  • Eskesen, Justin; Owens, Dylan; Soroka, Michael; Morash, Jim; Hover, Franz S.; Chryssostomidis, Chryssostomos (Massachusetts Institute of Technology. Sea Grant College Program, 2009)
    The Odyssey IV class AUV was designed to fill the evolving needs of research and industry for a deep rated (6000 meter) vehicle, which is capable of both efficient cruising and precise hovering. This AUV is powerful enough ...
  • 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 ...
  • 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 ...
  • Cooke, Chathan M.; Chalfant, Julie; Chryssostomidis, Chryssostomos (Massachusetts Institute of Technology. Sea Grant College Program, 2012-12)
    In response to a Request for Information from the Office of Naval Research regarding electrical architectures to be considered in an architecture evaluation study for two candidate hull forms including a 10,000 ton ...
  • Proper, Ethan; Cox, Robert W.; Leeb, Steven B.; Douglas, Keith; Paris, Jim; Wichakool, Warit; Foulks, Edward L.; Jones, Richard; Branch, Perry; Fuller, Ashley; Leghorn, Jeremy; Elkins, Greg (Massachusetts Institute of Technology. Sea Grant College Program, 2009)
    The performance of important electrical loads on mission critical systems like warships or off-shore platforms is often tracked by dedicated monitoring equipment. Individual monitoring of each load is expensive and risky. ...
  • Dassuncao, Clifton (Massachusetts Institute of Technology. Sea Grant College Program, 2008-12)
    The globalization of consumer goods and natural resources has led to an unintentional increase in exchanges of native biota (Bright 1999, Barbier and Shogren 2004, Perrings et al. 2005). Organisms that were once constrained ...
  • 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 ...
  • Pederson, Judith (Massachusetts Institute of Technology. Sea Grant College Program, 2009-02)
    The Gulf of Maine Regional Ocean Science Initiative evolved from an awareness of the importance of integrated approaches to addressing ecological, environmental, and social influences in coastal and marine ecosystems at ...
  • Chalfant, Julie; Ferrante, Matthew D.; Noble, James A. (Massachusetts Institute of Technology. Sea Grant College Program, 2014-09)
    The Naval Surface Warfare Center Carderock Division has created the Leading Edge Architecture for Prototyping Systems, or LEAPS, as the data repository for ship design, and a significant number of the early-stage ship ...
  • 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. ...
  • Hover, Franz S. (Massachusetts Institute of Technology. Sea Grant College Program, 2007)
    We propose a simple method of control system design for marine vehicles with one or more azimuthing propulsors, and specifically for the case where the speed of the actuator is on the same time scale as the plant dynamic ...
  • Pappal, Adrienne; Smith, Jan; Pederson, Judith (Massachusetts Institute of Technology. Sea Grant College Program, 2010)
    Non-native species have emerged as one of the leading environmental threats to our coastal habitats. These species have been recognized globally as a major threat to biological diversity as well as to agriculture and other ...
  • Pederson, Judith; Bullock, Robert; Carlton, James; Dijkstra, Jennifer; Dobroski, Nicole; Dyrynda, Peter; Fisher, Ryan; Harris, Larry; Hobbs, Niels; Lambert, Gretchen; Lazo-Wasem, Eric; Mathieson, Arthur; Miglietta, Maria-Pia; Smith, Jan; Smith III, Julian; Tyrrell, Megan (Massachusetts Institute of Technology. Sea Grant College Program, 2005)
    In his seminal book on The Ecology of Invasions by Animals and Plants, Elton (1958) laid the foundation for the science of biological invasions. He identified the importance of human-mediated vectors as means of transporting ...
  • Benjamin, Michael Richard (Massachusetts Institute of Technology. Sea Grant College Program, 2011-07)
    This document describes 19 MOOS-IvP autonomy tools. uHelmScope provides a run-time scoping window into the state of an active IvP Helm executing its mission. pMarineViewer is a geo-based GUI tool for rendering marine ...
  • Misic, Aleksandar (Massachusetts Institute of Technology. Sea Grant College Program, 2014-09)
    The goal of this project is to efficiently and safely charge a 5kWh battery pack in 15 minutes. Since the project is still in progress, this report describes experiments on a 56Wh battery. Experiments were performed to ...
  • Benjamin, Michael Richard; Schmidt, Henrik; Newman, Paul; Leonard, John Joseph (Massachusetts Institute of Technology. Sea Grant College Program, 2011-08)
    This document describes the IvP Helm - an Open Source behavior-based autonomy application for unmanned vehicles. IvP is short for interval programming - a technique for representing and solving multi-objective optimizations ...
  • Babaee, Hessam (Massachusetts Institute of Technology. Sea Grant College Program, 2014)
    We formulated an S-curve parameterization for re-routing a cable path for a given offset displacement. In our approach we assume the cable path to follow a tangent hyperbolic curve. In our formulation, after taking the ...
  • Bailey, Gregory; Baril, Jacob A.; Bellini, Jonas A. (Massachusetts Institute of Technology. Sea Grant College Program, 2012-03)
    This project investigated whether hazard mitigation plans (HMPs) and comprehensive water resource management plans (CWRMPs) completed by cities and towns in Massachusetts account for the long term effects of climate change. ...
