The current produced in electrochemical galvanic cells is primarily dependent on the rate of the electrode reactions where the cell's anode is less negative, supplying less energy than thermodynamically predicted, and the cell's cathode is less positive, supplying less energy than thermodynamically predicted. Reduction of electrochemical overpotentials in electrochemical systems has been the prim ...

Metallic additive manufacturing (AM) is an attractive technology for the production of lethality test articles due to the potential for significantly reduced lead time and manufacturing cost.However, in order to be effective in providing accurate lethality data, the properties of the AM material have to match closely the properties of conventionally manufactured alloys found in real threat targets ...

Sciperio with team members Georgia Institute of Technology and Centecorp have teamed up to develop an Additive Manufacturing Composite using nano and micro fillers. The team will develop multi-scale models that are supported by experimental characterization for advanced 3D Printable materials. Inelastic response of high strength hierarchical structures composed of engineered materials and specif ...

High-fidelity trajectory propagators are fundamental to the simulation and analysis of launch vehicles, missiles, and satellites. Applications in fields ranging from missile threat analysis to flightpath optimization seek fast and accurate solutions to large numbers of trajectories in federated simulation environments. Due to their robustness, well-known properties, and straightforward implementat ...

We propose an innovative mathematical approach to the analysis and design of multi-function adaptive antenna systems. It uses the idea of signal fragmentation that has passed significant prior testing and employs the methods and results from sampling theory, approximation theory, and numerical optimization. The fragmentation of a signal into a combination of short elementary pulses (wavelets) allo ...

Accurate real-time waterborne pathogen detection is of paramount importance to security of U.S. military forces and installations. Fieldable high-throughput pathogen concentration is a critical analytical need for enhanced detection performance. Existing concentration methods are time-consuming, bulky, labor-intensive, power- and reagent-hungry, and consequently ill-suited for battlefield deployme ...

Hypersonic missile defense systems are being designed to reach global threats. During flight, external surfaces are predicted to reach temperatures in excess of 2200C. As a result, innovative, high performance thermal protection systems (TPS) are of great demand. Among ultra-high temperature ceramics (UHTC), it is well known that ZrB2- and HfB2-based materials have high melting temperatures and ...

The team proposes a 3D SAR algorithm based on the principles of radar tomography, which allows for transmitters and receivers to be arbitrarily located in a 3D volume. Data is collected and the output is a complete true 3D image of the reflectivity scene. The tomographic SAR provides detailed features on both horizontal (e.g., flat terrain) and vertical (e.g., building or canyons). With a proper ...

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens'principl ...

The intelligence community still cannot satisfactorily answer critical fundamental preparation, planning, and execution questions about the environment in which US and allied forces operate and the people they seek to persuade. There is a vast amount of information, almost all of it unclassified, which characterizes population identities and interrelationships in terms of beliefs, values, interest ...
