Background: One of the current problems in studying the mechanical properties and behavior of structurally inhomogeneous media with cracks is the characterization of acoustic wave propagation. This is especially important in Geomechanics and prognosis of earthquakes. Methods: In this work, the authors propose an approach that could simplify characterization of wave propagation in medium with cr...

This paper presents an approach to modeling of field penetration and gives contribution to understanding the real effects of the fields and the sensitivity of human model to electromagnetic radiation generated by mobile antenna. When a human body is exposed to the electromagnetic radiation, because human body contain 70% of liquid, and it contain more liquid near of head, heart, abdomen (near o...

In the characterization of elastic properties of tissue using dynamic optical coherence elastography, shear/surface waves are propagated and tracked in order to estimate speed and Young's modulus. However, for dispersive tissues, the displacement pulse is highly damped and distorted during propagation, diminishing the e®ectiveness of peak tracking approaches, and leading to biased estimates of ...

The paper is concerned with the development and evaluation of a fast, accurate, and versatile method of simulating blast wave propagation within complex built environments. Existing methods of modelling the propagation of a blast wave each fail in at least one of the speed, accuracy or versatility requirements. Conventional simulation, for example, typically takes several days to complete a sin...

The paper presents a novel approach for the analysis and control of distributed systems with an underlying path-graph topology based on the so-called wave-based control perspective. With the help of irrational wave transfer functions, the approach allows us to identify and describe the travelling waves in heterogenous path graphs. The main advantage of this approach is that it shows how a chang...

We extend a result of Freidlin and Gartner (1979) for KPP (Kolmogorov-Petrovskii-Piskunov) wave fronts to the case d ≥ 2 for i.i.d. (independent and identically distributed) random media. We show a wave front propagation speed is attained for the discrete-space (lattice) KPP using a large deviation approach.

In this study, the effect of small-scale of both nanostructure and nano-fluid flowing through it on the natural frequency and longitudinal wave propagation are investigated. Here, the stationary and axially moving single-walled carbon nanotube conveying fluid are studied. The boundary conditions for the stationary nanotube is considering clamped-clamped and pined-pined and for the axially movin...
