System modeling, design, and control of the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) and implications for atmospheric ISRU processing plants
(Massachusetts Institute of Technology, 2017)
As humankind expands its footprint in the solar system, it is increasingly important to make use of Earth independent resources to make these missions sustainable and economically feasible. In-Situ Resource Utilization ...
Control of stochastically interacting systems on networks
(Massachusetts Institute of Technology, 2017)
The goal of this thesis is to develop control theoretic analysis and algorithms for characterizing and controlling stochastically interacting systems on networks. Such systems have three essential features - (i) they are ...
On-orbit inspection of a rotating object using a moving observer
(Massachusetts Institute of Technology, 2017)
Many objects in space such as orbital debris, defunct satellites, and natural objects are uncooperative, meaning that they are not equipped with working sensors or actuators. There are several reasons to want to visit these ...
Design as a search problem : interactive visualization for system design under uncertainty
(Massachusetts Institute of Technology, 2017)
Epoch Era Analysis (EEA) was developed to better model problems with lifecycle uncertainties and has demonstrated its usefulness in prior research studies, but it still faces significant challenges to practical application. ...
Predictive modeling and socially aware motion planning in dynamic, uncertain environments
(Massachusetts Institute of Technology, 2017)
Advances in sensor technologies and computing power have spurred a surge of interest in autonomous vehicles, such as indoor service robots and self-driving cars. The potential applications of such vehicles are predicted ...
Guidance and control for multi-stage rendezvous and docking operations in the presence of uncertainty
(Massachusetts Institute of Technology, 2017)
Rendezvous and docking missions have been a mainstay of space exploration from the Apollo program through present day operations with the International Space Station. There remains a growing interest in several mission ...
Towards Earth independence - tradespace exploration of long-duration crewed Mars surface system architectures
(Massachusetts Institute of Technology, 2016)
In recent years, an unprecedented level of interest has grown around the prospect of sending humans to Mars for the exploration and eventual settlement of that planet. With the signing of the 2010 NASA Authorization Act, ...
Experimental study of non-resolved active polarimetry for space surveillance
(Massachusetts Institute of Technology, 2016)
Man-made space debris constitutes a major threat to the future of the space enterprise. The space surveillance community continually seeks more efficient and robust techniques for detecting and characterizing on-orbit ...
A novel framework for acoustic diagnostic of artificial lift system for oil-production
(Massachusetts Institute of Technology, 2018)
Oil extraction on many reservoirs requires the use of rod pump systems to pump the fluid to the surface. A longstanding challenging issue in the operation of rod-pump system is the ability to determine the downhole pump ...
Data-driven modeling of air traffic flows for advanced Air Traffic Management
(Massachusetts Institute of Technology, 2018)
The Air Traffic Management (ATM) system enables air transportation by ensuring a safe and orderly air traffic flow. As the air transport demand has grown, ATM has become increasingly challenging, resulting in high levels ...
