ABSTRACT: We propose to develop a light weight, compact, vibration-less and micro-scale cooler for space-mission conditions based on optical refrigeration using an all-fiber approach. Specifically, we will use a Tm+3-doped fiber laser to pump Tm+3-doped glass fibers, which provide the cooling action on the affixed heat source. The cooling fiber is attached to the heating sample e.g., EO-IR detect ...

ABSTRACT: The CTI/SU team proposes the Cyber Cross-Layer Optimization Publish-Subscribe (CYCLOPS) framework for design, prototyping and assessment of innovative methods for creating cognitive network architectures and protocols to achieve autonomous network resiliency in contested Radio Frequency spectra. Within this framework, the team will design metrics for estimating the benefits, costs and r ...

ABSTRACT: We propose to apply modern massively multicore processors to a key problem area of interest to the Air Force: multiphysics computational fluid dynamics (CFD) and computational structural dynamics (CSD) solvers. The capabilities of the CPU to solve these problems have been increasing steadily, but the CPU is still a general-purpose device designed to run diverse applications such as word ...

ABSTRACT: This STTR Phase I project addresses exploit attempts being mounted against applications code and modules with vulnerabilities that need to be protected. The team's strategy is to"blacken"or isolate applications and the inter, and intra communications paths between them and the lnternet using innovative algorithms developed by Embry-Riddle Aeronautical University (ERAU). We plan to ...

ABSTRACT: The key objective of the proposal is to develop sophisticated, graphical user interface driven software tools built on fully microscopic physics to design, guide and provide feedback on growth, fabrication and evaluation of semiconductor structures that provide optical gain in the critical 2.4-4 micron wavelength window. Existing technologies are severely limited by low gain, high losse ...

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: We are experiencing grand challenges to ensure that cyberspace resources and services can effectively tolerate epidemic-style cybperattacks, and manage automatically its resources and services. Currently, there are no effective commercial technologies to secure and protect cyberspace resources and services; they are mainly labor intensive (e.g., patch update), signature based, and not f ...

ABSTRACT: Crystalline semiconductor nanomembranes (NMs) possess the electronic/photonic properties of bulk material, although they are flexible, deformable, and conformable. Semiconductor nanomembranes offer unique opportunities for novel active/ passive electronic, and photonic devices suitable for vertically stacked high-density photonic/electronic integration. Silicon-on-insulator substrates. ...

ABSTRACT: The potential of scramjet engines for use by the U.S. military would revolutionize countermeasures enabling rapid responses to global hot spots. The scramjet traveling at hypersonic speed cannot use rotary power typically employed at sub-Mach velocities, while auxiliary power units and batteries add weight, volume, and system complexity. Thus, alternative power sources are sought to ai ...

We propose a metamaterial-enhanced microbolometer with strong absorption over a narrow band that is dynamically tunable over the 8-10 micron band. A single-layer photonic metamaterial consisting of a thin metal film perforated with a 2-D array of dielectric apertures will be deposited on an amorphous-Silicon layer acting as an absorber and bolometer. The metamaterial, in conjunction with planar di ...
