2019 IEEE Aerospace Conference.
Almost fifty years ago, Dr. Robert Frosch, the fifth NASA administrator, delivered a speech on the practice of systems engineering and a call for improvement that remains relevant today. A key difference between the past and today is that the digital

Laser-Induced Incandescence (LII) occurs when a high-energy pulsed laser is used to heat soot to incandescent temperatures. Theoretical calculations predict and experimental tests demonstrate the resulting incandescence to be a measure of soot-volume
