Abstract:

This article describes the development of a recommender system for selecting players based on machine learning. The system introduced the example of hockey with the possibility of expanding its use in various team sports. For each sport different roles and characteristics of the players were considered. The article analyzes information about hockey, football, basketball and volleyball. The characteristics of the players are structured and divided into general groups. For each parameter coefficients are displayed that show the impact on the result of the match. Various machine learning algorithms were used to build the model. The web interface of the application has been created.

Abstract: This article discusses approaches to the creation of an electronic scientific journal tool platform that provides the publication of multimedia materials through a web interface. The problems associated with the need to include multimedia data of different types are described and a working prototype of the multimedia of the scientific journal is presented.

Abstract: Research on design and development of software and technological support for geo-portal of ICM SB RAS are discussed. Its main components and implementation details are presented. A number of problems are discussed in details, such as web-based metadata catalog, the logic of building applications based on web services geoportal. A list of implemented information systems, based on discussed technologies is presented. The authors were directly involved in the develop-ment and implementation of geoportal based projects. In developing the software many different software libraries and components were used. Web mapping user interface was created using a number of open source libraries. To create a server-side web application authors used GIS platforms MapGuide Open Source and Min-nesota Mapserver. GeoWebCache was another essential component of distributed web mapping ap-plications. By analyzing and summarizing the experience gained creating information systems, it should be noted that the use of geoportal-based solutions in this area, can dramatically improve the efficiency of software development and problems solving.

Abstract: Mass identification of a list of radio sources with the sky surveys of different ranges of the electromagnetic spectrum has undoubted interest to astronomers. Identification of the radio sources is not a straightforward procedure because of the different angular resolution, sensitivity limit, coordinate precision  of the radio catalogues, as well as due to the morphological structure of radio sources themselves.

Abstract: The observatory archive system includes a digital data storage and a search information system (SIS) with a dynamic web-based interface and http data access. To date, the system includes 16 digital collections of observational data (local archives), obtained on different instruments, operating or working on the telescopes. The earliest data refer to the end of 1994. There are currently actively replenished 6 local archives. The data storage includes a temporary storage area, located on a file server of the 6-m telescope (BTA), and the area of permanent storage. Permanent storage area includes CD / DVD-discs, a hard disk of the dedicated archive server and also a large capacity flash disk. For data protection during emergency situations or I/O defects of disks, we provide two full copies of the CD / DVD disks and two copies of the archive data on the hard disk of the archive server. One copy (A0) repeats optical discs, the other (A1), with the slightly modified directory structure, actually used by the SIS. D igital media devices and read-write data drives can not be attributed to long-term storage devices. For long-term storage of digital data it is necessary to provide rewriting of information every 5-10 years on a new type of media. Archive copies A0 and A1 are also supported for this procedure of rewriting. Archival data (A1) is repeated on a flash disk with the addition of a dump of tables and programs. There is the system backup for restoring after an emergency on the server. To ensure the modernization of the SIS, we support the two schemes of the database - test and operational. All our developments take place in the test database schema. When modifying the scheme after its checking the SIS switched to an updated version of the database. The original copy of the A0 and the availability of test database scheme allow to modernize the SIS, even at the level of the tables. Currently, the SIS implemented on DBMS PostgreSQL 8.3.7.

Abstract:

The paper is devoted to the development of an expert system for diagnosing pneumonia based on fuzzy logic and implemented using the Mamdani algorithm. The paper discusses the main stages of the system development, including fuzzification of input data, definition of fuzzy rules based on medical expert knowledge, aggregation of fuzzy inferences and their defuzzification to obtain the final diagnostic result. The web interface of the system is implemented using the Django framework, which ensures ease of interaction for users. The use of a medical expert system for diagnosing pneumonia can reduce the time required to establish a diagnosis and improve the quality of diagnosis by integrating the experience of medical experts and modern information technologies.
