Early detection of corrosion or the advent of corrosive environments in nominally protected assets, and monitoring its extent can help control corrosion initiated failures and predict the degradation or useful remaining life of utility pipeline infrastructure. Although preventive maintenance and periodic visual inspections are utilized to monitor damage and assess costs of corrosion, an autonomous ...

With the advances in solid-state electronics and optoelectronics, ultra wideband radio frequency receiver designs are now practical. One of the consequences of these large bandwidth waveforms is the very high range resolution that results. Various architectures of receivers have been proposed for the ultra wideband applications, but most popular architectures among them are heterodyne, homodyne, l ...

Energetic ionic liquids (EIL) represent a new, and potentially revolutionary development in propulsion chemistry. These salts, with unique attributes of surface tension, vapor pressure, thermal stability, and reactivity are leading candidates for low-toxicity, reduced hazard replacements of conventional (hydrazine based) monopropellants. C3 Propulsion, in collaboration with the Center for Green Ma ...

Emerging drug resistance in infectious threats poses a health risk for deployed forces. The primary objective of the Phase I effort was to enable the development of a sustainable drug discovery effort to continually generate lead compounds for discovery and derivative synthesis. Successful completion of Phase I demonstrated the utilization of a novel source of lead compounds, validation of two hi ...

Warfighters are increasingly relying on technology equipment to ensure safety, mission effectiveness, and situational awareness. This equipment increases the capabilities of warfighters but also adds to their weight burden. This excess load could cause significant stress on the musculoskeletal system and lead to physiological deficits. The overall objective of the proposed project is to develop a ...

The computational grid generation process remains a troublesome bottleneck in development of aerodynamic databases for complex geometries and multi-body configurations. The ability of Cartesian-grid based methods to perform automatic mesh generation and dynamic mesh adaptation allows for substantially reduced manpower, time and cost. The advantages of octree-based Cartesian-mesh methods have been ...

In this STTR project, an efficient and high-fidelity computational module to predict non-gray radiative transfer will be developed and validated. The proposed hybrid approach to solve the radiative transport equation (RTE) is a combination of the spherical harmonics (PN) method and the Monte-Carlo method. Non-gray gases will be treated using the full spectrum correlated k-distribution (FSCK) metho ...

CompuTherm, LLC in collaboration with Oak Ridge National Laboratory proposes to develop a modeling tool that can be used to understand the effect of Ti, Zr, and Hf addition on the improvement of ductility of the (Mo) phase in the Mo-Si-B system. The tool will be developed by integrating thermodynamic modeling with mechanical testing. Thermodynamic descriptions of the Mo-Si-B-X (X=Ti, Zr, Hf) syste ...

Recent developments have made clear the strong potential of Micro Air Vehicles (MAVs) for a wide range of surveillance and reconnaissance missions, particularly if the challenging but critical hovering capability can be achieved. Implementation of practical hovering MAVs, however, requires breakthroughs in understanding of the complex MAV flow environment as well as development of practical desig ...

Photonic links and networks offer numerous advantages to analog RF systems including inherent wide bandwidths, a harness exhibiting a reduced size, weight and improved flexibility, and nearly lossless signal. Current all-electronic delay line systems based on microwave components suffer from high signal loss and dispersion as well as large size and weight. An efficient way to achieve true-time-del ...
