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 ...

Vescent Photonics proposes to develop a compact laser system and integrate it with a cold-atom micro primary standard developed under the DARPA IMPACT program. In phase I we will investigate performance enhancements resulting from immobilizing the cold-atom sample with an optical lattice formed from an optical field whose wavelength is chosen to minimize the differential light shifts between the s ...

Integrally bladed rotors (IBR), also called blisks, are becoming increasingly common in the compressor and fan sections of modern turbine engines. The integration of the blades and disks into a single part has the advantages of reduced part count, reduced weight, increased reliability, and increased performance. However, a drawback of this technology is that individual blades cannot be easily repl ...

The overall objective of the Phase I and Phase II proposed effort is to design and demonstrate the ability to develop a high-speed shock tolerant composite flywheel energy storage system (FESS) using a low cost manufacturing process. The Phase I tradeoff design studies will assess the FESS size, operating speeds and material requirements needed to achieve the energy density levels and charge/disch ...

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.

Network-centric command and control of complex military missions (e.g., anti-submarine warfare, collaborative mine hunting, etc.) calls for cost-effective designs that can dynamically tradeoff multiple conflicting objectives. Often these optimizations have to be carried out at a higher level, and the associated control directives have to be disseminated down to a distributed system, thereby, influ ...

The key innovation of this proposal is to develop an adaptive and scalable network resource virtualization framework. The framework employs simple yet efficient mechanisms to deliver a comprehensive network resource virtualization solution through network virtualization, service discovery/advertisement, and service differentiation in mobile ad hoc networks (MANETs). It uses local caching to facili ...

The exponential growth of text-based communication associated with the Internet has lead to a vast increase in the amount of unstructured messages that open source intelligence needs to process. This increase has lead to the need to develop methods for facilitating the detection of deception in various forms of text-based messages, from chat rooms, emails, weblogs, to text messaging. Methods are r ...

A unique type of air lubricated thrust bearing called a Wave Bearing is proposed to assist a rolling element bearing to carry the thrust load and to improve the bearing’s life when used in a micro gas turbine engine. The Wave Bearing technology will provide improved reliability, safety and life compared to rolling element bearings used alone, as well as to allow simplification of engine design a ...

Electromagnetic launchers or rail guns are a key component of the Navy’s all-electric ship of the future, but they lack the durability required for repeated firings. TDA Research and the University of Nevada, Reno (UNR) are developing a tough, durable and conductive refractory metal coating that will protect the copper alloy conductors (rails) from the extreme heat and wear conditions inside the ...
