HOW TO SOLVE THE TASK OF CLASSIFICATION OF TYPES OF RIFLE AMMUNITION USING THE METHOD OF ASCANALYSIS

abstract 1171603055 issue 117 pp. 841 – 875 31.03.2016 ru 540
In forensics there is an urgent need to determine the type of rifle (automatic, rifle, large caliber pistol) depending on its used ammunition found at the scene of the use of weapons. We offer a solution to this problem with the use of new innovative method of artificial intelligence: automated system-cognitive analysis (ASC-analysis) and its program toolkitwhich is a universal cognitive analytical system called "Eidos". In the "Eidos" system we have implemented the software interface that allows posting of images and identifying their outer contours. By multivariable typing, the system creates a systemic-cognitive model, the use of which, if the model is sufficiently accurate, may be helpful in solving problems of system identification, prediction, classification, decision support and research of the modeled object by studying its model. For this task the following stages: 1) input images of ammunitions into the "Eidos" system and creation of their mathematical models; 2) the synthesis and verification of the models of generalized images of ammunition for types of weapons based on the contour images of specific munitions (multiparameter typing); 3) improving the quality of the model by separating classes for typical and atypical parts; 4) quantification of the similarities-the differences between specific types of munitions with generic images of different types of ammunition of the weapon (system identification); 5) quantification of the similarity-differences between types of ammunition, i.e. cluster-constructive analysis of generalized images of ammunition. A numerical example is given. We also possess a successful experience of solving similar problems in other subject areas

STATISTICAL METHODS OF EVALUATING THE LEVEL OF THE DRUG ADDICTION DISTRIBUTION IN THE RUSSIAN FEDERATION

abstract 1171603064 issue 117 pp. 1004 – 1014 31.03.2016 ru 481
The problem of drug addiction in the Russian Federation poses a threat to the national security. For effective decision-making in the field of drug prevention and fight against drugs, it is necessary to assess the drug situation, the state of law enforcement practices and socio-economic development of the observed areas. The article describes the method of complex statistical evaluation of the level of drug addiction in the Russian Federation. Based on a systemic approach author distinguishes stages of multivariate statistical analysis of a priori indicators characterizing the state of socio-economic, demographic, biomedical and law enforcement situation in certain areas of the federal districts of the Russian Federation. The classification of signs into factorial indicators groups is proposed. Estimations of relationships studied statistics and draw conclusions about the impact on the drug situation of various factors, including the average for the group, are presented. Then this paper describes the application of the factor analysis to construct regression models to predict the drug situation in the Russian Federation according to the status of independent indicators and trends in the integrated development of regions. A method for evaluating the level of development of the drug situation in the Russian Federation because of automatic classification algorithms is proposed and the principle of its application is proven. The results of the classification of the federal districts of the Russian Federation on the level of the drug situation are given

TECHNICAL AND ECONOMIC PERFORMANCE OF VM32 MACHINE MULTI-COMPLEX

abstract 1171603073 issue 117 pp. 1129 – 1138 31.03.2016 ru 364
The article describes problems of economic growth of the Russian Federation, development of high-tech knowledge-intensive manufacturing industries on the basis of a fundamentally new technological order, creation and development of import-substituting production of engineering resources that relate to dual-use technology and are in the most demand by strategic organizations of machinetool, machine-building and military-industrial complexes (aircraft engineering, rocket and space engineering, shipbuilding and power engineering). We proposed some measures to improve the accuracy in the manufacture of complex and large-sized parts with weights up to 100 tons. Precision machining of the workpiece surface is directly dependent on the tooling, quality and quantity of the cutting tool (CT), as during the processing the CT wears and must be replaced. We have described the modernization of multi-machine complex and ways of increasing the accuracy, the change in the kinematics tool supply to increase the number of tools used in the processing. We made calculations of the new chain drive of the tool supply. The proposed modernization of the tools will increase the instrument amount that allows increasing the accuracy of manufacturing products. We have also made calculations of the economic effects of the tool supply modernization

OPTIMIZATION OF WELL PLACEMENT IN WATERFLOOD PROJECT IN "X" FIELD NIGER DELTA, NIGERIA

abstract 1171603090 issue 117 pp. 1370 – 1381 31.03.2016 ru 581
Water flooding used in secondary oil recovery to level up reservoir pressure can be enhanced in order to fit the reservoir conditions with the aim to optimally recover oil. One of the important optimization variables to realize this aim is optimal well placement. Various methods have been suggested for this problem. Among these is direct optimization, although accurate, is difficult due to the number of simulations required. Optimal placement of up to six injection wells was studied at the X field in western Niger Delta of Nigeria. Injection rate and injection time was also optimized and net present value (NPV) of the flooding project was used as the objective function. In this case study, it is shown theoretically and by means of Eclipse 100 that according to the basic elementary reservoir characteristics, optimal oil recovery is strongly dependent on well placement pattern and injection rate. Simulation results show that good sweep efficiency can be achieved with a regular pattern with an optimal well position

ADAPTIVE SYNTHESIS OF INTELLIGENT MEASUREMENT SYSTEMS WITH THE USE OF ASC-ANALYSIS AND "EIDOS" SYSTEM. SYSTEM IDENTIFICATION IN ECONOMETRICS, BIOMETRICS, ECOLOGY, PEDAGOGY, PSYCHOLOGY AND MEDICINE

abstract 1161602001 issue 116 pp. 1 – 60 29.02.2016 ru 1438
The article proposes using the automated system-cognitive analysis (ASC-analysis) and its software tool, which is the system called "Eidos" for synthesis and application of adaptive intelligent measuring systems to measure values of parameters of objects, and for system state identification of complex multivariable nonlinear dynamic systems. The article briefly describes the mathematical method of ASC-analysis, implemented in the software tool – universal cognitive analytical system named "Eidos-X++". The mathematical method of ASC-analysis is based on system theory of information (STI) which was created in the conditions of implementation of program ideas of generalizations of all the concepts of mathematics, in particularly, the information theory based on the set theory, through a total replacement of the concept of “many” with the more general concept of system and detailed tracking of all the consequences of this replacement. Due to the mathematical method, which is the basis of ASC-analysis, this method is nonparametric and allows you to process comparably tens and hundreds of thousands of gradations of factors and future conditions of the control object (class) in incomplete (fragmented), noisy data numeric and non-numeric nature which are measured in different units of measurement. We provide a detailed numerical example of the application of ASC-analysis and the system of "Eidos-X++" as a synthesis of systemic-cognitive model, providing a multiparameter typization of the states of complex systems, and system identification of their states, as well as for making decisions about managing the impact of changing the composition of the control object to get its quality (level of consistency) maximally increased at minimum cost. For a numerical example of a complex system we have selected the team of the company, and its component – employees and applicants (staff). However, it must be noted that this example should be considered even wider, because the ASC-analysis and the "Eidos" system were developed and implemented in a very generalized statement, not dependent on the subject area, and can successfully be applied in other areas
