Final Technical Report for "Applied Mathematics Research: Simulation Based Optimization and Application to Electromagnetic Inverse Problems"
The focus of research was: Developing adaptive mesh for the solution of Maxwell's equations; Developing a parallel framework for time dependent inverse Maxwell's equations; Developing multilevel methods for optimization problems with inequality constraints; A new inversion code for inverse Maxwell's equations in the 0th frequency (DC resistivity); A new inversion code for inverse Maxwell's equations in low frequency regime. Although the research concentrated on electromagnetic forward and in- verse problems the results of the research was applied to the problem of image registration.
JWL in a Nutshell
The Jones-Wilkins-Lee (JWL) equation of state is an analytical equation of state (EOS) used in the modeling of detonation products of high explosives. The JWL parameters for typical explosives are found in a series of reports by Brigitta Dobratz. The JWL parameters are usually derived from thermochemical codes or experimental cylinder tests using an elaborate and arcane procedure. It is often said that the JWL parameters need to be “self-consistent”, “thermodynamically consistent”, or “consistent with the conservation laws of mass, momentum, and energy.” The purpose of this document is to explain and illuminate what that means. Each parameter in the JWL equation of state is connected to the other parameters. An ideal simulation would produce detonation products at the Chapman-Jouguet state. I begin by describing the form of this equation of state.
