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
In this article, problems of multiparameter fuzzy systems’ state forecasting are reviewed. The algorithm of selection of the equipment on significant parameters of the engine is given
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
In the article, some problems of multiparameter systems’ state forecasting are reviewed. The algorithm of optimal model searching is given
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
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
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
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
The article is devoted to creation of intelligent management system of complex data-processing network. This is caused by the fact that modern telecommunication hardware generates growing amount of statistic information. Expert system is offered to be used in management of networks for the purpose of information security
The article discusses various ways to store chronological data. The mathematical models were constructed for each method. As one of the solutions is the method of data of organization partitioning of a particular DBMS
