The existence and behavior of ground-state and thermally-activated excitations in helium solids have been extensively examined by a variety of experimental and theoretical studies. Although these excitations are typically ...

The validity of a concept inventory is imperative to its adoption by the education community. In this thesis, we evaluate the validity of the Cybersecurity Concept Inventory for assessing student knowledge of core cybersecurity ...

Accurate representation of ice accretions is important to the study and understanding of aircraft icing. For research and certification purposes, replicas of ice accretions generated from icing wind tunnels are fabricated ...

A means for translating MCNP5 input files into a form that can be run by Mercury, a modern Monte Carlo particle transport code, will allow MCNP5 users to more easily take advantage of the high-performance computing benefits ...

Neuro-dynamic programming is a class of powerful techniques for approximating the solution to dynamic programming equations. In their most computationally attractive formulations, these techniques provide the approximate ...

The mechanism of vapor bubble detachment at zero gravity has been studied both analytically and numerically. Instead of analyzing the force balance, this study emphasizes momentum conservation, the time integral of the ...

Particle growth due to vapor scavenging was studied using both experimental and computational techniques. Vapor scavenging by particles is an important physical process in the atmosphere because it can result in changes ...

Novel vapor-liquid-equilibria data (P-T-x) and liquid densities of binary mixtures of an emerging low-GWP (Global Warming Potential) refrigerant, R-1234ze(E), and a polyol ester (POE) oil, RL68H, are measured. Data are ...
