Until now,much of theresearch usingfunctional near-infrared spectroscopy (fNIRS) has focused on tailoringasystem to detect onlyafew cognitivestatesand theapplication of theseapproaches outsidethe laboratory is not well tested. This solution provides severely limited coverage of thespacethat this technology could beapplied to,and is notarealistic path for developing neuroimagingasan operational ass ...

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 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 ...

The "Hybrid Integration of Photonics and Cryogenic Electronics with Magnetic Shielding (HIPCEMS)” effort will develop a scalable heterogeneous packaging plan which results in extreme energy efficiency information transfer at high clock rates and low bit error rate of digital data between superconducting and photonic technologies, each at 4K. HIPCEMS will feature a mechanically robust package tha ...

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 ...

Traumatic injuries account for 30% of all life years lost in the US and is the leading cause of death for people under 46 years of age. Uncontrolled bleeding or hemorrhage constitute 30-40% of trauma related deaths and are considered to be a major cause o

In common terminology, chaos refers to a state of randomness or unpredictability. Chaos has a different meaning in physics and mathematics. In physics, chaos is a structured but irregularly patterned behavior displaying an extraordinary sensitivity to initial conditions. Work done by the principals of the proposal has proven that logic elements can be built with chaotic elements and can replicate ...
