Compared with abstract pure mathematical representation of a system and rough engineering drawings, the concept of bond graphs provide us a unique graphical view based on energy interactions among different domains. Bond graphs sit in the middle between equation sets and schematic block graphs, combining most of the advantages from both. The bond graph approach has already been shown to be effe...

In this paper we present a contribution to SysML for energy interchange depiction. This contribution consists of an extension to the activity diagram. We mapped it to the Bond Graph formalism which is often used for the design of mechatronic systems. We use the extension mechanisms that SysML inherits from UML2.0 such as stereotypes and tagged values to establish mapping rules from activities t...

A unified interface that can seamlessly merge real/virtual spaces or local/remote spaces are presented as a bi-directional energy interface. An arbitrary system consisted of real/virtual objects has some energy connections between the objects of the system. These energy connections can be simply described by bond graphs. Using the mathematical modeling derived from the bond graphs of the system...

By swapping out atoms for vertices and bonds edges, a graph may be used to model any molecular structure. A G is considered chemical in theory if no vertex of has degree 5 or greater. The bond incident (BID) index defined as the total contributions f(dG(u),dG(v)) from all edges uv G, where dG(w) stands w E(G) set f real-valued symmetric function. This paper addresses problem finding graphs with...
