Stall propagation in axial compressors
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1955], 1955)
A theory of stall propagation in a cascade of airfoils of high solidity has been developed which includes the effects of finite blade chord and of the boundary layer response to changes in angle of attack. The theory is ...
A cascade tunnel for investigation of rotating stall
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1954], 1954)
A test apparatus which will reproduce the rotating stall phenomenon found in axial compressors has been constructed and installed in the main wind tunnel circuit of the Gas Turbine Laboratory. The test section consists of ...
Boundary layer separation ; preliminary report
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1962], 1962)
The phenomenon of incompressible boundary layer separation and the existing methods of predicting it are discussed. The failure of these theories in many cases clearly indicates a need for further investigation. A program ...
Supervised vs. Unsupervised Learning for Operator State Modeling in Unmanned Vehicle Settings
(Journal of Aerospace Computing, Information, and Communication, 2011)
In this paper, we model operator states using hidden Markov models applied to human supervisory control behaviors. More specifically, we model the behavior of an operator of multiple heterogeneous unmanned vehicle systems. ...
Human-Automation Collaboration in Complex Multivariate Resource Allocation Decision Support Systems
(International Journal of Intelligent Decision Technologies, 2010)
In resource allocation problems for systems with moving planning horizons and significant uncertainty, typical of supervisory control environments, it is critical that some balance of human-automation collaboration be ...
Effects of Single versus Multiple Warnings on Driver Performance
(2007)
Objective: To explore how a single master alarm system affects drivers’ responses when compared to multiple, distinct warnings. Background: Advanced driver warning systems are intended to improve safety, yet inappropriate ...
Gradient Projection Anti-windup Scheme on Constrained Planar LTI Systems
(2010-03-15)
The gradient projection anti-windup (GPAW) scheme was recently proposed as an anti-windup method for nonlinear multi-input-multi-output systems/controllers, the solution of which was recognized as a largely open problem ...
Exoplanet Albedo Spectra and Colors as a Function of Planet Phase, Separation, and Metallicity
(The Astrophysical Journal, 2010-11-20)
First generation space-based optical coronagraphic telescopes will obtain images of cool gas- and ice-giant exoplanets around nearby stars. Exoplanets lying at planet-star separations larger than about 1 AU—where an exoplanet ...
Air New England (1970-1974) : a case study of a commuter air carrier
(Cambridge, Mass. : Flight Transportation Laboratory, Massachusetts Institute of Technology, [1975], 1975)
This is a brief account of research by CAB staff. The success of Air New England from the beginning of its corporate life to the summer of 1974, when it was offered a certificate of public convenience and necessity by the ...
A systems analysis of scheduled air transportation networks
(Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, [1979], 1979)
This work establishes the conditions for airline system design building from submodels of smaller aspects of air transportation. The first three sections develop submodels which then are combined in extensive numerical ...
