in this paper a first step in classifying the fuzzy normalsubgroups of a finite group is made. explicit formulas for thenumber of distinct fuzzy normal subgroups are obtained in theparticular cases of symmetric groups and dihedral groups.

This paper addresses the problem of motion Chaplygin sleigh, a rigid body moving with three points in contact horizontal plane. One them is equipped knife edge along which there no slipping. Special attention given to case where dry friction present at one support without edge. The equations are written, normal reactions calculated, and behavior phase curves neighborhood an equilibrium point, d...

the topological indices, defined as the sum of contributions of all pairs of vertices (among which are the wiener, harary, hyper–wiener indices, degree distance, and many others), are expressed in terms of contributions of edges and pairs of edges.

-Two sets of higher order equivalent edge currents are introduced which, in combination, account for the first-, the second-, and part of the third-order edge diffraction caused by the fringe wave surface current induced on a perfectly conducting polygonal plate in a radar scattering configuration. The first set represents the fringe wave surface current excited by the incident plane wave at th...

the edge detour index polynomials were recently introduced for computing theedge detour indices. in this paper we nd relations among edge detour polynomials for the2-dimensional graph of tuc4c8(s) in a euclidean plane and tuc4c8(s) nanotorus.

This paper proposed an edge detection scheme which is deduced from Fresnel diffraction. Analysis in this paper shows that Fresnel convolution kernel function performs well on edge enhancement when images are transformed into complex functions. Due to its mathematical complexity, the method is simplified into a linear convolution filter. The new edge detector is designed based on the simplified ...

Whether or not an edge is signi cant for a particular application or situation depends on how the edge is de ned and the environment that the edge is in. If an edge is used as the boundary between a defective region and normal region for visual surface inspection purposes, usually, it has a clear de nition because of the explicitly stated requirements or speci cations from the inspection tasks....

Numerous networks as, for example, road networks, electrical networks and communication networks can be modeled by a graph. Many attempts have been made to determine how well such a network is "connected" or stated differently how much effort is required to break down communication in the system between at least some nodes. Two well-known measures that indicate how "reliable" a graph is are the...

 Edge Detection is an important task for sharpening the boundary of images to detect the region of interest. This paper applies a linear cellular automata rules and a Mamdani Fuzzy inference model for edge detection in both monochromatic and the RGB images. In the uniform cellular automata a transition matrix has been developed for edge detection. The Results have been compared to the ...

Well-differentiated hepatocellular carcinomas (HCC's) induced in the sheepshead minnow Cyprinodon variegatus w ~ t h N-nitrosodiethylamine perm~tted light microscop~cal and ultrastructural comparisons of normal hepatocytes and adjacent HCC cells. Normal hepatocytes contained typical organelles with their intracellular distribution similar to that described for other teleosts. These cells reveal...
