introduction: there is many ways to assessing the electrical conductivity anisotropy of a tumor. applying the values of tissue electrical conductivity anisotropy is crucial in numerical modeling of the electric and thermal field distribution in electroporation treatments. this study aims to calculate the tissues electrical conductivity anisotropy in patients with sarcoma tumors using diffusion ...

Most cosmologists now believe that we live in an evolving universe that has been expanding and cooling since its origin about 15 billion years ago. Strong evidence for this standard cosmological model comes from studies of the cosmic microwave background radiation (CMBR), the remnant heat from the initial fireball. The CMBR spectrum is blackbody, as predicted from the hot Big Bang model before ...

Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...

Abstract Horizontal well can increase productivity and improve the economic benefit, which significantly promotes development of shale gas, tight oil heavy oil. Moreover, it plays an important role in natural gas hydrate. extension ability is one key indexes horizontal well, but always impacted by formation properties structure. Therefore, a model established to analyze impact structure as comp...

the seismic anisotropy is a subject of interest for seismologists and geologists. the information of seismic anisotropy has significant role in geology interpretations (savage, 1999). in this study, we have investigated the upper crust anisotropy in bam area by means of shear wave splitting sg phase. we have selected more than three hundred aftershocks from iiees local temporary seismic network...
