Applications of Graph Theory in Real Life Sharathkumar.A, Final year, Dept of CSE, Anna University, Villupuram Email: kingsharath92@gmail.com Ph. No: 9789045956 Abstract Graph theory is becoming increasingly significant as it is applied to other areas of mathematics, science and technology. It is being actively used in fields as varied as biochemistry (genomics), electrical engineering (communication networks and coding theory), computer science (algorithms and computation) and operations

connected graph. A vertex V ϵ G is called a cut vertex of graph G, if “G – V” results in a disconnected graph G. 3.28. Cut edge: Let G= (V, E) be a connected graph, an edge E ϵ G is called a cut edge of graph G, if “G-E” result in a disconnected graph G. 3.29. Euler graph: A connected graph G=(V, E) is said to be Euler graph (traversable), if there exists a path which includes, (which contains each edge of the graph G exactly once) and each vertex at least once (if we can draw the graph on a plain

Chemistry 262 Lab TA: Mona Khorani Yuen Wai Ng Group Members: Mihir Palan and Haelyn Epp Group 6 February 20, 2018 Establishment of Food Dye Content and Concentration in Purple Gatorade Abstract The experiment of determining the different food dyes present in the purple Gatorade and then creating a solution with the correct color and concentration of the Gatorade chosen. Trials were done with blue and red dyes to dilute the concentrations of the respective dyes in order to find the amount of dyes

EDSs are mainly designed meshed but operated radially for some technical and financial concerns. Distribution networks can be represented with a graph in ordered pairs consisting of a set of vertices, i.e. buses and a set of edges, i.e. branches; in terms of mathematics this equivalents to a sparse matrix which its non-zero elements signifies the existence of an edge in the system. On this basis a typical distribution network is radial if it forms a tree where each load bus is exactly supplied

1.3.4. Introduction to graph theoretical analysis. The case of brain perfusion SPECT. In the field of quantitative neuroimaging, graph theoretical analysis is one of the methods to study brain connectivity [93-95, 100, 101]. A key concept of this method is the notion of topology. This concept can be illustrated with a simple idea which is used when we travel in the subway of any large city. In figure 3 two maps of the London subway appear, the first map shows a precise spatial description of the

presented in the algorithm that we have obtained via Local Search Algorithm for STP, we have generated the matrix of cost. This is done by assigning a cost to all the edges of tree SP and by assigning a cost on “n” no. of nodes to all the other edges in graph. This assignment of cost helps in recognizing the cost of the longest possible path between a pair of nodes in any spanning tree is n−1 (i.e. it passes n−1 edges) while the cost of the shortest path between any pair of nodes without using of SPT edges

Trees Authors: Amos Korman, Shay Kutten Problem Statement: A graph and a tree is given as input in a distributed manner and the algorithm is should be able to verifiy if the tree is a Minimum Spanning Tree (MST). Detailed Explanation of the Problem Statement Definitions Spanning tree: A spanning tree of an undirected graph is a subgraph which is a tree and includes all the vertices of G. Minimum Spanning Tree (MST) : A spanning tree of a graph whose weight (sum of weight of its edges) is less than or

data in many areas which can be modeled as graphs - entities (vertices/nodes) and their relationships (edges). They are increasingly being encountered in various fields of study. With this burst in data creation and collection, effective analysis of medium to large graphs is becoming increasingly popular in many fields such as social network analysis, biology, education, etc. With this increasing demand in large graph analytics, visual analysis of graphs has gained a lot of attention.

natural ingredients. Hair Coloring Market • There are two types of hair coloring. Semipermanent colors wash out after five or six shampooings. Permanent colors only disappear as the hair grows out from the roots. • Growth in unit volume over the last four years for both colorants has been 15% per year. • Both the increasing shares of the smaller brands and the decreasing shares of the leaders have sparked a 60% increase in advertising in 1989 for all brands of hair coloring. • Traditionally, hair colorants
