A Graphic Generalization of Arithmetic
In this paper, we extend the classical arithmetic defined over the set of natural numbers N, to a set containing all finite directed connected multigraphs having a pair of distinct distinguished vertices. Specifically, we introduce a model F on the set of such graphs, and provide an interpretation of the language of arithmetic L = {0, 1,6,+,×} inside F . The resulting model exhibits the propert...
متن کاملARITHMETIC-BASED FUZZY CONTROL
Fuzzy control is one of the most important parts of fuzzy theory for which several approaches exist. Mamdani uses $alpha$-cuts and builds the union of the membership functions which is called the aggregated consequence function. The resulting function is the starting point of the defuzzification process. In this article, we define a more natural way to calculate the aggregated consequence funct...
متن کاملModern Computer Arithmetic
A 2009 IEEE Transactions on Computers (TC) guest editorial called computer arithmetic “the mother of all computer research and application topics.” Today, one might question what computer arithmetic still o ers in terms of advancing scienti c research; after all, multiplication and addition haven’t changed. The answer is surprisingly easy: new architectures, processors, problems, application do...

متن کاملThe second geometric-arithmetic index for trees and unicyclic graphs
Let $G$ be a finite and simple graph with edge set $E(G)$. The second geometric-arithmetic index is defined as $GA_2(G)=sum_{uvin E(G)}frac{2sqrt{n_un_v}}{n_u+n_v}$, where $n_u$ denotes the number of vertices in $G$ lying closer to $u$ than to $v$. In this paper we find a sharp upper bound for $GA_2(T)$, where $T$ is tree, in terms of the order and maximum degree o...
