The Education DesignShop : broadening non-designers' solutions for big issues
(Massachusetts Institute of Technology, 2015)
Education in America can benefit from innovation. Creating problem-solving and inventive, innovative thinking from a diverse array of people and experiences can help redefine and reinvent this important public mission. ...
Applying set based methodology in submarine concept design
(Massachusetts Institute of Technology, 2010)
Early stage ship design decisions continue to be a challenge for naval architects and engineers. The complex interactions between the different elements of the ship and the broad spectrum of disciplines required in ship ...
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 ...
Multi-criteria lifecycle evaluation of transportation fuels derived from biomass gasification
(Massachusetts Institute of Technology, 2010)
The development of a domestic biofuel industry has been a major policy thrust of the United States federal government in the first decade of the 21st century. Cellulosic biofuels have been identified as the primary candidate ...
Using polymer electrolyte membrane fuel cells in a hybrid surface ship propulsion plant to increase fuel efficiency
(Massachusetts Institute of Technology, 2010)
An increasingly mobile US Navy surface fleet and oil price uncertainty contrast with the Navy's desire to lower the amount of money spent purchasing fuel. Operational restrictions limiting fuel use are temporary and cannot ...
Naval ship propulsion and electric power systems selection for optimal fuel consumption
(Massachusetts Institute of Technology, 2011)
Although propulsion and electric power systems selection is an important part of naval ship design, respective decisions often have to be made without detailed ship knowledge (resistance, propulsors, etc.). Propulsion and ...
Comprehensive performance metrics for Complex Fenestration Systems using a relative approach
(Massachusetts Institute of Technology, 2012)
Buildings account for over 40% of the energy consumption in the United States, nearly 40% of which is attributed to lighting. The selection of a fenestration system for a building is a critical decision as it offsets ...
Model testing and computational analysis of a high speed planing hull with cambered planing surface and surface piercing hydrofoils
(Massachusetts Institute of Technology, 2015)
As part of a 2014 thesis, the MIT Innovative Ship Laboratory (iShip) designed a high-speed planing hull form that was based on the Model Variant 5631 developed at the US Navy's David Taylor Model Basin [7] [3] [5]. This ...
Naval applications of enhanced temperature, vibration and power monitoring
(Massachusetts Institute of Technology, 2015)
Navy ships require reliable information regarding their power and mechanical systems in order to perform their mission effectively. While today's shipboard systems are quite sophisticated, there are areas for improvement ...
Flexibility in early stage design of US Navy ships : an analysis of options
(Massachusetts Institute of Technology, 2011)
This thesis explores design options for naval vessels and provides a framework for analyzing their benefit to the Navy. Future demands on Navy warships, such as new or changing missions and capabilities, are unknowns at ...
