THE USE OF LINEAR CELLULAR AUTOMATON AS A FORECASTING TOOL FOR STOCHASTIC SYSTEMS AFFECTED BY VARIOUS FACTORS

abstract 1531909010 issue 153 pp. 112 – 121 29.11.2019 ru 12
In the process of formation of nonlinear dynamics, the scientific society was able to refute the classical mechanisms of Newton-Laplace by justifying the chaotic nature of the phenomena of the world. However, despite the emergence of new mathematical models and tools, forecasting of nonlinear systems is a difficult task, as not only the quantitative and qualitative characteristics of the factors affecting the system are unknown, but also there is a problem of a small amount of information for forecasting. In this article, the authors consider the linear cellular apparatus as a tool for prediction the final state, to which the system will come based only on its output indicators of previous years. Since the use of a linear cellular automaton for prediction of nonlinear systems is an assumption of the authors, it should be tested on the series of stochastic systems exposed to different risk factors, which together give either a positive response of the system or a negative one. An example of such series is the time series of yields, as it is affected by climatic conditions, the appearance of which, in turn, is also difficult to predict. Prediction of stochastic systems using linear cellular automaton really makes it possible to get adequate and visual models. Due to the fact that the forecast model has a discrepancy with the real result of 0-15% (both positive and negative), the conclusion is that the predicted value will help either to take measures to ensure that the real value in the future is not lower, or to make sure that the decisions and measures taken are correct, when a value is higher than the forecast

METHODS OF CONSTRUCTING EFFICIENT ALGORITHMS BYPASSING BLOCKING ACCESS TO WEB-RESOURCES BASED ON HTTP TUNNELS

abstract 1531909025 issue 153 pp. 240 – 256 29.11.2019 ru 12
At present, the problems of blocking network traffic in computer networks, in particular, in the global Internet, are becoming increasingly topical. Understanding blocking mechanisms, opening new opportunities to circumvent such protection will give us, on the one hand, both new methods and methods of protection against unwanted blockages, and the vector of development of funds, in fact, stopping unwanted traffic, obstacles passing through network nodes. The article proposes an approach to effectively bypass access restrictions to websites based on HTTP tunneling with minimal costs, combined with the approach used in peer-to-peer networks. A description of the algorithm and its key features. A new approach has been introduced in the task of ensuring the accessibility of websites, which has several advantages and eliminates the disadvantages of existing solutions in the form of anonymous networks - the use of special node solutions and a strong dependence on the number of nodes in the anonymous network. The level of development of modern network infrastructure, the transition of society and most of human civilization to the information-network existence dictates new requirements for technical means of monitoring and analyzing network traffic. That, in turn, requires the development of new approaches to solving relevant problems

IDENTIFICATION OF PYRICULARIAORIZA ECAV. PATHOGEN AND REVEALING EFFECTIVE RESISTANCE GENES IN RICE GROWING DISTRICTS OF THE KRASNODAR REGION

abstract 1541910005 issue 154 pp. 34 – 44 30.12.2019 ru 12
The article presents results of studies on the intraspecific structure of the population of blast causative agent using sets of tester varieties from International Rice Research Institute - IRRI. The differentiation of the fungus population on tester varieties is the most progressive, since it allows one to determine the virulence genotypes of races of pathogens and identify the resistance genes of rice plants effective for them. The work has studied the diversity of blast causative agent in released rice varieties by morphological and cultural traits. Currently, in the world, the resistance of rice plants to blast is becoming one of the important indicators of the competitiveness of varieties. The basis for the successful rice breeding for resistance to blast is the availability of source material with a fairly wide spectrum and a high level of resistance. Resistance donors are selected based on the identification of genes that control this trait in rice

MINIMIZATION OF RESOURCE COSTS IN THE DISTRIBUTION OF PRODUCTION TASKS OF A COMPANY TAKING INTO ACCOUNT ITS STRUCTURE

abstract 1541910030 issue 154 pp. 317 – 326 30.12.2019 ru 12
The problem of the optimal distribution of production tasks is one of the important problems of effective planning of processes associated with production at the enterprise. However, the classical approach to solving this problem becomes of little use when the individual stages of the production process are performed sequentially and in the case when it is necessary to take into account the structural features of the technological processes of the enterprise. Purpose of work: to develop a methodology for minimizing costs in the distribution of production tasks, taking into account the structural features of the technological processes of the enterprise. We built a multicriteria discrete optimization model for the distribution of production tasks according to the structure of production elements. One of the methods based on the proposed model is proposed, which allows to identify groups consisting of four elements in the production structure of the enterprise. The model is built using a network design which are pre-fractal graphs. The use of pre-fractal graphs allows you to naturally represent the structure of production and technological links of the elements of the production system of large enterprises. The results of the work is the developed effective methodology for solving the problem of the network distribution of production tasks, taking into account the structural features of technological processes at the enterprise, the economic effect of which is to minimize resource costs. Based on the constructed model, we can develop automated means of monitoring and managing the production processes of a company

ALGOLOGICAL MONITORING OF VARIOUS TECHNOLOGIES OF MAIZE CROPS PRODUCTION

abstract 1552001006 issue 155 pp. 86 – 98 31.01.2020 ru 12
The article studies species composition and abundance of soil algae under hybrid Krasnodar 292 AMB cultivated with various technologies. 7 species of cyanobacteria and 11 soil algae were revealed. It was revealed that the highest total amount of algae was observed in variants of environmentally acceptable and intensive technology, which is associated with the positive effect of mineral fertilizers and the consequent application of organic matter on soil algal flora. However, in these variants a decrease was observed both in the number of species and in the abundance of green and yellow-green algae. The species Botrydiopsis arhiza Borzi was absent or found in insignificant amounts. The species composition was less diverse, which can be attributed to the negative effect of the herbicide used in these technologies. The method of tillage had practically no effect on green, yellow-green and diatoms. An increase in the intensity of soil cultivation had a significant negative effect on both the species composition and the number of cyanobacteria

STUDYING THE EFFECT OF PROTECTED AMINO ACIDS, LYSINE AND METHIONINE ON MILK PRODUCTION AND HEALTH OF HIGHLY PRODUCTIVE COW

abstract 1552001016 issue 155 pp. 207 – 232 31.01.2020 ru 12
The article discusses the relevance of the use of protected amino acids (lysine and methionine) in animal husbandry of the Krasnodar region, using the example of the farm "Krasnodar". The highest milk yield was obtained from cows with the combined addition of lysine and methionine in their diet. In relation to control (CR), the average daily milk yield in the group with combined additives (CR+L+M) was 38.4 kg/day. In addition, there was a positive effect of lysine and the combined additive (CR+L+M) on protein and fat in milk. Protected methionine (CRM) had no effect on the yield of fat and protein in milk. It was noted that additives of protected amino acids in groups with lysine and combined amino acids reduced the cost of dry matter (DM) and metabolizable energy (ME) per kg of milk. The results of our studies have shown that the productive milk response and its components are affected by the amount of the first limiting amino acid in the diet. Also, the supply of protected lysine changed the plasma concentration of animals and improved the availability of amino acids for milk protein synthesis
