Use of a radioactive check device for redundancy check of ionization chambers
The use of a radioactive check device containing Strontium 90 was investigated to carry out the redundancy checks of Farmer-type ionization chambers. It was not possible to meet the recommended tolerance limits of the redundancy checks without taking into account the angular response of the ionization chambers. The ionization chambers exhibited a maximum variation of 1% in the angular response ...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولSEU Mitigation for SRAM Based on Dual Redundancy Check Method
The application of Static Random-Access Memory (SRAM), becomes more and more widely in aviation. However, the large amount of SRAM cells is very vulnerable to radiation included single-event upset (SEU). Based on the detection requirement of SRAM’s SEU, the detected circuit of the SEU on SRAM is designed. Then the method of redundancy check is used in the reinforcement of the SEU. The test resu...
متن کاملFinding cyclic redundancy check polynomials for multilevel systems
This letter describes a technique for finding cyclic redundancy check polynomials for systems for transmission over symmetric channels which encode information in multiple voltage levels, so that the resulting redundancy check gives good error protection and is efficient to implement. The codes which we construct have a Hamming distance of 3 or 4. We discuss a way to reduce burst error in paral...

دیواره مثانه شامل شبکه انبوهی از فیبرهای عضلانی صاف می باشد که از افزایش ناگهانی فشار مثانه که منجر به انقباض و نشت ادرار از مثانه قبل از پرشدن کامل آن می شود جلوگیری می کند و حدود ۵۰۰ سی سی ادرار را در خود جای می دهد. مجرای پیشابراه که بعنوان محل خروجی برای مثانه محسوب می شود شامل دو لایه عضله صاف و یک ناحیه تنگ شده عضلانی است که تحت کنترل ارادی می باشد و بعنوان اسفنکتر خارجی عمل می کند. هنگام...
