Historically, the monitoring and detection of biological threats has been carried out via the deployment of high sensitivity / high complexity monitoring nodes to insure high probability of detection and low false alarm rate. Unfortunately, this detection strategy has inherent limits with respect to coverage and response due to its high deployment/support costs, mandating a new approach to environ ...

Inspecting for and detecting counterfeit, unapproved material substitutions or substandard processed raw material using existing processes is difficult, time consuming and expensive.Ocean Bay, LLC and the Primary Investigator, Karen Bruer, formed a team consisting of Ocean Bay, LLC, Savanah River National Laboratory and Old Dominion University, to apply for DLA15C-001:Detecting Substandard, Noncon ...

Adaptive Optics allow ground-based astronomical observatories to overcome atmospheric distortion limited observation by using natural and artificial guide stars to measure the distortion. Sodium-layer guide stars provide near all-sky coverage for high resolution astronomy. Over the last 20 years, Optically Pumped Semiconductor Laser (OPSL), also referred to as Vertically Extended Cavity Surface ...

The proposed project will develop advanced modeling capabilities for high-fidelity liquid-fuel spray calculations. State-of-the-art multiphase combustion models will be implemented in a volume-filtered Eulerian-Lagrangian framework that can easily be ported into existing CFD codes. Unlike traditional methods, the proposed strategy will ensure convergence under mesh refinement of the interphase exc ...

We propose development of an improved bottom database suitable for use in the frequency range of 1-10 kHz. Measured transmission loss (TL) and reverberation level (RL) will be jointly processed in building the database. The influence of the rough sea surface, rough seafloor, as well as subbottom heterogeneity will be accounted for during database generation. The rough sea surface will be character ...

Near-Field Scanning Microwave Microscopy (SMM) is a technique relying on a raster scan of a microwave probe across a sample surface, while measuring its reflected microwave signal. The existing technologies are limited to the surface analysis, and are not compatible with liquid environment. These limitations are addressed by the proposed wideband 3D tomography SMM with sub-surface analysis capabil ...

Waste generation at forward bases creates significant challenges; its disposal presents an economic cost with no direct benefit and its accumulation or burning is a health hazard. The bioconversion of waste into useful compounds could save thousands annually for every soldier and tens of millions in capital expenditure. However, widespread adoption is impeded by low conversion efficiency. We propo ...

Achieving strong and durable polymer adhesion to inorganic substrates under various environmental conditions is challenging. The required long-term durability tests are over long time- and length-scales, beyond the capability of current modeling, and extensive experimental testing is needed. Currently, no commercially available method exists for monitoring how a polymer/substrate system evolves du ...

Many environmental factors can potentially affect a communitys security. In this project, we propose to develop an open source system, called RiskWatch, for harvesting data from multiple sources and linking that data to security outcomes. Relevant data can potentially be found in a wide variety of sources, including structured, numeric data sets and images published by governments and NGOs, in na ...

There is a lack of quantitative tools to accurately map tissue viability in a rapid and quantitative manner so a surgeon can properly excise tissue prior to grafting. Spatial Frequency Domain Imaging (SFDI) is an optical method that has been shown to be a reliable method for physiology assessment - particularly for burn depth. SFDI measures of tissue structure (scattering) and function (hemoglobi ...
