There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Engineers Merge Technologies to Improve Inspection of Wooden Pow
Full Summary:
Researchers from ECE and the Georgia Tech Research Institute are merging two technologies that are expected to reduce costs and increase the accuracy of inspecting millions of wooden crossarms that hold up power lines worldwide.
Engineers working to improve wooden power polesResearchers from ECE and the Georgia Tech Research Institute are merging two technologies that are expected to reduce costs and increase the accuracy of inspecting millions of wooden crossarms that hold up power lines worldwide.
Susceptible to rot, wooden crossarms must be inspected and replaced periodically, or otherwise lines could collapse and cause outages. Such inspections have traditionally required workers to climb poles, hit the crossarm with a hammer and judge its condition by listening to the resulting ring. But these manual inspections are imprecise, time-consuming, costly, and hazardous.
Now, researchers have merged laser vibrometry and neural networks to create a remote inspection system that analyzes crossarms from the air. The team includes ECE Professor Ron Harley, NEETRAC research engineer Paul Springer, and GTRI research engineer Jim Mahaffey.
