Hazard detection with VHDL in combinational logic circuits with fixed delays
Timing hazards are common problems found in logic circuits. A new integrated hazard detection system (HDS), which is implemented in VHDL, is proposed to detect the static, the dynamic, and the function hazards in any logic circuit that is described structurally in VHDL. This system adopts the IEEE …

Electrical interaction between atmospheric volcanic ash and aircraft in flight : mechanisms and application for hazard detection
… ash suspended within dispersed plumes has been a hazard to aviation since the advent of commercial jet airliners in the 1960s. This study examines the interaction of volcanic ash particles with metallic surfaces likely to be found on an aircraft, and its ability to charge those surfaces by impact. …
