crystals, multi-crystals or amorphous materials. The most important problem of such Si solar cells is to increase conversion efficiency. In crystalline silicon solar cells, surface texturing is used to trap... silicon solar cells[4-5]. Among three crystalline phases (anatase, rutile, and brookite), in which TiO2 can exist, the anatase phase is desired in AR coating applications because of high refraction......
Risk quantification in grade variability of gold deposits using sequential Gaussian simulationTayfun Y. Yunsel(Mining Engineering Department, Cukurova University, Adana, 01330, Turkey)Abstract:Risk quantification in grade is critical for mine design and planning. Grade uncertainty is assessed using multiple grade realizations, from geostatistical conditional simulations, which are effective......
