The use of the heat of vaporization of the coolant can significantly reduce the required flow rate, and this reduction flows down throughout the thermal management system. Two-phase systems, however, are subject to buoyancy effects which can make them vulnerable to high-g maneuvers of military aircraft. Two-phase microchannel coolers can be designed such that surface tension effects dominate buo ...

Although great strides have been made in the development of simulators for training technical and teamwork skills, substantially less progress has been made with regard to their assessment. Typically, skills and performance are assessed by an expert observer using a Likert-type rating scale with anchors ranging from low to high. However, such methods are extremely coarse, and often provide little ...

Locomotives weigh up to 240 ton each. -Rail cars can weigh flom 30 ton (empty) to 140 ton (loaded). Track construction and maintenance equipment, earthmoving plant and haul tiuaks can all weigh l0,s of tons each. When a 200-lb worker 'arguer;' with any of these equipment they lorse. Rail road and yard workers can, literally, be sunounded by these very large, heavy and potentially dangerous pieces ...

ABSTRACT:Establishing timely, accurate, and comprehensive Space Situation Awareness (SSA) requires analytic methods that put into context the information drawn from multiple data sources. A vital feature of an SSA system is the capability to predict, and understand, space-based activities that might threaten our satellites. The Activity Learning and Inferencing for Space Situational Awareness (ALI ...

In our Adaptive Management and Mitigation of Uncertainty in Fusion (AMMUF) project, we will model the entire multi-sensor fusion process as a probabilistic model and reason about the different design and algorithmic decisions that can be made by system engineers. This fusion model will use standard fusion system representations and ideas from statistical relational learning field to create flexibl ...

ABSTRACT:The US Air Force trains JTAC and other combat personnel using video immersive simulations. However, it has proven difficult to include night vision training because of the inability of projectors to drastically change light levels. Triton systems working with key suppliers and subject matter experts is developing an innovative screen which can be electro-optically modulated in reflectance ...

Reactive Innovations, LLC RIL) proposes to develop a new ceramic pebble material composition, with high thermal conductivity, for use in nuclear fusion breeder blankets. The Phase I effort will be used to develop processes for optimizing the base powder and forming high density ceramic pebbles from the proposed material. The Phase I will further be used to characterize the pebbles for size, shape, ...

Ensuring safety and public acceptance of Geologic Carbon Sequestration GCS), a preferred means of mitigating CO2 emissions from fossil-fueled plants, requires novel cost-effective tools and methods for monitoring, verifying, and accounting MVA) to detect any CO2 leakage from sequestration reservoirs. Identifying leaks is challenging because they are difficult to distinguish from the varying natura ...

ABSTRACT:In this proposal for SBIR program (phase-II), Test Devices, Inc, in conjunction with its industry partners Pratt & Whitney and Mechanical Solutions, Inc., will leverage its experience in the domain of high temperature full component and subscale testing to develop a prototype testing facility capable of conducting tests that will evaluate components under more realistic service environmen ...

ABSTRACT:Cyber operators face a deluge of data about complex networks and need to efficiently identify, analyze, and mitigate anomalies. They are overloaded with information, and are often faced with situations that require immediate action to mitigate network effects. While computational techniques such as filters and fusion algorithms can help, the dynamic nature of cyber operations means that d ...
