The key to enabling successful Naval aviation operations is safe, trained, and ready personnel. Current approaches to improving aviator performance, safety, and effectiveness have critical limitations. First, the Navy does not fully leverage the wealth of data collected and maintained in operational and training settings to make improvements. In part, this is because harnessing the data to gain kn ...

Users of additive manufacturing machines expect the highest quality when it comes to the mechanical properties of parts, the usability of the machines and associated processes, and overall machine design. The main contributor to the quality of the part is the involvement of process-related by-products originating from the melting process. To handle these by-products in additive manufacturing - in ...

Current Superconducting Quantum Interference Device (SQUID) technology is capable of quantum computing, however, its application is limited due to its large size, low-temperature refrigeration requirement, and high cost.  Quantum optical semiconductor-scale chip technology is promising but not commercially available yet due to the multiple challenges to overcome. Using quantum photonic technology ...

We propose a serially concatenated switchable asymmetric Mach Zehnder switching network on a silicon nitride photonic integrated circuit platform to provide flexible and switchable demodulation of signals from less than 1 GHz to greater than 45 GHz. The silicon nitride platform provides a low size weight and power solution while reducing the stabilization requirements and providing long path lengt ...

Hepburn and Sons LLC teamed with North Carolina State University (NCSU) proposes an analysis of alternatives (AoA) to design and optimize a megawatt class, solid state transformer rectifier (SSTR) supporting maintainability of U.S. Navy shipboard power infrastructure. The design will convert 13.8kV AC to +-850V DC with modular, line-replaceable units (LRUs) that are compact and lightweight such th ...

Hepburn and Sons LLC proposes to design a ground fault detection system for 440VAC three phase radial Navy shipboard power distribution, while teaming with their partner Florida State University, Center for Advanced Power Systems (FSU CAPS). Existing Navy ground fault detection systems can detect and locate single line to ground faults on a given phase, but a second ground fault on a separate phas ...

This STTR Phase II project proposes development of a statistical relational learning framework for identification of the function of laboratory equipment from imagery. The proposed framework uses semantic reasoning to incorporate evidence from multiple classifiers and feature extractors, domain knowledge, and scene context for scene understanding and labeling. The Phase II effort will focus on dev ...

The physics generating timing spurs in a high-speed, low-bit depth analog-to-digital converter will be modeled in a machine learning framework to enable both the prediction of spurs and adaptive removal using a linearization neural network.  High-speed implementation of the spur estimation and removal networks will be accomplished.

The scope of the Phase II efforts is to develop and demonstrate the underlying software technology and use case implementation process for a common Modeling Environment for Data-Driven Diagnostics and Prognostics Development. The work performed under this effort will advance the electronics prognostics and health management (PHM) toolset and development framework defined under the Phase I research ...

Additive manufacturing (AM) technology offers the capability to use multiple glass materials and to print complex freeform shape designs and gradient index (GRIN) optics.  Although AM is widely used to print commercial 3-dimension metal and plastic/polymer parts, there are no viable commercial solutions for AM of inorganic transparent glasses for high-quality optical components. The proposed Phas ...
