Award Data

The Navy"s mission success increasingly relies on complex decision support systems and automation. Navy command and control systems must provide the users with the right information, at the right time, depending on the context in which they are operating, and must do it in a proactive manner. Today, massive quantities of data are passed blindly between nodes, with no ability to adapt the delivery ...

Continuous physiological monitoring can provide invaluable insight into the status of the person monitored. The right sensors can provide important information related to both the physical and mental state of the subject. Although sensing modalities and the information that can be gleaned from them is a fairly well advanced science, the sensors themselves lag behind in terms of being sufficiently ...

We propose to build a two-dimensional multi-pixel infrared detector based on rectenna technology. The rectennas comprise of a micro-antenna tuned to terahertz reception and an integrated Metal-Insulator-Metal diode. This system captures infrared radiation, rectifies it and converts it to a direct current for further processing. In this Phase II project, we plan to fabricate 2-D arrays of rectennas ...

Composite materials are widely used in aircraft to reduce weight and cost, improve structural performance, and boost fuel efficiency. However, composites are susceptible to adhesive bond quality issues, including kissing bonds which may occur because of initial fabrication or service related issues. Detection of such weakened bonds requires an easily used detection approach to routinely monitor co ...

This STTR Phase II Proposal addresses the need for a low cost acoustic transmitter that combines a power amplifier, control-circuitry and an innovative transducer assembly, all at a low cost. Our approach is to use a cylindrical modal vector projector transducer which becomes part of the housing and, moreover, uses only a minimum of power to provide a sizable source level. The modal vector project ...

Submarine commanders must make complex decisions to accomplish increasingly diverse missions. Moreover, concurrent missions may involve contradictory requirements. Planning must also account for the unexpected, including equipment failures, environmental factors, or external events that impact the ship's mission(s). Since all submarine operations involve a degree of risk, the commander must b ...

This STTR aims to develop a novel method for detecting and tracking growth of cracks in rotorcraft gearbox. Aerospace structures are subject to dynamic loading. In particular, gearbox components experience continuous cyclic loading, wear and eventually develop fatigue cracks. As opposed to most other aircraft components, gearbox components are non-redundant, so a failure can have catastrophic cons ...

Autonomous systems continue to be outfitted with larger amounts of sensors that are capable of collecting extremely large amounts of data over the course of a mission. Even autonomous systems with high storage capacities can run into storage limitations when burdened with large amounts of sensor data over long mission durations. This proposal will develop a Learning-based Approach for Relevant Dat ...

This research seeks to develop a method of developing solid-state power amplifiers that operate at 300 Volts, achieve 100 Watt output and greater than 90% efficiency at 1 GHz with 10% bandwidths. We will seek to demonstrate switch-mode amplifiers that use a novel gate design with Gallium Nitride forming the basis for solid state power amplification.

21CT and CUBRC propose CEDAR (Complex Event Discovery, Analysis, and Ranking), a robust framework to detect and analyze indicators of complex activities, such as an insurgent ambush observable via myriad of simple events in multiple sensor streams. CEDAR will provide a mapping from complex behavior, such as conducting an insurgent ambush or rebuilding trust in local communities, to simple event in ...
