Separate effects of surface roughness, wettability and porosity on boiling heat transfer and critical heat flux and optimization of boiling surfaces
(Massachusetts Institute of Technology, 2012)
The separate effects of surface wettability, porosity, and roughness on critical heat flux (CHF) and heat transfer coefficient (HTC) were examined using carefully-engineered surfaces. All test surfaces were prepared on ...
Integrating response surface methods and uncertainty analysis into ship concept exploration
(Massachusetts Institute of Technology, 2002)
Accuracy control risk management for modular submarine hull construction
(Massachusetts Institute of Technology, 1999)
Shipboard condition based maintenance and integrated power system initiatives
(Massachusetts Institute of Technology, 2011)
With the U.S. Navy's continued focus on developing and implementing a robust integrated power system aboard future combatants, there has been an ever increasing effort to guarantee an electrical distribution system that ...
Experimental investigation of tearing fracture in sheets under quasi-static loading
(Massachusetts Institute of Technology, 2004)
Although there has been interest in the behavior of metal plates under blast and projectile loading for many years, definitive open-source analysis has only been recently forthcoming. This analysis is most often in the ...
Experimental study on the effect of misfit and mismatch of ship plating welds
(Massachusetts Institute of Technology, 2002)
Bragg reflector geometries for colorimetric orientation and deformation sensing
(Massachusetts Institute of Technology, 2016)
Propulsion systems of commercial and naval ships are typically large and expensive. They must be kept well-aligned and free of corrosion to efficiently and reliably transfer torque to a ship's propeller. Early identification ...
Object localization and identification for autonomous operation of surface marine vehicles
(Massachusetts Institute of Technology, 2016)
A method for autonomous navigation of surface marine vehicles is developed A camera video stream is utilized as input to achieve object localization and identification by application of state-of-the-art Machine Learning ...
Time-optimal multi-waypoint mission planning in dynamic flow fields
(Massachusetts Institute of Technology, 2018)
This thesis demonstrates the use of exact equations to predict time-optimal mission plans for a marine vehicle that visits a number of locations in a given dynamic ocean current field. The missions demonstrated begin and ...
An early conceptual design and feasibility analysis of a nuclear-powered cargo vessel
(Massachusetts Institute of Technology, 2009)
Economic globalization has resulted in the tremendous growth of worldwide trade. Much of this trade is carried out via the various waterways of the world. The bulk of these trade goods are transported by merchant ships ...
