A Graph-Theory-Based Method for Topological and Dimensional Representation of Planar Mechanisms as a Computational Tool for Engineering Design

Abstract: In this paper, a graph-theory-based approach for representing planar mechanisms is presented, the Santiago Portilla method (SPM). From the corresponding adjacency matrix, SPM generates an ...

Maximal Planar Graphs As Topological Authentications For Asymmetric Encryption

Abstract: We, for asymmetric encryption, introduce colored topological authentication, Topcode-matrix authentication, cycle-coinciding operation, planar rhombus ...
