Crew Training Requirements For Long Duration Missions
<p>After reviewing the journals of astronauts, cosmonauts, and others who lived and worked in confinement, a new pre-mission training approach for missions in confinement was developed. This new training approach is founded on the idea that conflicts in confinement often arise due to humanity's …

Fuzzy Analysis of Speech Metrics to Estimate Crew Alertness
A novel approach for estimating alertness levels from speech and tagging them with a reliability component has been developed. The Fatigue Quotient and Believability are both derived from the time series analysis of the speech signal in the communication between the operator and dispatch. Operator …
