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.

Bernoulli (bond) percolation on complete graphs is an example of a random graph. The critical probability is p = 1 / N , where N is the number of vertices (sites) of the graph. Bootstrap percolation removes active cells from clusters when they have too few active neighbors, and looks at the connectivity of the remaining cells. [20]
The kinematics and dynamics of the Jansen mechanism have been exhaustively modeled using circle intersection method and bond graphs (Newton–Euler mechanics). [6] These models can be used to rate the actuator torque and in design of the hardware and controller for such a system.
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 ]
The method was then generalised to handle any holonomic constraint, such as those required to maintain constant bond angles, or molecular rigidity. [ 11 ] In SHAKE algorithm, the system of non-linear constraint equations is solved using the Gauss–Seidel method which approximates the solution of the linear system of equations using the Newton ...
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 ...
