A tool to create hydrodynamically optimized hull-forms with geometrical constraints from internal arrangements
(Massachusetts Institute of Technology, 2013)
Internal arrangements and bulky equipment like machinery have been treated for many years as a secondary aspect of the ship design. Traditionally, in the design process, the centerpiece of the effort is the hull and its ...
Design and analysis of US Navy shipbuilding contract architecture
(Massachusetts Institute of Technology, 2015)
Contracting for US Navy ship procurement is complex due several factors such as budgetary and political concerns, sole or near sole source environments, and long lead-time construction. In the current climate of shrinking ...
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 ...
Vulnerability analysis of an all-electric warship
(Massachusetts Institute of Technology, 2010)
Traditional design processes usually rely on cost as the metric the designer uses to select among different alternatives. Sometimes when costs cannot be calculated we use weight, volume and efficiency as surrogates for ...
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 ...
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 ...
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 ...
Automation as a manpower reduction strategy in navy ships
(Massachusetts Institute of Technology, 2016)
Since the early 2000's, the US Navy has endeavored to decrease the Total Ownership Cost (TOC) of their ships through a decrease in Operating and Support costs. This led to a large-scale effort by ship program managers to ...
