Estimation of Real-Time Runway Surface Contamination Using Flight Data Recorder Parameters
<p>Within this research effort, the development of an analytic process for friction coefficient estimation is presented. Under static equilibrium, the sum of forces and moments acting on the aircraft, in the aircraft body coordinate system, while on the ground at any instant is equal to zero. Under …

Long term nitrate removal in a denitrification wall
… through enhancing microbial denitrification. One technology utilizing this microbial process is a denitrification wall, which is an inexpensive, low-maintenance technology compared to other options to treat NO3--contaminated groundwater. Denitrification walls have been shown to be effective for …
-
The Effect of Shift Turnover Strategy and Time Pressure on Aviation Maintenance Technician Performance
<p>Aviation maintenance technicians (AMTs) provide the technical and applied knowledge required to maintain airworthiness in aircraft. In commercial aviation, maintenance tasks are performed across multiple shifts. When AMTs share a maintenance task between shifts, the shift turnover strategy used …
-
Microbial community analysis for denitrifying biofilters
Denitrifying biofilters are a promising and low-maintenance technology for removing nitrate from agricultural drainage, capable of removing 50-80% of annual nitrate loads. Because increased riverine nitrate concentrations are correlated with indicators of eutrophy and degradation of coastal waters, …
