Designing models of educational processes execution in secure distributed system
.
Prokofiev D., Starykh V.
The paper is devoted to describing of the methods applied to create models of educational processes. These models was prepared to be implemented in a secure distributed system. The methods for model search, implementation and optimization were inspected in relation to the quality of education and distance learning. In order to improve metadata, the feedback process modeling was introduced.

Multi-level multi-agent systems (MASs) with dynamic structure are widely used in solving important applied problems in telecommunication, transportation, social, and other systems. Therefore, ensuring correct behavior of such systems is an actual and important task. One of the most error-prone stages of system development in the framework of model-oriented approach is the implementation stage, in ...

In distributed systems designed using microservice architecture, business functions are encapsulated in independently deployable modules that asynchronously access one another using messaging. The choice of the method of functions assignment to microservices being designed, and corresponding data placement, can be carried out both heuristically and using a specialized methodology based on domain-oriented design and relational ...

Explosive growth of raster data volumes in numerical simulations, remote sensing and other fields stimulate the development of new efficient data processing techniques. For example, in-situ approach queries data in diverse file formats avoiding time-consuming import phase. However, after data are read from file, their further processing always takes place with code developed almost from ...

Coordination of several distributed system components is an error-prone task, since interaction of several simple components can generate rather sophisticated behavior. Verification of such systems is very difficult or even impossible because of the so-called state space explosion problem, when the size of the system reachability set grows exponentially on the number of interacting agents. ...

An array DBMS streamlines large N-d array management. A large portion of such arrays originates from the geospatial domain. The arrays often natively come as raster files while standalone command line tools are one of the most popular ways for processing these files. Decades of development and feedback resulted in numerous feature-rich, elaborate, free and ...

Checking the correctness of distributed systems is one of the most difficult and urgent problems in software engineering. A combined toolset for the verification of real-time distributed systems (RTDS) is described. RTDSs are specified as statecharts in the Universal Modeling Language (UML). The semantics of statecharts is defined by means of hierarchical timed automata. The ...

One of the promising approaches to the development of distributed systems is to divide it into a number of independently deployable modules (microservices) that use messaging for data interchange. As a rule, each individual microservice implements some business function, completely hiding its implementation details, including method of data persistence – be it tables in the ...

We propose ADOM – an accelerated method for smooth and strongly convex decentralized optimization over time-varying networks. ADOM uses a dual oracle, i.e., we assume access to the gradient of the Fenchel conjugate of the individual loss functions. Up to a constant factor, which depends on the network structure only, its communication complexity is the ...
