Norfolk Southern’s Machine Vision System Inspects Moving Rail Cars

To spot defects on moving trains, Norfolk Southern Railway (Atlanta, GA, USA) is building train inspection portals on tracks in the United States. The Georgia Tech Research Institute (Atlanta, GA, USA) is collaborating with the railroad on the inspection project.

The portals combine high-resolution cameras, stadium lights, and AI algorithms to capture and then analyze images of trains moving at up to 60 mph. All components are installed trackside inside tunnel-type steel structures.

Rapid Exchange Cooling With Trapped Ions For Implementation In A Quantum Charge-Coupled Device

A technical paper titled “Rapid exchange cooling with trapped ions” was published by researchers at Georgia Tech Research Institute.

“The trapped-ion quantum charge-coupled device (QCCD) architecture is a leading candidate for advanced quantum information processing. In current QCCD implementations, imperfect ion transport and anomalous heating can excite ion motion during a calculation. To counteract this, intermediate cooling is necessary to maintain high-fidelity gate performance...."
