information system


The work is devoted to the problem of creation and implementation of educational services in the process of teaching foreigners listeners of Ukrainian language. Two Web-based learning systems have been developed – an audiovisual training course in the Moodle shell and a KIAP system for constructing Ukrainian language tasks and automated testing of them. It is shown that the Moodle distance learning system was used mostly in the first semester of study. In the second semester, when you have studied professional Ukrainian language, the KIAP system is effective in application.

Applying Smartphones for Positioning in the Middle of the Room

The article deals with the problem of navigating indoors in conditions of satellite signal unavailability. In this case, alternative sources of positioning are used to determine the location of the objects. Use for navigation tasks inside the premises of the smartphone allows you to get comprehensive data on its operation. To solve the problem of navigation, the most important elements of the data sets is the unique identifier of the monitored device and the relative power level of the signal received from it.

Formal Presentation of User Information With Detection Meaningful Objects

The user activity for finding informative meaningful objects needed to solve the problem is considered. To formalize this activity, set theory is used. The mathematical models of formulation of request, analysis of the issued documents and selection of information objects for the solution to the user problem are presented. In addition, mathematical models of intellectual activitiesof user and cognitive processes are developed. The experimental results of the search engines such as Google, Yandex, META, Rambler, Yahoo are given.

Models and methods of synthesis description of rational architecture information system

This paper describes the models and methods, the use of which can solve the problem of synthesis of architecture description of information system. The method of synthesis of options of architecture description of information system was developed. A game-theoretical model describing the synthesis of rational architecture describe of information system. Features of using synthesized description to determine project constraints are described.

Information integration of the repository of software ui components with the data structure of user interaction

The structural model of information integration data about the software UI elements (different graphic representations, properties and parameters, and multi source code implementation in various programming languages, etc.) with the structural modules of tracking and storing data about interactions of user interface is proposed.

Using genetic algorithms for modelling informational processes

In this article genetic algorithms are considered including their types and practical applications. The scientific works of domestic and foreign researchers have been studied. This article presents methods and examples of solving tasks of data mining for genetic algorithms. The description of main components of models of genetic algorithms is presented. A parallel between biological systems and systems aimed at solving technical problems is drawn.

Concept and types of information systems

The article studies modern legal and scientific approaches to the analysis of the category “information system” as the object of legal protection in the information society. It indicates that in the legislation there is a significant number of legal acts containing definitions of “information system”. These definitions are not identical, which generates some legal conflicts and gives ground to assert the need for appropriate categorical apparatus. The article provides classification of information systems according to various criteria.

About variety of informationand and their use in proceedings in cases of administrative offenses

The question of media types and their use in proceedings in cases of administrative offenses. The problems of application in Ukraine varieties of media in proceedings in cases of administrative offenses. The ways of solving them.

Application of mathematical models for improvement of “cloud” data processes organization

The paper presents the main approaches to distributed organization of data in computer networks processing and organization of distributed applications. The main approaches to organization of distributed computing systems are described. The conception of GRID computing and comparative analysis of technologies and architectures of "cloud computing" and GRID systems creation are outlined. The estimations of the advantages and disadvantages of computing processes in web-systems are presented. The analysis of analytical models of cloud computing nodes is made.
