ATA Engineering has developed a wavelet-based damage squeezing methodology for generating optimally compressed fatigue test signals that produce an equivalent amount of fatigue damage in a predictably reduced amount of time compared to the baseline (uncompressed) signals. Fatigue-critical signal characteristics (e.g., magnitude, phase, frequency, and sequencing relationships) are identified in the ...

For effective protection against radiated threats, it is important to understand not only the physics of the threats, but also to quantify the effects they have on mission-critical electrical systems. Radiated vulnerability and susceptibility testing requires delivery of high peak power and peak electric fields to distant targets. The most practical solution to simulate such environments on large ...

Improving capabilities of telemetry systems for next generation e.g. (MOKV) missile defense launch vehicles, kill vehicles, and test/target vehicles subsystems can transform operational testing of such systems and has the potential to increase capabilities of systems that rely on radio communications. As these systems, and their test scenarios become get more complex they will require unprecedente ...

Recent advances in the hypersonic system capabilities of adversary nations threaten the battlespace supremacy of US forces. Missile defense systems capable of extended high-g maneuvering at stratospheric altitudes and hypersonic Mach numbers will provide the MDA with additional flexibility in defending the US against emerging hypersonic threats. A key enabling technology for the deployment of such ...

This Phase-II STTR proposal proposes the use of a new class of diamond-seeded solid-state material system for the manufacture of virtually all packaged intense heat-generating solid-state electronics in X-band and Ballistic Missile Defense radar components and systems. In this proposal wherein much preliminary (also MDA-funded) work has been demonstrated hitherto by the authors, Gallium Nitride-on ...

We propose to develop a prototype of a novel spintronic spectrum analyzer using an array of nano-scale magnetic spin-torque detectors. The operation of the proposed spectrum analyzer is based on the recently discovered effects of spin-transfer torque and spin-diode effects in nano-scale magnetic multilayered elements, the fabrication of which became possible due to the recent advances in nano-fabr ...

As unmanned aircraft systems (UAS) become more prevalent there is an increasing desire to automate UAS navigation and control. To enable future UASs to perform a wider variety of missions, they must be able to complete autonomous relative navigation to accomplish missions. Current technologies rely heavily on GPS measurements, which are undesirable since GPS signals may be unavailable in many DoD ...

Treatment of water with ultraviolet (UV) light, which destroys target DNA of microorganisms, is the safest, most reliable, and sustainable way of freeing water from microbial contamination. This process is desired in place of chlorination and is widely used in the US for wastewater treatment. We propose the development of a highly efficient UV LED with emission at 265 nm, with EQE>30%, and WPE>15% ...

The Phase 2 development will yield a prototype Cognitive Data Sampling (CDS) system for 2 RF bands to fully demonstrate the capability of the underlying technology. This will include the development of RF antennas, RF signal conditioning for the bands, CDS analog to conversion module and a processor module. The processor module shall be comprised of a Commercial Off-The-Shelf (COTS) module that in ...

Realistic surgical simulation requires a combination of representative tissue geometry, accurate tissue material properties and lifelike tool-tissue interaction forces. Recent advances in computational power and imaging modalities have provided the capability to represent the anatomical details required for surgical training; however, the mathematical models which govern the underlying tissue pro ...
