and vegetable fillers on the organoleptic parameters of the final sour-milk product.
