1. Computer-aided control system design in secured implementation [№2 за 2013 год]
Authors: Karpov V.V. (karpov@cps.tver.ru) - R&D Institute Centerprogramsystem (1st Deputy Director General), Ph.D;
Abstract: One of the main activities of R&D Institute «Centrprogrammsystem» is computer-aided control system design in secured implementation. The article describes relevance issues of this activity. The relevance is proved by Government careful attention which is generally expressed as a wide range of legal documents regulating activities in the information se-curity area. The choice of secured automated system design approach involves creating a multilevel security system. This se-curity system is based on operating system-level hardware-software complex which includes only domestic project decisions. Other security tools components are arranged on general, custom and functional software levels. They must provide se-curity circuit closure and conformance to the regulatory documents requirements of Federal Service for Technical and Export Control on computer-aided systems security. The development of hardware-software complex of information access security «Rebus» completed the part of the task – to create a security system base. The next task – to create a development technology for secured automated system.

Abstract: The need of ships and submarine training facility which considers exploitation distinctive features and combat employment of particular weapons and military equipment test pieces is increasing. It determines integration processes ori-ented to combining separate task trainers and warfare simulators in training sets which work under one command in one tac-tical environment. The staff of R&D Institute «Centrprogrammsystem» has developed an aggregate approach to distributed simulation architecture designing for such systems as software simulators of weapons and military equipment, task trainers and warfare simulators. There is the main problem when integrating training aids with different functional purpose into train-ing set. It is a construction of common information simulation environment and common administration based on distributed simulation architecture. A computing simulation complex is the main element of a training set which determines distributed simulation system architecture for common information simulation environment construction.

4. Using ontologies in ships operation tasks [№2 за 2013 год]
Author: (kozireviv@gmail.com) - ;
Abstract: The article expounds the possibility of using computer ontologies in ships operation tasks, provides examples of ontologies implementation on a particular subject, considers possible alternatives of knowledge base realization. It also provides a formal ontology model and ontology decomposition variant by levels, conventionally divided into a level of ab-stract description, implementation and knowledge base. In addition, there are descriptions of the ontologies handling prod-ucts, such as Protégé and some of its plugins. With implementing the ontology it is proposed to use ontology description lan-guage OWL promoted by the W3C. Actually it is a dictionary extending the set of terms defined by RDFS. A specialized query language SPARQL can be used to replenish the ontologies contents. The query results are represented by the result sets or RDF-graphs. At the end of the article there are main advantages and problems in ontologies using and some promising ways of solving.

Abstract: The article considers a presentation form of structured data in relational database taking into account condition of search-and-rescue resources information specificity – data are presented as a tree-structured relation. In this case tree-structured relation has a limited quantity of nesting levels and various entities of tree nodes. The article shows certain de-scription methods of the similar structure type in relational database analyzing each method and recommending the presenta-tion form of that kind of structure in a relational database. While choosing presentation form it is necessary to implement such data in software equally as a folded tree and as un-folded structure.
