Quantitative performance-based evaluation of a procedure for flexible design concept generation
(Massachusetts Institute of Technology, 2011)
This thesis presents an experimental methodology for objective and quantitative design procedure evaluation based on anticipated lifecycle performance of design concepts, and a procedure for flexible design concept generation. ...
Understanding the impact of large-scale penetration of micro combined heat & power technologies within energy systems/
(Massachusetts Institute of Technology, 2011)
Significant energy challenges today come from security of supply and environmental concerns. Those surpass the quest for economic efficiency that has been the primary objective until recent times. In an intensive fossil-fuel ...
The climate impacts of high-speed rail and air transportation : a global comparative analysis
(Massachusetts Institute of Technology, 2012)
Growing concerns about the energy use and climate impacts of the transportation sector have prompted policymakers to consider a variety of options to meet the future mobility needs of the world's population, while ...
Technology investment decisions under uncertainty : a new modeling framework for the electric power sector
(Massachusetts Institute of Technology, 2013)
Effectively balancing existing technology adoption and new technology development is critical for successfully managing carbon dioxide (CO2) emissions from the fossil-dominated electric power generation sector. The long ...
The value of electricity storage under large-scale penetration of renewable energy : a hybrid modeling approach
(Massachusetts Institute of Technology, 2015)
Due to the physics of electricity, and the current high costs of storage technologies, electricity generation and demand need to be instantaneously balanced at all times. The large-scale deployment of intermittent renewables ...
Locating the source of large scale outbreaks of foodborne disease
(Massachusetts Institute of Technology, 2016)
Foodborne illness outbreaks impose enormous health and economic burdens in the US. Identifying the origin of the contaminated food causing an outbreak is a challenging problem due to the complexity of the food supply and ...
The cost of Jointness : insights from environmental monitoring systems in low Earth orbit
(Massachusetts Institute of Technology, 2015)
The term jointness refers to activities or operations that are executed collaboratively by more than one government agency or military department. While joint operations have become increasingly common and successful, the ...
Evaluating safety protocols for manned-unmanned environments through agent-based simulation
(Massachusetts Institute of Technology, 2014)
Recent advances in autonomous system capabilities have improved their performance sufficiently to make the integration of unmanned and autonomous vehicles systems into human-centered civilian environments a realistic ...
A decision analysis framework for the U.S. nuclear fuel cycle
(Massachusetts Institute of Technology, 2011)
If we are willing to pay a premium, we may be able to mitigate some of the long-lasting impacts of nuclear waste. Deciding how to navigate this tradeoff, between cost and waste, is a central challenge for stewards of nuclear ...
Innovation pathways in technology intensive government organizations : insights from NASA
(Massachusetts Institute of Technology, 2011)
Despite a rich legacy of impressive technological accomplishments (e.g., project Apollo, the Hubble Space Telescope) in recent years, the ability of government space agencies to deliver on their promises has increasingly ...
