ABSTRACT: This proposal seeks to develop a novel tool wear monitoring technology using a neural network-based observer. In this methodology simple models of the wear process and another related machining process, such as force, are developed. The model development does not require lengthy analysis or experimentation since the methodology inherently accounts for the uncertainty in the models. The ...

ABSTRACT: The Space Plug-and-play Avionics (SPA) initiative is designed to improve the ability of the US military to respond to rapidly changing operational needs by creating, integrating, and launching a new spacecraft in less than one week. This would provide major benefits to war fighters on the ground, in the sky, and at sea. SPA-1 ASICs using I2C as the transport interface will likely be t ...

ABSTRACT: Flight tests of hypersonic maneuvering vehicles are a challenging but necessary endeavor. While ground tests and numerical simulations can provide important guidance regarding vehicle performance, they are both limited in their reach. Likewise surface-based measurements during flight tests provide valuable information, but do not provide sufficient insight into the complex flowfield t ...

In this STTR proposal, we propose to develop a cost-effective and high-fidelity nanoimprint process for the fabrication of integrated photonics devices. VLSI photonics applications require a hig-level of control on device-to-device uniformity. Nanoimprint lithography (NIL) holds promise to overcome the current technological challenges in lithography while being cost effective at the same time. One ...

ABSTRACT: A Health Monitoring Sensor for Solid Rocket Motors (SRMs) uses actual polymeric components of propellant in a tiny new sensor called AgeAlert. These sensors will provide real-time data corresponding to aging of the propellant. The sensors are mounted external to the propellant and automatically track degradation passively without electrical power until interrogated. They are extremely ...

Historical methods of reliability assessment are less and less effective as device sizes shrink. Larger sample sizes and longer duration tests are increasingly needed. At the same time, efforts to continue scaling semiconductors to ever smaller geometries is leading to an explosion of new device structures, materials and processes. The cost of testing these innovations is becoming a major barrier ...

ABSTRACT: This Phase I proposal will meet the Air Force requirements for smart scalable miniaturized batteries with high energy density, safety, and reliability. The battery design allows for energy densities in excess of 800 Wh/L and solid state cells are capable of extremely high cycle life, and extended operating temperature range. The lithium cell proposed is fabricated using low cost produc ...

ABSTRACT: Propagation Research Associates, Inc., (PRA) and the Georgia Tech Research Institute (GTRI) are teamed to propose an innovative holographic receiver and processing technology for enhanced radar electronic protection. PRA/GTRI will investigate applying holographic processing to Synthetic Aperture Radar (SAR) and Electronically Scanned Arrays (ESAs) in order to mitigate interference such ...

ABSTRACT: The behavior of the Chalcogenide based ion-conducting memristor lends itself for use as an element in a simple neuromorphic computing circuit. The reaction of a circuit to an external stimulus may be the result of its ability to learn from previous similar, yet unrelated exposures to environmental stimulus. A highly specialized variation of the memristor, previously developed by the Ad ...

ABSTRACT: Current air, ground and space networks are very dynamic with large-scale mobility needing human in-the-loop configuration to adapt to unforeseen situations. Humans and current automated systems cannot reconfigure consistently or fast enough. This leads to network performance not meeting mission needs. Airborne, space and ground networks are very dynamic, complex, and hard for the cur ...
