Experiments in electroaerodynamic propulsion
(Massachusetts Institute of Technology, 2020)
Electroaerodynamic (EAD) propulsion, which produces a thrust force by electrokinetic acceleration of ions in air, is a proposed method of electric airplane propulsion that is solid-state, nearly silent, and produces no ...
Frequency stability in a compact, deployable optical atomic clock
(Massachusetts Institute of Technology, 2019)
The advent of ultra-narrow lasers, ultra-fast lasers, and optical frequency combs in the last several decades have enabled a new generation of atomic clocks based on optical transitions as opposed to microwave transitions ...
Deformation-assisted antifouling of surfaces
(Massachusetts Institute of Technology, 2020)
Fouling of surfaces occurs across many scales and applications, ranging from biomedical devices to ships, from membrane separation processes to ice formation on the wings of planes Chemical cleaning of the surfaces is often ...
A systems architecture framework towards hardware selection for autonomous navigation
(Massachusetts Institute of Technology, 2019)
The inclusion of autonomous vehicles into our transportation networks requires methods for evaluation and certification of systems on the vehicle. Adding sensors or computing capabilities to the vehicle might improve ...
Towards fuel-efficient formation flying of an observatory and external occulter at Sun-Earth L2
(Massachusetts Institute of Technology, 2020)
The prolific discovery of habitable zone residing exoplanets via indirect detection methods have spurred many in the astrophysics and space technology community to call for the prioritization of funding for a direct exoplanet ...
Electro-aerodynamic thrust for fixed-wing aircraft propulsion
(Massachusetts Institute of Technology, 2017)
Aviation operations negatively impact global climate, degrade surface air quality, and create noise. Towards mitigating these effects, this thesis considers electro-aerodynamic (EAD) propulsion, a form of in-atmosphere ...
Human-machine collaborative optimization via apprenticeship scheduling
(Massachusetts Institute of Technology, 2017)
I envision a future where intelligent service robots become integral members of human-robot teams in the workplace. Today, service robots are being deployed across a wide range of settings; however, while these robots ...
Safety-driven early concept analysis and development
(Massachusetts Institute of Technology, 2015)
As aerospace systems become increasingly complex and the roles of human operators and autonomous software continue to evolve, traditional safety-related analytical methods are becoming inadequate. Traditional hazard analysis ...
Truncated Bayesian nonparametrics
(Massachusetts Institute of Technology, 2016)
Many datasets can be thought of as expressing a collection of underlying traits with unknown cardinality. Moreover, these datasets are often persistently growing, and we expect the number of expressed traits to likewise ...
Cow-path games : tactical strategies to search for scarce resources
(Massachusetts Institute of Technology, 2015)
This thesis investigates search scenarios in which multiple mobile, self-interested agents, cows in our case, compete to capture targets. The problems considered in this thesis address search strategies that reflect (i) ...
