Thermal barrier coatings have been widely used to provide thermal protection to superalloy components in gas turbine engines. After certain amount of service time, the coating experiences a reduction in thickness by processes such as wear, erosion and foreign/domestic object damage. When the thickness decreases below a critical value, the thermal barrier effect provided by the coating is no longer ...

Optical components for RF-photonic applications such as communication satellites, avionics, optical networks, sensors and phase array radar will require high speed, high capacity and low power. Due to the nature of crystalline electro-optic materials (LiNbO3, GaAs, InP, etc.) today’s commercial electro-optical devices do not perform well above 40 GHz. This limitation can be circumvented by utili ...

This proposal deals with advanced design architectures for realizing silicon-based reconfigurable and stackable photonic analog signal processing engines supported on flexible or flat substrates using crystalline Si-based nanomembrane technology. Silicon nanomembranes are single crystals of Si that have been released from SOI substrates and redeposited on foreign flexible or flat substrates enabli ...

Many large-scale numerical simulations can be broken down into common mathematical routines. While the applications may differ, they often need to perform standard functions such as system solves, Fourier transforms, or eigenvalue calculations. Consequently, producing fast, efficient implementations of these methods will benefit a broad range of Air Force applications. Graphics Processing Units (G ...

Many hardware trojans depend on (a) the ability of an attacker to have an accurate model of the target system and of key software used on that system and (b) identification of one or more deterministic trigger conditions with low observability (i.e., conditions that evade detection by traditional scan- or ATPG-based testing methodologies but that can be exercised on demand via external stimuli). ...

With the range and variety of radiation detectors that exist and the continuing threat of a radiological disaster in the future, the need for training of first responders and personnel in the front lines of interdiction is extraordinary and daunting. It is daunting because of the number of people across the nation that must be trained initially and who must continually maintain their training to b ...

The human body is a near perfect energy generator. Demand for energy harvesting innovation, along with technology advances in thin film thermoelectric generators and highly efficient DC/DC boost circuitry now place wearable thermoelectric power harvesting within reach. The objective of Perpetua`s Phase II proposal is to deliver an energy harvesting system for first responder applications powered b ...

The main objective of the proposed Phase II project is to leverage the technology of THz generation in resonantly-pumped quasi-phase-matched (QPM) GaAs structures, jointly developed by Stanford University and Microtech Instruments, Inc., and create a compact and power-efficient commercial THz source with a mW-level average power. This source will be continuously or step-tunable in the 0.5-3 THz ra ...

Sky Research, Inc. proposes to investigate the application of geometric diversity to Ultra-High Frequency Synthetic Aperture Radar (UHF SAR) and to analyze the effects on coverage, resolution, and detection performance. Geometric diversity can be realized with curved, circular, or spiral flight paths, or by combining multiple straight or curved flight paths into a single coherent data set. The pro ...

Sky Research, Inc. proposes to advance present capabilities for Improvised Explosive Device (IED) detection and other Intelligence Surveillance Reconnaissance (ISR) detection needs though the explicit integration of Ultra-High Frequency (UHF) synthetic aperture radar (SAR) and Light Detection and Ranging (LiDAR) technologies. LiDAR and SAR bring separate and compatible detection capabilities to IE ...
