Design space exploration and optimization using modern ship design tools
(Massachusetts Institute of Technology, 2014)
Modern Naval Architects use a variety of computer design tools to explore feasible options for clean sheet ship designs. Under the Naval Sea Systems Command (NAVSEA), the Naval Surface Warfare Center, Carderock Division ...
A quantitative methodology for mapping project costs to engineering decisions in naval ship design and procurement
(Massachusetts Institute of Technology, 2010)
Alternative methods for cost estimation are important in the early conceptual stages of a design when there is not enough detail to allow for a traditional quantity takeoff estimate to be performed. Much of the budgeting ...
Hardware model of a shipboard zonal electrical distribution system (ZEDS) : alternating current/direct current (AC/DC)
(Massachusetts Institute of Technology, 2010)
A hardware model of a shipboard electrical distribution system based on aspects of the DDG 51 Flight IIA, Arleigh Burke class, 60Hz Alternating Current (AC) and the future direct current (DC), zonal electrical distribution ...
Open architecture framework for improved early stage submarine design
(Massachusetts Institute of Technology, 2010)
Could transparency between current disparate methods improve efficiency in early stage submarine design? Does the lack of transparency between current design methods hinder the effectiveness of early stage submarine design? ...
Exploring the use of Model-Based Systems Engineering (MBSE) to develop systems architectures in naval ship design
(Massachusetts Institute of Technology, 2010)
The U.S. Navy designs and operates the most technologically advanced ships in the world. These ships incorporate the latest in weapons technology, phased array antennas, composite structures, signature reduction, survivability, ...
Technological development and innovation : selected policy implications
(Massachusetts Institute of Technology, 2012)
Technological development is one of the main drivers in economic progress throughout the world and is strongly linked to the creation of new industries, jobs, and wealth. This thesis attempts to better understand how a ...
Development of a design and evaluation framework for supplier cities
(Massachusetts Institute of Technology, 2007)
For companies pursuing opportunities by expanding manufacturing to new markets, one major challenge is unavoidable: identifying and developing capable, local suppliers. In developing markets suppliers often lack the cutting ...
Heavy-duty diesel vehicle Nox̳ aftertreatment in 2010 : the infrastructure and compliance challenges of urea-SCR
(Massachusetts Institute of Technology, 2008)
Increasingly stringent heavy-duty vehicle emission regulations are prompting the use of PM and NOx aftertreatment systems in the US, the EU and Japan. In the US, the EPA Highway Diesel Rule, which will be fully implemented ...
Hydrophobicity of rare-earth oxide ceramics and their application in promoting sustained drop-wise condensation
(Massachusetts Institute of Technology, 2016)
Hydrophobic surfaces that are robust can have widespread applications in various industries including energy, hydropower, and transportation. In particular, hydrophobic materials promote dropwise condensation, which results ...
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 ...
