TDA has teamed up with Lawrence Livermore National Laboratory as its research institution collaborator to address the target STTR topic objective of quantifying the uncertainties in the mechanical behavior of the AM parts. To quantify uncertainties by minimizing both the computational burden and expensive testing and also overcoming the IP concerns, we propose a novel approach with three layered i ...

During AM of metallic alloys, a material exhibits several complex physical phenomena that impact the spatial distribution of heterogeneous material properties within a built component. Subsequent post-processing alters the already heterogeneous location-specific material properties. This project is to develop a novel methodology for linking the time and length scales of the various physical phenom ...

During Phase I, we propose to develop nanostructured, low friction thermal sprayed coatings that are able to withstand high dynamic loadings. Additionally, the novel coatings will possess a low friction coefficients in humid air, dried conditions and various greases and lubricants. These novel nanostructured coatings will be manufactured by HVOF spraying of solid lubricants based nanostructured po ...

Oceanit proposes to develop and demonstrate novel, tailored, designer separator materials with optimized properties to maximize lithium-ion cell/battery performance, life, safety and reliability.

In this phase I we propose to extend our work on MVDC isolation device to include fault detection, and fault localization circuitry. We have previously developed under an SBIR a 6 kVDC, 2000A isolation device that was built and tested in MVDC ship distribution system laboratory at FSU CAPS. In this phase I we propose to use rogowski coils and hall effect probes to detect faults and we propose to a ...

Hepburn and Sons LLC teamed with Florida State University (FSU) Center for Advanced Power Systems (CAPS) propose to develop an affordable, general method for grounding Medium Voltage Direct Current (MVDC) zonal electrical power systems for naval warships. The grounding system concept developed in Phase I will evaluate the incorporation of electric weapons and high power sensors while accounting fo ...

Cyber security forensic functions depend on highly structured conformance to log formats for generation and transmission capabilities including identity, network time stamps and event message formats. Without this structure there is no effective way to reconstruct the time sequencing patterns that reveal the presence of unauthorized actions and actors inside of a network. Limitations in the capaci ...

Using a fluid dynamic energy separation technique, in combination with thermoelectric generators (TEGs), a unique hybrid cooling system using low grade waste heat is proposed. This system uses the concept of fluid structure interactions and vorticity redistribution to produce large levels of vorticity within working fluid and thereby generate large temperature gradients in the working fluid which ...

The marine environment is extremely corrosive to turbine engine components due to the large amount of salts from the sea coupled with the fuel impurities and the high temperatures experienced. To cope with future operational requirements, a strong need exists to develop novel, protective coatings to provide environmental protection from hot corrosion and oxidation conditions across a wide range of ...

The Navy needs to fuse and distill time-stamped data sources as varied as overhead imagery and Twitter feeds into actionable intelligence such as alerts, on-demand reports about entities of interest, and search capabilities. In order to enable such analytics, it is effective to learn fixed dimensional vectors (embeddings) representing the entities present in these heterogeneous data sources, which ...
