Resolution of the Hierarchy of Many-body Distribution Functions
نویسنده
چکیده
The rigorous evolution equation for the one-body distribution function f(t) describing an imperfect gas is not closed according to the investigations of Bogoliubov, Born, Green, Kirkwood, Yvon and others (B—B—G—K-Y hierarchy). The analysis of this equation is made in terms of connected diagrams. It is shown that in the bulk limit this equation can rigorously be transformed into an equation which is closed with respect to f(t) and which contains a given initial correlation. The latter equation forms a basis of discussing various problems related to irreversibility and transport phenomena.

A resolution comparison of horizontal and vertical magnetic transfer functions
The main goal of the present study is to identify characteristics of the inter-station horizontal magnetic responses and the vertical magnetic data, as two types of magnetotelluric transfer functions, in the modeling procedure. Through consideration of model responses and two-dimensional inversion of synthetic data, sensitivity of the data components in detecting different geophysical structure...
متن کاملDetermination of Fiber Direction in High Angular Resolution Diffusion Images using Spherical Harmonics Functions and Wiener Filter
Diffusion tensor imaging (DTI) MRI is a noninvasive imaging method of the cerebral tissues whose fibers directions are not evaluated correctly in the regions of the crossing fibers. For the same reason the high angular resolution diffusion images (HARDI) are used for estimation of the fiber direction in each voxel. One of the main methods to specify the direction of fibers is usage of the spher...

This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...

One of the main challenges for transportation engineers is the consideration of pedestrian safety as the most vulnerable aspect of the transport system. In many countries around the world, a large number of accidents recorded by the police are composed of accidents involving pedestrians and vehicles, for example when pedestrians may be struck by passing vehicles when crossing the street. Carefu...
متن کاملIsma’ili Thesis on the Ecclesiastical Hierarchy
Though it is widely assumed that Sunni Islam does not have an equivalent to the Christian ecclesiastical hierarchy, Shii groups such as the Medieval Ismailis did have an organised teaching, spiritual, and temporal hierarchy. Evidence gathered from primary sources shows that this Ismaili 'ecclesiastical' hierarchy is strictly intertwined with the Ismaili interpretation of Neoplatonic cosmology a...
