High fidelity, large scale simulations of complex systems pose a very difficult situation to the scientist trying to understand the physical domain and characteristics of their system. Often, it is impossible to manually search through the data that can come out of these simulations, which may range from Gigabytes to Terabytes. Furthermore, it may be impossible to visualize the multi-dimensional i ...

Providing commanders with accurate, on-the-spot, clear, concise, usable information wins battles and saves lives. With incoming information from many heterogeneous sources, the focus has been primarily on determining what information to present, and visual ways of communicating the information. There has been less research on what makes information actionable, or on what additional communication c ...

There is a need for a next-generation integrative decision support system for Space Control operations. This next-generation system should provide high-level capabilities for managing case files containing evidence, expert opinions, and data relationships. The system should enhance operator awareness by highlighting salient aspects of the case file, critical relationships, and confidence assessmen ...

The monitoring of multiple UAV video sources is challenging, in part, due to the poor quality of the video received.  Significant video degrading is caused by clouds, haze, and dust in the atmosphere; jitter and blurring from the UAV platform motion; and low video resolution due to sensor characteristics and high altitude flying. Higher quality video would alleviate much of the challenge for the ...

High performance dynamic networks, which support scientific experiments with high bandwidth requirements, consist of a control plane and a data plane, neither of which, at present, is secure against cyber attack. Careless or malicious tampering with these networks could disrupt the network, invalidate data, and otherwise ruin experiments supported by the networks. Security measures ¿ fire walls ...

The oscillating water column (OWC) is a candidate technology for the economical recovery of the projected 17.5 x 1012 kW-hr energy that is available from the world¿s oceans. While the relative dynamics between the OWC system and the incident water waves are mathematically understood, computational solutions have not been used to ¿tune¿ the OWC turbine-generator sub-systems to operate where the ...

Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. These accelerators currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. This project will review available transistors, analyze high-efficiency power-amplifier techniques, and experimentally evaluate ca ...

A closed-path methane and water vapor gas analyzer ¿ which is robust, portable, has low power consumption consistent with solar powered applications, uses room-temperature lasers, and is suitable for long-term and remote field measurements ¿ is not commercially available. Yet, such an analyzer is required to support the widespread deployment needed to achieve a better understanding of the globa ...
