Disruptive Technology Associates will develop additive manufacturing (3-D printing) techniques for microwave vacuum electronics that will change the supply chain, allowing vacuum electronics units to be built with lower overall cost while supporting a sporadic ordering cycle. The Phase I program address several key material and materials integration risk areas. The program will assess several type ...

Military and civilian agencies can benefit from systems that create 4D, spatio-temporal representations of dynamic scenes for target tracking, law enforcement, crowd control, disaster recovery, etc. Proliferation of imaging sensors such as surveillance cameras, car- and body-mounted cameras, and cell phones, provides the opportunity for reconstructing a dynamic scene in a very inexpensive way. Tod ...

The objective of STTR Topic N16A-T013, Cyber Forensic Tool Kit for Machinery Control, is to develop live digital forensics that, at run time, provide a cyber-protection strategy and aid in identification of malfunctions due to malicious and non-malicious events, while ensuring minimal impact on overall system performance. A proposal has been prepared by TDI Technologies, Inc., a small business bas ...

In this STTR, Daniel H. Wagner Associates, together with the University of Michigan (UM), will develop a Detection Avoidance System for Submarines (DASS). The proposed DASS is a set of software modules which solves the probabilistic passive sonar equation (PSE) using given environmental acoustic data, assesses submarine vulnerability based on intelligence about potential threat ASW assets, recomme ...

Corrosive environments together with cyclic loading can lead to the formation of localized corrosion pits and corrosion fatigue cracks which can significantly deteriorate the structural integrity of aircraft components. The exact nature of corrosion fatigue damage is dependent on the competing multi-scale processes resulting from complex interactions between the structural material, its environmen ...

Navy needs a real-time graph embedding tool for analyzing huge graphs (millions of nodes and billions of edges) from diverse sources. However, current approaches cannot provide dynamic and scalable graph analytics to show the military value of tactical data. In this project, InfoBeyond advocates EStreaming (Embedding & Streaming) for scalable and efficient graph streaming. EStreaming promotes big ...

Foil/air bearings have the benefit of negligible friction and wear once sufficient airflow is obtained; however, during spin up and spin down these bearings are subject to contact with the rotating surfaces upon which they act and thus are subject to frictional losses and wear. Modern air-cycle machines (ACMs) depend on solid lubricant based coating materials such as polyimide coatings to protect ...

Turbulent shear flows in naval applications are characterized by vastly different lengths and time scales associated with rotor tip vortices and the vortical structures shed from the ship, and additional phase from water drops and water vapor. To tackle the modeling challenges, we propose a novel methodology that combines a vorticity preserving method and a new approach to LES turbulence modeling ...

Surgical simulations aiming to support surgeon practices and medical education have attracted enormous research effort over the last two decades. However, the physical reality, especially on simulating aggregated tissue interaction, is still unsatisfactory. In this proposed work, an open source surgery simulation framework, SoFMIS, will be utilized and enhanced with tissue interaction models to a ...

Computational Sciences LLC will collaborate with the Rensselaer Polytechnic Institute (RPI) to develop and validate a stand-alone computational module that naturally accounts for the effects of turbulence. Such fluctuations and transitions may be associated with compressible flows and boundary layer interactions. The module will be designed for implementation in to existing legacy codes for use in ...
