WebAbstract: It is shown how the Hamiltonian equations for a ray in an anisotropic medium can be used on an electronic computer to calculate ray paths in three dimensions in a model … WebThere is an even more powerful method called Hamilton’s equations. It begins by defining a generalized momentum p i , which is related to the Lagrangian and the generalized velocity q̇ i by p i = ∂ L /∂ q̇ i . A new function, the Hamiltonian, is then defined by H = Σ i q̇ i p i − L. From this point it is not difficult to derive and.

WebWith a non-zero Hamiltonian, the dynamics itself (through the conserved Hamiltonian) showed that the appropriate parameter is path length. 3 Separating Time and Space The Hamiltonian formalism developed above is elegant and manifestly covariant, i.e. the results are tensor equations and therefore hold for any coordinates and any reference frame. WebThe system can be described in Hamiltonian viewpoint with Hamiltonian and con-straints in phase space H(p;q; ) = pq_ L(q;q_) + jak(q ... Only paths that satisfy the constraints are allowed when minimizing the path to derive the equations of motion.

In the mathematical field of graph theory, a Hamiltonian path (or traceable path) is a path in an undirected or directed graph that visits each vertex exactly once. A Hamiltonian cycle (or Hamiltonian circuit) is a cycle that visits each vertex exactly once. A Hamiltonian path that starts and ends at adjacent vertices can be completed by adding one more edge to form a Hamiltonian cycle, and remo… WebThe Hamiltonian ray path equations.

"WebUsing a formulation based on Hamilton's ray equations, the variations of the path of a ray, and of the corresponding phase path, due to changes in the ray end points or the medium properties, are investigated. General expressions are obtained which represent the variations in terms of the solution of systems of ordinary differential equations. " - The hamiltonian ray path equations
