    • A matched field processing approach to long range acoustic navigation 

      Deffenbaugh, Max (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-02)
      This thesis presents the design and simulation of an acoustic listen-only navigation system for use in a time-varying high-multipath environment. The system uses a ray tracing model of sound propagation in a horizontally ...
    • Mating behavior, population growth, and the operational sex ratio : a periodic two‐sex model approach 

      Jenouvrier, Stephanie; Caswell, Hal; Barbraud, Christophe; Weimerskirch, Henri (University of Chicago Press, 2010-04-21)
      We present a new approach to modeling two‐sex populations, using periodic, nonlinear two‐sex matrix models. The models project the population growth rate, the population structure, and any ratio of interest (e.g., operational ...
    • Matrix models and sensitivity analysis of populations classified by age and stage : a vec-permutation matrix approach 

      Caswell, Hal (Springer, 2011-06-14)
      Matrix population models in which individuals are classified by both age and stage can be constructed using the vec-permutation matrix. The resulting age-stage models can be used to derive the age-specific consequences of ...
    • Maximizing AUV slow speed performance 

      LeBas, Phillip J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-09)
      A review of the Odyssey IIB autonomous underwater vehicle shows that energy costs associated with vehicle controls can be reduced and operational flexibility improved with relatively simple, low cost improvements. Because ...
