Robust hybrid control for autonomous vehicle motion planning
(Massachusetts Institute of Technology, 2001)
This dissertation focuses on the problem of motion planning for agile autonomous vehicles. In realistic situations, the motion planning problem must be solved in real-time, in a dynamic and uncertain environment. The ...
Fully kinetic numerical modeling of a plasma thruster
(Massachusetts Institute of Technology, 2001)
A Hall effect plasma thruster with conductive acceleration channel walls was numerically modeled using 2D3V Particle-in-Cell (PIC) and Monte-Carlo Collision (MCC) methodolo- gies. Electron, ion, and neutral dynamics were ...
Active noise control using glow discharge plasma panels
(Massachusetts Institute of Technology, 2001)
Managing subsystem commonality
(Massachusetts Institute of Technology, 2001)
Micropropulsion system selection for precision formation flying satellites
(Massachusetts Institute of Technology, 2001)
Integration of parent-child unmanned air vehicle focusing on control system development
(Massachusetts Institute of Technology, 2001)
As a part of PCUAV(Parent Child Unmanned Air Vehicle) project, the author participated in three areas. First, a study on the vehicle integration concept between a larger and two smaller UAVs are described. Various integration ...
Value stream analysis and mapping for product development
(Massachusetts Institute of Technology, 2001)
This thesis explores of Value Stream Analysis and Mapping (VSA/M) as applied to Product Development (PD) efforts. It contains three parts: the background and history of PD VSA/M, a report of the current PD VSA/M practices ...
New methodologies for onboard generation of Terminal Area Energy Management trajectories for autonomous reusable launch vehicles
(Massachusetts Institute of Technology, 2001)
Onboard trajectory generation capability greatly increases an autonomous reusable launch vehicle's capacity for recovering from unexpected disturbances or anomalous conditions. Such capability dispenses with the routine ...
High-accuracy foil optics for X-ray astronomy
(Massachusetts Institute of Technology, 2001)
Thermal design of a cooled micro gas turbine
(Massachusetts Institute of Technology, 2001)
One of the major challenges associated with designing a micro gas turbine engine is the problem of heat transfer. The demonstration version of the engine deals with this problem by transferring excess heat from the turbine, ...
