Design and analysis of mobile sensing systems : an environmental data collection swarm
(Massachusetts Institute of Technology, 2016)
Recent advances in small-scale portable computing have lead to an explosion in swarming as a viable method to approach large-scale data problems in the commercial, scientific, and defense sectors. This increased attention ...
The NILM Dashboard : watchstanding and real-time fault detection using Non-intrusive Load Monitoring
(Massachusetts Institute of Technology, 2019)
Non-intrusive Load Monitoring (NILM) measures power at a central point in an electrical network and disaggregates individual load schedules from the overall power stream. This thesis presents the NILM Dashboard, a data-analysis ...
Design of low cost biomimetic flexible robots using additive manufacturing techniques
(Massachusetts Institute of Technology, 2019)
In this thesis, I designed and fabricated robots leveraging additive manufacturing. This had two overarching purpose. One to make a testing apparatus that would allow the measurements of the influence of a flexible flapping ...
Resistance and wake prediction for early stage ship design
(Massachusetts Institute of Technology, 2013)
Before the detailed design of a new vessel a designer would like to explore the design space to identify an appropriate starting point for the concept design. The base design needs to be done at the preliminary design level ...
Modeling brake specific fuel consumption to support exploration of doubly fed electric machines in naval engineering applications
(Massachusetts Institute of Technology, 2016)
The dynamic operational nature of naval power and propulsion requires Ship Design and Program Managers to design and select prime movers using a much more complex speed profile rather than typical of commercial vessels. ...
Ocean acoustic uncertainty for submarine applications
(Massachusetts Institute of Technology, 2016)
The focus of this research is to study the uncertainties forecast by multi-resolution ocean models and quantify how those uncertainties affect the pressure fields estimated by coupled ocean models. The quantified uncertainty ...
Uranium extraction from seawater : investigating hydrodynamic behavior and performance of porous shells
(Massachusetts Institute of Technology, 2017)
As global economies grow and demand more energy, scientists work to develop alternative sources to meet demand. Developing countries, e.g. China and India in particular, will turn to nuclear power to meet their energy ...
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 ...
The Shipboard Automatic Watchstander (SAW) : utilization of Nonintrusive Load Monitoring for shipboard automation
(Massachusetts Institute of Technology, 2017)
This thesis presents results from operational testing of Nonintrusive Load Monitoring (NILM) systems aboard active US Coast Guard units. Monitoring the ships' electrical system from centralized power distribution points, ...
Hydrodynamics of high speed planing hulls with partially ventilated bottom and hydrofoils
(Massachusetts Institute of Technology, 2014)
The influence of a cambered shaped bottom step on the performance of sea going V-stepped planing hulls is investigated using numerical methods. The shape of the step was designed to decrease the Drag/Lift ratio of the hull ...
