Experimental modeling of EVA tasks and workload using force-torque sensing apparatus
(Massachusetts Institute of Technology, 1990)
Integral boundary layer heat transfer prediction on turbine blades
(Massachusetts Institute of Technology, 1990)
Fast visual recognition of large object sets
(Massachusetts Institute of Technology, 1990)
Head-up display symbology for ground collision avoidance
(Massachusetts Institute of Technology, 1999)
Four predictive ground collision avoidance displays (Break-X, Chevrons, Mountain, and Highway) were tested using a fixed-base T-38 simulator with a projection screen and simulated Head-Up Display (HUD). The Break-X was ...
Analysis, fabrication and testing of a MEMS-based micropropulsion system
(Massachusetts Institute of Technology, 1999)
Various trends in the spacecraft industry are driving the development of low-thrust propulsion systems. These may be needed for fine attitude control, or to reduce the mass of the propulsion system through the use of small ...
Active control of rotating stall in a three-stage axial compressor with jet actuators
(Massachusetts Institute of Technology, 1997)
Reduced DoD product development time : the role of the schedule development process
(Massachusetts Institute of Technology, 1999)
According to the Packard Commission, "Unreasonably long acquisition cycles -- ten to fifteen years for major weapon systems is a central problem from which most other acquisition Problems stem." Since the commission issued ...
Design, manufacturing, and testing of an active twist rotor
(Massachusetts Institute of Technology, 1999)
An Active Twist Rotor (ATR) is developed for future implementation of the individual blade control for vibration and noise reduction in helicopters. The rotor blade is integrally twisted by direct strain actuation using ...
Closed-loop depth and attitude control of an underwater relerobotic vehicle
(Massachusetts Institute of Technology, 1990)
Scheduling of costly measurements for state estimation using reinforcement learning
(Massachusetts Institute of Technology, 1999)
There has long been a significant gap between the theory and practice of measurement scheduling for state estimation problems. Theoretical papers tend to deal rigorously with small-scale, linear problems using methods that ...
