The problem of Stoneley waves in a non-homogeneous orthotropic elastic medium under the influence of gravity was studied recently by Abd-Alla and Ahmed [A.M. Abd-Alla, S.M. Ahmed, Stoneley waves and Rayleigh waves in a non-homogeneous orthotropic elastic medium under the influence of gravity, Appl. Math. Comput. 135 (2003) 187-200], who derived the secular equation of the wave in the implicit f...

The simplest model for the evolution of mean-value a surface gravity wave propagating in random bottom has been connected with telegrapher’s equation. This analysis is based on comparison solution dispersive plane-wave modes binary exponential-correlated disordered floor homogeneous Analytical results exact dispersion-relation are presented. In addition, time-dependent monochromatic waves also ...

For small particles locally injected in a turbulent flow and used as fluid tracers, the reconstruction of mean is biased by particle dispersion caused turbulence. example, jet with nozzle injection, entrained inaccurately measured because all tracked come from source. In this work, we present compensation method that provides accurate velocity for flows non-homogeneous seeding conditions.

Chondrocytes are the living cells in articular cartilage (AC). They synthesize and maintain the extracellular matrix. Their activity is regulated by the interplay of genetic and environmental factors, such as soluble mediators, extracellular matrix composition, and mechanical factors. The mechanical environment of the chondrocytes has a significant influence on the health of the joint. In past ...

In the present paper, an asymptotic model is constructed for the short-time deformation of an articular cartilage layer modeled as transversely isotropic, transversely homogeneous (TITH) biphasic material. It is assumed that the layer thickness is relatively small compared with the characteristic size of the normal surface load applied to the upper surface of the cartilage layer, while the bott...

We study a directed dynamical reaction–diffusion model with no-flux boundary conditions where two populations interact in spatial heterogeneous closed environment state. Both growths are proportional to the same growth law, but dispersal policies migration coefficients differ. The population is diffusing according their resource functions, and carrying capacity bounded habitat. This paper’s mai...

The properties of Rayleigh-type surface wave in a linear, homogeneous and transversely isotropic nonlocal micropolar piezoelectric solid half-space are explored. Dispersion relations for derived both charge free electrically shorted cases. Using an algorithm iteration method MATLAB software, the speed Rayleigh is computed relevant material constants. effects nonlocality, angular frequency, micr...

We have developed a new geometrical method for identifying and reconstructing a homogeneous and highly complete set of galaxy groups in the next generation of deep, flux-limited redshift surveys. Our method combines information from the three-dimensional Voronoi diagram and its dual, the Delaunay triangulation, to obtain group and cluster catalogs that are remarkably robust over wide ranges in ...

Article history: Received 7 April 2011 Received in revised form 17 September 2011 Accepted 18 September 2011 Is wind direction an adequate marker of air mass history? This review looks at the evolution of methods for assessing the effect of the origin and pathway of air masses on composition change and trends. The composition of air masses and how they evolve and the changing contribution of so...

The effect of electrostatic forces on the dispersion small like-charged inertial particles transported by a homogeneous isotropic turbulent flow is analysed means direct numerical simulations coupled with Lagrangian tracking charged particles. results show that particle decreases for increasing charge. Since related to intensity agitation and integral time scale, we analyse effects these two qu...
