یکی از روش های اسپکترومتری نوترون استفاده از سیستم اسپکترومتر چند کروی bonner می باشد. اسپکترومترهای bonner sphere به طور گسترده در شیوه های حفاظت پرتو برای تعیین توزیع طیف نوترون در شتابدهنده های ذرات و چشمه های مجهول و دیگر کاربردهای هسته ای استفاده می شوند. این سیستم به دلیل سادگی، قابلیت حمل ونقل، داشتن پاسخ همسانگرد، پوشش دادن پهنه ی وسیعی از انرژی و قابلیت تفسیر و بازیابی داده ها برای اسپ...

 In this article we first introduce the weighted density approximation (WDA) to study the classical inhomogeneous system such as inhomogeneous fluids. Then we introduce the modified weighted density approximation (MWDA) to calculate the structure and thermodynamical properties of the FCC hard sphere crystal. The MWDA is a self consistent method where the free energy is expressed as an unperturb...

The implementation of an automated data entry and report generation system using an optical scanner and commercially available image processing program is described. This method could be easily adapted for use in other fields of medical research where the compilation of a large amount of repetitive data is involved, such as the filling in of questionnaires. Using an optical scanner for data ent...

This study proposed a method for reconstructing three-dimensional (3D) non-axisymmetric temperature fields in water formed by mixed convection surrounding small heating sphere. The is based on the dependence of absorption coefficient at wavelength 1150 nm near-infrared (NIR) region. absorbance images 10-mm-thick cell containing 1-mm diameter steel sphere heated via electromagnetic induction wer...

The Shore hardness test has been widely used and has become the standard for characterizing materials in the rubber and plastics industries. The obtained hardness scale values, ASTM or IRHD, are often related to the static elastic properties of rubber like-materials. Recently, progress on the problem of obtaining dynamic viscoelastic properties has been made through the use of an oscillating sp...

Spherical diffusion flames supported on a porous sphere were studied numerically and experimentally. Experiments were performed in 2.2 s and 5.2 s microgravity facilities. Numerical results were obtained from a Chemkin-based program. The program simulates flow from a porous sphere into a quiescent environment, yields both steady-state and transient results, and accounts for optically thick gas-...
