| The first step in solving such equations by the variational method is to show that the extremum is attained. |
| Both element and global force-displacement equations are developed using both the variational and direct stiffness methods. |
| This paper proposes a novel probabilistic variational method with deterministic annealing for the maximum a posteriori estimation of complex stochastic systems. |
| He developed variational techniques that produced major advances in several fields of mathematical physics. |
| When astronomers talk about the evolution of a star, they clearly do not have a variational theory like Darwin's in mind. |
| Celestial mechanics is the origin of dynamical systems, linear algebra, topology, variational calculus and symplectic geometry. |
