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 signify the military value of tactical data. In this project, InfoBeyond advocates EStreaming (Embedding & Streaming) for scalable and efficient graph streaming. EStreaming promotes b ...

Traditional manufacturing methods for producing warheads, propellants, and pyrotechnic systems are timely and costly. Additive manufacturing (AM) approaches offer one path of alternative manufacturing technologies. Among various technologies, powder bed fusion (PBF) is one promising approach. Hewlett Packards Multi-Jet Fusion printers utilize a unique PBF process that presents a desirable solution ...

A need exists to improve the ballistic response of armor for Littoral Combat Ships. Simply increasing armor thickness is unacceptable because the associated increase in weight and space would reduce vessel performance speed and range. Surface treatment techniques for current armor materials such as steel, aluminum and ceramic may improve armor performance significantly without an associated weight ...

Eagle Harbor Technologies, Inc. (EHT) is collaborating with researchers at the Pulsed Power and Power Electronics Center at Texas Tech University (TTU) to develop a high-power microwave switch that is capable of very fast rise times, adjustable pulse width, and high pulse repetition frequency (PRF). EHT has developed solid-state pulsed power systems that has the potential to improve the performanc ...

In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

As submarine threats from adversary countries continue to rise, the U.S. Navy must maintain and expand its anti-submarine warfare (ASW) capabilities. Warfighter readiness is the linchpin of the Navys ASW strategy, but the complexity of the ASW domain necessitates time-consuming training, and practical experiences to transfer those skills to the operational environment. An innovative training appro ...

In this Phase II STTR effort, nGimat will partner with the University of Kentucky (UK) and 3M/Ceradyne to continue development of W-scandate cathode composite materials. Compared to conventional M-type cathodes, these composite scandate nanomaterials will enable longer cathode lifetime by lowering the required operating temperature. nGimat is an established and successful powder manufacturing comp ...

Traditional weapon systems often fail to meet the requirements of close combat typical of the previously discussed engagement, where insurgents often blend in or store weapon amongst friendly or non-combatant forces, to shield them from precision strike munitions of a technologically superior force. This type of warfare has led to an increased focus on the use of less-lethal weapons, to reduce let ...

A very fast 1xN optical switch capable of handling high-optical power is proposed. It is designed for switching laser power from a central source to multiple outputs using photonic switch technology that does not have any mechanical moving parts. It is designed to have a very compact size and high-reliability operation suitable for airborne environment. The switching speed will be >10 W of optical ...

Navy operational needs dictate that thermal interface materials (TIMs) have high thermal conductance, high dielectric strength, form non-permanent bonds, and be resilient to vibration and abrasion. Available TIMs each satisfy a portion of these requirements, but not all of them.Glacigen Materials will develop a new class of TIM by creating a novel composite material. This material will be embodied ...
