Wave field simulation on the gas-condensate field structure

The results of seismic wave field modeling on the cross-section model of the crust (for Drobyshivske gas-condensate field example) were presented. Complicated cut of the crust, resulting geophysical study, represented as a reservoir model. When modeling, seismic wave field features of two-dimensional cross section were taken into account: longitudinal, transverse and exchange waves received on seismograms of longitudinal and transverse vibrations as a result of default distribution of velocities of longitudinal, transverse waves and the density in half-space medium.

Analysis and implementation of computing workflows for service-oriented CAE/CAD software

This paper is devoted to the architectural aspects of integration of workflow management into service-oriented CAE/CAD software capable to run computations on grid resources. The analysis of possible solutions is based on the workflow execution time estimation. The multilevel workflow concept is also described.

Simulated thermal rheological pattern cutting, the influence of dynamic deformation temperature indicators on the quality of surface finish, and the influence of thermodynamic parameters on the mode of deformation of the workpiece and the tool, and thus the formation of residual stresses and strains.

Extending the features of software for reliability analysis of fault-tolerant systems

The developed software ASNA-2, which is an improved version of the software ASNA-1, is based on the technology of automated estimation of reliability indexes of fault-tolerant systems. This software is designed for automated evaluation of the reliability indexes of fault-tolerant hardware – software systems. This paper describes a software ASNA-2 with the peculiarities of procedures of  reliability analysis of fault-tolerant systems.

Analytical reliability model of a redundant repairable system with limited number of restorations

Modern complex mission-critical systems are built as fault-tolerant systems, i.e. having the ability to function while some of their separate elements have a fault. The complexity of such fault-tolerant systems makes their reliability models quite big and complex. Therefore, such requirements for building models, as the high level of credibility and the appropriate level of formalization, are imposed on these models, which allows to implement the automation to their creating and analysis of reliability and, therefore, using modern computer tools.
