... correspondence between a conventional graph and its dual as follows: (1) the vertices of a dual graph correspond to the loops of a conventional graph, (2) the loops of a dual graph correspond to ... are encouraged to refer to Gibsons [1] and Harary [2] for more detailed descriptions of the theory. 2.1 Deﬁnitions A graph consists of a set of vertices (points) together with a set of edges or ... vertex j  and then converge at vertex k  . Then, that section of P from j  to k  and that section of Q from j  to k  form a circuit. This leads to a contradiction since T contains no circuit....

... the nature of connection among various links of a kinematic chain is called the structural analysis or topological analysis. To facilitate the analysis, several methods of representation of the ... capable of converting the rotational motion of link 2 into the reciprocating and oscillatory motions of link 4. These two mechanisms are different in physical embodiment, but their structural topologies ... graph representation, the vertices denote links and the edges denote joints of a mechanism. The edge connection between vertices corresponds to the pair connection between links. To distinguish...

... direction of rotation, z i -axis, is assigned to each joint axis of an epicyclic gear train. For planar gear trains, it is most convenient to deﬁnethe positive direction of rotation of all gears to ... gears are connected to each other by a common shaft, whereas the carrier of one basic PGT is connected to the ring gear of the other PGT by a spline shaft. Overall, it forms a one-dof mechanism. ... graph of n vertices. However, some of the graphs may be rejected due to violation of the structural characteristics, whereas others may be isomorphic to one another. Hence, the total number of nonisomorphic unlabeled...
