In this paper, we introduce bi-continuous random media morphology to describe the snow structure. Both analytical method and numerical method are used to study the scattering properties of bi-continuous media with discrete permittivities in the frequency of 18.7GHz. The bi-continuous medium is based on a continuous representation of interfaces between inhomogeneities within the medium [1]. The ...

We present a well-posedness result for strong solutions of one-dimensional stochastic differential equations (SDEs) the form $$\mathrm{d} X= u(\omega,t,X)\, \mathrm{d} t + \frac12 \sigma(\omega,t,X)\sigma'(\omega,t,X)\,\mathrm{d} \sigma(\omega,t,X) \, \mathrm{d}W(t), $$ where drift coefficient $u$ is random and irregular. The regular noise $\sigma$ may vanish. main contribution pathwise uniquen...

Deployment of sensors in any irregular terrain with 100% coverage and connectivity is a challenging issue in the field of Wireless Sensor Networks. Traditional deployments often assume homogeneous environments, which ignore the effect of terrain profile as well as the in-network obstacles situated randomly like buildings, trees, roads and so on. Proper deployment of sensors in such irregular re...

This paper presents an experimental study the influence of wave parameter on the damage of reshaping seawall, model tests have been performed in several water level conditions. The experiments of physical modeling of this research have been done in the flume of the Soil Conservation and Watershed Management Research Institute (SCWMRI). The waves applied to the structure model are irregular and ...

The important characteristic of sea waves is their high energy density, which is the highest among renewable energy sources. Having up to 2700 km. of shoreline, Iran has a great potential in construction of offshore wave buoys (hereafter called OWB). In this article a OWB model with the possibility of assembling different buoy configurations is introduced. The system is exposed to regular and i...

Many natural and man-made media such as the atmosphere, oceans, geophysical media, biological media, and composite and disordered materials have random spatial inhomogeneities and vary randomly in time, and these media are called “random media. ’’ Microwaves, optical waves, and acoustic waves propagating in these media experience random fluctuations in space and time, and these fluctuations aff...
