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 ...

Simulation of the transient stability problem of a power system, which is the assessment of the short term angular and voltage stability of the system following a disturbance, is of vital importance. It is widely known in ...

The primary objective of this study was to develop and demonstrate a rational procedure for the establishment of pavement construction pay adjustment schedules. A rational procedure was defined as one that would reflect ...

As power systems evolve, integration of renewable energy, lightweight-turbine generators and other electronic devices result in: 1) less inertia and maybe worse primary frequency responses (from transient stability perspective ...

The use of InGaAsP alloys for optical fiber communication systems is discussed. The advantages and various types of vapor phase epitaxial growth systems are examined before looking at the open tube growth process in detail. ...

Vapor-liquid equilibria (VLE) data were obtained over a wide range of mixture composition and saturation conditions for difluoromethane (R-32) mixed with a polyol ester oil (POE). These data were correlated using the ...
