WebThe circulant graphs are of particular interest as models of communication networks. In this work, we present new reliability analysis results for circulants based on the concept of restricted edge connectivity, which generalizes the super-λ property of a graph. WebIn this paper, an encryption model for the grayscale and color images based on novel magic square, and differential encoding technique along with chaotic map has been proposed. The coordinate positions of the plain image have been randomized by implementing the 2D Arnold scrambling algorithm in confusion phase. The magic square constructed by a …

WebChelvam [8], and Wang [10] have worked on Cayley graphs. For example, one can refer the survey by Tamizh Chelvam and Sivagami [9] for domination in Cayley graphs. The Cayley graph constructed out of the finite cyclic group ℤ n; n ≥ 2 along with a symmetric generating set Ω is called a circulant graph and the same is denoted by Cirðn;ΩÞ. The WebIn mathematics (in particular, functional analysis), convolution is a mathematical operation on two functions (f and g) that produces a third function that expresses how the shape of one is modified by the other.The term convolution refers to both the result function and to the process of computing it. It is defined as the integral of the product of the two … headlamp flashlight with camera

WebAutomorphism groups of circulant graphs — a survey 5 4. Circulant graphs on a prime number of vertices In 1973, Alspach proved the following result on the automorphism groups of cir-culant graphs on a prime number of vertices. Theorem 4.1. [2] Let p be prime. If S = ∅ or S = Z∗ p, then Aut(X)= S ; otherwise, Aut(X)= {T a,b: a ∈ E(S),b ∈ Z WebIf we implement the MP decoders of LDPC codes in hardware,it comes to complex routing due to“random-like” connected edges in Tanner graphs.It not only costs a large amount of chip area,but also significantly increases the computation delay[20].Thus,many researchers focused on a class of structured LDPC codes,QC-LDPC codes,whose parity-check … WebHence, conventional initial synchronisation cannot be readily employed because of its potentially excessive delay. In this paper, an extrinsic information transfer (EXIT) chart assisted approach is used for the convergence analysis of m-sequences using recursive soft sequence estimation (RSSE) in the context of Nakagami-m fading channels. gold medal tournament
