ABSTRACT: The damage and loss caused by attacks and security breaches have drawn attentions to develop secure and reliable systems for embedded systems. Compared to their desktop counterparts, embedded devices are facing more security challenges, such as the more possible physical access to a target device and more constrained computing environment (e.g., limited RAM and CPU power). Together, the ...

Multi-processor computing systems are growing in capacity and usage. They encompass multiple, distributed implementations as well as heterogeneous, embedded computing architectures. The processing density enabled by such approaches holds promise for unmanned combat air vehicles (UCAVs) with their plethora of mission sensors and command and control processing requirements. However, the software ...

Modern processor design is trending increasingly toward multicore architectures. This is problematic for programmers because writing a correct parallel program is known to be difficult compared to writing the equivalent sequential program. Additionally, a wide body of sequential code has already been developed that cannot exploit the power offered by these new cores because it was written in a s ...

In the Phase I portion of this STTR, Securboration and renowned multicore expert Dr. Frank Mueller from North Carolina State University designed, developed, and benchmarked the proof-of-concept Pico-kernel Adaptive and Scalable Operating-system (PICASO) for many-core architectures. The Securboration Team took a scientific, experimentation-based approach to identifying and resolving shortcomings wi ...

ABSTRACT: Under the first phase of the program, Plasmonics Inc. and Sandia National Laboratories investigated a range of surfaces that yield non-Lambertian emission profiles in the thermal infrared. The second phase of this program will further maturate the designs developed in the first phase of the program. With the vast majority of the analytical work complete, focus in the second phase will b ...

ABSTRACT: RNET and The Ohio State University propose to use algorithmic modifications and multi-level parallelization techniques and tools to improve the scalability of the aero-line/aero-elastic coupled CFD/CSD codes relevant to the DoD/AF (e.g., CREATE/Kestrel). The optimizations will address inter-node and intra-node parallelization to better target emerging compute architectures (e.g., multi ...

ABSTRACT: One of the Air Force main interests is to improve the antireflective (AR) optical properties of polycarbonate by exploring new coating materials or coating techniques to eliminate delamination and stress cracks due to the mismatch in the coefficient of thermal expansion between the coatings and the polymer substrates. SwRI and INTER Materials are in a unique position to assist the Air F ...

ABSTRACT: The leading errors in computing future positions of satellites in Low Earth Orbit are generally due to inaccuracies in the thermospheric density and the prediction thereof. The use of Dynamic Calibration Atmosphere has reduced these traditional sources of error and variations seen in ballistic coefficients can now be attributed to unmodeled satellite frontal area changes. When the orb ...

ABSTRACT: For this Phase II STTR effort, Prime Photonics and Virginia Tech propose to demonstrate a fully packaged hybrid photovoltaic/magneto-thermoelectric (PV/MTG) panel with improved energy conversion efficiency designed for solar powered air vehicles. In addition to acting as an active thermal backplane for the PV, the MTG is designed to maximize thermal to electrical conversion from the av ...

ABSTRACT: This Phase-I research effort is designed to forward the engineering investigation of the dynamics and control of turbulent combustion in high-pressure combustion systems by developing a set of game-changing nonlinear analysis tools that can significantly improve the post-processing speed and intelligent data mining of large numerical or experimental data sets. Moreover, a system based o ...
