DATA MINING OF USERS' SOCIAL NETWORK PROFILE FOR DETERMINATION OF TYPOLOGY OF THE CONSUMER. Part I

abstract 1071503107 issue 107 pp. 1638 – 1660 31.03.2015 ru 1400
The article considers a new approach to the definition of the type and psycho type of consumer - social network user, using psychographics methods, data mining and statistical techniques and analytical tools. In the study, we executed testing of respondents in order to identify the properties of their socio-economic preferences. Experimental and research work aimed at solving the problem described in the article, was divided into several complementary to each other and interconnected parts. The article presents the first part of the work, which includes the decision of 3 objectives, namely to obtain quantitative, statistical data on the properties of consumer preferences of users of the social network "VKontakte"; identifying groups of consumers with different severity of socio-psychological properties of preferences; definition of psycho type of user with a set of inherent characteristics and behavior patterns. To achieve the objectives we developed comprehensive software, called "MindScore", with main components at this stage - 1) the module for user authorization through the app of social network "VKontakte" and for extraction data of its social profile, 2) the module for processing and analysis data. In the study we have given rise to the creation of unique algorithms for personality mining using dataset of user profile social network

PHYSICAL MEANING OF CERTAIN SIMILARITY CRITERIAS OF TRANSPORT PROCESSES IN THE DESALTING CHANNEL THE ELECTRODIALYSIS DEVICE WITH ELECTROCONVECTION

abstract 1051501051 issue 105 pp. 845 – 864 30.01.2015 ru 1244
The phenomenon of electro convection in membrane systems is of considerable interest, because it is, according to many authors, the main mechanism of overlimiting mass transfer. A great number of theoretical and experimental works, in which, as a rule, dimensional values were used, are devoted to electro convection study. Because of that, in actual fact, there is investigated the influence of individual factors on the transfer process. For example, the influence of voltage jumps, the average speed of a forced stream of the solution, the geometric characteristics of the channel, the initial concentration, etc. However, the influence of these factors appears not separately, at the same time. Thus, there is the problem of introducing dimensionless complexes of dimensional values that have a physical meaning and that allow to evaluate the inner links of the process. As it is known, for solving that problem, there is applied a theory of similarity, based on the transition towards dimensionless parameters in equations and formulas describing the process, and using values, typical of the system under study. This work is devoted to the determining of physical meaning of similarity criteria of salt ions processes, taking into account electro convection in the desalting channel of electro dialysis apparatus. The channel is bounded with perfectly selective, homogeneous anion-exchange and cation-exchange membranes. The introduced similarity criteria are used so as to conduct the theoretical study of the effect of a number of parameters of a desalting process on electro convection

SYNTHESIS, VERIFICATION, AND THE STABILITY RESEARCH OF THE SYSTEM-COGNITIVE MODEL OF PROCESSING COMPLEX REGION

abstract 1011407016 issue 101 pp. 305 – 333 30.09.2014 ru 1189
In this article, in accordance with the methodology of SC analysis, we consider particular implementation stages of the synthesis of the numerical model and its analysis. We have also presented the results of the determination of the different states of the processing complex function of various factors on these states and their classification, as well as semantic networks and cognitive class diagrams and factors. On the basis of the analysis we made specific findings and recommendations for decision making at the management level of the region. After execution of the stages of cognitive structuring and formalization of the subject area the further stages of automated SC analysis have been accomplished, the first of which is the phase of the input database of precedents. All these steps are performed directly using "Eidos" universal cognitive analytical system

A MATHEMATICAL MODEL OF OPTIMIZATION OF THE VOLUME OF MATERIAL FLOWS IN GRAIN PROCESSING INTEGRATED PRODUCTION SYSTEMS

abstract 1001406017 issue 100 pp. 315 – 337 30.06.2014 ru 1238
The article suggests a mathematical model of optimization of the volume of material flows: the model for the ideal conditions; the model for the working conditions; generalized model of determining the optimal input parameters. These models optimize such parameters of inventory management in technology-integrated grain production systems, as the number of cycles supply, the volume of the source material and financial flows. The study was carried out on the example of the integrated system of production, processing and sales of wheat (bread) with the full technological cycle
