Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

Strength and durability of commonly used bonded and bolted composite-to-composite and composite-to-metal structural joints suffer from sharp geometry variations, mismatch of elastic moduli, Poisson's ratios, coefficients of thermal expansion and thermal conductivity of the adherends, altogether causing high stress concentration and premature joint failure. The proposed work introduces several nove ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

The Air Force Research Laboratory (AFRL), Military Satellite Communication (MILSATCOM), and National Aeronautics and Space Administration (NASA) have a current and future need for advanced commercially available inherently radhard primitive cell libraries to support new designs for satellites and other spacecraft. American Semiconductor Inc. proposes the use of double gated Flexfet technology for ...

The proposed research will develop a non-equilibrium plasma source for deposition of thin films on refractory materials at temperatures less then 600K. The developed source will also have the flexibility to surface treat thermally sensitive substrates without damage. Our existing non-equilibrium atmospheric plasma source will be optimized for depositing amorphous SiC and ZrO2 thermal barrier mat ...

In presence of targets that respond to transmitter diversity such as polarization, maximization of the output signal to interference plus noise ratio (SINR) in presence of signal dependent interference and noise requires joint optimization of the transmit signal vector and the receiver filter bank. The proposed work involves the design of waveforms to exploit the spatio-temporal diversity associat ...

Detection and identification of similar class military targets can be extremely difficult, especially at extended ranges. The wide variety of deployment scenarios further complicate this effort. In reality, the sensitivity of an imaging system and the contrast of targets can be strongly reduced. There have been several approaches (hardware solutions) to overcome the problem of optical image degra ...

Taggants are small objects used to label things or people that need to be traced. Synthetic DNA Taggants are ideal for this, since very small amounts can be detected if the sequence is known, and can be disguised by natural DNA in the environment. Known protocols for DNA amplification (e.g. PCR) allow for very sensitive DNA detection, but suffer from disadvantages: the apparatus is not very portab ...

SBIR Phase-I program investigation into a Wide Band Gap (WBG) technology and its ability to meet the Air Force specifications for a High Power Amplifier (HPA) demonstrated unequivocally the feasibility of meeting/exceeding this objective with GaN HEMT devices. The 50W power achievable over a multi-octave bandwidth of [200MHz-1,000MHz] and [1,000MHz-4,000MHz] with efficiencies [PAE] exceeding 40%, ...
