... rise to two different dual graphs. Sohn and Freudenstein [4] applied the concept of dual graphs for the development of an automated procedure for the enumeration of the kinematic structures of ... end vertices, it contributes 2 to the sum of the degrees of the vertices. Therefore, the sum of the degrees of all vertices in a graph is equal to twice the number of e...
