Description
The article proposes to use the automated systemcognitive analysis (ASC-analysis) and its software tool which is "Eidos" system to solving multiparameter typing, system identification and cartographic visualization of spatially-distributed natural, environmental and socio-economic systems. Imagine, that we have an original point cloud with coordinates (X,Y,Z), each with known values of gradation descriptive scales of nominal, ordinal, or numeric type S(s1,s2,...,sn). Then the "Eidos" system provides: 1) building a model that contains generalized knowledge about the strength and the direction of the influence of descriptive gradations of scales at Z=M(S); 2) estimation of the values of Z for points (X,Y) described in the same descriptive scales S(s1,s2,...,sn), but not a part of the original point cloud; 3) a cartographic visualization of the spatial distribution of values of the function Z=M(S) for points outside the initial cloud, using Delaunay triangulation. Basically, this means that the "Eidos" system ensures recovery of the unknown function values on the grounds of the argument and implements it in a generic setting, independent of subject area. We propose a new scientific concept called "Geo-cognition system", which is defined as a software system that provides conversion of source data into information, and knowledge in visualization and mapping of this knowledge, resulting in the cognitive map becomes graphics. This feature can be used to quantify the degree of suitability of the watersheds for cultivation of certain crops, the evaluation of the ecological situation on particular territories on the structure and intensity of anthropogenic load, visualization of results of forecasting of earthquakes and other unwanted risks or emergencies, as well as for solving many other similar mathematical essence of tasks in a variety of subject areas. We have also shown a simple numerical example

THE METHODS AND THE RESULTS OF THE TESTING OF AN ASYNCHRONOUS GENERATOR WITH SIX PHASE ZONES
DescriptionThe article contain the peculiarities of testing asynchronous generator with sixzone winding on the basis of the asynchronous motor series 4A100S4 and analysis of obtained characteristics. Circuit parameters of the stator winding can significantly affect the characteristics of the asynchronous generator. Asynchronous generator was tested with a stator winding connected star, autotransformer and sectional winding. Use chastising windings opens the possibility of applying various circuits of capacitors and the load to asynchronous generators, which in turn affect the efficiency and stabilizing properties of the electric machine. Asynchronous generators to test with sectional winding by confirmation of theoretical calculations for determine the most optimal scheme under connect capacitors and load, testing the stator winding. The volume of testing for asynchronous generators standard is not defined, so we proposed testing method, taking into account the design features of the stator winding. Asynchronous generators were tested with the help of special equipment with the use of analyzer of energy power quality. Article contains characteristics of idling, short circuit and others, considered the heat mode. On the basis of the results we have determined the parameters of the circuit, the efficiency and power factor of induction generator

Description
The problem of availability and quality of medical care is a priority nowadays. The Medical Centres for Information and Analysis (MCIA) have been created in the regions for the purpose of gathering information about the quality of services rendered and subsequent data are transferred to the Ministry of Health Care of Russia. Regional MCIA are complex and developed systems that solve simultaneously many problems, one of which – the organization of collection, processing, recording and analysis of information on the provision of medicines. It has been established in the course of conducting an analytical review of examination systems of preferential recipes and information protection that the level of automation of routine operations of the MCIA activity of the Krasnodar Region is high, but there is no qualitative information processing. As a result of the comparative analysis it was determined that the automated review of medical prescriptions for privileged drugs allows identifying abnormalities in the reference data without any analytical conclusions about the causes and consequences of the case. Taking into account the fact that in the provision of essential medications there still exists quite understandable demand for software products which automize the routine work of specialists, it remains obvious that the directions of improvement of software products are not implemented fully. In this regard, the present research proposes measures to improve the existing systems by integrating with the information system of medical and economic control of the prescription of medicines

Description
Conditions in which the work of acoustic magnetic device proceeds are complicated because of the number of interconnections. Solving problems under such conditions analytically is difficult because of many variables and complexity of some dependencies. The article describes the conditions in which the work of acoustic magnetic device, designed for nonchemical treatment of hydroponic solution, takes place. The criteria, establishing the initial state of the chains, containing mutual inductance, are analyzed. The work establishes the criteria relating the physical parameters of the environment with the output parameters of the device. The similarity of conditions of heat transfer on the surface of the device is provided, and the relation of the scale of temperature and power lost when heating the ferrite and winding machine is determined. The criterion of the heat transfer process is defined. The criterion, determining the relation of the environment temperature to the thermal mode of the acoustic magnetic device, is defined. The criterion of the conditions at the boundaries of the system and cavitating liquid is determined. It is found, that the cavitation area appears in the technological volume of liquid at the work of acoustic magnetic device. The criterial equation for geometric parameters of different types and constructions of the acoustic magnetic device is defined. In accordance with the task based on the third theorem of similarity, the group of criteria that provides the similarity of the model to the proposed original by all existing indicators, is selected

METHODS OF CHOOSING DIAGNOSED VEHICLE PARAMETERS IN AGRICULTURE
DescriptionThe article presents an analysis of the existing approach to automobiles technical maintenance in agriculture. We have pointed out that in modern conditions it is impossible to forecast the automobiles maintenance operation frequency and as a result its improvement as well. It is obvious that one cannot achieve the considerable increase of maintenance operation efficiency by separate means and there exist the necessity to treat it as a system and use the up-to-date methods to investigate and improve complicated systems. We have made a conclusion that the increase of maintenance operation efficiency is not possible without some rational strategy of maintenance operation and repair. We have shown that the program of maintenance operation and repair being an integral part of automobiles technical maintenance has considerable effect on maintenance and repair quality. As a result, there is some necessity of the developed system of parameters diagnosing and control in technical maintenance and repair. We have shown that to get sufficient diagnose information one needs selection of the controlled parameters which give maximum information about the object technical status taking into account possible characteristics of its operational faults. We have discovered that in order to solve the task it is necessary to have the object’s information pattern, calculation of possible characteristics of the controlled object being in good or bad order due to some parts fault, evaluation of information brought by every parameter and determining parameters to be diagnosed. We have proposed to evaluate the parameters’ information value with the help of information entropy as uncertainty measure that is one of the main concepts of the information theory. Because of solving the task, we have got the aggregate of the controlled automobile parameters orderable according to the amount of information

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

Description
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
