DESCRIPTION (provided by applicant): The objective of this proposal is to develop a less invasive long-term copulsation device to treat patients in late Class III and early Class IV stages of heart failure (HF). Chronic congestive heart failure is the largest unsolved problem in cardiac care today. There are over 5.5 million people in the United States with this diagnosis and the number of patient ...

Cyberspace superiority is a prerequisite for effective operations in all other warfighting domains. To maintain cyberspace superiority, there is a need for effective Command and Control (C2) tools to observe, plan, and execute cyber operations. Visualization is a key enabler of C2 but new approaches are required to address cyber security data sets. A principal challenge is the complexity of this d ...

Carbon dioxide is monitored with high precision at hundreds of monitoring stations, world-wide. Those measurements rely upon frequent calibration using high pressure gas cylinders, which must be certified and then shipped to remote locations. Current calibration procedures are both labor intensive and expensive. Continuous monitoring of CO2 at remote locations presents particularly difficult cali ...

Aerodyne Research, Inc. (ARI) and MIT are collaborating to extend their successful Phase I effort to fully develop and validate a comprehensive JP-10 combustion mechanism, using a novel automatic reaction mechanism generation tool (RMG) developed at MIT. JP-10 is a very attractive, but complex fuel whose combustion chemistry is poorly understood. In Phase I, the ARI/MIT team successfully developed ...

By providing size resolved compositional information, the Aerosol Mass Spectrometer (AMS) has greatly advanced understanding of aircraft particulate matter (PM) emissions. AMS data have been critical to much of our understanding of aircraft PM emissions, but in the past it has had limited utility in probing the smallest (

Computational Fluid Dynamics (CFD) simulations for combustion do not currently have the predictive capability typically found for non-reacting flows due to the prohibitively high computational cost incurred when one introduces detailed chemical kinetics. In this SBIR project, we propose a novel method, Adaptive Chemistry, to enable such detailed modeling. This method adapts the reaction mechanism ...

Assessment of CO2 exchange between the atmosphere and the biosphere remains one of the largest uncertainties in predicting carbon sequestration by vegetative uptake on a global basis. Distinguishing between photosynthetic uptake and respiratory emission of CO2 is difficult, due to the small differences between two large parameters, but crucial for determining net ecosystem exchange for CO2 betwee ...

Aerosol particles have important impacts on visibility, acid deposition, climate, and human health, although large uncertainties remain in quantifying their chemical composition and atmospheric transformations. A large fraction of the anthropogenic aerosol is generated from energy-related activities, and organic compounds are known to constitute a significant fraction of ambient aerosol mass. Or ...

We propose to realize a new class of microbolometer FPA technology with significantly reduced 1/f noise by replacing the sensing material (e.g. VOx) with colossal magnetoresistive (CMR) oxides. The program uniquely combines Agiltron's experience in novel IR imager development and leading academic research on CMR at Los Alamos National Lab (LANL). The LANL Team has developed breakthrough process ...
