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 ...
Henry Martyn Paynter IV was born in Evanston, Illinois and grew up in New York City and its environs. He received the B.S. in civil engineering in 1944, the M.S. in mathematics and science in 1949, and the first Sc.D. ever awarded in hydroelectric engineering in 1951, all from MIT.
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.

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 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 ...
The σ from the 2p is more non-bonding due to mixing, and same with the 2s σ. This also causes a large jump in energy in the 2p σ* orbital. The bond order of diatomic nitrogen is three, and it is a diamagnetic molecule. [12] The bond order for dinitrogen (1σ g 2 1σ u 2 2σ g 2 2σ u 2 1π u 4 3σ g 2) is three because two electrons are now ...
