USING CONVOLUTIONAL NEURAL NETWORKS FOR LICENSE PLATES RECOGNITION. ADVANTAGES AND DISADVANTAGES IN COMPARISON WITH TEMPLATE-BASED METHOD

abstract 1201606112 issue 120 pp. 1706 – 1715 30.06.2016 ru 268
Car license plates recognition problem is one of the typical tasks of computer vision. Video surveillance software usually provides license plates recognition function. Meanwhile, there are many approaches to solve this problem, where template-based methods are the most common. Such methods providing predictable and short enough execution time, and little percent of mistakes. However, such methods are far less effective in case there is a need to recognize car’s license plate, which may be located in unpredictable place, typed in undefined font and on non-standard background, or without strict formatting. For example, USA car license plates. One of the methods to increase effectiveness and quality of such license plates recognition is to use neural networks. It is assumed, that neural networks usage can significantly increase recognition quality. Nevertheless, neural networks usage entails difficulties of it’s training, and often becomes less efficient as template-based methods usage. This article discusses probability of usage of convolutional neural network, which was trained using MNIST (Mixed National Institute of Standards and Technology) database. This article is a review of usage of templates and neural networks for car’s license plate recognition in terms of quality, performance and complexity of the usage

Production and processing of grains formed in the national economic system of the country a number of cereals-governmental sectors, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and role of the grain as a commodity in the state economy can not be overestimated. This product, is totally liquid, which has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortagecovered by imports.According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of developing multicriteria economic-mathematical model of a comprehensive assessment of technology of cultivation of agricultural crops.

abstract 1131509119 issue 113 pp. 1683 – 1696 30.11.2015 ru 874
Grain is the strategic importance and is the basis for food security. The gross national product share of grain and its products is about 10-15%. It always stands out from other types of raw materials, as used to produce the most massive daily foods. When selecting cultivation technology agricultural crop agronomist has at its disposal a database of more than a hundred times-personal of alternative technologies for each crop. Prior to the decision-maker (DMP) is the task of specific criteria to select the most suitable for the owners, climatic zone of technology cultivating culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The possibility of developing a set of mathematical models and methods for multi-criteria analysis and assessment key technologies of cultivation of agricultural crops

PLANNING AND CALCULATION OF ORGANIC MINERAL FERTILIZERS DOSAGES IN FIELD CROP ROTATIONS WITH THE USE OF AUTOMATED INFORMATION SUBSYSTEM (BASED ON THE MATERIALS OF THE AGROINDUSTRIAL COMPLEX OF THE KRASNODAR REGION)

abstract 1461902013 issue 146 pp. 58 – 67 28.02.2019 ru 354
The problems of crop management and management decision support are still relevant at the moment. Crop production is of strategic importance and is the basis of our country's food security. The use of information technology in agriculture was limited to the use of computers and software, mainly for managing financial transactions and maintaining accounting and operational accounting. It should be noted that the measures taken to increase labor productivity and automate technological processes in the agro-industrial complex did not have an integrated nature; therefore, they slightly influenced the efficiency of the industry and, as a result, the competitiveness of products. Thus, the development and implementation of a computerized decision support system in crop management based on mathematical models for analyzing and evaluating the economic efficiency of crop cultivation technologies, crop rotation rationalization models, data analysis models of the book on crop field history, optimal selection of plant protection products and fertilizers highly relevant. This scientific project can be considered a priority and highly demanded, as contributing to the implementation of one of the requirements of the State program for the development of agriculture and regulation of the markets of agricultural products, raw materials and food of the Russian Federation for 2013-2020. The aim of the project is to improve the mathematical models and methods for managing technological processes at agricultural enterprises through the development and implementation of an integrated automated information system for crop management. The article is devoted to the theoretical substantiation and expediency of the practical implementation of the program module for solving the problem of planning and calculating the dosages of organic and mineral fertilizers in the field crop rotation of farms of the Krasnodar region, which is a part of the developed integrated automated plant management information system at agricultural enterprises

METHODS AND MEANS OF ESTIMATION EFFICIENCY TECHNICAL EQUIPMENT OF THE СО2-EXTRACTION SYSTEM VEGETABLE RAW MATERIAL

abstract 1321708110 issue 132 pp. 1355 – 1366 31.10.2017 ru 501
Modern extraction systems are characterized by a change in the parameters of the production cycle under the influence of a number of causes caused by the structural dynamics of systems. Information systems can successfully function by solving the tasks of collecting, processing, analyzing and distributing real-time information, which involves the use of modern information technology methods. With increasing requirements to the volume, speed and quality of information on the progress of extraction processes, modernization of information systems is required, allowing to make informed decisions by management structures. In the article the regularities of mass transfer of n-components in carbon dioxide of the solid-liquid system are considered. The effect of spontaneous interfacial convection in the mass transfer of individual components under the influence of an electromagnetic field of low frequency is detected. The joint mass transfer of extractive substances during spontaneous interfacial convection leads to an increase in the mass transfer coefficient of eugenol compared to its diffusion mass transfer
