A stochastic life cycle and greenhouse gas abatement cost assessment of renewable drop-in fuels
(Massachusetts Institute of Technology, 2020)
Assessing the technical, economic and policy-centered feasibility of a proposed satellite communication system for the developing world
(Massachusetts Institute of Technology, 2005)
Satellite communication systems remain one of the most under utilized development mediums in less industrialized countries. This research proposes to establish a low cost satellite communications system tailored specifically ...
Impact of alternative nuclear fuel cycle options on infrastructure and fuel requirements, actinide and waste inventories, and economics
(Massachusetts Institute of Technology, 2009)
The nuclear fuel once-through cycle (OTC) scheme currently practiced in the U.S. leads to accumulation of uranium, transuranic (TRU) and fission product inventories in the spent nuclear fuel. Various separation and recycling ...
A technical, financial, and policy analysis of the RAMSES RFID inventory management system for NASA's International Space Station: prospects for SBIR/STTR technology infusion
(Massachusetts Institute of Technology, 2010)
Engineering, management, and social science methodologies have been employed to analyze a new asset tracking and management system for human spaceflight applications. The Massachusetts Institute of Technology and Aurora ...
Tools of risk management in product verification
(Massachusetts Institute of Technology, 2003)
Product development and innovation involve uncertainty, which inevitably incurs risk. Especially, as product development cycles shorten and resources condense, and as the products themselves grow more complex, managing ...
The evolution of network competition in transatlantic aviation and the effects of regulatory liberalization
(Massachusetts Institute of Technology, 2009)
Since the domestic deregulation of the U.S. airline industry in 1978, impacts to domestic stakeholders, including airlines, airports, labor and consumers, have been well-studied. International air transportation, however, ...
Designing sustainable heavy lift launch vehicle architectures adaptability, lock-in, and system evolution
(Massachusetts Institute of Technology, 2005)
Long term human space exploration depends on the development of a sustainable heavy lift launch vehicle (HLLV). But what exactly is sustainability in the context of launch systems and how can it addressed in the design ...
Political sustainability in the vision for space exploration : articulating the policy-technology feedback cycle
(Massachusetts Institute of Technology, 2006)
It is often difficult to forecast the future budgetary environment for today's space systems. Indeed, multiple NASA missions and programs have been put into jeopardy or canceled outright, due to discrepancies between the ...
Astronaut Extravehicular Activity : safety, injury & countermeasures; &, Orbital collisions & space debris : incidence, impact & international policy
(Massachusetts Institute of Technology, 2010)
Extravehicular Activity (EVA) spacesuits are a key enabling technology which allow astronauts to survive and work in the harsh environment of space. Of the entire spacesuit, the gloves may perhaps be considered the most ...
