Quantitative nondestructive density determinations of very low-density carbon foams

Description: The carbon density and the carbon distribution in low-density foams that were manufactured by a modified salt-replica process were determined by bulk measurements of weight and volume and by x-ray computed tomography (CT). When determining the carbon density, both methods yielded similar results, however, the high spatial resolution of CT was found to yield nondestructive quantitative information on the carbon distribution that was not available from bulk measurements. The highest and lowest fo… more

Atomic weight versus atomic mass controversy

Description: A problem for the Atomic Weights Commission for the past decade has been the controversial battle over the names ''atomic weight'' and ''atomic mass''. The Commission has considered the arguments on both sides over the years and it appears that this meeting will see more of the same discussion taking place. In this paper, I review the situation and offer some alternatives.

Error Reduction for Weigh-In-Motion

Description: Federal and State agencies need certifiable vehicle weights for various applications, such as highway inspections, border security, check points, and port entries. ORNL weigh-in-motion (WIM) technology was previously unable to provide certifiable weights, due to natural oscillations, such as vehicle bouncing and rocking. Recent ORNL work demonstrated a novel filter to remove these oscillations. This work shows further filtering improvements to enable certifiable weight measurements (error < 0.1… more

Construction and testing of advanced ceramic fabric radiator components to 1000 K

Description: For a number of years, the authors have been studying the application of advanced ceramic fabric materials to spacecraft heat rejection systems. Their studies indicated that significant mass and launch volume savings could be realized through such application, but concrete evidence to support this contention was lacking. Last year they presented preliminary test data that supported their claims (Antoniak and Webb 1989). Recent pressure, heat transfer, and wicking tests and analyses confirm the … more

Development of polymer concrete vaults for natural gas regulator stations

Description: Vaults for natural gas regulator stations have traditionally been fabricated with steel-reinforced portland cement concrete. Since these vaults are installed below ground level, they are usually coated with a water-proofing material to prevent the ingress of moisture into the vault. In some cases, penetrations for piping that are normally cast into the vault do not line up with the gas lines in the streets. This necessitates off-setting the lines to line up with the penetrations in the vault or… more
