We developed a new chemical mechanism for modeling flame inhibition by 2-bromotrifluoropene (2-BTP). The modeling results qualitatively predicted agent behavior...
Despite the existence and interest in additive manufacturing (AM) for many decades, industry adoption of AM technologies has been relatively slow. Recent...
Small Arcane Nontrivial Datasets (SANDs) are frequently complex enough to warrant custom software for access and editing, yet too small or specialized to...
Heavier kerosene based liquid fuels for aircraft and rockets are required to meet stringent performance specifications. Nevertheless, the escalating cost...

A simulation study was conducted to evaluate indoor CO exposures as a function of portable generator location and CO emission rate in order to support the...
In this paper, we consider how high performing, sustainable building programs and designs are currently addressing indoor air quality (IAQ) and how they might...
It is common for electronic devices to be tested for their susceptibility to radiated signals they may be exposed to during their normal operation. A...
This is the third of a series of papers discussing various causes of measurement uncertainty in scanned particle beam instruments, and some of the solutions...
