Ensemble Average of Three-dimensional Minkowski Tensors of a Gaussian Random Field in Redshift Space

a comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy

این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...

Space as a Semiotic Object: A Three-Dimensional Model of Vertical Structure of Space in Calvino’s Invisible Cities

Following the “spatial turn” of the last 3 decades in humanities and social sciences and the structure of semiotic object, this research studies space as the main semiotic object of Calvino’s (1972) Invisible Cities. Significance of this application resides in examining the possibility of providing a more concrete methodology based on the integration of Zoran’s (1984) 3 vertical levels of const...

On Bézier surfaces in three-dimensional Minkowski space

0. Introduction A Bézier surface is defined using mathematical spline functions whereby the resulting surface has a compact analytic description. This enables such surfaces to be easily manipulated, and they also have greater continuity properties. Bézier curves and surfaces are commonly used in computer-aided design [1,2], image processing [3,4], and finite elementmodeling (e.g. [5–7]). Many o...

A brane in five - dimensional Minkowski space ∗

We discuss the propagation of gravity in five-dimensional Minkowski space in the presence of a four-dimensional brane. We show that there exists a solution to the wave equation that leads to a propagator exhibiting four-dimensional behavior at low energies (long distances) with five-dimensional effects showing up as corrections at high energies (short distances). We compare our results with pro...
