Predicted response of microstructure, distortion, and residual stress in carburized steels cooled via oil and high intensity quenching

Daniel Baker & John Speer
Heat treatment simulations provide a new capability to understand and predict complicated responses, where thermal, mechanical, and microstructural effects are coupled. Simulations using DANTEĀ® compared the response of carburized and non-carburized 4120, 4320, and 8620 to oil and high intensity quenching. High intensity quenching involves high heat transfer rates and has the potential to reduce alloy content and carburization level compared to hot oil quenching. The simulations utilized a simple rod shape in order to...

Quasiparticle Spectrum of 2-d Dirac Vortices in Optical Lattices

Laith Haddad & Lincoln Carr
Bose-Einstein condensates (BEC's) in a honeycomb optical lattice are described by a nonlinear Dirac equaton (NLDE) in the long wavelength, mean field limit [1]. The bipartite structure of the lattice appears as pseudospin in the multi-component BEC with states above and below the Dirac point playing the roles of particles and antiparticles. Although much work has been done on NLDE's, the bulk of the literature deals with models with Poincare invariant nonlinearites. In contrast our...

Using Circuit-Level Power Measurements in Household Energy Management Systems

Alan Marchiori & Qi Han
The first requirement for any intelligent household energy management system is to be able to accurately measure energy usage in the home. Measuring energy usage is not difficult; however we must decide what to measure. Whole-home energy measurement is cheap and easy to setup because only one sensor is placed where the home connects to the power grid. The collected data can provide useful information for large appliances. However, the only way to monitor the...

Microstructure-Mechanical Property Relationships for Ni-Ti-Pt High Temperature Shape Memory Alloys

Grant Hudish & Michael Kaufman
Within the past decade, NASA has been developing high temperature shape memory alloys (HTSMAs) for use as simple, robust, and lightweight solid-state actuators. Shape memory alloys (SMAs) as actuators are considered nonconventional and advanced actuation devices and are capable of providing a power to weight ratio greater than that of DC motors, pneumatic systems, and comparable to that of hydraulic systems, in a much more compact and simplified geometry. Alloys of Ni and Ti in...

Quantum Many-body Tunneling of Bose-Einstein Condensates

Joseph Glick & Lincoln Carr
Consider the tunneling of a many-body wavefunction through a potential barrier. Specifically we examine quantum many-body tunneling of ultracold bosons in one dimensional optical lattice potentials. Such systems are described by the Bose-Hubbard model, and serve as an ideal testbed for the observation of quantum phenomena on macroscopic length scales. Bright solitons, self-sustaining nonlinear waves, are confined by a thin potential barrier. By decreasing the size of the barrier or by tuning the nonlinearity, we...

Transformation of the U.S.-ROK Alliance : balancing American strategic flexibility and South Korean modernization, The

Anthony Cerella & Elizabeth Davis
Even though the bilateral security alliance between South Korea and the United States is a product of Cold War it remains strategically significant for Korean and Northeast Asian stability. The alliance is currently changing as both the United States and South Korea are modifying their military strategies and structures. The United States is currently transforming its defense structure centering on the idea of strategic flexibility. Strategic flexibility involves reexamining and reallocating global force structures to...
