Fuels for Army use undergo rigorous analysis to determine many chemical and physical properties before they are used in Army vehicles. The property of fuels to produce smoke or soot is one such specification used to determine fuel quality. Smoke production of a diffusion flame produced by a kerosene fuel can be correlated to the chemical composition of the fuel. Unfortunately, the standard used to ...

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 ...

Leveraging Agiltron"s industrial leading developments and production of Raman instruments, external cavity laser and nonlinear optical components, we propose to develop a new class of high performance compact deep ultraviolet (UV) laser for Raman spectroscopy. The approach is closely coupled with recent progress in GaN blue laser and external resonator enhanced second harmonic generation (SHG) to ...

Bridger Photonics and the University of Arizona will develop a passive multi-band compressive sensor for imaging and object recognition applications. The Army has identified a need for multi-band imagery for intelligence, surveillance and reconnaissance missions among others. Multi-band systems offer enhanced discrimination capability and the ability to perform in adverse conditions (at night, smo ...

Very compact, robust, and low cost multi wavelengths burst lasers for standoff CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive) detection and identification are proposed. Although a single focused laser pulse on target can do the detection, the probability of hitting the right contaminated spot is low. Therefore, scanning a laser pulse train will cover a larger suspected contamin ...

Q-Peak Inc., in collaboration with The Johns Hopkins University (JHU), proposes to develop an extremely compact, air-cooled, lightweight, multi-wavelength, burst-mode laser based on the combination of a Q-switched, Nd-doped, oscillator-amplifier laser, and efficient, robust nonlinear optical frequency converters.

This proposal is to develop a High Risk Rapid Ethnographic Assessment Tool (HRREAT) that will provide commanders and their staff with a fully-integrated, user-friendly suite of tools for the rapid collection, management, analysis, modeling, and visualization of ethnographic data in denied areas to enhance planning and decision making activities. Ethnographic data has become highly important in ...

Obtaining support from the local population is crucial for successful counterinsurgency (COIN) operations. US forces often fail to adequately understand the ethnographic characteristics of foreign populationswarfighters need access to ethnographic methods which help them to rapidly capture and interpret cultural, social, and economic data. A warfighter in high-risk areas needs easy-to-use tools th ...
