Cost prediction via quantitative analysis of complexity in U.S. Navy shipbuilding
(Massachusetts Institute of Technology, 2014)
As the sophistication and technology of ships increases, U.S. Navy shipbuilding must be an effective and cost-efficient acquirer of technology-dense one-of-a-kind ships all while meeting significant cost and schedule ...
Absolute localization of mobile robots in forest environments by correlating ground LiDAR to overhead imagery
(Massachusetts Institute of Technology, 2014)
A method for the autonomous geolocation of ground vehicles in forest environments is presented. The method provides an estimate of the global horizontal position of a vehicle strictly based on finding a geometric match ...
Creating a shipboard power simulation tool using electrical load behavior modeling
(Massachusetts Institute of Technology, 2020)
Trends in power system simulation that demand computationally-intensive, physics-based models may impede the acquisition of useful results for applications like condition-based maintenance [1], electrical plant load analysis ...
Quantification of extreme event statistics in ship design
(Massachusetts Institute of Technology, 2019)
Increased operational demands on Navy vessels extend time at sea and service life, making the accurate prediction of catastrophic failures increasingly challenging. The high value of these capital assets puts great pressure ...
Automated classification of power signals
(Massachusetts Institute of Technology, 2008)
The Non-Intrusive Load Monitor (NILM) is a device that utilizes voltage and current measurements to monitor an entire system from a single reference point. The NILM and associated software convert the V/I signal to spectral ...
Improving shipboard applications of non-intrusive load monitoring
(Massachusetts Institute of Technology, 2008)
The Non-Intrusive Load Monitor (NILM) measures equipment performance by measuring and analyzing the source power to the equipment at a single point in the electrical system. Previous studies have proven the usefulness of ...
Integrated design of semi-displacement patrol crafts
(Massachusetts Institute of Technology, 2008)
Early stage ship design and assessment continues to be a challenge for naval architects and ocean engineers. The complex and multifaceted interactions between the different components of the ship and the broad spectrum of ...
Improving the parametric method of cost estimating relationships of naval ships
(Massachusetts Institute of Technology, 2014)
In light of recent military budget cuts, there has been a recent focus on determining methods to reduce the cost of Navy ships. A RAND National Defense Research Institute study showed many sources of cost escalation for ...
Challenges facing agriculture : evaluation of the impact of AgTech, recommendations, and opportunity identification in food waste reduction
(Massachusetts Institute of Technology, 2019)
Global food production faces severe challenges that will test the world's ability to mobilize technology, industry participants, and governments to develop a sustainable response. Feeding a growing population and accommodating ...
Beamforming performance enhancement by adaptive hyperbola array shape estimation
(Massachusetts Institute of Technology, 2020)
Analysis of U.S. Navy Ice Exercise 2016 (ICEX16) data, through a collaboration with MIT Lincoln Laboratory, demonstrated that towed array curvature commonly exhibited heading differences up to 100° and never maintained ...
