“…Thus, we obtained the overall architecture of the software package "Medved.Telemed", presented in Fig. 1.This approach to the design of an architecture of the telemedical system «Medved.Telemed» was used in the development of an automated system for the production of metallurgical products [8][9][10]. The overall architecture of the Medved.Telemed telemedicine system consists of the  moduls;  data bases;  servises;  instance connector.…”

The work is devoted to design of the software package "Medved.Telemed". In this paper, the main types of architectures and their application situations were studied. Also, we study the main competitors, the legal basis. And current trends in the development of healthcare in the field of digital medicine. Based on the knowledge achieved and identified requirements, a hybrid architecture of a new information system has been developed. The system which is a combination of several architectural patterns, each of which at its own level provides the flexibility and scalability of each component and solution in the whole.

“…Some research effort was also dedicated to the creation of a general architecture for indexing, see, for example, [29,33]. However, these results have been adopted only by specific DBMSes (see, for example, [4]). The query optimizer of DBMSes can take into account the presence of indexes in the planning phase if this is deemed favorable.…”

“…To eliminate this dependency, we can "de-randomize" on the basis of the content as follows. In running Algorithm 1, to choose the level associated with a key k, we suppose to adopt a random generator that is initialized by a seed that we set to k itself 4 . In this way, given a key k, a level is deterministically associated with k, while keeping unchanged the statistics of the levels and the properties described in Section 4.2.…”

Overlay Indexes: Efficiently Supporting Aggregate Range Queries and Authenticated Data Structures in Off-the-Shelf Databases

Commercial off-the-shelf DataBase Management Systems (DBMSes) are highly optimized to process a wide range of queries by means of carefully designed indexing and query planning. However, many aggregate range queries are usually performed by DBMSes using sequential scans, and certain needs, like storing Authenticated Data Structures (ADS), are not supported at all. Theoretically, these needs could be efficiently fulfilled adopting specific kinds of indexing, which however are normally ruled-out in DBMSes design.We introduce the concept of overlay index : an index that is meant to be stored in a standard database, alongside regular data and managed by regular software, to complement DBMS capabilities. We show a data structure, that we call DB-tree, that realizes an overlay index to support a wide range of custom aggregate range queries as well as ADSes, efficiently. All DB-trees operations can be performed by executing a small number of queries to the DBMS, that can be issued in parallel in one or two query rounds, and involves a logarithmic amount of data. We experimentally evaluate the efficiency of DB-trees showing that our approach is effective, especially if data updates are limited.

“…Simulation for analysis and optimization of the processes in organizational and technical systems is widely used in practice [1][2][3]. A metallurgical enterprise information system (MEI-system) developed by "I-Teсo" JSC jointly with the Ural Federal University includes a data collection and analysis subsystem and modeling subsystem containing modules for creating processes models, processes optimization, data preparation, and models integration [4][5][6]. The models integration module solves the problem of applying models in real-time control and decision making processes [6].…”

Results of development of a multiagent simulation model of continuous casting machine with dry change of steel ladles are presented. An algorithm for cutting slabs as well as implementation of this algorithm to the multiagent model of the resource conversion process has been described. The simulation model of the continuous casting machine work is implemented in a metallurgical enterprise information system. During experiments with the model, information is used on the duration of real production processes. This information is formed by the data preparation module of the information system. As a result of simulation-evolutionary modeling with the developed model, recommendations have been obtained for increasing number of units of products going to customers without rejection and reassignment.
