A bond graph is a graphical representation of a physical dynamic system. It allows the conversion of the system into a state-space representation . It is similar to a block diagram or signal-flow graph , with the major difference that the arcs in bond graphs represent bi-directional exchange of physical energy , while those in block diagrams ...
The Bond graph modelling approach was presented for the first time in the "Ports, Energy and Thermodynamic Systems" on April 24, 1959, at MIT, which was later published (Paynter, 1961). Paynter was elected to the National Academy of Engineering in 1997, one of the highest professional distinctions accorded to an engineer.

As the bond angle is distorted, the energy for each of the orbitals can be followed along the lines, allowing a quick approximation of molecular energy as a function of conformation. It is still unclear whether or not the Walsh ordinate considers nuclear repulsion, and this remains a topic of debate. [ 21 ]
A dipole graph containing n edges is called the size-n dipole graph, and is denoted by D n. The size-n dipole graph is dual to the cycle graph C n. The honeycomb as an abstract graph is the maximal abelian covering graph of the dipole graph D 3, while the diamond crystal as an abstract graph is the maximal abelian covering graph of D 4.
Based on the covalent bond classification method (from where LBN is derived), the equation for determining ligand bond number is as follows: LBN = L + X + Z. Where L represents the number of neutral ligands adding two electrons to the metal center (typically lone electron pairs, pi-bonds and sigma bonds. Most encountered ligands will fall under ...
A hybrid bond graph is a graphical description of a physical dynamic system with discontinuities (i.e., a hybrid dynamical system). Similar to a regular bond graph, it is an energy-based technique. However, it allows instantaneous switching of the junction structure, which may violate the principle of continuity of power (Mosterman and Biswas ...
