Multipath arrival tracking for marine vehicles utilizing pattern recognition
(Massachusetts Institute of Technology, 2018)
In recent years, interest in the Arctic Region has been steadily growing as it has become more accessible due to continued ice recession. This increased accessibility opens up the possibility for nations to take advantage ...
Design and testing of an autonomous mothership for surface vehicle swarm docking
(Massachusetts Institute of Technology, 2019)
The field of marine autonomous systems has blossomed over the past several decades yet much remains to be explored. One important focus area gaining increased attention in this domain is the understanding and development ...
Design and construction of a propeller open water testing apparatus and testing of a stereolithography 3D printed model propeller
(Massachusetts Institute of Technology, 2019)
This thesis describes the design and construction of a propeller open water testing apparatus for educational and experimental use at MIT. This test apparatus was built as an inexpensive alternative to conducted in-house ...
Design, construction, and analysis of a modular ship model and open-source autonomous surface vehicle
(Massachusetts Institute of Technology, 2020)
Existing models used to explore hydrostatic, hydrodynamic, seakeeping, and maneuvering characteristics of ships are limited in that their characteristics are essentially static. The effects of various hull appendages, ...
The design, feasibility and cost analysis of sea barrier systems in Norfolk, Virginia and the comparative cost of shoreline barriers
(Massachusetts Institute of Technology, 2020)
Protecting a coastline from the damage of a storm surge, or tidal flooding associated with sea level rise, is a challenging and costly engineering endeavor. Low lying properties located directly on an ocean coastline are ...
Nondestructive evaluation of composite rods using ultrasonic wave propagation
(Massachusetts Institute of Technology, 2015)
Nondestructive Evaluation (NDE) is a branch of applied science that is concerned with assessing the properties and serviceability of materials and structures without causing collateral damage or depreciation. This study ...
Evaluation by simulation of an acoustic array composed of multiple autonomous vehicles
(Massachusetts Institute of Technology, 2015)
Ship-towed arrays have been integral to Navy combatant operations for many decades. The continual advancement of towed array technology has been continually driven by the need for high sensitivity, low self-noise, and ...
Hydrodynamic analysis of the offshore floating nuclear power plant
(Massachusetts Institute of Technology, 2015)
Hydrodynamic analysis of two models of the Offshore Floating Nuclear Plant [91 was conducted. The OFNP-300 and the OFNP-1100 were both exposed to computer simulated sea states in the computer program OrcaFlex: first to ...
Mechanical characterization of lithium-ion battery micro components for development of homogenized and multilayer material models
(Massachusetts Institute of Technology, 2014)
The overall battery research of the Impact and Crashworthiness Laboratory (ICL) at MIT has been focused on understanding the battery's mechanical properties so that individual battery cells and battery packs can be ...
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 ...
