In this paper a transient free convection flow around a sphere with variable surface temperature and embedded in a porous medium has been considered. The temperature of the sphere is suddenly raised and subsequently maintained at values that varies with position on surface. The method of asymptotic expansions is applied for small Rayleigh numbers and then a finite-difference scheme is used to s...
In this paper, by using the nonlinear coherent states on a sphere, we introduce superposition of the aforementioned coherent states. Then, we consider quantum optical properties of these new superposed states and compare these properties with the corresponding properties of the nonlinear coherent states on the sphere. Specifically, we investigate their characteristics function, photon-number d...
In medical etiquette and ethics, benefit and harm assessment includes risk evaluation, rational risk, distinction between medical and non medical utilitarian considerations, individual and community benefit ratio, and issues of the like. This article explores philosophical foundations of this issue. In philosophy, benefit/harm reduces to pleasure/pain and good/bad. Pleasure (spiritual and non-...
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...
In the current age of advanced technologies, there is an escalating demand for reliable wireless systems, catering to high data rates mobile multimedia applications. This article presents a novel approach concept Self-Concatenated Convolutional Coding (SECCC) with Sphere Packing (SP) modulation via Differential Space-Time Spreading- (DSTS-) based smart antennas. The two transmitters provide tra...
Abstract. In this article, a method for the extrinsic calibration of 2D laser range finder and camera is presented. This technique produces 3D point cloud from test field by connecting to servomotor. study, ping balls standard photogrammetric targets were employed as field. Ping pong are used because they can be easily recognized in data camera. To calculate parameters between finder, these con...
