As System-of-Systems (SoS) become more complex, interactions and latent emergent behaviors become difficult to identify and control. Unmanned Autonomous Systems (UAS) are a prime example of SoS that are both critical and difficult to assure. Drawing upon prior work into multi-criteria decision making (MCDM), DeVivo AST has developed TOP Score, a software tool that facilitates the modeling and anal ...

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: Traditional multidisciplinary solvers function by solving the individual governing equations on computer clusters. In the case of aero-elastic Fluid-Structures Interaction (FSI) simulations, individual solvers have disparate requirements for optimal performance. CFD codes use iterative schemes and distributed memory, while CSD codes, use direct linear-solvers and utilize shared memory t ...

ABSTRACT: Electromagnetically-resonating infrared metamaterial elements may be used to control the phase of emitted radiation across a planar surface. Such a coated surface can be designed to produce a highly directional emitted wavefront from a large aperture high-angular-resolution array. Active angular control may be achieved using electronically-tunable metamaterial elements. Like all phased- ...

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: The Air Force is currently seeking improvements in capacity and responsiveness of Thermal Energy Storage (TES) systems. Current research and development with Phase Change Materials (PCM) in carbon foam and pelletization of metal (i.e. copper) encapsulated metal hydrides seek to overcome these limitations by increasing the thermal conductivity (i.e. copper, carbon) while also increasing ...

ABSTRACT: Fresnel-zone lens can meet many of the Air Force's requirements for conformal aperture technology including light-weight, large aperture size, and the ability to conform to a curved surface. However, aberrations limit the effective field-of-view of static Fresnel-zone lens, and the spectral performance is limited to a narrow band. A tunable Fresnel-zone lens with variable-zone-radi ...

ABSTRACT: This Phase I STTR effort will demonstrate an ultra-compact, lightweight spectrometer with no moving parts for the mid-infrared wavelength region. The planar integrated device will feature bound electromagnetic waves, known as surface plasmon polaritons, in the mid-IR spectral region. This range is ideal for chemical identification based on the vibrational spectra known for most molecu ...

Pikewerks'Protection for Industrial and Environmental Controls from Exploitation, or PIECE, will be a cross-platform suite of capabilities providing anti-exploitation and anti-reconnaissance for Industrial Control Systems. PIECE will provide a suite of capabilities for Windows, Linux, VxWorks, and legacy devices that ensure survivability of critical infrastructure equipment. Anti-exploitation ...

The U.S. Air Force is developing a catalytic thruster for advanced high density-specific impulse green monopropellants. The temperature and pressure generated in a green monopropellant thruster is much higher than with conventional hydrazine monopropellant, resulting in degradation of the catalyst. Therefore, developing and applying a model for predicting catalyst degradation and thruster performa ...
