Approaching ideal weak link behavior with three dimensional aluminum nanobridges

Dynamic Behavior of a Three Dimensional Aluminum Truss

The United States Navy sponsored Truss Damping Program is a research study in the area of submarine noise reduction. The research explores the feasibility of effectively attenuating noise associated with vibration of rotating machinery by means of a truss support structure. Such a structure occupies the entire machinery space by supporting all internal equipment. This thesis explores the dynami...

Approaching Ideal NoC Latency with Pre-Configured Routes Master’s Thesis

In multi-core ASICs, processors and other compute engines need to communicate with memory blocks and other cores with latency as close as possible to the ideal of a direct buffered wire. However, current state of the art networks-on-chip (NoCs) suffer, at best, latency of one clock cycle per hop. We investigate the design of a NoC that offers close to the ideal latency in some preferred, run-ti...

Non-ideal MHD ballooning modes in three-dimensional configurations

A linear stability theory of non-ideal MHD ballooning modes is investigated using a two fluid model for arbitrary three-dimensional electron-ion plasmas. Resistive-inertia ballooning mode (RIBM) eigenvalues and eigenfunctions are calculated for a variety of equilibria including axisymmetric shifted circular geometry (s − α model) and configurations of interest to the Helically Symmetric Stellar...

Normal forms for three-dimensional parametric instabilities in ideal hydrodynamics

We derive and analyze several low dimensional Hamiltonian normal forms describing system symmetry breaking in ideal hydrodynamics. The equations depend on two parameters (e,2), where e is the strength of a system symmetry breaking perturbation and 2 is a detuning parameter. In many cases the resulting equations are completely integrable and have an interesting Hamiltonian structure. Our work is...
