Introduction: Nuclear moisture density gauges are widely used in construction industry in different countries across the world, including Ghana, on a large scale. Like all irradiating devices, the nuclear gauges should be subjected to radiation safety assessment based on radiation protection and safety principles. Regarding this, the objective of this research was to i...
Introduction: The power transmission lines are the emission source of extremely low frequency (ELF) electromagnetic fields that are considered to have an adverse impact on human health. Therefore the aim of this study was to evaluate the amount of magnetic flux with extremely low frequencies (ELF) around high voltage power transmission lines in the western areas of Tehran in 2012. Material a...
Outlier detection is of great significance in the domain data mining. Its task to find those target points that are not identical most object generation mechanisms. The existing algorithms mainly divided into density-based and distance-based algorithms. However, both approaches have some drawbacks. former struggles handle low-density modes, while latter cannot detect local outliers. Moreover, o...
پسماند چوبی درشت ) coarse woody debris ( یکی از اجزای مهم اکوسیستم جنگل است که نقش مهمی در فرآیندهای این اکوسیستم ایفا میکند. طی دهه اخیر توجه فراوانی به این جزء مهم بومسازگان توسط بوم- شناسان و جنگلشناسان شده است و روشهایی برای نمونهبرداری این جزء مهم اکوسیستم معرفی شده که همگی قطعات cwd را با احتمال نابرابر به عنوان نمونه انتخاب می نمایند. pds ( perpendicular distance sampling ،) dls ( dis...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
