TECHNICAL ABSTRACT: Buoyancy driven oceanographic gliders, although reasonably cost effective, have challenges operating in the zones due to high gradients in water density. Under this topic, Riptide will provide a cost-effective autonomous undersea vehicle (AUV) design leveraged from Riptide's family of man-portable AUVs that can more effectively map the hypoxic areas. The stated goals of this to ...

TECHNICAL ABSTRACT: We propose to develop and commercialize the next generation of low cost, low power, ruggedized, and accurate phytoplankton single cell and whole colony counting, characterization and classification system called HABStats. We will accomplish this using the following three unique and innovative approaches: 1) High-throughput color, Light Field Imaging Flow Cytometry to acquire mo ...

TECHNICAL ABSTRACT: Triton Systems, Inc. proposes development of the Open-Source Oceanographic Asset Recovery Beacon (OpenORB) that will allow the deployment of coastal instrumentation moorings with affordable protection against loss. This open-source kit would significantly reduce the purchase price of a commercial location beacon by allowing the end-user to assemble a customized system with mini ...

TECHNICAL ABSTRACT: Poor air quality represents a major public health risk, contributing to an estimated one of every eight deaths worldwide. Low-cost air quality sensors have developed rapidly over the last few years and offer the opportunity to make air quality monitoring inexpensive and widespread. However, low-cost sensors are currently unable to deliver accurate, reliable data due to a lack o ...

TECHNICAL ABSTRACT: Recent advances in gas chromatographic (GC) and mass spectrometric (MS) techniques for atmospheric measurements have led to highly complex data sets that have overwhelmed the capabilities of current data analysis software. We propose a new method for the automated reduction of chromatographic data using peak-fitting algorithms. By relying upon constrained peak-fit parameterizat ...

TECHNICAL ABSTRACT: We propose to continue the development of a generalized 3DVAR data assimilation module, in an open-source and non-proprietary programming language, which is compatible with FVCOM and incorporated into the Lake Erie Operational Forecast System (LEOFS). We will leverage our experience and expertise in using 3DVAR for a ROMS-based real-time forecast system for the California coast ...

TECHNICAL ABSTRACT: Tropospheric oxidation capacity is dominated by HOx photochemistry, however halogen atoms and oxides significantly affect these chemical cycles. A sensitive and robust measurement of gaseous HCl is critically important to improve our understanding of halogen chemistry and its impacts on the spatial and temporal oxidation capacity of the atmosphere. In Phase I, we met all of our ...

Threaded fastening systems in vibrating environments require a secondary locking feature, augmenting primary locking provided by an applied preload, to prevent vibration-induced loosening. The secondary locking feature can be mechanical, prevailing torque-type, or an adhesive. Self-locking nutplates and inserts are often more expensive than adhesives, require retorquing or on-torque adjustments, a ...

Over many data collection campaigns, a large number of propulsion related signature events have been observed across an extended range of the electromagnetic spectrum. The current suite of plume modeling tools contains the basic framework for flowfield and signature generation, but lacks the underlying physical mechanisms and supporting property databases to properly account for alternate waveband ...

Physical Sciences Inc. has successfully demonstrated the operational capability of a filament wound composite case designed to mitigate against slow cook-off, fast cook-off, bullet and fragment impact threats for solid rocket motor (SRM) systems. The implemented manufacturing, quality control and assurance processes enable production of small and large diameter motors to satisfy strategic and tact ...
