Developing an accelerated aging system for gasoline particulate filters and an evaluation test for effects on engine performance
(Massachusetts Institute of Technology, 2014)
Stringent regulations worldwide will limit the level of particulate matter (PM) emitted from gasoline engines equipped with direct fuel injection. Gasoline particulate filters (GPFs) present one strategy for meeting PM ...
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 ...
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 ...
Electric ship digital twin : framework for cyber-physical system security
(Massachusetts Institute of Technology, 2019)
This thesis presents a dynamic model that can be used for a digital twin of an electric ship. The model is an end-to-end simulation of a ship from prime mover to maneuvering, seakeeping, and propeller ventilation in random ...
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 ...
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 ...
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 ...
Electronics first : development of a basic electronics course of study for naval engineers
(Massachusetts Institute of Technology, 2020)
MIT's 2N program produces naval engineers for the U.S. Navy. It provides its students with a solid foundation of critical engineering, design, construction, and naval architecture concepts. However, within that curriculum, ...
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. ...
Shipboard fault detection, load transient exploration, and power simulation
(Massachusetts Institute of Technology, 2020)
Non-intrusive load monitoring experiments have provided useful information in practice for activity tracking, condition-based maintenance, energy scorekeeping, and fault detection through various installations over several ...
