A micro- and macro- analysis of human-machine interfaces and systems in space
(Massachusetts Institute of Technology, 2019)
Humans and machines interact with each other on a variety of scales. Interactions can involve tightly coupled interfaces or even be socio-technical in nature. In terms of large complex systems, humans learn to interact and ...
A methodology for identifying flexible design opportunities
(Massachusetts Institute of Technology, 2008)
Technical and operational uncertainties dynamically change environments for engineering systems. Flexibility allows systems to continue delivering value as the uncertainty unfolds. Uncertainty can better be managed by ...
An assessment of the health implications of aviation emissions regulations
(Massachusetts Institute of Technology, 2008)
An exploration of the health implications of aviation emissions regulations is made by assessing the results of a study of aviation's effects on United States air quality mandated by the Energy Policy Act of 2005. The ...
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 ...
An analysis method for conceptual design of complexity and autonomy in complex space system architectures
(Massachusetts Institute of Technology, 2001)
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 ...
Technical and policy considerations of sensor-Based decision aids
(Massachusetts Institute of Technology, 2020)
The design and operation of complex systems requires methods for decision makers to evaluate the relative merit of alternative options and the implications that choosing one of those options will have. In order for a ...
On-orbit serviceability of space system architectures
(Massachusetts Institute of Technology, 2006)
On-orbit servicing is the process of improving a space-based capability through a combination of in-orbit activities which may include inspection; rendezvous and docking; and value-added modifications to a satellite's ...
