The general scheme of crack growth modeling and periodicity of aviation structure elements checks was developed. The major factors determined the scale of inaccuracy calculation (εN.) based on calculations of crack growth duration (N*) and inspections intervals (τ0) were marked and estimated with the block diagram. © (2014) Trans Tech Publications.

This article describes the construction of the GEMTEC global empirical model of the total electron content in the ionosphere, which is designed for satellite radio navigation. The model is based on the total electron content maps from GPS system measurements. Input data filtration and compression were performed through the natural orthogonal functions expansion method. The suggested model provides more accurate ionospheric delay for compensation of the propagation of radio signals in comparison to the standard model recommended by the interface control document of GPS systems. © 2011 Elsevier Ltd.

For the KdV-Burgers equation on a finite interval the development of a regular profile starting from a constant one under a periodic perturbation on the boundary is studied. The equation describes a medium which is both dissipative and dispersive. For an appropriate combination of dispersion and dissipation the asymptotic profile looks like a periodical chain of shock fronts with a decreasing amplitude (similarly to the Burgers equation case). But due to dispersion each such front is followed by increasing oscillation leading to the next shock-like the ninth wave in rough seas. The development of such a profile is preceded by an initial shock of a constant height. © 2016.

We study the asymptotic profile of the solutions of the Burgers equation on a finite interval with a periodic perturbation on the boundary. The equation describes a dissipative medium, and the initial constant profile therefore passes into a wave with a decreasing amplitude. In the low-viscosity case, the asymptotic profile looks like a sawtooth wave (with periodic breaks of the derivative), similar to the known Fay solution on the half-line, but it has some new properties. © 2016, Pleiades Publishing, Ltd.

A bending resonance magnetoelectric (ME) sensor with maximum generated response voltage is theoretically described. Based on the proposed model, the frequency dependence of the ME coefficient is determined. The optimum thickness of a piezoceramic layer is proposed, which provides a twofold increase in the response voltage. The phenomenon of antiresonance suppression of oscillations in the region of the third bending resonance at 95 Hz is discovered. © 2014 Pleiades Publishing, Ltd.

The article is concerned with the study of asymptotic behavior of solutions of the Burgers equation and its generalizations with initial value - boundary problem on a finite interval, with constant boundary conditions. Since these equations take a dissipation into account, it is naturally to presuppose that any initial profile will evolve to an invariant time-independent solution with the same boundary values. Yet the answer happens to be slightly more complex. There are three possibilities: the initial profile may regularly decay to an invariant solution; or a Heaviside-type gap develops through a dispersive shock and multi-oscillations; or, exotically, an asymptotic limit is a 'frozen multi-oscillation' piecewise-differentiable solution, composed of different smooth invariant solutions.

On the basis of semi-natural simulation using software and hardware of NI GPS Simulation Toolkit and CH-4312 aviation receiver a method of constructing the working area (fields forecast accuracy) satellite navigation system GPS for a given airspace is proposed. This shows the limitations in the use of hardware-software means for assessing the accuracy of determining the coordinates of the object. © 2014 CriMiCo'2014 Organizing Committee, CrSTC.

Head-up displays (HUD) become common equipment in aircraft cockpits. One of the possible and adequate to the HUD specifics visual pilot's interfaces is the "tunnel-in-the-sky" (3D structure on a flat screen). But according to the recent studies the tunnel-in-the-sky does not provide crucial advantages in comparison with traditional methods of presenting navigation information to pilots. This paper considers a stereoscopic version of the "tunnel-in-the- sky" realized as an augmented reality (AR) pocket-size system with see-through light-weight glasses. It consists of low-cost elements and is free of drawbacks that are inherent in the existing synthetic/enhanced vision systems. The design of experiments with desktop simulators of different AR pilot's interfaces (2D, 3D and stereo 3D conditions) and their results are described. The experiment results prove the effectiveness of the proposed stereo solution. © 2014 Elsevier Masson SAS. All rights reserved.

The asymptotic behavior of solutions of the Burgers equation and its generalizations with initial value-boundary problem on a finite interval with constant boundary conditions is studied. Since it describes a dissipative medium, any initial profile will evolve to a time-invariant solution with the same boundary values. Yet there are three distinctive asymptotic processes: the initial profile may regularly decay to a smooth invariant solution; or a Heaviside-type gap develops through a dispersive shock and multi-oscillations; or an asymptotic limit is a stationary 'sawtooth' solution with periodical breaks of derivative. © 2014 Elsevier B.V.
