طوفان های گرد و غباری که اغلب در مناطق خشک و نیمه خشک جهان روی می دهند حجم زیادی از ذرات معلق را با خود حمل میکنند و از اینرو به عنوان یکی از مهمترین معضلات زیست محیطی در مقیاس های منطقه ای و بین المللی تلقی میگردند. این تحقیق به ارزیابی مقادیر فلزات سنگین در ذرات گرد و غبار ته نشین شده در شهرهای سنندج، خرم آباد و اندیمشک در غرب ایران میپردازد. نمونه برداری ذرات گرد و غبار از 30 خرداد 1391 بمدت...
Compiling indexing operations on n-dimensional arrays into efficiently executable code is a challenging task. This paper focuses on the reduction of offset computations as they typically occur when transforming index vectors into offsets for linearized representations of ndimensional arrays. We present a high-level optimization to that effect which is generally applicable, even in the presence ...
