This paper is based on the development of fuzzy Logic based edge detection techniques in digital images. The proposed technique used Sobel operator, Zernike moment operator, and Fuzzy inference system in combination for edge detection purpose. Edge is a boundary between two homogeneous regions. Edge detection refers to the process of identifying and locating sharp discontinuities in an image. I...
one of the locations of renal artery atherosclerosis is at the orifice of the renal artery, therefore thestructure of this orifice was assessed in 6 normal, adult male dogs by light microscopy (lm) andtransmission electron microscopy (tem). for the lm study, processed tissues were embedded in paraffinand sectioned serially into 6-μm thickness. sections were stained with orcein. for the tem stud...
The influence of arbitrary edge loads on the stresses and deformations of thin, elastic shells with general boundaries is studied by means of asymptotic expansions of a general tensor equation. Expansions are made in terms of an exponential or an Airy function and a series in powers of a small-thickness parameter. Most of the steps in the procedure are effected by using the dyadic form of the t...
Friedrichs and Dressler and Gol’denveiser and Kolos have independently shown that the classical plate theory of Kirchhoff is the leading term of the outer expansion solution (in a small thickness parameter) for the linear elasto-statics of thin, flat, isotropic bodies. As expected, neither this leading term nor the full outer solution alone is able to satisfy arbitrarily prescribed edge conditi...
The reassembling of a simple connected graph G = (V,E) is an abstraction of a problem arising in earlier studies of network analysis. Its simplest formulation is in two steps: (1) We cut every edge of G into two halves, thus obtaining a collection of n = ∣V ∣ one-vertex components, such that for every v ∈ V the one-vertex component {v} has ∣degree(v) ∣ half edges attached to it. (2) We splice t...
The extendibility of CR functions on smooth real manifolds in C has been extensively studied by many specialists (see, e.g., [Bo] for references). In this paper we generalize the results of [T1] and [T2] on the extendibility of CR functions to manifolds with boundaries and edges. Recall that a generic manifold M ⊂ C is said to be minimal at p ∈ M if there is no proper CR submanifold S ⊂ M passi...
A stochastic magnetic boundary, produced by an applied edge resonant magnetic perturbation, is used to suppress most large edge-localized modes (ELMs) in high confinement (H-mode) plasmas. The resulting H mode displays rapid, small oscillations with a bursty character modulated by a coherent 130 Hz envelope. The H mode transport barrier and core confinement are unaffected by the stochastic boun...
Edges form the outline of an object. An edge is the boundary between an object and the background, and indicates the boundary between overlapping objects also. So, by identifying edges in an image accurately, all the objects can be located and basic properties such as area, perimeter and shape can be measured. Therefore, edge detection is used to find the discontinuities in surface orientation,...
