Addressing design challenges in mechanical counterpressure spacesuit design and space-inspired informal education policy
(Massachusetts Institute of Technology, 2011)
Extravehicular activity (EVA), or spacewalks allows astronauts to accomplish some of the most important endeavors in space history. The importance of EVA will continue to increase as people venture further into our solar ...
Stakeholder value network analysis for space-based earth observations
(Massachusetts Institute of Technology, 2009)
The Earth Science and Applications decadal survey released by the National Research Council in 2007 presents both an ambitious engineering challenge and a challenge for the entire Earth science community to come together ...
A comparison of cost-containment instruments for US carbon reduction policies
(Massachusetts Institute of Technology, 2008)
A cap-and-trade program, as is used in the European Trading Scheme, is currently the most widely discussed method in the US for reducing greenhouse gases. A basic cap-and-trade program operates by mandating a fixed level ...
Improving understanding of climate change dynamics using interactive simulations
(Massachusetts Institute of Technology, 2008)
Global climate change is one of the most complex problems that human kind will face during the 21st century. Long delays in changing greenhouse gas emissions and in the response of the climate to anthropogenic forcing mean ...
VacSeen : semantically enriched automatic identification and data capture for improved vaccine logistics
(Massachusetts Institute of Technology, 2016)
Vaccines are globally recognized as a critical public health intervention. Routine immunization coverage in large parts of the developing world is around 80%. Technology and policy initiatives are presently underway to ...
Policies for parking pricing derived from a queueing perspective
(Massachusetts Institute of Technology, 2009)
Drivers in urban neighborhoods who cruise streets, seeking inexpensive on-street parking create a significant fraction of measured traffic congestion. The solution to this problem is to reduce the total traffic volume ...
Characterizing shale gas and tight oil drilling and production performance variability
(Massachusetts Institute of Technology, 2015)
Shale gas and tight oil are energy resources of growing importance to the U.S. and the world. The combination of horizontal drilling and hydraulic fracturing has enabled economically feasible production from these resources, ...
Strategic philanthropy for cyber security : an extended cost-benefit analysis framework to study cybersecurity
(Massachusetts Institute of Technology, 2012)
The international climate of cyber security is dramatically changing and thus unpredictable. As such, agile yet sustainable solutions are needed, along with an effective and a pragmatic evaluation framework to assess and ...
Plant power : the cost of using biomass for power generation and potential for decreased greenhouse gas emissions
(Massachusetts Institute of Technology, 2012)
To date, biomass has not been a large source of power generation in the United States, despite the potential for greenhouse gas (GHG) benefits from displacing coal with carbon neutral biomass. In this thesis, the fuel cycle ...
The role of hydroelectric generation in electric power systems with large scale wind generation
(Massachusetts Institute of Technology, 2012)
An increasing awareness of the operational challenges created by intermittent generation of electricity from policy-mandated renewable resources, such as wind and solar, has led to increased scrutiny of the public policies ...
