Interface Design for Unmanned Vehicle Supervision through Hybrid Cognitive Task Analysis
(HFES, 2012-10)While there is currently significant interest in developing Unmanned Aerial Systems (UASs) that can be supervised by a single operator, the majority of these systems focus on Intelligence, Surveillance, and Reconnaissance (ISR) ... -
Intermodal air-surface movement of cargo John H. Mahoney.
(Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, [1980], 1980)Someone who told me he was a friend asked me to talk to you about "any single important aspect of air cargo" and the booby trap I suddenly stumbled into was the difficulty of sticking to a single subject from the many ... -
International aeronautical user charges
([Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, 1985], 1985)Introduction: 1.1 BACKGROUND AND MOTIVATION Very few issues relating to the international air transportation industry are today as divisive as those pertaining to user charges imposed at international airports and enroute ... -
International civil air transport : transition following WW II
(Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, 1979, 1979)International air transport, like many 20th Century marvels which are taken so much for granted today, broke out from its cocoon, so to speak, shortly after the end of World War II (WW II), took wing, and soared. Theretofore, ... -
Interplanetary space weather effects on Lunar Reconnaissance Orbiter avalanche photodiode performance.
(Space Weather: The International Journal of Research & Applications, 2016)Space weather is a major concern for radiation-sensitive space systems, particularly for interplanetary missions, which operate outside of the protection of Earth's magnetic field. We examine and quantify the effects of ... -
Interpolation Method for Update with Out-of-Sequence Measurements: The Augmented Fixed-Lag Smoother
