Social media platforms have enhanced many communities by facilitating online development of relationships, fostering collaboration, connecting friends and supporting activism. However, these platforms are also environments for people to bully and spread hate. Furthermore, adversaries of the United States and its allies have weaponized social media to spread disinformation. Intelligent Automation, ...

The development of a VCSEL capable of 100Gbps NRZ signaling over the temperature range of -40 to +85C with photonic resonant enhancement of the modulation bandwidth using photonic crystal coupling is proposed. A revolutionary change to the recent evolutionary progress in high speed VCSEL operation is needed to make the leap from 25Gbps devices to ones capable of delivering the > 60GHz bandwidth ne ...

The overall goal of this STTR Phase I project is to develop a concept to mitigate the effects of motion/vibration for a shipboard material extrusion additive manufacturing (AM) system.  NAVSEA has been installing advanced manufacturing equipment, including 3D printers, onboard ships in support of shipboard operations and to evaluate performance of the equipment in shipboard environments and in re ...

Accurate prediction of the state of boundary layers and regions of separated flows is of fundamental importance in the design of hypersonic vehicles. The ability to predict boundary layer characteristics and how these affect surface shear stress and its influence on the surface skin friction is directly related to flight performance.  This STTR is concerned with developing a system for measuring ...

Current Zumwalt Class destroyers (DDG 1000) sea chest openings are unique because they must be flush to the hull, limiting implementation of common sea chest designs (e.g., bubble shields or raised inlets). This design results in the ingestion of higher amounts of ice, debris, and air, resulting in increased maintenance costs, potential pump failure, and degraded overall cooling performance. The N ...

Hydrometeors consisting of liquid water droplets or solid particles of ice can disrupt the boundary layer near hypersonic vehicles, and ultimately impinge on the surface causing surface roughness and further altering the flowfield. To advance the knowledge of hydrometeors and their impact on hypersonic flight, it is critical, therefore, to develop practical, high-fidelity and spatio-temporally res ...

Fatigue life of parts produced by metal additive manufacturing is determined by the complex interaction of defects, surface properties, and material microstructure.  Each of these constituents is affected by the choice of processing parameters, as well as the feedstock, machine performance, etc.  In addition, stochastic events often contribute significantly to the fatigue life of individual samp ...

This STTR will develop atomically precise fabrication and measurement technology that will enable a new experimental regime to study the physics of strongly correlated quantum systems.The fabrication techniques are based primarily on Hydrogen Depassivation Lithography (HDL) which uses Scanning Tunneling Microscope technology to create atomically precise patterns of H on a Si (100) 2x1 surface in a ...

Nanohmics, teaming with CUNY, proposes to develop high-performance, metamaterial-based lenses that can be scaled up to tens of centimeters of clear aperture for ISR and other imaging applications. These high-throughput achromatic metalenses will operate across all visible wavelengths, 400-700 nm, demonstrating polarization-independent, low-aberration f/2 imaging comparable to much bulkier conventi ...

The Defense Advanced Research Projects Agency (DARPA) is seeking to utilize small reconfigurable robotic system to operate independently in unknown highly complex environments. We propose a modular reconfigurable robot, which presents several locomotion modality to handle different type of off-road environments. We proposed several configurations for the robot, which are well-suited to the type of ...
