Active control of distributed structures
… control forces. The class of self-adjoint systems are first considered following a treatment of non-self-adjoint systems. Numerical examples of a beam, a membrane and a whirling shaft are presented. In general, the eigenquantities for a distributed structure cannot be computed in …

Efficient Computational Tools for Variational Data Assimilation and Information Content Estimation
… more challenging. The construction of an adjoint model ( capable of efficiently computing sensitivities of a few model outputs with respect to many input parameters ) is a difficult, labor intensive, and error prone task. This work develops adjoint systems for two of the most widely used …

A Modified Preconditioned Conjugate Gradient Method for Approximating the Scattering Amplitude
… amplitude that involves solving two linear systems: a forward system A<strong>x</strong>=<strong>b</strong> and an adjoint system A<sup>T</sup><strong>y</strong>=<strong>g</strong>. Once these two systems are solved, the scattering amplitude, defined by …
