Material Identification Methods in Spectral Radiography Using CdTe Semiconductor Detectors
Material identification in radiography is traditionally performed by dualenergy systems, using double exposure technique or two-layers detectors. Performance of such systems results from the closeness of the materials to be discriminated, from photonic noise, and energetic discriminating power of the detector. For difficult problems such as explosive detection in luggage, conventional dual-ener...
متن کاملCCD and CMOS sensors
The charge-coupled device (CCD) has been developed primarily as a compact image sensor for consumer and industrial markets, but is now also the preeminent visible and ultraviolet wavelength image sensor in many fields of scientific research including space-science and both Earth and planetary remote sensing. Today’s scientific or science-grade CCD will strive to maximise pixel count, focal plan...

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولRadiographic characteristics of skull fractures resulting from child abuse.
Radiographic characteristics of skull fractures in 39 cases of documented child abuse were compared with skull fractures in 95 cases of accidental injury to determine if differential features could be identified. All children were less than 2 years old. Emergency room and hospital records for these patients were also reviewed. The results of this study show that clinical features did not provid...
