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. Re ...

The project is developing a new sensor technology that can measure carbon dioxide levels with precision that matches or exceeds the state-of-the-art performance, but will reduce the price dramatically, and will for the first time enable instruments deployed in remote locations to operate unattended for long periods of time. A laboratory prototype was designed, constructed, and demonstrated. It exc ...

A Weigh-in-Motion (WIM) system is being developed that will deploy in or on roadways of all types and accurately measure and report weights of crossing vehicles, including total vehicle weight and individual axle and wheel weights. The innovation in the system is that it senses horizontal (lateral and longitudinal) forces at each wheel and uses those measurements to correct for vehicle weight shi ...

U.S. automakers have invested significant resources in the research and development of hydrogen fuel-cell vehicles. However, to enable their widespread use, an additional major investment will be required to construct an infrastructure for hydrogen production and delivery to fueling stations. In order to facilitate this transition, the DOE has recommended that high-pressure hydrogen generation fo ...

To provide improved Collaborative Situation Awareness (CSA) and, ultimately, improve the Warfighter’s operational success, PEO Soldier is developing new equipment, technologies, and tactics, techniques and procedures (TTPs) that leverage the wealth of information available to Net-Centric Soldiers. Modeling and Simulation can support these efforts by providing the ability to model the effect ...

Greenhouse gas (GHG) emissions are primary drivers of global climate change. Hence there is a crucial need to quantify their sources and sinks. A powerful method to constrain source and sink strengths is the analysis of the relative proportions of isotopic variants of GHG’s in atmospheric samples like those collected globally by NOAA’s Cooperative Air Sampling Network. Measurements that are ca ...

A manufacturing process for nanostructured ultradark coatings will be developed that will enable a rapid transition of the technology to fielded Department of Defense optical systems. The process will leverage the successful Phase I effort that demonstrated the application of ultradark coatings on aluminum surfaces that had less than 1% reflectance for wavelengths between 300 nm and 10 m. During t ...

Physical Sciences Inc. (PSI) proposes the development of a processing system based on a Recursive Bayesian Classifier (RBC) for detection, tracking, and classification of biological clouds using imagery from existing uncooled thermal imagers. This solutio

While substantial advancements have been made in realizing tube based large area detectors such as the Large Area Picosecond Photo-Detector (LAPPD), there is widespread agreement in the cathode community that a higher QE bialkali cathode is possible, and that the present understanding is largely-recipe driven without the adequate control or understanding to achieve the previously observed high yie ...

The lack of lubrication performance associated with JP-8 fuel in modern diesel engines equipped with High Pressure Common Rail (HPCR) fuel systems can lead to premature performance loss and catastrophic field failure. OEM¡¦s will need to first thoroughly understand these effects and then make provisions for JP-8 fuel compatibility as engines in the Army fleet are replaced with modern engines ...
