DESCRIPTION (provided by applicant): We propose to develop a compact, cost-effective Traveling Wave Tube (TWT) amplifier at 263 GHz with 50 W of peak power, 5 W of continuous wave power and 5% instantaneous bandwidth for application in Dynamic Nuclear Polarization (DNP) enhanced solid-state and solution-state NMR and Electron Paramagnetic Resonance (EPR) spectroscopy. With DNP, the inherently smal ...

Project SummaryAbstract We propose to develop aT compact and portable hybrid magnet with high homogeneityandltppmandT of sweep rangeThe magnet system will be used in Overhauser Dynamic Nuclear Polarization experiments in the X Band for studying water dynamics in molecules and other analytical chemistry applicationsIn Phase Iwe will designbuild and test a prototype magnet to meet the above stated r ...

Eye safe 3D Imaging LIDARS when combined with advanced very high sensitivity, large format receivers can provide a robust wide area search capability in a very compact package. This search LIDAR concept, when deployed on UAS, can provide target detection, tracking and identification of sufficient quality to enable search and avoid actions when other air traffic flies near UAS platforms in the Nat ...

Abstract In the USAlzheimer s diseaseADis the single most expensive diseasethe only disease in the top six for which the number of deaths is increasingThe greatest cost contributors are frequent hospitalizationswhere falls are the largest culpritand frequent need for assistance with the activities of daily livingFall safety systems show the potential to reduce costs and increase quality of care by ...

Despite many innovative analytical and simulation techniques over several decades, there remains a disconnect between available and desired technology needed to model liquid metal flows in fusion relevant conditions. Simulation software become inaccurate or very inefficient when modeling situations with high magnetic field interaction, applied volumetric heat loads, two phase effects and turbulenc ...

Abstract SignificanceIn this SBIR projectwe propose to improve the performance of InSighta machine learningbased sepsis screening systemin situations of limited training data from the target clinical siteThe proposed work will make possible prospective clinical deployments to sites which are smaller or lack clinical data repositoriesby significantly reducing the amount of training data necessary d ...

Theater missile threats often fly through and maneuver at high altitudes, where their signature can substantially change. New chemical signature mechanisms and non-equilibrium conditions will become important. The new mechanisms change the appearance of threat signatures and must be taken into account when developing detection, track, and guidance sensors and algorithms. Spectral Sciences Inc. (SS ...

DESCRIPTION Cryptococcal meningitis CM continues to be a significant cause of mortality among HIV positive individuals and a major worldwide health concern The estimated mortality rate for HIV infected acute CM patients is within months after infection in North America despite patient access to good health care resources In sub Saharan Africa alone the effects of CM are devastating ...

Parts manufactured by additive manufacturing (AM) typically suffer from a combination of defect types that can inhibit the functional performance of a part. Most AM parts inspection methods are destructive, time-consuming, complex, expensive, do not perform in-situ, and are not easily applicable in space. This Phase I SBIR proposes to develop a non-destructive evaluation method based upon acousti ...
