Tissue engineering technology is of particular import to the Army for the matter of producing tissue replacements for the repair and regeneration of various organ systems (liver, heart, muscle, lung, etc.) for wounded patients. Unfortunately, the production of masses of tissue with thicknesses greater than ~1 mm presents a challenge due to diffusion limits of nutrients into the tissue and waste ou ...

Fungal skin infections plague active duty servicemembers at elevated rates due to exposure to warm, humid climates, poor skin hygiene, and close-quarters living arrangements. We have developed a novel solution that incorporates an endophytic fungal extract with selective activity against Trichophyton species of pathogens. In addition, the selected compound has negligible impact on the organisms th ...

In this SBIR program, Omega Optics, University of Texas, Austin and Adtech Photonics propose a complete monolithic epitaxial device, with no wafer bonding, for surface emitting 2D non-mechanical optical beam steering at 4.6 micron wavelength. Two methods will be investigated: first, with slant etch normal emitters for azimuthal and elevation steering at a single wavelength using thermal phase shif ...

TransWave Photonics, LLC in collaboration with the University of Texas at Austin, proposes to demonstrate a mid-infrared 2-dimensional beam-steering photonic integrated circuit (PIC) with a passive InGaAs/InP platform where high performance mid infrared quantum cascade laser sources, low-loss InGaAs waveguides, and beam steering photonic elements are monolithically integrated. Low mid-infrared opt ...

The Lynntech team proposes to develop a Computer Vision FoolKit system that integrates cutting-edge approaches to systematically evaluate physically realizable adversarial attacks against several leading computer vision classifiers. It has been noted that most deep neural networks are demonstrably vulnerable to adversarial examples, even in the form of small-magnitude changes in intensities of the ...

The Base and Option propose applying machine learning (ML) deep learning (DL) methods to estimate the Waveguide Invariant (WGI). The ML and DL application also provide prior parameterization of the waveguide. Data fusion methods generate Energy Spectral Density (ESD) and Empirical Orthogonal Functions (EOF) to characterize the uncertainty of the sound speed profile in the water column from which t ...

TransWave Photonics, LLC in collaboration with the University of Texas at Austin proposes to demonstrate a new active region and thermal packaging configuration for the mid-wave infrared quantum cascade lasers that provide both high modal overlap with the laser active region and a dramatically reduced thermal impedance of the laser compared to the current state-of-the-art. The proposed laser desig ...

Next-generation infrared (IR) seekers will have an aerodynamically-engineered nose cone geometry with a significantly higher degree of curvature compared to conventional hemispherical domes. To prevent unwanted specular + diffuse reflections that obscure the IR focal plane array, the interior of the dome should ideally be treated with an anti-reflective (AR) layer that suppresses stray light refle ...

RDRTec with Raytheon as a subcontractor and transition partner proposes to design, develop, and demonstrate feasibility of enhanced approaches to unmanned aircraft weather avoidance using a combination of organic weather radar and electro-optics. The goal of this effort is to provide increased safety against weather hazards while minimizing unnecessary deviations by using visual cues and measurabl ...

Accurate and timely weather information for situational awareness is critical to the success of Air Force missions.To date, space-borne sensors for weather forecasting primarily include visible, infrared, and microwave instruments.While visible and infrared sensors have reached a high level of maturity and performance, those operating in the microwave region of the electromagnetic spectrum continu ...
