A plan is presented to demonstrate the feasibility and practicality of a radio-frequency Hayes-Corron (H-C) chaos-based communication system employing an optimal spread-spectrum chaotic communication theory to achieve superior low-power, low-probability of interception, multiple-user access, and portability goals. By integrating three concepts: 1) chaotic spreading sequence generation, 2) Hayes en ...

A particle-systems approach is proposed for rendering obscurants in tactical missile scene generation. Obscurants are currently rendered using arrays of voxels, small homogeneous cubes containing concentration and temperature data. Voxels have been highly successful but they require huge data files and are very slow to render. The particle systems would not replace voxels for high-fidelity applica ...

A technique that enables new methods of obscurant modeling with faster rendering while maintaining or improving physical fidelity is proposed. the proposed technique not only exhibits the qualities of voxel based obscurants, but matches real-world data as well. The main objective from Phase I efforts will be a specification for the technique of generating physically correct and efficient obscuran ...

The chloroperoxidase enzyme from the filamentous fungus Caldariomyces fumago has applications in industrial chemical synthesis and the detection and inactivation of chemical warfare agents. Chloroperoxidase is capable of regio- and enantioselective oxygenations and halogenations of organic substrates. When performed chemically, these reactions typically require aggressive reagents and reaction c ...

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves in unbounded regions. The accuracy and/or stability of the simulations may deteriorate over long times due to the treatment of the outer boundaries via artificial boundary conditions. We propose to develop a universal algorithm and software that will correct this probl ...

With the advent of more efficient hydrogen reforming systems, a practical hydrogen source has lead to investigations on the operating characteristics of diesel (JP-8) engines with a hydrogen/syngas additive. Several sources have reported that higher thermal efficiencies and lower pollution occur when hydrogen is added to the fuel stream. The objective of this proposal is to experimentally quanti ...

The objective of this research is to develop materials that may replace the current generation of visible smoke formulations used by the U.S. military. In particular the materials must produce low flame so that they do present a fire hazard, have relatively low toxicity, and are efficient. The efficiency is defined in a figure of merit that combines fill factor, yield factor, extinction coeffici ...

The ability to direct the wound pathways following injury could provide a critical path in wound care at crucial times during the progression of healing. A promising field of study in wound healing is epigenetics; alterations in gene expression caused by mechanisms other than changes in DNA sequence. Identification of epigenetic factors and their manipulation may result in the development of nov ...

The technology, theory and fabrication of metamaterials have seen impressive progress in the last few years, and various applied fields have benefited from the flexibility of electromagnetic response that metamaterials provide at microwaves, infrared (IR) and/or optical frequencies. Negative-refractive and zero-permittivity metamaterials have been proposed for breakthrough novel applications in m ...

The technical objectives of this Phase II project are to identify unique biomarkers and produce molecular, antibody and peptide reagents that are specific for human prostate cancer progenitor stem cells. We propose to utilize the information from the Phase I award and subsequent research to develop assay reagents that would be used to develop a blood-based assay specific for circulating prostate c ...
