Human-spacesuit interaction :
(Massachusetts Institute of Technology, 2015)
Extravehicular activities (EVA), or space walks, are a critical and complex aspect of human spaceflight missions. To prepare for safe and successful execution of the required tasks, astronauts undergo extensive training ...
Automated synthesis of low-rank stochastic dynamical systems using the tensor-train decomposition
(Massachusetts Institute of Technology, 2016)
Cyber-physical systems are increasingly becoming integrated in various fields such as medicine, finance, robotics, and energy. In these systems and their applications, safety and correctness of operation is of primary ...
Automation techniques for short interval scheduling in a complex manufacturing environment
(Massachusetts Institute of Technology, 2016)
Aircraft Company X (ACX) designs and manufactures aircraft. ACX operates Manufacturing Center 1 which produces parts and assemblies for both assembly and spares business lines. Accurate scheduling is crucial for meeting ...
A hybridized discontinuous Galerkin formulation for modeling electrohydrodynamic thrusters
(Massachusetts Institute of Technology, 2015)
Electrohydrodynamic (EHD) thrusters utilize ion neutral collisions in air to produce a propulsive force. The ions are generated at an emitting electrode in an asymmetric capacitor by a corona discharge. This thesis presents ...
Equitable resource allocation using all-pay auctions
(Massachusetts Institute of Technology, 2011)
Auction theory is a very interesting topic which studies mechanisms of various formats for buying and selling goods. There are all kinds of mechanisms covered in the ambit of auction theory, ranging from sealed bid auctions ...
Analysis and modeling of airport surface operations
(Massachusetts Institute of Technology, 2011)
The focus of research in air traffic control has traditionally been on the airborne flight phase. Recently, increasing the efficiency of surface operations has been recognized to have significant potential benefits in terms ...
Modeling operator performance in low task load supervisory domains
(Massachusetts Institute of Technology, 2011)
Currently, numerous automated systems need constant monitoring but require little to no operator interaction for prolonged periods, such as unmanned aerial systems, nuclear power plants, and air traffic management systems. ...
Acquisition strategies for commonality across complex aerospace systems-of-systems
(Massachusetts Institute of Technology, 2011)
Commonality is a system architecting strategy widely used to improve affordability and reliability of families of products. However not all commonality is beneficial, and organizations must balance commonality benefits and ...
Development and evaluation of a collision avoidance system for supervisory control of a micro aerial vehicle
(Massachusetts Institute of Technology, 2012)
Recent technological advances have enabled Unmanned Aerial Vehicles (UAVs) and Micro Aerial Vehicles (MAVs) to become increasingly prevalent in a variety of domains. From military surveillance to disaster relief to ...
An improved blade passage model for estimating off-design axial compressor performance
(Massachusetts Institute of Technology, 2013)
Accurate estimates of multistage axial compressor performance at off-design operating conditions are essential to the determination of key performance metrics of aircraft gas turbine engines, such as fuel burn, thrust ...
