Despite of the great advances in Global Positioning System (GPS) technology, millions of people still cannot be located when they are in indoor environment. The signal transmitted from the Navstar satellites experiences severe attenuation while penetrating all the construction materials. The characteristics of the indoor propagation is still not well understood and the question whether the GPS ...

It has already been confirmed that the traffic in high-speed terrestrial network presents self-similarity, but there is little research on self-similarity of traffic in satellite network. Considering time-varying network topology and link status, this paper analyzes the aggregation and propagation of self-similar traffic between nodes in satellite network. Furthermore, a sort of special network...

The impact of including the diffraction loss in the interference modeling on the system throughput is assessed in the context of cognitive Ka-band satellite systems. In particular, we focus on the cognitive satellite downlink, where Geostationary (GEO) Fixed Satellite Service (FSS) terminals receive interference from the incumbent Fixed-Service (FS) microwave links. We present numerical results...

to evaluate the earth seismic response due to earthquake effects, ground response analyses are used to predict ground surface motions for development of design response spectra, to compute dynamic stresses and strains for evaluation of liquefaction hazards, and to determine the earthquake induced forces that can lead to instability of earth and earth-retaining structures. most of the analytical...

In the following paper we will consider Navier-Stokes problem and it's interpretation by hyperbolic waves, focusing on wave propagation. We will begin with solution for linear waves, then present problem for non-linear waves. Later we will derive for numerical solution using PDE's. Also we will design a Matlab program to solve and simulate wave propagation. Keywords1: Navier-Stokes equations, F...

A simple model of inductor-coupled bistable oscillators is shown to exhibit pulse wave propagation. We demonstrate numerically that there exists a pulse wave which propagates with a constant speed in comparatively wide parameter region. In particular, the propagating pulse wave can be observed in non-uniform lattice with noise. The propagating pulse wave can be observed for comparatively strong...

BACKGROUND Cartilage elasticity changes with cartilage degeneration. Hence, cartilage elasticity detection might be an alternative to traditional imaging methods for the early diagnosis of osteoarthritis. Based on the wave propagation measurement, Shear wave elastography (SWE) become an emerging non-invasive elasticity detection method. The wave propagation model, which is affected by tissue sh...

In the presence of multiple scattering, waves and particles behave fundamentally differently. As a model for the stability of the temporal evolution of particle and wave propagation, a scattering system is presented in which particle propagation is strongly unstable while wave propagation is significantly more stable. Both analytical and numerical evidence for the different stability properties...
