Three-Dimensional Visualization of Soil Electrical Conductivity Variation by VRML
High quality three-dimensional (3-D) earth data is very important for environmental assessment studies, precision agriculture and water quality simulation modeling. In the present study, the soil apparent electrical conductivity (ECa) inversed by the EM38 linear model from aboveground EM38 measurements were selected as the data source of 3-D spatial variability. Firstly, the sphere model which ...

control of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولMapping Depth to Argillic Soil Horizons Using Apparent Electrical Conductivity
Maps of apparent electrical conductivity (ECa) of the soil profile are widely used in precision agriculture. A number of ECa sensors are commercially available, each with a unique response function (i.e., the relative contribution of soil at each depth to the integrated ECa reading). Our past research estimated depth to an argillic horizon (i.e., topsoil depth, TD) on claypan soils by fitting e...
