VISIMO’s ML Toolkit for Grey Literature Screening will reduce bias in, and improve accuracy of, systematic reviews (SRs) for chemical risk assessment. Grey literature is notoriously difficult to screen and tag, and despite its importance, researchers often exclude grey literature from their SRs due to necessity. VISIMO’s Toolkit will enable researchers to filter full documents of all types and ...

Ingestion of silicate particles into aircraft gas turbine (GT) engines remains a serious hazard to both commercial and military aircraft. Helicopters and low-flying fixed-wing aircraft in desert environments are exposed to airborne sand particulate. Both commercial and military aircraft can be exposed to runway dust as well as high-altitude volcanic ash. These silicate particulates present a hazar ...

In response to Navy STTR topic N23A-T010, Interphase Materials (IPM) in collaboration with the Virginia Tech Applied Research Corporation, propose the development of INTELLIPHASE, a sensor fusion and data analysis and software package, for the monitoring and prediction of the antifouling lifespan of TBTO in sonar radar domes. Sonar domes are necessary for optimal sonar performance, but require Tri ...

Textured piezoceramics is now of increasing interest to the underwater acoustic community due to their performance and/or cost benefits compared to conventional PZT and single crystals. Recent work at QorTek has shown the technology to increase source level and provide larger bandwidth relative to Type III PZT ceramics for specific designs. This enables form factor reductions and/or improved perfo ...

This program will address antenna design characteristics which can reduce the size of HF antennas for the small maritime craft while providing increased instantaneous bandwidth to provide higher data rates with higher reliability. We will apply our extensive HF experience in wideband HF ground/airborne antenna development coupled with previous efforts in conformal antennas on unique platforms to a ...

The Navy is seeking to leverage the advances in acoustic metamaterials to reduce the power consumption and cost of electronic components in hydrophone systems. There are significant challenges involved in improving the signal-to-noise ratio (SNR) and post-processing requirements, with a goal of a 10 times improvement in SNR and a 1000 times reduction in post-reception and post-detection informatio ...

Navy vessels rely on proper functioning of their Hull, Mechanical, and Electrical (HM&E) systems to perform their missions. However, faults and errors can occur unexpectedly, causing downtime and potentially hazardous situations. To address this issue, TDI Novus proposes PROPEL to detect, analyze, and classify faults and errors in real-time using probabilistic fault models trained on historical se ...

The Department of the Navy (DON) has issued a broad agency announcement as part of the Small Business Innovative Research (SBIR) program soliciting proposals for the development of a protective cover for the AN/SPY-1 radar array that will extend the service life of the coating material protecting the front face of the array, which is an Room Temperature Vulcanizing (RTV) silicone which approximate ...

As anti-submarine warfare (ASW) technologies expanded rapidly during the Cold War, towed array systems such as Surveillance Towed Array Sonar System (SURTASS) were deployed with outstanding success at detecting submarines. Later TB-29(A) and TB-34 along with the Multi-Function Towed Array (MFTA) have further increased detection capabilities. This proposal aims to develop an OAT first level multipl ...

The critical role Unmanned Underwater Vehicles (UUV) play in Naval operations is constrained by their ability to send large volumes of sensor data to warfighters. Thus, compression technology which retains all features of the data needed for human analysis, called perceptually lossless compression, is required. Additionally, our Autoencoder Compression Enhancement for UUV Sensor Data (ACE4USD) sys ...
