In particular, a novel application of optimal grids to perfectly matched layer absorbing boundary conditions is presented. In this development, a single optimal grid combining the interior computational and exterior absorbing ...

The goal of this thesis is to demonstrate the applicability of the discrimination time optimization problem to space systems. The concept is applied to an asteroid interception problem using low-thrust propulsion and solved ...

A triangulation in the plane is a maximal connected plane graph with straight edges. It is thus a plane graph whose bounded faces are triangles. For a fixed set of vertices, there are, in general, exponentially many ways ...

The future direction of aviation security system design involves creating a system of systems with layers of protection, and exhibits flexibility to quickly protect against new threats. This dissertation provides methodologies ...

Unregulated concurrency in functional programs may lead to space demands that exceed available space, causing deadlock. This thesis proposes regulating concurrency optimistically with rollbacks. Excessive concurrency is ...
