In the paper, we propose a new model of the natural gas market simulation. It takes into account the random nature of the natural gas demand that depends, for example, on temperature fluctuations during the heating period. The natural gas supplier strategy is optimized with the reservation of the necessary amount of fuel to compensate for demand fluctuations. To implement simulation modeling, we developed a scalable application with the DISCOMP framework. We apply DISCOMP to develop and use scalable applications in a heterogeneous distributed computing environment. The application significantly increases the number of model runs and improves the simulation accuracy in comparison with the Mathcad computations on a personal computer.

We represent a new approach to the development and use of a subject-oriented heterogeneous distributed computing environment for solving large-scale problems of energy security research. Both the development of scalable applications (distributed applied software packages) and the computing resources integration are conducted using the Orlando Tools framework. It supports the collaborative application development based on the continuous integration of their software. Computation management tools in Orlando Tools are integrated with a multi-agent system. We propose special multi-agent tools for the heterogeneous resource allocation in the environment. These tools apply knowledge about the subject domain specifics of solved-problems and computing environment characteristics. The effectiveness of such management is highlighted by the results of solving practical problems of energy security research.
Observer-based self sensing for digital (on–off) single-coil solenoid valves is investigated. Self sensing refers to the case where merely the driving signals used to energize the actuator (voltage and coil current) ...

The paper describes the main principles of visualization software development, as well as implemented by this software approach, which is based on the use of ontologies to describe both the rendered domain, and the rules of its 3Ddisplaying. This approach allows the user to avoid programming the 3Dscene and describe it in terms of the research area. The paper set out a formal model of a software tool, its architecture, basic modules and ontology structure. The process of visual scene design and creation is described, including the steps of ontology modelling, visual objects creation, formation of scene describing rules, code generation, visualization, organization of data exchange between visualization software and data source. WebGLbased library was chosen as primary means for 3D graphics rendering, which allows to create visual scenes in the user's web browser. Examples of generated scenes and the question of its performance are also discussed in the article.
An optimal control problem for the continuity equation is considered. The aim of a controller is to maximize the total mass within a target set at a given time moment. An iterative numerical algorithm for solving this...
