Science and Technology Challenges and Potential Game-changing Opportunities
(Massachusetts Institute of Technology. Sea Grant College Program, 2011)
The future of naval engineering in the 21st century will be shaped by novel and emerging technologies that will not only provide unprecedented capabilities but also require radical rethinking of naval ship and vehicle ...
Towards amphibious robots: Asymmetric flapping foil motion underwater produces large thrust efficiently
(Massachusetts Institute of Technology. Sea Grant College Program, 2009)
The development of amphibious robots requires actuation that enables them to crawl as well as swim; sea turtles are excellent examples of amphibious functionality, that can serve as the biomimetic model for the development ...
Gradient-Free Stochastic Sensitivity Analysis of the Shipboard Power System
(Massachusetts Institute of Technology. Sea Grant College Program, 2008)
Sensitivity analysis results are useful both for the early design stage – where the parametric space can be substantially reduced – but also in operating conditions, e.g. of the future electric ship, resulting in reduced ...
Development and application of distributed MEMS pressure sensor array for AUV object avoidance
(Massachusetts Institute of Technology. Sea Grant College Program, 2009-07)
A novel sensory system is being developed for AUVs to augment current sensory systems for navigation and operation in difficult environments. These environments are frequently cluttered and murky with substantial flow from ...
Touch-at-a-Distance: Pressure Microsensor Arrays for AUV Navigation
(Massachusetts Institute of Technology. Sea Grant College Program, 2009)
Inspired by the lateral-line organ in fish, the ultimate objective of this project continues to be the development of a passive system for AUVs that can detect, classify and locate underwater objects. The lateral line ...
Lateral-Line Inspired MEMS-Array Pressure Sensing for Passive Underwater Navigation
(Massachusetts Institute of Technology. Sea Grant College Program, 2007-07)
This paper presents work toward the development of a novel MEMS sensing technology for AUVs. The proposed lateral line-inspired sensor system is a high-density array of pressure sensors for measuring hydrodynamic disturbances. ...
Design of the All-Electric Ship: Focus on Integrated Power System Coupled to Hydrodynamics
(Massachusetts Institute of Technology. Sea Grant College Program, 2008)
We present a detailed model of the integrated power system coupled to hydrodynamics that allows us to study global sensitivities in the All-Electric Ship. A novel element of our formulation is the stochastic modeling of ...
