This paper describes work in progress to analyze the cyber-physical resiliency of a microgrid when operated in islanded mode, as would be the case during an extreme event. The analysis must include each of the four components of a microgrid: sources

The article explores the relationship between Sobolev gradients and H -1 mixed methods for a variety of partial differential equations (PDEs) from image processing. A first-order system least-squares problem is used to introduce the method and compar

We examine the relationship of preconditioned L2 residual, Sobolev gradient and H−1 least squares methods. Of particular interest are: (1) a demonstration that the Sobolev gradient approach is simply a form of preconditioning for the standard L2 sc

This paper compares the use of first- and second-order Sobolev gradients to solve differential equations using the method of least-squares steepest descent. The use of high-order Sobolev gradients offers a very effective preconditioning strategy for
