COMPARISONS AMONG THREE COUPLING FORMS OF CYLINDRICAL NODAL EXPANSION METHODS
نویسندگان
چکیده
Nodal expansion method (NEM) is a typical nodal in solving neutron diffusion equation coarse mesh spatial discretization. NEM has been extended to cylindrical geometry previous studies. Cylindrical can be realized by different forms, where the variables coupling equations are classified as net current, flux or partial current at surface, respectively. The three types of forms have implemented PANGU code for high temperature gas-cooled reactor (HTGR) physics analysis. This paper derives NEM, and analyzes their performance HTGR model containing void region.

چکیده: بررسی ادبیات مربوطه در کشور در زمینه یادگیری زبان انگلیسی نشان میدهد که علیرغم اهمیت املا در فرآیند یادگیری به طور عام و یادگیری زبان انگلیسی به طور خاص، این مولفه از جایگاهی متناسب با اهمیت آن برخوردار نیست و عمدتاً نادیده گرفته شده است. تحقیقات گستردهای در خارج از کشور در مورد ماهیت این مولفه صورت گرفته است، در حالی که به جرأت میتوان گفت در داخل کشور گامی در مورد درک ماهیت آن و فرآی...
15 صفحه اولEstimation of Ki in a competitive enzyme-inhibition model: comparisons among three methods of data analysis.
There are a variety of methods available to calculate the inhibition constant (Ki) that characterizes substrate inhibition by a competitive inhibitor. Linearized versions of the Michaelis-Menten equation (e.g., Lineweaver-Burk, Dixon, etc.) are frequently used, but they often produce substantial errors in parameter estimation. This study was conducted to compare three methods of analysis for th...
متن کاملMisidentifications of specific forms of cross-frequency coupling: three warnings
Cross-frequency coupling (CFC) between neural oscillations has received increased attention over the last decade, as it is believed to underlie a number of cognitive operations in different brain systems. Coupling can take different forms as it associates the phase, frequency, and/or amplitude of coupled oscillations. These specific forms of coupling are a signature for the underlying network p...
متن کاملNodal Domains of Maass Forms I
This paper deals with some questions that have received a lot of attention since they were raised by Hejhal and Rackner in their 1992 numerical computations of Maass forms. We establish sharp upper and lower bounds for the L2-restrictions of these forms to certain curves on the modular surface. These results, together with the Lindelof Hypothesis and known subconvex L∞-bounds are applied to pro...

where V 2 is the two-dimensional Laplace operator and k is the wavenumber of the radiation field. The function Vstands for a typical component of the electric or magnetic field. In cylindrical coordinates, the basic solutions of the Helmholtz equation are of the form Hn (kr ) exp (int~), where Hn is the Hankel function of integer order n while r and ot are a radial and an angular coordinate, re...
