In this study, a GPU-enabled implementation of an algorithm for the solution of a real-life optimization problem arising in the geoacoustic inversion is proposed. In the inversion algorithm, a single-hydrophone record...

Two control problems for a state-linear controlsystem are considered: the minimization of a terminal functional representable as the difference of two convex functions (d.c. functions) and the minimization of a conve...

We consider a controlsystem described by an evolution equation with control constraint which is a multivalued mapping of a phase variable with closed nonconvex values. One of the evolution operators of the system is ...
We consider a controlsystem described by two nonlinear related equations. The first equation expresses connection between the input and output of the hysteresis operator, whereas the second one is the diffusion equat...
We consider a linear nonstationary system of first order partial differential equations that is not resolved with respect to the derivatives and identically degenerates in the domain. Without using the change of varia...

Nowadays, scientific applications based on a workflow are actively used. Such applications are one of the forms of distributed applied software packages. The modern tools for designing packages do not fully support continuous integration for both the system and applied software for a heterogeneous distributed computing environment. The software quality, its design time, and experiment conduct time can be improved through expanding the scope of continuous integration for packages. To this end, we provide a new approach to ensuring the continuous integration for both the applied and system software within package designing. In practice, the approach applying enables us to significantly decrease in the number of errors and failures when packages are designed and used. Thus, we substantially reduce the time of conducting computing experiments in a heterogeneous distributed computing environment and increase the efficiency for the use of its resources.

The paper describes the approach of graphical objects creation based on domain ontology description, as well as the hierarchy of the ontology, which includes domain ontology, graphical objects ontology and application's visualization ontology. Concept of software is described, that uses this approach for simulation visualization. The basic requirements for software are formulated, the implementation of which eliminates the most disadvantages of existing imaging systems. The main components of proposed software architecture considered to be: the simulation model as an input source;graphics editor that lets to create graphical objects based on geometric primitives;editor of visual models for visual scene's code generation;visualization module to create visual scenes based on generated code;webserver that is used to transfer data between the simulation model and other modules;domain ontology, graphical objects ontology and application's visualization ontology. The main functions of components are suggested, as well as possible methods and techniques for their implementation.
