Massively Parallel Solver for the High-Order Galerkin Least-Squares Method
(Aerospace Computational Design Laboratory, Dept. of Aeronautics & Astronautics, Massachusetts Institute of Technology, 2009-06)
A high-order Galerkin Least-Squares (GLS) finite element discretization is combined
with massively parallel implicit solvers. The stabilization parameter of the GLS
discretization is modified to improve the resolution ...
Characterization of a semidiurnal eastward-propagating tide at high northern latitudes with Mars Global Surveyor electron density profiles
(American Geophysical Union, 2007-08-03)
Apparent phase velocities of zonal structure, estimated from Mars Global Surveyor (MGS) electron density profiles, are used to identify and characterize SE1, the semidiurnal eastward-propagating tide with zonal wave number ...
Design and Evaluation of Path Planning Decision Support for Planetary Surface Exploration
(Journal of Aerospace Computing, 2008)
Human intent is an integral part of real-time path planning and re-planning, thus any decision aiding system must support human-automation interaction. The appropriate balance between humans and automation for this task ...
The Impact of Multi-layered Data-blocks on Controller Performance
(Air Traffic Control Quarterly, 2008)
As a consequence of the push to increase National Airspace System capacity, air traffic control displays will not only have to show the increasing number of aircraft, but also all the associated data such as airspeed and ...
Parametric dependencies of aeroengine flutter for flutter clearance applications
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [2000], 2000)
This thesis describes the effects of operational parameters upon aeroengine flutter stability. The study is composed of three parts: theoretical development of relevant parameters, exploration of a computational model, and ...
High Order Finite Element Discretization of the Compressible Euler and Navier-Stokes Equations
(Aerospace Computational Design Laboratory, Dept. of Aeronautics & Astronautics, Massachusetts Institute of Technology, 2001-04)
We present a high order accurate streamline-upwind/Petrov-Galerkin (SUPG) algorithm for the solution of the compressible Euler and Navier-Stokes equations. The flow equations are written in terms of entropy variables which ...
Cognitive Task Analysis for the LCS Operator
(MIT Humans and Automation Laboratory, 2006)
The following Tables and Figures detail the cognitive task analysis (CTA) performed to
determine the information requirements needed to support a single operator located aboard the
futuristic Littoral Combat Ship (LCS). ...
Selecting Metrics to Evaluate Human Supervisory Control Applications
(MIT Humans and Automation Laboratory, 2008)
The goal of this research is to develop a methodology to select supervisory control metrics. This
methodology is based on cost-benefit analyses and generic metric classes. In the context of this research,
a metric class ...
An Intelligent Cooperative Control Architecture
(AIAA, 2009-10-07)
This paper presents an extension of existing cooperative control algorithms that have been developed for multi-UAV applications to utilize real-time observations and/or performance metric(s) in conjunction with learning ...
Past, Present And Future Implications Of Human Supervisory Control In Space Missions
(Acta Astronautica, 2008)
Achieving the United States’ Vision for future Space Exploration will necessitate far greater collaboration between humans and automated technology than previous space initiatives. However, the development of methodologies ...
