Advancing clinical gait analysis through technology and policy
(Massachusetts Institute of Technology, 2009)
Quantitatively analyzing human gait biomechanics will improve our ability to diagnose and treat disability and to measure the effectiveness of assistive devices. Gait analysis is one technology used to analyze walking, but ...
Modeling and control of airport departure processes for emissions reduction
(Massachusetts Institute of Technology, 2009)
Taxiing aircraft contribute significantly to the fuel burn and emissions at airports. This thesis investigates the possibility of reducing fuel burn and emissions from surface operations through a reduction of the taxi ...
A technoregulatory analysis of government regulation and oversight in the United States for the protection of passenger safety in commercial human spaceflight
(Massachusetts Institute of Technology, 2009)
Commercial human spaceflight looks ready to take off as an industry, with "space tourism" as its first application. Paying passengers are likely to begin taking suborbital spaceflights within the next several years, both ...
Metrics for enterprise transformation
(Massachusetts Institute of Technology, 2009)
The objective of this thesis is to depict the role of metrics in the evolving journey of enterprise transformation. To this end, three propositions are explored: (i) metrics and measurement systems drive transformation, ...
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 ...
Methods for managing uncertainly in material selection decisions : robustness of early stage life cycle assessment
(Massachusetts Institute of Technology, 2009)
Utilizing alternative materials is an important tactic to improve the environmental performance of products. Currently a growing array of materials candidates confronts today's product designer. While life-cycle assessment ...
Impact of European Emissions Trading System (EU-ETS) on carbon emissions and investment decisions in the power sector
(Massachusetts Institute of Technology, 2009)
This masters thesis assesses the impact of a emissions trading on short-term carbon abatement and investment decisions in the power sector. Environmental benefits from carbon abatement due to emissions trading are quantified ...
Economics of nuclear fuel cycles : option valuation and neutronics simulation of mixed oxide fuels
(Massachusetts Institute of Technology, 2009)
In most studies aiming at the economic assessment of nuclear fuel cycles, a primary concern is to keep scenarios economically comparable. For Uranium Oxide (UOX) and Mixed Oxide (MOX) fuels, a traditional way to achieve ...
What drives spacecraft innovation? : a quantitative analysis of communication satellite history
(Massachusetts Institute of Technology, 2009)
The overall goal of this research is to develop a better understanding of how innovation can, and should, happen in the space sector. Part A: Towards an Empirical Measure of Spacecraft Innovation, frames the discussion of ...
The influence of higher education on the national innovation system in Portugal
(Massachusetts Institute of Technology, 2009)
Many economists agree that countries wishing to develop their national economies should focus on increasing their innovation output. In recent years, the Portuguese government has pursued this goal, taking strides to improve ...
