A simulation tool is proposed to model and simulate the wind fields, turbulence fields, and the unsteady dispersion of NCBR substances in urban areas on the building to city blocks scale. This Computational Fluid Dynamics (CFD)-based approach has beenshown to accurately simulate the urban wind and turbulence fields with minimal approximations, and has been demonstrated by modeling the flow fields ...

Large X-ray generators using gas fill loads are a key element in the DTRA simulator program. Consistent relative timing between the injection of the gas shell and the generator current pulse is crucial to producing consistent, high-yield x-ray pulses.To that end HY-Tech proposes replacing existing high voltage trigger pin technology, with a sensitive, all fiber-optic heterodyne interferometer ba ...

U.S. military communications and weapons systems are reliant on electronics systems that are highly sensitive to external electromagnetic (EM) threats, whether from intentional or environmental sources. In order to protect from these external EM threats, high levels of electromagnetic interference (EMI) shielding are required. Significant advances in materials technology and manufacturing, howev ...

The objective of this SBIR program is to adapt NanoSonic"s high temperature, ballistic resistant HybridSilTM nanocomposites for use as next generation potting materials with exceptional thermal durability, g-force resilience, and negligible variation (

Adaptive Methods and Applied Research Laboratory at Penn State are developing a hierarchical inference approach for multi-modal unattended ground sensor (UGS) networks. that will enable significant performance gains via integrated machine learning techniques, to include In situ performance characterization and automated adaptation to site-specific environmental characteristics; unsupervised learni ...

The ultimate goal of this effort is the development of advanced radiation hardened material systems and technology solutions for implementation into both silicon and compound semiconductor technologies at the nanotechnology feature sizes through the use of a gridded capacitor research methodology. To accomplish this, our team proposes to identify, fabricate, and electrically characterize both pre ...

Improvised Explosive Devices (IEDs) are a dangerous and effective weapon system that today’s military warfighters and innocent civilians regularly experience. IEDs are created with randomly assembled materials and their payloads may include projectiles, biological toxins, and other dangerous items that can cause injury or death to personnel and equipment. Detection and neutralization of these we ...

Reliable automated pattern recognition in the current system is limited by excessive noise and clutter combined with insufficient and/or ambiguous features. Our team consisting of AcornSI and Leidos thus propose a multi-step approach based on the combined effects of improved detection, feature extraction, phase identification, and global association. A key innovation here is creating a new classif ...
