We introduce a high-order discontinuous Galerkin (dG) scheme for the numerical solution of three-dimensional (3D) wave propagation problems in coupled elastic-acoustic media. A velocity-strain formulation is used, which allows for the solution of the acoustic and elastic wave equations within the same unified framework. Careful attention is directed at the derivation of a numerical flux that pr...

Goalof the articleis to develop a mathematical model of behavior thevariable structure system that are affected by oscillations. The dynamic variable systems is considered on example аmotion theinertial vibrating exciter elastic supports.Significance. A large number models under action moving inertial load mostly coversonly general approach solving these problems, or describes specific type equ...

Mobile ad hoc network (MANET) is a group of self-organized mobile nodes that are associated with comparatively low bandwidth wireless links. This paper proposes an effective queuing architecture, which supports both elastic and inelastic traffic. The packets of inelastic flows are always stored ahead of those of the elastic flows. If a link is critically loaded by the inelastic traffic, it resu...

A combined theoretical and experimental study of the depolarization of selected NO(X(2)Π, v = 0, j, F, ɛ) levels in collisions with a thermal bath of Ar has been carried out. Rate constants for elastic depolarization of rank K = 1 (orientation) and K = 2 (alignment) were extracted from collision-energy-dependent quantum scattering calculations, along with those for inelastic population transfer...

The present paper is devoted to the numerical analysis and experimental tests of compressed bars with built-up cross section which are commonly used as a top chord roof trusses. significant impact on carrying capacity for that kind elements in case out-of-plane buckling appropriate choice battens provide interaction between separate members. Linear results nonlinear static results, material geo...

During the immune response, neutrophils display localized mechanical events by interacting with their environment through the micro-vascular transit, trans-endothelial, and trans-epithelial migration. Nano-mechanical studies of human neutrophils on localized nano-domains could provide the essential information for understanding their immune responsive functions. Using the Atomic Force Microscop...

Cloud computing is a new computational and commercial model. It brings the illusion of a virtually infinite computing infrastructure/platform that provides advanced features. The increased number of VMs and applications in virtualized data centers triggers serious scalability concerns with regards to monitoring. Many features of Cloud need supports from underlying Cloud monitoring system. There...
