CONSTRUCTING A MATHEMATICAL MODEL OF PRICING FOR REAL ESTATE IN KRASNODAR

abstract 1311707098 issue 131 pp. 1181 – 1191 29.09.2017 ru 392
This study proposes a method of determining the cost of 1 sq. m. apartment on the example of Krasnodar, which is especially important in connection with the necessity of reliable and valid assessment of the property value in a modern market economy. We have performed an analysis of data on apartments in Krasnodar from the site of the Regional Energy Commission - prices and tariffs department of the Krasnodar region. We have also had an exploratory analysis of available data on the subject of emissions and insignificant data (by constructing line graphs and scatter plots); we have also checked for possible dependencies between observations and between variables (built correlation matrix). We have selected variables is linear, the regression model for the variable "cost of 1 sq. m the total area, ths. rub. "(multiple regression). Using regression analysis as a method of mathematical statistics we have revealed a form of analytical dependence of the result of the predictor variables and the degree of this dependence

DEVELOPMENT OF AN EXPERT SYSTEM FOR DIAGNOSIS MALFUNCTIONS OF ENGINES OF DIESEL POWER STATIONS

abstract 1141510032 issue 114 pp. 435 – 455 30.12.2015 ru 1366
The article considers development of expert system based on semantic networks for diagnosis malfunctions of the diesel power stations engines. The method allows developing expert systems via objectoriented programming language. The expert system allows to identify the problem without involving additional staff: at the start and overheats of the engine, when there is low power, with decreasing pressure etc

IMPROVING THE QUALITY OF EDUCATIONAL PROCESS THROUGH THE IMPLEMENTATION OF "SOCIAL NETWORK OF EDUCATION" SYSTEM

abstract 1181604076 issue 118 pp. 1202 – 1212 29.04.2016 ru 647
The article considers problems of the exchange of information between teachers, students and departments of educational institutions. It analyzes the advantages and disadvantages of traditional approaches: email, chat via phone, social networks. The questions of placement of information to large numbers of users were revealed. We also revealed the need to address issues related to the publication of major events, administrative announcements of educational institutions, which are visible to all users, and are assigned to a specific date. We suggested an approach to the publication of the activities of the individual system modules. The article shows a mechanism of mass mailings, providing users the ability to transmit information to two or more recipients and to ensure the exchange of information that is available only to send the recipient, as opposed to the "wall". We found an approach to increase the quality of the educational process, allowing rapid exchange of information between staff, students and departments of educational organization on the example of the system "Social network educational organization." In the approach, it has been proposed to take the ideology of social networking and project it on the specifics and needs of educational institutions, which will allow rapid exchange between staff, students and divisions (departments) educational organization. The study analyzed data on the age of users of the system over a period of 30 days

INCREASE OF QUALITY OF EDUCATIONAL PROCESS BY INTRODUCTION OF THE SYSTEM OF "ELECTRONIC TIMETABLE" IN AN EDUCATIONAL ORGANIZATION

abstract 1171603056 issue 117 pp. 876 – 888 31.03.2016 ru 721
Questions of placement of information on the website of the educational organization on the example of the educational timetable are considered. We have analyzed advantages and disadvantages of traditional approach. Questions of planning of the timetable of part-time teachers are considered. The article offers an approach to increase the quality of the organization of educational process allowing placing and making changes to the educational timetable quickly on the example of the "electronic timetable" system

MODEL OF INFORMATION EXPOSURE IN SOCIAL NETWORKS

abstract 1101506116 issue 110 pp. 1789 – 1802 30.06.2015 ru 932
On the basis of hydrodynamic analogy between turbulent transport of momentum, heat and mass transfer, and information in the conditions of modern electronic social networks, we consider a model of informational influence. The flow of information is represented as a stream of random events with simplest flow properties. In addition to the flow of information impact there were introduced the concepts of density, velocity and viscosity of the information flow. These parameters had been derived from the construction of dimensionless criteria characterizing the balance between inertia and viscosity of the information flow of information influence. This criterion serves as a numeric parameter determining the boundary of the transition from low-intensity to high intensity of information influence the turbulent nature of the attack. We have also analyzed the ranges of changes and the meaning of the entered parameters from the point of the organized network information inserts. The existence of the information in time and procedural nature of the concept of information allow us to focus on the properties of information flow as inertia, dynamics and relaxation

ON ONE OF THE APPROACHES TO ENHANCING THE MOTIVATION OF STUDENTS TO EDUCATIONAL AND EXTRACURRICULAR ACTIVITIES THROUGH THE RATING SYSTEM

abstract 1221608052 issue 122 pp. 747 – 756 31.10.2016 ru 576
The problems of increasing the motivation of students of organizations of secondary vocational education and higher education to educational and training activities is due to the use of score-rating approach to recording achievements. The article examines factors that have a negative impact on training and outside training activities, such as TV entertainment, online games, social networks. We consider the activities that have a positive impact on the educational and training activities outside, such as volunteer work, scientific work, socially useful activity. We analyze the advantages and disadvantages of traditional approaches to increase the motivation of students on the basis of a three-level scholarships. The article reveals problems of placing information on the ranking of students in online news sites on educational organizations and media stands. The problems associated with the "transparent" scheme of formation of students rated by forming a student's portfolio have been considered as well. We have given a scheme of a fixed valuation of activities of pupils in points and a formula for calculating the scholarships for student achievements in education and trainings, as well as in volunteer activities. An example of the appearance of a prototype automated system for recording pupils' achievements has been presented. The article also shows data on the implementation of the prototype in educational institutions
