The objective of this proposal is to design, analyze, and implement scalable algorithms for analysis-driven construction of high-resolution 3D terrain models from BIG terrain data sets, and to build a software infrastructure for making analysis-prepared terrain models available to data consumers on multiple platforms. Analysis-driven modeling means that the construction of the model is influence ...

This Phase I program is focused on enhancement of the performance of MgZnO based solar blind detectors. MgZnO alloys have superior optoelectronic properties with bandgaps suitable for solar blind detection. Issues related to doping and miscibility will be addressed. This will involve the use of advanced MOCVD and MBE growth techniques and consideration of both Schottky and p-n junction devices. No ...

With the advent of very high strength concrete, such as that manufactured by LaFarge, calculations that have been used historically to determine the explosive content needed to breach concrete structures have been compromised. As a result of this and other mission critical issues, the Army has indentified a need to develop a man-portable device capable of estimating the thickness and strength of ...

Obscurant materials are used by the Army to protect both the soldier as well as military physical assets. Several obscuration systems have been developed over the years to defeat threats in all areas of the electromagnetic spectrum. Current obscurant materials typically consist of off-the-shelf or processed metal particles or flakes in which key properties such as particle size and aspect ratio ...

During covert operations, the U.S. Army may be required to breach a concrete structure using a controlled explosion. When choosing the most effective charge size and placement, it is vital to perform a rapid field assessment of the material and structural properties of the target structure. However, recent advances in manufacturing high strength concrete materials (such as Ductal) may increase the ...

In military settings, vehicle engine noise can be a source of vulnerability, revealing the location of vital resources to hostile threats. Cancellation of the engine noise is necessary to safeguard many military missions and mitigate enemy threats. This proposal concerns an innovative lightweight thermoacoustic device using thin, flexible, novel materials for active noise cancellation of military ...

Electromagnetic spectrum (EMS) supremacy is vital to the success of the war fighter; spectrum dominance, however, is becoming increasingly more difficult with advances in signal processing algorithms and device technologies. Realistic training environments are essential to properly prepare the war fighter for the non-permissive, congested, contested, and dynamic spectrum that will be encountered ...

A GPS receiver based system with associated antenna array design is proposed to provide continuous information for attitude determination. This system will adapt to GPS jamming, and spoofing threats, to maintain navigation in contested environments. The approach utilizes two dimensional, beam steered arrays which point a minimum of four beams at a priori known satellite locations relative to the ...

Applied Colloids proposes the use of its proprietary nanofluid technology as an add-in treatment process for gearboxes and transmissions of military ground vehicles that would reduce the internal friction generated in them. This would reduce the vehicle fuel consumption by 2 to 3%. It would also reduce the wear and maintainance costs for this equipment. Applied Colloids will form the nanofluids ...
