شرایط افروزش و اشتعال سوخت‌های گداخت هسته‌ای در حضور ناخالص­‌ها، یکی از موارد مهمی است که طراحی قرص‌های سوخت باید مورد توجه قرار گیرد. این مقاله اثر ناخالصی هسته سنگین طلا بر کلیه فرایندهای احتراق پلاسمای غیرتعادلی دوتریم- تریتیم مدل چهار دمایی آن شکل تابع توزیع انرژی رفتار فوتون‌ها تأثیر می‌گذارد بررسی گرفته است. مطالعه شامل اثرات منفی سوخت، طول زمان تشکیل لکه داغ نتایج محاسبات عددی به­ دست آم...

In the first part of the paper we present a short review of applications of digital differential analyzers (DDA) to generation of circles showing that they can be treated as one-step numerical schemes. In the second part we present and discuss a novel fast algorithm based on a two-step numerical scheme (explicit midpoint rule). Although our algorithm is as cheap as the simplest one-step DDA alg...

ince the 1970s, a disabled people's movement has become established as a political force worldwide. It has confronted the orthodox view that disability should be defined in terms of individual impairment that requires medical treatment. In contrast, disability theory and practice argue that this movement arises from society's failure to remove the wide-ranging social, economic, and environmenta...

Oncoming headlights sometimes cause disability glare that may obscure driver’s vision, both foveal and peripheral. The effects of disability glare on foveal vision have been investigated by many researchers for about 70 years and are generally specified by equivalent veiling luminance (e.g. Stiles and Crawford, 1937). However, few researchers have studied how disability glare impairs peripheral...
