Systems that operate in constrained environments depend on the acoustics in several ways. Harbor defense systems detect intruders (people and/or vessels) by either listening for their noises (passively) or by pinging on them and detecting their echoes (actively). Furthermore, such systems may also form the equivalent of an underwater cell phone network using sound to carry the information. The aco ...

The ubiquity of high-resolution imagery and video taken by surveillance cameras, handheld cameras, vehicle-mounted cameras, and airborne cameras is creating a rich source of dynamic data that offers opportunities for effectively solving defense, security and law enforcement problems. But in order to develop effective scene and activity understanding applications we must develop robust, accurate an ...

This effort is focused on establishing an important capability of providing a comprehensive, advanced model of the three-dimensional acoustic field, including propagation, scattering, and reverberation in complex and dynamic environments. This new 3D acoustic model would feed the Navys sonar performance estimation tool with a purpose of addressing the optimal placement of sensors in complicated en ...

SA Photonics is pleased to propose the SOCRATES free space optical communication and sensing system featuring the Photonic Optical Multicast Mast Unit (POMMU). SOCRATES enables 360 degree multicast capability of high bandwidth communication in addition threat search and track capability. SA Photonics will team with the Prof. Michal Lipson of the Lipson Nanophotonics Group at Columbia University wh ...

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 ...

A particularly challenging task for the US Navy today is that of Explosive Ordnance Disposal (EOD) of underwater mines; the Mine Countermeasures (MCM) mission. The semi-submersible Remote Multi-Mission Vehicle (RMMV) has emerged as an unmanned solution to handle MCM missions. While the RMMV is groundbreaking, the basis of the technology is a relatively slow-moving watercraft.GreenSight Agronomics, ...

DeepDive is a system for extracting relational databases from dark data: the mass of text, tables, and images that are widely collected and stored but which cannot be exploited by standard relational tools. If the information in dark data --- scientific papers, Web classified ads, customer service notes, and so on --- were instead in a relational database, it would give analysts access to a massiv ...

This Navy STTR Phase I proposal presents an unprecedented NDI tool to quantify mechanical properties of metal parts made with laser additive manufacturing with material characteristics and process parameters. A fiber laser SAW and heterodyne detection is used with LIBS to study both in-process and post-process for both flat and shaped parts. It is the enabling technology for characterize the AM pa ...

The goal of the proposed research is to develop light-weight, flexible, high efficiency solar cells made from perovskite halide light-harvesting materials for use on unmanned aircraft systems (UAS), for use in conjunction with an energy storage system. Solar cells have historically been heavy, costly, and inflexible. In this research, low-cost manufacturing methods will be used to make high effici ...

The purpose of this project is to demonstrate the feasibility of using an innovative, durable, low friction, and non-toxic solid lubricant coating for foil air bearings for air cycle machines (ACM). Acrees coating provides superior wear characteristics at all temperatures and provides a substantial improvement over polyimide type coatings that are currently used on ACMs. The coating consists of tw ...
