In this paper, we propose a new method to generate a digital map from the aerial photograph. For map generation, it is necessary to develop a technique to recognize various naturaland artificialobjects in the image by computer processing. In general, a photo image has spatial and spectral informations. It is desirable that these two informations are effectively utilized. A new method proposed h...

In this research, a new multidimensional characteristic based upwind scheme for the solution of incompressible Navier-Stokes equations is presented. The incompressible flow equations have been coupled each other by the aid of artificial compressibility method. Unlike to the traditional characteristic based (CB) schemes, the present scheme is genuinely multidimensional in that the local characte...

The experimental determination of protein compressibility reflects both the protein intrinsic compressibility and the difference between the compressibility of water in the protein hydration shell and bulk water. We use molecular dynamics simulations to explore the dependence of the isothermal compressibility of the hydration shell surrounding globular proteins on differential contributions fro...

The compressibility factor (Z-factor) of natural gases is necessary in many gas reservoir engineering calculations. Accurate determination of this parameter is of crucial need and challenges a large number of used simulators in petroleum engineering. Although numerous studies for prediction of gas compressibility factor have been reported in the literature, the accurate prediction of this param...

in this study for the first time a new description of compressibility factor is rendered based on the virial expansion. the compressibility factor as a function of m-factor is qualitatively and quantitatively expressed. at first, we present how may the third, fourth and higher order virial coefficients be logically ignored in order to simplify the virial equation. the results show, when the com...

The aim of this paper is to study the effect organic matter (OM) content on effectiveness soil stabilization process using biopolymer xanthan gum. Five different artificial soils with an in range 1.5 7.7% are subjected unconfined compressive strength (UCS) and oedometer tests evaluate their strength, stiffness compressibility, respectively. These results complemented by analysis SEM images. fro...
