ANALYSIS OF GEOSTATISTICS THROUGH ROUGHNESS DATA SAMPLING OF SOIL AT DIFFERENT SCALES

the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...

Scattering from Surfaces with Different Roughness Scales: Analysis and Interpretation

This paper discusses several approaches to scattering from slightly rough» very rough, composite, and rough spherical surfaces. Average incoherent scattering cross sections for slightly rough surfaces are obtained using a perturbation technique for a perfect conductor, and for a surface material which is homogeneous (with variable permeability, \Lr, as well as permittivity, «r)« The results, co...

determination of factors controling the pb-zn mineralization and proposing complementary exploration program at ay-ghaleh-si prospect through integrating exploratory data

محدوده اکتشافی آی قلعه سی به وسعت 19کیلومتر مربع یکی از محدوده های شرکت توسعه معادن روی ایران است که بدلیل وجود معدن متروکه سرب و روی در آن، از اهمیت خاصی برخوردار است. این محدوده در 24 کیلومتری جنوب شرق شهرستان تکاب، در حدفاصل دو استان آذربایجان غربی و استان کردستان و در نقشه زمین شناسی 1:100000 تکاب قرار می گیرد. هدف از انجام این پایان نامه بررسی کنترل کننده های کانی سازی در معدن متروکه آی ...

Analysis of spatial variability of soil properties using geostatistics and remote sensing

Soil mapping is one of the basic studies in the natural resource sector. The purpose of this study was to analyze spatial of soil properties on the map of arid areas and deserts. For this purpose, a region with an area of 600 hectares in Qom that considered Salt Lake watershed. Specified methods used include inverse distance methods, radial functions, and prediction local general estimate. Krig...
