 | This thesis examines the possibility of integrating an acoustic modem onto a Wave Glider with the goal of providing a bidirectional communications gateway for submerged sensors, platforms, and networks. The Wave Glider unmanned surface vehicle continuously harvests energy from the environment and is able to hold station without needing to refuel. A unique two-body architecture and wing system directly converts wave motion into thrust, and solar panels provide electricity for ... |

| The Joint Primary Aircraft Training System (JPATS) lost the supplier for its canopy fracturing initiation system (CFIS) with no prospect for a replacement. This forced a complete CFIS redesign to supply both an active production line and sustain fielded aircraft. Compounding the problem, the existing CFIS became obsolete, which forced an interim design to be produced until a final long term solution was fielded. This thesis developed a method to ... |

| Lateral mixing is driven through the interplay between finescale isopycnal stirring (shear + strain) and small-scale diapycnal turbulence. We seek to understand this interplay within highly anisotropic coherent structures, such as fronts, jets, eddies and filaments, which likely control lateral dispersion in both coastal and open ocean. These structures evolve yet are often persistent on O (3 day) timescales, so are ideally suited to be adaptively sampled by autonomous gliders ... |

| Authors:
N Slegers; O A Yakimenko; NAVAL POSTGRADUATE SCHOOL MONTEREY CA DEPT OF MECHANICAL AND ASTRONAUTICAL ENGINEERING
|
| Autonomous precision placement of parafoils is challenging because of their limited control authority and sensitivity to winds. In particular, when wind speed is near the airspeed guidance is further complicated by the parafoils inability to penetrate the wind. This article specifically addresses the terminal phase and develops an approach for generating optimal trajectories in real-time based on the inverse dynamics in the virtual domain. The method results in efficient solution ... |

| Characterizing in situ water turbidity is critical to numerous naval operations. In particular, water column turbidity impacts the efficacy of sensors that use optical measurements for a variety of purposes including laser detection of mines and prediction of the operational detection horizon for bioluminescence and diver visibility algorithms. Nepheloid layers, are optically significant and represent a nearly universal turbid feature in the coastal ocean. The maintenance of these nepheloid layers ... |

| The goal of this multi-phased effort is to provide over-the-horizon characterization of the ocean water column and seafloor so that areas of safe operations can be identified and sonar performance can be accurately predicted. The tasks to accomplish this are: (1) use autonomous vehicles carrying wideband sensors to improve environmental measurement capabilities, (2) modify geoacoustic inversion algorithms to reduce solution ambiguity, (3) assess and characterize environmental geoacoustic variability and its ... |
