ABSTRACT: Protection of first responders who are exposed to hazards including chemical warfare agents (CWAs) is a very critical need. The need is derived from not only their welfare but their ability to respond, protect the community and provide logistical support to the response. A simple exposure monitor would provide critical information to the first responder and allow them to respond accor ...

Additive Manufacturing (AM), where three-dimensional (3D) objects are created from a digital model by depositing and fusing successive layers of material, provides the ability to produce low-volume, customized products with complex geometries relatively quickly at a moderate cost. However, AM processes sometimes fail to produce acceptable parts, due to either geometric in- accuracy (e.g., shrinkag ...

In this phase-I proposal, the effect of terrestrial cosmic rays on the failure rate of commercial 1200V SiC power MOSFETs will be studied. The goal of the study is to quantify the appropriate breakdown voltage de-rating needed for SiC MOSFETs subject to cosmic rays. The failure rate of SiC power MOSFETs as a function of the reverse blocking voltage will be determined and compared to failure rate o ...

The objective of this technology transfer effort is to leverage technology developed at Savannah River National Laboratory (SRNL) to develop a portable proportional counter (PC) for neutron detection. NanoTechLabs Inc. (NTL) will develop a portable proportional counter for neutron detection utilizing nanostructured field emitters. Unlike traditional proportional counters, which are typically arran ...

Current and next-generation power systems require power devices that operate at high voltages and high frequencies beyond the reliable operating limit of the present silicon- and silicon carbide-based power devices. The material properties of AlN permit power devices to operate at these extremes, promoting device shrinkage for automotive applications as well faster switching and more efficient pow ...

The Polyhedral User Mapping Assistant and Visualizer (PUMA-V) project is addressing the challenges of developing optimized computer software for heterogeneous supercomputing systems in support of physics simulations needed for bringing theoretical calculations to the level of the newest precision experiments. Current Lattice Quantum Chromodynamics (LQCD) and Lattice Beyond Standard Model (LBSM) s ...

US production of Helium, a critical and irreplaceable resource that is currently produced from a few helium-rich natural gas reservoirs, is in rapid decline as these currently viable rich reserves are being depleted. The new technology being developed herein is required to recover helium from vast natural gas reservoirs containing concentrations too low for current economic recovery. This program ...

ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

ABSTRACT: Corvid Technologies, in partnership with Clemson University"s combustion modeling group, is pleased to offer a physical sub-model evaluation and development plan for turbulent combustion applications relevant to the Air Force. We will leverage the computational resources and combustion modeling expertise from both parties to evaluate the current state of combustion modeling and then tra ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...
