Human interaction in cyberspace leaves indicators in the three layers that define cyberspace: persona, logical and physical. The proposed effort seeks to develop algorithms and software to integrate data and context across all three layers, “intertwining” data to create a more holistic and complete picture of cyber activity. Such an integrated perspective will allow cyber professionals to bett ...

Active imaging systems are used in degraded visual environments, like those found in marine fog and other areas with a high level of attenuation and scattering from obscurants like rain, smoke and dust. These systems are still limited in range and resolution. SA Photonics is taking advantage of new eyesafe, hybrid fiber-bulk laser technology capable of high pulse energy at high repetition rate to ...

The objective of this project is to develop a compact and efficient avalanche photodiode (APD), operating between 210-260 nm, for implementation in the next generation bio-chem-detectors. The proposed detectors will be based on the AlGaN materials system and will be solar blind, highly sensitive, smaller, less expensive, and more robust than current UV detectors. Development of such APDs will enab ...

Treatment of water with ultraviolet (UV) light, which destroys target DNA of microorganisms, is the safest, most reliable, and sustainable way of freeing water from microbial contamination. This process is desired in place of chlorination and is widely used in the US for wastewater treatment. We propose the development of a highly efficient UV LED with emission at 265 nm, with EQE>30%, and WPE>15% ...

The United States Air Force (USAF) has a long history of using human performance models to increase the effectiveness of training, and predict the impact of physical factors (like fatigue) and environmental factors (like time pressures and information uncertainty). Within Phase I, Sonalysts and Miami University worked to improve the quality of these models through the development of the EEG Modeli ...

Current design tools for gas turbine engines invoke a variety of simplifying assumptions to estimate heat transfer to solid/metal engine components (e.g., isothermal boundary conditions). These approximations are often not valid, result in inaccurate predictions of heat transfer, and ultimately compromise the thermal integrity of propulsion and power systems. Wall-modeled large eddy simulation (WM ...

Autonomous vehicles are being used for many applications varying from small indoor robots, to large-scale mining trucks, and military vehicles operating in fast-changing environments. Global position systems (GPS) have traditionally been used for vehicle positioning. GPS works well in open environments, but suffers from significant degradation due to terrain, certain operating conditions, and even ...

We propose to investigate, in collaboration with MGH Voice Center and Altec, Inc., application of surface electromyography (sEMG) to assessing cognitive workload, strain, and overload. Specifically, sEMG sensors placed on the face and neck will detect emotional/motor responses to workload strain. The proposed effort will build on the substantial sEMG experience of our partner, MGH (including resea ...

Kyma Technologies, the leading domestic supplier of crystalline III-N substrate materials, is teamed with leading AlGaN materials & device experts at Sandia National Laboratories (SNL) to develop high-quality n-type conductive 2-inch diameter epi-ready free-standing AlGaN substrates in support of next generation AlGaN devices with applications in ultraviolet optoelectronics, power electronics, and ...

The Department of the Navy has a need for the development of an additive manufacturing (AM) process for key vacuum electronic device components to meet on-demand, flexible, and affordable manufacturing requirements. The goal of this Phase II effort is to develop and validate Electron Beam Melting (EBM) additive manufacturing (AM) technology for the production of vacuum electronic devices meeting t ...
