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 ...
FairML : ToolBox for diagnosing bias in predictive modeling
(Massachusetts Institute of Technology, 2016)
Predictive models are increasingly deployed for the purpose of determining access to services such as credit, insurance, and employment. Despite societal gains in efficiency and productivity through deployment of these ...
A stochastic techno-economic comparison of alternative jet fuel production pathways
(Massachusetts Institute of Technology, 2017)
This study quantifies and compares the costs of production for six alternative jet fuel pathways using consistent financial and technical assumptions. Uncertainty was propagated through the analysis using Monte Carlo ...
Transfer learning for predictive models in MOOCs
(Massachusetts Institute of Technology, 2016)
Predictive models are crucial in enabling the personalization of student experiences in Massive Open Online Courses. For successful real-time interventions, these models must be transferable - that is, they must perform ...
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 ...
Decarbonization of power systems : analyzing different technological pathways
(Massachusetts Institute of Technology, 2016)
Climate change poses a major challenge to society. Different sectors of society will need to respond in different ways; for the power sector, the response will require the aggressive reduction of CO2 emissions to near zero ...
Effects of intermittent generation on the economics and operation of prospective baseload power plants
(Massachusetts Institute of Technology, 2017)
The electricity system is transitioning from a system comprised primarily of dispatchable generators to a system increasingly reliant on wind and solar power-intermittent sources of electricity with output dependent on ...
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 ...
Crushed rock thermal energy storage & nuclear technology : option space & economic impacts
(Massachusetts Institute of Technology, 2018)
Increasing amounts of intermittent renewables have led to zero and negative priced electricity at times of peak wind and solar production. The volatility added to the grid by renewables and low prices at peak production ...
Estimating hydrologic fluxes, crop water use, and agricultural land use in China from multiple data sources
(Massachusetts Institute of Technology, 2016)
Crop production has significantly altered the terrestrial environment by changing land use (Ramankutty et al., 2008) and by altering the water cycle through both co-opting rainfall and surface water withdrawals (Postel et ...
