The aim of this work is the detection of solar photovoltaic panels in low-quality satellite photos. It is important to receive the geospatial data (such as country, zip code, street and home number) of installed solar panels, because they are connected directly to the local power. It will be helpful to estimate a power capacity and an energy production using the satellite photos. For this purpose,...
The general structure and main principles of creating a multi-version post-severe NPP accident monitoring system, which consists of one wired and three drone-based wireless network subsystems, are proposed. Reliability block diagrams for the system are built. On the basis of the reliability block diagrams, reliability models of the system are developed. The dependence on probability of failure-free...
To increase the security of intrusion detection system, generalized structure of highly performance adaptive system for cyber attacks detection was developed. To improve its robustness, methods of artificial intelligence were proposed. Neural immune detectors were used as the main tool for identifying cyber attacks. These detectors for cyber attacks identification and classification and other vulnerable...
The authors propose the agent-oriented approach for solving problems of IT project planning. The tasks hierarchy of a management planning system in IT projects is formed. Both the use case and context diagram of processes in project management planning are built. The simulation model of the multi-agent system on AnyLogic base is studied.
The tremendous growth rates of Internet and volume of content stored on its servers requires the creation of tools for automatic content analysis and processing. Intelligent systems for content processing aim to simplify and automate such tasks as content analysis and classification, finding keywords and building digests, distributing content according to specified criteria. This paper presents the...
Projects are one of the most important organizational patterns in industry and society. Projects drive change and change takes place in a projectized world. Therefore, project management is a competence field which is required in many areas and on various competence levels. Master education in project management is a special type of delivery for project management competence. It combines a scientific...
