Description
This article describes the methods of organizing an automated job preparation in mathematics and natural science disciplines with macros among Visual Basic for Application. Showing data generation algorithms for the problems, methods of testing the work performed

Description
The article discusses the methodology of optimal configuration selection and structuring of distributed information systems for collecting and storing historical data from multiple data centers

01.00.00 Physicalmathematical sciences
DescriptionThe article presents the theorem of Chebyshev on the distribution of primes, considering functions that approximated prime numbers. We have also considered a new function, which is quite good for approximation of prime numbers. A review of the known results on distribution of prime numbers is given as well

FUNDAMENTAL THEOREM OF ARITHMETIC AND SOME OF ITS ASPECTS
01.00.00 Physicalmathematical sciences
DescriptionIn this article, we present the fundamental theorem of arithmetic and its role. We consider various rings for its performance

METHODS OF DEVELOPMENT OF TESTS IN THE AUTOMATED MONITORING SYSTEMS CALLED “KONTROL”
DescriptionThe article describes the basic techniques for working with Kontrol automated monitoring system. We suggest the algorithm for creating and editing test databases, software settingsgovernmental applications, technologies used in the tests of text, graphics and multimedia data

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

THE ISSUE OF A FUZZY EXPERT SYSTEM DEVELOPMENT
DescriptionThe article considers questions of the information system of choice of development tools of automated systems based on fuzzy logic model. The technique allows us to develop information systems in an objectoriented programming language. Information system allows selecting the most effective tool without additional researches

ON THE NUMERATIONS OF THE FINITE PARTIALLY ORDERED SETS
01.00.00 Physicalmathematical sciences
DescriptionIn this article, we discuss various issues related to the formulas approximating the distribution function of prime numbers pi(x). This question has occupied many scholars, but the exact function is well approximated function pi(x) over the number of positive integers not. Based on certain hypotheses, we present a new function s(x) is very well approximated pi(x). The above article hypotheses are so important that their numerical validation and refinement for the lengths of the segments more in 1014  one of the main areas related to the problem of approximation of the function pi(x) throughout the series of natural numbers. After analyzing the behaviors and constructs many functions, we are building the basis of the function s(x), which is well approximates the function pi(x) throughout the series of natural numbers. We also present a table of values for x, less or equal 1022 for the difference of s(x)  pi(x)

Description
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

Description
The article considers questions of workflow in the educational organization. It revealed the need to process everyday documents, which exchange does not have the character of strict accountability, but they are also crucial to the implementation of the work in the educational organization. The exchange of such documents is different from the traditional workflow, primarily, it is the speed of document creation and sharing them. We identified other requirements and limitations to the daily workflow of documents. The study proposed to divide document on direct and indirect. The article formulates basic differences between direct and indirect document. It also analyzes the advantages and disadvantages of traditional approaches based on file servers and cloud data storage. We list problems of implementation of the account running errands. We have offered the structure of the order in the approach. The study shows an approach to increase the quality of the educational process based on the implementation of the indirect workflow through the use of centralized WEB system for the exchange of files, documents, accounting running errands, organizing indirect document. The proposed approach takes responsibility for storage of files from the technical support department of educational organizations can work with the system with mobile and desktop devices
