    • Design of the All-Electric Ship: Focus on Integrated Power System Coupled to Hydrodynamics 

      Prempraneerach, P.; Kirtley, James L., Jr.; Chryssostomidis, Chryssostomos; Triantafyllou, Michael S.; Karniadakis, George E. (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 ...
    • Development and application of distributed MEMS pressure sensor array for AUV object avoidance 

      Fernandez, Vicente Ignacio; Hou, Stephen M.; Hover, Franz S.; Lang, Jeffrey H.; Triantafyllou, Michael S. (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 ...
    • Gradient-Free Stochastic Sensitivity Analysis of the Shipboard Power System 

      Prempraneerach, P.; Foo, J.; Triantafyllou, Michael S.; Chryssostomidis, Chryssostomos; Karniadakis, George E. (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 ...
    • Lateral-Line Inspired MEMS-Array Pressure Sensing for Passive Underwater Navigation 

      Fernandez, Vicente Ignacio; Hou, Stephen M.; Hover, Franz S.; Lang, Jeffrey H.; Triantafyllou, Michael S. (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. ...
    • Science and Technology Challenges and Potential Game-changing Opportunities 

      Triantafyllou, Michael S. (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 ...
    • Touch-at-a-Distance: Pressure Microsensor Arrays for AUV Navigation 

      Lang, Jeffrey H.; Hover, Franz S.; Triantafyllou, Michael S. (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 ...
    • Towards amphibious robots: Asymmetric flapping foil motion underwater produces large thrust efficiently 

      Licht, Stephen Carl; Wibawa, Martin; Hover, Franz S.; Triantafyllou, Michael S. (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 ...
