Enhancing astronaut mobility through spacesuit kinematics and interactive space outreach
(Massachusetts Institute of Technology, 2016)
Human spaceflight programs are facing new challenges rising from the evolution of the exploration agenda, as well as the changing international panel of actors. Planetary exploration missions will require intensive ...
Analysis of potential implementations of pushback control at LaGuardia Airport
(Massachusetts Institute of Technology, 2015)
Implementations of surface traffic management strategies at congested airports have the potential to yield significant benefits, but must account for the constraints and objectives of multiple stakeholders. This thesis ...
Systems-level analysis of On Demand Mobility for aviation
(Massachusetts Institute of Technology, 2017)
On Demand Mobility (ODM) is an emerging transportation concept that leverages pervasive telecommunication connectivity to enable the real-time matching of consumers with transportation service providers. Having experienced ...
Assessing and mitigating vulnerability chains in model-centric acquisition programs
(Massachusetts Institute of Technology, 2018)
Acquisition programs increasingly use model-centric approaches, generating and using digital assets throughout the lifecycle. Model-centric practices have matured, yet in spite of sound practices there are uncertainties ...
Design for affordability in defense and aerospace systems using tradespace-based methods
(Massachusetts Institute of Technology, 2014)
Program failures have plagued the defense and aerospace industry for decades, as unanticipated cost and schedule overruns have rendered the development of systems ineffective in terms of time and cost considerations. This ...
Modernizing systems engineering : cognitive systems and model-based approaches for spacecraft architecture development
(Massachusetts Institute of Technology, 2014)
Systems engineering exists as a discipline to enable organizations to control and manage the development of complex hardware and software. These methods are particularly essential in the development of space systems, which ...
Public health impacts of excess NOx̳ emissions from Volkswagen diesel passenger vehicles in Germany
(Massachusetts Institute of Technology, 2017)
In September 2015, the Volkswagen Group (VW) admitted the use of "defeat devices" designed to lower emissions measured during VW vehicle testing for regulatory purposes. Globally, 11 million cars sold between 2008 and 2015 ...
Emergence of second-generation low earth orbit satellite constellations : a prospective technical, economic, and policy analysis
(Massachusetts Institute of Technology, 2018)
Modern proposals for Low Earth Orbit (LEO) satellite constellations underscore the tremendous potential and versatility of distributed spacecraft missions (DSMs), but they have also begun to stress the limits of the existing ...
